Abstract

The invention discloses an ultrasonic processing device, in particular to a high-speed rotary ultrasonic torsional processing device which comprises an output shaft and a transmission shaft. A rare-earth rod and tubular piezoelectric ceramic are mounted in an inner bore of the output shaft from inside to outside along an axial direction sequentially. An induction coil is wound on the output shaft, a coil former and an outer sleeve are arranged on the outer side of the transmission shaft, a closed coil storage chamber is formed by the coil former and the outer sleeve, and an excitation coil is disposed in the coil storage chamber. The ultrasonic torsional processing device which is manufactured on the basis of rare earth magnetostriction materials and piezoelectric ceramic materials is connected with a spindle of a machine, is subjected to two-dimensional ultrasonic mechanical vibration while driving a tool head to rotate at high speed, and thus, ultrasonic torsional processing of workpieces is achieved. Besides, the device realizes high-speed rotary ultrasonic torsional processing, ultrasonic frequency band is wide, ultrasonic energy is high, running state is stable, ultrasonic vibration amplitude can be regulated by changing magnetic field intensity and prepressure, and accordingly requirements of different processing precisions can be met.

Description

technical field

[0001] The invention relates to an ultrasonic processing device, in particular to a high-speed rotating ultrasonic torsional vibration processing device. Background technique

[0002] At present, many new materials and multifunctional materials, such as SiC, NdFeB, and functional ceramics, are widely used in the fields of high-tech precision components such as industrial engineering, optical engineering, automobile industry, and aerospace engineering, but these materials are generally brittle. The characteristics of hard and difficult machining, the use of traditional metal processing technology is easy to cause tool wear, burns and damage to the workpiece, it is difficult to achieve the required accuracy, and the processing efficiency is low. Ultrasonic vibration processing technology is a combination of ultrasonic vibration and tool or The new processing technology combining workpieces has lower cutting force, lower cutting temperature and higher processing...
