Abstract

The invention relates to a vibration device, in particular to a bi-directional longitrorse combined vibration device. The problems that an existing vibration device is simple in vibration mode and limited in application are solved. The bi-directional longitrorse combined vibration device comprises a front cover, a first annular piezoelectric ceramic part, an installation plate, a second annular piezoelectric ceramic part, a rear cover, a first electrode end and a second electrode end, wherein one end of the front cover and one end of the rear cover are connected in an inserted mode; the first annular piezoelectric ceramic part, the installation plate and the second annular piezoelectric ceramic part are sequentially installed in the connecting position of the front cover and the rear cover from one end of the front cover to one end of the rear cover in a sleeving mode, and the first electrode end and the second electrode end are symmetrically arranged in the connecting position of the front cover and the rear cover. The bi-directional longitrorse combined vibration device is applied to the field of ultrasonic machining.

Description

technical field [0001] The invention relates to a vibrating device, in particular to a bidirectional longitudinal-torsional compound vibrating device, which belongs to the field of ultrasonic processing. Background technique [0002] In recent years, ultrasonic vibration processing has developed very rapidly, mainly because it shows advantages that traditional processing does not have in the processing of hard and brittle materials and some high-strength materials, mainly including the reduction of cutting force, the reduction of cutting temperature, and the quality of cutting surface. Good and small tool wear, etc. At the same time, ultrasonic vibration machining can make the workpiece or tool show rigidity enhancement and other effects when processing weak stiffness structures, so ultrasonic vibration machining is widely used. At present, the elliptical ultrasonic vibration turning technology, ultrasonic vibration drilling technology and rotary ultrasonic machining technol...
