Embodiment Construction

[0013] As shown in the attached figure, the A-pillar reinforcement plate includes the upper reinforcement plate 2 and the lower reinforcement plate 3. In order to weld the anti-rollover steel pipe 1 of the automobile to the A-pillar reinforcement plate, the A-pillar reinforcement plate and the steel pipe are positioned to ensure their welding. Accuracy, the A-A section shows that there is a certain welding manufacturing gap between the steel pipe 1 and the upper reinforcement plate 2, and the back of the A-pillar reinforcement plate is provided with a plug welding port, and the back is in the form of plug welding. The B-B section shows that the lower reinforcement plate 3 is in contact with the steel pipe 1 on one side, and has no contact with the steel pipe 1 on the other side. The opening form is designed. At this time, the steel pipe is welded to the A-pillar reinforcement plate, which is beneficial to the steel pipe welding adjustment.

Abstract

The invention discloses a method for welding an automotive anti-rolling steel tube and an A column reinforcement plate. The A column reinforcement plate comprises an upper reinforcement plate and a lower reinforcement plate. The A column reinforcement plate and the steel tube are positioned by molding surfaces. A certain welding manufacture gap is formed between the steel tube and two sides of the upper reinforcement plate. One side of the lower reinforcement plate contacts the steel tube, and the steel tube is welded on the A column reinforcement plate under the condition that the other side of the lower reinforcement plate is not contacted with the steel tube. The welding method has the following advantages: a tolerance design is adopted for the welding between the A column reinforcement plate and the steel tube, so that a design gap is formed between the A column reinforcement plate and the steel tube, and a manufacturing error and a clamping error of the steel tube (with a curvature) are guaranteed; the A column steel tube and the A column reinforcement plate are positioned by the molding surfaces, the welding is more firm and the requirement on complete automobile performance is met due to a plug welding mode; the welding method can guarantee welding precision and assembly, realizes the welding technology, also can improve the welding strength of the steel tube and has more firm welding.

Description

technical field [0001] The invention relates to the field of automobile design, in particular to a welding method of an automobile anti-rollover steel pipe and an A-pillar reinforcement plate. Background technique [0002] When the existing steel pipe and the A-pillar reinforcement plate are welded, the gap between the steel pipe and the A-pillar reinforcement plate assembly is small or no. The requirements for welding precision are high, and the process cannot meet the requirements. Contents of the invention [0003] The purpose of the present invention is mainly to provide a welding method of an automobile anti-roll steel pipe and an A-pillar reinforcement plate, which is used to minimize the degree of injury to the occupants during the rollover simulation analysis of the current soft-top sports car. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A method for welding an anti-rollover steel pipe of an autom...
