Description
Technical field
Field of optical device technology is the utility model is related to, more particularly, to a kind of auxiliary fixture for lenses polishing.
Background technology
Lens can be widely applied to the every field such as security protection, vehicle-mounted, digital camera, laser, optical instrument, with market not
Disconnected development, lens technologies are also increasingly widely used.Lens are according to made of the law of refraction of light, and it is by transparency material
（Such as glass, crystal）A kind of manufactured optical element.Lens are refracting telescopes, and its plane of refraction is by two spheres（One, sphere
Point）It is combined into, or by a sphere（Piece）And the transparent body that a plane is combined into, its imaging have reality
As also there is the virtual image.
Lenses polishing be a procedure of most critical in lens processing, it is necessary to remove the destruction layer of refining surfaces, reaching will
The surface roughness requirements asked, refine face type, reach the surface face type of customer requirement（Aperture and local error）, the plating of Bing Weihou roads
The processes such as film, gluing create conditions.
But when being polished under high speed pressure, face shape defect, surface roughness and aperture stability can be directly affected.Cause
In this polishing process, operating personnel need the technological parameter rule of thumb often adjusted, such as head pressure, the rocker amplitude of oscillation and pendulum
Angle etc., it is finally the qualitative adjustment by technological parameter, changes any point between arbitrarily instantaneously upper mould contacts surface with mirror disk
Pressure is distributed and relative linear velocity, with the surface quality obtained, so as to reach the surface face type of customer requirement（Aperture and part
Error need to meet the requirements of the customers）.
Existing lenses polishing auxiliary fixture is to be directed to be designed per a product specification, and interior loop material is usually wear-resisting
The polytetrafluoroethylene (PTFE) of damage, the outside dimension of tool is designed according to lens prescriptions（Such as 1.5mm is processed on the external diameter of normal product
Thickness), depth dimensions, radius of curvature value, but do such polishing, the face type stability of the radius of curvature value of its finished product is poor,
Defect rate is high, and often reprocesses, and virtually reduces efficiency, so increases the cost of labor of each product, will have a strong impact on that lens produce
The phase is handed in the delivery of product.
Utility model content
Technical problem to be solved in the utility model is：A kind of auxiliary fixture for lenses polishing is provided, realized steady
Surely the aperture of lens face type is polished, production efficiency is improved, reduces cost.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：One kind is provided and is used for lenses polishing
Auxiliary fixture, it is characterised in that including cup dolly, the cup dolly is made up of polytetrafluoroethylmaterial material；In the circle
Circular platform, and the big 25 ~ 30mm of radius of circular platform described in the radius ratio of the cup dolly are provided with the center of shape base；
4 identical flutings are uniformly provided with the cup dolly, the both ends of the fluting are outer with the cup dolly respectively
Connected in wall and the circular platform, the fluting wide 1mm, deep 10mm.
Wherein, polishing fluid is filled in the fluting.
The beneficial effects of the utility model are：Prior art is different from, the utility model passes through in cup dolly
Circular platform is set at the heart, for placing polished lens, and 4 flutings are uniformly arranged thereon, fluting both ends connect respectively
Connect on the outside of circular platform and cup dolly,.By the above-mentioned means, the utility model, which can be realized, amplifies polished eyeglass, realize
Stable polishing, reduces and manually reprocesses cost, improves production efficiency.
Brief description of the drawings
Fig. 1 is the surface structure schematic diagram for the auxiliary fixture that the utility model is used for lenses polishing；
Fig. 2 is the structural representation of circular platform in Fig. 1；
Fig. 3 is Section A-A structure sectional view in Fig. 2.
Embodiment
For detailed description technology contents of the present utility model, the objects and the effects, below in conjunction with embodiment and match somebody with somebody
Accompanying drawing is closed to be explained.
Fig. 1 ~ Fig. 3 is refer to, the utility model provides a kind of auxiliary fixture for lenses polishing, including cup dolly 1,
The cup dolly 1 is made up of polytetrafluoroethylmaterial material；Circular platform 2 is provided with the center of the cup dolly 1.It is and described
Big 25 ~ the 30mm of the radius of circular platform 2 described in the radius ratio of cup dolly 1；4 are uniformly provided with the cup dolly 1 completely
Identical fluting 3, i.e., 4 flutings 3 overall be in cross, it is described slot 3 both ends respectively with the outer wall of the cup dolly 1 and
Connect in the circular platform 2, the fluting 3 wide 1mm, deep 10mm, polishing fluid is filled in the fluting.
The beneficial effects of the utility model are：Prior art is different from, the utility model passes through in cup dolly
Circular platform is set at the heart, for placing polished lens, and 4 flutings are uniformly arranged thereon, fluting both ends connect respectively
Connect on the outside of circular platform and cup dolly,.By the above-mentioned means, the utility model, which can be realized, amplifies polished eyeglass, realize
Stable polishing, reduces and manually reprocesses cost, improves production efficiency.
For existing polished surface face type（Aperture and local error）It is unstable, it is described in the utility model polishing auxiliary
Tool material is polytetrafluoroethylene (PTFE)（It is wear-resistant）Material POM, tool external diameter is designed on the basis of existing product specification, such as just
25-30mm extension width is added in normal product specification, i.e., places polished eyeglass on middle circular platform 2, and at this
It is provided with cross recess in extension, deep 10mm, cross recess memory storage polishing fluid, can effectively prevent product temperature liter under high speed pressure
Height, the imagination of " dry pan " is caused, influence the performance of eyeglass and auxiliary fixture, it is bad etc. finish occur.Wherein, the utility model
Change the inner ring without using duralumin material of the prior art, all polytetrafluoroethylmaterial materials, anti-wear performance is good.When pressure thimble
After directly bearing against on tool, carry out repairing polished surface face type（Aperture and local error）, and be actually equivalent to mirror
Piece amplifies, and error range can be moved to fixture, error just is not present on lens, it is ensured that quality is qualified.
Material is all changed to polytetrafluoroethylene (PTFE) material by the utility model（It is wear-resistant）, lens surface face in polishing process
Type（Aperture and local error）It is caused bad, it can be avoided by the auxiliary fixture, ensure the stability of face type, and carried
The first-time qualification rate of high product.Can so greatly promote production efficiency, reduce reprocessing for product repeatability, reduce manually into
This.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalents made using the utility model specification and accompanying drawing content, or directly or indirectly it is used in the technology neck of correlation
Domain, similarly it is included in scope of patent protection of the present utility model.
