[0025] When welding the iron pipe and the flange, first place the flange on the placing truncated table 2, and make the outer circumference of the flange close to the positioning plate 4, so that the center of the flange coincides with the center of the placing truncated table 2. The positioning plate 4 can be replaced according to flanges of different sizes. The lower end of the iron pipe passes through the iron pipe fixing assembly 6, and the iron pipe fixing assembly 6 maintains the vertical state of the iron pipe. Then, the rotating drive assembly 1 drives the flange to rotate, and the flange welding assembly 8 welds the flange and the lower end of the iron pipe. The first adjustment bracket 5 and the second adjustment bracket 7 are respectively used to adjust the positions of the iron pipe fixing assembly 6 and the flange welding assembly 8 before welding. The advantage of this design is that when placing the workpiece, it is easy to align the center of the iron pipe, the flange and the placing truncated table 2, thereby improving the welding accuracy. Through the iron pipe fixing assembly 6, the verticality of the iron pipe can be maintained to avoid tilting of the iron pipe, further improving the welding accuracy. Through the rotating drive assembly 1, the workpiece rotates automatically, saving manpower and improving efficiency.

[0026] An opening 31 is provided on one side of the annular rib 3 , so that the flange can be placed into the placing truncated table 2 through the opening 31 to avoid damaging the annular rib 3 .

[0027] The first adjustment bracket 5 includes a mounting pole 51, a height adjustment block 52, a first angle adjustment block 53, a second angle adjustment block 54 and a length adjustment rod 55. The mounting pole 51 is fixedly arranged on one side of the truncated table 2. The height adjustment block 52 is fixed on the mounting pole 51 and is adjustable in height. The first angle adjustment block 53 is fixed on the height adjustment block 52 and is adjustable in angle. Both ends of the length adjustment rod 55 are respectively fixed on the first angle adjustment block 53 and the second angle adjustment block 54. The second angle adjustment block 54 is adjustable in length and angle on the length adjustment rod 55. The iron pipe fixing assembly 6 is fixed on the second angle adjustment block 54.

[0028] The position of the iron pipe fixing assembly 6 can be flexibly adjusted by the height adjustment block 52 , the first angle adjustment block 53 and the second angle adjustment block 54 .

[0029] The iron pipe fixing assembly 6 includes a connecting plate 61, an installation iron ring 62 and an elastic clamping component 63. The connecting plate 61 is fixed on the second angle adjustment block 54. The installation iron ring 62 is fixed on the connecting plate 61 and corresponds to the top of the flange welding assembly 8. The center of the installation iron ring 62 coincides with the center of the placement of the truncated table 2. The elastic clamping component 63 is fixed on the installation iron ring 62 and the inner end is an elastic telescopic end. Multiple groups of elastic clamping components 63 are evenly arranged on the installation iron ring 62.

[0030] Insert the lower end of the iron pipe into the inner side of the mounting iron ring 62, and stretch the elastic end of the elastic clamping component 63 outward. After the lower end of the iron pipe is placed in place, the elastic clamping component 63 presses the outer periphery of the iron pipe to maintain the verticality of the iron pipe during welding.

[0031] The elastic clamping component 63 includes a pull rod 631, an inner stop ring 632, an outer stop ring 633, a spring 634, a roller 635 and a pull ring 636.

The inner stop ring 632 and the outer stop ring 633 correspond to the inner and outer sides of the mounting iron ring 62 respectively. The spring 634 is sleeved on the pull rod 631 and its two ends are respectively in contact with the mounting iron ring 62 and the inner stop ring 632. The roller 635 is rotatably mounted on the inner end of the pull rod 631, and the pull ring 636 is fixed on the outer end of the pull rod 631.

[0032] The pull rod 631 can rotate on the installation iron ring 62. When the iron pipe is placed in the installation iron ring 62, the lower end of the iron pipe contacts the roller 635. Under the action of friction, the roller 635 gradually turns to the longitudinal direction, that is, the rotation direction of the roller 635 is consistent with the insertion direction of the iron pipe, and the spring 634 is compressed. The pull ring 636 can also be manually pulled to make a group of rollers 635 run outward in advance to provide space for the placement of the iron pipe. When the rotating drive component 1 drives the flange to rotate, the iron pipe also rotates, and the roller 635 gradually turns to the transverse direction, that is, the rotation direction of the roller 635 is consistent with the rotation direction of the iron pipe. The roller 635 presses the iron pipe under the action of the spring 634 to maintain the verticality of the iron pipe.

[0033] The height adjustment block 52, the first angle adjustment block 53, the second angle adjustment block 54, the length adjustment rod 55 and the iron pipe fixing assembly 6 are each provided with two groups on the mounting pole 51.
