Problems solved by technology

[0006] However, in the actual use of the above structure, especially in the manufacturing process of large aircraft, it is often not enough to rely on the conformal frame to support the wing panel, and it is necessary to add auxiliary support devices, but the additional structure not only increases the complexity of the operation, In addition, the auxiliary support device sometimes produces the problem of stress concentration damage and deformation of the wing panel near the support point

Abstract

The invention discloses a shape-preserving and positioning tool for a composite wing wallboard. The tool comprises a shape-preserving frame and an adsorption supporting assembly installed on the shape-preserving frame. The tool is characterized in that an adaptive supporting assembly stretching into a process open hole of the wing wallboard is arranged on the shape-preserving frame. The shape-preserving and positioning tool for the composite wing wallboard is provided with the adaptive supporting assembly, the process open hole of the wing wallboard is used for assisting in supporting the wing wallboard, no additional supporting equipment needs to be additionally arranged for the wing wallboard, and meanwhile stress concentration generated at the supporting position of the wing wallboard is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of aircraft manufacturing, in particular to a shape-conserving positioning tool for composite material wing panels. Background technique [0002] Composite materials have the advantages of high specific strength, high specific modulus, good heat resistance, small thermal expansion coefficient, and good corrosion resistance, so they are very suitable as aircraft manufacturing materials. At present, composite materials have been used in the manufacture of new-generation aircraft and have significantly improved aircraft performance. It is foreseeable that the use of composite materials in aircraft will be more extensive and important. [0003] For a typical composite wing panel, when it is assembled to the wing box, it needs to go through positioning holes, pre-connection, hole making, panel decomposition, cold extrusion strengthening, panel fitting, final hole making, spot facing and final In the process of c...
