The Oil pump cover is one of the main part of automotive engine oil pump assembly .This paper expounds mainly about the machining technology and the design of clamping device of the oil pump. The precision of size, the precision of profile and the precision of Tolerance of position, of the oil pump is demanded highly , so arranging the craft course, need to separate the each main and superficial thick finish machining process. Reduce the function of processing the surplus , cutting force and internal stress progressively , revise the deformation after processing, can reach the specification requirement for the part finally .Accord technical economical analysis between precision design and technique of product structure of the design grip to catch the best economy effect.
