In order to solve the problems of poor quality consistency and low efficiency in the manual riveting of disc slip ring brush components，the research on the automatic riveting process was carried out， and the process scheme of radial automatic riveting was proposed.The drive platform and PLC control system were designed for the brush assembly products，and the operation process was supplemented by special assembly tooling，which could realize the automatic riveting of multiple groups of brush components.The process verification shows that the radial automatic riveting process can accurately ensure the deformation and appearance requirements of the brush assembly， greatly improve the product quality and work efficiency， and has been applied in model products.
