Fixture for mounting bracket assembly under the steering column of an automobile instrument panel crossbeam

Abstract

The invention relates to an assembly jig for the steering column lower mounting support of an automobile instrument board beam. The assembly jig comprises a support, wherein vertical plates are arranged on the left side and the right side of the support, lower baffles are arranged on the left side and the right side of the rear part of the support; a lower cylinder parallel to the upper end faces of the vertical plates and the vertical plates at the same time is arranged between the vertical plates, and a lower slideway is formed in the upper end face of each vertical plate; a lower sliding block sleeves each corresponding lower slideway; a lower guide plate parallel to the lower cylinder is arranged above each lower sliding block, and the upper end of each lower sliding block is connected with a lower flat plate; each lower guide plate penetrates through a groove formed in the lower part of the corresponding lower flat plate, the lower part of the front end of each lower flat plate is connected with the cylinder shaft of the lower cylinder in a hinged manner, and the lower end of each lower flat plate is propped against a lower baffle plate. The assembly jig has the advantages of reasonable structural design, convenient in adjustment, safe and stable in clamping, accurate in positioning and the like, and the various types of hole positioning columns and other structures ensure accurate clamping of the jig for an automobile instrument board beam assembly, so that the degree of deformation of the automobile instrument board beam assembly during the welding process is reduced.

Description

technical field [0001] The invention relates to the technical field of welding fixtures for automobiles, in particular to a fixture for mounting a bracket assembly under a steering column of an automobile instrument panel beam. Background technique [0002] Most of the auto parts are light and thin stamping parts, which are prone to deformation during welding. The installation of the deformed welded parts is difficult, which affects the overall performance of the car. The deformed welded parts generally need to be corrected. In order to improve the accuracy of the corrected shape, it is necessary to use The shape-correcting mold with higher precision and better rigidity will undoubtedly increase the production cost, prolong the production time, and reduce the production efficiency, and the stress and strain of the workpiece during the shape-correction are much more complicated than the general forming process. The effect is difficult to guarantee. [0003] The car dashboard...
