Description
Technical field
It the utility model is related to a kind of vertical multi-stage axis hole honing fixture, more particularly to a kind of hydraulic valve body axis hole top gem of a girdle-pendant
Grind three-dimensional air pressure suspension honing fixture.
Background technology
Digital control vertical multi-station honing machine, the high-precision honing for hole are processed, it is impossible to reach hydraulic valve body axis hole height
Precision.Reason is multistation honing fixture on digital control vertical honing machine, is fixed in work disk, produced various attachment means
Positioning cumulative errors it is bigger, when centerline hole of the honing reamer along hydraulic valve enters fashionable, external carbuncle ripple suffered by reamer
It is dynamic big.Fraising is caused to bear to produce the bounce of bore deformation error cutting force, this problem influences hydraulic valve axis hole machining accuracy
It is required that.
Utility model content
In order to solve the above problems, the utility model provides a kind of hydraulic valve body axis hole honing three-dimensional air pressure suspension clamp
Tool.Three-dimensional air pressure suspension fixture theory structure, can eliminate multistation honing reamer influences in external carbuncle caused by process, protects
Demonstrate,prove the requirement of hydraulic valve body axis hole machining accuracy.
The technical solution of the utility model：A kind of hydraulic valve body axis hole honing three-dimensional air pressure suspension fixture, including bottom plate,
There is chute air pressure suspension bearing, positioning seat, pressing plate and axially position axle, bottom plate both sides, and air pressure suspension bearing is arranged on bottom plate, gas
Include air pressure suspension annulus in pressure suspension bearing, respectively there are a radial direction keyway, upper and lower face diameter in the above and below of air pressure suspension annulus
Stagger 90 degree of angles to keyway, feather key is installed in radial direction keyway, positioning seat is arranged on air pressure suspension annulus and suspended with air pressure
Bearing is not contacted, and air pressure suspension annulus, air pressure suspension bearing and positioning seat are on same datum plane, the installation of axially position axle
On positioning seat, the top braces of axially position axle are arranged on positioning seat in the bottom surface of the pressing plate, pressing plate by bridge screw
On.
Further, bottom plate is rectangular.
Further, air pressure suspension annulus cross section is rectangular configuration.
It is of the present utility model to be beneficial in that：Modularized design combination, can seriation kind configuration, error is diminished,
Air pressure suspension high sensitivity, Three-Dimensional Dynamic stress variation are small, the honing accuracy of hydraulic valve body through hole is high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is top view of the present utility model；
Fig. 3 is air pressure suspension bearing structure illustration.
Wherein：1st, hydraulic valve body, 2, chute, 3, bottom plate, 4, air pressure suspension bearing, 5, positioning seat, 6, honing reamer enters
Enter hole, 7, pressing plate, 8, bridge screw, 9, air pressure suspension annulus, 10, radial direction keyway, 11, feather key, 12, axially position axle.
Embodiment
As shown in Fig. 1-3, a kind of hydraulic valve body axis hole honing three-dimensional air pressure suspension fixture, including bottom plate 3, air pressure hang
Over draft seat 4, positioning seat 5, pressing plate 7 and axially position axle 12, bottom plate 3 is rectangular, and there are chute 2, air pressure suspension bearing in the both sides of bottom plate 3
4 are arranged on bottom plate 3, and air pressure suspension annulus 9 is included in air pressure suspension bearing 4, and 9 ring cross sections of air pressure suspension circle are rectangular configurations,
Respectively there is a radial direction keyway 10 above and below of air pressure suspension annulus 9, and above and below radial direction keyway 10 staggers 90 degree of angles, radial direction key
Feather key 11 is installed, positioning seat 5 is arranged on air pressure suspension annulus 9 and do not contacted with air pressure suspension bearing 4, and air pressure suspends in groove 10
Annulus 9, air pressure suspension bearing 4 and positioning seat 5 are on same datum plane, and axially position axle 12 is arranged on positioning seat 5, axle
To locating shaft 12 top braces in the bottom surface of the pressing plate 7, pressing plate 7 is arranged on positioning seat 9 by bridge screw 8, and is locked
Tightly.
Certain air pressure is produced between air pressure suspension bearing 4 and air pressure suspension annulus 9, air pressure suspension annulus 9 is produced air pressure
Suspension can support honing fixture to float, and the gap very little of chute 11 of air pressure suspension bearing 4, form axial flying height, can be with
Air pressure suspension annulus 9 is slided along the key rails Two Dimensional Free in top and bottom radial direction keyway 10, make the part of positioning seat 5 and bottom plate 3
Air pressure suspended state in three-dimensional all-directional, honing reamer can be kept to enter honing reamer access aperture 6, air pressure in three-dimensional
Self-centering in suspension Honing process accuracy range.
Three-dimensional air pressure suspension honing fixture provided by the utility model, 1 vertical axial hole of hydraulic valve body can be carried out
Honing process, hydraulic valve body 1 can three-dimensional air pressure suspend, to compensate the change of honing setting accuracy, it is ensured that honing is cut with scissors
Hole accuracy reaches circularity 0.001mm, linearity 0.002mm and cylindricity 0.003mm, roughness 0.2Rz, and a whole set of fixture
Simple in construction, three-dimensional air pressure suspension is flexible, uses convenient disassembly.
