Abstract

The invention discloses a welding positioning tool of a battery box body of an electric automobile. The tool comprises a bottom plate and a box body inner cavity limiting plate fixedly arranged on the bottom plate, wherein a plurality of connecting seat bases corresponding to connecting seats on the battery box body in position in a one-to-one mode are arranged on the bottom plate, and a lifting driving mechanism is arranged on each connecting seat base. The tool is characterized in that a box body side wall outward supporting mechanism is arranged on the bottom plate, and has the advantages that due to the fact that the box body side wall outward supporting mechanism is arranged on the bottom plate, before the connecting seats are welded, the side walls of the battery box body are supported outwards through the box body side wall outward supporting mechanism, the welding deformation of the side walls is reduced, the welding quality between the connecting seats and the side walls of the box body is improved, and the connecting strength of the battery box body is guaranteed.

Description

technical field [0001] The invention relates to processing equipment for battery boxes of electric vehicles, in particular to a welding and positioning tool for battery boxes of electric vehicles. Background technique [0002] The battery box of an electric vehicle is generally composed of an upper box and a lower box, and the upper box and the lower box are generally welded with reinforcing ribs and a plurality of connecting seats, through which the upper box and the lower box can be connected. The body is connected and fixed with each other, and the strength of the box can be enhanced by reinforcing ribs. At present, when the battery box is welded, the reinforcing rib and the connecting seat are directly welded to the bottom surface and the side wall of the box after the box is positioned. However, due to the thin thickness of the box, the side wall is prone to deformation. As a result, the welding between the connecting seat and the side wall of the box body is uneven, a...
