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.

A method for welding an anti-rollover steel pipe of an automobile and an A-pillar reinforcement plate, wherein the A-pillar reinforcement plate includes an upper reinforcement plate and a lower reinforcement plate, the A-pillar reinforcement plate and the steel pipe are positioned by profiles, and there are certain gaps on both sides of the steel pipe and the upper reinforcement plate. Welding and manufacturing gaps, the lower reinforcement plate is in contact with the steel pipe on one side, and the steel pipe is welded to the A-pillar reinforcement plate under the condition that the other side is not in contact with the steel pipe. The welding method of the present invention has the following beneficial effects: the A-pillar reinforcement plate and the steel pipe are welded with a tolerance design, leaving a design gap between the two parts to ensure the manufacturing error and clamping error of the steel pipe (with curvature); the A-pillar steel pipe and the A-pillar The reinforcing plate is positioned by the profile, and the form of plug welding is adopted, the welding is stronger and meets the performance requirements of the whole vehicle; it can not only ensure the welding accuracy and assembly, so that the welding process can be realized, but also improve the welding strength of the steel pipe, and the welding is stronger .
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 solve the problem of minimizing occupant injury 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 auto...
