Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic high speed centrifugal barrel polishing machine.

A polishing machine having a polishing tank and having a mechanism for mixing a polishing material and a polishing material therein and rotating or vibrating them to perform a polishing operation is generally called a barrel polishing machine. Depending on the form and function, barrel polishing machines are well known as a rotary barrel polishing machine that rotates a single polishing tank in an upright, horizontal or inclined position, and a vibration barrel polishing machine that applies vibration to the polishing tank to perform polishing. Is. However, from the viewpoints of the size of the polishing scale, the polishing function, and the processing efficiency, a model superior to the above high-speed centrifugal barrel polishing machine that utilizes the centrifugal force generated when the barrel rotates has not yet been developed.

2. Description of the Related Art An orbiting plate fixed to an orbiting spindle, a plurality of rotating shafts provided perpendicularly to the orbiting plate, and an abrasive material and an abrasive material inlet / outlet hole rotatably supported by the rotating shafts. A polishing tank, a polishing tank lid that is openably and closably fitted in the inlet / outlet hole, and a control mechanism that rotates the polishing tank in a direction opposite to the rotation direction of the revolution plate and makes the rotation cycle of both the same during polishing. Conventionally, there has been a high-speed centrifugal barrel polishing machine that performs polishing by rotating the revolving plate and the polishing tank at high speed.

In a high-speed centrifugal barrel polishing machine, particularly automatic control of the rotating polishing tank, that is, automatic opening and closing of the polishing tank lid, is performed by rotating both the revolution plate on which the polishing tank is installed and the rotation axis of the polishing tank at high speed. In addition, since the scale of the polishing machine itself is large, it is inevitable that considerable vibration will occur, and automatic control by precision equipment is almost impossible. For this reason, the automatic opening / closing control of the polishing tank lid by a structural means has been one of the central technical problems in the conventional high-speed centrifugal barrel polishing machine.

As an overview of the known art in this field, that is, in the automatic opening / closing device for the polishing tank lid of the high-speed centrifugal barrel polishing machine, many of them are premised on the upright operation of the polishing tank during polishing, but in terms of polishing efficiency. It is much better if the polishing tank is horizontally operated.

[0005] As a typical conventional example, the upper and lower end surfaces of a cylinder are used as a polishing tank lid, and the lid is pressed against the polishing tank by pressing the free end of an arm (Japanese Patent Publication No. 62-43829), and the revolution plate itself is used. Inclinable type (Japanese Examined Patent Publication No. 2-58057, Japanese Examined Patent Publication No. 3-21891, etc.) and equipped with a roller for rotating the polishing tank lid according to the rotation of the polishing tank.
26611), a rotary plate on which a polishing tank lid that is rotatably cantilevered is provided with a notch, and the rotary plate is slidable in the axial direction of the revolution spindle (Japanese Patent Publication No. 4-43732) and the like. is there.

[0006]

However, in the prior art, only an example in which several tanks or all tanks are simultaneously opened and closed is found, and depending on the case, all tanks or several tanks are simultaneously opened or closed, or each tank is optionally opened and closed. It was impossible to choose.

Looking at the conventional example of the revolving plate tilting type, as long as the polishing tank rotating at a high speed is included in the machine, it is structurally required to have a durable structure against vibration or impact.
In addition, when a sorting machine for the polishing material and the polishing material and a stocker or a bucket are mounted, the size of the polishing tank itself becomes significantly smaller than the size of the entire machine body. Further, in that case, it is unavoidable that the polishing tank is located at the upper part, so that the center of gravity of the entire machine body is located at the upper part particularly during polishing, and vibration of the entire machine body due to operation is large.

As a result of these, in the conventional example, the polishing scale per machine is smaller than that of the machine body,
On the other hand, there was a problem that the production unit price per machine was high and the breakdown was likely to occur.

Further, when the polishing object and the polishing material are carried in or out, if the polishing tank is upright, a shock is applied by dropping, so that the polishing object may be damaged.

