Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of aircraft manufacturing, and specifically relates to a composite stiffened curved wall plate supporting device. BACKGROUND
[0002] Modern aircraft fuselage wall plates, as main load-bearing components, have typical characteristics such as large size and complex curvature, and the manufacturing precision thereof directly relates to the structural safety and aerodynamic performance of the aircraft. Although traditional metal wall plates have good mature technology, they are limited by material specific strength and fatigue resistance and are difficult to meet the lightweight and long-life design requirements of new-generation aircraft. With the breakthrough of composite material technology, composite material wall plates have gradually replaced traditional metal wall plates based on the advantages of high specific strength, corrosion resistance and designability.
[0003] The manufacturing process of the composite stiffened curved wall plate involves multi-process cooperation, and different processes have different requirements for the attitude of the component. For example, in the detection process, in order to judge the deformation of the outer surface of the wall plate and the offset of the inner surface of the stringer, the inner / outer surface of the component needs to be detected alternately. When a portable three-dimensional scanner is used for shape detection, the part needs to be placed and detected in two attitudes. The appearance quality inspection of the wall plate usually needs to be performed in the attitude of the outer surface facing upward. The thickness test of the wall plate also needs to maintain the attitude of the outer surface facing upward. Due to the difference of the outer surface of different wall plates, the position and structure of the internal stringer are also different. In the above processes, a special supporting frame is usually customized for each different wall plate. The special supporting frame of each wall plate consumes a large amount of materials, manpower and time, increases the production cost, and has the problems of high cost of customized supporting frame and poor economy. At the same time, the special supporting frame occupies a large amount of space and cannot be flexibly adjusted, which increases the difficulty of storage and management and affects the layout of the production line.

[0020] The present invention can be further described through the following embodiments; however, the scope of the present invention is not limited to the following embodiments. It should be understood that the embodiments described herein are disclosed by way of illustration only, and the present invention is not intended to limit its scope to the details of the construction and arrangement of the components described below or illustrated in the figures. Furthermore, in describing preferred embodiments, specific terminology will be used for clarity. It should be understood that each specific term includes all technical equivalents that operate in a similar manner to achieve a similar purpose.
[0021] Example: Taking the support of a 3m × 2m composite wall panel with hyperbolic curvature as an example, such as... Figures 1 to 3 As shown, the support device mainly consists of two parts: a load-bearing structure and a connecting structure. The load-bearing structure includes three independent support frames 1. The connecting structure uses high-strength aluminum profiles to connect longitudinal beams 2 as the core connecting components. The support frame 1 is assembled from aluminum profiles and includes two crossbeams 11, two longitudinal beams 12, and two long vertical beams 13. The two crossbeams 11 are the upper crossbeam and the lower crossbeam, respectively. The bottom of both ends of the lower crossbeam is equipped with a traveling wheel 106. The two longitudinal beams 12 are connected in the middle of opposite sides by the lower crossbeam. Long vertical beams 13 are provided in the middle of the upper part of the longitudinal beams 12. Horizontal clamps 103 are provided on the upper part of the two long vertical beams 13 respectively. An upper crossbeam is provided between the two long vertical beams 13. A channel steel 104 is provided on the upper crossbeam as a basic bearing unit. A support block 101 is installed in the channel steel 104 as the main body supporting the wall panel, and its upper part protrudes out of the channel steel 104. The bearing profile of the support block 101 is designed according to the profile of the 3m×2m wall panel support part.
