ROTARY ULTRASONIC MACHINING DEVICE CAPABLE OF EXPANDING BANDWIDTH

WIPO Patent Application WO/2021/120329

A1

Disclosed is a rotary ultrasonic machining device capable of expanding bandwidth, the device comprising a transducer (1), a cutter (2) and a combined cutter holder (3), wherein one end of the combined cutter holder (3) is connected to the transducer (1), and the other end of the combined cutter holder is connected to the cutter (2); the combined cutter holder (3) comprises sleeve parts and rod-shaped parts, the sleeve part and a corresponding rod-shaped part are capable of being coaxially connected in parallel, or partially connected in series and partially connected in parallel, and two rod-shaped parts are capable of being coaxially connected in series in a contact manner by means of end faces, so as to form the required combined cutter holder (3); during parallel connection, the sleeve part is sleeved on a matched rod section of the rod-shaped part, and an inner surface of a parallel section is in contact fit with an outer circular surface of the rod section; and the sleeve parts and/or the rod-shaped parts are made of damping materials with different damping coefficients. The device can expand the bandwidth of a vibration system by replacing components made of materials with different damping coefficients.
