Problems solved by technology

Due to the limitation of product design structure and fixture positioning mechanism, it is generally difficult to weld the rear taillight mounting plate and the outer panel of the trunk lid
And it is easy to produce bad defects such as welding distortion due to welding difficulties
[0005] However, when using CO2 gas shielded welding, it is more difficult to grind the welding bump, and the appearance quality after grinding is poor.
[0006] Therefore, it is necessary to provide a new mechanism to solve the problem of welding difficulties caused by the influence of the fixture positioning mechanism

Abstract

Disclosed is a trunk lid welding structure. According to the trunk lid welding structure, a welding tongs part, a clamping part and a copper bar part are installed on a clamp body, the clamping part is electrically connected with the welding tongs part through a clamped portion of a plate to be welded, a welding point is formed on the clamped portion through electrical connection to achieve welding connection of the plate to be welded, the clamping part also serves as a contact for electrical welding, and accurate positioning and accurate contact matching are guaranteed during welding.

Description

technical field [0001] The invention relates to a welded structure, in particular to a welded structure for a trunk lid of an automobile. Background technique [0002] Among the three-box sedans, many split taillights are used, that is, part of the taillights are arranged on the side wall, and the other part of the taillights are arranged on the trunk lid. This kind of taillight arranged on the trunk lid generally needs to design a separate taillight mounting plate due to factors such as shape and taillight arrangement; the rear taillight mounting plate is then connected to the outer panel of the trunk. [0003] The connection between the existing rear taillight mounting plate and the trunk outer panel generally adopts the common spot welding method of common clamps. There are also CO2 gas shielded welding that is not accessible due to structural limitations. [0004] Ordinary spot welding with ordinary fixture, the fixture adopts steel structure, welding tongs use ordinar...
