Description

DETAILED DESCRIPTION OF THE INVENTION The invention in the field of industrial application is to easily repair and polish any number of circular saw blades that have become worn due to use and have poor sharpness, and This invention relates to a circular saw correction and grinding machine that can correct and polish the outer periphery of a saw into a well-balanced shape using the same machine.

Prior Art Conventionally, as shown in Fig. 17, a circular saw a, which has a plurality of cutting edges having an acute angle at the outer circumferential edge C and which are arranged around the circumference at equal intervals, is attached to a rotating shaft d, and a circular saw is used. Agricultural work that efficiently cuts planted grass, stem culms, or other agricultural products using the high-speed rotating action of a saw a is commonly performed and is well known. Due to the collision with the object to be cut, clods of earth, stones, etc., the outer circumferential end C of the cutting edge is worn round within a short period of time, and its sharpness is significantly reduced.

Therefore, when the cutting edge of the round Wa is worn out due to the above-mentioned 5 pas and its sharpness deteriorates, it is necessary to correct and polish the outer peripheral edge C of the cutting edge so that it has the same acute angle shape as the original shape before using it again. I can't.

Therefore, if the cutting edge of the circular saw a is worn round as described above, use a commercially available correction ruler e as shown in Figure 18 (Utility Model Registration No. 34576) to remove the worn circular saw a.
Draw a new shape of a circular saw a' on the surface of which the outer circumferential end C' of the cutting edge b' has an acute angle and the length of the blade is a predetermined size using a scriber f (see button line in Figure 17). Next, the circular saw a was corrected and polished according to the drawing using a grinder K''J, and a regenerated circular saw a' was obtained so that it could be used again.

Therefore, in order to perform the conventional circular saw correction and polishing work, it is necessary to draw a new and accurate circular saw shape using a correction ruler on the worn circular saw surface, which is a tedious work, and to remove the outer periphery of the worn circular saw. Since it is not possible to obtain a circular saw that has been corrected and polished unless it is manually corrected and polished according to the drawing, the work efficiency is significantly reduced, and not only does it take a considerable amount of time for correction and polishing, but it also takes a long time to complete the drawing work. Due to the necessity, considerable skill is required, and the drawn circular saw figures are drawn by hand, perhaps because it is difficult for amateurs to draw them. , increases the degree of wear and tear on the circular saw.

In addition, all of the outer circumferential polishing work is done manually by the worker, making it impossible to finish and polish the circular saw's outer shape to an accurate shape, resulting in the entire circular saw being unbalanced, which can lead to agricultural work. Circular saws sometimes rattle and make abnormal noises, making it impossible to efficiently achieve stable cutting work.In addition, when grinding the blade, the entire blade is ground at once with a grinder, which causes the blade to generate frictional heat. There were disadvantages such as deterioration in quality 2 and extremely poor sharpness.

Therefore, the present inventor has completely abolished the conventional drawing work and manual peripheral polishing work, and has made it possible to adjust the movement of the circular saw in the front and rear directions relative to the fixed grinder, and to move the operating nodle back and forth. The cutting edge of the circular saw is rotated eccentrically by the operation, and the cutting edge of the circular saw is set so that it is fed and rotated in one direction one by one. The back and forth rotation of the operating knife makes it easy to correct and polish the outer periphery of the circular saw to a well-balanced and normal shape, making it easy and efficient for anyone to operate. We have developed a circular saw correction and polishing machine that can easily correct and polish worn circular saws.
This invention was filed as Japanese Patent Application No. 59-102276 (May 21, 1980) and Japanese Patent Application No. 59-177639 (August 27, 1981).

Problems to be Solved by the Invention However, in all of the previously developed circular saw correction and polishing machines, the circular saw rotating body, which is rotated from side to side by the operating handle, is erected on a sliding table. The shaft is mounted on a fixed support shaft, and the mounting shaft to which the one-turn guide plate and the circular saw are attached is suspended on the circular saw rotating body so that it can rotate eccentrically with respect to the support shaft. Therefore, when the circular saw rotating body was rotated back and forth in the left and right directions around the support shaft for cutting edge polishing work and outer periphery correction work, the shaft portion of the support shaft was damaged several hundred times. The repeated rotation operations cause wear and play, making it difficult to accurately rotate the rotary guide plate and circular saw eccentrically with respect to the support shaft, making it difficult to accurately perform blade edge polishing and outer periphery correction polishing. I can't make it happen (
Perhaps the cutting dust generated during the above-mentioned polishing operation may enter the shaft mount between the support shaft and the circular saw rotating body and the sliding surface between the circular saw rotary body and the sliding table, causing damage to the shaft mount. Problems arose, such as accelerating wear and tear and making the rotation of the circular saw rotating body uneven.

