Abstract
Description
Technical Field

[0002] like Figure 4 and Figure 5 As shown, in the manufacturing process of the battery shell of a new energy vehicle, the frame 1 needs to be welded with the bottom plate 2, and 3 is a weld. Since the battery shell must be airtight, the stirring welding process is generally used during welding. The stirring welding is to rotate the stirring head at a high speed in the welding area. The high-speed rotation of the stirring head increases the temperature of the material, so that the material in the welding area is melted and mixed together. The advantages of stirring welding are fast welding speed, good welding quality, high welding stability, good airtight effect, no air leakage, and high joint strength after welding. The disadvantage is that the welding deformation is large. In the welding process of the frame 1 and the bottom plate 2, if the deformation of the stirring welding is not controlled, the flatness of the frame 1 after welding will change greatly, and often cannot meet the size requirements, resulting in a decrease in the yield rate, especially at the A and B positions shown in the figure, there are press riveting and pull riveting processes, and the plane is the plug-in panel. Here, the flatness requirements are controlled within 0.2 mm. In order to reduce the influence of stirring welding deformation and improve the yield rate, it is necessary to develop a stirring welding tool for the frame of a new energy battery shell that prevents welding deformation.
