A rapid manufacturing method and manufacturing auxiliary system for a composite material structural plate

Abstract

The invention discloses a rapid manufacturing method of a composite material structural plate and a manufacturing auxiliary system. With the help of the manufacturing auxiliary system, through the acquisition of the actual image of the skin under the structural plate, the acquisition of the image of the structural plate model, and image matching and transformation, the image of the structural plate model is passed through The projector is projected onto the surface of the lower skin, and then the embedded parts, the honeycomb core and the skin on the structural plate are assembled in sequence. The invention can simplify on-site workers' acquisition of assembly information, and greatly improves production efficiency, accuracy and first-time success rate.

Description

technical field [0001] The invention relates to the technical field of composite material structural panels, in particular to a rapid manufacturing method of composite material structural panels and a manufacturing auxiliary system. Background technique [0002] The composite material structural panel is composed of upper and lower skins, honeycomb core, and embedded parts. The skin is located on the outermost side of the structural panel; Structural slabs inside the honeycomb core for connecting external objects to structural slabs. Composite structural plates have the characteristics of high strength and low density, and are widely used in the field of spacecraft development. [0003] Usually, spacecrafts have different configurations, different layouts, and are developed in one piece, resulting in different structural panels and one-piece production. The skin of the composite structural plate is cut and drilled by machine, but the honeycomb core and embedded parts need ...

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.