Therefore, the present invention eliminates the need for a support shaft that is prone to wear, and instead installs a member in which a circular saw and a mounting shaft equipped with a rotary guide plate are freely rotatably mounted on a rotary plate with a downward-facing flange on the periphery. The rotary plate is fitted and connected to a rotary reference disk provided on a sliding table, so that the rotary plate (1) can be rotated left and right by a predetermined rotational angle along the circumferential wall of the rotary reference disk. Therefore, even if the rotating plate is rotated many times,
If the rotating plate can be rotated by sticking to the circumferential wall of the rotating reference disk, which rattles due to wear, the circular saw and rotating guide plate can always draw an accurate rotation trajectory with respect to the rotating plate. The present invention aims to provide a circular saw correction and polishing machine that can tighten the blade and prevent the entry of cutting dust, and can accurately and smoothly perform blade attachment @ agricultural work and outer circumference correction and polishing work of a circular saw over a long period of time.

+ Step to Solve the Problem Therefore, the technical problem of the present invention is to accurately prevent a circular saw and a rotary plate on which a blowing shaft with a rotary guide plate is installed so that it does not rotate loosely due to wear. To enable rotation, and at the same time, to minimize cutting dust from entering between rotating members, and to always enable smooth rotation to achieve efficient cutting edge work and outer periphery correction polishing work. It is in.

In order to solve this technical problem, we specifically changed the configuration by providing a rotating reference disk on a sliding table that can move back and forth with respect to the grinder, and a circular saw can be removably attached to the rotating reference disk. , and a rotating plate with a flange, which is rotatably supported by a mounting shaft directly connected to a rotating guide plate with a locking part on the periphery, is mounted on the peripheral wall of the rotating reference disk and rotated for a predetermined number of times. This is a 9 m correction polishing machine characterized by a fitted connection so that it can be rotated in the left and right directions by an angle of movement.

Action The technical means described above work like an arrow (see Figures 1 to 16). In other words, the 8-blade circular saw has both the cutting edge and outer cylinder worn out due to cutting of grass, stem culms, or other agricultural products, resulting in a marked decrease in sharpness and an unbalanced peripheral shape of the circular saw. Circular saws such as 4-blade, 3-blade, and 2-blade 21.21', 21", 21'-
In some cases, when the number of blades of the circular saw 21 to be repaired and polished is 8, the grinder 4 is installed at a 45 degree angle and After setting the slider to the X position shown by the solid line in the figure, the entire slide table 8 is moved back to the front as far as possible, and at the same time, the operation knob 1T is rotated so that it collides with the stop position and is stopped at the B position. In addition, a rotary guide plate 19 is directly connected in advance to the rotary plate 11, which is erected in a free-standing manner so that it can rotate freely, and has eight locking portions 20 provided at equal intervals on the periphery. An eight-blade circular saw 21 is attached to @18 via the clamping fitting 24 while adjusting so that the cutting edge 22 of the circular saw 21 and the locking portion 2'0 are aligned.

Next, the sliding length of the sliding table 8 was adjusted by the sliding ivI adjustment device 35 so that the base end of the cutting edge 22 of the circular saw 21 attached to the mounting shaft 18 came into contact with the outer peripheral edge of the stationary grinder 4. After that, the slide table 8 is moved back to the front side completely, and then the grinder 4 is rotated at high speed, and the slide table 8 is reciprocated in the front and back direction by the sliding length.
The cutting edge 22, whose rounded shape 2a has been worn, is reground by the grinder 4 so that it becomes an acute angle.

