Description

[Detailed description of the invention] The present invention relates to a two-member centering attachment/detachment device.

Recently, welding robots, painting robots, and other industrial robots have become popular, and their mechanical power can be used to weld various workpieces, as well as paint, solder,
Various operations such as parts assembly and press processing are being carried out.

Now, to take a typical welding operation as an example, we introduce a specialized welding robot that is suitable for a specific workpiece.
In the case of large-leaf production of a small number of products, the robot installed and fixed on the work floor can also be used as a welding jig table device for peripheral equipment that carries in and out the workpiece, and is suitable only for the small number of products. It is sufficient to adopt a special structure and function for exclusive use, and this can improve work efficiency, and even if it is quite expensive as a special order item, it is profitable in mass production of the work. Also fits.

However, small and medium-sized enterprises, which are the bases for large companies that mass-produce large products, have to produce a wide variety of assembled parts in small quantities or in the middle of the industry in response to frequent model changes of the large products, and they are also complex. It is often necessary to weld parts with long welding lines so as not to interfere with the appearance of the parts, and the quality and precision of the finished product must be extremely high. In response to such demands, it is clearly disadvantageous in terms of work efficiency and profitability to introduce the above-mentioned dedicated welding port; Although there are practical reasons why flexible welding robots are highly sought after, the operating rate of such general-purpose welding robots is still not high. Even assuming that the robot itself has excellent versatility, the jig table device that works in conjunction with the robot to load and unload workpieces must be capable of responding to changes in the variety of workpieces. This is because if flexibility were the key, the result would be the same, and the robot's operating rate would not be the same.

The versatility or flexibility of the jig table device related to peripheral equipment means that, depending on the variety of workpieces, the customer's jig table for workpiece clamping can be carried into the robot,
This means that it can be interchangeably attached to and detached from the carry-out slide board.

Furthermore, in this case, once the two members are installed, it is necessary to maintain the two members, the table and the slide plate, in a secure and stable fixed state, and to obtain excellent centering position accuracy. Otherwise, the welding position will be out of order due to the movement of the robot, and a high-precision finish and high quality cannot be obtained. Furthermore, the structure of the attachment/detachment device must be such that the VC is simplified for easy maintenance and inspection, and anyone can perform the so-called one-touch attachment/detachment operation with high efficiency. This kind of work is not limited to welding work by the robot mentioned above, but also includes painting, soldering, fusing, parts assembly, etc.
The same can be said about press working and other operations.

The present invention aims to provide a two-member centering attachment/detachment device that meets these demands, and its specific configuration will be described in detail below based on the illustrated embodiment. That is, the figure shows a general-purpose arc welding robot as a representative industrial robot, and illustrates the present invention applied to a welding jig table device as a peripheral device. In Figures 1 to 11, (1) is a leg stand that is installed on the work floor, and the frame is made of square timbers at the left end to form a rigid rectangular parallelepiped shape. (2) is a pair of left and right slide guide rails laid on the top surface of the foot stand (11), which extend parallel to each other along the longitudinal direction (front-back direction) of the foot stand i11. At a mutually intermediate position, a slide drive unit integrated with the leg stand (I+) is used to drive a slide plate for transporting the workpiece (described later) to reciprocate along the rail +21, and to move the slide plate on the jig table. It functions to carry the workpiece into and out of the action area of the welding robot (R1).In this respect, the drive unit (3) is not shown in detail, but as a differential piston type rotary actuator total drive source, Through air pressure, its mounting base (4)
It relates to a slide cylinder form in which a pair of guide shafts (5) are γd and linearly reciprocated. However, as long as the above-mentioned sex-sliding effect can be performed, hydraulic pressure, electric motor, or other driving means may be used instead of pneumatic pressure.

(61 is a pair of left and right air cylinders attached to one end in the longitudinal direction (the rear end where the workpiece is taken out) of the leg stand (1), and the piston rod (the screw tip of the A cap tube (9) with an overhanging stopper flange (8) is screwed onto the holder, and is fixed to the lock nut (10).By turning the nut (10), the cap tube (9) is attached to the screw tip. 9) can be adjusted.This air cylinder (6) is used for the return movement of the workpieces that have been welded to the rear of the slide plate or jig table, so that the welding robot (Jl) Katana) et al. 2.3
When it is carried out as shown in the figure, it acts to push up the lifting platform (see Figures 7 to 9), which will be described later.
Alternatively, a hydraulic cylinder or other lifting actuation means may be used.

