Detailed implementation mode
[0021] As Figures 1-6 shown, the present utility model provides a technical solution: a clamping tool for gear grinding and machining, including a support leg 1, a workbench 2 is fixedly installed on the upper surface of the support leg 1, a grinding device 3 is fixedly installed on the top of the workbench 2, a positioning mechanism 4 is arranged on the upper surface of the workbench 2, and an ejecting mechanism 5 is arranged on the upper surface of the workbench 2.
[0022] The above positioning mechanism 4 includes: a fixed block 401, a round rod 402, a large tooth 403, a small tooth 404, a bidirectional threaded rod 405, a spring 406, an arc-shaped block 407, a short rod 408, a clamping rod 409, a torsion spring 410, a rectangular block 411 and a positioning plate 412. The rectangular block 411 is fixedly installed on the upper surface of the workbench 2. The positioning plate 412 slides inside the rectangular block 411. The inner wall of the positioning plate 412 meshes with the outer wall of the bidirectional threaded rod 405. A fixed block 401 is fixedly installed on the outer wall of the rectangular block 411. A round rod 402 is rotatably connected to the inner wall of the fixed block 401. A large tooth 403 is fixedly installed on the outer wall of the round rod 402. A small tooth 404 is slidably installed on the outer wall of the round rod 402. The large tooth 403 and the small tooth 404 are in a meshed state. A bidirectional threaded rod 405 is sleeved on the outer wall of the round rod 402. The bidirectional threaded rod 405 rotates inside the fixed block 401. A spring 406 is fixedly installed on the outer wall of the small tooth 404. One end of the spring 406 is fixedly installed on the outer wall of the small tooth 404, and the other end of the spring 406 is fixedly installed at the end of the bidirectional threaded rod 405. An arc-shaped block 407 is fixedly installed at the end of the round rod 402. A short rod 408 is fixedly installed at the end of the bidirectional threaded rod 405. A clamping rod 409 is rotatably installed on the outer wall of the short rod 408. A torsion spring 410 is sleeved on the outer wall of the short rod 408. One end of the torsion spring 410 is fixedly installed on the outer wall of the clamping rod 409, and the other end of the torsion spring 410 is fixedly installed on the outer wall of the short rod 408. Place an item on the rectangular block 411. By rotating the round rod 402, the large tooth 403 drives the small tooth 404, and then drives the bidirectional threaded rod 405 to rotate through the spring 406. At this time, the positioning plates 412 will approach each other as the bidirectional threaded rod 405 rotates and fix the item. When the item is fixed, the bidirectional threaded rod 405 will be subject to resistance. At this time, the rotation of the large tooth 403 will cause the small tooth 404 to bounce off instantaneously so that the small tooth 404 no longer meshes with the large tooth 403. By then, the round rod 402 will rotate idly and will no longer drive the bidirectional threaded rod 405 to continue rotating. After the grinding work is completed, by rotating the round rod 402 in the reverse direction, the arc-shaped block 407 at the end of the round rod 402 squeezes the clamping rod 409 and drives the bidirectional threaded rod 405 to rotate in the reverse direction and makes the positioning plates 412 move away from each other to release the fixation of the item. While the positioning plates 412 move away from each other, the hinge rod 503 will push the top plate 502 to slide upward inside the hollow block 501 and eject the item to facilitate the staff to take the item.
[0023] The above-mentioned ejection mechanism 5 includes: a hollow block 501, a top plate 502, and a hinge rod 503. The hollow block 501 is fixedly installed on the inner wall of the rectangular block 411. The top plate 502 is slidably installed on the inner wall of the hollow block 501. The outer wall of the top plate 502 is hinged with the hinge rod 503. One end of the hinge rod 503 is fixedly installed on the outer wall of the top plate 502, and the other end of the hinge rod 503 is hinged on the outer wall of the positioning plate 412. While the positioning plates 412 approach each other, the hinge rod 503 will pull the top plate 502 to slide downward on the inner wall of the hollow block 501 to level the article.
[0024] Working principle: Place the article on the rectangular block 411. By rotating the round rod 402, the large gear teeth 403 drive the small gear teeth 404, and then drive the bidirectional threaded rod 405 through the spring 406. At this time, the positioning plates 412 will approach each other as the bidirectional threaded rod 405 rotates and fix the article. When the article is fixed, the bidirectional threaded rod 405 will be subject to resistance. At this time, the rotation of the large gear teeth 403 will cause the small gear teeth 404 to bounce off instantaneously so that the small gear teeth 404 no longer mesh with the large gear teeth 403. By then, the round rod 402 will rotate idly and will no longer drive the bidirectional threaded rod 405 to continue rotating. While the positioning plates 412 approach each other, the hinge rod 503 will pull the top plate 502 to slide downward on the inner wall of the hollow block 501 to level the article. At this time, start the grinding device 3 to grind the article. After the grinding work is completed, reverse-rotate the round rod 402 so that the arc-shaped block 407 at the end of the round rod 402 presses the latch rod 409 and drives the bidirectional threaded rod 405 to rotate in the reverse direction and make the positioning plates 412 move away from each other to release the fixation of the article. While the positioning plates 412 move away from each other, the hinge rod 503 will push the top plate 502 to slide upward on the inner wall of the hollow block 501 and eject the article to facilitate the staff to take the article. It should be noted that when the round rod 402 rotates forward, the latch rod 409 will not limit the arc-shaped block 407. The latch rod 409 will be pressed by the arc-shaped block 407 and rotate upward. When the pressing ends, the torsion spring 410 will make the latch rod 409 rotate downward to complete the reset. Only when the round rod 402 rotates in the reverse direction will the latch rod 409 be stuck into the arc-shaped block 407 and drive the bidirectional threaded rod 405 to rotate in the reverse direction.
[0025] Generally speaking, the above has described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
