Abstract

The invention discloses a single-excitation longitudinal-twisted compound vibration converting device comprising a first converter and a second converter, wherein one end of the first converter and one end of the second converter are matched by abutting and pressing through a mode of a tenon-and-mortise structure, and an axial fixing mechanism is also arranged between the first converter and the second converter. The single-excitation longitudinal-twisted compound vibration converting device has a reasonable design, a simple structure, strong practicability and extensive market prospect, is easy to realize longitudinal-twisted compound vibration, can be applied to the field of ultrasonic compound processing and is easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic machining, in particular to a single excitation longitudinal-torsional compound vibration conversion device. Background technique [0002] Traditional ultrasonic machining mostly adopts a single longitudinal vibration or torsional vibration or bending vibration mode. In order to expand the scope of ultrasonic application and improve its application effect, a single vibration can be combined, that is, longitudinal-bending, longitudinal-torsional and bending-torsional composite vibration modes. The commonly used longitudinal-bending and longitudinal-torsional composite vibration modes are ultrasonic machining. . Composite vibration modes have been proved by experiments to obtain better quality than single vibration processing in both cutting and welding processing. [0003] The existing devices for realizing longitudinal-torsional compound vibration can be divided into two categories, one is to...