In view of the above problems, the present invention makes it possible to select the automatic opening and closing of the polishing tank lids for all tanks or several tanks simultaneously or one tank at a time, and carry out the polishing object and the polishing material. To provide an automatic high-speed centrifugal barrel polishing machine that avoids the polishing tank from standing upright so that they can slide down when entering, and that keeps the volume of the polishing tank and the polishing tank operating space a considerable amount while keeping the center of gravity of the machine body low. The purpose is to

[0011]

As has been conventionally seen, a revolution plate fixed to a revolution main shaft, a plurality of rotation shafts provided perpendicularly to the revolution plate, and rotatably supported by the rotation shafts. And a polishing tank having an abrasive material and an abrasive material inlet / outlet hole, and a polishing tank lid that is openably / closably fitted to the inlet / outlet hole,
And a control mechanism for rotating the polishing tank in a direction opposite to the rotation direction of the revolution plate during polishing and for making both rotation cycles the same, the polishing tank being rotatably cantilevered by a rotation shaft on one end face, and the other. In an automatic high-speed centrifugal barrel polishing machine in which the end face of the polishing object and an abrasive material inlet / outlet hole are formed, the automatic high-speed centrifugal barrel polishing machine according to the present invention is a supporting mechanism for supporting both sides of the polishing tank during polishing. One support mechanism is composed of the above-mentioned rotation shaft, and the other support mechanism is composed of a polishing tank lid fitted in the polishing tank and an arm body fixed to the revolving main shaft, and the above-mentioned polishing body is carried out by the arm body. The tank lid is rotatably supported by a cantilever.

Further, a self-aligning bearing is provided at a connecting portion that rotatably holds the polishing tank lid, and a fitting frame for both is formed at a peripheral portion of the polishing tank or the polishing tank lid. There is. An arm supporting the polishing tank lid is slidably mounted in the cylinder mounting seat fixed to the revolution spindle, a fluid cylinder pivotally supported by the mounting seat and provided with a fluid transfer mechanism, and the cylinder. A piston and an arm whose end is fixed to the polishing tank lid support mechanism, and the arm is rotatably supported by a rod of the piston and a washer fixedly mounted on the revolution main shaft.

In the automatic control of the arm body, a publicly known technique is newly applied to the relevant field, and the fluid transfer mechanism is fitted with a fluid storage mechanism equipped with a flow rate control device and the revolution spindle end number. A can body in which a number of circular fluid carrying grooves are engraved, a fluid blocking material interposed between the fluid carrying grooves and interposed between the can body and the revolution spindle, the can body and the fluid storage mechanism. A first fluid carrying pipe interposed between the can body and the cylinder, and a second number corresponding to the number of cylinders interposed between the can body and the cylinder.
The first fluid inlet / outlet hole formed in the fluid transport groove of the can body and the second fluid inlet / outlet hole provided in the end of the revolution spindle are the same, which are constituted by a fluid transport pipe. And the second fluid carrying pipe having the second fluid inlet / outlet hole as the starting end is embedded in the revolution spindle.

Further, in the automatic high speed centrifugal barrel polishing machine according to the present invention, all of the polishing tank, the polishing tank lid, the revolving spindle, the rotating shaft and the supporting mechanism for supporting them, and their driving mechanism and their controlling mechanism are all provided. It is enclosed in a casing, and an abrasive material and an abrasive transporting hole are formed on the end surface of the casing on the side of the polishing tank lid, and the casing is rotatably supported by a support seat having an angle fixing mechanism. .

Structurally, there is provided a mechanism in which the casing is fixed horizontally during polishing, and the casing is inclined and fixed inside and outside the inclination angle of 45 ° ± 15 ° when carrying in / out the abrasive and the abrasive.

A casing auxiliary support seat extends from at least one position in the direction of the revolution main axis from the casing support seat, and a casing fixing mechanism corresponding to the angle fixed by the casing support seat is used as the casing auxiliary support seat or the casing auxiliary support seat. It is provided in the casing or both.

