Description

Technical Field

[0001] The utility model relates to the technical field of flange processing, in particular to a clamp device for flange processing. Background Art

[0002] A flange is a disc-shaped part that is most common in pipeline engineering. It is used to connect pipes, pipe fittings, or equipment through a flange and bolt connection. More broadly speaking, any connection part that relies on a flange structure to connect two planes and is closed by bolts is generally called a "flange." During the flange processing process, a clamp is required to fix it. The existing clamp device cannot fix flanges of different sizes during use, and cannot drive the flange to rotate. It can only process one side of the flange. When processing the other side, it needs to be manually flipped and re-fixed, which is inefficient and affects the use effect.

[0003] According to a flange processing fixture device published on the patent website (authorization announcement number: CN215748741U), the flange processing fixture device includes a "clamp base, a roller, a clamping ring", etc. to clamp the flange.

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] The flange processing fixture device uses a fixture base, a roller, a clamping ring, etc. to clamp the flange.

When the other side of the flange needs to be processed, the staff needs to manually remove the flange, turn it over and re-fix it. The operation is complicated and inefficient. Therefore, this device needs to be improved. Utility Model Content
