FLEXIBLE AUTOMATIC GRINDING DEVICE AND GRINDING METHOD FOR AIRCRAFT REPAIRING COMPOSITE MATERIAL

An apparatus for grinding automatically and flexibly a composite material for aircraft repair, and a method for applying the same, which relate to the technical field of grinding composite materials. The apparatus includes a movable platform, a collaborative robot, a floating force-sensitive grinding head mechanism, a dust collector, and a control component. The collaborative robot includes a six-axis mechanical arm, a six-axis force sensor, a robot controller, and a teach pendant. The floating force-sensitive grinding head mechanism includes a floating constant-force apparatus, a pneumatic spindle, an interface for mounting a cutter and automatically switching cutters, and a cutter holder with a grinding wheel and a sandpaper. The dust collector includes a dust-collecting host, and a dust-collecting hood mounted at an end of the six-axis mechanical arm. The dust-collecting hood is of an elastic cone structure made of a transparent plastic film. Unidirectional holes for guiding air into the dust-collecting hood are uniformly distributed on an outer surface of the dust-collecting hood. A rubber strip is mounted at an edge of the dust-collecting hood. Operation processes involved in repairing composite materials, such as grinding, removal, and polishing, are automated or semi-automated. Manual workload is lessened, health hazards of the personnel are reduced, and a quality of repair is improved.
