Abstract

The invention relates to a machining method for an inner shell of a motor of a new energy vehicle. The machining method comprises the steps that after rough turning is conducted, a workpiece is heatedfor a certain period, after the workpiece is cooled to the room temperature, fine turning is conducted on the workpiece, the stress of the workpiece itself is eliminated, and the problem of workpiecequality instability is solved; each machine tool is provided with a water temperature cooler in the machining process, and the problem that the workpiece is unstable in quality due to the temperaturechange is solved; and a designed special fixture is used in the machining process, the problems of easy deformation and low concentricity in the workpiece machining process are solved, the qualification rate of the workpiece and the production efficiency of workpiece machining are greatly improved, and thus the production cost is saved.

Description

technical field [0001] The invention relates to the field of processing the inner casing of a new energy automobile motor, in particular to a processing method for the inner casing of a new energy automobile motor. Background technique [0002] For the processing of the inner shell of the motor, the conventional process first uses a horizontal lathe to support the inner hole of the workpiece with three claws, and then rough turns the outer diameter, and then uses the ring-shaped three-jaw clamp to turn the outer diameter, and then finishes the inner hole and inner groove, and then Use a three-jaw inner support to turn the inner hole, finish turning the outer diameter and outer groove, and finally use a vertical milling machine for milling. Because the inner shell of the new energy vehicle motor has the characteristics of thin wall and high material removal rate, the use of traditional fixtures will cause workpieces Deformation and concentricity are out of tolerance, which ca...
