ROTARY ULTRASONIC GRINDING MACHINE TOOL AND APPLICATION

Document Type and Number:

WIPO Patent Application WO/2022/222280

Kind Code:

A1

Abstract:

A rotary ultrasonic grinding machine tool, comprising a rotary ultrasonic grinding spindle (1), an ultrasonic power transmission device (2), a spindle clamping and lifting device (3), and a part clamping and feeding device (4), wherein the rotary ultrasonic grinding spindle (1) comprises a grinding wheel (101) mounted at an output end of an amplitude transformer (103); a mandrel at a large end of the amplitude transformer (103) extends into a hollow sleeve (106) to be connected to an output end face of a transducer (107); the transducer (107) is connected to an inner surface of the hollow sleeve (106) in a transition fitting manner by means of a positioning flange (109); the hollow sleeve (106) is mounted in a supporting base (102); and a tail end of the hollow sleeve (106) is connected to an electric spindle (112) by means of a coupler (111). Further comprised is a method for using the rotary ultrasonic grinding machine tool. The rotary ultrasonic grinding spindle is directly driven by the electric spindle, thereby improving the grinding efficiency, reducing the grinding force and grinding heat, and improving the part machining quality.
