Ultrasonic machining module

摘要

A device for use in a machining system, including an ultrasonic transducer, wherein the ultrasonic transducer is adapted to receive a tool bit; a housing adapted to be both compatible with the machining system and to receive the ultrasonic transducer, wherein the housing is operative to isolate all radial and other vibrations generated by the ultrasonic transducer except the axial vibrations transmitted to the tool bit; and a tool holder, wherein the tool holder and the top portion of the housing are mechanically coupled to one another.

1. A device for use in a machining system, comprising:
(a) an ultrasonic transducer, wherein the ultrasonic transducer is adapted to receive a tool bit, and wherein the ultrasonic transducer further comprises:
(i) a front mass;(ii) a back mass;(iii) a plurality of piezoelectric ceramics positioned between the front mass and back mass;(iv) at least one electrode sandwiched between the piezoelectric ceramics; and(v) a bolt passing through the front mass, back mass, ceramics, and electrodes, wherein the bolt is operative to apply compressive force to the ceramics; and (b) a vibration-isolating housing adapted to be both compatible with a machining system and to receive the ultrasonic transducer therein, wherein the housing further includes a spring-like feature formed radially therein above the front mass, and wherein the spring-like feature further includes a curved and thinned section of the housing, and wherein the curved and thinned section of the housing is operative to permit flexion in the housing for isolating all vibrations generated by the ultrasonic transducer when the device is in operation except axial vibrations transmitted to the tool bit, thereby preventing unwanted vibration from traveling backward or upward into the machining system.
