[0002] Special-shaped flanges (100) are widely used in large containers in the fields of aerospace, petroleum, and chemical engineering. Due to their large size, special-shaped flanges are usually divided into several arc segments for processing, assembled into a full circle, and processed on a vertical lathe to the designed shape and size. Finally, they are transported to the construction site, and then several arc segments are welded together to form a complete special-shaped flange and welded to the pressure vessel.

[0003] Since special-shaped flanges are large in size and have various shapes, the clamping angle needs to be temporarily adjusted during the processing. Generally, the clamp angle is not easy to adjust, and unstable clamping can easily cause slippage.

[0004] For this reason, our company provides a special-shaped flange clamping claw to solve the above problems. Utility Model Content

[0007] A special-shaped flange clamping claw includes a fixed seat and a clamping seat. The clamping seat includes a trapezoidal plate. A rotating column is fixed to the bottom of the trapezoidal plate. Adjustment seats are provided on both sides of the trapezoidal plate and are arranged at an angle to the trapezoidal plate. The adjustment seats are provided with a slide groove. A clamp is provided at the top of the slide groove. A slider is provided at the bottom of the clamp that extends into the slide groove and matches the slide groove. The adjustment seat and the slider are connected by fasteners.

[0008] The fixing seat is provided with multiple rotating grooves matching the rotating column. The side wall of the fixing seat is provided with a fixing hole connected to the rotating groove. The fixing hole is threaded with a fixing bolt A. The fixing seat is connected to the rotating column of the clamping seat through the fixing bolt A.

[0009] Preferably, the adjustment seat and the slider are fixed together by a fastener, and the fastener includes a threaded hole located on the side wall of the adjustment seat and connected to the slide groove, and a fixing bolt B for fixing the slider is passed through the threaded hole.

[0010] Preferably, a groove is provided on the fixing seat at the bottom of the rotating tank, and the groove is adapted to the diameter of the rotating column.

[0011] Preferably, the fixing seat is provided with a plurality of fixing feet for installation.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] According to the outer diameter or inner diameter of the special-shaped flange, the direction of the clamping seat is determined. The clamping angle of the clamping seat can be adjusted by the deflection angle of the rotating column in the rotating groove. After adjustment, it is fixed with fixing bolt A. After determining the clamping angle, the slider is adjusted to a fixed position in the slide groove. The clamping point is accurately positioned again to ensure stable clamping, thereby solving the problem of large flange products slipping due to unstable clamping in the existing structure and limited processing.

[0019] A preferred embodiment of the present invention will be described below in conjunction with the accompanying drawings to clearly and completely describe the technical solution in the preferred embodiment of the present invention.

[0020] A special-shaped flange clamping claw includes a fixing base 1 and a clamping base 2. The clamping base 2 includes a trapezoidal plate 21. A rotating column 22 is fixed to the bottom of the trapezoidal plate 21. Adjustment bases 23 are provided on both sides of the trapezoidal plate 21 and are arranged at an angle to the trapezoidal plate 21. The adjustment base 23 has a slide groove 231. A clamp 24 is provided on the top of the slide groove 231. A slider 241 is provided at the bottom of the clamp 24, which extends into the slide groove 231 and matches the slide groove 231. The adjustment base 23 and the slider 241 are connected by fasteners.

[0021] The fixing seat 1 is provided with a plurality of rotating grooves 11 matching the rotating column 22. The side wall of the fixing seat 1 is provided with a fixing hole 12 connected to the rotating groove 11. The fixing hole 12 is internally threaded with a fixing bolt A121. The fixing seat 1 is connected to the rotating column 22 of the clamping seat 2 through the fixing bolt A121.

[0022] The utility model is designed according to Figure 3 or Figure 4The outer diameter or inner diameter shape of the special-shaped flange 100 determines the orientation of the clamping seat 2. The clamping angle of the clamping seat 2 can be adjusted by the deflection angle of the rotating column 22 in the rotating groove 11. After adjustment, it is fixed with the fixing bolt A121. After determining the clamping angle, the slider 241 is adjusted to a fixed position in the slide groove 231. The clamping point is accurately positioned again to ensure firm clamping, thereby solving the problem of slippage of large flange products and limited processing caused by unstable clamping in the existing structure.

[0023] Specifically, the adjustment seat 23 and the slider 241 are fixedly connected by a fastener. The fastener includes a threaded hole 3 located on the side wall of the adjustment seat 23 and connected to the slide groove 231. A fixing bolt B31 for fixing the slider 241 is installed in the threaded hole.

[0024] Through the above design, the slider 241 of the clamp 24 can be displaced in the slide groove 231. After the clamping point is determined, it is fixed with the fixing bolt B31, and the clamping position can be flexibly changed to ensure stable clamping.

[0025] Specifically, a groove 13 is formed on the fixing seat 1 at the bottom of the rotating groove 11 , and the groove 13 is adapted to the diameter of the rotating column 22 .
