Battery module welding fixture

Abstract

The invention provides a battery module welding fixture. The battery module welding fixture comprises an installation plate, the installation plate is provided with an air cylinder, the part, around the air cylinder, of the installation plate is provided with guide sleeves, the guide sleeves are internally provided with connection columns in a penetrated manner, one ends of the connection columnsare connected with a first connection plate, the other ends of the connection columns are connected with a second connection plate, the first connection plate and the second connection plate are connected with the two ends of the air cylinder correspondingly, the second connection plate is provided with a fixture plate, the fixture plate is provided with a plurality of screw holes and detachable clamping seats and positioning plates, the clamping seats and the positioning plates are all provided with a plurality of fixing holes, the fixing holes are matched with the screw holes, the clamping seats are internally provided with concave arc mouths, the concave arc mouths between the clamping seats are oppositely arranged, the two sides of the fixture plate are provided with opposite grooves,and the grooves are internally provided with rotating plates. The battery module welding fixture adapts to the welding requirements for battery modules of different specifications, welding is made tobe accurate, and the welding cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of battery module production, and in particular relates to a welding jig for a battery module. Background technique [0002] The traditional welding fixture is to determine the fixture structure and press-fit method according to the size of the module. Each module can only use one kind of fixture, and the production line requires production efficiency. A line will make many fixtures according to the production cycle, and the clamping of the fixtures The position will not change due to the welding position. In this way, products of different specifications need to be pressed with fixtures of different specifications. After the production of the products is completed, the corresponding fixtures will also become waste products, and the cost is very high. And battery module welding usually requires precise welding. If the pressing position is wrong, welding will cause irreparable damage to the fixture. Conten...
