[0002] Fasteners are also called standard parts in the market. They are a general term for a type of mechanical parts used to fasten two or more parts (or components) into a whole. They are characterized by a wide variety of specifications, different performances and uses, and a high degree of standardization, serialization, and generalization. Fasteners are the most widely used basic mechanical parts and are in great demand. Polishing equipment is required for the processing of fasteners.

The fastener processing and polishing device includes a placement plate, and two placement plates are arranged on one side of the placement plate. The close ends of the two placement plates are rotatably connected with a screw and a screw nut. The screw nut is threadedly connected to the circumferential surface of the screw. When the workpiece needs to be polished, it can be placed in the placement groove, and then the positioning mechanism fixes it, and then the screw is rotated to drive the screw nut to descend, and the polishing machine body is aligned with the workpiece surface arranged in the placement groove for polishing. Through the above design, manual polishing can be replaced, and the device has a simple structure and is easy to use, with low cost and cost, and is easy to promote.

[0004] The above-mentioned fastener processing and polishing device still has certain shortcomings. When the workpiece needs to be polished, it can be placed in the placement groove, and then the positioning mechanism can fix it, and then the screw rod is rotated to drive the screw nut to descend, and the polishing machine body is aligned with the workpiece surface set in the placement groove for polishing. However, when the polishing machine is in use, it is difficult to adjust the angle, which makes it impossible to polish the edges.
