Welding fixture for instrument panel beam attached part group

Abstract

The invention relates to a welding fixture for an instrument panel beam attached part group. The welding fixture comprises a base, wherein beam end part bracket assembly clamping devices are symmetrically mounted at the left end and the right end of the base, a first positioning clamping device is mounted in the middle of the base, positioning clamping racks are symmetrically mounted in the middle of the base, a second positioning clamping device is arranged in front of the positioning clamping rack positioned on the left side, a left reinforcing bracket positioning clamping device and an IP body positioning bracket assembly clamping device are arranged between the positioning clamping rack positioned on the right side and the first positioning clamping device, and a middle bracket assembly front end clamping device is arranged at the front end of the base. The welding fixture for the instrument panel beam attached part group has the advantages that the structural design is reasonable, the automation degree is high, and the control is convenient; the manual operation is replaced with automation, so that the efficiency of the positioning clamping is improved, and the welding precision is guaranteed; meanwhile, the self-positioning size can be adjusted, so that the welding fixture can adapt to the positioning clamping of the attached part group with different sizes and types, and the welding fixture has a wide application range.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a welding fixture for an instrument panel crossbeam accessory part set. Background technique [0002] As one of the important connecting parts of the car, the automobile instrument panel beam is used to fix the automobile instrument panel on the one hand, and on the other hand, it also increases the structural strength of the car itself. However, the structure of the automobile instrument panel beam itself is relatively complicated. It is processed by welding. When welding the crossbeam of the automobile dashboard, because there are many parts of the crossbeam of the automobile dashboard, in order to facilitate welding, it is necessary to divide the parts on it into different processes for tailor welding, which is also convenient for the clamping and positioning of the parts themselves, so as to ensure production The machining accuracy helps to improve the qualifie...

Problems solved by technology

[0004] For example, the Chinese patent ZL201020135982.2 proposes a welding fixture for an automobile instrument panel bracket, including a base mounting plate, two beam brackets for clamping the beam, and a large mounting bracket for clamping the end flange and the large and small mounting brackets Clamps, Mounting Bracket Clamps for Mounting Brackets, Retractor Bracket Clamps for Retractor Brackets, Steering Column Bracket Clamps for Steering Column Brackets, and Fuse box bracket fixture, each fixture is movably connected with the base mounting plate through its small base and the corresponding mounting hole on the base mounting plate, and its installation position corresponds to the welding position of the clamped workpiece and the beam, and each fixture is clamped by cylinder drive Action, the driving cylinder is connected with the electrical control system. The fixture can clamp and fix each bracket welded with the beam at the same time and cooperate with the welding machine for welding. It has reliable clamping, accurate positioning, easy loading and unloading of workpieces, and high work efficiency. Welding, however, the fixture cannot adjust its own positioning size for different part types, and the applicable surface is narrow. If the size of the corresponding part changes, the fixture cannot be clamped and positioned. At this time, the fixture needs to be adjusted. Correction is time-consuming and labor-intensive, which seriously affects the clamping efficiency of automobile instrument panel bracket welding
