A battery frame multi-station welding tooling assembly

Abstract

This invention discloses a multi-station welding fixture assembly for battery frames, including a welding table. A first clamping mechanism and a second clamping mechanism are respectively arranged at both ends of one side of the welding table, and a third clamping mechanism and a fourth clamping mechanism are respectively arranged at both ends of the side of the welding table away from the first and second clamping mechanisms. This invention utilizes the cooperation of the first, second, third, fourth, and fifth clamping mechanisms to sequentially clamp the various parts of the battery frame. This ensures precise assembly of each welding point of the frame and provides a firm grip, preventing displacement during welding. This results in higher precision of the welded product. By using a multi-station welding fixture unit to limit, fix, and weld multiple parts of the battery frame separately, it overcomes the problem of traditional welding methods requiring multiple separate welding fixtures and processes, significantly reducing welding costs.

Description

Technical Field

[0001] The invention relates to the field of battery frames, and in particular to a multi-station welding tooling group for battery frames. Background Art

[0002] With the world's energy shortage and environmental protection requirements, cars powered by gasoline and diesel have been subject to certain restrictions and impacts. Environmentally friendly and energy-saving electric vehicles have become an important branch of the automotive industry. Electric vehicles just meet the dual requirements of energy and environmental protection. The key component of electric vehicles is the battery. The battery is assembled into a battery frame, and the battery frame is fixed to the chassis of the electric vehicle for use. The battery frame is produced by welding multiple components together. Therefore, during processing, it is necessary to use welding tools to clamp the workpiece and then use auxiliary welding devices for welding.
