At one end of the support frame far from the double-headed motor, there is an L-shaped rod fixedly installed. On the upper side of the horizontal end surface of the L-shaped rod close to the transmission rod, there is a cross-shaped rod fixedly installed.

[0004] In view of the above related technologies, when the existing pipeline welding positioning device welds two adjacent pipelines, it can align the axes of the two pipelines with each other. However, pipelines with different thicknesses often require welds with different widths during welding. The existing positioning device is difficult to position adjacent pipelines in the axial direction of the pipelines. To sum up, the existing pipeline welding positioning device is difficult to control the distance between the axes of the pipelines while completing the coaxial positioning of the pipelines. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide a pipeline welding positioning device to solve the technical problem that the existing pipeline welding positioning device is difficult to control the distance between the axes of the pipelines while completing the coaxial positioning of the pipelines.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A pipeline welding positioning device, including a frame. Inside the frame, there are two parallel support beams installed along the length direction. On the support beams, there are support frames rotatably connected for carrying pipelines.

The diameter of the insertion rods is the width of the weld seam. By replacing the insertion rods and inserting them into the corresponding jacks, the effect of conveniently adjusting the weld seam of the pipes is achieved.

[0008] The present utility model is further configured such that the diameter of the jacks on the positioning frame gradually decreases from both sides towards the center.

[0019] By adopting the above technical solution, a good support foundation is provided for the pipes.

[0020] In summary, the present utility model mainly has the following beneficial effects:

[0021] 1. The utility model sets a positioning frame structure in the middle of the frame, and successively sets jacks with different apertures on the positioning frame. After inserting corresponding diameter plug rods into the jacks, the pipes to be welded are pushed towards each other until the plug rods are clamped.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0030] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0031] Embodiment 1

[0032] A pipe welding positioning device, as Figures 1-5As shown in the figure, it includes a frame 1. Inside the frame 1, two parallel support beams 2 are installed along the length direction. A support frame 3 for carrying pipes is rotatably connected to the support beams 2. A positioning frame 7 is fixedly connected to the middle of the frame 1. At the top of the positioning frame 7, a plurality of jacks 8 with different diameters are arranged in sequence towards the direction of the support beam 2. Plug rods 11 adapted to the hole diameters are inserted into the jacks 8. A chute 9 is arranged along the arrangement direction of the jacks 8 directly below the jacks 8 on the support beam 2. A slider 10 is slidably connected in the chute 9. The top of the slider 10 is provided with an inverted conical hole for the plug rod 11 to be inserted. Specifically, plug rods 11 with different diameters can accurately be inserted into the holes of the slider 10.

[0033] Please refer to Figures 1-2 , on both sides of the positioning frame 7, a plurality of support frames 3 are rotatably connected to the support beam 2. The plurality of support frames 3 are used to stably support the pipes to be welded. A driving component for driving the support frame 3 to rotate is arranged inside the support beam 2. Specifically, the driving component for driving the support frame 3 to rotate is a driving motor connected to the rotating shaft of the support frame 3. In order to accurately control the rotation angle of the support frame 3, the driving motor installed inside the support beam 2 is a servo motor. The driving component is used to drive the support frame 3 to rotate and adjust the angle, thereby realizing the height positioning of pipes with different diameters. The height of the positioning frame 7 is higher than the length of the support frame 3 to prevent the pipes from touching the positioning frame 7 after the support frame 3 supports the pipes.

[0034] Please refer to Figures 1-4 , the diameters of the jacks 8 on the positioning frame 7 gradually decrease from both sides to the center, for adapting to pipes to be welded with different diameters. Specifically, generally, the larger the diameter of the pipe, the thicker the wall thickness. Therefore, the jacks 8 with the largest diameters are the farthest apart. A plurality of support frames 3 on both sides of the positioning frame 7 are fixedly connected to each other through a connecting rod 12. The connecting rod 12 is used to connect the plurality of support frames 3 to each other, for enabling the support frames 3 on both sides of the positioning frame 7 to rotate synchronously, and providing a good support basis for the pipes.

[0035] Embodiment 2

[0036] A pipe welding positioning device, as Figures 1-5 shown, on the basis of Embodiment 1, the difference from Embodiment 1 is that an adjusting belt 4 in the shape of a conveyor belt is arranged on the top surface of the support frame 3. The rotating shafts of the adjusting belts 4 on both sides of the positioning frame 7 are connected to each other through a transmission rod 6. The transmission rod 6 is connected to an adjusting motor 5. Specifically, during the process of pipe welding, the adjusting belts 4 respectively located on the two support beams 2 work in opposite conveying directions, enabling the pipes on the support frame 3 to rotate around their own axes. When the welding head is fixed at the bottommost or topmost end of the weld seam, the circumferential welding work of the pipes can be easily completed through the self-rotation of the pipes. The adjusting belt 4 is used to control the rotation of the pipes on the support frame 3, for cooperating with the fixedly arranged laser welding head to perform the welding work on the pipes.

[0037] The working principle of the present utility model is as follows: Place the two pipes to be welded on the two support beams 2 of the frame 1 and keep them parallel to the support beams 2. After the support frames 3 are driven by the driving assembly, they rotate towards each other, making the support frames 3 in a V-shaped structure. At the same time, the adjusting belts 4 connected to the two support beams 2 rotate in the same direction to prevent the pipes from getting stuck between the support frames 3 when the support frames 3 rotate towards each other. After the support frames 3 rotate to the proper position, select an inserting rod 11 with a suitable diameter according to the wall thickness of the pipes and pass it through the corresponding-sized jack 8. Slide the slider 10 to the position directly below the corresponding jack 8, and insert the end of the inserting rod 11 into the slider 10. Then, push the two pipes towards each other until the two pipes are tightly pressed against the inserting rod 11. At this time, the diameter of the inserting rod 11 is the width of the weld between the pipes. Finally, remove the inserting rod 11 to perform the welding work of the pipes.

[0038] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and are not limitations thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not make creative contributions to the embodiments according to needs, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
