Embodiment approach

[0082] Obtain the resonant current of the ultrasonic component in real time, wherein the resonant current is the current of the ultrasonic component at the resonant frequency;

[0083] Calculate the current absolute value of the current difference between the resonant current and the signal current corresponding to the preset signal;

[0084] When it is determined that the absolute value of the current is greater than the second preset (preset current threshold), the signal current corresponding to the preset signal is adjusted to be equal to the resonant current, so that the frequency of the adjusted signal is the same as the resonant frequency.

[0085] It should be noted that, as can be seen from the above, the signal frequency adjustment of the preset signal can be realized by adjusting the signal frequency or by adjusting the signal current, and those skilled in the art can choose as needed.

[0086] like Figure 4 As shown, acquiring the resonant frequency of the ultras...

Description

technical field [0001] The present application relates to the technical field of ultrasonic processing, and in particular, to an ultrasonic power source and a power supply method thereof. Background technique [0002] With the development of modern machining technology, ultrasonic machining technology is widely used in precision machining, such as diamond, ceramics, glass, cemented carbide, stainless steel, titanium alloy and other fields, and has achieved good processing results. [0003] Ultrasonic tool holders and ultrasonic weldments are the basic components in ultrasonic machining, and their stable work will directly affect the machining efficiency. An ultrasonic power source is a device used to supply ultrasonic energy to an ultrasonic tool holder or ultrasonic weld. To make the ultrasonic tool holder or ultrasonic weldment work properly, the ultrasonic power source must match the working frequency of the ultrasonic tool holder or ultrasonic weldment. However, the ou...
