Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, in particular to a frame assembly welding tooling. Background Art

[0002] The battery pack shell frame assembly of new energy vehicles is made by welding metal materials. Currently, welding tooling is required when welding it.

[0003] The frame assembly includes two side brackets and two end brackets. The two ends of the end brackets are welded to the side brackets respectively. The side brackets and the end brackets form a rectangular frame. Two horizontal braces are welded in the rectangular frame. A longitudinal brace is welded between the two horizontal braces and between the horizontal brace and the end bracket. A long brace is welded between the longitudinal brace and the side bracket. A short brace is welded between the long brace and the end bracket. Four short braces are welded between the horizontal brace away from the long brace and the end bracket. During the processing of the frame assembly, the welding position needs to be welded, so welding tooling is needed to clamp and fix the side brackets, end brackets, horizontal braces, longitudinal braces, long braces and short braces.

[0004] The welding tooling currently used for welding the frame assembly includes a tooling base plate, on which a plurality of support seats and positioning seats are fixedly installed. After the frame assembly is placed on the support seats, the positioning seats are used to position the frame assembly, and then the frame assembly is pressed onto the tooling base plate by means of press clamps. However, during the entire process, multiple press clamps are required, and the operator is required to walk around the tooling base plate and manually rotate all the press clamps, which is time-consuming and inefficient.

[0027] like Figure 1-8 As shown, a frame assembly welding tool comprises a base 1, on which a bottom plate 2 is fixedly mounted.
