This utility model relates to the field of metal surface treatment technology, specifically to a cleaning device for grinding bearing steel balls. It includes a sealed base, with a mesh frame installed on the upper part of the sealed base. A transmission pipe for transporting steel balls is connected to the upper rear of the mesh frame. The portion of the transmission pipe that penetrates the sealed base is a through-hole, and this through-hole is designed at an angle. A discharge port is opened in the lower part of the mesh frame, and a cleaning brush assembly is installed inside the mesh frame. By combining the cleaning brush assembly with an ultrasonic isolation chamber, the abrasive and metal debris on the surface of the steel balls are thoroughly removed. The vortex-like motion of the brush rollers, combined with the solution sprayed from the high-pressure nozzle, effectively removes larger particles of contaminants, while the cavitation effect generated by the ultrasound further removes microscopic contaminants. The angled design of the transmission pipe ensures that the steel balls are evenly distributed when entering the mesh frame, avoiding accumulation and thus improving cleaning efficiency. An electric push rod and a baffle can precisely control the discharge process of the steel balls when needed.