In this regard, in the figure, the angle stay (11) is welded to the side of the installation foot (1), the mounting flange (I2) of the air cylinder (6) is connected to the side of the installation leg (1), and a plurality of bolts ( 1 and nuts θ4), but the mounting and fixing means are not limited to this.Also, the pair of cylinders (6) are fixed in relation to planar forms such as slide boards, lifting boards, and jig tables. , as if they were facing each other diagonally on a rectangular slide board (3rd.
(see Fig. 6), although they are fixedly installed on the pedestal il+, it goes without saying that the arrangement is not limited to this arrangement.

A slide plate (15) for transporting the workpiece is fixedly installed on the mounting base (4) of the drive unit (3) so as to reciprocate at the same pace as the drive unit (4). It is almost square in shape. (1→ is the slide board (
The plurality of rail supports fixed to the lower surface of I5) are seats,
As is clear from Fig. 4.8, its groove shape allows it to slide freely into the rail (2) on the pedestal (+1).(lη is also set on the top surface of the slide board (15) The stopper flange (1 barrel) that protrudes near the head of the lifting guide pins positions and regulates the lifting limit of the lifting board (described later). In the figure, the guide pin + 17)' e slide board ( 15) from above, but other methods can be used as the means for attaching and fixing.

(19) is a jig table fixedly attached to the slide plate tl[i)k so as to be detachable and replaceable, and may also be called a jig pallet. Although the details are not shown in the drawings, this device is equipped with a bath fitting jig suitable for the workpiece in advance, and the workpiece is detachably set or clamped by this jig. In the present invention, various jig tables with welding jigs corresponding to the different shapes of the workpieces are used for replacement in advance due to the production of a wide variety of workpieces and a small number of workpieces. The jig table (19) is interchangeably attached to the slide plate (16) by an attachment/detachment device which will be described in detail later, and is used for automatic welding of the workpiece.

Lifting board +20) is a δ ride board (16) and jig table (
19), and its table 0
In order to smoothly move up and down without interfering with the attachment/detachment device (9), a relief opening (2Il) is provided in the center of the approximately rectangular shape when viewed from the plane. (See Figure 3.6) ) Cz4 is a plurality of eject bins set up on the upper surface of the elevating plate shi0), and corresponds to the pin ejection holes (c) opened through the jig table (19). In other words, as the lift g(5)) rises, the eject bin (4) passes through the jig table, and the welding jig on the table (19) passes through, as is clear from FIGS. 7 to 9. The welded work piece is slightly pushed up from the welding bin, making it easier to remove it.The eject bin (2) is
The bottle (3) is freely inserted and removable into the grooves dotted on the top surface of the lift plate (0), and therefore the bottle (3) itself can be replaced and replaced in another groove. You can do it freely. Such an eject bin (22 and its ejection hole A)
In addition, the number and arrangement of the workpieces are appropriately determined in response to various changes in the workpiece. (2) is a lift board (c)
The double-broken guide bin holder with 9 penetration holes is a hole, and the above-mentioned elevating guide bin (I7) of the slide board (15)
), it acts to guide the elevator plate (tjO) to move up and down correctly and smoothly. Through the fitting state of the guide bin (1) and its receiving hole iX!41, the elevator board (a) is always assembled to the slide board (1 It is also possible to reciprocate as a unit.

Further, the tracks are a pair of left and right positioning stoppers fixed to the lower surface of the elevator platen, and are arranged to correspond to the air cylinders (6) of the installation platform fi+.
As is clear from FIG. 10, the piston rod (7) is releasably engaged with the cap cylinder (9). In other words, when the jig table (19) is unloading the workpiece to the welding robot sail), the sono stopper (2e and cap The cylinder (9) is engaged with the cylinder (9), and when the cylinder (9) is in a stopped state, the air cylinder (6) is activated and the lifting plate (a) is pushed up as shown in Figs. (1! table (1)
9) Push the welded workpiece up from the jig above.

And, conversely, when carrying the workpiece to R1, slide the elevator plate (A) as shown in Figure 5.6.
(The lock between the stopper (251) and the cap tube (9) is released in order to allow the slide movement to move integrally with the plate. The robot returns to the lower position, and the workpiece for the next welding is prepared for mounting on the jig table (19) without any problems.Then, by the forward movement of the slide plate (15), the welding robot (fnl) is transported to the welding robot (fnl). It will be done.

