Rapid manufacturing method and manufacturing assisting system of composite structural slab

Abstract

The invention discloses a rapid manufacturing method and a manufacturing assisting system of a composite structural slab. By the aid of the manufacturing assisting system, a structural slab model image is projected to the surface of a lower skin object by a projector through acquisition of a lower skin object image of the structural slab, acquisition of the structural slab model image and image matching and transformation, and then, an object embedded part, a honeycomb core and an upper skin of the structural slab are sequentially assembled. With the adoption of the rapid manufacturing methodand the manufacturing assisting system, acquisition of assembly information by workers on site can be simplified, and the production efficiency, accuracy and one-time success rate are greatly improved.

Description

Technical field [0001] The invention relates to the technical field of composite material structural panels, in particular to a rapid manufacturing method and manufacturing auxiliary system for composite material structural panels. Background technique [0002] The composite structural board is made of upper and lower skins, honeycomb cores, and embedded parts glued together. The skin is located on the outermost surface of the structural board; the honeycomb core is located between the two skins and the upper and lower skins are connected by a glue layer; the embedded parts are embedded in In the honeycomb core of the structural panel, it is used to connect the external object with the structural panel. Composite structural panels have the characteristics of high strength and low density, and are widely used in the field of spacecraft development. [0003] Under normal circumstances, spacecraft have different configurations, different layouts, and single-piece development, resulti...

Problems solved by technology

There are many deficiencies in the current production mode, and it is increasingly unable to meet the requirements of efficiency and progress; in order to meet the production expansion needs of structural panels, the development mode of structural panels must be optimized

After upgrading the 2D drawing of the structural plate to the 3D model, the process preparation efficiency has more than doubled; however, there is a problem of insufficient means in the placement of structural embedded parts based on the 3D model: due to the irreducible distance between the computer and the workbench , after the on-site workers use the computer to view the 3D model of the structural slab, such as figure 1 As shown, workers need to manually record or mentally record the type and position of the structural embedded parts, and place the embedded parts according to the records or memories; in addition, due to the distance between the computer and the workbench, workers need to be between the computer and the workbench. Walk back and forth between the stations, repeatedly confirm the model information and physical objects, and ensure that the embedded parts are placed correctly, the thermal control measures are in the correct area, and the position is correct

In this production mode, there have been problems such as high labor intensity of on-site workers, low production efficiency, low first-time success rate of products, and difficult product inspection.
