[0034] Working principle: First, the angle of the grinding assembly 11 is adjusted according to the degree of chamfering of the brake pad, that is, the turntable 44 is rotated, the rotation of the turntable 44 drives the worm 43 to rotate, the rotation of the worm 43 drives the mutually meshing worm gears 42 to rotate, the rotation of the worm gear 42 drives the rotating shaft 41 to rotate, and the rotation of the rotating shaft 41 drives the grinding assembly 11 to rotate, so that the angle of the grinding assembly 11 is adjusted, so that it can be adjusted according to the degree of chamfering of the brake pad, and then the brake pad that needs to be chamfered is placed in the placement box 22, and then the motor 29 is started, so that the motor 29 starts to work, the output shaft end of the motor 29 rotates to drive the threaded rod 2 to rotate, and the rotation of the threaded rod 2 drives the threaded slider 21 to slide The guide rod 24 slides in the movable groove 12, and the threaded slider 21 moves to drive the placement box 22 and the brake pad to move, so that the guide rod 24 slides in the guide groove 31. During the moving process, the guide rod 24 moves in the direction of the brake pad, and the movement of the guide rod 24 drives the fixed plate 26 to move. The movement of the fixed plate 26 compresses the compression spring 27, so that the guide rod 24 drives the clamping plate 25 to move, and the brake pad is clamped by the two clamping plates 25, and then automatically moves to the grinding assembly 11 for grinding. When the placement box 22 is reset, the rebound of the compression spring 27 drives the guide rod 24 to move outward, thereby losing the clamping of the brake pad, which is convenient for material removal and loading, thereby achieving the purpose of automatic grinding and chamfering.
