[0035] like Figure 1-4 As shown, the rotary welding device for straight pipe assembly based on assembly line construction includes a workbench 1, two bases 2, two supports 3, and a rotating mechanism 4. The two bases 2 are fixed on both sides of the workbench 1, and the two supports 3 are fixed on both ends of the bases 2. The rotating mechanism 4 is movably mounted on the supports 3, and there are multiple rotating mechanisms 4 arranged in parallel. The two pipe fittings 8 to be welded can be placed on the two rotating mechanisms 4. The rotating mechanism 4 realizes the synchronous rotation of the pipe fittings 8 until the pipe fittings 8 complete the full circumferential welding.

[0036] In this embodiment of the present invention, the base 2 is a square structural steel of 1250mm×50mm×50mm.

[0037] In this embodiment of the present invention, the support 3 is an L-shaped equilateral angle steel with dimensions of 270mm (length) × 20mm (limb width) × 5mm (thickness).

[0038] Please refer to the following for details. Figure 2 Each rotating mechanism 4 includes a support shaft 401, a rotating main shaft 402, and multiple rotating components 403. The support shaft 401 is fixedly mounted on the support 3. The rotating main shaft 402 is sleeved on the outside of the support shaft 401. The rotating components 403 are located between the rotating main shaft 402 and the support shaft 401 to enable the rotating main shaft 402 to rotate. The rotating components 403 are located at both ends of the rotating main shaft 402. The inner wall of the rotating component 403 is fixedly connected to the support shaft 401, and the outer wall is fixedly connected to the rotating main shaft 402. That is, the rotating main shaft 402 rotates relative to the support shaft 401 through the rotating components 403, thereby driving the two pipe fittings 8 located on the rotating main shaft 402 to rotate synchronously. This optimizes the operation process for on-site welding workers who need to move back and forth when welding pipe fittings 8. The welding of pipe fittings 8 can be completed simply by rotating the rotating main shaft 402 from a fixed position.

[0039] In this embodiment of the present invention, there are two rotating mechanisms 4, meaning that the device can only hold one set of pipe fittings 8 (two pipe fittings 8 make up one set) for the assembly welding of the pipe fittings 8. In other feasible embodiments of the present invention, the number of rotating mechanisms 4 is an even number, such as four, six, or eight, which can hold two, three, four, or more sets of pipe fittings 8 for the assembly welding of multiple sets of pipe fittings 8.

[0040] In this embodiment of the present invention, the support shaft 401 is a stainless steel tube with an outer diameter of φ9.8mm, a wall thickness of 1mm, and a length of 1310mm; the rotating spindle 402 is a seamless steel tube with an outer diameter of φ26.7mm, a wall thickness of 2.87mm, and a length of 1150mm.

[0041] In this embodiment of the present invention, the rotating component 403 is a bearing, preferably a deep groove ball bearing. The inner ring of the bearing is fixedly connected to the support shaft 401, and the outer ring is fixedly connected to the rotating main shaft 402, so as to realize that the rotating main shaft 402 rotates relative to the support shaft 401.

[0042] In this embodiment of the present invention, each rotating mechanism 4 has two rotating parts 403, which are fixed at both ends of the rotating main shaft 402.

[0043] Please refer to the following for details. Figure 1To ensure operational safety, the rotary welding device based on the assembly line construction straight pipe group also includes multiple flame-retardant protective sleeves 6. The protective sleeves 6 are fixedly sleeved on the outside of the rotary spindle 402, and at least two protective sleeves 6 are sleeved on the outside of each rotary spindle 402.

[0044] Furthermore, a gap of 70mm ± 0.3mm is left between the protective sleeves 6 on the same rotating spindle 402, and the middle gap area facilitates real-time observation of the weld formation quality.

[0045] In this embodiment of the present invention, the protective sleeve 6 is a PVC sleeve with a diameter of φ30mm, a wall thickness of 1mm, and a length of 455mm, preferably a UL94 V-0 grade flame-retardant PVC sleeve.

[0046] Please refer to the following for details. Figure 3 To enable the assembly and welding of pipe fittings 8 with different diameters, the assembly and welding device for straight pipe assembly based on the production line construction also includes a distance adjustment mechanism 5. The distance adjustment mechanism 5 is located at both ends of the rotating mechanism 4 and is used to adjust the distance between the rotating mechanisms 4 so as to adapt to pipe fittings 8 with different diameters. Specifically, the distance adjustment mechanism 5 includes a first adjustment groove 501, a second adjustment groove 502, a connector 503, and a locking member 504. The first adjustment groove 501 and the second adjustment groove 502 are both located on the support 3. The support shaft 401 passes through the first adjustment groove 501 and extends outward at its end. The connector 503 is located on the support shaft 401 and is located in the second adjustment groove 502. The locking member 504 is located on the connector 503 and can be tightly attached to the support 3 to fix the support shaft 401.

[0047] In this embodiment of the present invention, the connecting member 503 is a bolt and the locking member 504 is a nut. By tightening the nut, the nut is pressed tightly against the upper surface of the support 3 to fix the support shaft 401.

[0048] In this embodiment of the present invention, the support shaft 401 has a φ7.8mm through hole at a position of about 45mm from each end as a positioning reference for assembling the connector 503.

[0049] In this embodiment of the present invention, the first adjustment groove 501 and the second adjustment groove 502 are respectively provided on both sides of the support 3.

[0050] In this embodiment of the present invention, the first adjusting groove 501 and the second adjusting groove 502 are elongated oval grooves.

[0051] Please refer to the following for details. Figure 1 A caster wheel 7 is installed under the workbench 1. The caster wheel 7 is preferably a caster wheel 7 with a brake, so that the device can turn freely without adjusting the overall direction.

[0052] It should be noted that all standard parts used in this application can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0053] This utility model is a rotary welding device for straight pipe assemblies based on assembly line construction. Its working principle is explained with reference to the accompanying drawings:

[0054] Before welding the pipe fitting 8, it needs to be adjusted according to the diameter of the pipe fitting 8 to be welded. Loosen the locking part 504 on the branch 3, move the support shaft 401 along the first adjustment groove 501 to the diameter position of the target pipe fitting 8, and then re-lock the locking part 504. Place the pipe fitting 8 to be welded horizontally on the support surface of the protective sleeve 6, and adjust it so that the axis of the pipe fitting 8 is parallel to the rotating main shaft 402.

[0055] During welding, the operator welds on one side of the welding center axis. After completing the current welding section, the pipe fitting 8 is manually rotated. The transmission system of the rotating spindle 402 and the rotating part 403 enables the synchronous rotation of another pipe fitting 8 until the full circumferential welding is completed. Then, the next set of pipe fittings is replaced to achieve assembly line construction.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
