Abstract
In response to the practical requirements of high geometric accuracy and good quality stability in the machining of the motor case of new energy vehicles,this paper analyzes the structural characteristics of the shell parts,designs corresponding CNC machining processes and reasonable terminal clamping methods,and develops a special core expanding fixture.Through static and dynamic finite element analy-sis,as well as clamping force calculation and verification,it can meet the practical requirements and has been successfully applied in the pro-duction factory.The results show that the machining process route and the use of the expansion sleeve fixture have good effects,which can achieve the goal of efficient and precise machining of the motor case of new energy vehicles.
