Description

Polishing device for mechanical parts processing

technical field

The utility model belongs to the field of polishing devices, in particular to a polishing device for machining mechanical parts.

Background technique

Polishing refers to the use of mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and flat surface. Polishing cannot improve the dimensional accuracy or geometric shape accuracy of the workpiece, but to obtain a smooth surface or mirror surface The purpose of gloss is sometimes used to eliminate gloss, usually polishing tools are required for polishing.

There is an existing polishing device (CN217097192U) for processing mechanical parts. Using the cooperation of the load-bearing drive assembly and the limit assembly, the connecting block can move up and down on the front of the support plate, so that the height of the connection plate is different, and the two limit sleeves The distances from the drive shaft are also different, so that the position of cylindrical products of different sizes can be limited, thereby improving its practical performance. But the distance between the two limit sleeves of this device is fixed, and the cooperation between the two limit sleeves and the drive shaft utilizes the expansion force to fix the inner wall of the cylindrical product. Since the distance between the two limit sleeves is Fixing, for a cylinder with a smaller inner diameter, the expansion force can be evenly applied to the cylinder, and the fixing effect is ideal; once the inner diameter of the sleeve is larger, the expansion force will be uneven, and the fixing effect of the cylinder is not ideal. The polishing machine can only move horizontally, and the polishing machine cannot be adjusted up and down, because some parts have thicker rust or pollutants and need to be polished with special force, so the polishing machine needs to be precisely positioned to this part and polished separately.
