Aircraft wing horizontal measurement device convenient to disassemble and assemble

Abstract

The invention relates to an aircraft wing horizontal measurement device convenient to disassemble and assemble. The device comprises a fixed base, a magnet block is embedded in the lower part of the fixed base; threaded grooves are formed in the upper portion of the fixed base. A mounting plate is fixedly connected to the top of the rotary table, a containing groove is formed in the middle of themounting plate, the lower portion of the mounting plate is sleeved with a pin shaft, a leveling instrument is mounted on the pin shaft and can rotate around the pin shaft, a clamping plate is hinged to one side of the front end of the mounting plate, and a clamping groove is fixedly formed in the other side of the front end of the mounting plate. The clamping plate is placed in the clamping groovefor ensuring a fact that the leveling instrument does not rotate out of the containing groove when measurement is not performed. The device is further provided with a supporting rod, and when the leveling instrument rotates around the pin shaft to be close to the horizontal state, the leveling instrument is supported below the leveling instrument through the supporting rod to accurately find thehorizontal position of the leveling instrument. The device is convenient to disassemble and assemble, good in flexibility and convenient to store and use.

Description

technical field [0001] The invention belongs to the technical field of aircraft assembly, and in particular relates to an aircraft wing level measuring device which is easy to assemble and disassemble. Background technique [0002] The level measurement of the aircraft refers to the measurement of the relative position accuracy of the various components of the aircraft when the aircraft is in a horizontal state. The accuracy of the relative position between components mainly includes the anhedral angle of the wing and empennage relative to the fuselage, the accuracy of the installation angle and the sweep angle, the deflection angle, fit, and fit clearance of each movable wing surface relative to the fixed wing surface The accuracy is worse than that of scissors, and the coaxiality of each section of the fuselage. [0003] At present, the domestic aircraft level measurement work adopts the sub-item level measurement method, mainly adopts the level measurement method based o...

Problems solved by technology

[0003] At present, the domestic aircraft level measurement work adopts the sub-item level measurement method, mainly adopts the level measurement method based on optical theodolite, and compares the difference between the measurement points in the direction of the fuselage coordinate axis with the theoretical value on the aircraft level measurement chart to check Whether the installation between the various parts of the aircraft meets the requirements, whether the geometric dimensions of each profile are within the limited range, but the level measurement based on the optical theodolite mainly has the disadvantages of inconvenient disassembly and assembly of the transfer tool, small measurement range and inconvenient use
