In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

Embodiment 1:

1-3, the adjustment assembly includes two symmetrically arranged moving plates 5, and also includes: a rotating disk 6, which is rotatably connected to the adjacent side of the two moving plates 5 through a rotating shaft; a positioning column 7, which is fixedly connected to the center of the side of the rotating disk 6 away from the moving plate 5; an adjustment motor 10, which is fixedly connected to one of the moving plates 5; a transmission gear 1001, which is fixedly connected to the driving end of the adjustment motor 10; a transmission ring gear 601, which is fixedly connected to the rotating disk 6 on the side close to the adjustment motor 10, and the transmission ring gear 601 is meshed with the transmission gear 1001.

When the flange and the pipeline are welded and fixed, the staff can respectively set the two flanges on the two positioning posts 7, and then place the pipeline to be welded with the flanges horizontally between the two flanges, and then control the two moving plates 5 to approach each other, and the moving plates 5 will drive the two rotating disks 6 to approach each other. At this time, the flange will approach the pipeline under the push of the rotating disk 6. As the flange continues to approach the pipeline, the positioning post 7 will be inserted into the pipeline to support the pipeline, and then continue to control the flange to move until the flange and the end of the pipeline are tightly attached, and then the two sides of the flange will be tightly against the pipeline and the rotating disk 6 respectively, and then the welding staff can hold the welding gun and the welding rod to perform welding operation on the connection between the flange and the pipeline. When the welding staff completes the welding of the connection between the flange and one side of the pipeline, the adjusting motor 10 can be started at this time, and the adjusting motor 10 will drive the transmission gear 1001 to rotate, and the transmission gear 1001 will drive the rotating disk 6 on one side to rotate through the transmission gear ring 601. The moving plate 6 is closely attached to the two flanges respectively, so when one of the rotating plates 6 rotates, the flange and the pipeline can be driven to rotate. When the flange and the pipeline rotate to the other side, the welding staff will weld the connection between the flange and the other side of the pipeline, so as to complete the welding work of the flange and the pipeline, and then control the two moving plates 5 to move away from each other, so that the positioning column 7 is separated from the pipeline and the flange, and the welded flange and the pipeline as a whole can be removed from the adjustment component for the next flange and pipeline welding operation. Through the coordinated use of the moving plate 5, the rotating plate 6, the positioning column 7, the adjustment motor 10, the transmission gear 1001 and the transmission gear ring 601, when the flange and the pipeline are fixed, the flange and the pipeline can always be on the same central axis. When the flange and the pipeline are welded, the flange and the pipeline can be automatically rotated and adjusted, without the need for the welding worker to change the welding, which can not only improve the welding quality during the flange welding, but also reduce the workload of the welding personnel, and effectively improve the welding efficiency of the flange welding.

The positioning air bag 8 is connected to the air delivery cavity 701 through an air delivery pipe 702. When the positioning column 7 passes through the flange and extends into the pipeline, the inner body can be transported to the air delivery cavity 701 through the air pipe, and then the gas in the air delivery cavity 701 will be transported into the positioning column through the air delivery pipe 702. Inside the airbag 8, as the gas in the positioning airbag 8 continues to increase, the air pressure continues to increase, and the positioning airbag 8 will continue to expand. When the positioning airbag 8 is in contact with the flange and the inner wall of the pipe, the center of the flange and the pipe will be adjusted under the action of the positioning airbag 8, so that the center of the flange and the pipe are on the same central axis, so that the flange and the pipe can be adjusted more accurately, effectively improving the quality of the welding between the flange and the pipe. At the same time, through the setting of the positioning airbag 8, the adjustment component can also be adjusted to flanges and pipes of different diameters, effectively improving the applicability of the adjustment component.

When the adjustment component is applied to the flange welding equipment and the flange needs to be welded to the pipeline, the flange can be firstly put on the positioning column 7, and then the staff can set the pipeline horizontally between the two positioning columns 7, and then the driving motor 4 can be started, and the driving motor 4 will drive the two movable plates 5 to approach each other through the bidirectional screw rod 3. When the two positioning After the columns 7 are respectively inserted into the ports on both sides of the pipeline, the staff can release the pipeline, and then continue to control the two movable plates 5 to approach each other until the two sides of the flange are tightly attached to the pipeline and the rotating disk 6 respectively. Then the staff can hold the welding gun to weld the connection between the flange and the pipeline. When the welding of the connection position of the flange and the pipeline is completed, the adjusting motor 10 can be started at this time. The adjusting motor 10 can drive the transmission gear 1001 to rotate, and the transmission gear 1001 will drive the rotating disk 6 to rotate through the transmission gear ring 601, so that the rotation position of the flange and the pipeline can be adjusted, and then the staff can weld the connection between the flange and other positions of the pipeline. The connection between the flange and the pipeline can be welded without the staff moving, which can not only improve the welding efficiency, but also reduce the workload of the staff, providing convenience for the staff.

Two groups of hydraulic telescopic cylinders 103 are symmetrically fixedly connected at the middle position of the base 1, and an arc-shaped lifting plate 104 is fixedly connected to the telescopic ends of the two groups of hydraulic telescopic cylinders 103. When the staff respectively sleeve the two flanges on the two positioning columns 7, the staff can place the pipes that need to be welded with flanges on the arc-shaped lifting plate 104, and then start the hydraulic telescopic cylinders 103.
