A UAV rotor frame ultrasonic grinding and polishing system and method

Abstract

The invention provides an ultrasonic grinding and polishing system for the UAV rotor frame, which has a clamping device for clamping the UAV rotor frame; the flexible polishing capsule is a sealed capsule, and the inside of the capsule can be filled with liquid. Flexible deformation is generated under the filling of liquid, and it is closely attached to the inner wall of the UAV rotor frame for grinding and polishing; the electroacoustic vibration transducer is connected to the ultrasonic generator and placed inside the flexible polishing capsule, and the vibration rod is amplified Connected to the electroacoustic vibration transducer, the ultrasonic vibration of the electroacoustic vibration transducer is amplified and transmitted to the liquid, and the flexible polishing capsule is driven to perform ultrasonic vibration grinding and polishing. Using ultrasonic vibration technology to precisely control the grinding and polishing, the grinding and polishing device can effectively adapt to the complex structure of the rotor frame, making the polishing precise and fast, and realizing the processing efficiency and surface quality requirements of the UAV rotor frame.
