Technical Field

[0001] The utility model relates to the technical field of flange welding, in particular to a boiler flange welding tool. Background Art

[0002] Flange, also known as flange flange or flange, is a part used to connect shafts to each other. It is mainly used for connecting pipe ends. When the boiler room is built, flanges are also needed to connect the pipes in the boiler room. At the same time, welding tooling is required when welding the flange.

[0003] A search revealed Chinese patent number CN217394135U, which discloses a welding fixture for a boiler flange. The fixture comprises a base, a hollow support disc at the top of the base, a screw rotatably connected between the two ends of the support disc, one end of the screw being connected to a first knob, and sliders threadedly connected to the sidewalls of the screw. The two sliders are symmetrically arranged about the middle of the screw, and the threads on the sidewalls of the screw are rotated in opposite directions. The bottom of the slider abuts against the inner bottom of the support disc, and a locating pin is detachably connected to the top of the slider for inserting into the connecting hole of the flange. The top of the support disc is provided with an avoidance groove for avoiding the locating pin. A clamping mechanism for clamping the pipe is provided above the support disc. The clamping mechanism comprises a mounting ring, a clamping block, and a first adjusting rod. The clamping block is displaced by turning the first adjusting rod to achieve clamping or loosening. The utility model is adaptable to welding flanges and pipes of different specifications, has high applicability, and is very convenient to use.

[0004] In the above-mentioned patent documents, a clamping mechanism and a pressing mechanism are set on the support plate to clamp and limit the flange during welding. After the flange is welded and the pipe is welded with other components above, hot spatter will be generated at the welding point above the pipe, and some of the spatter will splash downward. After long-term use, the spatter splashing downward will cause certain damage to the pressing mechanism below. Therefore, a protective welding tooling is needed to protect the pressing mechanism below. Summary of the Invention

[0031] See also Figure 1-Figure 4 As shown, this embodiment is a boiler flange welding tool, comprising:

[0032] The welding fixture assembly includes a support plate 11 and a clamping mechanism 14. The clamping mechanism 14 is fixed to the top surface of the support plate 11.

[0033] The support plate 11 is used for connecting the clamping mechanism 14 , and the pressing mechanism 13 limits the position of the pipeline.

[0034] The protective assembly includes a fixing ring 21, a connecting ring 22, a connecting block 23 and a protective cover 24. The fixing ring 21 is fixed to the vertical surfaces of the clamping mechanisms 14 on both sides. The connecting ring 22 is rotatably connected to the outer side of the fixing ring 21. The connecting block 23 is fixed to the outer end of the connecting ring 22. The protective cover 24 is fixed to the outer end of the connecting block 23.

[0035] The fixing ring 21 is used for the connection and movement of the connecting ring 22 , the connecting ring 22 is used for the connection of the connecting block 23 , the connecting block 23 is used for the connection between the connecting ring 22 and the protective cover 24 , and the protective cover 24 protects the pressing mechanism 13 below.

[0036] The connecting ring 22 is provided with a connecting groove 211 at the rotation point with the fixing ring 21, and the edges on both sides of the top of the protective cover 24 are fixedly connected to the fixing frame 25;

[0037] The connecting groove 211 is used for the movement of the connecting ring 22 . The connecting ring 22 rotates on the surface of the fixing ring 21 through the connecting groove 211 . The fixing frame 25 is used for the connection of the magnetic block 26 .

[0039] The fixing frame 25 is used to connect the connecting plate 28 and the fixing ring 21 , and the magnetic block 26 is attracted to the connecting plate 28 , so that the connecting plate 28 limits the rotating protective cover 24 through the magnetic block 26 .

[0042] Working principle: Before use, the protective cover 24 is located outside the clamping mechanism 14. Therefore, when in use, the protective cover 24 is rotated by hand, and the connecting ring 22 is rotated in the connecting groove 211 on the surface of the fixing ring 21, so that the protective cover 24 is rotated toward the inside of the clamping mechanism 14 through the connecting block 23 and the connecting ring 22. At this time, the magnetic block 26 is away from the connecting plate 28, and then the protective cover 24 is rotated to above the clamping mechanism 13. At this time, the magnetic block 26 on the other side of the protective cover 24 is adsorbed with the other end of the connecting plate 28, so that the connecting plate 28 limits the rotated protective cover 24 through the magnetic block 26. When welding above the pipeline, spatter will splash onto the protective cover 24, and the protective cover 24 isolates the spatter from the clamping mechanism 13, so that the protective cover 24 protects the clamping mechanism 13 and prevents the spatter from damaging the clamping mechanism 13.
