Embodiment Construction

[0022] In order to make the present invention clearer, the device will be described in detail below in conjunction with the accompanying drawings. The specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0023] like figure 1 , figure 2 and image 3 As shown, a kind of welding method of rear drive axle housing assembly provided by the present invention, with respect to arc welding adopted in the prior art, this method adopts friction welding, is characterized in that comprising the following steps:

[0024] a. First process the semi-shaft sleeve 3 from the rough into a finished product, that is, firstly rough the blank 3a of the half-shaft sleeve 3, and then carry out the finish turning to process the bearing neck 3c with a stepped structure. Rough turning and finishing turning are both conventional processing methods, and then the keyway is milled on a milling machine to process the keywa...

Abstract

The invention relates to a welding method of the rear drive axle housing assembly, which comprises the following steps: a. Processing the blank (3a) of the half-shaft sleeve (3), roughing and finishing the bearing neck of the stepped structure (3c), and then mill the keyway to process the keyway to form the finished part (3b) of the half shaft sleeve (3); b, the finished part (3b) and the axle housing body (1) are correspondingly matched on the friction welding machine; c . Weld the axle casing (3) and the axle housing body (1) by a special friction welding machine. Advantages of the present invention: the welding efficiency of this method is higher than that of the existing arc welding process, material is saved, labor intensity is significantly reduced, arc radiation is not generated during the welding process, and there is no smoke, so that the working environment has been significantly improved, and its welding quality is stable. The risk of weld fracture at the casing is reduced, the processing cost is low, electricity is saved, mechanization and automation are easy to realize, the operation is simple, and there is no spark, arc light and harmful gas in the welding work site.

Description

technical field [0001] The invention relates to the technical field of rear drive axle housings, in particular to a welding method for a rear drive axle housing assembly. Background technique [0002] The car rear axle shell is one of the important parts of the car rear axle shell. The rear drive axle is at the end of the power transmission system. Its basic function is to increase the torque transmitted by the drive shaft or transmission and distribute the power reasonably. For the left and right drive wheels, it also bears the vertical, longitudinal and lateral forces acting between the road surface and the frame or body. The drive axle is generally composed of the final drive, differential, wheel drive and drive axle housing. [0003] With the development of my country's automobile manufacturing industry and the continuous expansion of production scale, the requirements for welding technology are getting higher and higher. Traditional manual arc welding is gradually repl...