When the re-polishing work of the single blade of the circular saw 21 is completed by the above-mentioned front-back sliding adjustment operation, move the N-moving base 8 fully backward to the front side again, counterclockwise to return the operating handle 17 from the B position to the A position. Rotate it.

If you do so, you will see a rotating plate 11 with a guard 12 on which a sword 18 is placed upright.
are smoothly rotated in the same direction by the peripheral wall 10 of the rotation reference disk 9.

However, when the operating handle 170 is turned counterclockwise
At the time of starting, the rotation guide plate 19 has a predetermined play interval l between the locking portion 20 and the stopper 28, so that the rotation guide plate 19 is the same as the rotation plate 11 up to the yoke of the play interval l. It is rotated eccentrically in the counterclockwise direction, but -
Once the above-mentioned play distance l range is exceeded, the stopper 28 is locked to the locking portion 20, and the rotation of the rotation guide ff1i9 in the counterclockwise direction is forcibly prevented, so that the rotation guide plate 19 and the circular saw 21 are stopped. are eccentrically rotated about the mounting shaft 18 in the opposite direction to the rotating direction of the rotary plate 11 until the operation handle 17fJ''-A position is rotated, and the supination peripheral end 22a of the circular saw 21 is rotated as the grinder. The operating knob 17 is automatically moved eccentrically so that it matches the set position in step 4 (see Figure 4).Under this condition, turn the operating knob 17 clockwise from position A to position B. When the rotation plate 11 is moved, the rotation plate 11 is attached to the peripheral wall 10 of the rotation reference disk 9 and rotated clockwise by 45 degrees, and at the same time, the rotation guide plate 19 integrally attached to the mounting shaft 18 is also rotated. The feed pawl 25 is engaged with the locking portion 20 from
The circular saw 21 is rotated clockwise by the same angle for the feeding operation, and the circular saw 21 is eccentrically rotated about the attachment @18 by one piece so that the next cutting edge 22 is in the position of the grinder 4.

Therefore, as described above, when the next cutting edge 22 is rotated to the grinder 4 position by one back-and-forth rotation operation of the operating knob 17, the slide table 8 is moved back and forth by the previously adjusted sliding movement. By moving back and forth by the length, the next cutting edge 22 is also reground by the grinder 4 in the same manner as described above.

Therefore, when the number of blades of the circular #I 21 is 8, by repeating the above-mentioned operation 8 times, it is possible to efficiently regrind the blade edge of the 8-blade circular saw 21.

In addition, if the blade edge re-polishing operation as described above is repeated several times, the outer periphery of the circular saw 21 will become deformed and become unbalanced during use, making it impossible to perform accurate cutting. Of course, it will disappear, but it will generate noise.In such a case, turn the operating handle to position A, move the slide table 8 all the way back to the front, and then turn the slide adjustment device 35. As a result, the sliding table 8 is moved forward to a position where the grinder 4 and the outer circumferential end 22a of the cutting edge of the hemp 21 coincide with each other, and the operating handle 1T is rotated clockwise from the A position to the B position. Then, the rotating plate 11 is rotated by the peripheral wall 10 of the rotating reference disk 9, and at the same time, the rotating guide plate 19 directly connected to the mounting shaft 18 is also engaged with the locking portion 20 from the beginning. The feeding claw 25 is rotated clockwise by the opening angle for the feeding rotation operation, and the circular saw 21 is eccentrically rotated by one frame with respect to the rotating plate 11 so that the next cutting edge 22 is at the position of the grinder 4. Ru.

Therefore, by rotating the operating handle 1701 times, the outer periphery of the circular saw 21 is rotated while being in sliding contact with the grinder 4. Accurately polished to a circular arc surface with a specified radius. When the polishing work on the outer periphery is completed by the above operation, operate the operating handle 1.
If you turn 7 counterclockwise from position B to position A,
The rotation guide plate 19 is eccentrically rotated in the same counterclockwise direction as the rotation direction of the rotation plate 11 until the range of the play distance 1 is reached, and then, when the play distance 1 is exceeded, the locking portion 20 is moved to the stopper. 2
8, the rotation guide plate 19 is forcibly prevented from rotating counterclockwise, and the rotation guide plate 19 and the circular saw 2
1 are both eccentrically rotated with respect to the rotating plate 11 in a direction opposite to the rotating direction of the operating handle 17, and automatically so that the supinated end 22a of the circular saw 21 matches the set position of the grinder 4. The blade edge 22 is moved eccentrically, and the blade edge 22 is returned to a state where it can move to the next outer circumference # farm work without grinding against the grinder 4.

