Illustratively, in order to ensure electric conductivity, the first conduct piece 72, the second conduct piece 73, the first electric conductor 502 and
Two electric conductors 503 are made of copper.
In the present embodiment, in order to guarantee convenient for mounted in pairs wireless receiving component 4 and invalid emitting module 2, with reality
It is now preferably wirelessly transferred, the rotary shaft 3 includes sequentially connected shaft leading portion 34 and shaft back segment 35 from front to back, described
The outer diameter of shaft leading portion 34 is greater than the outer diameter of the shaft back segment 35, in the shaft leading portion 34 and the shaft back segment 35
Junction defines step；The wireless receiving component 4 is sheathed on outside the shaft back segment 35 and is connected at the step, from
And be able to carry out axially position, on the cylinder base 1 relative to offered at the wireless transmission component 2 annular accommodation groove 11,
The wireless transmission component 2 is set in the accommodation groove 11.
Further, in this embodiment the stable rotation in order to guarantee rotary shaft 3, the rotary shaft 3 and the cylinder base 1
Between be provided at least two bearings 9, the front end and rear end of the rotary shaft 3 are at least provided with a bearing 9.
The embodiment of second aspect of the present invention also proposes a kind of ultrasonic wave lathe comprising ultrasonic power and such as first party
The ultrasonic main shaft of face any embodiment is electrically connected between wireless transmission component 2 and ultrasonic power using conducting wire, specifically
Structure does not show that in the accompanying drawings.
Ultrasonic wave lathe in the present embodiment, due to including the ultrasonic main shaft such as first aspect embodiment, have
Whole beneficial effects of ultrasonic main shaft, therefore not to repeat here.
To sum up, the embodiment of the present invention proposes a kind of ultrasonic main shaft and the ultrasonic wave lathe including it, in cylinder base and rotation
Wireless transmission component and wireless receiving component are respectively set on axis, wireless transmission component is electrically connected with ultrasonic power, and use is non-
Ultrasonic electrical signal is transmitted in rotary shaft by the form of contact, and is arranged on pull rod is electrically connected with wireless receiving component respectively
Electrical connector, ultrasonic wave knife handle blind rivet on the conductive contact that is electrically connected with oscillator is set, be assemblied in when by ultrasonic wave knife handle
When in rotary shaft, electrical connector with only need just to be able to achieve by way of abutting between conductive contact to conduct, thus by signal
It further is transferred to oscillator from wireless receiving component, can reduce manufacture difficulty and assembly difficulty, and conduction connects at runtime
Head and the radial deflection for being electrically connected with hair life will not cause any abrasion and be lost to conductive structure, can effectively extend using the longevity
Life；Furthermore electrical connector is connected with pull rod by an elastic component, since the elastic force of elastic component acts on, can not only buffer axial
Vibration reduces axial dipole field and wears caused by conductive structure, and in the process of running, electrical connector moment elasticity can be kept to support
It is connected to conductive contact, guarantees the reliability conducted and stability.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and replacement can also be made, these are improved and replacement
Also it should be regarded as protection scope of the present invention.
