[0001] This utility model relates to a general-purpose branch pipe assembly platform, belonging to the field of branch pipe assembly technology. Background Technology

[0002] There is a problem of poor positioning accuracy when assembling intersecting branch pipes and main pipes of tubular components. Due to the certain deviation in the cutting of the intersection line of the pipes, a local gap will be generated after intersecting with the main pipe, which will cause welding deformation. In order to avoid the above problems, a positioning splicing device is usually used during the splicing process.

[0003] Chinese utility model patent CN205600178U discloses a positioning and splicing device for intersecting branch pipes of tubular components. Its key feature is that it includes a base, a rotating platform on the base, a transversely arranged bed on the rotating platform, and a slide rail along the length of the bed on its top. A set of movable clamping devices is arranged opposite each other on the left and right sections of the slide rail. The movable clamping devices include a sliding base plate, a linear bearing, a clamping cylinder, a column, and a branch pipe connecting plate. This utility model's positioning and splicing device for intersecting branch pipes of tubular components has the advantages of making the branch pipe fit more tightly with the main pipe, resulting in a more uniform gap, reducing welding deformation, and lowering the labor intensity of assembly workers. However, in the prior art, when two branch pipes are located on both sides of the main pipe, and the two ends of the main pipe are connected to fixed insert plates, it is impossible to achieve relative fixation of the support plates and the main pipe, thus failing to meet practical application requirements.

[0007] The second positioning mechanism includes a second movable seat, which is slidably connected to the base along the length of the base. A positioning block is fixedly inserted into the second movable seat, and a socket is provided on the positioning block, into which a positioning pin is inserted.

[0008] Preferably, the second movable seat is provided with a groove, and the positioning block is disposed in the groove. The two sides of the positioning block along the length direction of the base are respectively attached to the inner walls of the groove along the length direction of the base.

[0028] like Figure 1-8 As shown, a general-purpose branch pipe assembly platform in this embodiment includes a base 1. The base 1 is provided with a first positioning mechanism 2 and two second positioning mechanisms 3. The two second positioning mechanisms 3 are symmetrically arranged along the length direction of the base 1. The first positioning mechanism 2 is located between the two second positioning mechanisms 3. The first positioning mechanism 2 is used to realize the positioning of the branch pipe 7 and the main pipe 4. The second positioning mechanism 3 is used to realize the positioning of the main pipe 4 and the support plate 5.

[0029] Two support plates 5 are inserted and fixed at both ends of the main pipe 4, and through holes 6 are provided on the support plates 5. Two branch pipes 7 are fixedly connected to the middle of the main pipe 4. The two branch pipes 7 are located on both sides of the main pipe 4 and are perpendicular to the main pipe 4. One end of the branch pipe 7 is fixed to the main pipe 4, and the other end of the branch pipe 7 is pre-fixed with a flange 8. During the splicing process, two second positioning mechanisms 3 correspond one-to-one with the two support plates 5 to fix the support plates 5. Then, the main pipe 4 is placed between the two support plates 5, and the main pipe 4 is parallel to the base 1. The two support plates 5 are inserted and fixed at both ends of the main pipe 4. Then, the support plates 5 and the main pipe 4 are welded and fixed to achieve the splicing of the support plates 5 and the main pipe 4. Next, the flange 8 of the branch pipe 7 is fixed by the first positioning mechanism 2, and the end of the branch pipe 7 away from the flange 8 is connected to the main pipe 4 to achieve the fixation of the branch pipe 7 and the main pipe 4. Then, the branch pipe 7 and the main pipe 4 are welded and fixed to achieve the splicing of the branch pipe 7 and the main pipe 4.

[0030] The first positioning mechanism 2 includes a first movable seat 21, which is slidably connected to the base 1 along the length of the base 1. A rotating seat 22 is provided on the first movable seat 21, which is rotatably connected to the first movable seat 21. The rotation center of the rotating seat 22 is arranged vertically. A guide rail 23 is fixedly provided on the rotating seat 22, which is arranged horizontally. Two positioning seats 24 are slidably connected on the guide rail 23 along the length of the guide rail 23. A positioning plate 25 is provided on the positioning seat 24, and a through groove 26 is provided on the positioning plate 25.

