Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to an adaptive splicing fixture for connecting pipes. Background Technology

[0002] The connecting pipe consists of a central pipe body and flanges welded to both ends. This type of connecting pipe is a specialized pipeline, produced in large quantities, and has high standardization requirements. With economic development and continuous improvement in efficiency, demands for work efficiency have also been placed on it.

[0003] Currently, these specialized connecting pipes are generally manufactured using a scribing and splicing method. However, this splicing process cannot guarantee the parallelism of the flanges at both ends and the coaxiality of the connecting holes on the flanges, resulting in very low manufacturing efficiency. Furthermore, because the parallelism of the flanges at both ends and the coaxiality of the connecting holes on the flanges cannot be guaranteed, product interchangeability is poor during subsequent maintenance, making it difficult to replace with new connecting pipes and causing many problems for on-site installation.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Example 1:

[0041] like Figures 1 to 4 As shown, this utility model provides an adaptive splicing fixture for connecting pipes, including a frame 1. Movable support devices are provided at both ends of the frame 1, and multiple fixed support devices are provided in the middle of the frame 1. In this embodiment, the frame 1 is a long frame structure. The frame is welded and then machined as a whole to ensure the connection dimensions at both ends. Movable support frame mounting seats 101 are fixed at both ends of the frame 1, and multiple staggered movable support frame mounting seats 101 and V-block mounting seats 102 are fixed in the middle of the frame 1. The movable support frame mounting seats 101 are used to install movable support frames 2, and the V-block mounting seats 102 are used to install the fixed support devices. The positions of the movable and fixed support devices are installed according to actual needs, forming a support mechanism with movable support devices at both ends and multiple fixed support devices in the middle.

[0042] Combination Figure 4 As shown, the fixed support device includes a V-block 3, a limiting plate 5, and a flat needle roller bearing 4. The limiting plate 5 is placed on the V-block mounting base 102, and the V-block 3 is placed on the limiting plate 5. The limiting plate 5 has multiple square through slots, and multiple flat needle roller bearings 4 are installed in the corresponding slots of the limiting plate 5. The limiting plate 5 is slightly thinner than the flat needle roller bearing 4, allowing the V-block 3 to suspend above the limiting plate 5. The upper and lower sides of the flat needle roller bearing 4 contact the V-block 3 and the V-block mounting base 102, respectively. The roller axis of the flat needle roller bearing 4 is parallel to the length direction of the frame 1, allowing the V-block 3 to slide in a direction perpendicular to the length of the frame 1.

[0043] In addition, the V-block 3, the limiting plate 5, and the two ends of the V-block mounting base 102 are connected to the frame 1 together by bolts 301. The through hole on the V-block 3 is an oblong hole; the bolts 301 do not need to be tightened too much during fixing, allowing the V-block 3 to be easily pushed within the oblong hole along the rolling direction of the flat needle roller bearing 4. In this embodiment, the V-block 3 can be finely adjusted using this structure to compensate for straightness errors in the tube body 11 during rolling.

[0044] After each V-block 3 is assembled, it is used to support the pipe body 11 that needs to be joined. The upper end of the V-block 3 has a V-shaped opening, the bottom of the V-shaped opening has a groove, and there is an arc-shaped surface on both sides of the V-shaped opening. The arc-shaped surface has the same outer diameter as the pipe body 11, and the central axis of the arc-shaped surface is basically at the same horizontal plane as the flange 12 located on the movable support device at both ends.

[0045] Combination Figure 1 , Figure 2 and Figure 5 As shown, the movable support device includes a movable support frame 2 that is slidably installed along the length of the frame 1. The movable support frame 2 has multiple positioning pins 202 on the side near the V-block 3, and the flange 12 is positioned on the positioning pins 202. The movable support devices at both ends are symmetrical in structure.

[0046] The sliding installation structure of the movable support frame 2 is as follows: A connecting hole is opened at each of the four corners of the movable support frame mounting base 101. The movable support frame mounting frame 9 is mounted on the movable support frame mounting base 101. Baffles 10 are respectively provided at both ends of the movable support frame mounting frame 9. The baffles 10, the movable support frame mounting frame 9, and the movable support frame mounting base 101 are fixed together to the frame 1 with bolts. A parallel linear guide rail 8 is fixed to each side of the movable support frame mounting frame 9, and the linear guide rail 8 is located between the baffles 10 at both ends. A row of threaded holes for fixing the linear guide rail 8 is opened on each side of the movable support frame mounting frame 9. A slider 7 is slidably mounted on the linear guide rail 8. The two ends of the movable support frame 2 are respectively fixed to the slider 7 on both sides. The baffles 10 prevent the slider 7 from detaching from the linear guide rail 8.

[0047] Example 2:

[0048] Based on the above embodiment one, combined with Figures 1 to 3As shown, in this embodiment, the positioning plate 203 is fixed to the side of the movable support frame 2 near the V-block 3, and four positioning pins 202 arranged in a square are fixed to the side of the positioning plate 203. The diameter of the positioning pins 202 is smaller than the connecting holes on the flange 12. In use, the flange 12 is positioned on the positioning pins 202, that is, the connecting holes on the flange 12 are fitted onto the positioning pins 202. Quick-pressing devices 6 are fixed on both sides of the positioning plate 203, and the quick-pressing devices 6 press against the edge of the flange 12 to press the flange 12 against the side of the positioning plate 203. The quick-pressing device 6 is prior art, and this embodiment does not impose further limitations.

[0049] A clearance hole is provided in the middle of the positioning plate 203. Two stops 201 are provided in the clearance hole and are fixed to the side of the movable support frame 2. In use, the end of the pipe 11 can enter the clearance hole and abut against the stop 201 to achieve the positioning of the relative position of the pipe 11 and the flange 12.

[0050] Working principle:

[0051] Combination Figure 1 and Figure 6 As shown, first fix the flanges 12 at both ends of the required splicing point to the movable support frames 2 on both sides, and then hoist the middle pipe body 11 onto the V-block 3;

[0052] Push the movable support frames 2 at both ends so that the two ends of the pipe body 11 are inserted into the inner hole of the flange 12;

[0053] Since the V-block 3 in the middle can be adaptively adjusted according to the force on the tube 11, the tooling is convenient to use and has good positioning accuracy.

[0054] This fixture ensures that the connection holes of the flanges at both ends are coaxial through the positioning pins on the movable support frames at both ends, making the connection standard of the flanges and pipes uniform. Moreover, the flanges can be quickly tightened using the positioning pins and quick clamping device. The process is simple and convenient, saving auxiliary time. This allows one person to complete the splicing of the entire connecting pipe in a few minutes, which not only improves production efficiency but also product quality.

[0055] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
