Ultrasonic device and method capable of switching vibration modes

Abstract

The invention discloses an ultrasonic device and method capable of switching vibration modes. The device comprises a hollow shaft, an ultrasonic motor, a limiting shell, an electromagnet, a moving head, a vibration source and a tool head, and is formed through the structural design of the ultrasonic motor and a magnetostrictive material and the combination of drive coils with different functions,and therefore the device can generate ultrasonic waves with switchable modes, namely three different vibration modes of longitudinal vibration, torsional vibration and longitudinal-torsional vibration, under the condition that components are not replaced. In the operation process of the device, different vibration modes are excited under the condition that the components do not need to be replaced, the machining requirements of different vibration modes are met, meanwhile, operation is more convenient and faster, and efficient and safe operation of the device is guaranteed through the overalldesign structure of the device.

Description

technical field [0001] The invention relates to the field of ultrasonic technology, in particular to an ultrasonic device and method capable of switching vibration modes. Background technique [0002] At present, the ultrasonic vibration device mostly adopts a single vibration mode, which cannot complete the motion control of the tool head. With the rapid development of the manufacturing industry and the increasingly complex processing technology required, it is urgent to invent an ultrasonic method that can switch vibration modes and device. [0003] The invention patent with the publication number CN 104502443A provides a circular array magnetostrictive sensor based on an orthogonal surrounding coil, which can only generate ultrasonic waves in the form of fixed vibration, that is, torsional vibration, which cannot meet the requirements of switching without replacing components. The requirements of multiple vibration states make it impossible to control the motion of the t...
