[0016] Please see Figures 1-3In this embodiment of the present invention, an automatic welding device for pipe connection includes two arc-shaped outer shells 1. A hinge 2 is installed at the lower end connection of the two arc-shaped outer shells 1. Two sets of through grooves 4 are symmetrically opened on each of the two arc-shaped outer shells 1. Rollers 5 are rotatably installed inside each of the four sets of through grooves 4. A welding window 6 is opened at the middle of one of the arc-shaped outer shells 1, and a welding cavity 9 is installed inside the welding window 6. Sliding grooves 11 are opened at both ends of the arc-shaped outer shells 1. Movable seats 14 are slidably installed inside the sliding grooves 11. A connecting plate 12 is installed at the outer end of the movable seat 14. A suction cup 13 that attracts the pipe wall is movably installed on the connecting plate 12. In use, the two arc-shaped outer shells 1 are wrapped around the outer wall of the pipe. The pipe joint is aligned, improving welding accuracy. Rotating the adjusting bolt 10 moves the suction cup 13, causing it to adhere to the outer wall of the pipe, thus fixing the pipe and improving welding stability. Moving the arc-shaped outer shell 1, under the action of the roller 5, causes the equipment to rotate on the outer wall of the pipe, making the welding window 6 move in a circle on the pipe surface, further exposing the pipe joint. The welding head is then inserted into the welding cavity 9, facilitating welding and significantly improving welding efficiency and accuracy. In addition, the sliding connection between the slide groove 11 and the movable seat 14 prevents the arc-shaped outer shell 1 from affecting the suction cup 13 when rotating, improving the stability of the equipment after installation.

[0017] exist Figure 1 In the middle, crossbars 7 are symmetrically installed inside the welding window 6, and a base plate 8 fixedly connected to the welding cavity 9 is installed between the two crossbars 7, which is conducive to the installation of the welding head.

[0018] exist Figure 1 In the middle, the welding cavity 9 is provided with anti-slip ribs to facilitate the installation of the welding head, and one end of the welding cavity 9 passes through the base plate 8. The base plate 8 is an arc-shaped component that is convenient to rotate on the outer wall of the pipe.

[0019] exist Figure 1 and Figure 2 In the middle, the top of the arc-shaped outer shell 1 is equipped with connecting seats 3 at both ends. The two opposite connecting seats 3 are connected by snap-fit, and the installation of the device is achieved by the snap-fit ​​of the connecting seats 3.

[0020] exist Figure 3 In the middle of the connecting plate 12, an adjusting bolt 10 is installed, which is rotatably connected to the suction cup 13. A spring 15 is also installed between the connecting plate 12 and the suction cup 13. Rotating the adjusting bolt 10 will drive the suction cup 13 to move. Under the traction of the spring 15, the suction cup 13 moves towards the center of the pipe, so that the suction cup 13 is attracted to the outer wall of the pipe.

[0021] exist Figure 1In the middle, the slide 11 is a semi-circular structure component, and the upper end of the slide 11 is open to facilitate the movement of the movable seat 14.

[0022] The working principle of this utility model is as follows: This utility model has a simple structure and novel design. In use, two arc-shaped outer shells 1 are wrapped around the outer wall of the pipe. The installation of the equipment is achieved by the interlocking of the connecting seats 3, thereby aligning the pipe interface and improving the accuracy of welding. Rotating the adjusting bolt 10 drives the suction cup 13 to move. Under the traction of the spring 15, the suction cup 13 moves towards the center of the pipe, thereby attracting the suction cup 13 to the outer wall of the pipe and fixing the pipe, thus improving the stability of pipe welding. Moving the arc-shaped outer shell 1 causes the equipment to rotate on the outer wall of the pipe under the action of the roller 5, thereby causing the welding window 6 to make a circular motion on the surface of the pipe, further exposing the pipe interface. The welding head is then inserted into the welding cavity 9, which facilitates welding and greatly improves welding efficiency and accuracy. In addition, the sliding connection between the sliding groove 11 and the movable seat 14 can prevent the rotation of the arc-shaped outer shell 1 from affecting the suction cup 13, thus improving the stability of the equipment after installation.
