Description

Technical Field

[0001] The utility model relates to the technical field of air duct welding positioning, in particular to a pipe body positioning device for welding air duct processing. Background Art

[0002] At present, when welding the traditional Y-type welded air duct, first, the staff places one of the pipes on the welding platform, and then adjusts the angle. After the angle adjustment is completed, it is clamped and fixed by a clamping device. After clamping, the staff takes out the second pipe and splices the first pipe. After the splicing is in place, the staff holds the welding gun with the other hand and performs partial spot welding on the welding point. After spot welding, the last set of pipes are docked with it, and then spot welding is performed. After spot welding, the three sets of pipes can be fully sealed.

[0003] Because, when welding, two groups of pipes are first butted together and spot-welded, and then another group of pipes are butted together and spot-welded. This welding method is prone to the first two groups of pipes being misaligned due to welding, so that the third group of pipes cannot be perfectly butted together with the first two groups of pipes during welding, resulting in gaps at the joints after welding. When used later, air may leak through the gaps, affecting the sealing performance of the system and also causing noise problems. Utility Model Content

[0027] By sliding the arc-shaped I-shaped block 31 in the clamping and positioning assembly 3 in the T-shaped ring groove 2, the positions of the forward moving component 33 and the inner clamping component 34 on the disc 1 are changed, thereby facilitating the later splicing of different Y-shaped air ducts, T-shaped tubes, straight tubes and cross-shaped air ducts, and facilitating the later welding.

[0030] Embodiment 2

[0031] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0034] Embodiment 3

[0035] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0036] The lifting support assembly 5 includes a rectangular sleeve 51, the middle of the top surface of the disc 1 is fixedly connected with the rectangular sleeve 51, the interior of the rectangular sleeve 51 is slidably connected with a lifting rod 52, and the top surface of the lifting rod 52 is fixedly connected with a circular placement disc 53.

[0037] The lifting threaded rod 55 in the lifting support assembly 5 drives the lifting rod 52 and the circular placement plate 53 to move up and down, so that the air duct 4 can be supported, and the welding position can also be supported so that the force is applied during welding to cause deformation at that position.

[0038] The working principle and use process of this utility model:

[0039] In use:

[0040] When in use, firstly, the air duct 4 to be welded is sleeved on the outside of the clamping jaws 347, and then the clamping threaded rod 345 is rotated. When the clamping threaded rod 345 is rotated, the collar 348 will be driven to slide on the surface of the cylinder 342, and as the collar 348 moves, the connecting rod 3410 will be driven to rotate at a certain angle, and as the connecting rod 3410 rotates, the clamping jaws 347 will be pushed to slide in the sliding groove 346, and as the clamping jaws 347 slide, the four groups of clamping jaws 347 will move outward, thereby clamping and fixing the air ducts 4 with different inner diameters, and when one group is clamped and fixed, the remaining inner clamping parts 34 are clamped and fixed in the same way;

[0041] After clamping and fixing, according to the shape of welding, for example, in the case of Y-shaped air duct, three sets of clamping and positioning components 3 are placed on the disc 1 at a certain angle. When placing, first, move the forward moving component 33, and the forward moving component 33 will drive the arc-shaped I-shaped block 31 to slide in the T-shaped ring groove 2. When the forward moving component 33 moves, it will also drive the inner clamping component 34 and the air duct 4 to move, so that the multiple sets of air ducts 4 are moved to the appropriate position, and the multiple sets of air ducts 4 can form a Y shape.

[0042] When it moves to the position, at this time, the forward threaded rod 332 is rotated, and when the forward threaded rod 332 rotates, the inner clamping part 34 is driven to move. When the inner clamping part 34 moves, several groups of air ducts 4 can be spliced ​​together to form a new group of complete air ducts 4;

[0043] After splicing, at this time, rotate the lifting threaded rod 55. As the lifting threaded rod 55 rotates, it drives the circular placement plate 53 to move downward. When the circular placement plate 53 moves upward, it will contact the surfaces of multiple groups of air ducts 4, thereby supporting the air ducts 4, facilitating later welding and preventing deformation that makes the gap larger and inconvenient for later welding.
