The invention provides a torsion beam rear axle welding process. The torsion beam rear axle welding process comprises the following steps: (S1) a left suspension arm welding assembly, a right suspension arm welding assembly and a cross beam welding assembly are manufactured; (S2) the left suspension arm welding assembly and the right suspension arm welding assembly are symmetrically welded at two ends of the cross beam welding assembly; (S3) a left spring disc and a right spring disc are welded; a left hose bracket and a right hose bracket are welded; and a left harness bracket and a right harness bracket are welded to form a torsion beam rear axle assembly frame; (S4) a left vibration reducer bracket and a right vibration reducer bracket are welded; and (S5) a left suspension arm and a right suspension arm are respectively welded with two sleeves to form a torsion beam rear axle welding assembly. The torsion beam rear axle welding process releases the welding deformation through multiple branch assembly procedures, reduces the influence on separation size of the sleeves, can control the sleeve size tolerance within +-0.8 mm, and improves the product size precision.
Description
technical field [0001] The invention relates to a welding process, in particular to a torsion beam rear bridge welding process. Background technique [0002] figure 1 It is a structural schematic diagram of a torsion beam rear axle in the prior art. figure 2 It is a schematic diagram of the welding seam between the flange plate and the suspension arm in the torsion beam rear axle in the prior art. image 3 It is a schematic diagram of the welding seam between the suspension arm and the casing in the later stage of the torsion beam in the prior art. [0003] Such as Figure 1 to Figure 3 As shown, the welding process of the torsion beam rear bridge is usually that the suspension arm (left and right) 10 is welded with the flange plate 11 and the sleeve 12 to form the suspension arm subassembly (left and right), and then the frame is assembled with the beam 13. Then assemble and weld the spring disc, brake hose bracket and shock absorber bracket. [0004] However, the cur...
