Technical Field

[0001] The utility model relates to the technical field of automobile parts production tooling, in particular to an automobile parts laser welding tooling. The automobile parts laser welding tooling is a professional laser welding equipment, mainly used for the precise welding of automobile parts. Background Art

[0002] As major automakers continue to develop new models and the pace of vehicle replacement accelerates, manufacturers are placing increasingly higher demands on the quality of auto parts. However, some products experience quality issues such as batch part deformation during production, which cannot be effectively addressed during the production process. Consequently, welding tooling is the only solution.

[0003] As quality costs continue to rise, traditional tooling lacks cooling devices, which prevents effective cooling after laser welding and makes repair difficult during subsequent production. To save labor and material costs, improve production efficiency and first-time pass rates, a new laser welding tooling system is urgently needed. Summary of the Invention

[0004] The purpose of this utility model is to provide a laser welding tool for automobile parts to solve the above problems.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a laser welding tool for automobile parts, comprising a first pressure arm and a second pressure arm arranged symmetrically on the left and right, and a first cylinder and a second cylinder are connected to the outer ends of the first pressure arm and the second pressure arm respectively; a profiling block, a support block and a first support seat are arranged in sequence at the lower end of the first pressure arm, and a profiling block, a support block and a second support seat are arranged in sequence at the lower end of the second pressure arm, wherein the number of profiling blocks at the lower end of the first pressure arm and the number of profiling blocks at the lower end of the second pressure arm are both at least six, the upper end of each profiling block is flush, and the lower end fits with the upper end of the support block, there are at least three support blocks under the first pressure arm and the supporting copper blocks under the second pressure arm, the lower end of each support block is flush, and an air pipe joint is arranged on the side of each support block, and at least two air outlet holes communicating with the air pipe joint are arranged on the contact surface between the upper end of each support block and the profiling block.

[0006] The utility model provides an air outlet on the cooling tooling below the part, and blows cold air to the air outlet through an air cooler, which serves as a real-time cooling device to cool the part in real time and reduce deformation.

[0007] As a preferred technical solution, the number of the shaping blocks at the lower end of the first pressing arm and the number of the shaping blocks at the lower end of the second pressing arm are both eleven, and there are four support blocks under the first pressing arm and four support blocks under the second pressing arm, and the upper ends of the two support blocks at both ends are provided with steps.

[0008] As a preferred technical solution, the profiling block is a profiling copper block, and the supporting block is a supporting copper block.

[0009] Compared with the existing technology, the advantages of the present invention are: the tooling of the present invention realizes efficient welding and improves product consistency through the profile and cooling structure formed by multiple profiling blocks, and has small welding deformation, and does not require subsequent shaping and polishing treatment, which can significantly improve welding quality and production efficiency. Traditional laser welding fixtures have no cooling, and the deformation of parts after welding is about 0.2-0.5mm. However, with the structure of the present invention, the deformation of parts after welding is about 0-0.15mm. BRIEF DESCRIPTION OF THE DRAWINGS
