Since the existing steel ring assembly welding equipment only has one station, when a steel ring assembly is processed, the processed steel ring assembly needs to be removed and then the steel ring assembly to be processed needs to be fixed on the station. The processing efficiency is low and the working interval of the welding mechanism is long.
