In order to solve the problem of low accuracy of the fuselage of large aircraft in China

this paper studies　the docking method on the fuselage of a large aircraft. First of all

this paper selects and designs the docking datum of the fuselage and the docking station of the fuselage. Later

in the process of the fuselage docking

using a laser collimator

make the laser collimator light polymerization through artificial adjustment

and the desired data displayed on the digital display table

so as to adjust the body of the aeroplane. Again measuring actual coordinates of fuselage assembly datum using laser tracker

online measurement control system trims fuselage according to the actual coordinates measurement data to meet the requirements of the position of the fuselage and docking. Finally

according to the fine-tuning of the fuselage

the actual sitting value of the measured reference point and the square root of the sum of distance squares of the theoretical coordinates are used to determine whether the fuselage butt meets the standard. The method of fuselage docking in this paper can reasonably control the deviation at the tolerance range. Through the study of large aircraft fuselage docking technology

laser tracker

laser collimator

online measurement software and servo drive device as the main body of online measurement control system

can greatly improve the accuracy of large aircraft fuselage docking.
