Welding tool for welding lifting lug on battery tray

Abstract

The invention discloses a welding tool for welding a lifting lug on a battery tray. The welding tool comprises a pedestal; the center of the pedestal is provided with a machining region; any two adjacent sides of the machining region are each fixedly provided with at least two positioning blocks; each positioning block is used for positioning the battery tray; the other two sides of the machiningregion are each provided with at least one group of clamping mechanisms matched with the positioning blocks; at least two sides of the machining region are each fixedly provided with at least one group of pre-pressing mechanisms; a part, positioned at the circumferential side of the machining region, of the pedestal is also provided with a plurality of groups of final-pressing mechanisms; a plurality of clamping mechanisms are distributed in the circumferential direction of the machining region; and each clamping mechanism is used for clamping a to-be-welded lifting lug. The welding tool disclosed by the invention has the remarkable effects of realizing fixed positioning of the battery tray, also making the relative positions of the battery tray and the lifting lug be constant, improving the welding efficiency, also effectively guaranteeing the welding quality and improving the product quality.

Description

technical field [0001] The invention relates to the technical field of electric vehicle parts production, in particular to a welding tool for welding lifting lugs of battery trays. Background technique [0002] Electric vehicles use batteries as a power source and can achieve zero emissions and zero pollution, which is the direction and inevitable trend of the future development of automobiles. At present, the power battery used in electric vehicles is relatively heavy, generally about 60kg. If there is no good battery tray, the power battery may move during the driving of the car, causing an accident. The battery tray is connected and fixed through the lifting lug, so the connection strength between the battery tray and the lifting lug affects the stability of the battery tray and determines the quality of the electric vehicle. [0003] In the field of prior art, the welding of the battery tray and the lifting lug is generally carried out by the operator manually holding t...

Problems solved by technology

[0003] In the field of prior art, the welding of the battery tray and the lifting lug is generally carried out by the operator manually holding the lifting lug to be welded, but this method, due to the different strength of the operator, and the Under the action of force during welding, the lifting lugs are prone to shake or shake, which will obviously affect the product quality and welding processing efficiency of the lifting lugs to be welded, and even cause multiple lifting lugs to be not on the same installation plane so that the battery tray cannot work normally.
