[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0029] like Figure 1 and Figure 2 As shown, a water supply pipe welding device includes a belt drive assembly 7 (the belt drive assembly 7 is prior art, and its principle and components are not described, but its specific structure is shown in the figure), which includes a placement platform 1, a V-groove 2, a first rotating shaft 4, a first rotating roller 5, and a second rotating shaft 6.

[0030] Two placement platforms 1 are symmetrically arranged on the ground, and each placement platform 1 has V-shaped grooves 2 of the same size that are directly opposite each other.

[0031] The first mounting groove 3 is symmetrically opened on the V-shaped groove 2;

[0032] The first rotating shaft 4 is rotatably connected in the first mounting groove 3 and one end of the first rotating shaft 4 passes through the first mounting groove 3 and the placement platform 1 in sequence, extending to the outside of the placement platform 1.

[0033] The first rotating roller 5 is located outside a local area of ​​the first rotating shaft 4 and its top end is higher than the first mounting groove 3. The bottom end of the first rotating roller 5 is spaced apart from the bottom of the first mounting groove 3.

[0034] The second rotating shaft 6 is rotatably connected to the placement platform 1 and is located directly below the first rotating shaft 4;

[0035] The first rotating shaft 4 and the second rotating shaft 6 are connected by a belt drive assembly 7.

[0036] In a further refinement of the embodiment of this utility model, a six-degree-of-freedom robotic arm is provided on one side of the ground between the two placement platforms 1, and the six-degree-of-freedom robotic arm is connected to a welding torch.

[0037] In a further optimization of the above embodiment, a collection box is placed on the ground between the two placement platforms 1. The collection box, the six-degree-of-freedom robotic arm, and the welding torch are not shown in the figure. The six-degree-of-freedom robotic arm is existing technology and its working principle will not be described.

[0038] It should be noted that the belt drive assembly 7 and the six-degree-of-freedom robotic arm are both electrically connected to the controller, which is not shown in the figure.

[0039] The working process of this utility model:

[0040] First, place two water supply pipes of the same size into the V-shaped grooves 2 one after the other from one side of the two placement platforms 1 (the left water supply pipe is placed from the left side of the left placement platform 1, and the right water supply pipe is placed from the right side of the right placement platform 1). The water supply pipes will then come into contact with the first rotating roller 5 (as per the instruction manual). Figure 2 As shown in the figure, the placement position of the two water supply pipes can be quickly defined, that is, the docking end faces of the two water supply pipes are now in a state of accurate alignment. Then, with the help of hydraulic equipment, the two water supply pipes can be pushed synchronously towards the center. When the distance between the docking end faces of the two water supply pipes reaches the preset value range, the pushing will stop (at this time, the water supply pipes can be placed stably, that is, both ends extend to one side of the placement platform).

[0041] Then, the welding torch is driven by a six-degree-of-freedom robotic arm to perform local welding on the joint between the two water supply pipes. After the local welding is completed, the controller controls the four sets of belt drive components 7 to start simultaneously (two sets of belt drive components 7 are set on one placement platform 1 so that the two first rotating rollers 5 on the same placement platform 1 rotate in the same direction. When the four belt drive components 7 are started, the entire water supply pipe can be rotated in place to change different parts for subsequent circumferential welding. After the water supply pipe position is changed, the six-degree-of-freedom robotic arm and welding torch can be used again to weld other areas. Finally, the circumferential welding process of the water supply pipe joint is completed, thus completing the processing. After the circumferential welding process is completed, the water supply pipe can be unloaded from one side of one of the placement platforms 1. The debris and impurities generated during the welding process can be collected in the collection box in time for easy subsequent cleaning.

[0042] Compared to existing technologies, this device can quickly define the position of two water supply pipes of the same size and specifications, and thus the docking end faces of the two water supply pipes can be quickly and accurately aligned. At the same time, after completing the local automatic welding of the water supply pipe docking position, the welding area can be automatically changed without the need for manual assistance to rotate the water supply pipes, thus the whole welding process is more effective.

[0043] In some embodiments, such as Figure 3 and Figure 4 As shown, each placement platform 1 is fixed with a pressing component, and the pressing component is connected to a V-shaped plate 10 located directly above the V-shaped groove 2. The second mounting groove is symmetrically opened on the V-shaped plate 10, and a second rotating roller 11 is rotatably connected inside the second mounting groove. The bottom end of the second rotating roller 11 is outside the second mounting groove, and the top end of the second rotating roller 11 is spaced apart from the top of the second mounting groove (specifically, a third rotating shaft is rotatably connected inside the second mounting groove, and a second rotating roller 11 is provided outside the third rotating shaft; the second mounting groove and the third rotating shaft are not shown in the figure).

[0044] In a further refinement of the above embodiment, the pressing component includes a mounting frame 8 and a telescopic component 9. Each placement platform 1 is equipped with a U-shaped mounting frame 8, and the mounting frame 8 is provided with a telescopic component 9, which is connected to a V-shaped plate 10. In this embodiment, the pressing component, in conjunction with the V-shaped plate 10 and the second rotating roller 11, can make the water supply pipe more stable during the process of rotating and changing the welding area in place.
