It is often used in the production of important steel structures such as pressure vessels, pipe section manufacturing, box beams and columns. It is also widely used in the manufacture of large engineering structures such as shipbuilding, bridges, and lifting machinery.

The third motor 483 is connected to an upper side of a side surface of the first movable plate 41 through a support frame 484. Start the third motor 483 to drive the second gear 482 to mesh with the second tooth 481 counterclockwise, so that the transmission ring plate 48 drives the rotating ring plate 42, the pressing ring plate 43, the pressing block 461, and the first pipe 7 to rotate counterclockwise, wherein the first ring plate 421 on the rotating ring plate 42 rotates counterclockwise in the rotating groove on the rotating track plate 411, so that the first pipe 7 can be fixed inside the rotating ring plate 42 and rotate counterclockwise.

It is conducive to realizing the automatic welding work, without manual participation in the welding work, and effectively reducing the workload, and also preventing the welding parts 68 from shaking during welding, improving the welding quality, uniformity, and aesthetics.

[0048] In this embodiment, a side surface of the movable plate 41 is fixedly connected to a limiting rod 49, one end of which passes through a limiting hole 52 on the second movable plate 51, and the first clamping mechanism 4 and the second clamping mechanism 5 have the same structure, which is conducive to ensuring the stability of the movement of the first pipe 7 and the second pipe 71.

[0049] In this embodiment, the positioning mechanism 6 includes a fixed frame 61 fixedly connected to one side of the upper end surface of the workbench 1, and the fixed long plate on the fixed frame 61 is slidably fitted in a moving port 621 opened at the lower part of the moving shell 62.

The first guide surface 6921 is subjected to force to drive the telescopic plate 66, the guide plate 67, the telescopic rod 65, the hydraulic cylinder 64, the track plate 63, and the moving shell 62 to move to one side.

At the same time, the second guide surface 6922 on the positioning plate 692 moves toward the port surface of the second pipeline 71 until the port of the second pipeline 71 presses against the second guide surface 6922. Then, the moving shell 62 stops moving.

In addition, it can effectively prevent the upper part of the relative ports of the first pipe 7 and the second pipe 71 from being scratched, thereby enhancing protection.

[0050] In this embodiment, the first guide surface 6921 and the second guide surface 6922 are provided on both sides of the lower part of the positioning plate 692, and a rounded corner 6923 is formed in the middle of the lower end of the positioning plate 49. The first guide surface 6921 and the second guide surface 6922 are in contact with the end surfaces of the first pipe 7 and the second pipe 71 opposite to each other, which is beneficial to the automatic positioning of the docking point of the relative ports of the first pipe 7 and the second pipe 72 through the guidance and transmission of the positioning plate 692.

At this time, the positioning plate 692 is moved upward by the two-way pressing of the first pipe 7 and the second pipe 71 until the first pipe 7 and the second pipe 71 are connected to the opposite ports. At this time, the welding piece is located at the connection between the first pipe 7 and the second pipe 71, which can improve functionality and accuracy;

[0057] S6, welding: starting the welding piece to weld the first pipe 7 and the second pipe 71 that have been connected;

[0058] S7, rotation: start the third motor 483, so that the transmission ring plate 48 drives the first ring plate 421 to rotate counterclockwise on the rotating track plate 411, so that the first pipe 7 can rotate counterclockwise, and the second pipe 71 opposite to it can rotate counterclockwise through the second clamping mechanism 5 at the same time, thereby realizing the synchronous counterclockwise rotation of the first pipe 7 and the second pipe 71, and then utilizing the welding of the welding parts that have been started long ago, thereby realizing the automatic welding work, and realizing the automatic welding work, without the need for manual participation in the welding work, and effectively reducing the workload.

[0059] The specific working principle of the present invention includes the following process:

[0060] First, place the first pipe 7 and the second pipe 71, wherein the first pipe 7 is placed inside the rotating ring plate 42, the rotating track plate 411, the clamping ring plate 43, and the transmission ring plate 48, and the second pipe 71 works the same as the first pipe 7. After placement, start the second motor 442 to drive the first gear 441 to mesh with the first tooth 44 clockwise, and the clamping ring plate 43 is forced to rotate inside the clamping ring groove 422 through the second annular plate 431. At the same time, a plurality of pressing blocks 432 are pressed against a plurality of T-shaped plates 46 and the pressing blocks 461, and the pressing blocks 432 are forced to slide downward at The plurality of pressing blocks 461 are gradually pressed downward against the outer side of the first pipe 7 as the clamping ring plate 43 continues to rotate. After the plurality of pressing blocks 461 are completely pressed against the outer side of the first pipe 7, the first pipe 7 is located in the middle of the rotating ring plate 42. At this time, the second motor 442 is stopped, thereby being fixed to the first pipe 7. The relative second pipe 71 is fixed by the second clamping mechanism 5 in accordance with the operation thereof, wherein the first pipe 7 and the second pipe 71 are on the same central axis.

