Description

Technical Field

[0001] The utility model relates to the technical field of welding auxiliary equipment, in particular to a welding tool for a battery rack of a new energy vehicle. Background Art

[0002] Energy vehicle batteries can be divided into two categories: storage batteries and fuel cells. New energy vehicle battery packs consist of multiple cells stacked in series. A typical battery pack has approximately 96 cells. For lithium-ion batteries charged to 4.2V, such a battery pack can produce a total voltage of over 400V.

[0003] When installing batteries for new energy vehicles, the batteries need to be installed neatly on the battery rack. Since the positions between the batteries need to be precisely arranged, the structural stability of the car battery places high demands on the battery rack structure. When producing the battery rack, it is necessary to ensure that the connection between the battery rack structures is firm. Welding is often used to improve the firmness of the connection. In order to facilitate the placement of the car battery, the battery rack itself adopts a grid-like structure. When welding, the joints between the grids need to be welded. The traditional single-position welding method will cause the next welding position to deform after the welding of the previous position is completed. After the overall structure is welded, the deformation is visible to the naked eye, causing the placement position of the car battery to shift, affecting the normal operation of the car battery.

[0004] For example, a battery rack welding tool with publication number CN219598563U includes a main body, a fixing mechanism and a support mechanism, wherein a fixing mechanism is provided at the top of the main body, and a support mechanism is provided at the top of the fixing mechanism. The main body can provide stable support and a solid processing environment for the welding tool, and the fixing mechanism can provide a stable and easy-to-place processing platform for the support mechanism, which is convenient for the user to assemble the welding tool, improve the multi-point stable support of the welding tool, and enhance the overall stability of the welding process. The support mechanism can be used to perform multi-point positioning and fixed limit on the processed battery rack, so that the battery rack is not easily displaced during the processing process. At the same time, the support mechanism is highly flexible and easy to adjust, and can adapt to more types and models of battery racks for processing, reducing the production cost of traditional battery rack welding tools and improving the market competitiveness of this battery rack.

[0005] In actual application of the above technical solution, there is a problem that deformation occurs inside the battery rack during welding.

[0006] Therefore, it is necessary to invent a welding tool for a new energy vehicle battery rack to solve the above problems. Utility Model Content
