Ultrasonic cleaning device and process for flexible production of aerospace structural parts

The invention provides an ultrasonic cleaning device for flexible production of aerospace structural parts and an automatic cleaning process. The device comprises a machine body, a cleaning assembly, an air knife, a manipulator and a lifting table. A workpiece to be cleaned is detachably mounted on the tray; during use, the tray and the workpiece are driven to move through the manipulator, ultrasonic cleaning is performed through the cleaning assembly, and drying is performed through the air knife. By means of the mechanical arm for material transportation on the production line, the cleaning assembly, the air knife and the lifting table are matched, ultrasonic cleaning and automatic overturning drying on the machine tool are successfully achieved, the problem that water drops on the surface of an inner cavity are difficult to remove is solved, and efficient cleaning is completed by combining a single cleaning tank with the auxiliary mechanical arm. 本发明提供一种航天结构件柔性生产的超声波清洗装置及自动化清洗工艺，装置包括机体、清洗组件、气刀、机械手以及升降台；待清洗
