The tool shank structure comprises a machine tool, a tool shank casing rotationally mounted on the machine tool, and an ultrasonic system mounted in the tool shank casing, wherein the ultrasonic system comprises an amplitude-change pole; the front end of the amplitude-change pole is fixedly connected with the tool shank casing; the tool shank structure further comprises a first annular magnet mounted in the tool shank casing and a second annular magnet mounted at the rear end of the amplitude-change pole; the second annular magnet is positioned in the first annular magnet; the polarity of the inner surface of the first annular magnet is the same as that of the peripheral surface of the second annular magnet; the rear end of the amplitude-change pole can be relatively fixed with the tool shank casing in the radial direction in a non-contact way through the effect that the same polarities of the first annular magnet and the second annular magnet mutually repel. The tool shank structure improves the stability and the radial stiffness of the ultrasonic system, further improves the machining precision, and can neither influence the transmission of axial ultrasonic vibration wave nor cause ultrasonic energy loss and heating of the system.
Description
Technical field
