[0053] The present application will be further explained in conjunction with the specific embodiments.

[0054] Please refer to Figures 1-9 The three-wheeled vehicle frame laser welding precision positioning equipment provided by the embodiment of the present application is mainly composed of a support box 1, a cover plate 2, a support plate 4, a support assembly, and a clamping assembly. The support box 1 is provided with support legs at the bottom, the cover plate 2 is in a mouth-shaped structure and is installed above the support box 1, and the support plate 4 is fixed on the support box 1. The support assembly is arranged between the support box 1 and the cover plate 2 and is used for supporting the main beam 14 and the cross beam 15. The clamping assembly is slidably installed on the support plate 4 by means of the telescopic cylinder 12 and can fix the metal template on the support assembly.

[0055] The support assembly includes ordinary support blocks 6, a multifunctional support block 25, knocking bars 20, and a support pipe 17. The ordinary support blocks 6 are provided in multiple groups, and the multifunctional support block 25 is provided in at least one group.
