Top cover and side wall welding assembly structure

Abstract

The invention discloses a welding assembly structure of a top cover and a side wall, comprising six parts: a top cover, a luggage installation bracket, a side wall outer panel, an upper reinforcement plate on a front column, an edge beam on an inner panel of a center column, and an upper inner panel on a front column , the top cover is provided with a sunroof reinforcement ring, and the edge of the reinforcement ring is provided with a welding block, the welding block is located between the connection part of the top cover and the connection part of the side wall outer panel, and the connection part of the inner panel on the front pillar is provided with The first plug welding hole, the reinforcement plate on the front column is provided with a welding block installation groove corresponding to the welding block, and the second plug welding hole is provided on the installation groove, and the reinforcement plate on the front column is provided with a third plug welding hole corresponding to the first plug welding hole The connection part of the side beam on the inner panel of the center column corresponds to the second plug welding hole and has a gap. The welding assembly structure of the top cover and the side wall of the present invention solves the problems of weak solder joints, prone to false welds, excessively large solder joint spacing, difficult welding operations, and inconvenient grinding when spot welding is used, and effectively improves performance and modality of the body-in-white.

Description

technical field [0001] The invention belongs to the technical field of vehicle body installation, and in particular relates to a welding assembly structure of a top cover and a side wall. Background technique [0002] At present, when a car with a luggage rack is installed with a luggage rack mounting bracket structure, the number of sheet metal layers at the overlap between the roof welding assembly and the side wall welding assembly and the bracket is relatively large, and there may be five-layer or six-layer boards. The current automobile mainly adopts two kinds of welding methods for welding: [0003] 1. The traditional spot welding of the inner panel is used. This method is prone to weak welding, false welding, and weak welding, which will affect the performance and mode of the body-in-white. [0004] 2. Secondary welding is used. After the welding of the car body is completed, the luggage rack mounting bracket is welded by secondary welding. This method has high requi...
