Aircraft hanger and wing butt joint main joint precision device

The embodiment of the invention discloses an airplane hanging frame and wing butt joint main connector precision device which comprises a base, a supporting frame is fixedly connected to the top faceof the base, and a butt joint connector body is arranged at the top of the supporting frame. A specific three-axis tool is formed by connecting and combining the base and the supporting frame, and then a combined body of the butt joint connector body and the process boss is fixedly installed on the top face of the three-axis tool through the design that the counter bore and the threaded hole are movably connected with the positioning screw in a sleeved mode and in threaded connection with the positioning screw. Therefore, the problems of high machining cost, low efficiency and the like causedby the fact that the butt joint body is completely machined by five-axis equipment are solved, the main shaft torque rigidity of the three-axis machining equipment is basically unchanged relative to the five-axis equipment, th
