Abstract

A positioning device of a welding fixture for a rear main pipe comprises a fixture assembly bottom plate, wherein a plurality of rear main pipe limiting pedestals used for limiting the rear main pipe, fast pressing clamps used for fixing a welding component and fast clips used for limiting the welding component are mounted on the fixture surface of the fixture assembly bottom plate. The rear main pipe limiting pedestals are divided into two symmetrical groups, wherein a first seat cushion lock bed mounting bracket assembly positioning seat and an oil tank front mounting bracket assembly positioning seat are arranged between the two groups of the rear main pipe limiting pedestals and located on the fixture assembly bottom plate. Positioning pins are mounted both on the upper surface of the first seat cushion lock bed mounting bracket assembly positioning seat and on the upper surface of the oil tank front mounting bracket assembly positioning seat and can play a positioning role for the welding component. Limiting pins used for limiting a rear shock absorber mounting bracket assembly are mounted at the front end of a first fast clip and at the front end of a second fast clip. Due to the fact that the welding component is positioned and limited, the welding component can be positioned accurately and cannot move easily, welding can be carried out conveniently after the welding component is positioned accurately, and the finished product rate of products is improved.

Description

technical field [0001] The invention relates to a positioning device, in particular to a positioning device for a rear main pipe welding tool. Background technique [0002] The rear main pipe used on the vehicle needs to be welded with a connecting piece (ie, a weldment) before it can be assembled on the vehicle for use. In the prior art, when the connecting piece is welded to the lower connecting pipe, a positioning and fixing device is required, which can accurately realize the positioning between the lower connecting pipe and the connecting piece, and is convenient for welding. [0003] However, the existing positioning device of the rear main welding tool will be displaced after the positioned lower connecting pipe or connector due to external force, resulting in inaccurate and reliable positioning, resulting in large errors in welded products and a high rate of defective products. Contents of the invention [0004] In view of the above technical problems, the present...