In the figure, the above stopper (C) is used as the slide direction fc of the rising I4 board (4) when viewed from the bottom. a The other end (
The floor plate is formed into a groove-like or horseshoe-like shape with an open rear side (see Fig. 11), and this is connected to a plurality of bolts (
A) is fixed to the bottom of the lifting board (A). η is a receiving stepped portion provided on the inner wall surface of the concave groove for the cap cylinder (9), and is removably engaged with the stopper flange (8) protruding from the cap mN91 of the piston rod (7). Therefore, move the elevator board (A) to the air cylinder (6)! It can be lowered aggressively and quickly, and its work efficiency is excellent. Cap tube (9) at the screw tip of the piston rod (7)
However, the figure suggests that the stopper □□□ protrudes so as to always block the slide path of the lifting platform, and that the positioning stopper is correctly faced.

This type of welding jig table device is attached to the welding robot (R1) as a pair of parallel configurations as shown in Fig. 1.
R9) The work clamped on the installation leg
A slide board (
Depending on the country, the welding robot (fR) is kept in a state where it moves forward (see Figure 5.6) and a state where it moves backward (see Figure 2.3). At the second stop position, automatic welding is safely performed, and at the second stop position, the welded workpieces are removed and preparations are made for mounting the workpieces for next welding.

As mentioned earlier, the self-elevating platen is moved upward as shown in Figures 7 to 9 when it is removed, and that the elevating plate (fA) is returned to its lowered position during subsequent welding preparations. That's right.

In that case, as suggested from Fig. 1, the two units of the bath welding jig table device alternately carry out the action described in E to efficiently operate the welding robot sail. The number of installed units, arrangement form, etc. may be other than those shown in the drawings. For example, a plurality of jig stand devices may be installed in a radial arrangement with the welding robot fRi at the center. Since the welding robot (welding robot) 1ltl itself is not a subject of the present invention, it will only be shown schematically in the figure, but it is actually an articulated type with 5 to 6 degrees of freedom, and the installation is not fixed on the work floor. The so-called FTP method is used for its control. In any case, the above-mentioned action of the jig table device is of course electrically controlled so that it is performed automatically in conjunction with the automatic welding action by the bath robot (Fan), and therefore the operator is All you have to do is press a button on the control panel.

The attachment/detachment device for the jig table 09 mentioned above forms an assembly unit, and as shown in Figures 1 to 8, the attachment/detachment device for the table (Jig table 09) is constructed as a pair of 21 fixtures, with the top and bottom facing each other. Intervention is installed.

That is, in the enlarged views of FIGS. 12 to 21 which extract this as a single unit, the nail plate is removably fixed to the lower surface of the jig table (19) with a plurality of bolts 4, and its hanging tip. A circular flange pawl (made of paulownia wood) that extends outward, and the flange pawl (', A has multiple grooves for unlocking that open outward in the middle of the circumferential surface)
is cut out. In the case of the figure, the groove 1311 is -
Although they are arranged as a pair of two facing each other on a straight line, the number may be further increased as long as they are arranged at equal intervals on the flange claws. +32

On the other hand, 641 is the nail plate on the side of the daple (sliding movement 15 opposite to the nail plate on the 1 side), and the slide atu5 ) is solidified on the top surface. η is a bolt that removably fixes the floor plate (G). This claw shape has a cylindrical shape, and its upright tip has a flange claw (
C) and a continuous four-round front 139) are formed directly below it. In that case, the figure suggests that the above-described groove Ill for unlocking does not exist in the flange pawl on the side of the slide plate θ. 14Q is a cylindrical part with a stepped diameter at its claw-shaped center opening, which serves as a spring storage chamber. 0υ is also claw type 134
) is a centering guide post made of bearing steel that is integrally press-fitted from below into the center opening of the post, the lower end of which is preferably shielded by the mounting seat side, and also the centering guide post of the post 0.
The upright upper end of 1) has a claw shape (341) that also protrudes from the upper surface and faces the claw edge of the table-1 rule, and the centering guide bushing 131 can be freely fitted and removed in the protruding part. A ball retainer (6) is fitted onto the outside of the pole retainer.The lace part of the pole retainer is made of synthetic resin, aluminum, copper, brass, etc., and the steel balls are placed so that they can slide freely. (44 groups are embedded and held, and make point contact with the steel guide bush. (441 is a coil spring that constantly applies upward force to the retainer from below, and its elasticity and spiral Together with the directionality, the ball retainer 04 is allowed to move up and down and rotate, thereby smoothing the engagement and disengagement with the table (first side pawl plate 128).
After fitting, the nine springs maintain close contact with the guide bush (331) with high precision.The spring (b) is sealed in the spring storage chamber (inside the state). The holder is a stop plate and is removably fixed by a screw screw screwed into the top surface of the guide post (+41).

