[0001] The utility model relates to the technical field of mechanical fixtures, in particular to a flange milling fixture which is convenient for disassembly and assembly. Background Technique

[0002] A flange, also known as a flange convex disc or a flange. A flange is a part used for connecting shafts to each other and is used for connecting between pipe ends; there are also flanges used at the inlets and outlets of equipment for connecting between two pieces of equipment, such as a reducer flange. A flange connection or a flange joint refers to a detachable connection formed by connecting a flange, a gasket and bolts together as a set of combined sealing structures. A pipe flange refers to a flange used for piping in a piping device, and when used on equipment, it refers to the inlet and outlet flanges of the equipment. There are holes in the flange, and bolts tightly connect the two flanges.
