[0002] At present, the assembly of complex aircraft products mainly relies on traditional manual assembly methods, combined with some targeted control measures, which can improve the assembly quality of aircraft products to a certain extent, but there is still a considerable gap between the continuous improvement of aircraft product assembly quality technical indicators, mainly reflected In: Assembly accuracy of large-sized parts is not easy to guarantee

Since the maximum size of the parts is over 4m, the parts themselves deform greatly during the manufacturing and assembly process, and the assembly process lacks effective detection and control measures, which cannot meet the technical requirements of the design; composite material / titanium alloy, composite material / aluminum alloy laminate Structural holes are difficult to make. Manual holes require extremely high operating skills for workers, and the efficiency of hole making is low. It is prone to layering of composite materials, elliptical diameters, and unevenness of the head of the connector due to inclined hole positions and inaccurate nesting depths. If the quantity is out of tolerance, it will seriously affect the performance of aircraft products

[0003] The current situation of complex aircraft product assembly shows that traditional manual assembly technology can no longer meet the assembly quality requirements of advanced aircraft products, and it is necessary to fundamentally change the assembly technology means, and digital assembly has become an inevitable choice

The key part of automatic hole-making digital assembly, the closed assembly positioning device is used for the assembly of the front part of the existing aircraft products, but due to the space interference problem, the automatic hole making of the CNC machine tool cannot be realized. Therefore, the existing closed assembly positioning device must be modified The layout method makes it meet the operating space required for automatic hole making