[0017]

With the above-mentioned structure, each polishing tank is provided with a rotation shaft provided on the revolution plate perpendicular to the revolution plate and an arm body fixed to the revolution main shaft during polishing, that is, when the opening of the polishing tank is closed. Is rotatably supported by a polishing tank lid which is rotatably supported by a polishing tank lid. In other words, when the polishing tank lid is opened, each polishing tank is supported on one side by the rotation axis, but when the polishing tank lid is closed, the rotation axis which is the fixed support mechanism and the polishing tank lid which is the other support mechanism are supported. And the arms support both sides. Therefore, even if a large centrifugal force is generated due to the high speed rotation of the polishing tank, the problem of the vibration and the instability caused by the vibration during the one-sided support can be avoided.

Since the coupling device for rotatably supporting the polishing tank lid on the arm body is provided with the self-aligning bearing, when the same mechanism is installed at the center of the polishing tank lid, Even when the lower end surface of the bath has a slight inclination, the pressing force of the arm body applied to the center of the polishing bath lid ensures that the adhesion between the polishing bath and the polishing bath lid is so strong that even a slight gap does not occur.

Moreover, due to the presence of the fitting frame formed between the polishing tank and the peripheral portion of the polishing tank lid, once the two are fitted, there is no discrepancy due to shock or vibration at the joint surface, and there is no fitting between them. Since the adhesion is maintained firmly, the rotation support of the polishing tank during polishing is also stable.

A fluid, which is a typical example of oil, is poured into and carried out from a fluid cylinder which constitutes an arm supporting the polishing tank lid, and a change in fluid pressure accompanying this is controlled by automatic opening / closing of the polishing tank lid. It becomes a means.

When the polishing tank lid is opened, the fluid is carried into the cylinder bottom chamber separated by the piston of the fluid cylinder, and the fluid volume and the fluid pressure in the chamber increase, and at the same time, the piston rod side of the fluid cylinder. The fluid is discharged from the chamber, and the fluid volume and the fluid pressure in the chamber decrease. As a result, the piston slidably mounted in the cylinder is pushed up in the opposite direction from the cylinder bottom, and as a result, the end is pivotally attached to the rod end of the piston and the washer fixed to the revolution main shaft. The arm pushes up the other end of the arm supporting the polishing tank lid with the pivot of the washer as a fulcrum, and this operation effect opens the polishing tank lid.

On the contrary, when the polishing tank lid is closed, the fluid is carried out from the cylinder bottom chamber separated by the piston of the fluid cylinder, and the fluid volume and fluid pressure in the chamber are reduced, and at the same time, the piston rod of the fluid cylinder. The fluid is carried into the side chamber, and the fluid volume and the fluid pressure inside the chamber increase.
As a result, the piston slidably mounted in the cylinder is pushed down toward the bottom of the cylinder, and as a result, the arm whose end is pivotally attached to the rod end of the piston and the washer fixedly mounted on the revolution spindle. , The other end supporting the polishing tank lid is pulled down around the pivot with the washer as a fulcrum, and the polishing tank lid is closed by this operation effect.

Since the fluid cylinder is pivotally supported by the cylinder mounting seat fixed to the revolution spindle, the fluid cylinder rotates together with the revolution spindle. Each member linked to the cylinder, that is,
Similarly, each member that constitutes the arm that supports the polishing tank lid rotates together with the revolution spindle.

The fluid supplied to and discharged from the fluid cylinder is provided with a fluid storage mechanism equipped with a flow rate control device and a circular fluid carrying groove, which is fitted to the end of the revolving spindle and has a number corresponding to the number of cylinders. Between the can body, the first fluid carrying pipe interposed between the can body and the fluid storage mechanism, and the second fluid carrying pipe interposed between the can body and the cylinder in a number corresponding to the number of cylinders. To reflux.