Therefore, if you repeat the operation of rotating the operating handle 17 toward you 8 times as described above, you will get a round i# with 8 blades! The outer periphery of the saw 21 is polished to a precise shape, and a remanufactured circular saw that does not rotate incorrectly or generate abnormal noise during use can be obtained.

Also, 4-blade, 3-blade and 2-blade circular saws 21', 21"
, 21, when performing the blade edge polishing work of the respective circular saws 21.
21. Since the cutting edges 22', 22", and 22# of 21 are formed in a tapered shape that is MM with respect to the center line, the mounting position of the grinder 4 must be shifted to the right from the state shown in the first figure. After mounting the sliding table 8 to the Y position, move the slide table 8 back as far as it will go, and at the same time return the operating handle 17 to the B position.
Single-blade or two-blade circular saw 21.21. ．． 21 to the locking part 20
and the blade edges 22', 22'', 22', respectively.Next, the sliding adjustment device 35 adjusts the base end of the blade edge of each circular saw 21'', 21', 21' to the outer edge of the grinder 4. After adjusting the longitudinal sliding length so that the sliding table 8 can move forward to the position where it contacts, the sliding table 8 is moved back to the front position again, and then the grinder 4 is rotated at high speed, and the sliding table 8 is moved forward. By reciprocating the surface pressure back and forth by the sliding length, the cutting edges 22', 22.22, whose outer peripheral ends 22a', 22a'', and 22a' are rounded, are reground by the grinder 4 so that they become acute-angled. .

After the circular saws 21', 21", and 21' have been resharpened by the above operation, except for the three-blade circular saw 21", move the sliding table 8 all the way to the front. Move the operating handle 11 from position B twice in case of 4 blades,
In the case of a two-blade, when it reciprocates four times, the rotation guide plate 19 rotates 2 frames (90 degrees) or 4 frames (180 degrees) by the feed operation of the feed pawl 25.
degree) is rotated clockwise, rotates the circular saws 21', 21' respectively, or rotates them multiple times, and then the next cutting edge 22', 22' is rotated clockwise.
is rotated to the grinder 4 position, so slide table 8
When the blades are moved back and forth to the grinder 4 by the sliding adjustment length, the next cutting edges 22 and 22' are also reground by the grinder 4.

In addition, in the case of a 3-blade circular saw 21", the rotation guide plate 19
Since the number of locking portions 20 provided on the periphery of the rotary guide plate 19 is even, the rotation angle for one frame feed of the rotary guide plate 19 is not compatible with the three-blade circular saw 21'. , without rotating the rotating plate 11, set the cutting edge 22' of the three blades on the mounting shaft 18 so as to contact the outer periphery of the grinder 4 each time, and then set the cutting edge 22' while reciprocating the sliding table 8 back and forth. 22' is re-polished.

Also, four-blade, three-blade, and two-blade circular saws 21'.

When it is desired to regrind the outer periphery of 21, 21' into an accurate circular shape, return the setting position of the grinder 4 to the X position shown in the first figure, and with the operation handle 17 in the B position, the 4 is attached to the mounting shaft 18. Single-blade, three-blade and two-blade circular saw 21'
, 21', 21' respectively, and use one hand to cut each circular saw 21.
', 21', 21' are rotated manually in one direction while applying them to the grinder 4.
, 211 are regrinded into an accurate circular shape, and will not cause unbalanced rotation or noise when the remanufactured circular saw is used.

Note that the 3-blade circular saw 21# and the 4-blade circular saw 21' have cutting edges 22' and 22' on both the front and back sides, so when polishing the cutting edges 22" and 22", turn them over and do the above-mentioned operation. You can perform the same operation.

Embodiment The present invention will be described with reference to a preferred embodiment shown in the accompanying drawings.

