Abstract

The invention relates to the technical field of welding process of thin-walled sheet metal parts, in particular to lithium battery box welding tooling, including a top cover cylinder welding tool; the top cover cylinder welding tool includes a top cover cylinder welding tool body, a fixed tire mold, and a sports tire Die and wedge-shaped tensioning mechanism; top cover cylinder welding tooling body includes beam, moving tire mold supporting plate, positioning key, moving tire mold pressing plate and first base; beam is fixed on the first base, moving tire mold supporting plate and positioning The key is set at the end of the beam, and the moving tire mold pressing plate is fixed on the top of the positioning key; the wedge-shaped tensioning mechanism is set in the middle of the beam; both the fixed tire mold and the moving tire mold are set The tightening mechanism is located between the fixed tire mold and the moving tire mold; the shape of the moving tire mold is the same as that of the fixed tire mold, and the center of the moving tire mold has a square stepped hole, and the cross section of the upper part of the square stepped hole is larger than the cross section of the lower part of the square stepped hole. The positioning key moves laterally in the lower part of the square step hole.

Description

technical field [0001] The invention relates to the technical field of welding technology of thin-walled sheet metal parts, in particular to a lithium battery box welding tool and a lithium battery box welding method. Background technique [0002] The lithium battery box is a closed structure of austenitic stainless steel, and a lithium battery core is installed inside it. The tools used to weld lithium battery boxes are called lithium battery box welding tools. For the existing lithium battery box welding tools, when using them to weld lithium battery boxes, there are problems of large welding deformation and poor battery volume consistency. . Contents of the invention [0003] In view of the above problems, the present invention is proposed to provide a lithium battery box welding tool and a lithium battery box welding method that overcome the above problems or at least partially solve the above problems. [0004] An embodiment of the present invention provides a lithi...
