Abstract

The invention provides an ultrasonic driver and a method to be used for driving an ultrasonic tool. The ultrasonic driver comprises a switch module, a sensing element and a control element. The sensing element is used for sensing the voltage and the current of the ultrasonic tool and generating a sensing signal according to the voltage and the current. The control element receives the sensing signal and outputs a control signal. The switch module outputs an ultrasonic signal according to the control signal so as to control the ultrasonic tool to vibrate. When the ultrasonic driver executes the frequency sweeping function, the control element obtains the frequency domain impedance characteristic and the resonance reference point of the ultrasonic tool according to the voltage and the current of the ultrasonic tool under different operation frequencies, and the operation interval and the operation frequency of the ultrasonic signal are decided. When the ultrasonic driver executes the frequency modulation following function, the control element adjusts the operation frequency according to the sensing signal, so that the impedance of the ultrasonic tool is kept consistent.

Description

technical field [0001] The present disclosure relates to an ultrasonic driver and a method, in particular to an ultrasonic driver and a method for driving an ultrasonic tool. Background technique [0002] In today's processing technology, in order to speed up processing and reduce the loss of processing tools, ultrasonic processing is introduced. Ultrasonic machining not only rotates the tool, but also makes the tool vibrate at high frequency in the direction perpendicular to the processing surface. Vibration exerts hammering and abrasive effects on the workpiece, which can cause cracks or crush the processing surface into fine particles. , so that the material on the processing surface can be removed more easily, thereby improving tool life and processing speed. However, as ultrasonic tools and cutting tools continue to perform processing operations, the frequency-domain impedance characteristics of ultrasonic tools will be changed due to the influence of temperature, pres...
