[0020] Preferably, the crossbeam fixing assembly 2 and the adaptive positioning fixture 3 have the same sliding path;

[0021] Preferably, the adaptive positioning fixture 3 includes a slide 31, a first hinge rod 32, a second hinge rod 33, a third hinge rod 34, a hinge bolt 35, a positioning bolt 4 and a clamping assembly 5. The bottom end of the slide 31 is slidably connected along the clamping table 1 through a slide groove 11. The top end of the slide 31 is hinged with a first hinge rod 32, the top end of the first hinge rod 32 is hinged with a second hinge rod 33, the top end of the second hinge rod 33 is hinged with a third hinge rod 34, and the third hinge rod A clamping assembly 5 for clamping the sheet metal bracket is provided at the top of 34, and a hinge bolt 35 for positioning is provided at the hinge of the first hinge rod 32, the second hinge rod 33 and the third hinge rod 34.

[0025] When welding instrument panel brackets of different models: first, place the tubular crossbeam on the clamping plates 23 in the crossbeam fixing assemblies 2 on both sides, then move the crossbeam fixing assemblies 2 on both sides so that the tubular crossbeam can be abutted against the limiting bosses on the outside of the clamping plates 23 for positioning, and then screw in the positioning bolts 4 at the bottom of the door-shaped frame 21 so that it abuts against the clamping table 1 for positioning;

[0027] The sheet metal support to be welded is installed in the clamping jaws 51 of the adaptive positioning fixture 3. The clamping direction can be changed by rotating the rotating column 52 at the bottom of the clamping jaws 51. The third hinge rod 34 is extended by rotating the shrink sleeve 53. During the extension process, the shrink sleeve 53 abuts against the clamping jaws 51 on both sides to force them to shrink inward, thereby clamping the sheet metal support. The clamping jaws 51 on both sides are squeezed when the shrink sleeve 53 abuts against them, so that the clamping direction cannot be changed by the rotating column 52 at the bottom.

[0028] By moving the adaptive positioning fixture 3 along the slide groove 11 on the end face of the slide table 31, the placement position of the sheet metal bracket in the axial direction of the tubular cross beam is changed. By changing the rotation angle of the first hinge rod 32, the second hinge rod 33 and the third hinge rod 34, the placement position of the sheet metal bracket in the radial direction of the tubular cross beam is changed. After the position adjustment is completed, the positioning bolt 4 on the end face of the slide table 31 is screwed in so that it is positioned against the clamping table 1. By tightening the hinge bolt 35, the first hinge rod 32, the second hinge rod 33 and the third hinge rod 34 cannot rotate, so that the sheet metal bracket is fixed at the welding position of the tubular cross beam axis.
