[0025] Please refer to Figure 1 and Figure 2 .

[0026] The grinding mechanism 2 includes a motor 21, a rotating disk 22 and a limiting cover 23;

[0027] Furthermore, the outer side of the motor 21 is fixedly connected to the base 1, and the output shaft of the motor 21 is fixedly connected to the center of one end of the turntable 22 at one end of the motor 21 close to the base 1;

[0028] Furthermore, the outer side of the turntable 22 is detachably connected with a plurality of grinding blocks 221, and the plurality of grinding blocks 221 are arranged around the outer side of the turntable 22. The design that the grinding blocks 221 are detachably connected and installed on the outer side of the turntable 22 can remove the worn grinding block 221 and replace it with a new grinding block 221 when a single grinding block 221 is greatly worn, so as to avoid the worn grinding block 221 affecting the quality of the grinding of the metal parts 8 of the present device; arc-shaped grinding grooves are provided on both sides of the grinding blocks 221, and the grinding grooves are away from the turntable 22.

There is a certain distance between the limiting cover 23 and the grinding block 221, and the contact piece is close to the grinding area; a feeding track 24 is fixedly connected to one side of the limiting cover 23, and a plurality of ungrinded metal parts 8 are placed in the feeding track 24; when the turntable 22 rotates, each grinding area moves closer to the feeding track 24 in turn, and the feeding track 2 The unpolished metal parts 8 on the 4 are dropped into each polishing area one by one in turn. When the rotation of the turntable 22 pushes the unpolished metal parts 8 into the limiting cover 23, the contact piece touches the outer side of the unpolished metal parts 8. The contact piece uses its own friction force to push the unpolished metal parts 8 to rotate in the polishing area.
