Rotary body rotation in dynamic described rotation-straight line conversion assembly；Described rotation-straight line conversion assembly is by the rotation from portable plate
Input conversion is in line output, and exports described straight line by parts moving linearly and be transferred to described cutter chuck, realizes knife
The conversion of tool chuck tightness.
In certain embodiments, described rotary moveable air cavity is by annular seal space, central shaft, portable plate, fixed plate, the first gas
Mouth, the second gas port composition；Described annular seal space is isolated into cavity discontinuous in direction of rotation by described fixed plate；Described portable plate
Around the rotation of described central shaft；It is spaced the first gas port or the second gas port between described portable plate and described fixed plate；When the first gas port
With one of the second gas port do air inlet action another do exhaust event when, described portable plate from the higher-pressure region in annular seal space toward
Low-pressure area rotation in annular seal space.

In certain embodiments, described portable plate passes through a permission along rotary shaft to the rotation between described screw pair
The driving member moving to direction.
Principle of the present utility model is, using annular seal space, draught head is converted into rotary motion, by the conversion of rotation-straight line
Rotary motion is changed over linear motion by assembly, and this linear motion acts on and changes cutter chuck on cutter chuck relative to tapered sleeve
Gripping amount, realizes the change of the tightness of cutter chuck, particularly the utility model adopts in the preferred version of screw pair, spiral shell
The self-locking action of rotation can keep the clamping force of cutter chuck after aerodynamic force unloading, and being used as power that direction rotating screw is secondary need not be very
Greatly, easily adjusted with the elasticity that relatively small number of aerodynamic force realizes cutter chuck clamping force, to saving gas consumption and guarantee knife
The self-locking of tool clamping is all improved.

Specific embodiment
Understandable for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below will enumerate embodiment
Specific embodiment of the present utility model is elaborated.Elaborate in the following description in order to fully understand this practicality
New specific embodiment, but, the utility model can be to implement different from mode described below, those skilled in the art
Similar popularization can done without prejudice in the case of the utility model intension.Therefore, the utility model is not had by following discloses
The restriction of body embodiment.
As shown in figure one is to figure eight, the cutter chuck that the present embodiment air-floating main shaft Pneumatic tool-changing apparatus are suitable for is taper sleeve type knife
Tool chuck, this taper sleeve type cutter chuck by outer surface become certain taper and be separated into three sleeve clamping part 13 and can be with
The expansion set 50 of the outer surface cooperation of this clamping part 13 forms, and the installation portion of cutter is placed in clamping part 13 (in figure does not draw cutter).
When expansion set 50 moves right clamping part 13 relatively, clamping part 13 is pressed little, the clamping force to cutter for the increase by expansion set 50；Conversely,
Reduce the clamping force to cutter.
In the present embodiment, the one end of pneumatic department 30 has a planar wall, this planar wall opens up axis hole, one is fixed on
Planar wall and the fixed plate 32 of pneumatic department 30 ring wall, one forms rotary moveable with the air cavity lid 70 of above-mentioned end cooperation and this end
Air cavity 33.The portable plate 40 being placed in rotary moveable air cavity 33 is installed by rotating shaft 20, can be able to make in the presence of external pressure
The rotary motion of positive and negative both direction.This rotating shaft 20 drives cutter chuck 10 to rotate by slide key, the spiral of cutter chuck 10
The screw pair 31 composition rotation-straight line conversion assembly of pair 11 and pneumatic department 30, wherein, rotating shaft 20 and cutter chuck 10 constitute rotation
Swivel.This rotation-straight line conversion assembly higher level's rotary motion is changed into move along a straight line and export to subordinate driving member this
It is connecting rod 12 in embodiment.Linear motion is delivered on clamping part 13 this connecting rod 12, drive clamping part make to the left or to
Right motion.
As Fig. 8, when the second air inlet 72 air inlet the first air inlet 71 is vented, comprise 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 between fixed plate 32 and portable plate 40 becomes
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, this rotate counterclockwise is become by the rotation-straight line conversion assembly being made up of a pair of screw pair
Change linear motion to the right into, increased the clamping force to cutter for the clamping section 13.