Since the second fluid carrying pipe having the piston as the starting end is embedded in the revolution main shaft through the second fluid inlet / outlet hole which is the other end, the casing at the second fluid carrying pipe embedding part of the revolution main shaft. It is possible to be supported by rotation.

Further, since the presence of the buried portion enables the fluid to flow into and out of the circular fluid carrying groove in the can regardless of whether the fluid is stationary or rotating in the revolution spindle.
The fluid in the circular fluid carrying groove flows through the first fluid inlet / outlet hole provided in the carrying groove and flows back to the first fluid carrying pipe.

The above-mentioned four parts connected to each other, that is, the liquid storage mechanism, the fluid carrying groove, the first fluid carrying tube, and the second fluid carrying tube are installed between the fluid carrying grooves, and the can body and the revolution spindle are installed. The fluid blocking material interposed between and prevents fluid leakage between the circular fluid carrying grooves inside the can body regardless of whether the revolution spindle is rotating or stationary. The fluid system constituted by the cylinder connected to the above is an independent fluid system and can be controlled separately. Therefore, when opening and closing the polishing tank lid, it is possible to perform optional control for each polishing tank lid or for opening or closing several tanks or all tanks simultaneously depending on the control setting status of the flow rate control device and the operating procedure based on the control setting status.

The polishing tank, the polishing tank lid, the revolving main shaft, the rotating shaft, and the supporting mechanism for supporting them, and the driving mechanism and their controlling mechanism, are the main parts of the machine body of the automatic high-speed centrifugal barrel polishing machine according to the present invention. Make up. Since the main part of the fuselage is enclosed in a casing, and the casing is rotatably supported by a support seat provided with an angle fixing mechanism, the angle setting of the casing is performed using the angle fixing mechanism. By doing so, the angle of the main part of the machine body, which changes in accordance with the change in the angle of the casing, is set, and as a result, the angle of the polishing tank is set.

When starting the polishing step, first, the angle of the casing is set so that the end surface of the polishing tank where the polishing tank lid is installed faces the set elevation angle, and the polishing tank lid is opened under such a condition. Cover the abrasive and abrasive through the abrasive and abrasive conveying holes formed in the casing,
From the opening end of the polishing tank, slide the inner side surface of the polishing tank with the set elevation angle down and carry it in.

At the time of polishing, it is usual to set the angle of the casing so that the polishing tank is horizontal and fix the casing. However, the polishing efficiency, the characteristics of the polishing material and the polishing material, the progress of polishing, etc. Accordingly, the angle of the casing can be appropriately set to a different angle and fixed.

When the polishing step is completed and the polishing object and the polishing material are carried out from the polishing tank, the angle of the casing is set so that the polishing tank end surface on which the polishing tank lid is installed faces the set depression direction. Under such a condition, first, the rotation of the polishing tank is stopped to open the polishing tank lid, and then the polishing object and the polishing material are slid down on the inner side surface of the polishing tank with the depression angle, and the above-mentioned opening end surface is used to It is carried out to the next process position such as a sorter through the abrasive material and the abrasive material conveying hole formed in the casing. The same procedure is repeated in each polishing tank by rotating the orbital plate in a rotating manner.

When the casing is set at a horizontal angle during polishing, the polishing efficiency is the best, and when loading and unloading the polishing material and the polishing material from the viewpoint of slippage and preventing damage to the polishing material. It is clear from experience that the optimum angle for elevation and depression is 45 ° ± 15 °, although a difference can be seen depending on the characteristics of the abrasive and the abrasive.

Since the casing is rotatably supported and can be fixed at an angle, it is not necessary to install the sorter immediately below the polishing tank contents carry-out hole. The height of the operating space of the polishing tank from the base of the machine can be reduced to a considerable extent by disposing the selector at a position directly below the polishing tank contents unloading hole. In this way, the center of gravity of the entire machine body can be set downward, and the machine body is remarkably stable even during polishing. As a result, a considerable amount of space can be allocated to the polishing tank operating space.

