The first adjustment plate 2 is fixedly provided on the end of the support shaft 204, and a plurality of guide rollers 205 are rotatably provided on the side of the first adjustment plate 2 close to the skeleton vehicle suspension. By setting the guide rollers 205, the friction between the first adjustment plate 2 and the skeleton vehicle suspension is reduced, so that the second adjustment plate 3 can further push the skeleton vehicle suspension and further adjust its position.

[0038] A stabilizing rod 301 is slidably provided through the top of the welding table 1, and the second adjustment plate 3 is fixedly provided on the top of the stabilizing rod 301; a strip hole is provided through the top of the welding table 1, and the stabilizing rod 301 is square with the strip hole and slidably connected with the inner surface thereof; the second adjustment plate 3 is supported by the stabilizing rod 301, and the coordination of the stabilizing rod 301 and the strip hole effectively improves the stability of the second adjustment plate 3 during movement.

[0039] Among them, regarding the installation scheme of the stabilizing rod 301, a guide cylinder 302 is fixedly arranged between the welding table 1 and the installation frame 4, the stabilizing rod 301 penetrates the guide cylinder 302 and slides with its inner surface, and a moving bar hole is penetrated through the top of the guide cylinder 302, and the stabilizing rod 301 penetrates the moving bar hole and slides with its inner surface. Through the setting of the moving bar hole, a moving space is provided for the stabilizing rod 301, and its stability during the movement is improved; a connecting elastic member 303 is fixedly arranged between the stabilizing rod 301 and the inner wall of the guide cylinder 302, and the connecting elastic member 303 is a spring, and its elastic coefficient can be set according to demand. Through the setting of the connecting elastic member 303, when it is not subjected to external force, it can be driven to reset by the connecting elastic member 303.

[0040] A driving mechanism 5 is provided inside the welding table 1, wherein the driving mechanism 5 drives the connecting shaft 201 to rotate during the movement, thereby driving the first adjusting plate 2 to adjust the position of the left and right sides of the skeleton vehicle suspension through the connecting rod 202, and after the first adjusting plate 2 is squeezed with the side wall of the skeleton vehicle suspension, the second adjusting plate 3 is driven by the transmission structure 6 to approach the front and rear sides of the skeleton vehicle suspension.

[0041] Among them, regarding the design scheme of the transmission structure 6, the transmission structure 6 includes an air bag 601 fixedly arranged between the connecting block 203 and the first adjustment plate 2, and an air supply pipe 602 is connected between the air bag 601 and one side of the guide cylinder 302, and the air supply pipe 602 is a hose and passes through the side wall of the mounting frame 4; an extrusion block 603 is slidably arranged inside the guide cylinder 302, and the moving distance of the extrusion block 603 is less than the shortest distance between the extrusion block 603 and the side wall of the moving strip hole, so that there is always a sealed space between the extrusion block 603 and the guide cylinder 302; an extrusion rod 604 is fixedly arranged between the extrusion block 603 and the stabilizing rod 301. When the first adjustment plate 2 gradually approaches the frame vehicle suspension and contacts its side wall, since the first adjustment plate 2 is arranged on both sides of the frame vehicle suspension, both sides are evenly pushed by the first adjustment plate 2, and the first adjustment plate 2 continues to move. At this time, the position of the frame vehicle suspension is fixed and cannot move left and right, so that the first adjustment plate 2 moves along the inner surface of the connecting block 203 to the side away from the frame vehicle suspension through the support shaft 204, thereby squeezing the airbag 601, so that the gas in the airbag 601 enters the guide through the gas pipeline 602. Toward the cylinder 302, the air pressure in the guide cylinder 302 increases, thereby pushing the extrusion block 603 to move, so that the extrusion block 603 pushes the stabilizing bar 301 to move in the direction close to the skeleton vehicle suspension through the extrusion rod 604, and the stabilizing bar 301 drives the second adjustment plate 3 to move until the two second adjustment plates 3 push the skeleton vehicle suspension to the center position, the second adjustment plate 3 cannot move, and the gas in the airbag 601 can no longer be input into the guide cylinder 302. At this time, the first adjustment plate 2 and the second adjustment plate 3 clamp and fix the skeleton vehicle suspension.

[0043] As a further technical solution, a driving groove 505 is provided through the transmission rod 501, and a driving column 506 is rotatably provided on the outer surface of the driving shaft 502, and the outer surface of the driving column 506 is slidably provided with the inner surface of the driving groove 505. When the power member 504 is running, it drives the extension rod 503 to move to the side away from the welding table 1, and the extension rod 503 drives the driving shaft 502 to move. At this time, under the cooperation of the driving groove 505 and the driving column 506, the transmission rod 501 is pushed to drive the connecting shaft 201 to rotate, and the connecting shaft 201 drives the connecting rod 202 to rotate. The connecting rod 202 drives the first adjustment plate 2 to move toward the direction close to the frame vehicle suspension through the connecting block 203 and the support shaft 204, and the position of the frame vehicle suspension is adjusted and clamped.

[0044] As a further technical solution, a guide groove 507 is provided through the top of the mounting frame 4, wherein the drive shaft 502 passes through the guide groove 507 and is slidably arranged with the inner surface thereof.
