[0024] In this embodiment, the base 1, the pressing component 2 and the pre-positioning component 3 constitute the main structure of the anti-deformation structure of the positioning welding fixture of metal products involved in this application, and the metal product is set as a steel frame structure.

[0025] Specifically, rubber pads are provided on the opposite sides of the limiting block 11 and the clamping block 12 to realize the clamping and holding of the bottom of the steel frame.

[0026] As Figure 2 and Figure 3 shown, the pressing block component 26 includes a hollow block 261, a cavity 262 is opened on the lower side of the hollow block 261, and a spring 263 is installed in the cavity 262. The lower end of the hollow block 261 is connected to an elastic plate 264, and a buffer pad 265 is connected to the lower end of the elastic plate 264, and the elastic plate 264 is connected to the lower end of the spring 263.
