Cementing tool and cementing method suitable for control surface type remanufactured honeycomb structural part

Abstract

The invention relates to a cementing tool suitable for a control surface type remanufactured honeycomb structural part, the honeycomb structural part comprises a control joint, a suspension joint, a front beam, an upper skin, a lower skin, a rear edge strip, an end rib and a honeycomb core, and the front beam, the upper skin, the lower skin, the rear edge strip, the end rib and the honeycomb core are fixedly connected with the control joint and the suspension joint respectively. The cementing tool comprises a tool base, a control joint positioning tool which is arranged on the tool base and can be connected with a control joint, a suspension joint positioning tool connected with the suspension joint, a beam core mold positioning block, a rib core mold positioning block, a beam core mold is connected with the front beam, the rib core mold connected with the end rib, a beam outer cover in sliding connection with the beam core mold, and a rib outer cover in sliding connection with the rib core mold. The positions of an old front beam, an old control joint and an old suspension joint are fixed by fixing the positions of the control joint positioning tool and the suspension joint positioning tool, so that the positions of other newly-manufactured parts of the remanufactured honeycomb structural part are fixed, and the assembly adaptability and the cementing quality of the old parts and the cementing tool are improved.

Description

technical field [0001] The invention relates to the technical field of full-height honeycomb structure bonding of rudder surfaces, in particular to a bonding tool and a bonding method suitable for remanufacturing honeycomb structural parts of rudder surfaces. Background technique [0002] Such as figure 1 As shown, the rudder surface honeycomb structural parts are generally assembled and connected by one 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 bonded structure, respectively composed The upper skin 3, the lower skin 4, the front beam 5, the rear edge strip 6, the end rib 7 and the honeycomb core 8 are glued together. The existing rudder surface honeycomb structure bonding technology is developed for the development of new parts. The existing technology is based on the digital model to design and manufacture the bonding tooling, forming and processi...

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