Reference numeral 1 denotes a mounting base with legs that can be installed at any location, and a long mounting hole 3 is provided on the front side of the mounting base 1. Installed mounting device 5
A polishing device 2 is installed so as to be movable along an elongated attachment hole 3 through the attachment hole 3. The grinder 4 directly connected to the tip side of the polishing device 2 is arranged on a horizontal surface and is rotated at high speed with a mounting angle of 45 degrees.The mounting device 5 is moved to the X position of the mounting slot 3 by the tension tool 6. When installed through the 4-blade, 3-blade, and 2-blade circular saws 21', 2, as well as the cutting edge and outer periphery grinding work of the 8-blade circular saw 21,
1' and 21', and the attachment device 5 is changed from the X position of the long mounting hole 3 to the X position. circular saw 21',
The cutting edge polishing work of 21' and 21' can be easily performed.

On the opposite side of the mounting base 1, two inclined guide rails 1, 1 on the left and right sides are installed parallel to each other at an interval so as to extend in the front and back direction with respect to the polishing device 2 installed at the X position. In addition, between the two left and right tilting guide rails 7.7, there is a flat plate-shaped sliding table 80 on both sides of the lower part, in order to be able to slide in the front and back direction along the two tilting guide rails 7.7. The sliding plate 8a is bent outward and downward by 5M to form a somewhat more acute angle than the inclination angle of the inclined guide rail 7.7.

8a is fitted. A cylindrical rotation reference disk 9 with a peripheral wall 10 erected thereon is mounted at a substantially central position on the sliding table 8 via a tensioning device. A rotating plate 11 is fitted over the entire circumference with a flange 12 bent downward so that the plate 11 can be fitted to the peripheral wall 10 from above. Arc-shaped elongated holes 13 and 13 each having a length of 45 degrees to 50 degrees are concentrically drilled at symmetrical positions on the upper surface of the rotation reference disk 9, and the upper surface of the rotation plate 11 to be fitted is symmetrical. The position is the arcuate long hole 1
A connecting hole 14.14 corresponding to 3.13 is drilled, and a connecting tool 15.15 is passed through the arcuate long hole 13.13 and the connecting hole 14.14. The two are connected so that they can freely rotate left and right within a range of motion.

A bearing cylinder 16 is installed upright at the eccentric position of the rotating plate 11, and an operating handle 17 is attached to one side of the rotating plate 11, and the operating handle 17 is moved from the A position to the B position.
By rotating the rotating device 11 toward the front so as to reach the position □, the entire rotating device 11 is rotated within a rotation range of 45 degrees to 50 degrees along the peripheral wall 10 of the rotating reference disk 9. The mounting @ 18 is freely mounted on the bearing sleeve 16 in a rotatable state, and the mounting @ 18 button has a circumference kf: IC even number, for example, 8 locks, and the part 20 is equally divided. A dish-shaped disc-shaped rotary guide disk 19 provided on the rotary guide disk 19 is directly connected to the rotary guide disk 19, and eight cutting edges 22 and four cutting edges 22 are provided on the upper surface of the rotating guide disk 19.
', a circular saw 21 consisting of three cutting edges 22 and two cutting edges 22.21', 21", 21' can be exchangeably attached to the mounting shaft 18.
This is firmly attached using the clamping plate 23 fitted into the mounting shaft 18 and the fastening fitting 24 screwed into the distal end side of the mounting shaft 18.

In addition, when attaching the 8-blade circular saw 21 and the 4-blade circular saw 21' to the mounting ￥@18, the locking part 20 and the cutting edge 2
2 and 22' are regulated so that they match, respectively. Therefore, according to the above setting conditions, the grinder 4 is positioned at the outer peripheral ends 22a, 22a' of the cutting edges 22, 22' of the circular saws 21, 21'.

The above-mentioned operation handle 17 is integrally provided with a mouth-shaped bending rod 17a whose one end is not fixed to the rotary plate 11 on the distal end side, and a feed pawl 25 is mounted on the bending rod 17a.
At the same time, the towed projectile 26 is stretched across the base end of the feed pawl 250 and the operating knob 17,
The biasing elasticity of the towing projectile 26 causes the tip side of the feed pawl 25 to be locked to one of the locking portions 20 provided on the periphery of the rotation guide disk 19.

