When the slider moves, the position of the positioning shaft will be adjusted. After the positioning shaft moves out of the positioning hole, the position of the rotating disk is no longer positioned. The forward and reverse rotation of the output end of the driving motor will control the positioning shaft to move forward or backward. When the positioning shaft is inserted into the positioning hole, the position of the rotating disk will be positioned, thereby preventing the rotating disk from sliding, thereby improving the working stability of the high-precision automatic indexing tooling. When the external processing component processes the workpiece transmitted by the high-precision automatic indexing tooling, the position of the rotating disk is prevented from shaking, which affects the processing effect.

When the long rod 22 moves, the support plate 23 will move smoothly. When the support plate 23 drives the sponge plate 24 to move to the same horizontal plane as the rotating disk 3, the support plate 23 is rotated. After the sponge plate 24 contacts the top of the rotating disk 3, the rotating disk 3 is rotated, and the sponge plate 24 scrapes off the adsorbent on the surface of the rotating disk 3, so as to achieve the purpose of quickly scraping and cleaning the adsorbent on the surface of the rotating disk 3.

[0029] Embodiment 2:

[0030] refer to Figure 1 , Figure 2 and Figure 4As shown, an annular groove 10 is provided on the rotating disk 3, and a clamping block 11 is fixedly installed inside the workbench 1, and the clamping block 11 is clamped inside the annular groove 10.

[0031] Specifically, the rotating disk 3 is provided with positioning holes 12 in an array, and a square groove 13 is fixedly installed inside the workbench 1 , and the workbench 1 provides an installation space for the square groove 13 .

[0032] Specifically, a slider 14 is fixedly installed inside the square groove 13, and a positioning shaft 19 is fixedly connected to the slider 14, and one end of the positioning shaft 19 extends to the inside of one group of positioning holes 12. The slider 14 provides an installation space for the positioning shaft 19. When the positioning shaft 19 is inserted into the inside of the positioning hole 12, the position of the rotating disk 3 is positioned, thereby preventing the position of the rotating disk 3 from sliding, thereby improving the working stability of the high-precision automatic indexing tooling, and when an external processing component processes the workpiece transmitted by the high-precision automatic indexing tooling, the position of the rotating disk 3 is prevented from shaking, which affects the processing effect.

[0033] Specifically, a driving motor 18 is provided inside the square groove 13, and the driving motor 18 is electrically connected to the distribution box 2, and a threaded screw 17 is fixedly connected to the output end of the driving motor 18, and a threaded sleeve 16 is fixedly installed on the slider 14, and the threaded screw 17 is threadedly connected to the threaded sleeve 16. When the driving motor 18 is working, the threaded screw 17 will be driven to rotate, and when the threaded screw 17 rotates, the position of the threaded sleeve 16 will be moved, and then when the position of the threaded sleeve 16 moves, the position of the slider 14 will be driven to move, and when the slider 14 moves, the position of the positioning shaft 19 will be adjusted. After the positioning shaft 19 moves out of the positioning hole 12, the position of the rotating disk 3 will no longer be positioned, and the forward and reverse rotation of the output end of the driving motor 18 will control the positioning shaft 19 to move forward or backward.

[0034] Specifically, a guide rod 15 is fixedly installed inside the square groove 13 , and the guide rod 15 passes through the inside of the slider 14 . When the slider 14 moves, the guide rod 15 guides the slider 14 to enable the slider 14 to slide smoothly.

[0035] Working principle: First, when using the high-precision automatic indexing tooling, the threaded ring 4 is used to fix the connection with the fixture. After the fixture clamps the workpiece, the driving motor 5 drives the worm 7 to rotate. When the worm 7 rotates, the worm wheel 9 rotates. When the worm wheel 9 rotates, the support rod 8 rotates, and then the rotating disk 3 rotates. When the rotating disk 3 rotates, the workpiece is driven by the fixture to move to the next station for processing. The contact between the magnet 25 and the iron block 26 will limit the position of the support plate 23. When the adsorbent on the surface of the high-precision automatic indexing tooling needs to be adjusted, the workpiece 25 is moved to the next station for processing. When cleaning, pulling the support plate 23 will drive the long rod 22 to move smoothly inside the limit ring 21. When the long rod 22 moves, the support plate 23 will move smoothly. When the support plate 23 drives the sponge plate 24 to move to the same horizontal plane as the rotating disk 3, the support plate 23 is rotated to make the sponge plate 24 contact with the top of the rotating disk 3, and then the rotating disk 3 is rotated. The sponge plate 24 will scrape off the adsorbed matter on the surface of the rotating disk 3, so as to achieve the purpose of quickly scraping and cleaning the adsorbed matter on the surface of the rotating disk 3. There is no need to use external tools for cleaning, which improves the practicability of high-precision automatic indexing tooling.

[0036] Secondly, the driving motor 18 will drive the threaded screw 17 to rotate. When the threaded screw 17 rotates, the position of the threaded sleeve 16 will move, and then when the position of the threaded sleeve 16 moves, the position of the slider 14 will be driven to move. When the slider 14 moves, the position of the positioning shaft 19 will be adjusted. After the positioning shaft 19 moves out of the positioning hole 12, the position of the rotating disk 3 is no longer positioned. The forward and reverse rotation of the output end of the driving motor 18 will control the positioning shaft 19 to move forward or backward. When the positioning shaft 19 is inserted into the positioning hole 12, the position of the rotating disk 3 will be positioned, thereby preventing the position of the rotating disk 3 from sliding, thereby improving the working stability of the high-precision automatic indexing tooling. When the external processing component processes the workpiece transmitted by the high-precision automatic indexing tooling, the position of the rotating disk 3 is prevented from shaking, which affects the processing effect.
