Problems solved by technology

[0004] Traditional ultrasonic-assisted machining transmits energy through the frictional contact of carbon brushes and conductive slip rings to supply power to the transducers. Therefore, carbon brushes wear quickly, heat is large, wires are exposed, carbon deposits are easy to ignite, and the tool speed cannot be too high. Problems such as automatic tool change cannot be realized

Abstract

The invention discloses a non-contact energy transmission type ultrasonic machining device. The non-contact energy transmission type ultrasonic machining device comprises a grinding head, an amplitude-change rod, a front cover plate, piezoelectric ceramic, secondary magnetic ring coil, a primary magnetic ring coil and a tool handle. The grinding head, the amplitude-change rod, the front cover plate and the tool handle are sequentially connected, the piezoelectric ceramic is arranged in a concave assembly position of the tool handle, the secondary magnetic ring coil is fixed to the front cover plate, the primary magnetic ring coil is arranged on a mechanical arm of an ultrasonic machine, and gap is formed between the secondary magnetic ring coil and the primary magnetic ring coil. The non-contact energy transmission type ultrasonic machining device is ingenious and reasonable in structural design; because of the non-contact energy transmission structure design, not only is non-contact high-efficiency transmission of electric energy achieved, but also the problem of traditional slip ring abrasion in ultrasonic machining is solved, the heat generation phenomenon caused by contact friction is avoided, the rotation speed of a spindle is increased without limitations, and meanwhile the automatic tool changing requirement of a machining center can be met; moreover, because no exposed conductors exist, electric energy transmission is not influenced by environments, and the non-contact energy transmission type ultrasonic machining device is good in working stability, safe, reliable, capable of keeping work for a long time and high in working efficiency.

Description

technical field [0001] The invention relates to the technical field of ultrasonic assisted processing, in particular to a non-contact energy transmission type ultrasonic processing device. Background technique [0002] Ultrasonic-assisted machining, as an effective composite machining method for machining difficult-to-machine materials, has been widely used in aerospace, precision instruments, optics, and medical fields. [0003] In ultrasonic assisted machining, the transducer vibrates mechanically at ultrasonic frequency and rotates at high speed with the processing tool. How to transmit the high-frequency ultrasonic electrical signal to the transducer of the high-speed rotating ultrasonic vibration unit is a prerequisite and difficulty for realizing ultrasonic-assisted machining. [0004] Traditional ultrasonic-assisted machining transmits energy through the frictional contact of carbon brushes and conductive slip rings to supply power to the transducers. Therefore, carb...
