Bonding tooling and bonding method suitable for remanufactured honeycomb structural parts of rudder surface

Abstract

The invention relates to a bonding tool suitable for remanufacturing honeycomb structural parts of rudder surfaces. The honeycomb structural part includes a control joint, a suspension joint, a front beam, an upper skin and a lower skin respectively fixedly connected with the control joint and the suspension joint. , trailing edge strip, end rib and honeycomb core, the bonding tooling includes a tooling base, a steering joint positioning tooling that can be connected to the steering joint, a suspension joint positioning tooling that can be connected to the suspension joint, and a beam core module positioning block arranged on the tooling base And the positioning block of the rib core module, the beam core mould connected with the front beam, the rib core mould connected with the end rib, the beam cover slidably connected with the beam core mould and the rib cover slidably connected with the rib core mould. By fixing the positions of the manipulation joint positioning tool and the suspension joint positioning tool, the positions of the old front beam, the old manipulation joint and the old suspension joint are fixed, so as to fix the positions of the rest of the new parts of the remanufactured honeycomb structure, and improve the relationship between the old parts and the glue. Assembly adaptability and bonding quality of connecting tooling.

Description

technical field [0001] The invention relates to the technical field of full-height honeycomb structure gluing of rudder surfaces, in particular to a gluing tooling suitable for remanufacturing honeycomb structural parts of rudder surfaces and a gluing method thereof. Background technique [0002] like figure 1 As shown in the figure, the rudder surface honeycomb structure is generally assembled and connected by a control joint 1, several suspension joints 2 and several honeycomb unit bodies. The typical structure of the honeycomb unit body is a wedge-shaped full-height honeycomb bonding structure, respectively The upper skin 3, the lower skin 4, the front beam 5, the trailing edge strip 6, the end ribs 7 and the honeycomb core 8 are jointly glued together. The existing rudder surface honeycomb structure bonding technology is developed for the development of new parts. The existing technology is based on digital models to design and manufacture bonding tooling, molding and p...

Problems solved by technology

[0004] The rudder surface honeycomb structural parts to be repaired in depth are generally used for a long time, and the skin and honeycomb core 8 are generally severely damaged and corroded. In the process of remanufacturing and repairing, they are generally replaced with new ones, while the control joint 1 is retained. , Suspension joint 2 and front beam 5 and other skeletons connected with the body, if the skeleton is damaged, it will be used after repair, and the rear edge strip 6 and end rib 7 are generally replaced because they are easy to deform during the decomposition process; old parts Due to long-term use, there will inevitably be stress deformation, and some repair areas after damage will further increase the size deviation

[0005] Therefore, for the rudder surface honeycomb structure parts that need to be remanufactured and repaired, there are many transition interfaces between old and new parts when the adhesive components are glued and assembled. , the mismatch between the glued tooling and the old parts significantly increases the risk of debonding and weak bonding. On the other hand, the tooling designed and manufactured based on the digital model does not have the function of restoring the key interface characteristics of the old parts

[0006] Therefore, the inventor provides a kind of gluing frock and its gluing method that is applicable to remanufactured honeycomb structural parts of rudder surface, solves the poor matching adaptability of the old parts of remanufactured honeycomb structural parts and gluing f Difficulty in positioning and difficulty in coordinating new and old parts to ensure the bonding quality of remanufactured honeycomb structural parts