[0031] When the branch pipe 7 is spliced ​​with the main pipe 4, the flange 8 is fixed to the positioning plate 25 with bolts. The flange 8 has multiple connecting holes 9 in the circumferential direction. In fact, the number of through grooves 26 is equal to the number of connecting holes 9 and corresponds one-to-one. Specifically, there are eight through grooves 26 and connecting holes 9 in sequence. The end of the branch pipe 7 away from the flange 8 is connected to the main pipe 4, thus fixing the branch pipe 7 and the main pipe 4.

[0032] When the length of the branch pipe 7 changes, the positioning seat 24 can slide on the guide rail 23 to adjust the distance between the positioning plate 25 and the main pipe 4, which can be applied to the splicing of the main pipe 4 and branch pipes 7 of different lengths.

[0033] When the splicing angle between the branch pipe 7 and the main pipe 4 needs to be changed, the rotating seat 22 is rotated to realize the rotation of the positioning plate 25, that is, to realize the change of the splicing angle between the branch pipe 7 and the main pipe 4.

[0034] When the splicing position of branch pipe 7 needs to be changed, the first movable seat 21 can be moved on the base 1.

[0035] The second positioning mechanism 3 includes a second movable seat 31, which is slidably connected to the base 1 along the length of the base 1. A positioning block 32 is fixedly inserted into the second movable seat 31, and an insertion hole 33 is provided on the positioning block 32. A positioning pin 34 is inserted into the insertion hole 33.

[0036] The second movable seat 31 is provided with a groove 35, and the positioning block 32 is disposed in the groove 35. The two sides of the positioning block 32 along the length direction of the base 1 are respectively attached to the inner walls of the groove 35 along the length direction of the base 1.

[0037] The groove 35 is provided with a slot 36 on one side along the length direction of the base 1, and the positioning block 32 is provided with a protrusion 37 on one side. The protrusion 37 matches the slot 36 and is inserted into the groove 35.

[0038] When fixing the support plate 5, first pull out the positioning pin 34, place the support plate 5 on the positioning block 32, and then pass the positioning pin 34 through the through hole 6 and the insertion hole 33 in sequence. In fact, the through hole 6 and the insertion hole 33 are matched with the positioning pin 34, that is, the diameter of the through hole 6 and the diameter of the insertion hole 33 are equal to the diameter of the positioning pin 34. In this way, the horizontal positioning of the support plate 5 and the positioning plate 25 is achieved. The horizontal positioning of the positioning block 32 is achieved through the cooperation between the groove 35 and the positioning block 32 and the cooperation between the slot 36 and the locking block, that is, the horizontal positioning of the support plate 5 is achieved.

[0039] The number of insertion holes 33 on the positioning block 32 is two. In fact, the number of through holes 6 on the support plate 5 is two. The two insertion holes 33 correspond one-to-one with the two through holes 6.

[0040] Here, in fact, the end of the main pipe 4 is provided with a plug groove 10, the support plate 5 matches the plug groove 10, and the support plate 5 is inserted into the plug groove 10.

[0041] When using main pipes 4 of different lengths, the second movable seat 31 is slid on the base 1, and the distance between the two second movable seats 31 can be adjusted according to the length of the main pipe 4.

[0042] Of course, when there are two support plates 5 on the same end of the main pipe 4, and the two support plates 5 form a cross shape, the positioning block 32 and the second moving seat 31 are provided with corresponding slots to accommodate the protrusions when the two support plates 5 form a cross shape.

[0043] In summary, the main pipe 4 and the support plate 5 are relatively fixed, which facilitates the splicing between the main pipe 4 and the support plate 5 and meets the actual use requirements. Moreover, by rotating the rotating seat 22 and moving the first moving seat 21 and the second moving seat 31, it can be applied to splicing of different main pipe 4 lengths, different branch pipe 7 lengths, and different branch pipe 7 angles and positions.

[0044] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
