Description

Device and method for repairing damage of airplane Technical Field The invention relates to the technical field of aircraft overhaul, in particular to an aircraft damage repairing device and an aircraft damage repairing method. Background With the continuous increase of aviation traffic, various damages such as skin scratches, cracks, pits and the like can be inevitably generated in the running process of the aircraft, and the damaged wallboard is generally replaced by cutting and repairing-riveting or integrally replacing in the traditional maintenance mode. But traditional maintenance mode, not only cycle is long, with high costs, still probably influence fuel efficiency because of the structure is increased weight, at present, the local spraying repair technique based on polymer composite is rising gradually, and maintainer polishes, cleans the damage position earlier, later evenly sprays repair material to the damage area through arm or handheld spray gun, again at marginal region coating structure glue and heating solidification to realize quick, lightweight restoration. At present, a local spraying repair technology based on a polymer composite material is generally used for directly clamping an aircraft wallboard by adopting a rigid three-jaw or four-jaw chuck to finish positioning, because the aircraft wallboard has a complex double-curvature appearance, the clamping jaw is in hard contact with the wallboard, in the clamping process, if the position of the aircraft wallboard needs to be adjusted, the wallboard is easy to damage, an edge gluing link requires that a glue layer and the contour of the wallboard follow up, but the existing fixture lacks dynamic contour tracking capability, after the clamping jaw is fixed, a glue gun can only move along an approximately straight-line track, and the position of the glue gun cannot be adjusted in real time according to the curvature of the wallboard. Disclosure of Invention In order to solve the technical problems that the clamping jaw is in hard contact with the wallboard and damage is easily caused to the wallboard in the prior art based on the local spraying repair technology of the polymer composite material in the background technology, the invention provides a damage repair device and a repair method for an aircraft.
