[0036] Working principle of the present invention:

[0037] First, the rotating disk 510 is controlled to rotate, so that the rotating disk 510 drives the connecting shaft 59 fixedly connected thereto to rotate, thereby causing the connecting shaft 59 to drive the rotating rod 53 fixedly connected thereto to rotate. When the rotating rod 53 rotates, it drives the thread line 1 54 and the thread line 2 55 provided on the outer side thereof to rotate synchronously, thereby controlling the two thread blocks 56 to move toward each other. When the thread block 56 moves, it drives the clamping block 57 fixedly connected thereto to move synchronously, thereby clamping the gear to be processed;

[0038] Then, the motor 310 is controlled to work, so that the motor 310 drives the driving shaft 311 fixedly connected to its output shaft to rotate, and the driving shaft 311 will drive the residual gear 312 fixedly connected to it to rotate when it rotates.

[0039] After the first tooth surface of the gear is polished, the residual gear 312 will mesh with the full gear 1 313, so that the full gear 1 313 drives the rotating shaft 38 fixedly connected thereto to rotate, and the rotating shaft 38 will drive the driving wheel 1 37 fixedly connected thereto to rotate when rotating, so that the driving wheel 1 37 drives the driven wheel 1 35 to rotate through the belt 1 36, and the driven wheel 1 35 will drive the connecting rod 34 fixedly connected thereto to rotate when rotating, so that the connecting rod 34 drives the driving gear 33 fixedly connected thereto to rotate, and the driving gear 33 will drive the driven gear 31 meshed therewith to rotate when rotating, so that the driven gear 31 drives the movable plate 4 fixedly connected thereto to rotate, so that the next tooth surface can be rotated to the polishing device for polishing;

[0040] When the motor 310 is working, it will drive the driving wheel three 713 fixedly connected to its output shaft to rotate, so that the driving wheel three 713 drives the driven wheel three 711 to rotate through the belt three 712. When the driven wheel three 711 rotates, it will drive the linkage shaft 710 fixedly connected to it to rotate, so that the linkage shaft 710 drives the threaded rod two 77 fixedly connected to it to rotate. When the threaded rod two 77 rotates, it will drive the threaded seat 76 threadedly connected to it to move, so that the threaded seat 76 drives the mounting plate 74 fixedly connected to it to move. When the mounting plate 74 moves, it will drive the brush 75 fixedly connected to it to move, so that the brush 75 sweeps the waste generated by grinding into the collection box 9 for collection and treatment of the waste.