Once, by rotating the operating handle 11 from the A position to the B position, the rotation guide plate 19 directly connected to the mounting shaft 18 was rotated by 45 degrees to The mounting shaft 18, which can be rotated clockwise over a range of 50 degrees and is equipped with a rotation guide plate 19, is attached to the rotation plate 1.
K is eccentrically rotated with respect to 1.

A bending support member 27 is erected at the rear position of the slide table 8, and a substantially central portion of a stopper 28 is pivotally attached to the upper surface of the bending support member 27, and one end of the stopper 28 and the bending support The towed projectile 30 is stretched over a supporting member 29 which is set upright on the slide table 8 in the vicinity of the material 27, and the leading end side of the striker 28 is pressed against the periphery of the rotation guide plate 190 by the traction elasticity. urge

The relative positional relationship between the locking portion 20 of the rotary guide plate 19, the feed pawl 25, and the stopper 28 is as shown in the fourth figure. In the forcibly engaged state, the stopper 28 is not engaged with the other locking parts 20, so that a play distance l of the length between the stopper 28 and the other locking parts 20 is provided. It is set. Therefore, by setting the play interval l as described above, when the operating handle 11 is rotated from the B position to the A position, the rotating plate 11 will be recoiled along the circumferential wall 10 of the rotating reference disk 9. As the rotation guide plate 19 is rotated clockwise, the rotation guide plate 19 is rotated until the play distance l range of the length becomes the rotation guide plate 19.
1 and eccentrically rotated in the counterclockwise direction, which is the same direction as the rotation direction of the operating knob 17, but with a -tan play interval! When the range is exceeded, the stopper 28 is locked to the locking part 20 by the biasing elasticity of the towing projectile 30, and the rotation guide plate 19 is forcibly prevented from rotating counterclockwise. Not only the moving guide plate 19 but also the eight-blade circular saw 21.4 mounted on the mounting shaft 18.
Both the single-blade circular saw 21' and the two-blade circular saw 21' are installed in the opposite direction to the direction of the force until the operating handle 170 is rotated until the restoration rotation by the operating knob 17 is completed (position B). The cutting edges 22 of the circular saws 21, 21', 21' are slightly rotated around the rotating disc 11 while being slightly rotated about the axis 18.
, 22a' are automatically eccentrically moved to match the outer circumferential line of the grinder 4.

For the four-blade circular saw 21', press the operating handle 11 twice, and for the two-blade circular saw 21'', press the operating handle 1 twice.
The above effect can be achieved by reciprocating 7 four times.

In order to accurately stop the rotation range of the operating handle 17 at position B, which is 45 degrees from position A, a stop device 31 is provided at position B. This stopping device has a compression bullet 3 attached to the tip side of a projecting plate 32 whose base end is attached to a sliding table 8.
The operation is performed by advancing and retracting the screw rod 33 with a handle wrapped with 4.
The rotation range of the handle 11 can be finely adjusted.

At position A, the operating handle 17 is secured by the stopper 28 being held in the locking portion 20 and by the engagement with the connecting tool 15.
A stop device is not required at the person position since the is prevented from being rotated further counterclockwise.

Therefore, by retracting the handle-attached screw rod 33, the rotation range of the operating handle 170 can be adjusted to a maximum of 50 degrees f, thereby making it possible to increase the cutting margin of the blade edge during the blade edge polishing operation. 35 is the X position or Y of the mounting base 1
A sliding adjustment device 35 is shown in FIG. Like,
A rotary wire rod 37 with a handle mounted on a pair of front and rear bearing fittings 36 and 36 installed at the front and rear positions on the mounting base 1 is positioned between the sliding base 8 and the mounting base 1. and a movable piece 38 screwed to the rotary wire rod 37, and a stop fitting 39 that collides with the movable piece 38 is provided on the front side of the sliding base 8, so that the rotary wire rod 37 By moving the movable piece 38 back and forth along the rotary line rod 37 by the left and right rotation operation, the sliding length of the slide table 8 can be finely adjusted.

After the sliding adjustment dimension of the desired length is obtained by the sliding adjustment device 35 described above, the sliding table 8 is moved to the nozzle 40 mounted on the front side of the sliding table 8. By pushing and pulling, the moving piece 38 can be slid back and forth along the inclined guide rail 7.7 until it collides with the stop fitting 39 and stops.

