Abstract

The invention discloses measurement equipment and a measurement method and system for butt joint gaps and jumps of aircraft components. The measurement equipment comprises a positioning device, a measurement device and an upper computer; the positioning device comprises a positioning tool; the measurement device comprises an annular rail, a measurement head, a measurement head driving device and an annular rail driving device. The annular rail and the measurement head are arranged on the positioning tool so that the measurement head driving device can drive the measurement head to move along the annular rail, and the annular rail driving device can drive the annular rail to horizontally move on the positioning tool. Therefore, outline data of whole butt joint areas of the aircraft components to be measured can be measured through motion of the measurement head and the annular rail, and the defect is effectively overcome that since only local characteristic points are measured and measurement data is not comprehensive, the measurement precision is low; accordingly high-precision measurement on the butt joint gaps and jumps of the aircraft components to be measured is achieved.

Description

technical field [0001] The invention relates to the technical field of aircraft intelligent assembly, in particular to a measurement equipment, method and system for the butt joint gap and step difference of aircraft components. Background technique [0002] The outer surface of the aircraft is spliced ​​by many parts. The geometric accuracy of the splicing directly affects the aerodynamic continuity and electromagnetic continuity of the aircraft, and is an important indicator affecting the maneuverability, stealth and life of the aircraft. At present, aircraft assembly has changed from manual assembly to numerical control automatic assembly, and is moving towards intelligent assembly. For the assembly process of aircraft components, the automatic measurement of the gap and step difference in the docking area is the basis for attitude adjustment and trimming of CNC equipment, and it is also the key to the transformation of aircraft assembly to intelligence. [0003] In the ...
