Description

Technical Field

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

[0002] Flange is also called flange flange or flange. Flange is a part that connects shafts to each other and is used to connect pipe ends. It is also used as flange on equipment inlet and outlet to connect two devices. Flange fixture assembly is a special fixture used when processing flange.

[0003] When processing the existing flange, it is necessary to first place the flange in the lower clamp, and then put the upper clamp on the upper end of the flange. When the upper clamp and the lower clamp are fitted together, the two clamp components are fixed with screws, and then the internal flange is processed. This method is not only time-consuming and labor-intensive, but also has low efficiency in fixing the flange. At the same time, the screws are prone to loosening when the flange is processed, resulting in a decrease in the accuracy of the flange processing and affecting the quality of the flange product.

[0004] To this end, we propose a flange fixture assembly for flange processing. Utility Model Content
