ULTRASONIC CUTTER HANDLE, CUTTER CLAMPING STRUCTURE, MACHINING DEVICE, AND MACHINE TOOL

WIPO Patent Application WO/2023/070818

A1

Disclosed in the present invention are an ultrasonic cutter handle, a cutter clamping structure, a machining device, and a machine tool. The ultrasonic cutter handle comprises an amplitude transformer and a cutter clamping structure which are sequentially connected to a cutter handle body, wherein the cutter clamping structure comprises a cutter clamping section and a cutter handle connecting section which are connected to each other, and a longitudinal-torsional conversion unit is arranged on an outer peripheral face of the cutter clamping section. Compared with the prior art in which a longitudinal-torsional conversion unit is arranged on an amplitude transformer, the longitudinal-torsional conversion unit in the present application is configured to convert longitudinal vibrations transmitted by the amplitude transformer into composite longitudinal-torsional vibrations, so that one-dimensional machining is converted into two-dimensional machining, the service life of a cutter is further prolonged, the machining efficiency is improved, and the surface roughness of a machined workpiece is improved.
