Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1-2, many annular self adaptation grinding head for polishing of the present invention, including flange shaft 1, fastening bolt
2, multi-ring rigid basement 3, flexible ring 4 and buffing ring 5.Wherein, flange shaft 1 is not particularly limited, and is
The common mechanical structure being connected with main shaft of numerical control machine tool in this area, the top of flange shaft 1 and Digit Control Machine Tool master
Axle connects, and is fixed on Digit Control Machine Tool by many annular self adaptation grinding head for polishing, the concrete size of flange shaft 1 with
Machine tool chief axis matches.Multi-ring rigid basement 3 generally disc structure, top is provided with groove, the chi of groove
Very little and flange shaft 1 bottom coordinates, and the bottom of flange shaft 1 is fixed on multi-ring rigidity base by fastening bolt 2
The top at the end 3, makes flange shaft 1 can be synchronized with the movement with multi-ring rigid basement 3, the number of fastening bolt 2
Generally 3-6；The bottom of multi-ring rigid basement 3 be provided with have phase concentric and according to radius from small to large,
The multiple round ring boss being arranged in order from inside to outside, the width of the round ring boss of different radii can be identical
Can also be different, the spacing of the most adjacent two round ring boss can be the same or different, the most all circles
The bottom surface of annular boss has identical radius of curvature；All round ring boss can be with multi-ring rigid basement 3
Integrated molding；The number of round ring boss determines according to actual application；The material of multi-ring rigid basement 3 is
Metal material, such as duralumin, hard alumin ium alloy or rustless steel.Flexible ring 4 by have phase concentric and according to radius from little to
The multiple annulus composition being arranged in order greatly, from inside to outside, the preferably bottom surface of all annulus of flexible ring 4 has
Identical radius of curvature, the top of flexible ring 4 is fixed on the bottom of round ring boss, can be fixed on all
On round ring boss, it is also possible to be fixed on partial circle shape boss, concrete foundation round ring boss and flexibility
The annulus number of ring 4 determines, when round ring boss is identical with flexible ring 4 number, and flexible ring 4 is fixed on institute
Have on round ring boss, when the annulus number of flexible ring 4 is less than the number of round ring boss, and flexible ring 4 is solid
It is scheduled on partial circle shape boss, preferably multiple annulus of flexible ring 4 and multiple round ring boss one_to_one corresponding,
And size coupling, i.e. one round ring boss is fixed the annulus of a flexible ring 4 coordinated with its radius,
All annulus of flexible ring 4 are separately fixed on corresponding round ring boss, and fixed form typically uses
It is adhesively fixed；Flexible ring 4 is flexible material, generally macromolecular material, such as rubber or sponge.Buffing ring 5
By there is phase concentric and multiple annulus of being arranged in order from small to large, from inside to outside according to radius form, throw
The bottom surface of all annulus of the ring of light 5 has identical radius of curvature, and for contacting with surface of the work, polishing
The top of ring 5 is fixed on multiple annulus and the flexible ring more than 4 of the bottom of flexible ring 4, preferably buffing ring 5
Individual annulus one_to_one corresponding, and size matches, i.e. fix on the annulus of a flexible ring 4 one with its radius
The annulus of the buffing ring 5 coordinated, all annulus of buffing ring 5 are separately fixed at corresponding flexible ring 4
Annulus on, fixed form typically uses and is adhesively fixed；Flexible ring 4 and buffing ring 5 produce flexible change jointly
Shape, it is ensured that buffing ring 5 mates with aspherical surface shape；The material of buffing ring 5 is macromolecular material, as
