The support frame 2 is equipped with a first motor 5 and a first gear 6, and the support base 3 is equipped with a second gear 7 that meshes with the first gear 6. The clamping device includes a moving plate 8, a moving cylinder 9 on the moving plate 8, and clamping frames 10 on both the output end of the moving cylinder 9 and the welding table 1. A vacuum pump 11 is provided on one side of the clamping frame 10, and a vacuum hose 12 is provided on the vacuum pump 11. A vacuum hole 13 is provided on the clamping frame 10 and the vacuum hose 12. A rubber pad 20 is provided on the clamping frame 10, and a filter screen 21 is provided on the vacuum hole 13.

[0030] In this embodiment, the workpiece is oscillated on the welding table 1, and the moving cylinder 9 is activated. The moving cylinder 9 drives the clamping frame 10 to move closer to the clamping frame 10 on the welding table 1, and flexibly clamps it through the rubber pad 20. Then, the vacuum pump 11 is activated, and the vacuum pump 11 draws air through the vacuum hose 12 and the vacuum hole 13. The vacuum hole 13 generates negative pressure, which adsorbs the surface of the workpiece and enhances the fixing effect. Then, the moving motor 16 is activated, and the moving motor 16 drives the moving screw 17 to rotate. The moving screw 17 drives the moving block 15 to move in the moving groove 14, thereby adjusting the position of the support frame 2, the support base 3 and the support platform 4. The steel component is pressed and fixed by the clamping device on the support platform 4, and another steel component is driven to be butt-welded with the clamped steel component.

[0031] Please see Figures 3-5 As one embodiment for adjusting the welded parts: the moving device includes a moving groove 14, a moving block 15 is provided on the moving groove 14, a support frame 2 is provided on the moving block 15, a moving motor 16 is provided on one side of the welding table 1, a moving screw 17 is provided on the motor shaft of the moving motor 16, the moving screw 17 is threadedly connected to the moving block 15, a second motor 18 is provided on the support base 3, a third gear 19 is provided on the second motor 18, a fourth gear 29 that cooperates with the third gear 19 is provided on the support platform 4, and the clamping device includes a clamping rod 22, a clamping block 23 is provided on the clamping rod 22, a clamping nut 24 is threadedly connected to the upper part of the clamping rod 22, a clamping groove 25 is provided on the clamping block 23, a clamping sleeve 26 is provided between the clamping rod 22 and the clamping groove 25, a clamping screw 27 is rotatably provided on the clamping groove 25, one end of the clamping screw 27 is rotatably connected to the clamping sleeve 26, and the other end is provided with a clamping knob 28.

[0032] More specifically, rotating the clamping knob 28 causes the clamping screw 27 to rotate, which in turn causes the clamping sleeve 26 to slide within the clamping groove 25. This adjusts the extension length of the clamping block 23 on the clamping rod 22, and the height of the clamping block 23 is clamped and limited by the clamping nut 24, thereby clamping and holding the steel component. The motor shaft of the first motor 5 drives the first gear 6 to rotate, which, in conjunction with the second gear 7, adjusts the tilt angle of the support base 3 by ±90°. The second motor 18 drives the third gear 19 to rotate, which in turn, through the fourth gear... 29 drives the support platform 4 to rotate 360° to meet the requirements of multiple postures such as flat welding, vertical welding, and overhead welding. The moving motor 16 is started, which drives the moving screw 17 to rotate. The moving screw 17 drives the moving block 15 to move in the moving groove 14, thereby driving the support platform 4 and the welding parts to adjust their positions and dock with the steel components fixed on the clamping device. Welding is performed between the steel components by a welding torch controlled manually or by a CNC machine tool. The welding torch structure, slag cleaning structure and exhaust gas collection device on the welding table 1 all adopt existing technologies. The structural diagram and specific principles will not be described in detail.

[0033] In summary, during the use or operation of the overall equipment: the workpiece is oscillating on the welding table 1, the moving cylinder 9 is activated, the moving cylinder 9 drives the clamping frame 10 to move closer to the clamping frame 10 on the welding table 1, and is flexibly clamped by the rubber pad 20. Then the vacuum pump 11 is activated, the vacuum pump 11 draws air through the vacuum hose 12 and the vacuum hole 13, the vacuum hole 13 generates negative pressure, adsorbs the surface of the workpiece, and enhances the fixing effect. Then the moving motor 16 is activated, the moving motor 16 drives the moving screw 17 to rotate, the moving screw 17 drives the moving block 15 to move in the moving groove 14, thereby adjusting the position of the support frame 2, support base 3 and support platform 4. The steel component is pressed and fixed by the clamping device on the support platform 4, and another steel component is driven to be butt-welded with the clamped steel component.

[0034] Rotating the clamping knob 28 causes the clamping screw 27 to rotate, which in turn causes the clamping sleeve 26 to slide within the clamping groove 25. This adjusts the extension length of the clamping block 23 on the clamping rod 22, and the height of the clamping block 23 is clamped and limited by the clamping nut 24, thereby clamping and holding the steel component. The motor shaft of the first motor 5 drives the first gear 6 to rotate, which, in conjunction with the second gear 7, adjusts the tilt angle of the support base 3 by ±90°. The second motor 18 drives the third gear 19 to rotate, which in turn drives the fourth gear 29 to rotate... The moving support platform 4 rotates 360° to meet the requirements of multiple postures such as flat welding, vertical welding, and overhead welding. The moving motor 16 is started, which drives the moving screw 17 to rotate.
