The ultrasonic transducer and amplitude modulator combined piece can improve the accuracy and reliability of ultrasonic vibration processing and solve the problems of the clamping rigidity difference between the conventional ultrasonic transducer and amplitude modulator, difficulty in node finding and large energy consumption in a transmission process and is greatly improved in dust prevention, clamping, precision and energy transmission efficiency.

Description

technical field [0001] The invention relates to a device in the technical field of ultrasonic processing, in particular to an integrated ultrasonic transducer amplitude modulator. Background technique [0002] The ultrasonic vibration system mainly includes a generator, an ultrasonic transducer, a horn, and a workpiece. Its function is to convert the high-frequency electrical signal output by the ultrasonic generator into mechanical vibration energy, and to make the end face of the tool vibrate with a small amplitude through the horn. High frequency vibration for ultrasonic processing. The function of the ultrasonic transducer is to convert high-frequency electrical oscillations into mechanical vibrations. Ultrasonic transducers and amplitude modulators are important components of ultrasonic processing. Making them into one piece can facilitate clamping and positioning, make the vibration direction more stable, and reduce energy loss during transmission. [0003] Ultrasoni...
