Abstract

The invention provides an indoor-GPS-based (indoor global positioning system-based) stress-free assembly system for large-size airplane parts, and application thereof. A digital measurement and inspection system, a numerical control execution system and a three-dimensional stress detection system are all connected with an automatic control system for data information transmission. The digital measurement and inspection system comprises an indoor GPS and a laser tracker. Indoor GPS receivers and laser tracker target balls are disposed on parts of an airplane. The numerical control execution system comprises at least three groups of eleven positioners, and a group of three positioners, a group of four positioners and a group of four positioners are used for supporting a front body, a middle body and a rear body. The three-dimensional stress detection system is located on the positioners. The indoor-GPS-based stress-free assembly system has the advantages that the airplane parts are quickly and accurately connected with the positioners, assembly stress is controllable, and airplane assembly efficiency and quality are improved.

Description

technical field [0001] The invention relates to an indoor GPS-based stress-free assembly system for large aircraft components and a method for using the same, belonging to the technical fields of aviation manufacturing engineering and aircraft assembly. Background technique [0002] Modern aircraft have the characteristics of long life, stealth, high reliability, low cost and rapid development, which puts forward higher requirements for aircraft manufacturing process and assembly tooling. Traditional assembly tooling and fixtures can no longer meet the requirements. The development of digital flexible tooling is potential It must be done. Foreign aviation manufacturing companies represented by Boeing and Airbus are vigorously developing digital flexible assembly technology, and generally adopt digital flexible assembly tooling. A large number of versatile digital tooling can be used repeatedly, which can not only shorten the production cycle, simplify the assembly process, ...