In addition, (471 is a hook segment for securing and fixing the claw die on the jig table (19) side and the die plate 1 of slide plate f15), which is made of hardened steel and is attached to the lock mentioned above. Size that fits the release groove 01)
The arrangement is scattered as multiple pieces. The segment 1
471 is a double claw board (flange claw (engraved) at 281%).
The table Q9) has a horizontal U-shaped cross section that is secured from the outside so as to straddle the upper and lower sides of the table Q9). Similarly, the lower end hook 149+ is rotatably fitted into the claw shape (the four circumferential grooves 39 in 5(1)) of the slide plate (I5).

0jO1 is a rotating ring for integrally rotating multiple segments (47).

The segment receptacle cut out in the middle of the inner circumferential surface of the rotating ring (■) is a recessed groove, and the segment 1 is inserted into this recessed groove.
47I is restrained and fixed, so there is a concave groove 1311 for unlocking cut out in the claw shape 4 of table 4+111 and its segment) k? ) can be matched with each other. The handle is an operating handle that comes out from the middle of the polishing process, and is rotated by the operator when removing the slide plate (from the table). + (1) V It is a positioning stopper screw to prevent the free rotation of rotation m (60) when the table (1 audience) is removed. It is pressed by a coil spring (661) enclosed inside the ring.A stopper screw like this is screwed into the middle of the rotating ring, and the ball 161 at its tip allows the slide!+1
5) Frictional resistance is given to the free rotation of the flange pawl (rotation ring because the exposed part is always pressed) on the side pawl type (34i), and this causes the operation position of the operation handle (5g to vary). It is designed to never change.

In the above, the operation handle (to) and the stopper screw (beta) are installed independently, but as long as the above purpose can be achieved, the stopper screw (beta) is installed as shown in Figure 22.23. ) may be enclosed in the operating handle value □□□, and according to this, the handle (fI31 is (J
D. Using the operator, extend the stopper screw (4) and move it forward and backward until the ball (4) and spring (4) are fully rotated.
This can be said to be effective in that it can provide frictional resistance to the rotating ring force (0) without requiring any effort. The symbol - added to both figures is a dowel pin that is driven and fixed at the center of the mounting seat type steel so that it protrudes from the lower surface of the mounting seat type steel, and is attached to the slide plate (16).
When attaching the claw type (341) with multiple bolts, it is useful for facilitating alignment and increasing the parallelism of the attached state between multiple attachment/detachment devices. I. The lower surface of the cutter and the upper surface of the nail stand wi are both polished with high precision, so that the slide plate (15) and jig table (19) can be kept in a correct parallel state with each other. ing.

Figures 12 to 15 show the installation base (slide panel 5 above 11)
This figure shows the fixed lock state of attachment of the jig table 09) to the table (0). In this state, the hook segment (471) fitted and fixed to the rotating ring (c)
19) For the concave groove for unlocking the mold plate (to) in Rule 1)
Therefore, the table (19) is restrained from being pulled out upward from the slide plate (15) by the segment +471 m upper end hook 5 decoy.

Therefore, in order to replace the table (I9) with another one, for example, remove slide u from L151! l) If it hits the soot, its hook segment [Retrospective IO so that η matches the lock release groove (Jl) of the nail holder (c))
is rotated by a fixed rotation angle (θ) from the state shown in FIG. 14 to the state shown in FIG. 16 using the handle pupil. By doing so, the locking action between the upper end hook portion 1481 of the segment (4'7) and the flange claw (T) of the claw stand μs is released, so the table (I9) is attached to the centering guide post (41). This means that it can be completely removed from the slide board (15) as shown in Figures 19-21. FIG. 17 shows, so to speak, the state in the middle of the process. that segment) n7
By aligning the lock release groove (for the lock release groove) on the nail stand end with the nail stand (C) and pushing the nail stand (C) downward along the guide boss (+411), conversely, the table (19) is inserted into the slide board (15). ) of course.

