Abstract
The invention relates to an axle housing assembly welding technique and a special clamp, belonging to welding machining technique and equipment field. A head seat 2 is connected with a tail seat 9 respectively through a guide rail and a machine body 1. An axle housing assembly balance-support device 5 and an axle housing assembly central positioning device 6 are connected with the machine body 1 through a connecting key. A support left-clamp body 3 and a support right-clamp body 8 are respectively connected through connecting keys with the head seat 2 and the tail seat 9. The support left-clamp body 3 and the support right-clamp body 8 are respectively connected with a hydraulic power device and a compressing device. The welding technique is that assembling is done first and point-welding is carried out for fixing, then the axle housing assembly is welded. In the welding process of the invention, a difference between the size between a round support and an axle housing body and the size of the drawings is preserved when in point-welding according to the distortion rule of welding, and after welding the size is eventually equal to that on the drawing through welding distortion.
