Abstract

The invention provides a longitudinal-torsion composite ultrasonic vibration cutting device, and belongs to the technical field of composite ultrasonic vibration cutting machining. According to the longitudinal-torsion composite ultrasonic vibration cutting device, an ultrasonic vibration longitudinal-torsion main shaft system is adopted, so that a longitudinal-torsion composite ultrasonic vibration drilling or milling is realized. The longitudinal-torsion composite ultrasonic vibration cutting device is simple in structure and convenient to install, and time and labor are saved in the machining process. The longitudinal-torsion composite ultrasonic vibration cutting device comprises a machining tool, the ultrasonic vibration longitudinal-torsion main shaft system and a clamping taper shank, wherein the machining tool, the ultrasonic vibration longitudinal-torsion main shaft system and the clamping taper shank are coaxially arranged. The ultrasonic vibration longitudinal-torsion main shaft system comprises a pre-tightening bolt, a positioning chuck, an electrode slice, an insulation sheet, an insulation sleeve, a piezoelectric ceramic piece, a torsion amplitude-change body, an amplitude-change rod and a current collecting ring. The machining tool is fixed to the bottom of the amplitude-change rod. The clamping taper shank is fixed to the top of the positioning chuck.
