Accessory non-contact power supply type rotary ultrasonic machining device

Abstract

The invention relates to an accessory non-contact power supply type rotary ultrasonic machining device belonging to the technical field of precision machining of hard brittle materials and aiming at promoting a common machine tool to an ultrasonic auxiliary rotary machining machine tool capable of carrying out the precision machining of the hard brittle materials without changing the traditional part of the machine tool. The accessory non-contact power supply type rotary ultrasonic machining device comprises a direct digital frequency synthesis ultrasonic generator with frequency automatic-tracking function, an ultrasonic tool shank with a standard main shaft interface, and an ultrasonic vibration system, wherein the ultrasonic vibration system is integrated in the ultrasonic tool shank on the basis of the ultrasonic tool shank and adopts a non-contact electromagnetic conversion type power supply method; and the ultrasonic tool shank is integrated on a main shaft of the common machine tool through the standard main shaft interface. The invention is mainly used for the design and the manufacture of a precision machining device of the hard brittle materials.

Description

technical field [0001] The invention belongs to the technical field of precision machining of hard and brittle materials, in particular to the preparation of an accessory type non-contact power supply rotary ultrasonic processing device. Background technique [0002] The wide application of hard and brittle materials in various fields has increased the processing requirements of hard and brittle materials. The characteristics of hard and brittle materials such as poor machinability, high strength and easy damage make it difficult to obtain good processing results by ordinary processing methods. Traditional processing methods can no longer meet the production and manufacturing requirements of hard and brittle materials. The research and development of special processing technology and equipment related to hard and brittle materials processing represents the development direction of current manufacturing technology. As a special processing technology, the development of rotar...

Problems solved by technology

The current rotary ultrasonic machining equipment mostly uses contact brushes for power supply, which has the following two main disadvantages: large changes to the machine tool spindle, serious brush wear and easy out-of-step during high-speed rotation

Using an accessory type non-contact power supply rotary ultrasonic machining device can solve these problems very well, and can make the system miniaturized and portable. However, the current device is an overall structure integrated into the machine tool spindle, which is not suitable for the transformation and maintenance of existing machine tools. upgrade
