Problems solved by technology

[0003]At present, the forming of carbon panel aluminum honeycomb sandwich panels mainly adopts the vacuum hot pressing curing method. During the process, due to the large difference in expansion coefficient between the upper and lower panels and the positioning tool, the relative displacement between the upper and lower panels and the side embedded parts caused the dimensional accuracy of the honeycomb panel to be unguaranteed, and the bonding quality of the embedded parts was poor. Difficult tooling processing, long production cycle, high cost, etc.

Embodiment 1

[0033] A laminated board side member embedded positioning means comprising a positioning pin, the positioning plate 2, the side block 3 is positioned embedded, embedded-side positioning plate 4, screws 5 and screws 6; lower positioning plate 2 and the side positioning member embedded plate 4 are made of carbon fiber composite material, the side block 3 is positioned embedded aluminum alloy.

[0034] 1 by the positioning pin of the side member embedded positioning block 32 and the lower positioning plate is positioned, preferably, the positioning block 3 and the lower plate is positioned by the positioning pin 1, pin hole 7 and a circular pin hole 8 to waist-shaped side member 2 is positioned embedded . 5 by screws and the embedded side positioning block 32 is fixedly connected to the lower positioning plate, positioned side embedded block embedded member 3 and the side plate 4 is connected by locating screws 6 is positioned. Embedded screw 6 through the side positioning member 4, ...

Embodiment 2

[0040] This embodiment is accomplished on the basis of Example 1, the pore size increases, the parameters for Example 1, to achieve an overall structure of concrete, to more closely match the connection between the various components. specific:

[0041] Screw positioning holes correspond with the threaded hole, preferably, the screw diameter of the positioning hole 6mm, threaded bore diameter 5mm. Wherein the lower positioning plate 2 has a plurality of screw pilot holes, the positioning hole diameter greater than the nominal diameter of the screw. Buried lateral positioning threaded hole of block 3 is greater than the nominal diameter of the screw 5, so that the screw can not embedded into the side block 3 is positioned to enhance the structural stability, to avoid changing the morphology expanded.

[0042] Wherein the circular positioning hole plate 3 side of the positioning member 10 embedded aperture equal to the nominal diameter side member is preferably embedded in, the aper...

Abstract

The invention provides a sandwich plate side embedded part positioning device, and relates to the field of composite material honeycomb plate forming and cementing toolings. The sandwich plate side embedded part positioning device comprises a positioning pin, a lower positioning plate, a side embedded part positioning block, a side embedded part positioning plate, a screw and a positioning screw. The side embedded part positioning block and the lower positioning plate are positioned through the positioning pin, the side embedded part positioning block and the lower positioning plate are fixedly connected through the screw, and the side embedded part positioning block and the side embedded part positioning plate are positioned and connected through the positioning screw. All parts of the device can be separately machined, machining is easy, the period is short, and cost is low; operation is easy, disassembly and assembly are convenient, reset precision is high, and repeated use can be achieved; a side embedded part is reliable in gluing quality, high in positioning precision and stable in size; and the side surface flatness, straightness and verticality with upper and lower panels of a sandwich plate are high.

Description

Technical field [0001] The present invention relates to a composite material formed honeycomb panels glued tooling art, in particular, it relates to a sandwich panel side member embedded positioning means. In particular a - carbon aluminum honeycomb sandwich panel side panel member embedded positioning means. Background technique [0002] Honeycomb panels as an important structural element of modern satellite, the satellite functions as a support, stand-alone mounting, the load transmission action. A typical cellular board panels sandwiched between two layers of a honeycomb core, the embedded member embedded or buried surface between the panels, and the side member embedded compounded with an adhesive, wherein the side member is embedded between the mezzanine board connection or satellite A single unit provides mounting interface. Honeycomb panel due to the carbon plate excellent performance two carbon fiber composite panel, so compared to conventional aluminum honeycomb panel ha...
