Description

[0002] In the current climate of actively promoting energy conservation and emission reduction and striving to achieve the "dual carbon" goals, people are increasingly favoring a more environmentally friendly mode of transportation: electric vehicles. Electric vehicles, powered by power batteries, achieve zero emissions and pollution, and are the future direction and inevitable trend of automotive development. Currently, electric vehicle power batteries are typically built into a battery tray, consisting of multiple single-cell batteries connected in series. This results in a relatively heavy battery tray. Without securely welded lifting lugs, the battery tray could become loose and detach during driving, potentially causing an accident. Therefore, the weld strength of the lifting lugs significantly impacts the safety of electric vehicles.

[0003] In the existing field of lifting eye production, the production is generally carried out by the production workers manually holding the lifting eye structural parts to be welded for pre-assembly and then welding. Due to the different techniques of the production workers and the deformation of the lifting eye structural parts due to heat during welding, structural deformation is very easy to occur, which not only makes it impossible to ensure the welding quality, but also causes the installation position of the lifting eye after welding to move and cannot be smoothly connected with other structural parts, thus preventing normal use.
