Description

Technical Field

[0001] The utility model relates to the technical field of new energy battery shell manufacturing tooling, in particular to a new energy battery shell harness bracket welding tooling. Background Art

[0002] When manufacturing new energy vehicle battery shells, Figure 1 As shown, it is necessary to weld the wiring harness bracket 2 on the battery shell 1. The existing process requires manual welding, and it is necessary to use a measuring tool to measure and position it, and then the welder performs welding. The disadvantages of this welding operation are: 1. Manual measurement and positioning result in a relatively large position distance error, which directly affects the welding position accuracy; 2. The wiring harness bracket 2 is a structure with a round hole at one end and no round hole at the other end. The front and back sides are easy to be installed incorrectly, and manual distinction is required, and the reliability is not high; 3. The end face of the end of the wiring harness bracket 2 lacks effective positioning, which easily causes it to shift. The above problems are likely to cause a large difference in the relative position of the front side frame and the wiring harness bracket after welding, which ultimately leads to poor installation accuracy of the whole vehicle and causes module interference. In view of this, it is necessary to design a wiring harness bracket welding tool to further improve the welding quality of the wiring harness bracket and the front side frame. Utility Model Content
