[0001] The utility model relates to the technical field of fixing devices, in particular to a fixing device for grinding graphite parts. Background Art

[0002] Graphite parts refer to parts made of graphite. Graphite is a mineral composed of carbon atoms, which has good electrical conductivity, thermal conductivity, high temperature resistance and chemical stability. In industry and manufacturing, graphite is widely used to produce various types of parts, such as electrodes, bearings, gaskets, seals, molds and lubricating materials. Nowadays, during the production process of stone mill parts, they need to be limited by fixing devices and ground with grinding equipment to make them into stone mill parts of qualified size for use.

[0003] However, the existing fixing devices usually fix a relatively single type. Among them, the cylindrical stone mill material is difficult to clamp and position due to the curved surface design. If a material specially used to fix cylindrical stone mill parts is used, it will be difficult to clamp plate-shaped stone mill parts. In view of this, we propose a fixing device for graphite part grinding. Utility Model Content
