Embodiment

[0041] A method of processing honeycomb core parts without tape bonding, such as Figure 1-Figure 4 As shown, its specific implementation process includes the following steps:

[0042] According to the clamping position of the honeycomb core part blank 1 on the vacuum platform 2 of the ultrasonic machine tool in a free state, the vacuum device is started after covering the surface of the part blank 1 with a layer of polyethylene film 3, so that the part processing area 5 of the part blank 1 and the remaining material The regions 6 and the vacuum platform 2 form a closed cavity to realize the stable holding of the honeycomb core parts.

[0043] The vacuum adsorption force formed by the vacuum holding method is , is the vacuum pressure of the ultrasonic machine tool, Be polyethylene film 3 vacuum adsorption areas; According to the vacuum pressure parameter of existing ultrasonic machine tool, the thickness of the honeycomb core parts processed in the present embodiment T ...

Abstract

The invention relates to the technical field of honeycomb core part fixing and machining, in particular to a honeycomb core part machining method without adhesive tape bonding, which comprises the following steps: step 1, covering the surface of a honeycomb core part blank with a film, starting a vacuum device, and forming a closed cavity by a part machining area and an excess material area of the part blank and a vacuum platform; secondly, part contour edge cutting is conducted on the blank, and allowance is reserved in the thickness direction; thirdly, profile milling is conducted on the part contour edge of the blank; and fourthly, the part contour edge of the blank is cut off, and part machining is completed. Adhesive tape does not need to be used for bonding, the effect that the part does not deform and does not fall off can be achieved by fixing the honeycomb core part blank in the mode that the film is adsorbed in a vacuum mode, and the fixing effect is good.

Description

technical field [0001] The invention relates to the technical field of holding and processing honeycomb core parts, in particular to a method for processing honeycomb core parts without tape bonding. Background technique [0002] The honeycomb core composite material is different from traditional metal materials. Its core is a hexagonal cell structure with extremely thin wall thickness of only 0.03-0.05mm. It is characterized by high impact resistance and is widely used as a filler in aircraft wings. [0003] When processing the honeycomb core blank material into finished parts, it is necessary to clamp and fix the core grid edge on the bottom surface and the tooling plane. The current honeycomb fixing scheme mainly adopts tape bonding, but the use of tape bonding has the following defects: [0004] ①Double-sided adhesive / single-sided adhesive can only achieve line contact and fixation when pasting blank lines when pasting, the contact and pasting surface is extremely smal...
