The front and rear sides of the base 1 are provided with an adjustment mechanism 2, one side of each clamping plate 14 is fixedly connected with a rubber pad 17, both sides of each movable rod 13 are fixedly connected with a slider 18, both sides of the interior of each U-shaped plate 10 are provided with a slide groove 19, and the sliders 18 are respectively slidably connected with the corresponding slide grooves 19, and the front and rear bottoms of the base 1 are provided with a second open groove 25, and the right side of the second open groove 25 is fixedly connected with a hydraulic rod 26, and the output end of the hydraulic rod 26 is fixedly connected with an L-shaped plate 27, and the adjacent sides of the two L-shaped plates 27 are respectively fixedly connected with the front and rear sides of the corresponding first arc plate 8;

[0040] Specifically, when the servo motor 11 is started, it can drive the screw 12 to rotate. This process may seem like a simple physical movement, but in fact, it triggers a series of chain reactions, thereby realizing an efficient production process. While the screw 12 rotates, the second pulley 15 on its outer side will also rotate accordingly. This design cleverly transfers mechanical energy to the corresponding first pulley 7 on the rotating shaft 6. Through the connection of the transmission belt 16, the first pulley 7 will also rotate. This rotation process not only drives the second pulley 15 on the rear screw 12 to rotate, but also causes the rear screw 12 to rotate accordingly. At this time, the movable rods 13 on the multiple screws 12 play a key role. They drive the surrounding clamps 14 to move toward the middle to limit and fix the pipeline. This design allows the device to limit and fix pipelines of different sizes, greatly improving the adaptability of the equipment. No matter what kind of pipeline the user needs to fix, it only needs to adjust the position of the movable rod 13 to meet their needs.

[0041] Reference Figure 1 , Figure 2 and Figure 4 The adjusting mechanism 2 includes a support rod 201, and the two support rods 201 are fixedly connected to the front and rear sides of the base 1 respectively. The outer side of the support rod 201 is slidably connected with a sleeve 202, and the top of the sleeve 202 is fixedly connected with the sleeve 202. The top of the sleeve 202 is provided with a groove 203, and the inside of the groove 203 is rotatably connected with a ball 204. The right side of the sleeve 202 is threadedly connected with a first bolt 205, and one end of the first bolt 205 passes through the sleeve 202 and the ball 204 in sequence. The top of the ball 204 is fixedly connected with a connecting rod 206, and the top of the front connecting rod 206 is fixedly connected with a milling device 207, and the top of the rear connecting rod 206 is fixedly connected with a heating plate 208;

[0042] Specifically, after the pipeline is fixed in position, the sliding sleeve 202 on the front support rod 201 is first moved to the middle position, and then the first bolt 205 is loosened, so that the position limit on the ball 204 can be released. At this time, rotate the front sphere 204 to make the milling device 207 parallel to the pipe, then tighten the second bolt 21, and drive the right pipe to move to the middle through the hydraulic rod 26 until it contacts the milling cutter. This step is to ensure that the milling device 207 can accurately mill the pipe port, and then start the milling device 207 to mill the two pipe ports, so as to ensure the flatness of the two pipe ports and lay a solid foundation for subsequent heating and welding work. After the milling work is completed, repeat the previous operation and move the rear heating plate 208 to the middle position. Next, heat and weld the two pipe ports. After the welding work is completed, remove the device from the pipe to complete the entire pipe docking process. During the entire operation, there is no need to separately transport, disassemble and assemble the milling device 207 and the heating plate 208 before welding, which makes the pipe docking process faster and simpler, and greatly improves work efficiency.

[0043] Reference Figure 1 and Figure 3 The front sides of the plurality of first curved plates 8 and the second curved plates 9 are fixedly connected with a connecting plate 20, the top of the connecting plate 20 is threadedly connected with a second bolt 21, the bottom end of the second bolt 21 passes through the connecting plate 20, and a movable shaft 22 is provided on the rear side of the first curved plate 8, and the two first curved plates 8 are rotatably connected with the rear side of the corresponding second curved plate 9 through the movable shaft 22;

[0044] Specifically, the connection between the first arc plate 8 and the second arc plate 9 can be released by loosening the second bolt 21, so that the pipes to be processed can be conveniently placed in the corresponding fixtures.

[0045] Reference Figure 1A switch 23 is fixedly connected to the right side of the base 1, and the switch 23 is electrically connected to the milling device 207, the heating plate 208, the servo motor 11 and the hydraulic rod 26 respectively. A protective cover 24 is arranged on the outer side of the switch 23, and the left side of the protective cover 24 is rotatably connected to the right side of the base 1;

[0046] Specifically, the operations of the milling device 207, the heating plate 208, the servo motor 11 and the hydraulic rod 26 can be controlled by the switch 23, and the protective cover 24 can protect the switch 23 from being damaged by external factors.

[0047] Working principle: When using the device, first loosen the second bolts 21 on both sides and then open the second curved plate 9. At this time, put the pipes to be welded on the two first curved plates 8 respectively, and then lock the second curved plate 9 through the second bolts 21. At this time, start the servo motor 11 to drive the screw rod 12 to rotate. While the front screw rod 12 rotates, the second pulley 15 on its outer side will rotate accordingly, and the first pulley 7 corresponding to it on the rotating shaft 6 will also rotate through the transmission belt 16, so as to drive the second pulley 15 on the rear screw rod 12 to rotate, and the rear screw rod 12 will rotate accordingly. At this time, the movable rods 13 on the multiple screw rods 12 will drive the surrounding clamping plates 14 to move to the middle to limit and fix the pipe. Pipes of different sizes can be limited and fixed, so as to meet the needs of users. After the pipe is limited and fixed, first move the front support rod 2 01 is moved to the middle position, and then the first bolt 205 is loosened to release the limit on the sphere 204. At this time, the front sphere 204 is rotated to turn the milling device 207 to be parallel to the pipeline, and then the second bolt 21 is screwed on. The hydraulic rod 26 can drive the right pipeline to move to the middle until it contacts the milling cutter, and then the milling device 207 is started to perform milling work on the two pipeline ports to ensure the flatness of the two pipeline ports. After the milling work is completed, the above operation is repeated to move the rear heating plate 208 to the middle position, and the ports of the two pipelines are heated and welded. After the welding work is completed, the device can be removed from the pipeline. There is no need to carry and disassemble the milling device 207 and the heating plate 208 before welding work, so that the pipeline can be quickly operated and docked, thereby improving the practicality of the device.
