A kind of numerical control processing method of automobile semi-shaft

Abstract

The invention relates to a numerical control machine tool for semi-axis of automobiles. A clamping device is arranged in the middle of the bed, and both sides are clamped at the same time, so that the clamping rigidity is ensured, so that the workpiece can be turned during the turning process. It bears greater cutting force, and two sets of independent numerical control systems control the left and right sliding turning devices to process the semi-axis blank at the same time. In this way, multiple processing steps can be carried out on one machine tool at the same time, which not only simplifies the process , the work efficiency is improved, and the process accuracy is also improved through the control of the numerical control system. At the same time, the machine tool uses the turning tool for processing, which reduces the cost compared with the milling tool used in the prior art.

Description

technical field [0001] The invention relates to a processing device for an automobile half shaft, in particular to a numerical control processing method 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 rough t...

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, it is necessary to make small head center holes, rough turn flanges and center holes, rough turn flange outer end faces, flange inner end faces, rough turn spline outer circles, and half shaft fixed lengths. 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.
