[0002] A grinder is a mechanical device used to grind, polish or cut workpieces. They usually use rotating grinding wheels, abrasive belts or other grinding tools to achieve the processing of the workpiece surface. They are usually used to process metal, glass, ceramics, plastics and other materials to improve the accuracy, finish and shape of the workpiece surface. The principle is to use abrasive tools (such as grinding wheels) to grind the workpiece surface. It is widely used in metal processing, woodworking, glass processing, ceramic processing and other industries, as well as parts processing, surface treatment and other fields in the manufacturing industry.

[0003] Equipment for high-precision surface grinding is usually called high-precision surface grinders. These machines are specially designed for precision grinding of flat workpieces to obtain very flat and precise surfaces. They are usually widely used in industries that require high-precision surface processing, such as aerospace, automobile manufacturing, mold manufacturing, etc. They can provide very flat and precise surfaces to meet the needs of high-precision parts processing. However, at present, the workpiece placement of grinders in China is done manually, which generally occupies human resources, is time-consuming and labor-intensive, and leads to slow production efficiency. For this reason, we propose a workpiece placement device for grinders to solve the above problems. Utility Model Content