As for the accessory mechanism such as the stocker and bucket, and the polishing material carry-in mechanism, the system of equipment can be installed separately from the main body part of the machine covered by the casing, so that there is room for the accessory mechanism. Spatial allocation becomes possible.

The one-point support by the casing support seat is
During polishing, the barrel tank is rotated to cause large vibrations in the entire machine body. However, by extending at least one casing auxiliary supporting seat in the direction of the revolution main axis, the casing serves as a multi-point support, and vibration during operation is greatly reduced.

Further, due to the extension of the casing auxiliary support seat, even if a barrel tank having a long tank length is installed in the revolution main axis direction, vibration of the machine body during operation is suppressed, so that the barrel tank having a long tank length is suppressed. It also has a structural effect that opens the way to the production of larger barrel polishing machines equipped with.

Second revolution plate 5b, revolution chain 6, rotation bearing case 7, rotation bearing 8, revolution V pulley 9, rotation sprocket 10, rotation sprocket chain 1
0b, tension maintaining chain gear 10c, barrel tank shaft 11,
Revolving main shaft 12, revolving bearing 13, revolving bearing case 14, stop revolving sprocket 15, revolving plate holding shaft 18, revolving bearing case 19, and revolving bearing 20. In the support mechanism, the rotation and revolution of the barrel tank 22 are separately controlled by the control of the drive source worm speed reducer 3, and the barrel tank 22 is rotated in the opposite direction to the rotation direction of the revolution plates 5a and 5b during polishing. , For the mechanism of action that controls the rotation cycle of both to be the same,
Since the technique is well known or well known in the art, the description thereof will be omitted.

The barrel tank shaft 11 is opened when the barrel tank lid 34 is opened.
Thus, the barrel tank 22 supported on one side is supported on both sides during polishing or when closing the opening of the barrel tank. At the time of polishing, the barrel tank lid 34 is pressed against the barrel tank 22 by the arm body composed of the washer 36 serving as the arm base point, the arm 24, the bearing case 25, and the bearing 27. As a result, the arm body and the barrel tank lid 34 function as the other rotating support of the barrel tank 22.

Therefore, the large centrifugal force caused by the high speed rotation of the barrel tank, the vibration of the barrel tank 22 caused by the centrifugal force, and the instability of the airframe due to this vibration are caused by the one-sided support. It is significantly reduced compared to the case.

Since the shaft body 26, the bearing 27, and the bearing case 25 are self-aligning mechanisms, when pressure is applied to the barrel tank 22 from the center of the barrel tank lid 34 on which the shaft body 26 is installed, the barrel tank 22 is barreled. Even when the opening of the tank 22 is not completely perpendicular to the barrel tank center line, the barrel tank lid 3
It is possible to press the 4 into close contact with the opening of the barrel tank 22.

The inside of the barrel tank 22 including the opening,
Since the barrel tank opening abutting surface of the barrel tank lid 34 is coated with the rubber riding 21, the degree of adhesion becomes strong before the barrel tank opening is closed, even if a slight gap does not occur. The inside of the barrel tank is sealed.

In this embodiment, since the fitting frame 34a and the cage structure are formed on the peripheral edge of the barrel tank lid 34, once the barrel tank lid 34 is pressed and fitted into the barrel tank, the barrel tank center line is formed. Without the barrel tank lid 34 sliding in the direction,
There is no problem of discrepancies between the both surfaces due to shock or vibration that may occur during polishing.

As described above, since the barrel tank lid, which has a high degree of adhesion and a high degree of fit when the opening of the barrel tank is closed, is used as the rotation supporting mechanism during polishing, the rotation supporting function of the barrel tank is extremely stable. Has become.

In the arm supporting the polishing tank lid, which is composed of four members, that is, the cylinder mounting seat 23d, the barrel tank lid opening / closing fluid cylinder 23a, the piston 23b and the piston rod 23c, and the horseshoe-shaped arm 24 in side cross section, 23b and piston rod 23c slide,
This is an effect produced by a change in the amount of fluid in the α chamber and the β chamber in the barrel tank lid opening / closing fluid cylinder 23a.

