Numerical control processing machine tool of automobile half shaft

Abstract

The invention relates to a numerical control processing machine tool of an automobile half shaft. The numerical control processing machine tool has the characteristics that a clamping device is arranged at the middle part of a tool body, and the two edges are clamped simultaneously, so that the clamping rigidity is guaranteed, and further a workpiece can bear larger cutting force in the turning processing process; a left sliding turning device and a right sliding turning device are respectively controlled by two sets of independent numerical control systems to process a half shaft blank, so that multiple processing steps can be carried out on one machine tool simultaneously, and not only is the process is simplified, but also the working efficiency is improved; by control of a numerical control system, the accuracy of the process is also improved; simultaneously the machine tool adopts a turning tool for processing. Compared with the prior art adopting a milling cutter, the numerical control processing machine tool of the automobile half shaft has the advantage that the cost is reduced.

Description

technical field [0001] The invention relates to a processing device for an automobile half shaft, in particular to a numerical control processing machine tool for an automobile half shaft. Background technique [0002] In the design and manufacture of automobiles, the automobile half shaft is an important part of the automobile transmission system. The half shaft is used to transmit the power output by the differential half shaft gear to the driving wheel or the wheel reducer. According to the stress on the inner and outer ends of the half-shaft, the driving axle of the type suspension is usually divided into three types: semi-floating half-shaft, three-quarter floating half-shaft and full-floating half-shaft. The manufacturing process of the axle shaft is very delicate and involves many steps. [0003] At present, in the industry of producing automobile half shafts, the center hole of the small head, the rough turning flange and the center hole, the outer end face of the r...

The manufacturing process of the axle shaft is very delicate and has many steps

[0003] At present, in the industry of producing automobile half shafts, the center hole of the small head, the rough turning flange and the center hole, the outer end face of the rough turning flange, the inner end face of the flange, the outer circle of the rough turning spline, and the fixed length of the half shaft are all A single processing technology, using multiple drilling machines and ordinary lathes for manual processing of multiple handling and clamping; resulting in low production efficiency, high labor costs, unguaranteed product quality, and high skill requirements for operators. Since the general half shaft is processed by milling cutters, the cost of milling cutters is high, and the processing time is long, resulting in low production efficiency, making it difficult to adapt to the increasingly fierce competition in the auto parts industry, and will eventually be eliminated.
