Description

An automatic turning fixture for a grinding machine

technical field

The utility model relates to the technical field of grinder fixtures, in particular to an automatic turning fixture for grinders.

Background technique

A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinding machines use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools such as oil stones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machine tools, abrasive belt grinders, grinding machines and polishing machine etc. The grinding machine can process materials with higher hardness, such as hardened steel, hard alloy, etc.; it can also process brittle materials, such as glass and granite. The grinding machine can be used for grinding with high precision and small surface roughness, as well as high-efficiency grinding, such as powerful grinding.

When grinding the plate, it is necessary to fix the plate first before grinding. The existing plate grinding jig for grinding machines is cumbersome to operate. When the plate is repeatedly polished, it needs to be loaded and unloaded repeatedly, and the fixture cannot be used for plates of different sizes, and the scope of application is narrow. , for this purpose, we design an automatic turning fixture for grinding machines.