The amount of fluid in the cylinder 23a is constant. Therefore, an increase in the amount of fluid in the α chamber causes a decrease in the amount of fluid in the β chamber and the opening of the barrel tank lid 34, whereas a decrease in the amount of fluid in the α chamber causes an increase in the fluid amount of the β chamber and closing of the barrel tank lid 34. Occur.

Α in the fluid cylinder 23a for opening and closing the barrel lid
When the fluid is injected into the chamber and the fluid in the β chamber is carried out at the same time,
The piston 23b and the piston rod 23c are pushed in the direction of the piston rod, and the piston rod 23c
By pushing the horseshoe proboscis of the horseshoe-shaped arm 24 of side section pivotally attached to the piston rod in the same direction as the piston rod, the horseshoe horseshoe of the horseshoe-shaped arm 24 of side section is used as a base point. To lift the neck of the arm 24,
The barrel tank lid bearing case 25 fixed to the neck end of the horseshoe-shaped arm 24 of the side cross-section also works together, and the barrel tank lid is lifted to open the barrel tank end face opening.

On the contrary, the fluid cylinder 23 for opening and closing the barrel tank lid
When the fluid is carried out from the α chamber in the a and the fluid is injected into the β chamber at the same time, the piston 23b and the piston rod 23
c is pulled back in the direction of the piston rod, and this is provided at the top of the horseshoe-shaped arm 24 of side section by pulling back the horseshoe proboscis of the horseshoe-shaped arm 24 of side section pivotally attached to the piston rod 23c in the same direction as the piston rod. Axis 3
Since the neck portion of the horseshoe-shaped arm 24 having a side cross section is swung with the base 6a as a base point, the barrel tank lid bearing case 25 fixed to the neck end of the horseshoe arm 24 having a side section also cooperates to form a barrel tank lid. 34 is pulled back from the position of the barrel tank lid 28 when the lid is opened as shown by the broken line in FIG. 1, and the end surface of the barrel tank is closed.

When the barrel tank lid is opened / closed, the pivot 35 provided between the piston rod 23c and the arm 24 smoothly interlocks the two pivotally connected to each other so that the arm 24 can be properly moved up and down. Adjust to something.

Fluid storage mechanism C equipped with the above flow rate control device
And the two closed chambers formed in the barrel tank lid opening / closing fluid cylinder 23a, that is, the α chamber which is the cylinder bottom side chamber and the β chamber which is the piston rod 23c side chamber have the same fluid path form.

Regarding the α-chamber connecting path, the flow paths are as follows.

First, when the barrel tank lid 34 is opened,
The fluid carried out from the fluid storage mechanism C provided with the fluid control device passes through the first fluid transfer pipe 37 a interposed between the fluid storage mechanism C and the can body 31, and is passed through the first fluid carrier pipe 37 a. It is transported to the first fluid inlet / outlet hole 32a of the one fluid inlet / outlet hole. The fluid that has passed through the first fluid inlet / outlet hole 32a has a circular fluid transport mechanism 3 engraved in the inside of the can body 31.
It is transported to 1a.

After that, the fluid passes through the second fluid inlet / outlet hole 33a formed in the revolution main shaft 12 and is transported to the second fluid transport pipe 38a connected thereto. Second fluid transfer hole 3
3a and the first fluid transfer hole 32a correspond to the fluid transfer groove 31.
Since they meet at a, the fluid flow path is not interrupted regardless of whether the revolution spindle 12 is rotating or stationary.

In this way, the fluid passing through the second fluid transfer pipe 38a is injected into the α chamber in the barrel tank lid opening / closing fluid cylinder 23a to which it is connected.

On the contrary, at the time of closing operation of the barrel tank lid 34, the fluid is carried out from the α chamber in the barrel opening / closing fluid cylinder 23a, and the carried-out fluid now flows backward through the second fluid carrying pipe 38a. , To the second fluid transfer hole 33a.
Then, the fluid flows backward through the same path as described above and returns to the fluid storage mechanism C equipped with the fluid control device again.

