Fixed positioning device for rear parts of aircraft products

Abstract

The invention relates to a fixed positioning device of a rear section part of an aircraft product. The fixed positioning device comprises a first fixed positioning device and a second fixed positioning device; the first fixed positioning device comprises a comb-shaped positioning support and a plurality of positioners, wherein the plurality of positioners are arranged on the comb-shaped positioning support; the second fixed positioning device comprises a comb-shaped positioning support and a plurality of positioners, wherein the plurality of positioners are arranged on the comb-shaped positioning support; the first fixed positioning device and the second fixed positioning device are arranged oppositely and accordingly the rear section part of the aircraft product and to be positioned can be positioned.

Description

technical field [0001] The invention relates to an automatic manufacturing equipment, in particular to a fixed positioning device for the rear part of an aircraft product. Background technique [0002] At present, the assembly of aircraft mainly relies on traditional manual assembly methods, combined with some targeted control measures, which can improve the quality of aircraft assembly to a certain extent, but there is still a considerable gap from the demanding assembly quality technical indicators of advanced aircraft, mainly reflected in: large size The assembly accuracy of the frame-beam frame is not easy to guarantee. Since the maximum size of the frame parts is more than 4 meters, the deformation of the parts during the manufacturing and assembly process is relatively large, 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 ...

[0002] At present, the assembly of aircraft mainly relies on traditional manual assembly methods, combined with some targeted control measures, which can improve the quality of aircraft assembly to a certain extent, but there is still a considerable gap from the demanding assembly quality technical indicators of advanced aircraft, mainly reflected in: large size It is not easy to guarantee the assembly accuracy of the frame beam frame

Since the maximum size of the frame parts is more than 4 meters, the deformation of the parts during the manufacturing and assembly process is relatively large, 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 It is very difficult to make holes in the laminated structure. Manual hole making requires extremely high operating skills of workers, and the hole making efficiency is low. It is prone to layering of composite materials, elliptical diameters, and connector heads caused by inclined hole positions and inaccurate nesting depths. The unevenness of the surface is out of tolerance, seriously affecting the performance of the aircraft

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

The key part of automatic hole-making digital assembly, the assembly of the rear parts of the existing aircraft products adopts closed tooling, but due to the problem of space interference, the automatic hole-making with CNC machine tools cannot be realized. Therefore, the layout of the existing closed tooling must be modified , to meet the operating space required for automatic hole making
