Abstract

The invention discloses a novel longitudinal-torsional combined ultrasonic elliptic vibration turning method and device. An amplitude changer is totally T-shaped, the end in the horizontal direction is arranged as a small end, the other end is arranged as a first large end, and the vertical direction is arranged as a second large end; reflecting end sets, piezoelectric ceramic pieces and copper electrodes are arranged at the first large end and the second large end; the total size of the amplitude changer is designed according to a half-wavelength rule; a cutter is arranged in the center of the outer end of an emitting end; the two sets of piezoelectric ceramic pieces are excited by high-frequency electric signals of an ultrasonic generator to generate perpendicular longitudinal vibration;and two rows of waves are overlapped in the intersection to generate longitudinal-torsional combined vibration. The device adopts the integral T-shaped structural design to simplify the connecting structure between a transducer and the amplitude changer, directly overlaps one set of perpendicular vibration to generate the longitudinal-torsional combined vibration, greatly increases the output vibration frequency of the emitting end, and meanwhile, improves the longitudinal-torsional component ratio.

Description

Technical field: [0001] The invention relates to an ultrasonic vibration processing equipment, in particular to a novel longitudinal-torsional combined ultrasonic elliptical vibration turning method and device. Background technique: [0002] Longitudinal-torsional composite ultrasonic machining technology has been widely concerned because of its good processing effect on hard and brittle materials since its birth, and its application range has been continuously expanded. However, common horns are usually designed with separate transducers and horns. The transducers and horns are connected by bolts. The ultrasonic vibration will have a large loss during the transmission process and cannot be transmitted at the transmitting end. to obtain the desired amplitude. Thereby affecting the actual processing effect and hindering the further promotion of ultrasonic processing technology. Invention content: [0003] The technical problem to be solved by the present invention is: to ...
