Description
Technical field
The present invention relates to a kind of technique for grinding, particularly a kind of optics uniform grinding method.
Background technology
It is to influence final product quality extremely by the uniformity of optics polishing and planarization during optics polishes
Important parameter is closed, when existing erratic star wheel polishes in polishing machine, because optics can together rotate with erratic star wheel, therefore
The angle that optics is in periphery can pass through longer abrasion path, so as to which same optics flatness after grinding occur
Situation about differing i.e. turned-down edge, in this case the uniformity of product can not also ensure.
The content of the invention
The technical problems to be solved by the invention are to provide and a kind of can made to polish by the method for optics uniform grinding
The abrasion path that optics each several part is passed through in journey is essentially identical.
Technical scheme is used by the present invention solves above-mentioned technical problem：
A kind of erratic star wheel of uniform grinding, circular polishing hole is offered inside the erratic star wheel, and the polishing hole is being polished
During around erratic star wheel central rotation, be provided with processing cavity in the polishing hole, the processing cavity is rotatably connected erratic star wheel, institute
State the coefficient of friction that the coefficient of friction between processing cavity and erratic star wheel is less than between processing cavity and workpiece to be added.
Further, annular raceway is offered in the erratic star wheel, ball is provided with the raceway, the processing cavity connects
Connect ball and do not contacted with erratic star wheel.
Further, connected between the processing cavity and ball by elastic component.
Further, the distance between the processing cavity and ball is equal to the natural length of elastic component.
Preferably, the quantity of the ball is three or four and spaced set.
Preferably, the erratic star wheel contacts connection with processing cavity, lubricating layer is provided between the two.
Method is used by the present invention solves above-mentioned technical problem：
A kind of method of optics uniform grinding, its step are：
S1, erratic star wheel is put into polishing machine；
S2, optics is put into processing cavity, the processing cavity is located in the polishing hole of erratic star wheel, and processing cavity relative can be beaten
Grinding out freely rotates；
S3, start to polish, erratic star wheel rotates with polishing machine driving wheel and has rotational velocity w1, processing cavity with erratic star wheel and
Optics rotates and has rotational velocity w2, the w1 ≠ w2.
Further, the w1<w2.
Preferably, erratic star wheel offers annular raceway in the step S2, ball is provided with the raceway, it is described to add
Work chamber connects ball and not contacted with erratic star wheel, is connected between the processing cavity and ball by elastic component；Add in the step S3
The center of the relative erratic star wheel of work chamber meeting shifts.
The present invention compared with the existing technology has advantages below and effect：Due to setting rotatable add inside erratic star wheel
Work chamber, optics produce change relative to the rotational velocity of erratic star wheel, so as to which optics is relative to the travel path of mill
Changing always, eliminating the phenomenon of turned-down edge.The cooperation requirement of processing cavity and erratic star wheel is reduced by the connection design of ball,
The addition of elastic component further reduces cooperation difficulty, and processing cavity is designed to the non-circular processing beneficial to processing cavity,
Also due to unbalance stress makes processing cavity be shifted with respect to the center of erratic star wheel in bruting process, so as to further change light
Learn the abrasion path of device.Simultaneously by selecting suitable elastic component and ball quantity, ensure that between ball and erratic star wheel compared with
Small coefficient of friction, and in processing stability will not make certain elastic component stress excessive well so as to increase ball and erratic star wheel it
Between frictional force.The cooperation difficulty of processing cavity and erratic star wheel can also be reduced by way of lubricating layer is set in addition.

Embodiment
With reference to embodiment, the present invention is described in further detail, following examples be explanation of the invention and
The invention is not limited in following examples.
Embodiment 1：
As shown in figure 1, the present embodiment is made up of erratic star wheel 1 and processing cavity 2, polishing hole 11, polishing are offered on erratic star wheel 1
Hole 11 is in bruting process around the central rotation of erratic star wheel 1.Fig. 2 is the cooperation schematic diagram of erratic star wheel 1 and processing cavity 2, wherein wandering star
The annular raceway coordinated with ball 3 is offered on wheel 1, the other end of ball 3 is arranged in the notch that processing cavity 2 opens up (same
Annular raceway can also be arranged to), and not in contact with offering rectangle work in processing cavity 2 between erratic star wheel 1 and processing cavity 2
Position 4, when contemporary workpiece is put into station polishing, erratic star wheel 1 rotates with the driving gear of polishing machine, due to for workpiece and mill
Between exist and prevent frictional force from workpiece to the rotation direction of erratic star wheel 1 that rotated for, and the frictional force between processing cavity 2 and erratic star wheel 1
It is less than above-mentioned frictional force again, so it is slower relative to the rotational velocity of erratic star wheel 1 for workpiece, send out the abrasion path at each position
Changing.
Specifically procedure of processing is：
S1, erratic star wheel is put into polishing machine；
S2, optics is put into processing cavity, the processing cavity is located in the polishing hole of erratic star wheel, and processing cavity relative can be beaten
Grinding out freely rotates；
S3, start to polish, erratic star wheel rotates with polishing machine driving wheel and has rotational velocity w1, processing cavity with erratic star wheel and
Optics rotates and has rotational velocity w2, due to lapping apparatus and for the frictional force that acting in opposition between workpiece be present,
So that w1<w2.
Embodiment 2：
As described in Figure 3, the present embodiment is substantially the same manner as Example 1, and difference is to pass through elasticity between processing cavity 2 and ball 3
Part 31 connects, and wherein the natural length of elastic component 31 is equal to interval between processing cavity 2 and ball 3, so as to reduce processing cavity 2 with
Cooperation requirement between ball 3.When starting polishing, because unbalance stress makes processing cavity be shifted with respect to the center of erratic star wheel,
So that shifted for workpiece in the position of different parts so as to be ground on different paths.
Embodiment 3：
As shown in figure 1, erratic star wheel 1 directly contacts with processing cavity 2, lubricating layer is provided between the two, and lubricating layer can be alcohol
Acid resin, epoxy resin or acrylic resin, a little less than 5% metal oxide can also be added in above material to increase
Add wearability.
