Rolling type automobile welding tool

Abstract

The invention discloses a rolling type automobile welding tool. The rolling type automobile welding tool comprises a base, the two ends of the base are fixedly provided with roller mechanisms, the roller mechanisms are provided with discs in a matching manner, a portion between the two discs is fixedly connected with a side wall clamping device which is clamped with an automobile body side wall and a top cover supporting device which is clamped with an automobile body top cover, the portion between the two discs is further fixedly connected with a fixed roller bed, the fixed roller bed is provided with a skid which is matched with an automobile body bottom plate in a limiting manner, and the fixed roller bed is provided with a skid drive device and a skid limit mechanism. The skid is matched with the automobile body bottom plate in a limiting manner, so that the skid and the automobile body bottom plate as a whole slide horizontally on the fixed roller bed to a welding position on thetool, the fixed roller bed limits and fixes the skid, and the side wall clamping device and the top cover supporting device respectively limit and fix the automobile body side wall and the automobilebody top cover. According to the rolling type automobile welding tool, the transportation mode of the welding mainline automobile body does not need to be changed, after the turnover operation is finished, the skid can always transport the automobile body on the production line along the horizontal track, so that the lifting and transportation process is saved and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of automobile production lines, in particular to a rolling type automobile welding tool. Background technique [0002] In the body welding process of heavy-duty vehicles or military vehicles, due to the high requirements for welding strength, double-sided CO 2 For gas shielded welding, the main line of the traditional automobile body-in-white production line is conveyed horizontally, and the body cannot be turned over. As a result, one side of some welds can only be welded in the overhead welding method, which is difficult to operate and prone to weld quality problems. [0003] Chinese patent CN203649739U discloses a 360 ° flip bulletproof car body welding tooling equipment, which fixes and clamps the car body through a reversible roller, and drives the roller to turn over through the driving device on the base. However, the welding tool can only allow the car body to be hoisted into the welding tool from t...

AI Technical Summary

Problems solved by technology

However, the welding tool can only allow the car body to be hoisted into the welding tool from the top by the crane, so when other production links are transported horizontally, the car needs to be transferred in this link, which affects the continuity of the entire automobile production line and efficiency
