Further, provided with the between centers gap for meeting piston stroke between the piston and oil cylinder cover.
Further, gas mould guard circle is also associated with the chuck body.
Further, it is provided with the first dust cap on the outside of the clamping slip cap, and the clamping slip cap and first dust-proof Provided with the between centers gap for meeting clamping slip cap stroke between lid.
Further, the spring uses stack-type spring.
Further, the axle center of the chuck body is provided with workpiece positioning sleeve.
Further, the second dust cap and elastic ring are provided with the outside of the claw.
Beneficial effect:Compared to the prior art, design is unique, small volume by the present invention, and chucking power is big, easy to adjust, repeats Property and it is dominant good again, action response is fast, and one group of asymmetric circular arc claw is to workpiece without impression, and service life is long.
Brief description of the drawings
Fig. 1 is structure sectional view of the invention.
Embodiment
Technical scheme is described in further detail with reference to specific embodiments and the drawings.
A kind of numerically-controlled precise cylindrical grinder high-precision hydraulic chuck as shown in Figure 1, including chuck body 1, spring 4, Side in spring bolt 5, clamping slip cap 6, claw 10, oil cylinder ejector pin 11, piston 12 and oil cylinder cover 13, the chuck body 1 Provided with reciprocating piston 12, the outside of piston 12 is provided with oil cylinder cover 13, and the inner side of piston 12 passes through oil cylinder top respectively Pin 11 is connected with multiple reciprocating clamping slip caps 6, in the presence of oil cylinder ejector pin 11, promotes to clamp slip cap 6 It is reciprocating.It is described to clamp the stack-type spring spiral shell that stack-type spring 4 and the fixed stack-type spring 4 are provided with slip cap 6 Bolt 5, the clamping slip cap 6 is flexibly connected with claw 10 by wedge type groove.
It is used as the further optimization of the present embodiment:
It is preferred that, it is provided with order to ensure the normal reciprocating motion of piston 12, between the piston 12 and oil cylinder cover 13 and meets piston The between centers gap of 12 strokes.
It is preferred that, gas mould guard circle 2 is also associated with the chuck body 1, is blown outward by gas and does not allow dust to enter.
It is preferred that, in order to dust-proof, the first dust cap 3 is provided with the outside of the clamping slip cap 6, and slide for the ease of clamping Set 6 moves back and forth, described to clamp the between centers provided with the satisfaction clamping stroke of slip cap 6 between the dust cap 3 of slip cap 6 and first Gap.
It is preferred that, in order to improve service life, the spring 4 uses stack-type spring.
It is preferred that, the axle center of the chuck body 1 is provided with workpiece positioning sleeve 7, the axially position for workpiece.
It is preferred that, the outside of claw 10 is provided with the second dust cap 8 and elastic ring 9, and the dust ring 8 of elastic ring 9 and second is true Protect when claw 10 is acted and do not drop.
The operation principle of the present invention(Process)It is specific as follows:
The present invention promotes piston by the effect of oil cylinder external force, and piston promotes clamping slip cap 6 to move reciprocatingly, clamps slip cap 6 Reciprocating motion so as to driving claw to act the clamping and release of workpiece.Claw has five and four using one group of structure, claw Individual two kinds, and be arc contact, to workpiece fanout free region.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention, though So the present invention is disclosed above with preferred embodiment, but is not limited to the present invention, any to be familiar with this professional technology people Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification For the equivalent embodiment of equivalent variations, as long as being the content without departing from technical solution of the present invention, the technical spirit according to the present invention Any simple modification, equivalent variations and the modification made to above example, in the range of still falling within technical solution of the present invention.
