Ultrasonic transducer system |
| abstract |
A transducer stack ( 10 ) includes rings ( 16 ) of piezo-electric ceramic alternating with metal electrodes ( 18 ) along a threaded central shaft ( 32 ) extending from a titanium back plate ( 20 ). A spacer or threaded element ( 14 ) threaded on to the shaft ( 32 ) holds the ceramic rings ( 16 ) and electrodes ( 18 ) in compression against the back plate ( 20 ). The transducer stack ( 10 ) is mountable eccentrically to a horn ( 12 ) of an ultrasonically-vibratable tool, away from an axis of an elongate waveguide ( 56 ) extending from the horn ( 12 ). The transducer stack ( 10 ) may vibrate in a flexural mode perpendicular to the waveguide ( 56 ), generating torsional mode ultrasonic vibrations in the horn ( 12 ) and waveguide ( 56 ), or in a flexural mode parallel to the waveguide ( 56 ), generating longitudinal mode ultrasonic vibrations in the horn ( 12 ) and waveguide ( 56 ). The transducer stack ( 10 ) may be tuned by adjusting the length, mass and/or position along the shaft ( 32 ) of the threaded element ( 14 ), the back plate ( 20 ) and/or a second threaded element ( 410 ) mounted to the back plate ( 20 ). Motion sensors ( 22, 24 ) may be mounted to the horn ( 12 ). Torsional vibrational modes of the horn ( 12 ) and waveguide ( 56 ) may be identified by motion amplitude of a peripheral sensor ( 24 ) exceeding that of a near-axial sensor ( 22 ). The operation of the transducer stack ( 10 ) may be controlled in response thereto. |
