Description

Technical Field

[0001] The utility model relates to the technical field of water pipe welding, in particular to a welding tool for a branch water pipe. Background Art

[0002] The branch water pipe includes a main pipe and branch pipes. A plurality of branch pipes are arranged on one main pipe to divide the medium in the main pipe and flow it in different directions or to different devices along the branch pipes, and it is widely used in heating systems, industrial or air-conditioning water systems.

[0003] The main pipe and the branch pipes of the branch water pipe are connected by welding, and one end of the branch pipe is welded to the surface of the main pipe. Since the surface of the main pipe is a smooth arc surface, it is difficult to position the branch pipe and the main pipe during welding. During the welding process, the positions of the branch pipe and the main pipe are likely to shift, affecting the welding efficiency. At the same time, one main pipe often needs to weld a plurality of branch pipes, and the orientations of the branch pipes are different, so the welding cycle of the branch water pipe is relatively long.

[0004] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Utility Model

[0024] The specific structures of the support plate 2, the second arc groove 31 and the pressing block 4 are described as follows:

[0025] Figure 3 Fig. shows a schematic three-dimensional structure diagram of the water distribution pipe welding tooling in the bottom view direction in Embodiment 1 of the present utility model. Please refer to Figure 3 An extension part 22 is arranged on the lower surface of the support plate 2 facing downwards, and the support plate 2 is inserted into the bottom plate 1 through the extension part 22. The support plate 2 and the bottom plate 1 are connected by insertion, and the support plate 2 can be conveniently replaced to support the main pipes 5 of different models. The support plate 2 fits the side plate 3, increasing the stability of the support plate 2 and the side plate 3. Along the axis direction of the first arc groove 21, at least two support plates 2 are arranged, and multiple support plates 2 can better support the main pipe 5 and reduce the deformation of the main pipe 5 during welding.

[0026] Please refer to Figure 1 , and it further includes a pressing block 4. A third arc groove 41 with an opening facing downwards is formed on the pressing block 4, and the third arc groove 41 is arranged in the same direction as the first arc groove 21. The pressing block 4 cooperates with the support plate 2 to fix the main pipe 5, enhancing the stability during the welding of the main pipe 5. Elastic pads are arranged in the first arc groove 21 and the second arc groove 31. Through the elastic pads, the first arc groove 21 and the second arc groove 31 can better fit the main pipe 5 and the branch pipe 6, enhancing the stability of the main pipe 5 and the branch pipe 6 during welding.

[0027] The specific working process of the present utility model is as follows:

[0028] During welding, first place the branch pipe 6 in the positioning hole 11. Then place the main pipe 5 on the support plate 2, with the first arc groove 21 fitting the arc surface of the main pipe 5. Then rotate the main pipe 5 around the axis of the first arc groove 21 to align the welding position of the main pipe 5 with the branch pipe 6. Move the pressing block 4 to make the third arc groove 41 on the pressing block 4 fit the main pipe 5. If there is also a branch pipe 6 to be welded on the side of the main pipe 5 facing the side plate 3 at this time, place the branch pipe 6 in the second arc groove 31, and this branch pipe 6 abuts against the main pipe 5. Then the main pipe 5 and the branch pipe 6 can be welded.

Please refer to Figure 4 , based on Embodiment One, Embodiment Two discloses a bottom plate 1, and its positioning hole 11 includes a plurality of circular holes with different diameters, and the plurality of circular holes are coaxially arranged. As the diameter of the circular hole decreases, the depth of the circular hole increases. The circular holes with different diameters can be adapted to branch pipes 6 with different diameters. The plurality of circular holes with different diameters can cooperate with branch pipes 6 of various diameters, and the steps formed between the circular holes with different diameters can abut against the end face of the branch pipe 6, ensuring the stability of the fixation of the branch pipe 6. It increases the practicality of the tooling.

The diameter of the tapered hole changes continuously. If the diameter of the branch pipe 6 is between the maximum diameter and the minimum diameter of the tapered hole, then this branch pipe 6 can be fixed by this tapered hole, and one positioning hole 11 can be adapted to branch pipes 6 of various diameters.

[0033] Embodiment Four

[0034] Figure 6The schematic diagram of the cooperation structure between the support plate and the pressing block in the fourth embodiment of the present utility model is shown. Please refer to Figure 6 , based on the first, second, and third embodiments, the fourth embodiment discloses a connection structure between a pressing block 4 and a support plate 2, wherein one end of the pressing block 4 is rotatably connected to the support plate 2, and the rotation direction of the pressing block 4 is perpendicular to the axis direction of the first arc groove 21.
