Flexible tool for detecting and machining aircraft wing panel profile and detecting and machining method

Abstract

The invention relates to the technical field of aircraft manufacture and assembly, and provides a flexible tool for detecting and machining an aircraft wing panel profile. The flexible tool comprises a base platform, a control unit, a longitudinal positioning device, a longitudinal sliding guide rail, a vertical force application device, a horizontal positioning device and a vertical supporting device, wherein the vertical force application device, the horizontal positioning device and the vertical supporting device are controlled by the control unit to detect and machine the aircraft wing composite integral panel profile. The invention further provides a method for detecting and machining the aircraft wing composite integral panel profile by the aid of the flexible tool. By the flexible positioning method and the flexible tool, key feature points of various different large composite integral panels are spatially positioned, panel quality inspection cycle is shortened, cost is saved, production efficiency and quality are improved, and profile detection is high in accuracy and automation by means of modeling and tool matching.

Description

technical field [0001] The invention relates to the technical field of aircraft manufacturing and assembly, in particular to a flexible tooling and a detection and processing method for detection and processing of the shape and surface of an aircraft wing wall plate. Background technique [0002] The manufacture of composite panels for aircraft wings is an important part of the overall manufacturing of large aircraft. Due to the large size of the composite wall panels of aircraft wings, the length can often reach 10-20m or even longer, and the width is 3-5m. Forming difficulties and other characteristics make it prone to manufacturing errors in the manufacturing process. The consequences of these errors have three manifestations: the first is that the shape directly meets the technical requirements, and can be directly machined such as trimming; the second is that a certain force is allowed to be applied to cause deformation. The requirements can also be considered to meet...

Problems solved by technology

Due to the large size of the composite wall panels of aircraft wings, the length can often reach 10-20m or even longer, and the width is 3-5m. Forming difficulties and other characteristics make it prone to manufacturing errors in the manufacturing process

The consequences of these errors have three manifestations: the first is that the shape directly meets the technical requirements, and can be directly processed by trimming and other mechanical processing; the second is that a certain force is allowed to be applied to cause deformation. The requirements can also be considered to meet the technical requirements; the third is that even by applying a certain force, the integral wall panel of the wing composite material cannot meet the requirements, and the assembly process cannot be carried out

[0003] At present, traditional tooling and fixtures cannot well complete the inspection and processing of various complex-shaped and large-scale aircraft wing composite wall panels, and cannot better meet the low-cost, high-cost requirements of the modern aircraft manufacturing industry. Quality, fast response requirements