The β-chamber connecting route is similar to the α-chamber connecting route, and its flow paths are as follows.

First, at the time of closing the barrel tank lid 34,
The fluid carried out from the fluid storage mechanism C provided with the fluid control device passes through the first fluid transfer pipe 37b interposed between the fluid storage mechanism C and the can body 31, and is passed through the first body carried by the can body 31. It is transported to the first fluid inlet / outlet hole 32b of the one fluid inlet / outlet hole. The fluid that has passed through the first fluid inlet / outlet hole 32b is inside the can body 31 and is formed in the circular fluid carrying groove 31.
It is transported to b.

After that, the fluid passes through the second fluid inlet / outlet hole 33b formed in the revolution main shaft 12 and is transported to the second fluid transport pipe 38b connected thereto. Second fluid transfer hole 3
3b and the first fluid transfer hole 32b correspond to the fluid transfer groove 31 described above.
Since they are associated with each other at b, the fluid flow path is not interrupted regardless of whether the revolution main shaft 12 is rotating or stationary.

In this way, the fluid passing through the second fluid carrying pipe 38b is injected into the α chamber in the barrel tank lid opening / closing fluid cylinder 23a to which it is connected.

On the contrary, when the lid of the barrel tank lid 34 is opened, the fluid is carried out from the α chamber in the fluid tank 23a for opening and closing the barrel tank lid, and the carried-out fluid this time flows through the second fluid carrying pipe 38b. It flows backward and is transported to the second fluid transport hole 33b. Then, the fluid flows backward through the same path as described above and returns to the fluid storage mechanism C equipped with the fluid control device again.

At the ridges of the circular fluid transfer holes 31a and 31b arranged in a row in the can body 31, an O-ring O provided between the can body 31 and the revolution main shaft 12 causes the can body 31 to move. Inside, leakage of fluid between the circular fluid carrying grooves is prevented. As a result, the fluid control flow path is independent for each barrel tank, and is subject to independent control by the fluid storage mechanism C including the fluid control device. Therefore, control or setting of the fluid storage mechanism C including the fluid control device is performed. If the functions are adjusted, it is possible to perform optional control for opening / closing barrel tank lids for each tank, several tanks simultaneously, or all tanks simultaneously.

FIG. 7 is a schematic side perspective view of the automatic high-speed centrifugal barrel polishing machine of this embodiment when the main body is tilted up or when an abrasive and an abrasive are carried in. FIG. 8 is an automatic high-speed centrifugal barrel polishing machine of this embodiment. 3 is a schematic side perspective view of the main body when the main body is tilted down, or when the abrasive and the abrasive are carried out.

In the automatic high-speed centrifugal barrel polishing machine of this embodiment, the main body portion is enclosed by the main body case 17, and the main body case 17 is rotatably supported by the main body case support seat 40. Figure 7 shows the entire body
And as shown in FIG. 8, it becomes a tilting type. The angle control for elevation and depression of the machine body is fixed at the speed reducer 40a for tilting the machine body.
Done by.

When carrying the polishing material and the polishing material into the barrel tank 22, as shown in FIG. 7, the body of the machine is tilted upward, the polishing tank lid 34 is opened, and the stocker and the stocker are provided separately from the machine body. An abrasive material and an abrasive material are introduced from an abrasive tank content introducing device T equipped with a bucket and the like through a polishing content transfer hole 39 formed in the main body case 17. At this time, if the system for linking the revolution spindle and the rotation axis drive control mechanism described above is set, the process of introducing the contents of the polishing tank becomes smoother.

