Problems solved by technology

[0004] The other is the rear axle with connecting plate structure, which is generally used for the rear axle of miniature vehicles. Because the bearing hole and oil seal hole of the rear axle are not separated from the welded body, it is also affected by its rigidity, wall thickness, shape, size and complex accessories. Due to the influence of symmetrical welding and other factors, the components are easily deformed during welding and lose their performance. Therefore, the post-welding pro

Example Embodiment

[0032] The present invention will be described in detail below with specific embodiments. Here, the exemplary embodiments and description of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0033] The small deformation welding process for the rear axle housing assembly of the mini-vehicle provided in this embodiment includes welding of the middle section of the rear axle of the mini-vehicle, welding of the half-shaft sleeve assembly of the rear axle of the mini-vehicle, and welding of the rear axle housing of the mini-vehicle;

[0034] The welding process of the mid-section assembly of the rear axle of the mini-vehicle is as follows: firstly weld the longitudinal seams of the upper and lower half shells, and perform spot welding on the back cover and the reinforcement ring at the same time, and then weld the back cover and the reinforcement ring respectively, and after the welding, the reinforcement ring Make c...

Abstract

The invention discloses a small deformation welding process for a rear-axle housing of a mini vehicle, which belongs to the field of mechanical processing. The process comprises the welding of a middle segment assembly of a rear axle of the mini vehicle, the welding of a axle sleeve assembly of the rear axle of the min vehicle and the welding of the rear-axle housing assembly of the mini vehicle. The process has the advantages that: 1. a connecting disk is unnecessarily processed after being welded; 2. the welding order (welding unit) is reset for easy deformation control; 3. by adopting the rigid clipping welding, the product quality is ensured; and 4. compared with the prior art, the process has the advantages of few equipment, low process cost, low energy consumption, low processing cost, small manufacturing area, smooth logistics and high labor capacity.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to the processing technology of the rear axle housing. Background technique [0002] How to control the welding deformation of the rear axle housing and achieve the goal of no processing after welding has always been a hot topic in the field of rear axle housing manufacturing. There are two basic structures of the rear axle housing: [0003] One is the shaft head hub structure, which is generally adopted for the rear axle of heavy-duty vehicles. Because the rear axle of this structure has the characteristics of high rigidity, bearings, oil seal holes and welded components, the front and rear axle housings of this structure generally adopt welding. No post-welding processing technology, avoiding high post-welding processing costs, and reducing the process investment of large-scale processing equipment; [0004] The other is the rear axle with connecting plate structure, which i...
