Abstract

The invention discloses an ultrasonic vibration device and a design method. The problems of large cutting force, high cutting temperature, low machining precision and the like of difficult-to-machine materials such as composite materials, hard alloy and the like during machining are solved. Anultrasonic vibration auxiliary drilling and milling device is designed, a rear cover plate, piezoelectric ceramics and a front cover plate of a piezoelectric transducer are respectively made of 45 steel, PZT-8 and duralumin materials, so that good piezoelectric conversion characteristics and axial displacement output are achieved; and an ultrasonic amplitude-change pole is designed into a conical transition type composite amplitude-change pole, and the tail end of the amplitude-change pole is designed into a groove type, so that the large amplification factor is achieved, and the resonant frequency can be corrected by adjusting counterweight liquid in the groove.

Description

technical field [0001] This application relates to ultrasonic vibration assisted processing technology, combined with ultrasonic vibration technology, transforming traditional continuous processing into periodic pulse processing. Background technique [0002] In recent years, aerospace and other fields have developed rapidly, and materials such as composite materials, hard alloys, and titanium alloys have become more and more widely used. Due to the characteristics of such materials such as high hardness, high strength, and low thermal conductivity, the use of traditional machining will cause problems such as excessive cutting force and high cutting heat in the cutting area, resulting in machine tool vibration, tool wear, and chip adhesion. Make the surface quality and shape and position tolerance difficult to meet the requirements. In order to further improve the machining quality of key parts, it is urgent to propose a new machining method. [0003] Ultrasonic vibration ...