In any case, the nail stand tZa on the table (1g) side and the centering guide post (411) on the slide board (15) side are mutually connected to the centering guide bush (3) fitted and fixed in the center opening of the former. A pole retainer (which can be freely fitted and removed through point contact with the ball decoy of the pole) and a pole retainer (42i is equipped with a coil spring (42
Since the pushing force by the retainer (4) is also applied, it is possible to smooth the upward and downward movement of the retainer (4) and the free rotation of the ball (4). The detachment operation can be performed quickly and efficiently using a so-called one-touch method.In addition, despite its excellent operability, once the table (19) is installed, the centering guide post (41) It is possible to maintain a tightly fitted state between the pole retainer (shino) and the centering guide bushing, and to achieve a highly accurate positioning state that prevents horizontal photography at all, and a completely fixed locking state of the table (19) by the segment (47I). The fact that the guide bush (:+3i), guide post (41), and pole retainer decoy are assembled parts that are of high quality and easy to finish also contributes to achieving this effect.

As suggested from the enlarged view of FIG. 18, the mutual opening width dimension i8+ of the upper and lower end hook portion decoys 191 at Qη (transverse U-shaped hook segment) is rotated to one turn of rotation 4←Q. By setting the tapered shape so that the width gradually becomes narrower as the width increases, rotation of the operating handle 153) in one direction automatically locks the table (19), and vice versa. Rotating table (19)
It is preferable to give each operator instructions on how to unlock the lock. Of course, the rotation angle (θ) of the operating handle 153) can be determined to be the most appropriate constant value depending on the degree of steepness of the inclination angle in the tapered shape.

In the illustrated embodiment, the present invention is applied to a jig stand device as a peripheral device of a welding robot, but it is not limited to such welding work, but can also be applied to painting, soldering, fusing, parts assembly, pressing, etc. The present invention can also be applied to various operations such as processing. In this sense, the jig table (19) and the slide 'Ik (15) are only representative examples of two members that can be attached and detached in the centered state. As for the attachment/detachment device, it can be used interposed between two members that face each other vertically, so to speak, in a vertical installation position, or fixedly installed in a horizontal installation position or tilted at a certain angle. Needless to say, it's worth it.

As described above, the two-member centering release device according to the present invention includes a nail pin μs to be fixed to one member, and a nail holder μs to be fixed to the other member so as to face it. , the flange claws extended correspondingly from the tips of both claw plates (Δ) are extended over the outer circumferential surface of both claw plates ■- so that they can be engaged and fixed to each other at will. N-fitted rotatable hook segment [assembly unit with η] 12k
, and only when the hook segment) t4η is rotated by a certain angle IfL (θ), one claw type 0
48+ can be unlocked upward from the other claw mold (to), and a centering guide post fixed and raised at the center opening of one of the claw molds (c) and the center of the other nail holder. (The centering guide bushing is fitted and fixed to the former, and the ball retainer (four-force pole (c)) is fitted to the outside of the latter. By fitting the pole retainer (6) and applying a pushing force from below by the coil spring at all times, this can be applied to, for example, a jig stand device such as the illustrated embodiment. , it is possible to meet the demands mentioned at the beginning, and it becomes possible to make the jig stand device exhibit versatility and flexibility.

In other words, when the two members are attached, one of the claw shapes e
The flange claw extending from 4 and the flange claw β correspondingly extending from the other claw type (341) are restrained and fixed in a state where they are prevented from being pulled out in the axial direction along the guide post (41) by the hook segment 0η. At the same time, the deflection in the direction perpendicular to that direction is caused by the pole retainer-04.
This is prevented by the close fitting action between the centering guide post (41) and the guide bush (through the hole), resulting in a reliable and stable fixation and extremely excellent centering accuracy. This kind of installation accuracy without backlash is achieved by
On the contrary, it may seem contradictory, as it may cause difficulty in attaching and detaching operations, but in the present invention, the above-mentioned centering guide bush (
A3) and the ball retainer (4"4) are configured to make point contact, and the ball retainer (42) is always given a pushing force from below by a coil spring circle. Therefore, by simply rotating the hook segment 14η by a predetermined angle (θ), the two members can be attached and detached very easily and efficiently.

Furthermore, since the structure of the assembly unit is distinctly simple, and all of its assembly parts are mass-produced products that are of high quality and easy to finish, (4) it can be provided as a product at low cost; It can be said to be a practical invention as it can be mounted and used not only to the jig table (19) and the slide board (16) but also to other two members to be attached and detached using the bolts tzgtaη.
