Abstract
A device and a method for switchable vibration modal ultrasonic are provided. The device includes a hollow shaft, an ultrasonic motor, a limit shell, an electromagnet, a moving tool head, a vibration source and a tool head. The structure design of the ultrasonic motor, the magnetostrictive materials and the drive coil combination of different functions are configured so that, without changing the condition of components, the ultrasonic can switch mode, namely the longitudinal vibration, torsional vibration, and longitudinal and torsional vibration in three different vibration modes. During the operation of the device, different vibration modes are excited without changing the parts, which meets the machining requirements of different vibration forms. Meanwhile, the operation is more convenient and faster, and the overall design structure of the device ensures the efficient and safe operation of the device.
