That is, for example, a honeycomb sandwich panel that is a component attached to a product, such as an aircraft wing flap, and has both outer surfaces bent together, when manufacturing this or after partially replacing the defective part afterwards. The present invention relates to a bonding device used for heating and pressing bonding between a honeycomb core as a core material and a skin plate.

[0002]

2. Description of the Related Art FIG. 4 is a front sectional view showing each example of a conventional bonding apparatus of this kind, and FIG. 5 is a front sectional view showing an example of its use. As shown in these drawings,
Honeycomb sandwich panel with curved outer surfaces 1
Regarding the heating and pressurizing adhesion between the honeycomb core 2 as a core material and both skin plates 3 in the production or partial replacement thereof, the adhering devices 4, 5, 6 shown in FIG. Is used with. In the bonding apparatus 4 shown in FIG. 4 (1), the curved bonding jig 7 is made of a plate, and in the bonding apparatus 5 shown in FIG. 4 (2), the curved bonding jig 7 is used. Is made of honeycomb panel, and in the bonding device 6 shown in FIG. 4 (3), the curved bonding jig 7 and the like are made of cast products. And each bonding device 4, 5, 6
Together, the curved bonding jig 7 is used for the frame 8
It is attached and fixed to a flat rigid plate 9 via the bonding device 6. In the bonding device 6 shown in FIG. 4 (3), for example, the bonding jig 7 and the frame 8 are integrally cast.

Here, a case where the bonding devices 4, 5, 6 provided with such a bonding jig 7 are used for partial replacement, that is, repair of the honeycomb sandwich panel 1 will be described as an example. In the case of honeycomb sandwich panel 1 in which both upper and lower outer surfaces are curved, such as flaps of an aircraft wing, when a so-called delamination portion such as corrosion peeling or adhesive deterioration peeling partially occurs, such a defective portion A is generated. It needs to be repaired. When the defective portion A is generated only in a very small part of the entire honeycomb sandwich panel 1, it is possible to repair it without using any jig, but the diameter of the defective portion A is 200 mm or more. When it reaches, from the aspect of the rigidity maintenance after the honeycomb sandwich panel 1,
Conventionally, repairs have been performed using the bonding devices 4, 5, and 6 equipped with the bonding jig 7. In other words, the defective portion A is removed from the honeycomb sandwich panel 1 and the replacement portion B is used instead.
After inserting the same while interposing an adhesive, a heating and pressurizing device such as an autoclave and an adhering device 4 provided with an adhering jig 7.
It has been conventionally performed that the exchange part B is adhered to the periphery by heating and pressurizing the honeycomb sandwich panels 5 and 6 to partially exchange the honeycomb sandwich panel 1. In such a case, it is conceivable to replace the entire honeycomb sandwich panel 1 in which the defective portion A has occurred, but the cost burden becomes excessive, and such a total replacement has not been performed conventionally.

By the way, such a bonding device 4, 5, 6
When repairing using the bonding jig 7, first, the curvature of the outer surface of the honeycomb sandwich panel 1 to be replaced including the defect portion A is measured by NC or the like. Then, based on this measurement result, a metal material such as an aluminum material or an aluminum alloy material is NC-processed or cast (the honeycomb panel may be bent), so that the outer surface of the honeycomb sandwich panel 1 to be replaced is Adhesive jig 7 and adhesive device 4 consisting of the corresponding curved inner surface shape
5 and 6 were produced and prepared. The honeycomb sandwich panel 1 is typically made of a metal material such as an aluminum material or an aluminum alloy material. In that case, a similar adhesive material such as a metal material such as an aluminum material or an aluminum alloy material or a honeycomb panel is used. Although the tool 7 is manufactured and prepared, when the honeycomb sandwich panel 1 is made of another material, for example, a non-metal material such as a fiber reinforced plastic material, the bonding jig 7 also corresponds to the material due to the expansion coefficient. The one selected is used. Of course, also in this case, according to the case of using a metal material such as the above-mentioned aluminum material, first, the bending of both outer surfaces of the honeycomb sandwich panel 1 including the defect portion A is measured, and based on the measurement result, for example, an autoclave, etc. By applying heat and pressure, the bonding jig 7 with the corresponding curved inner surface is manufactured.
It was prepared.

