Ultrasonic vibration pneumatic drill based on rotary type wireless electric power transmission

Abstract

The invention discloses an ultrasonic vibration pneumatic drill based on rotary type wireless electric power transmission. The ultrasonic vibration pneumatic drill comprises a rotary wireless electric power transmission assembly, an ultrasonic transduction assembly, an amplitude-change pole, a spring chuck assembly and a connecting assembly, wherein the rotary wireless electric power transmission assembly is used for realizing electric power transmission between two mechanisms rotating oppositely and comprises a wireless electric power transmission primary unit and a wireless electric power transmission secondary unit; the ultrasonic transduction assembly is used for converting ultrasonic-frequency electric signals into ultrasonic-frequency mechanical vibration; the ultrasonic vibration amplitude-change pole is used for amplifying small-amplitude mechanical vibration into large-amplitude mechanical vibration to meet requirements of ultrasonic vibration drilling machining; the spring chuck assembly is used for clamping tools; the connecting assembly is used for connecting ultrasonic vibration drilling parts with the rear end of the pneumatic drill so as to realize power transfer and electric power transmission. Ultrasonic vibration is applied to the traditional drilling machining process, and a combined machining mode of coupling of ultrasonic vibration and traditional drilling motion is formed, so that machining quality is effectively improved and machining efficiency is improved.
