Title:
NOVEL THREE-DIMENSIONAL ULTRASONIC ELLIPTICAL VIBRATION CUTTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/097803
Kind Code:
A1
Abstract:
The present invention provides a novel three-dimensional ultrasonic elliptical vibration cutting device, consisting of a two-dimensional ultrasonic vibration transducer, an asymmetric ultrasonic horn, and a cutter. The cutter is installed at the output end of the asymmetric ultrasonic horn; the two-dimensional ultrasonic vibration transducer is used for outputting ultrasonic longitudinal-flexural complex vibration; the asymmetric ultrasonic horn is used for converting and decomposing longitudinal vibration outputted by the two-dimensional ultrasonic vibration transducer into second-phase flexural vibration and longitudinal vibration, and outputting a three-dimensional ultrasonic elliptical vibration trajectory on the cutter in combination with first-phase flexural vibration outputted by the two-dimensional ultrasonic vibration transducer. A three-dimensional ultrasonic elliptical vibration trajectory is outputted in a double-excitation mode, the problems of a poor effect of coupling between vibrations, large device geometric dimensions, and high requirements for a three-channel ultrasonic power supply of a conventional three-dimensional ultrasonic elliptical vibration cutting device are solved, and the outputted three-dimensional ultrasonic elliptical vibration trajectory is adjusted according to different cutting applications and machining requirements, so that the device has higher adaptability.
