Embodiment Construction

[0020] A method for installing aircraft components based on laser positioning is provided, comprising the following steps:

[0021] Step 1) Determine the area of ​​the laser projection area, find the component installation position coordinates in the aircraft model, take the component installation position coordinates as the center, and take the laser projection area area as the range, select a plurality of reference coordinate points in the aircraft model, and obtain the described Coordinates of multiple reference coordinate points, obtain the relative positional relationship between all reference coordinate points, obtain the relative positional relationship between at least one reference coordinate point and the component installation position coordinates, and obtain the relationship between all reference coordinate points and the fuselage reference plane relative positional relationship;

[0022] Step 2) mark all reference coordinate points on the aircraft fuselage accordi...

Abstract

The invention belongs to the technical field of aircraft manufacturing, particularly relates to an installing method of an airplane component based on laser positioning, and relates to an airplane system guide pipe support frame installing and detection method. An airplane coordinate system is built by mainly using an airplane entity and a laser tracking instrument; the projection equipment coordinate system building is completed by using measuring points on the entity; then, the guide pipe support frame shape and position under the airplane coordinate system are projected out by using a projection instrument; finally, a guide pipe is installed according to the projection shape and position. The method mainly solves the technical problem that the installing position of an airplane system guide pipe support frame is frequently changed, and cannot be fixed. The method is mainly used for the quality control of the airplane system guide pipe support frame installation.

Description

technical field [0001] The invention belongs to the technical field of aircraft manufacturing, in particular to a method for installing aircraft components based on laser positioning. Background technique [0002] The production of catheters has become one of the important bottlenecks restricting the improvement of aircraft mass production capacity. Traditional aircraft are installed by proofing installation. Due to the need for overall planning and reasonable layout when installing conduits on the aircraft production site. Generally follow the principle of connecting cables to conduits and brackets, and conduits to brackets. Therefore, the accuracy of the position of the conduit bracket has become one of the important factors affecting the preparation of the conduit. At present, due to the backward installation methods of the conduit bracket (marking and positioning installation), the installation accuracy Not high, component assembly errors, and frequent changes in the p...
