Abstract
The utility model provides a kind of fixture of optics cold processing control lens center thickness, including lower clamp body, and lower clamp body is used to support lens to be processed, further includes upper fixture body, upper fixture body is for installing fine grinding mold；Upper fixture body includes pedestal interconnected and side circle, and the pedestal is cylindrical body, and side circle is annular solid, and stylus jack is equipped at the upper surface center of pedestal, and the inner peripheral wall bottom of side circle is equipped with the locating platform of annular.The fixture of this programme is during classic polishing processes process positive and negative meniscus lens, it is combined with existing uniaxial polishing machine, original technique upper disk disadvantage in center thickness control when processing this two kinds of lens is eliminated, saving positive and negative meniscus lens is measuring center thickness lacquer disk(-sc) again and again, lower wall time.It during processing can be according to operation reality loading, unloading at any time to realize the accurate control to lens center thickness.
Description
Technical field
The utility model relates to a kind of fixtures of optics cold processing control lens center thickness, belong to machining technique neck
Domain.
Background technique
With the extensive use of optical element various industries at home, the requirement to the positive and negative meniscus lens of optics is increasingly
Strictly, most of positive and negative meniscus lens has the characteristics that center thickness requirement is stringent, the thick difference in side is difficult to control, required precision is high,
Difficult point part or important Parts generally in optical system.
Center thickness tolerance is only between ± 0.01 ~ ± 0.03 in process for positive and negative meniscus lens, and due to Gu
Allusion quotation polishing mostly uses sealing wax lacquer disk(-sc), and the control of center thickness can only lean on operator's empirical estimating during fine grinding, or
It is measured according to fine grinding time lower wall.Operator's empirical estimating is made a discount greatly in accuracy, and lower wall measurement expends
Time, once not reaching precision prescribed also needs upper disk again, so original center reference is also needed by destroying
Again benchmark is looked for, the probability that positive and negative meniscus lens is scrapped since center is overproof is increased.The positive and negative bent moon of 50% ~ 70% high-precision
Lens scrap be as center it is overproof caused by, and the chance done over again is lost once overproof.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of folder of optics cold processing control lens center thickness
Tool, specific technical solution is:
A kind of fixture of optics cold processing control lens center thickness, including lower clamp body, lower clamp body be used to support to
Lens working further includes upper fixture body, and upper fixture body is for installing fine grinding mold；Upper fixture body include pedestal interconnected and
Side circle, the pedestal are cylindrical body, and side circle is annular solid, and stylus jack, the inner circle of side circle are equipped at the upper surface center of pedestal
Peripheral wall bottom is equipped with the locating platform of annular.
Further, the pedestal and side circle are structure as a whole.
Further, the pedestal and side circle are nylon rod material.
The beneficial point of the utility model is: compared with prior art, the utility model structure is simple, uses and the side of adjustment
Just, low in cost.Using the expansion performance of nylon rod material itself, reduce the extruding to positive and negative meniscus lens, and saturating
Mirror during refining convenient loading, unloading at any time it is same, it can be achieved that the real time monitoring to positive and negative meniscus lens center thickness measures
Lens are again during clamping convenient for the accurate center and orientation for determining part rapidly, when can greatly reduce upper disk centering and preparing
Between, use scope is wide, and it is easy to operate, therefore there is good economy and replicability.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention without any creative labor, may be used also for those of ordinary skill in the art
To obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, any modification, equivalent replacement, improvement and so on should be included in the utility model
Within protection scope.
As shown in Figure 1, a kind of fixture of optics cold processing control lens center thickness, including lower clamp body 6, lower clamp body
6 are used to support lens 7 to be processed, further include upper fixture body, upper fixture body is for installing fine grinding mold 5；Upper fixture body includes phase
The pedestal 1 to connect and side circle 2, the pedestal 1 are cylindrical body, and side circle 2 is annular solid, are equipped at the upper surface center of pedestal 1
The inner peripheral wall bottom of stylus jack 4, side circle 2 is equipped with the locating platform 3 of annular.The pedestal 1 and side circle 2 are structure as a whole.
The pedestal 1 and side circle 2 are nylon rod material.
The setting of locating platform 3 is inside side circle 2, the direct machine-shaping in process side circle 2 by lathe；The side circle 2 is set
It sets in 1 border of pedestal, side circle 2 is handed over by lathe simultaneously with pedestal 1；The stylus jack 4 is arranged on 1 top of pedestal.Make
Used time first selects jig bore according to processing part formal parameter, and what all External Shape parameters were close can be on the inside of fixture
It posts medical proof fabric to be reinforced, fixture and part is covered together then and start to process on accurate grinding mould, during processing
It can be according to operation reality loading, unloading at any time to realize the accurate control to lens center thickness.
The fixture can be widely applied to all high, precision and frontiers such as communication, information processing, material processing, medical treatment, agricultural, military affairs
In the process of accurate positive and negative meniscus lens.Fixture is and existing during classic polishing processes process positive and negative meniscus lens
The uniaxial polishing machine having combines, and eliminates original technique and goes up disk disadvantage in center thickness control when processing this two kinds of lens,
Saving positive and negative meniscus lens is measuring center thickness lacquer disk(-sc) again and again, lower wall time.With positioning accuracy height, add
The advantages that work is high-efficient and quality is stablized, the raising to the quality and mass production capabilities of part produces sizable promotion
Effect, positive and negative meniscus lens processing especially stringent to center thickness requirement, that the thick poor precision prescribed in side is high better reflect this
The superiority of fixture has promotional value.
