Aircraft component digitized flexible assembling measuring method based on laser tracking measuring technique

Abstract

Provided is an aircraft component digitized flexible assembling measuring method based on a laser tracking measuring technique. The assembling measuring method comprises the following steps of (1) carrying out preparation work of assembling measurement, (2) carrying out work of the assembling measurement, and (3) carrying out parallel collaborative measurement in real time. The aircraft component digitized flexible assembling measuring method based on the laser tracking measuring technique relates to the combination of an assembling technique and the measuring technique, the theoretical position information of engineering data concentrated product digital analogy is compared with the coordinates, obtained by a laser tracking instrument in real time, of reference points of assembly parts to form positional deviation, the positional deviation is transmitted to a movement control system, the movement control system generates tool pose control instructions by analyzing the positional deviation and transmits the tool pose control instructions to a flexible tool, the flexible tool drives a workpiece to adjust poses together, and through the coordinated operation of the movement control system, the flexible tool and the workpiece, a closed loop control system is formed to complete the assembling work. The aircraft component digitized flexible assembling measuring method based on the laser tracking measuring technique has good practical value and wide application prospect in the laser tracking measuring technique and the aircraft digitalized assembling field.

Description

technical field [0001] The invention is a digital flexible assembly measurement method for aircraft parts based on laser tracking measurement technology, which belongs to the field of laser tracking measurement technology and aircraft digital assembly. Background technique [0002] The design of modern aircraft is developing in the direction of structural integration, large-scale parts, and manufacturing precision. This not only increases the difficulty of parts manufacturing, but also increases the requirements for assembly quality. The development of foreign assembly technology is very rapid. Advanced digital technology is used to realize its precise assembly, and a large number of digital definition models and optical measurement and positioning technology and equipment are used. Domestic aircraft manufacturing and assembly are still relatively weak. These advanced technologies have not been systematically researched and applied, and a complete system has not been formed....
