The effect of.
One embodiment of the utility model provides a kind of external wireless transmission mechanism comprising:One rotation section, has
An at least first coil, first coil are electrically connected to a ultrasonic cutter;Wherein, rotation section is movably connected on a high-accuracy master
At the wholeheartedly shaft tail end of axis;And a shell, it is set on the outside of rotation section, and rotation section can be relatively rotated in enclosure interior,
The second coil being oppositely arranged with the first coil at least one in shell so that the first coil and second line
Wireless transmission electric signal is able between circle.
Further, second coil loop is set at the outer peripheral edge of the first coil.
Further, the first coil is arranged with second coil for parallel side-by-side.
Further, which is equipped with an at least Signal connector, the Signal connector and the second coil electrical couplings.
Further, an at least bearing is equipped between the rotation section and shell.
Further, which is equipped at least one for being connected to the lock hole part of a board.
Further, which is equipped with an axis hole.
Further, which is equipped with a perforation, which is concentric setting with the axis hole.
Whereby, which can be directly mounted at the mandrel tail end of general high-accuracy main shaft, peace
Holding position is not only easy to install or reequip existing high-accuracy main shaft, for the high-accuracy main shaft producer, without setting again
Meter modification original production line.And entirety is placed outside at high-accuracy main shaft tail, can directly remove repair or replacement, it is high without changing
Accurate main shaft position, reducing, which influences main shaft precision problem, generates.

Specific implementation mode
For ease of illustration the central idea represented by the utility model content, is now expressed with specific embodiment.In embodiment
Various difference objects are drawn in the ratio suitable for enumerating explanation, rather than in the ratio of actual component.
Refering to Figure 1, the utility model provides a kind of external wireless transmission mechanism, it is installed on a high-accuracy master
On axis 1, which is set to the mandrel 3 in axle sleeve 2 including an axle sleeve 2 and one, which has one for installing
The head end 4 of ultrasonic cutter and a tail end 5, and 3 axle center of mandrel is run through equipped with a channel axis hole 6, the channel axis hole 6 is for peace
Dress broaching tool bar group (not shown) is used for cutting fluid water outlet.
Also, external wireless transmission mechanism includes:
One rotation section 10 is movably connected at 3 tail end 5 of mandrel of the high-accuracy main shaft 1;Rotation section 10 has at least one
First coil 11, the first coil 11 is electrically connected to the ultrasonic cutter at head end 4, such as is passed through using a signal wire
Channel axis hole 6 is to be electrically coupled to ultrasonic cutter;And
One shell 20 is set to 10 outside of rotation section, and shell 20 is in generally a hollow housing shape, and the rotation section 10 is arranged
And can be relatively rotated in 20 inside of shell, such as an at least bearing 30 is equipped between the rotation section 10 and shell 20, it is rotated with profit.
The second coil 21 being oppositely arranged with the first coil 11 at least one in the shell 20 so that the first coil 11 with
Electromagnetic change sensing transmission electric signal is able between second coil 21, to achieve the purpose that wireless way for transmitting.This is electrical
Signal include electric power, control signal or sensing signal at least one.Wherein, second coil 21 is located on described first
