Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sheet paving, in particular to a sheet paving auxiliary positioning structure and a sheet paving tool. Background Art
[0002] In the field of aircraft design, the use of composite materials has become a new mainstream development trend, which can reduce the weight of the aircraft and improve economic benefits. In the production and manufacturing of composite materials, manual laying is the most widely used molding method, which is flexible, low-investment, fast-return, and can realize the laying molding of various small parts with relatively complex structures.
[0003] When paving aircraft component structures, in order to improve the structural efficiency of the component structure, it is necessary to partially re-pave the curved surface with a larger curvature with material sheets. For example, for the rib structure, the rib structure includes a web and flanges arranged at both ends of the web. The flanges are basically perpendicular to the web plane. After paving the rib structure on the paving tool, it is necessary to re-pave the material sheets at the intersection of the flange and the web to design a reinforcement layer structure to improve the bearing capacity of the flange. At present, laser projectors are mostly used to locate the paving position of the material sheets, project the projection line contour through the laser projector, and then pave the material sheets according to the laser projection line contour. For the rib structure, at least two laser projectors are required to project the two intersections at both ends of the web from both sides of the tooling to form a projection line contour. However, laser projectors are generally suspended above the structure of the components to be laid, and they need to occupy a large production area during laying. It is difficult to produce multiple component structures at the same time, which affects production efficiency and the use of production sites. In addition, each laser projector needs to download the projection program and debug the projection before working, which takes a long time to prepare. Utility Model Content