Further, a gate-shaped support fitting 41 is placed on the mounting base 1 near the contact area between the grinder 4 and the circular saws 21, 21, 21.21, and a transparent safety plate is placed on the upper horizontal part of the support fitting 41. One end of the cover 42 is hinged with a hinge 43 so as to be able to move back and forth to cover the upper part of the contact part, thereby preventing the cutting powder from flying into the operator during the polishing work, thereby allowing the circular saw correction polishing work. Make sure it can be done safely.

In addition, the installation location of the polishing device 2 should be set to the X position when using 8 blades.
In addition, the reason why the 4-blade, 3-blade, and 2-blade models are changed to the Y position is that the 8 blade edges 22 are the same as the circular saw 2.
1.In contrast, 4-blade, 3-blade, and 2-blade round AI21.21.21
The cutting edges 22, 22, and 22 are all formed in a tapered shape with respect to the center line, so when the polishing device has 4 blades, 3 blades, or 2 blades, compared to when it has 8 blades. This is because unless the installation position of No. 2 is installed at the Y position rather than the X position, the cutting edge cannot be accurately polished by the back and forth movement of the sliding table 80.

The mounting position 5 for installing the ωF calendar device 2 at a predetermined location at the X position or Y position on the mounting base 1 is as shown in No. 15 (1).
A base end piece of a substantially elliptical mounting frame 45 is connected by a rotating shaft 45 to an inverted T-shaped mounting base 44 mounted on the mounting base 1 via a tension member 6, and the mounting frame 45 A screw shaft protruding from the mounting base 44 is inserted into an arcuate elongated hole 47 drilled in the base end piece of the frame 45, and a nut 48 is screwed onto the end of the screw shaft. The polishing device 20 can be rotated in the front-rear direction about the rotation shaft 46, so that the front-rear tilt angle of the polishing device 20 can be adjusted to a position where it is easy to work.

In addition, as shown in Figure 16 (on the front side of the mounting base 1, one or several 4i metal fittings 49 shorter than the height of the sliding table 8 are installed, and the metal fittings 49 have locking pins. Even if the sliding table 8 is moved forward 1i111 by inserting and removing the locking pin 50, the locking operation of the locking pin 50 locks the locking pin 50 so that it cannot be removed from the mounting base 1, and the locking pin 50
When the sliding table 8 is pulled out from the metal fitting 49, the sliding table 8 can be removed from the mounting table 1 with a single touch operation and cleaned.

The rotation reference disk 9 described above does not have to be separate from the slide table 8, but a part of the wall plate of the slide table 8 may be bulged and formed into an integral shape by press working.

Effects of the Invention In short, since the present invention has the above configuration, the sliding table 8 can be moved back and forth with respect to the grinder 3, and the rotating reference disk 9 can be rotated by a predetermined angle along the peripheral wall 10. Due to the intermittent rotational sweeping of the plate 11, the cutting edges of the 8-blade and 4-blade circular saws 21 and 21' mounted on the mounting shaft 18 rotatably mounted on the rotary plate 11 are removed. 22.22
The outer periphery of the circular saw 21.21' is also polished to an accurate shape, and the outer periphery of the circular saw 21.21' can be continuously polished to regenerate it as a sharp cutting edge.
It is possible to allow the saw to rotate under normal conditions without rotating incorrectly or emitting abnormal noise, and even if it is a three-blade or two-blade circular saw 21", 21', By moving the slide table 8 back and forth and manually rotating the circular saws 21'' and 21' intermittently about the mounting shaft 18, polishing of the cutting edge 22 and 22 and polishing the outer periphery can be easily accomplished. Of course, since the rotating plate 11 is rotated along the circumferential wall 10 of the rotation reference disk 9, wear due to rotation is minimized and the rotating plate 11 can be rotated accurately at all times. However, since the rotary plate 11 is fitted and connected to the rotary reference disk 9, problems may occur during the operation. This has the effect of preventing the cutting powder layer from entering between the rotating plate 11 and the rotating reference disk 9, smoothing the rotation of the rotating plate 110, and promoting the improvement of work efficiency. play.