[0061] After fixing the first pipe 7 and the second pipe 71, the motor 21 is started to drive the rotating circular plate 22 to rotate counterclockwise. The rotating circular plate 22 is subjected to force and drives the two transmission plates 23 at the same time through the two transmission rods. The transmission plate 23 is subjected to force to drive the sliding block 24 to move outward. At the same time, the sliding block 24 slides in the transmission groove 251 through the sliding plate 241. The guide rod 344 is subjected to force to resist in the long notch 271, so that the rotating plate 27 is subjected to force to rotate counterclockwise on the outside of the fixed rod. The push rod 272 is subjected to force transmission to the push plate 291 and the pressure rod 292, and the pressure plate 294 moves to one side. At the same time, the pressure plate 294 drives the first clamping mechanism 4 and the first pipe 7 to gradually move toward the second pipe 71. The second pipe 71 opposite to it is driven by the second docking mechanism 3, so that the second pipe 71 gradually moves toward the first pipe 7. Among them, the limit rod 49 slides to one side in the limit hole 52.

[0062] Before the first pipeline 7 and the second pipeline 71 move relative to each other, the positions of the positioning plate 692 and the welding piece 68 are adjusted according to the size of the pipeline, and the hydraulic cylinder 64 can be started to drive the telescopic rod 65 to move to one side. The telescopic plate 66 is forced to slide to one side in the guide groove on the track plate 63 through the guide plate 67, so that the welding piece 68 and the positioning plate 692 can be moved in the direction of the first pipeline 7 and the first pipeline 71 until the welding piece 68 can be welded to the welding point of the first pipeline 7 and the second pipeline 71. The size of the pipeline can change the position of the positioning plate 692. For example, if the pipeline has a larger diameter, the positioning plate 692 is located on one side of the welding point of the two pipelines, and the positioning plate 692 is not located in the middle of the welding point of the two pipelines (such as Fig. 9 shown).

[0063] During the relative movement of the first pipe 7 and the second pipe 71, due to the different lengths of the pipes placed, the longer pipe is first pressed against the positioning plate 692. For example, when the length of the first pipe 7 is longer, the first pipe 7 is first pressed against the first guide surface 6921 during the movement. The first guide surface 6921 is forced to drive the telescopic plate 66, the guide plate 67, the telescopic rod 65, the hydraulic cylinder 64, the track plate 63, and the moving shell 62 to move to one side, and the moving port 621 slides to one side on the outer side of the fixed long plate on the fixed frame 61. At the same time, the second guide surface 6922 moves toward the second pipe 7. 1 until the port of the second pipe 71 is pressed against the second guide surface 6922, and the moving shell 62 stops moving. At this time, by utilizing the two-way pressing of the first pipe 7 and the second pipe 71 and the guidance of the first guide surface 6921 and the second guide surface 6922, the positioning plate 692 is driven upward by the positioning rod 692 and stretched upward by the second spring body 691. At the same time, the positioning plate 692 moves upward in the through port 661 until the first pipe 7 and the second pipe 71 are connected to each other with respect to the ports, and the welding parts are automatically adjusted in position by the positioning plate 692.

[0064] Under the pressure of the first pipe 7 and the second pipe 71, the position of the welding part has been automatically adjusted. At this time, the welding part is started to weld the docking point of the relative ports of the first pipe 7 and the second pipe 71. At the same time, the third motor 483 is started to drive the second gear 482 to engage with the second tooth 481 counterclockwise, so that the transmission ring plate 48 drives the rotating ring plate 42, the clamping ring plate 43, the pressing block 461, and the first pipe 7 to rotate counterclockwise in a counterclockwise manner, wherein the first annular plate 421 rotates counterclockwise in the rotating groove on the rotating track plate 411, so that the first pipe 7 can be fixed inside the rotating ring plate 42 and rotate counterclockwise. When the first pipe 7 rotates, the second pipe 71 relative to it rotates counterclockwise through the second clamping mechanism 5, thereby realizing the synchronous counterclockwise rotation of the first pipe 7 and the second pipe 71, and then utilizing the welding of the welding part to realize the automatic welding work.
