A kind of automobile semi-shaft processing technology

Abstract

The invention relates to an automobile axle shaft machining technique. According to the automobile axle shaft machining technique, an automobile axle shaft is formed in a one-time mode through an automobile axle shaft numerical-control machining tool, time is saved, labor is saved, and the coaxality uniformity of axle shaft workpieces is improved. According to the automobile axle shaft machining technique, a clamping device is arranged in the middle of a lathe bed, clamping is carried out on the two sides at the same time, clamping rigidity is guaranteed, the workpieces can bear greater cutting force during turning, a left siding turning tool and a right sliding turning tool can machine a axle shaft workblank at the same time under the control of two independent digital-control systems respectively, therefore, multiple machining steps can be accomplished on one machine tool, the technique is simplified, working efficiency is improved, and technique accuracy and coaxality uniformity are also improved through the digital-control systems.

Description

technical field [0001] The invention relates to a processing technology of a mechanical component, in particular to a processing technology of 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 turning flange,...

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, high requirements for operators' skills, and due to multiple movements Half-axis workpieces cause a certain error or offset in the center position of each machining, resulting in a reduction in the precision of the formed half-axis, which will also reduce the service life of the half-axis
