Description
Technical field
A kind of grinding and polishing device is the utility model is related to, is applied in the grinding and polishing field of eyeglass.
Background technology
Multi-disc processing is a kind of conventional mode of production of optics cold working.With the market price of current eyeglass cold working fierceness
Lattice compete, and manufacturing enterprise is lifting processing efficiency, eyeglass is processed using grinding and polishing device more, existing grinding and polishing
Device is adhesive with the polishing of grinding and polishing layer (component is polyurethane) including lenz disc and the bottom surface that be located on lenz disc top surface
Mould, wherein the top surface of the lenz disc for convex surface and once can clamping fix multi-disc (be usually 20-200 pieces) eyeglass, the throwing
The bottom surface of optical mode and the convex shape of lenz disc top surface are adapted, and eyeglass is fixed on lenz disc top surface during processing, and polishing is embossed in
The lens surface is in contact with it grinding and polishing layer so as to be ground polishing to it.
The grinding and polishing process is carried out under the processing conditions of high pressure and high speed, lens surface and polyurethane material
The friction of grinding and polishing layer when temperature can reach more than 100 degree.In polishing process, it is necessary in the (processing of the surface of eyeglass
Face) on pour polishing fluid.Polishing fluid is formed by water and polishing powder allotment.The effect of polishing fluid is mainly played eyeglass hydrolysis, is ground
Grinding and polishing light and three effects for reducing lens surface temperature.The process of lens grinding polishing is mainly water, polishing powder, grinding throwing
The result of the chemical action between eyeglass such as photosphere.Because the main component of eyeglass is exactly silica, work of its surface in water
With unboiled water solution is issued, silicon state silicic acid layer is formed.Under normal circumstances, collodial silica layer can protect the surface of eyeglass, slow down significantly
Erosive velocity, but under the action of grinding and polishing layer and polishing powder, which is scraped off, and exposes the new surface of eyeglass,
The new surface of rear lens hydrolyze again and produce new silicon state silicic acid layer, new silicon state silicic acid layer is again in grinding and polishing layer and polishing powder
Under the action of scraped off, and so on circulate, to complete grinding and polishing process.But in process, when polishing fluid pours
Because polished die runs at high speed, the centrifugal force of generation causes polishing fluid to be difficult the core for touching polished die, thus easily production
Situations such as raw polished die fever, the eyeglass of lenz disc center clamping anhydrous grinding, causes lens product quality unqualified.
Therefore, although its processing efficiency is higher, generate heat to evade above-mentioned polished die, the eyeglass of lenz disc center clamping
Reduction processed rotating speed or reduced tonnage (i.e. its heat dissipation is worse), it is necessary to extend process time situations such as anhydrous grinding, so that
Cause multi-disc process efficiency have a greatly reduced quality, be lost at the same time multi-disc process raising efficiency effect.
Therefore provide it is a kind of can so that avoid polished die to generate heat during machining eyeglass, on whole lenz disc clamping eyeglass
Can be adequately exposed to polishing fluid avoid anhydrous grinding, can effective guarantee multi-disc processing efficiency and quality grinding and polishing device oneself
As when business urgently.
Utility model content
Although in order to overcome existing grinding and polishing device processing efficiency higher, due to polished die run at high speed generation from
The polishing fluid that mental and physical efforts cause to pour is difficult the core for touching polished die, is easy to cause polished die fever, lenz disc center
Situations such as eyeglass of clamping anhydrous grinding, to avoid case above, it is necessary to extend process time, reduce processing rotating speed or reduce plus
Work pressure, the shortcomings that causing multi-disc processing efficiency to reduce, the utility model provides a kind of grinding and polishing device, and having can be in eyeglass
Polished die fever is avoided in process, ensures that the eyeglass of clamping on whole lenz disc can be adequately exposed to polishing fluid so as to keep away
The advantages of exempting from anhydrous grinding, energy effective guarantee multi-disc processing efficiency and quality.
The technical solution of the utility model is as follows：
A kind of grinding and polishing device, including can be with the eyeglass for being used for clamping and living eyeglass of main axis on main shaft
Disk, be located on lenz disc top surface with lenz disc coordinate eyeglass is ground polishing polished die, be close to be arranged on polished die
On bottom surface be used for eyeglass is ground polishing polyurethane grinding and polishing layer and be vertically pressed on polished die top center
For fixing the last item of both polished die and lenz disc relative position, the top surface of the lenz disc is convex surface, the polished die bottom
The radius of curvature in face is identical with the radius of curvature of lenz disc top surface and both shapes are adapted.The polished die is equipped with perforation and throws
Multiple limbers of optical mode upper and lower surface, correspond on polyurethane grinding and polishing layer and the poly- ammonia of perforation are additionally provided with the position of each limbers
Multiple holes of ester grinding and polishing layer upper and lower surface.
Be different from it is existing in polishing processing, on the surface of eyeglass (machined surface) directly pour polishing fluid, due to
Centrifugal force effect polishing fluid, which can not reach, causes polished die fever, the anhydrous grinding of eyeglass on the eyeglass of lenz disc face center position
The problems such as the shortcomings that.The polished die of the grinding and polishing device of this application is provided with limbers, and during machining lens, polishing fluid directly pours
At the top of polished die, it can not only directly cool down polished die, and can be flowed directly to by limbers and be folded in mirror

Between the angle that is formed, RypFor blade radius.
The above-mentioned restriction to polyurethane grinding and polishing layer blade is so that heat dissipation, polishing efficiency and the performance of grinding and polishing device
Get a promotion.
The multiple blade is the big blades such as 6-8 pieces.
Blade quantity can increase stock removal rate more, but excessively the contact surface of polyurethane grinding and polishing layer and eyeglass subtracts quantity afterwards
Small and influence grinding polishing effect, thus it is the most suitable using the big blade such as 6-8 pieces, can be in stock removal rate and grinding polishing effect
Between keep balance.
Described adhesive layer is three keys, 1521 synthetic rubber layer.
Polyurethane grinding and polishing layer and polished die, polyurethane after natural temperature drying are bonded using three keys, 1521 synthetic rubber
The entirety that grinding and polishing layer is solidified into polished die, does not influence the original pliability of polyurethane grinding and polishing layer but, ensures
Grinding polishing effect.
The polyurethane grinding and polishing layer bottom surface is equipped with least 1 groove of perforation polyurethane grinding and polishing layer central point,
And the both ends of every groove all extend to the outer edge of polyurethane grinding and polishing layer.
The setting of the groove further improves the efficiency of polishing fluid discharge, improves thermal diffusivity.
The groove is 2 and is mutually perpendicular to.The width of every groove is 0.5-1.5mm.
Above-mentioned preferable groove can obtain optimal grinding polishing effect while thermal diffusivity is ensured.The width can
