Abstract

The invention discloses a machining method for a slender shaft of an automobile motor. The method comprises the following steps that a center frame is directly supported in the middle of a workpiece, lubricating oil should be frequently added at the contact part of a supporting claw of the center frame and the workpiece during turning, a layer of gauze and a grinding agent are added between the supporting claw and the workpiece for grinding and cohesion, the thermal deformation elongation of the workpiece is calculated through a calculation formula, then, a turning tool is reasonably selected, radial cutting force is reduced, the tool cutting edge angle of the turning tool is 90-93 degrees, the cutting force and cutting heat are reduced, a larger front angle of 20-25 degrees is selected, an R1.5-3 chip breaker groove is ground in the front of the turning tool, cuttings are curled and broken, a positive edge inclination angle is selected, lambda is equal to 3, cutting allowance flows to the surface to be machined, and the curling and cutting effect is good. The problems that in the cutting process, the workpiece is bent and deformed when heated, even the workpiece is clamped between the tips and cannot be machined, the workpiece is bent under the action of cutting force, and therefore vibration is caused, and the precision and the surface roughness of the workpiece are affected are solved.

Description

technical field [0001] The invention relates to the technical field of slender shafts of automobile motors, in particular to a processing method for slender shafts of automobile motors. Background technique [0002] The slender shaft is the most difficult part to machine in machine tool machining. In the past, there was a saying in the machining industry: "Turners are afraid of the poles, and fitters are afraid of bruising their eyes." By "rod" is meant an elongated shaft. "Eye" refers to a hole. In fact, this sentence is not outdated now. The slender shaft has always been a technical problem in machine tool processing. During the cutting process, the workpiece will be bent and deformed when heated, and even the workpiece will be stuck between the tips and cannot be processed. The workpiece is bent by the cutting force, thus The vibration will affect the precision and surface roughness of the workpiece, so we design a processing method for the slender shaft of the automo...
