Problems solved by technology
If the force is uneven, the height does not increase the limit, etc., it will cause uneven filling of foam rubber and excessive size, resulting in internal defects of parts
When the number of honeycombs is large and the size of the honeycombs is large, it is difficult to ensure the range, size and bonding quality of the cured styrofoam during splicing, and it is easy to cause the slippage of the honeycombs, which affects the stability of the honeycomb forming

Embodiment Construction
[0033] The present invention will further explain and illustrate the present invention in conjunction with the accompanying drawings and specific embodiments. The embodiments and the accompanying drawings are only to further illustrate the technical solutions of the present invention, and cannot be interpreted as limiting the protection scope of the invention.
[0034] The invention utilizes a set of "comb" type fixtures as auxiliary tools to complete the splicing process of foam glue solidification of honeycomb parts. The size of the "comb" fixture depends on the thickness of the honeycomb part and the size of the cells of the honeycomb part. Specific steps are as follows:
[0035] 1. Honeycomb cleaning
[0036] Use a clean cotton cloth dipped in ketone, ethyl ketone, or acetone to wipe the glued surface of the honeycomb core to remove pollutants, impurities, dust or processing debris on the glued surface of the honeycomb core.
[0038] The cle...

The invention belongs to the manufacturing of composite materials, and provides a method for performing honeycomb splicing by utilizing a comb-shaped clamping apparatus. The method is realized on the basis of the comb-shaped clamping apparatus, the comb-shaped clamping apparatus consists of two single-side comb-shaped clamping apparatus and a flexible baffle plate disposed in the middle, a plurality of comb-shaped sawteeth which are uniformly distributed are arranged below the single-side comb-shaped clamping apparatus, and the comb-shaped sawteeth can be clamped in a honeycomb grid to be spliced. In the splicing method, an acting force is directly applied to polyester foam by virtue of the comb-shaped clamping apparatus, the height limitation to the polyester foam is reinforced by effectively utilizing the flexible baffle plate, not only is the foaming size of the polyester foam ensured, but also the foaming range of the polyester foam is strictly controlled, and the unsteadiness of the appearance of the honeycomb can be avoided.
Description
technical field [0001] The invention belongs to the field of composite material manufacturing, and relates to a method for honeycomb splicing by using a "comb" type fixture. Background technique [0002] The honeycomb sandwich structure has the advantages of light weight, high strength, good bending resistance, etc., and has excellent mechanical properties, electrical properties, and heat insulation properties. It is widely used in the aviation field as a structural material or functional material. In the current composite materials Parts account for a large proportion. [0003] Due to the needs of the part structure, it is usually necessary to splice the honeycomb. The currently commonly used honeycomb splicing process is: (1) filling the area where the edge of the honeycomb needs to be spliced with foam glue, (2) filling the foam glue along the direction of the honeycomb on both sides Direction of force, (3) use hard objects to squeeze and position on both sides of the ...
