The utility model relates to the technical field of mechanical parts processing, in particular to a mechanical parts processing device.

Background technique

Mechanical parts are the basic components of machinery and are an inseparable part of the machine. In the production process of mechanical parts, a variety of processing devices are needed to process the mechanical parts. Among them, grinding devices are used to grind mechanical parts to make the surface of the mechanical parts smooth. At present, most grinding devices use two symmetrical clamps to clamp and fix the mechanical parts for grinding.

Preferably, a guide column is fixed inside the slide groove, and the moving block is slidably connected to the guide column.

Preferably, the sealing door is surrounded by sealing strips which are made of rubber.

Compared with the prior art, the beneficial effects of the utility model are as follows:

The utility model discloses a driving motor can drive the threaded column to rotate, and the threaded column can independently adjust the positions of the four clamping components. The spacing between the four clamping blocks can be adjusted during processing. Not only circular parts can be clamped, but also parts of different shapes can be applied, which is convenient for parts processing. It solves the problem that the four screws of the existing processing device can only drive the clamping blocks to move at the same time when clamping parts, so only circular parts can be clamped.
