Abstract

The invention belongs to an airplane assembling technology, relating to an improved method for drilling riveting holes in a body structure of an air plane. The method is characterized by comprising the following drilling steps: manufacturing an elastic ruler; drilling process holes; drilling equidistant holes in the elastic ruler (1); drilling the riveting holes in the body structure of the airplane. According to the method for rapidly drilling the riveting holes of the body structure of the airplane, the labor intensity is greatly lightened, the working efficiency is improved, the interval error of the riveting holes is reduced, and the riveting quality is ensured.

Description

technical field [0001] The invention belongs to the aircraft assembly technology and relates to the improvement of the drilling method for the riveting holes of the aircraft fuselage structure. Background technique [0002] When drilling the riveting holes of the aircraft fuselage structure, since the aircraft fuselage structure has a profile, the riveting holes on the profile are arranged in a straight line when the profile is unfolded into a plane, and the spacing of the riveting holes is equal. The current practice is: determine the positions of all riveting holes on the profile surface by marking 1, and then drill. Its disadvantages are: high labor intensity, low work efficiency, large spacing error of riveting holes, and poor riveting quality. Contents of the invention [0003] The purpose of the invention is: to propose a fast drilling method for riveting holes in aircraft fuselage structures, so as to reduce labor intensity, improve work efficiency, reduce the spac...
