Tooling and method for eliminating influence of welding deformation on pore diameter of opening portion

Abstract

The invention discloses a tooling and method for eliminating the influence of welding deformation on the pore diameter of the opening portion and aims to solve the problems existing in the prior art that because the wall thickness of the opening portion of an oil seal hole is smaller than or equal to 2 mm, a weld pass of a stabilizer bar support is welded in the circumferential direction of an oil storage cylinder, the oil seal hole seriously deforms after welding, furthermore, a spring disc adopts a press-fitting mode and is unstable and likely to loosen, and the oil storage cylinder at the expansion package position cracks. The tooling comprises a welding tooling and a shape righting tooling, wherein the welding tooling comprises a base and a fixing frame, the fixing frame is vertically arranged at the center of the base, a positioning disc is arranged on the fixing frame and is used for positioning the spring disc to facilitate welding, and after the spring disc is welded, the shape of the oil seal hole is corrected through the shape righting tooling. The purpose of the invention is that the press-fitting spring disc is changed into the welding spring disc, the welding deformation of the welding spring disc is ingeniously utilized to eliminate the influence of the welding deformation of the stabilizer bar support on the oil seal hole of the oil storage cylinder, and the risks of oil storage cylinder expansion package cracking and spring disc press-fitting loosening are avoided.

Description

technical field [0001] The invention belongs to the technical field of complete vehicle assembly, and in particular relates to a tool and a method for eliminating the influence of welding deformation on the mouth aperture. Background technique [0002] With the progress and development of the times, major automobile manufacturers have higher requirements for the automatic assembly of the whole vehicle, and higher requirements for the quality of each component product, so that the stability and size requirements for the shock absorber are stricter in all aspects; oil storage tank components It is one of the components of the shock absorber strut assembly. With the diversification of the structure of the shock absorber, the structure of the oil reservoir assembly is also diversified. [0003] In the prior art, the weld bead of the stabilizer bar bracket is required to be close to the oil seal orifice at a distance of ≤100mm, and the spring plate adopts a press-fitting method. ...

AI Technical Summary

Problems solved by technology

[0006] Due to the wall thickness of the oil seal orifice in the prior art is less than or equal to 2mm, the welding bead of the stabilizer bar bracket is welded along the circumferential direction of the oil storage cylinder. There may be looseness in the firmness, and there is a hidden danger of cracking in the oil storage tube at the expansion package. This invention proposes a tooling and method that eliminates the influence of welding deformation on the aperture of the mouth. Spring plate, the welding deformation of the welded spring plate is cleverly used to eliminate the influence of the welding deformation of the welded stabilizer bar bracket on the oil seal hole of the oil storage tube, avoiding the risk of cracking of the oil storage tube and the loosening of the spring plate
