The air floating structure of said structure with respect to existing air floating structure, by opening on the outer circumference surface of air suspension shaft sleeve 3
If cannelure 4, and air inlet is made to connect with cannelure 4, venthole 6 is connected with the outer circumference surface of air suspension shaft sleeve 3, so that by
The pressure-air that air inlet 5 enters is entered between air suspension shaft sleeve 3 and main shaft body 2 by the micropore on cannelure 4 bottom land
In annular space, and via the micropore on air suspension shaft sleeve 3, enter in the venthole 6 being connected with air suspension shaft sleeve 3 outer circumference surface, and
Discharged outside ultrasonic main shaft by venthole 6.Because the micropore on air suspension shaft sleeve 3 is evenly distributed, therefore can be in annular space
Form uniform air film, and due to air suspension shaft sleeve 3 for the length of micropore given vent to anger than the micropore for air inlet length
Grow, therefore go out atmidometer and be greater than intake resistance, thus can be formed in annular space and there is certain bearing capacity and stiffness
Lubrication air film.Simultaneously because the air in annular space is flowing, the gas of flowing can be taken away and be revolved due to main shaft body 2
Then the heat producing, therefore can ensure that main shaft body 2 is stable and rotate.
Further, so that in annular space the gas of distribution more uniformly and ensure the intensity of air suspension shaft sleeve 3,
With reference to shown in Fig. 5, described cannelure 4 be arranged in parallel, and is linked together by translot 7 between described cannelure 4, described horizontal stroke
Groove 7 is opened in the outer surface of described air suspension shaft sleeve 3.
In the present invention, due to multiple cannelures 4 being offered on the outer circumference surface of air suspension shaft sleeve 3, therefore decrease air supporting
Axle sleeve 3 and the contact area of main shaft sleeve 1, simultaneously because need to keep the permeability of the micropore on air suspension shaft sleeve 3, therefore air supporting
Can not be using gluing fixed form, in order to securely air suspension shaft sleeve 3 is fixed on spindle shaft between axle sleeve 3 and main shaft sleeve 1
Put it is preferable that the outer circumference surface of the endoporus of described main shaft sleeve 1 and described air suspension shaft sleeve 3 is taper seat, by being set to justify
The main shaft sleeve 1 of pyramidal structure and air suspension shaft sleeve 3, can make main shaft sleeve 1 be fitted close with air suspension shaft sleeve 3 when mounted, from
And ensure the two fastness connecting.
In the present invention, the axially position of described main shaft body 2 can be realized by actuator (as motor).
Described main shaft body 2 realizes positioning radial through air film, and it axially can realize by actuator positioning.
In order to better ensure that main shaft body 2 axially position, improve the stability of ultrasonic main shaft, preferred in the present invention
In embodiment, as shown in Figure 2 and Figure 3, the outer circumference surface of described main shaft body 2 is further fixed on axially position ring 8, in described master
First graphite locating ring 9 and the second graphite locating ring 10, described first graphite locating ring 9 He are also installed with axle axle sleeve 1
There is gap, described axially position ring 8 is located at described first graphite between the inwall of the second graphite locating ring 10 and main shaft body 2
Between locating ring 9 and the second graphite locating ring 10, and two end faces of described axially position ring 8 are positioned with the first graphite respectively
Ring 9 contacts with the second graphite locating ring 10.
Wherein said axially position ring 8 can be structure as a whole with described main shaft body 2, by carrying out to main shaft body 2
Machining is formed it is also possible to axially position ring 8 is fixed on main shaft body 2 by modes such as welding.For the ease of described
The fixation on described main shaft sleeve 1 of one graphite locating ring 9 and the second graphite locating ring 10, described axially position ring 8 is located at institute
State the side of air suspension shaft sleeve 3, in the present embodiment, described axially position ring 8 is located at the left side of described air suspension shaft sleeve 3.
Connect with the left and right both ends of the surface of axially position ring 8 respectively by the first graphite locating ring 9 and the second graphite locating ring 10
Touch, it is possible to achieve the axial restraint of main shaft body 2, improve the stability of ultrasonic main shaft work.Simultaneously because the first graphite is fixed
Position ring 9 and the second graphite locating ring 10 are all made using graphite, and it has self-lubricating property, therefore can reduce main shaft body 2
Frictional force between first graphite locating ring 9 and the second graphite locating ring 10 and axially position ring 8 during rotation.
In the present invention, described actuator be for drive shaft body 2 rotation, therefore can using various can be defeated
Go out the driving structure of rotary motion.
So that the structure of ultrasonic main shaft that the present invention provides is simple, compact, working stability is it is preferable that with reference to figure