At the time of carrying out the polishing material and the polishing material from the barrel tank 22, as shown in FIG. 8, the body of the machine body is tilted downward, and first, the rotation of the barrel tank 22 is stopped. Next, the polishing tank lid 34 is opened, and the contents of the polishing tank are slid toward the selector S provided separately from the machine body at a position below the opening of the barrel tank and where the contents of the barrel tank can be received. The contents are passed through the polishing contents transfer hole 39 formed in the main body case 17,
Land on the sorter S. This step is performed by the revolution plate 5a,
5b is rotated and stopped in a rotating manner, and the number of barrel tanks 22 mounted is repeated.

The sorting machine S does not need to be installed directly below the barrel tank 22 that directly covers it. If the barrel tank is tilted to the lower limit angle and installed at the sliding position of the contents of the barrel tank, the center of gravity of the tilting machine body can be suppressed to a much lower level as compared with the case where the barrel tank is upright or directly covered.

Further, if the above-described revolution spindle and rotation axis drive control mechanism and the related system setting are performed in the same manner as in the polishing tank content feeding device T, the polishing tank content unloading and sorting processes are organically combined to make the operation smoother. Become.

As described above, since the polishing tank contents feeding device T and the sorting device S are provided separately from the machine body, the automatic high-speed centrifugal barrel polishing machine has a structure with a space in terms of equipment. There is.

During polishing, the angle is usually set so that the body of the machine is horizontal. However, depending on the polishing efficiency, the characteristics of the polishing object and the polishing material, and the progress of polishing, if the main body tilting reduction gear 40a is used and the lock pin and limit switch system described later are additionally installed, the body of the machine can be adjusted to a different angle as appropriate. It is also possible to set and fix the angle of.

The tilt angle of the machine body is different depending on the characteristics of the polishing material and the polishing material from the viewpoints of the slip-down degree and the damage prevention of the polishing material.
It is clear from the experience in the industry that the sliding content of the polishing contents is optimally 45 ° ± 15 ° both inside and outside when it is carried out.
Further, such limit angle setting can be easily realized by the limit switch mechanism described later.

A main body case auxiliary support seat 41 extending in the direction of the revolution main axis from the main body case support seat 40 provides a two-point support for the main body case that encloses the main body of the machine, and supports the main body case particularly during polishing. Compared with the case of single-point support by the seat 40, the airframe becomes much more stable.

3 installed on the main case auxiliary support seat 41
In the present embodiment, it is possible to set the angle at three points, that is, an elevation angle of 45 degrees when tilted upward, a horizontal angle, and a depression angle of 45 degrees when tilted downward, by means of limit switches at some positions. At the time of setting these angles, the lock pin 43a installed on the main body case auxiliary support seat 41
Is fitted into the lock pin fitting hole 43b formed in the surface of the main body case 17 by using the lock pin retracting / controlling device 42 by fluid control, whereby the main body case 1
7 is more firmly fixed at two points of the main body case support seat 40 and the lock pin and the lock pin fitting hole.

In order to release the fixed angle of the case body 17, the lock pin retracting control device 42 by the above fluid may be used to lift and retract the lock pin 43a in the lock pin guide metal 44.

Upper limit off, horizontal position off, lower limit o
The limit switches for ff and attached at three places serve as automatic angle control fixing means for the case main body support seat 40 and the case main body auxiliary support seat 41 extended to this.

Upper limit off, horizontal position off, lower limit o
Limit switches 47a, 47b, 47c for ff
The switch-off state is obtained when the round-seat-fitting portions constituting these switches are fitted to the round seats for the upper limit off, the horizontal position off, and the lower limit off, which are respectively provided on the surface of the main body case 17. The drive of the main body tilting reduction gear provided on the main body case support seat 40 for tilting drive is stopped, and the angle of the main body is fixed.

Although not described in this embodiment, when the multi-point support is carried out in the revolution main axis direction as well as the two-point support as in the present embodiment, the tank length is increased in the revolution main axis direction. Even if a long barrel tank is mounted, mechanical inconvenience will rarely occur, and stability of the machine body during polishing will not be impaired. Therefore, a so-called large-sized automatic high-speed centrifugal barrel polishing machine equipped with such a long barrel tank can be sufficiently manufactured as an embodiment.
