[0050] Reference Figures 1 to 3In this embodiment, to address the shortcomings of existing technologies that require different tooling for limiting and fixing when welding multiple pipe fittings, this utility model provides a processing tooling for pipe welding. The processing tooling includes: a base 1, a worktable 2, multiple moving parts 3, two bidirectional propulsion parts 4, multiple limiting parts 6, and a linkage part. The base 1 is flat and is used to construct the processing plane and install the processing tooling. The worktable 2 is disposed on the base 1 and is used to support and bear the pipe fittings 5 ​​to be welded. The multiple moving parts 3 are disposed on the worktable 2 and are arranged in a circular array on the worktable 2. The moving parts 3 are used for centripetal movement on the worktable 2. The multiple limiting parts 6 are respectively disposed on the multiple moving parts 3 and are detachably connected to the moving parts 3. The multiple limiting parts 6 are arranged in a circular array on the worktable 2 and are respectively attached to the inner wall of the welded part. Specifically, the moving part 3 drives the limiting part 6 to move centripetally on the worktable 2, allowing the limiting part 6 to fit inside the welded pipe fitting 5, thereby achieving the limiting and fixing of two or more welded pipe fittings 5. The linkage part is disposed on the worktable 2, located between multiple moving parts 3, and multiple limiting parts 6 are distributed in a circular array along the linkage part. The linkage part is used to drive multiple moving parts 3 to perform linked centripetal movement. Two bidirectional propulsion parts 4 are disposed on the base 1, symmetrically arranged on both sides of the worktable 2. The closer ends of the two bidirectional propulsion parts 4 are connected to a moving part 3, wherein the moving direction of one moving part 3 is parallel to the propulsion direction of the two bidirectional propulsion parts 4. In this embodiment, the bidirectional propulsion unit 4 pushes a moving unit 3, which in turn drives another moving unit 3 via a linkage unit. This, in turn, causes multiple moving units 3 to move their respective limiting units 6 in a centripetal motion, allowing the limiting units 6 to conform to the inner walls of the multiple welded pipe fittings 5. This effectively positions and limits the multiple welded pipe fittings 5 ​​without requiring excessive tooling for limiting and fixing them. In other words, it effectively solves the problem in existing technologies where different tooling is needed for limiting and fixing multiple pipe fittings during welding.

[0051] Reference Figure 2 and Figure 3In this embodiment, three moving parts 3 may be provided, and the three moving parts 3 are arranged in a circular array on the worktable 2. For ease of description of the structure of the moving parts 3, one moving part 3 is used as an example. Specifically, one moving part 3 includes: a slide rail 31, a slider 311, a moving block 32, and a mounting block 33. The slide rail 31 is provided on the worktable 2 and is used for orientation. The slider 311 is slidably disposed on the slide rail 31. The moving block 32 is connected to the slider 311 and is slidably connected to the slide rail 31 through the slider 311, so as to enable the moving block 32 to perform centripetal movement on the slide rail 31. The mounting block 33 is disposed on the moving block 32 and is detachably connected to the moving block 32 by bolts. The limiting part 6 is disposed on the mounting block 33. In this embodiment, the moving block 32 slides on the slide rail 31 via the slider 311, thereby enabling the limiting part 6 mounted on the mounting block 33 to move centripetally towards or away from the slide rail 31, thus limiting the welded pipe fitting 5. It should be noted that in this embodiment, to allow the moving part 3 to drive the limiting part 6 to move centripetally towards or away from the limiting part 6, the slide rails 31 of the multiple moving parts 3 are arranged in a circular array on the worktable 2, with one end of the extended lines of the multiple slide rails 31 intersecting, meaning one end of the multiple slide rails 31 is close to each other. Furthermore, the number of the moving parts 3 and the limiting part 6 can be set according to actual conditions, which will not be elaborated further here.

[0052] Reference Figure 2 and Figure 3 In this embodiment, to facilitate understanding of how the linkage unit drives multiple moving parts 3 to move in tandem, the structure of the linkage unit is described below. Specifically, the linkage unit includes: a linkage member 7, three connecting rods 71, and a connecting shaft 72. The linkage member 7 is triangular in shape, and the apex of the triangle of the linkage member 7 is connected to the three moving blocks 32 respectively. The three connecting rods 71 ​​are respectively disposed at the apex of the triangle of the linkage member 7, and the linkage member 7 is connected to the three moving blocks 32 respectively through the three connecting rods 71. The connecting shaft 72 is disposed on the worktable 2, and the linkage member 7 is rotatably connected to the connecting shaft 72. That is, in this embodiment, by moving one moving block 32, the moving block 32 drives the linkage member 7 to rotate through the connecting rod 71, and then the linkage member 7 drives the other moving blocks 32 to move centripetally on the slide rail 31 through the other two connecting rods 71, so as to realize the linkage of the three moving blocks 32.

[0053] Reference Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, two bidirectional propulsion units 4 are symmetrically arranged on both sides of the workbench 2. The ends of the two bidirectional propulsion units 4 that are close to each other are connected to a moving block 32. The two bidirectional propulsion units 4 have opposite propulsion directions, thereby driving the same moving block 32 to perform reciprocating centripetal motion, which in turn enables the welding pipe fitting 5 to be limited, fixed, and released. For ease of description, this is described using one bidirectional propulsion unit 4. Specifically, one bidirectional propulsion unit 4 includes: a mounting base 41, a propulsion member 42, and a connecting frame 43. The mounting base 41 is disposed on the base 1 and is located on one side of the workbench 2. The propulsion member 42 is disposed on the mounting base 41, and its propulsion end penetrates through the mounting base 41. The connecting frame 43 is disposed on the propulsion end of the propulsion member 42 and is connected to one of the moving blocks 32. In this embodiment, the pushing end of the pusher 42 pushes the connecting frame 43, causing the connecting frame 43 to move the moving block 32. Then, the moving block 32, through the linkage 7, moves other moving blocks 32, thereby enabling the limiting part 6 mounted on the mounting block 33 to perform a centripetal limiting movement. It should be noted that, to ensure proper linkage, the lengths of the connecting frames 43 in the two bidirectional pushers 4 are not identical; that is, the lengths of the two connecting frames 43 can be set according to actual needs. Furthermore, the pusher 42 can be any one of a pneumatic push rod, a hydraulic push rod, or an electric push rod.

[0054] Reference Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, three limiting parts 6 are provided. These three limiting parts 6 are respectively connected to three moving parts 3 via mounting blocks 33, and the limiting parts 6 are fitted into the interior of the welded pipe fitting 5. For ease of description, the structure of the limiting parts 6 is described using a single limiting part 6. Specifically, one limiting part 6 includes a limiting rod 61 and a limiting connector 62. The limiting rod 61 is disposed on the mounting block 33 and can be detachably connected to the mounting block 33 via bolts. The limiting connector 62 is disposed on the limiting rod 61, located away from the mounting block 33, and can be connected to the limiting rod 61 via bolts. The limiting rod 61 and the limiting connector 62 are respectively fitted into the inner wall of the welded pipe fitting 5 to achieve centripetal limiting and fixing of the welded pipe fitting 5. In this embodiment, by installing the limiting rod 61 and the limiting connector 62 onto the mounting block 33, and by having the limiting rod 61 and the limiting connector 62 abut against the inner wall of the pipe fitting 5 to be welded, the pipe fitting 5 can be limited and fixed. It should also be noted that in this embodiment, the design length of the limiting rod 61 and the limiting connector 62 can be designed according to the welding requirements of the pipe fitting 5, which will not be elaborated further here.
