Outer peripheral face.Described first chute 11 interlocks around this axis hole 10 with described second chute 12
Arrangement.
This brake 2 is axially displaceably installed in this axis hole 10 of this body 1, and with
One machine-tool (not shown) links.This brake 2 can be driven by the control of this machine-tool
In this axis hole 10 of this body 1, this body 1 relative moves back and forth vertically.This brake 2
Generally in flat cylindric, and there is an axle center part 21 and six around being arranged at intervals at this axle
The stopper portion 22 of the outer peripheral face in heart portion 21.Each stopper portion 22 is adjacent to two adjacent stopper portions
An inclined thrust surface group 220 it is respectively formed with at 22.Each inclined thrust surface group 220 has along this
Body 1 radially spaced every and first inclined thrust surface 221 being oppositely arranged and second cant
Face 222.
Described fixture 3 is slidedly arranged on described first chute 11 respectively, and each fixture 3 includes one
Individual pawl seat 31 and a jaw 32.Each pawl seat 31 is installed on the first chute 11 of correspondence
In and have one connect this brake 2 by stopper portion 33 so that each pawl seat 31 can
Controlled to drive by this brake 2 and move back and forth in the first corresponding chute 11 of this body 1.
Each is positioned between described stopper portion 22 wherein two neighbors by stopper portion 33, and has
The oblique surface group 330 of two inclined thrust surface groups 220 abutting corresponding two stopper portions 22 respectively.Often
One oblique surface group 330 has and is reversed and can contact at corresponding inclined thrust surface group 220 respectively
This first inclined thrust surface 221 and first oblique surface 331 and of this second inclined thrust surface 222
Individual second oblique surface 332.By described oblique surface group 330 respectively with described inclined thrust surface group 220
Match so that this brake 2 along the axial reciprocating of this body 1 move time, described pawl seat 31
Can by this brake 2 stopper, radial direction along this body 1 moves back and forth simultaneously.
Each jaw 32 can be locked in correspondence with adjusting position along the radial direction of this body 1
Can move along with this pawl seat 31 on pawl seat 31 end face.The end face of each pawl seat 31 is concavo-convex
It is formed with the upper denture structure 311 that an arranged radially along this body 1 extends, each folder
The bottom surface of pawl 32 is concavo-convex be formed with one can be with upper denture structure 311 phase of corresponding pawl seat 31
Ratcheting lower tooth array structure 321.Each jaw 32 passes through its lower tooth array structure 321 with corresponding
The upper denture structure 311 of pawl seat 31 matches and arranges in both connections, can conveniently adjust
Position and location are set so that locking operation.
Described dust-proof piece 4 described second chute 12 being the most removably embedded at this body 1,
During for preventing dust or work pieces process, produced cutting swarf lodges in described second chute 12
In.
This dust cap 5 is removably locked in this body 1 and has described first chute 11 and institute
State the side of the second chute 12, and cover cap lives one end of this axis hole 10 of this body 1, is used for
In when avoiding dust or work pieces process, produced cutting swarf enters this axis hole 10 of this body 1
And affect the running of this brake 2 or other components, or cause this brake 2 or other components
Damage.
After above-mentioned Null oil-pressure chuck uses a period of time, above-mentioned each fixture 3 is at this body 1
In each first chute 11 slipping, each first chute 11 that meeting is set with in this body 1
Surface contact friction thus produce abrasion, the once shape of each first chute 11 of this body 1
Shape is because of abrasion deformation, and when firmly cannot be disposed therein for each fixture 3, then can cause institute
Stating fixture 3 for workpiece is in unsteady clamp position, and then impact is for the processing of workpiece
Operation and machining accuracy, now user only described fixture 3 all need to be eliminated change into new, and
Dust-proof piece 4 that is embedded at described second chute 12 respectively is unloaded, then by new described fixture 3
Be respectively arranged in standby described second chute 12 and be connected with this brake 2, the most again
Dust-proof piece 4 unloaded is embedded at described first chute 11 respectively, is used for preventing dust or workpiece from adding
Cutting swarf produced by man-hour lodges in described first chute 11, improves this body 1 whereby
To twice service life and allow described fixture 3 can be held fixedly workpiece, it is thus possible to effectively shorten
Eliminate the time of changing and reduction is eliminated and changed this into, therefore really can reach the purpose of this utility model.
It is noted that this utility model embodiment is disclosed that the sky of a kind of three fingers
Oil-pressure clamping head, but be not limited, it is possible to the Null oil-pressure for two fingers as shown in Figure 5 presss from both sides
Head, namely the first chute 11 of this body 1 and the quantity of the second chute 12 are respectively two,
Thus respectively for two fixture 3 installation settings.
As described above, embodiment the most of the present utility model, when not limiting this with this
The scope that utility model is implemented, the most all according to this utility model claims and description institute
The simple equivalence made changes and modifies, and the most still belongs to scope of the present utility model.