When repairing the defective portion A, first of all,
After removing the defective portion A from the honeycomb sandwich panel 1 (the defective portion A often occurs, for example, from one skin plate 3 of the honeycomb sandwich panel 1 to a corresponding portion of the honeycomb core 2 as a core material), the defective portion The replacement part B, which replaces A, is inserted into the empty space with the adhesive interposed. Then, the honeycomb sandwich panel 1 having undergone such replacement is sandwiched between the bonding jigs 7 of the upper and lower bonding devices 4, 5, 6 as shown in FIG. The exchange part B was adhered to the surroundings by heating and pressurizing. Partial replacement of the honeycomb sandwich panel 1 was thus carried out.

[0006]

By the way, the following problems have been pointed out in such a conventional example. For example, the bending of the honeycomb sandwich panel 1 used for flaps of aircraft has various shapes.
Moreover, the partial replacement site, that is, the location where the defective portion A is generated is also different in each place, and the actual replacement site cannot be identified until at the time of repair. That is, there are various basic shapes of the curved shape of the outer surface of the honeycomb sandwich panel 1 to be replaced in which partial replacement is performed, and the replacement parts are also various places. Moreover, in the case of an aircraft, the flap is deformed as the flight time becomes longer.
Are various and various, and various modifications thereof are added.

[0007] First, therefore, in the past, the situation is almost similar to the actual product matching, and when a honeycomb sandwich panel 1 of this kind is partially replaced, an adhesive jig having an inner surface shape corresponding to the bending of the outer surface thereof. It is not easy to preliminarily manufacture and prepare the bonding devices 4, 5 and 6 equipped with 7,
Even if all the points can be accurately manufactured and prepared in advance, a great amount of waste (unused items) will occur. Therefore, conventionally, when the honeycomb sandwich panel 1 is partially replaced, the inner surface of the bonding jig 7 of the bonding device 4, 5, 6 does not surely correspond to the outer surface of the honeycomb sandwich panel 1. In many cases, the pressurization is insufficient and the replacement part B is not accurately adhered to the surroundings.
Problems have been pointed out in the accuracy and reliability of the bonding jig 7 of No. 6.

Secondly, the conventional bonding device 4, 5, 6
As described above, the bonding jig 7 of No. 1 measures the bending of the outer surface of the honeycomb sandwich panel 1 including the defective portion A geometrically, and based on the measurement result, NC processing, casting, bending processing, etc. It was manufactured and prepared by heating and pressing with an autoclave. Therefore, the conventional bonding jig 7 and the bonding devices 4, 5, and 6 have been pointed out to have a problem in terms of cost, such as a large amount of cost for manufacturing and preparing.

Thirdly, the bonding jig 7 of the conventional bonding apparatus 4, 5 and 6 is manufactured and prepared by measurement, NC processing, casting, bending, heating and pressing by an autoclave, etc. as described above. It took a long time to manufacture, prepare, and use. On the other hand, the flaps and the like of the aircraft have a very limited repair time in operation (for example, 3 days at maximum), so that the defective portion A of the honeycomb sandwich panel 1 can be partially replaced within a short time. Urgently want to carry out,
There are many requests from the site. Now, there have been many problems in that production and preparation of the bonding jig 7 and the bonding devices 4, 5, 6 used for such replacement often fail in time.

The above-mentioned places relate to an example in which the conventional bonding devices 4, 5 and 6 are used for partially replacing or repairing the defective portion A of the honeycomb sandwich panel 1. Regarding the example in which No. 6 was used for manufacturing the honeycomb sandwich panel 1, the problem similar to the above was pointed out. That is, when the conventional bonding devices 4, 5 and 6 provided with the bonding jig 7 are used for bonding the honeycomb core 2 as the core material and both skin plates 3 at the time of manufacturing the honeycomb sandwich panel 1, According to the above, firstly accuracy and reliability, secondly manufacturing and preparation cost aspects,
Thirdly, problems were pointed out in terms of time.

In view of such circumstances, the present invention has been made to solve the problems of the above-mentioned conventional example. In claim 1, a heating heater section, an air bag for compressed air,
By adopting a rigid plate or the like, in claim 2, a sand bag is adopted in place of the air bag, and in claim 3, a heated compressed air air bag is used in place of the heating heater section and compressed air air bag.
