Description

TECHNICAL FIELD

[0001] The utility model belongs to diamond grinding brush field, especially relates to a diamond grinding brush convenient for replacing steel wire. BACKGROUND

[0002] In the process of diamond processing, the surface of diamond needs to be ground so that the surface of diamond can be smoother and more even. A grinding brush is a tool mainly used for diamond processing, which is mainly made by firmly fixing brush wires on a brush disc. The brush wires on the existing grinding brush for diamond processing are generally densely arranged on the brush disc. During use, the brush wires often cannot maintain the original hardness for a long time. After being used for a period of time during grinding, the brush wires are prone to spread apart, the grinding processing effect is poor, and the service life of the grinding brush is short. At present, most diamond grinding brushes are prepared by punching the brush wires and the brush disc with a punch press. Once the brush wires are damaged during use, the brush disc and the brush wires can only be replaced as a whole, the brush wires cannot be replaced individually, resources are wasted, and the use cost is high. Therefore, a diamond grinding brush convenient for replacing steel wire is needed.

[0003] A diamond grinding brush convenient for replacing steel wire is disclosed in Chinese Patent No. CN217071954U, which comprises a fixed disc. A brush disc mounting connecting hole is formed on the surface of the fixed disc, and a fixed ring is fixedly connected to the inner wall of the brush disc mounting connecting hole. The diamond grinding brush convenient for replacing steel wire is provided with a steel wire clamping and mounting mechanism. During use, the steel wire and the fixed disc are mounted through the clamping and mounting tube and the clamping and mounting hole, and the clamping and mounting tube is limitingly fixed through the connecting ring and the compression disc ring. After the brush wire of the grinding brush is damaged, the brush wire can be replaced by removing the connecting ring, the compression disc ring, and the clamping and mounting tube. Thus, the problem that the existing diamond grinding brush is prepared by punching the brush wire and the brush disc with a punch press, the brush disc and the brush wire can only be replaced as a whole once the brush wire is damaged during use, the brush wire cannot be replaced individually, resources are wasted, and the use cost is high is solved.

[0004] As known from the above structure, the steel wire clamping and mounting mechanism is provided. During use, the steel wire and the fixed disc are mounted through the clamping and mounting tube and the clamping and mounting hole, and the clamping and mounting tube is limitingly fixed through the connecting ring and the compression disc ring. After the brush wire of the grinding brush is damaged, the brush wire can be replaced by removing the connecting ring, the compression disc ring, and the clamping and mounting tube. Although the above structure can achieve the effect of disassembling the diamond grinding brush, the above structure directly replaces the entire diamond grinding brush during disassembly, which leads to waste of resources and increases the use cost of the diamond grinding brush. Therefore, a diamond grinding brush capable of replacing the steel wire according to the damaged part is proposed. SUMMARY
