Busbar sheet welding and fixing jig for aluminum shell battery cell

The utility model provides a Busbar sheet welding fixing jig for an aluminum shell battery cell, which comprises a clamping plate and a clamping tail handle, the clamping plate is used for clamping the aluminum shell battery cell and a Busbar sheet, the clamping plate is provided with a through hole, and the through hole corresponds to a pole of the aluminum shell battery cell; and the clamping tail handle is arranged on the outer side of the clamping plate and is used for controlling the opening and closing of the clamping plate so as to clamp the aluminum shell battery cell and the Busbar sheet. According to the Busbar sheet welding and fixing jig for the aluminum shell battery cell, bad influences caused by weak overcurrent capacity and Busbar sheet falling due to the fact that gaps exist between the Busbar sheet and the pole columns can be effectively prevented, material waste and test cost increase caused by disposable adhesive tape bonding are avoided, and meanwhile, the Busbar sheet welding and fixing
