Abstract
Description
Technical Field
[0001] This utility model relates to a carbon brush grinding processing device, belonging to the field of carbon brush processing technology. Background Technology
[0002] In the current field of carbon brush processing technology, carbon brushes, also known as electric brushes, are common components in electrical equipment. They are primarily made of carbon and a mixture of other materials, possessing good electrical conductivity and wear resistance. The shape and size of carbon brushes vary depending on the application, but they typically consist of a carbon block and a metal support. The carbon block is responsible for contacting the rotating contact surface, while the metal support provides fixation and support. During processing, its curved surface needs to be ground to improve its surface roughness.
[0003] Utility model patent CN213647073U discloses a motor carbon brush polishing device, including a worktable located at the bottom of a support frame. A clamping structure is located in the middle of the worktable, comprising a left clamping plate and a right clamping plate. The left clamping plate includes two parallel upper and lower vertical plates. A horizontal plate is fixedly connected to the bottom of the upper vertical plate and the top of the lower vertical plate. The left and right clamping plates are placed opposite each other. Vacuum cleaners are located on both sides of the clamping structure. A polishing machine is located above the clamping structure and is connected to a cylinder at the top of the support frame. A transparent glass cover is provided on the support frame. This application features a simple structure. The clamping device using this structure is simple, convenient, and quick. While polishing the carbon brush, it avoids powder flying everywhere and allows for clear observation of its operation.
[0004] However, the above solution has the following shortcomings in practical use: The above-mentioned device uses a clamping device to prevent powder from flying everywhere while grinding the carbon brush. However, in actual use, because the surface of the carbon brush has an arc shape, only one side can be ground. Furthermore, it is fixed by the clamping device, and only a single carbon brush can be processed at a time, resulting in low grinding efficiency. Utility Model Content
