Description
Technical field
The present invention relates to fixture, particularly a kind of easy frock.
Background technology
As the manufacturing fast development of optics, and field of aerospace constantly carry to the demand of optical aspherical surface mirror
Height, the bottleneck that high-precision aspherical mirror machining runs into also become increasingly conspicuous.Although high-precision milling and grinding machine precision more and more higher, it adds
The medium, high frequency and sub-surface damage layer that work is brought unavoidably have influence on follow-up high accuracy polishing.How removal milling and grinding machine is invented
Caused medium, high frequency and subdamage layer are even more important, and the present invention not only can effectively improve aspherical roughness and sub-surface damage
Hinder layer, and medium, high frequency can be significantly improved.
The content of the invention
, not only can be effective it is an object of the invention to provide a kind of fast and convenient automatic grinding aspherical frock and method
Improve aspherical roughness and sub-surface damage layer, and medium-high frequency can be significantly improved.
The technical scheme is that：A kind of aspherical frock of fast and convenient automatic grinding, including connection two axles grinding
The omnipotent transfer of polishing machine, the omnipotent transfer include installed part and the bottom that top is connected with two axle polisher lappers
Seat；
The installed part bottom is convex spherical structure；The base is frustum cone structure, and the small circular portion of frustum cone structure is recessed ball
Structure, recessed spherical structure coordinate with convex ball for gap, form universal rotational connection；
Including abrasive disk, the abrasive disk is formed by nylon frock surface adhering to polyurethane；The abrasive disk with it is aspherical
The aspherical contact surface of mirror is shaped as aspherical best fit sphere；
The big circular portion of the frustum cone structure is fixedly mounted with abrasive disk.
Further, the polyurethane thickness is 1 ± 0.1mm.
The present invention also provides the Ginding process realized according to the aspherical frock of fast and convenient automatic grinding, and specific steps are such as
Under：The floor installation of omnipotent transfer on the abrasive disk with polyurethane, the installed part of omnipotent transfer is connected to
On the balance staff of two axle polisher lappers, aspherical mirror is placed on the rotating disk of two axle polisher lappers, in polyurethane surface plus W20
Diamond, abrasive disk with balance staff swing, aspherical mirror with two axle polisher lappers turntable rotation, due to omnipotent turn of increase
To device so that abrasive disk along aspherical normal machine, does not destroy existing face type all the time, is aspherical lapping schematic diagram,
By 2 hours or so time, surface roughness and sub-surface damage layer are effectively improved, and significantly improves what milling and grinding machine left
Medium, high frequency, reach the requirement before polishing.
Further, abrasive disk is all the time 1.5-2.5 hours along the aspherical normal machine time.
The beneficial effects of the invention are as follows：The inventive method, economical and practical, operating personnel can easily complete high request
Surface quality.
The polishing time is reduced, improves polishing precision.
Because polyurethane surface there are many holes, play and hold sand effect well, saved diamond dust, realize substantially certainly
Dynamicization is processed, and has saved human cost.
The method is not high to the skill set requirements of operator so that aspherical lapping is no longer highly difficult work, is especially suitable for grinding
Grind inexperienced operative employee.
Brief description of the drawings
Fig. 1 is omnipotent transfer；
Fig. 2 is aspherical lapping schematic diagram.
In figure：1 is omnipotent transfer, and 2 be abrasive disk, and 3 be aspherical mirror, and 4 be installed part, and 5 be base.
Embodiment
The present invention is described further below in conjunction with the accompanying drawings.
So that product material is fused quartz as an example, diameter 320mm aspherical mirrors 3, thickness 35mm, it is desirable to face type≤1/6WAVE.
According to technological requirement milling machining it is aspherical after grind again, drawn by processing early stage experience, with abrasive disk plus
W20# diamond dust is ground, and can improve roughness, reduces high frequency and intermediate frequency knife mark that sub-surface damage layer and milling and grinding machine leave, and not
Face type after destructible milling machining, herein before invention, the number of axle of Zeeko IRP600 seven is directly used after usual Raul's processing
Heavy caliber polishing machine is controlled, but effect is undesirable, it is difficult to remove the knife mark that milling and grinding machine leaves, particularly medium, high frequency.
By improving, as shown in figure 1, the frock that a kind of fast and convenient automatic grinding of design is aspherical, including connect two axles
The omnipotent transfer 1 of polisher lapper, omnipotent transfer 1 include the installed part 4 that top is connected with two axle polisher lappers
With base 5.The bottom of installed part 4 is convex spherical structure.Base 5 is frustum cone structure, and the small circular portion of frustum cone structure is recessed spherical structure, recessed
Spherical structure coordinates with convex ball for gap, forms universal rotational connection.Also include abrasive disk 2, abrasive disk 2 is glued by nylon frock surface
Knot 1mm polyurethane forms.The aspherical contact surface of abrasive disk 2 and aspherical mirror 3 is shaped as aspherical best fit sphere.Circle
The big circular portion of platform structure is fixedly mounted with abrasive disk 2.
It is during adhering to polyurethane, flat clear on nylon abrasive disk is clean, after disk to be ground is dried, bond 1mm thickness
Polyurethane, now as shown in Fig. 2 the floor installation of omnipotent transfer on the abrasive disk with polyurethane, omnipotent steering
The installed part of device is connected on the balance staff of two axle polisher lappers, and aspherical mirror is placed in the rotating disk of two axle polisher lappers
On, in polyurethane surface plus W20 diamonds, abrasive disk turns with balance staff swing, aspherical mirror with two axle polisher lappers
Disc spins, due to increasing omnipotent transfer so that abrasive disk along aspherical normal machine, does not destroy existing face all the time
Type, such as Fig. 2, it is aspherical lapping schematic diagram, by 2 hours or so time, is effectively improved surface roughness and sub-surface damage
Layer, and the medium, high frequency that milling and grinding machine leaves is significantly improved, reach the requirement before polishing.
By being made comparisons with the method before improvement, advantage is as follows：
1. reducing the polishing time, polishing precision is improved.
2. because polyurethane surface there are many holes, play and hold sand effect well, saved diamond dust, realized substantially
Automation processing, has saved human cost.
3. the method is not high to the skill set requirements of operator so that aspherical lapping is no longer highly difficult work, is especially suitable for
Grind inexperienced operative employee.
It the above is only the preferred embodiment of the present invention, it is noted that come for those skilled in the art
Say, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should be regarded as
Protection scope of the present invention.
