Technical Field

The invention relates to the technical field of aluminum honeycomb structure gluing, in particular to a method and a tool for verifying the forming quality of a gluing surface of a hyperboloid variable-thickness aluminum honeycomb.

Background

As shown in fig. 1, the aluminum honeycomb is a hyperboloid variable-thickness part, and is generally obtained by selecting an aluminum honeycomb blank to perform double-sided numerical control processing; during processing, firstly fixing the aluminum honeycomb on the auxiliary platform to process a surface B, then overturning the part, installing and fixing the surface B on a tool, and finally processing a surface A; because the aluminum honeycomb blank to be processed is made of a flexible material, the aluminum honeycomb blank cannot be stably clamped like a rigid material during numerical control processing, and clamping modes such as adsorption and sticking are usually adopted or clamping is carried out according to the rigid material after filling media are densified; for flexible materials, the deviation of the numerical control processing surface of the flexible materials is inevitably larger than that of rigid materials such as metals, particularly parts needing to be processed on the surface A and the surface B, the deviation of the surface is increased by secondary clamping, and on the other hand, the aluminum honeycomb is used as a core material of an aluminum skin sandwich structure to participate in gluing, and the process has higher requirements on the precision of the surface of the aluminum honeycomb, so that the deviation of the processing surface of the aluminum honeycomb needs to be detected before gluing to be used as the basis for subsequent repair and assembly in order to ensure the gluing quality; for the large-thickness large-cell low-density double-bending-thickness aluminum honeycomb with the thickness of 220mm, the side length of the cell of 5mm and the density of 31Kg/m3, when the deviation detection is carried out by adopting a conventional verification method, the problem that parts are damaged due to instability and slippage of a honeycomb core cannot be avoided, so that the A surface and the B surface processing deviation are subjected to discrete measurement by using a profile detection clamping plate distributed on a honeycomb processing die for the size detection of the aluminum honeycomb.

For a honeycomb structure manufactured by adopting a vacuum bag-autoclave process, the machining shape surface deviation of the surface A and the surface B in an aluminum honeycomb can be obtained at the same time by a checking method, and the method comprises the following specific steps: laying a layer of glue film of a checking film simulation gluing process on gluing surfaces (A surface and B surface) of the aluminum honeycomb, and extruding the checking film by an upper skin and a lower skin under the support of the aluminum honeycomb after heating and pressurizing; because the matching condition of the adhesive joint surface influences the extrusion force of the adhesive assembly on the checking film, extrusion traces with different depths can be left on the checking film during checking; in the gluing assembly process, the matching condition of the gluing surface is judged according to the trace of the check film, and corresponding compensation measures are made to ensure the gluing quality. When the conventional aluminum honeycomb (single-curve or wedge-shaped section, the thickness of which is not more than 150mm, the side length of a cell is 2-4 mm, and the density of which is 50Kg/m 3-80 Kg/m3) is tested by adopting the existing verification method, the aluminum honeycomb has enough anti-instability capability, when the autoclave is heated and pressurized, the stable support can be provided for the upper skin and the lower skin, the unstable slippage can not be generated, in the limit, the aluminum honeycomb is a large-cell low-density double-curved-thickness aluminum honeycomb with the side length of 5mm cells and the density of 31Kg/m3, when the thickness of the aluminum honeycomb is up to 220mm, the anti-instability capability is reduced sharply, the aluminum honeycomb does not have enough supporting stability when heated and pressurized in the checking process, the honeycomb wall is easy to be unstable under the action of external fluctuation, after the honeycomb is unstable, the upper skin forms a concentrated load on the aluminum honeycomb, causing slippage of the aluminum honeycomb and damage to the upper skin.

For the processing deviation detection of the large-thickness large-hole-grid low-density dual-bending thickness aluminum honeycomb, a conventional checking film checking method cannot be adopted, and a clamping plate detection is often adopted; during the cardboard detects, resume aluminium honeycomb on honeycomb processing mould, adopt the clearance gauge method to A face and B face processing deviation with the help of the several profile detection cardboards of laying on it, this measuring method's limitation lies in can not really reflect the cooperation condition of skin, lower skin and aluminium honeycomb completely like check-up membrane check-up, probably cause follow-up undercompensation or overcompensation, and the data is the discrete data discontinuity, and partial deviation that exceeds standard probably does not obtain, easily causes the compensation to miss, finally leads to the debonding defect when the honeycomb structure splices.

Therefore, the inventor provides a method for verifying the forming quality of the glued joint surface of the aluminum honeycomb with the double curved surface and a verification tool thereof.
