Degree, cutter chuck applicatory is taper sleeve type cutter chuck, it is characterised in that the air-floating main shaft Pneumatic tool-changing apparatus have rotation
Turn a work take offence chamber and rotation-straight line conversion assembly；There is portable plate, the portable plate is in outside gas in the rotary moveable air cavity
The rotary motion of positive and negative both direction can be made in the presence of pressure；The portable plate connects the rotation-straight line conversion assembly and drives
Rotary body rotation in the dynamic rotation-straight line conversion assembly；The rotation-straight line conversion assembly is by from the rotation of portable plate
Input conversion is in line output, and exports the straight line by parts moving linearly and be transferred to the cutter chuck, realizes knife
The conversion of tool chuck tightness.
In certain embodiments, the rotary moveable air cavity is by annular seal space, central shaft, portable plate, fixed plate, the first gas
Mouth, the second gas port composition；The annular seal space is isolated into cavity discontinuous in direction of rotation by the fixed plate；The portable plate
Around central shaft rotation；The first gas port or the second gas port are spaced between the portable plate and the fixed plate；When the first gas port
With in the second gas port do air inlet action another do exhaust event when, the portable plate from the higher-pressure region in annular seal space toward
Low-pressure area rotation in annular seal space.
In certain embodiments, the rotation-straight line conversion assembly is made up of linkage.
In certain embodiments, the rotation-straight line conversion assembly just has a screw pair, and the screw pair is just from activity
The rotation input conversion of plate is in line output.
In certain embodiments, the portable plate passes through a permission along rotary shaft to the rotation between the screw pair
To the driving member that direction is moved.
The principle of the present invention is that draught head is converted into into rotary motion using annular seal space, by rotation-straight line conversion assembly
Rotary motion is changed over into linear motion, the linear motion is acted on and change on cutter chuck gripping of the cutter chuck with respect to tapered sleeve
Amount, realizes that the change of the tightness of cutter chuck, the particularly present invention are adopted in the preferred version of screw pair, the self-locking of spiral
Effect can keep the clamping force of cutter chuck after aerodynamic force unloading, and being used as power for direction rotating screw pair need not be very big, easily
Realize that the elasticity of cutter chuck clamping force is adjusted with relatively small number of aerodynamic force, to saving gas consumption and ensureing what cutter was clamped
Self-locking is all improved.

Specific embodiment
It is understandable to enable the above objects, features and advantages of the present invention to become apparent from, embodiment will be below enumerated to this
The specific embodiment of invention elaborates.Elaborate in the following description in order to fully understand the concrete reality of the present invention
Example is applied, but, the present invention can be to implement different from mode described below, and those skilled in the art can be without prejudice to this
Similar popularization is done in the case of bright intension.Therefore, the present invention is not limited by the specific embodiment of following discloses.
As shown in figure one to figure eight, the applicable cutter chuck of the present embodiment air-floating main shaft Pneumatic tool-changing apparatus is taper sleeve type knife
Tool chuck, the taper sleeve type cutter chuck by outer surface into certain taper and be separated into three sleeve clamping part 13 and can be with
The expansion set 50 that the outer surface of the clamping part 13 coordinates is constituted, and the installation portion of cutter is placed in clamping part 13 (cutter is not drawn in figure).
When the relative expansion set 50 of clamping part 13 moves right, clamping part 13 presses little by expansion set 50, increases the clamping force to cutter；Conversely,
Reduce the clamping force to cutter.
In the present embodiment, the one end of pneumatic department 30 has a planar wall, and axis hole is opened up on the planar wall, and one is fixed on
The fixed plate 32 of planar wall and the ring wall of pneumatic department 30, an air cavity lid 70 coordinated with above-mentioned end and the end composition rotary moveable
Air cavity 33.The portable plate 40 being placed in rotary moveable air cavity 33 is installed by rotating shaft 20, be able to can be made in the presence of external pressure
The rotary motion of positive and negative both direction.The rotating shaft 20 drives cutter chuck 10 to rotate by slide key, the spiral of cutter chuck 10
Composition rotation-straight line the conversion assembly of screw pair 31 of pair 11 and pneumatic department 30, wherein, rotating shaft 20 and cutter chuck 10 constitute rotation
Swivel.The rotation-straight line conversion assembly is changed into higher level's rotary motion to move along a straight line and export gives subordinate's driving member --- this
It is connecting rod 12 in embodiment.The connecting rod 12 is delivered to linear motion on clamping part 13, drive clamping part make to the left or to
Right motion.
Such as Fig. 8, when 72 the first air inlet of air inlet of the second air inlet 71 is vented, include between fixed plate 32 and portable plate 40
The region of the second air inlet 72 becomes higher-pressure region, and the region comprising the first air inlet 71 becomes between fixed plate 32 and portable plate 40
Low-pressure area, then portable plate 40 and be rotate counterclockwise as shown in Figure 8 from higher-pressure region toward low-pressure area rotation.When portable plate 40 such as
When rotating counterclockwise shown in Fig. 8, the rotation-straight line conversion assembly being made up of a pair of screw pairs becomes the rotate counterclockwise
Change linear motion to the right into, increased clamping force of the clamping section 13 to cutter.
The above, is only presently preferred embodiments of the present invention, and any pro forma restriction is not made to the present invention.Appoint
