It is simple and reasonable, easy to use, and clamped one time just can complete the multistage manufacturing processes to workpiece, has
It is beneficial to reduce workload, improves working (machining) efficiency and machining accuracy.
For achieving the above object, the present invention is by the following technical solutions:
A kind of high-efficiency hydraulic clamp of the present invention, including clamp base and be arranged at described clamp base
On two fixture units；It is described that described fixture unit includes that collet chuck and piston bush, described collet chuck are arranged in
In clamp base, described piston bush is sheathed between described clamp base and described collet chuck, described piston bush
Front end stretch out in the outside of described clamp base, the front end of described collet chuck is provided with some in axially arranged
Shrinking breach, the front end edge of described piston bush is axially arranged with corresponding with described contraction breach dodges breach；
The front end outer wall of described collet chuck is provided with first conical surface, and the front inner wall of described piston bush has and described first
Second conical surface of conical surface laminating；
Described clamp base is respectively equipped with the first hydraulic fluid port with described piston bush corresponding matching and the second hydraulic fluid port；
When being filled with fluid to described first hydraulic fluid port, described piston bush moves forward under oil pressure effect；When to described
When two hydraulic fluid ports are filled with fluid, described piston bush is rear under oil pressure effect to be moved.
Further, the rear end of described collet chuck is respectively arranged with installation nut and adjusting nut, described regulation
Nut supports and is located between described installation nut and described clamp base.
Further, described clamp base includes base body and the pedestal end cap being connected, described work
Plug sleeve is movably set between described base body and described pedestal end cap.
Further, the most sequentially it is embedded with first between described piston bush and described base body to prevent
Konisphere and the first sealing ring.
Further, sequentially it is embedded with second is prevented by rear to front between described piston bush and described pedestal end cap
Konisphere and the second sealing ring.
The invention have the benefit that the high-efficiency hydraulic clamp that the present invention provides, during use, by spool work
Part is inserted in the front end of collet chuck, and when being passed through hydraulic oil in the first hydraulic fluid port, piston bush is under oil pressure effect
Relative to collet chuck axial advancement, now first conical surface of the second conical surface compressing collet chuck of piston bush inwall, compels
Making contraction breach forced contraction, the aperture of collet chuck front end reduces, thus is quickly fixed by Workpiece clamping, this
Time just can be to spool workpiece milling end face radial slot and axis hole deburring；And, by shrink breach and
Dodge breach, be possible not only to convenient milling the first axial groove and the second axial groove, it is also possible to spool work
Part carries out radial bore；When being passed through hydraulic oil to the second hydraulic fluid port, piston bush under oil pressure effect relative to
The axle of collet chuck is moved back by, now the distress resolves between second conical surface and first conical surface, shrinks breach expansion
Reset, so that workpiece is released, the most just can take off spool workpiece.
In sum, present configuration arranges advantages of simple, easy to use, and steadiness is higher, not only same
Time can be with two workpiece of clamping, and each fixture unit clamped one time just can complete workpiece multiple tracks work
The processing of sequence, advantageously reduces workload, improves working (machining) efficiency and machining accuracy.

Detailed description of the invention
The present invention is further illustrated below in conjunction with the accompanying drawings.
A kind of high-efficiency hydraulic clamp as shown in Figures 2 and 3, including clamp base 1 and be arranged at fixture
Two fixture units 2 on pedestal 1；Fixture unit 2 includes collet chuck 21 and piston bush 22, collet chuck 21
Being arranged in clamp base 1, piston bush 22 is sheathed between clamp base 1 and collet chuck 21.Specifically
Saying, clamp base 1 includes base body 11 and the pedestal end cap 12 being connected, and piston bush 22 is movable
It is arranged between base body 11 and pedestal end cap 12.The front end of piston bush 22 stretches out in clamp base 1
Outside, the front end of collet chuck 21 is provided with some in axially arranged contraction breach 211, before piston bush 22
End is provided with vertically corresponding with shrinking breach 211 dodges breach 221；The front end outer wall of collet chuck 21 sets
Having first conical surface 212, the front inner wall of piston bush 22 has and second conical surface of the first conical surface 212 laminating；
Clamp base 1 is respectively equipped with the first hydraulic fluid port 13 and the second hydraulic fluid port 14 with piston bush 22 corresponding matching.
During use, spool workpiece is inserted in the front end of collet chuck 21, when being passed through liquid in the first hydraulic fluid port 13
During force feed, piston bush 22 under oil pressure effect relative to collet chuck 21 axial advancement, now in piston bush 22
First conical surface 212 of the second conical surface compressing collet chuck 21 of wall, forces contraction breach 211 forced contraction, cylinder
The aperture pressing from both sides 21 front ends reduces, thus is quickly fixed by Workpiece clamping, the most just can be to spool workpiece milling
Cut end face radial slot and axis hole deburring；And, by shrinking breach 211 and dodging breach 221, not only
Can the first axial groove of milling easily and the second axial groove, it is also possible to spool workpiece is carried out radial bore；
When being passed through hydraulic oil to the second hydraulic fluid port 14, piston bush 22 under oil pressure effect relative to the axle of collet chuck 21
It is moved back by, now the distress resolves between second conical surface and first conical surface 212, shrinks breach 211 and expand
Reset, so that workpiece is released, the most just can take off spool workpiece.
The rear end of collet chuck 21 is respectively arranged with installation nut 23 and adjusting nut 24, and adjusting nut 24 supports and sets
In installing between nut 23 and clamp base 1.By arranging adjusting nut 24, it is possible to be conveniently adjusted collet chuck
The axial location of 21, not only contributes to improve the assembly precision of the present invention, and makes to use the most square
Just.
The first dust ring 111 and the most sequentially it is embedded with between piston bush 22 and base body 11
One sealing ring 112；The second dust ring sequentially it is embedded with by rear to front between piston bush 22 and pedestal end cap 12
121 and second sealing ring 122.The effect of the first dust ring 111 and the second dust ring 121 is to prevent ash
The impurity such as dirt penetrate into the inside of clamp base 1 with piston bush 22, improve the service life of the present invention；The
The effect of one sealing ring 112 and the second sealing ring 122 is to ensure the sealing of the present invention, prevents work
Time oil liquid leakage.
The above is only the better embodiment of the present invention, therefore all according to described in present patent application scope
Structure, feature and principle done equivalence change or modify, be all included in present patent application scope
In.
