A non-contact energy transfer device for rotary ultrasonic machining

Abstract

The invention discloses a non-contact energy transmission device for rotary ultrasonic processing. The non-contact energy transmission device comprises a fixed end and a rotating end. The opposite positions of the fixed end and the rotating end are each of an axial opened type or a radial opened type. When the opposite positions of the fixed end and the rotating end are of the axial opened type, a magnetic core of the fixed end is a part cut from a tank type magnetic core, and the central angle of the part cut from the tank type magnetic core is smaller than or equal to 180 degrees; a magnetic core of the rotating end is a complete tank type magnetic core. When the opposite positions of the fixed end and the rotating end are of the radial opened type, the magnetic core of the fixed end is a part cut from an annular inner groove magnetic core, and the central angle of the part cut from the annular inner groove magnetic core is smaller than or equal to 180 degrees; a magnetic core of the rotating end is a complete annular outer groove magnetic core. By means of the non-contact energy transmission device, the processing efficiency and automation level can be improved, the improvement cost and capital investment can be saved, the safety and applicability of an ultrasonic processing device can be improved, and the installation performance and adjustment performance are good.

Description

technical field [0001] The invention belongs to the technical equipment field of rotary ultrasonic processing, and in particular relates to a non-contact energy transmission device for rotary ultrasonic processing. Background technique [0002] Rotary ultrasonic machining technology is a processing method based on traditional rotary machining technology and combined with ultrasonic vibration to achieve material removal. Rotary ultrasonic machining can effectively reduce cutting force, reduce tool wear, and improve material removal rate, especially for difficult-to-machine materials. Therefore, rotary ultrasonic machining technology is widely used in the processing of hard and brittle materials such as ceramics and glass, as well as difficult-to-machine materials such as fiber-reinforced composite materials. [0003] Rotary ultrasonic machining methods mainly include: rotary ultrasonic milling, rotary ultrasonic grinding, rotary ultrasonic turning, rotary ultrasonic drilling...

AI Technical Summary

Problems solved by technology

This frequent manual tool change process reduces the processing efficiency and the automation level of production; if you want to realize the automatic tool change function, you need to carry out a lot of transformation on the machine tool itself or the tool change mechanism, and the transformation cost and capital investment are huge; In addition, The introduction of human factors such as manual tool change and the relatively closed energy transmission space are not conducive to the safety of the processing process.

The existing non-contact energy transmission device also has disadvantages such as poor adaptability to different machine tools and different tool holder structures, and inconvenient installation and debugging.
