Testing method of integral panel parts with double curvatures

Abstract

The invention relates to a testing method of integral panel parts with double curvatures; the testing method comprises the following steps of: (1) drawing a plurality of parallel lines which are vertical to the axes of the panel parts according to the positions of main force bearing structures of the panel parts and formulating positions put forward by manufactures; (2) collecting a data set of curvatures of each parallel line; (3) manufacturing a group of testing clamping plates, wherein bottom surfaces of the testing clamping plates are on the same horizontal surface, the testing clamping plates are vertical to the horizontal surface, and a curved surface which is consistent with the curvature of the corresponding parallel line is arranged on the upper end surface of each testing clamping plate; (4) fixing the testing clamping plates on the horizontal surface, ensuring gaps to be consistent with the positions of the corresponding parallel lines; (5) placing the integral panel parts with the double curvatures on the group of testing clamping plates, wherein the parallel lines are coincided with the corresponding testing clamping plates; and carrying out the curvature measurement on the parts by using a plug gauge. The testing method is used for testing the double curvature appearance surface of the parts by adopting the testing clamping plates and has the advantages of not only reducing the time required for production, but also increasing the accuracy of testing, being convenient for testing and saving time and labor.

Description

technical field [0001] The invention relates to a method for inspecting double-curvature integral wallboard parts, which is used for inspecting the forming of double-curvature integral wallboard parts. Background technique [0002] With the continuous improvement of the performance of modern aircraft, integral structural parts have become the main load-bearing workpieces widely used. The overall structure can reduce the number of parts and connectors, simplify the coordination relationship, reduce the assembly workload, and the assembly deformation is small, which greatly reduces the cost. Among them, the integral high-rib double-curvature wallboard parts are widely used in aviation, aerospace and other fields due to their smooth surface, high strength-to-weight ratio, and good airtightness, especially in aircraft outer wings, central wings, Among the important parts with aerodynamic shape such as vertical tail. At present, the common processing process of such parts is to...
