[0022] As shown in the figure, a special-shaped flange welding tool is used to Figure 1 The flange shown is tooled, and this type of flange is formed by welding a disc body 1 and a pipe body 2, wherein the disc body 1 is provided with a preset hole, which is used for bolt connection after being connected to the pipeline. The tooling of this application includes a base 3, and a positioning rod 4 is provided on the base 3. The positioning rod 4 is used to connect and fix the disc body 1. Specifically, after the disc body 1 is installed on the base 3, the positioning rod 4 is inserted into the preset hole to complete the constraint and fixation of the disc body 1.

[0023] Preferably, a mounting plate 5 is further included, a first adjustment slot 6 is provided on the base 3 in a transverse direction, the lower end of the mounting plate 5 is connected to the first adjustment slot 6 and the position is adjustable along the length direction of the first adjustment slot 6, and the mounting plate 5 is provided with a second adjustment slot 7 in a longitudinal direction. Specifically, the second adjustment slot 7 is perpendicular to the first adjustment slot 6.

[0024] Preferably, a clamping jaw is further included, which includes a fixed jaw 8 and a pressing jaw 9. The fixed jaw 8 and the pressing jaw 9 are both arc-shaped. The fixed jaw 8 and the pressing jaw 9 are assembled together to form a channel 10 for constraining the tube body 2. The axis of the channel 10 is in the same plane as the axis of the disc body 1. A connecting block 11 is provided on one side of the fixed jaw 8 and is rotatably connected to the second adjustment slot 7 through the connecting block 11 to adjust the angle of the channel 10 relative to the second adjustment slot 7. The position of the connecting block 11 is adjustable along the length direction of the second adjustment slot 7.

[0025] Since the adjustment of the clamping jaw and the second adjustment slot 7 cooperates with the first adjustment slot 6 to achieve two-dimensional adjustment of the clamping jaw position, the position range of the clamping jaw is greatly expanded to adapt to the clamping needs of tubes 2 of different lengths.

[0026] At the same time, the angle of the fixing claw 8 can be adjusted to adjust the channel 10 relative to the axis of the disc body 1, so as to adapt to the installation needs of the tube body 2 at different angles, thereby expanding the adaptability of the overall tooling.

[0027] Preferably, a first screw 12 is provided in the first adjustment groove 6 along the length direction, one end of the first screw 12 passes through the bottom of the mounting plate 5 and is rotatably connected to the base 3, and the first screw 12 is used to drive the mounting plate 5 to move along the axis direction of the first screw 12.

[0028] During use, by rotating the first screw 12, due to the sliding limit between the lower end of the mounting plate 5 and the first adjustment groove 6, the mounting plate 5 can be driven to move along the axis of the first screw 12, thereby realizing the lateral position adjustment of the clamping jaws.

[0029] Preferably, a second screw 13 is provided in the second adjustment slot 7 along the length direction, one end of the second screw 13 passes through the connecting block 11 and is rotatably connected to the mounting plate 5, and the second screw 13 is used to drive the connecting block 11 to move along the axis direction of the second screw 13.

[0030] During use, by rotating the second screw 13, due to the sliding limit between the connecting block 11 and the second adjustment groove 7, the connecting block 11 can be driven to move along the axis of the second screw 13, thereby realizing the longitudinal position adjustment of the clamping jaws.

[0031] Preferably, both ends of the pressing claw 9 extend outward to form a first connecting surface 14, and the fixed claw 8 forms a second connecting surface 15 corresponding to the first connecting surface 14. A limiting rod 16 is fixed on the first connecting surface 14, and the second connecting surface 15 corresponds to the limiting rod 16 to form a limiting hole 17. The end of the limiting rod 16 passes through the limiting hole 17 and is provided with a limiting plate 18. A spring 19 is wound around the limiting rod 16, and both ends of the spring 19 are respectively connected to the first connecting surface 14 and the second connecting surface 15 and are used to drive the first connecting surface 14 and the second connecting surface 15 to move toward each other.

[0032] After the tube body 2 passes through the channel 10, the spring 19 can keep the pressing claw 9 pressing the tube body 2, thereby keeping the tube body 2 stable during the welding process. At the same time, the setting of the limiting rod 16 and the limiting hole 17 can limit the moving direction of the pressing claw 9 to avoid the spring 19 causing the tube body 2 to return, so as to keep the position of the tube body 2 accurate and stable during the welding process.

[0033] Preferably, a mounting surface 20 is formed on one side of the fixing claw 8 , and a positioning hole 21 is provided on the mounting surface 20 . The positioning hole 21 is rotatably connected to the connecting block 11 through a bolt.

[0034] Preferably, the number of the positioning holes 21 is two and they are symmetrically arranged. An arc-shaped connecting groove 22 is provided on the connecting block 11 corresponding to the positioning holes 21 . The two positioning holes 21 are respectively connected to the two connecting grooves 22 by bolts.

[0035] The provision of the arc-shaped connecting groove 22 and the two positioning holes 21 can improve the stability of the mounting surface 20 after installation, and at the same time facilitate adjustment of the angle of the mounting surface 20 to adapt to the installation of the pipe body 2 at different angles.

[0036] Preferably, anti-slip strips 23 are provided on the inner sides of the fixing claw 8 and the pressing claw 9 .

[0037] The provision of the anti-slip strip 23 can further improve the stability of the tube body 2 after connection.
