Adjusting tool for machining irregular-thickness flange faces of engine pipe fitting parts

The utility model discloses an adjusting tool for machining an irregular-thickness flange face of an engine pipe fitting part, which comprises a fixed base plate used for being connected with a machine tool and a movable base plate arranged above the fixed base plate, and a clamping and positioning assembly used for clamping a part to be machined is arranged on the movable base plate. Adjusting screws which are perpendicular to the fixed base plate, are axially limited and can rotate in the circumferential direction are arranged on the four corners of the fixed base plate, and the adjusting screws are in threaded connection with the movable base plate. The utility model solves the problem that the processing tool is not easy to adjust, shortens the preparation time of the tool and the manufacturing difficulty of the tool, and has obvious effects on ensuring the processing quality and the production efficiency of irregular special-shaped flange surfaces such as engine pipe fittings. 本实用新型公开了一种用于加工发动机管件类零件不规则厚度
