[0040] Working principle:

[0041] When in use, the base 1 is moved to a designated location, and then the column is placed horizontally and passed through the supporting device 3. Then, the bottom of the column is fixed by the position adjustment device 2, and then the position of the supporting device 3 is adjusted, and the column body is supported by the supporting device 3. Then, the position where the connecting plate is installed on the surface of the column can be welded by the welding device 4;

[0042] When fixing the column, the hydraulic telescopic rod 223 in the clamping assembly 22 is extended, and the disc 224 moves toward the outside of the housing 221 together with the output end of the hydraulic telescopic rod 223. At this time, the movable rod 225 can drive the slider 226 to slide in the rectangular hole opened on the surface of the limit plate 222 as the disc 224 moves. At this time, the four stepped positioning blocks 227 can approach each other as the slider 226 moves, and clamp the bottom of the column. The outer edge of the stepped positioning block 227 is stepped, which can clamp the edge of the bottom of the column when fixing, so as to prevent the column from shaking laterally after being fixed, thereby fixing the bottom of the column;

Then, when the position adjustment device 2 drives the column to rotate, the rotating ring 32 can rotate relative to the fixing frame 31, thereby assisting in supporting the column and preventing the surface load of the position adjustment device 2 from being too large.

[0045] During welding, the servo motor 41 drives the screw rod 42 to rotate along the inner side of the bearing seat 43, so that the adjustment block 44 moves along the surface of the screw rod 42 as the screw rod 42 rotates. At this time, the nitrogen charging component 45 installed on the top of the adjustment block 44 can drive the welding gun 46 to move together with the adjustment block 44, thereby expanding the movement range of the welding gun 46 to adapt to columns of different heights. In this process, the guide wheel 452 in the nitrogen charging component 45 rolls in the guide groove provided at the bottom of the base 1, which can reduce the friction resistance of the nitrogen charging component 45 when it moves;

[0046] During the welding process, the robot arm 453 can adjust the position of the welding gun 46, and the shielding shell 454 can shield the light generated during welding. At the same time, the pressure regulating valve 456 is opened to allow the nitrogen in the nitrogen tank 455 installed on the top of the mobile frame 451 to enter the shielding shell 454 through the connecting hose 458, and discharge the oxygen in the shielding shell 454 to prevent the welding point from contacting with the oxygen in the air, thereby achieving the purpose of preventing the weld from oxidation;

[0047] When nitrogen passes through the connecting hose 458, part of the nitrogen enters the main shell 572 in the exhaust component 457. At this time, the fan 574 is driven by the flowing nitrogen to rotate. At this time, the rotating shaft 573 can drive the fan blades 576 to rotate together with the fan 574. When rotating, the fan blades 576 can discharge the air in the side shell 571 through the ventilation plate 577, and at the same time, the smoke generated during welding in the shielding shell 454 and a small amount of nitrogen are sucked in through the exhaust hose 459. At this time, the inhaled gas can be discharged after being filtered by the smoke adsorption plate 575, thereby reducing the pollution of the air by the smoke generated during welding.
