Abstract: The material and structural analysis of the sleeve, the six party on the edge size precision and roughness of the processing difficulty. Making process is reasonable and feasible. In the rough, semi-refined car after cutting out in six sides and small amount of allowance, design precision push knife cut in six dimensions, the positioning core inscribed circle in precision turning, and the design of elastic turning end face and the inner groove, ensure parts processing to meet the requirements of the drawings
Key words:motor car;electrical connector;shaft sleeve
