[0022] like Figure 2As shown, a clamping table 4 is provided on the top of the processing table 1, and a clamping mechanism is provided inside the clamping table 4. The clamping mechanism includes a round rod 401, a moving block 402, a connecting column 403, a chuck 404, a sliding column 405, a cross plate 406, an inclined groove 407 and an electric telescopic rod 408.

The other end of 03 passes through the top of the processing table 1, the chuck 404 is fixedly connected to the top of the connecting column 403, the sliding column 405 is fixedly connected to the bottom of the moving block 402, the horizontal plate 406 is movably arranged inside the clamping table 4 and is located at the bottom of the moving block 402, the inclined groove 407 is opened at the top of the horizontal plate 406 and passes through the top plate 3, the sliding column 405 is slidably connected to the inside of the inclined groove 407, the electric telescopic rod 408 is fixedly connected to the inside of the clamping table 4, and the electric telescopic rod The output end of the retractable rod 408 is fixedly connected to the cross plate 406. Through the mutual cooperation of the clamping mechanism, when processing the gear, the gear can be placed on the inner side of the chuck 404 on the top of the processing table 1, and then the electric telescopic rod 408 is operated to push the cross plate 406 backward. After the cross plate 406 moves backward, it squeezes the sliding column 405, causing the sliding column 405 to move inward at the same time along the direction of the inclined groove 407. The inward movement of the sliding column 405 can drive the moving block 402 to move smoothly inward on the surface of the round rod 401 at the same time. When the moving block 402 moves inward at the same time, the chuck 404 can be driven to move inward at the same time through the connecting column 403.

[0027] The working principle of the present invention is as follows: when grinding the gear, the gear can be placed inside the chuck 404 on the top of the processing table 1, and then the electric telescopic rod 408 is operated to push the horizontal plate 406 backward. After the horizontal plate 406 moves backward, it squeezes the sliding column 405, so that the sliding column 405 moves inward at the same time along the direction of the inclined groove 407. The inward movement of the sliding column 405 can drive the moving block 402 to move inward smoothly on the surface of the round rod 401 at the same time. When the moving block 402 moves inward at the same time, the chuck 404 can be driven to move inward at the same time through the connecting column 403. The gear can be fixedly clamped by the chuck 404 when it moves inward at the same time, and the operator can rotate the wire in the opposite direction. Rod 202, the rotation of the screw rod 202 can drive the threaded sliding block 203 to move downward smoothly and slowly inside the vertical groove 201. The downward movement of the sliding block 203 can drive the grinding motor 304 and the grinding shaft 305 to move downward through the top plate 3, thereby adjusting the output height of the grinding shaft 305. At the same time, when the gear diameters are not uniform, the staff can also rotate the screw 303. The rotation of the screw 303 can squeeze the connecting block 302 to slide inside the horizontal groove 301. The sliding of the connecting block 302 can drive the grinding motor 304 and the grinding shaft 305 to move, and the grinding position of the grinding shaft 305 can be flexibly adjusted, which is suitable for grinding gears of different types and improving the versatility of the equipment.
