Description
Technical field
The invention belongs to field of optical detection, more particularly to a kind of sealing prism gauge for placing prism.
Background technology
Utilize surface sweep angle polarisation method GASP（Grazing Angle Surface Polarimetry）Measure tempered glass
During surface stress, its measuring principle is：, can be with parallel glass in the thin layer of near surface when light incides glass surface
A small distance is run in the direction on surface, if glass surface does not have stress, light is all-trans with that can be produced during critical angle incidence
Penetrate, i.e., light can be propagated along glass surface, and can be returned again with reflection at critical angle.If glass surface has stress, glass is incided
The total reflection light on glass surface can produce birefringence under the action of stressor layers, form that two beam polarization directions are orthogonal and propagation side
To different light beams, which is converted into bright fringes or dark fringe easy to identification by imaging unit, passes through calculating
Interference fringe information is so as to obtain corresponding glass surface stress value.Thus, answered using above-mentioned principle test tempering glass surface
During force information, it is necessary to glass to be detected is placed on refracting prisms, to ensure that testing result is reliable and stable, in detection process
It need to ensure that refracting prisms are fixed, it is more in practice that refracting prisms are fixed in prism platform, since stress mornitoring process needs
To dropwise addition REFRACTIVE LIQUID between glass to be detected and refracting prisms so that the two comes into full contact with so as to improve stress mornitoring precision, still
The REFRACTIVE LIQUID that existing prism platform easily causes to be added dropwise is slid to the detecting instrument of lower section by refracting prisms periphery, to scavenger
Difficulty is brought, or even corrosion phenomenon can be caused to detecting instrument.
The content of the invention
Present invention aim to address above-mentioned the deficiencies in the prior art, there is provided it is a kind of it is reasonable in design, will not be to detection
Instrument causes the easy sealing prism gauge of corrosion phenomenon, cleaning.
Technical solution is used by the present invention solves above-mentioned the deficiencies in the prior art：
One kind sealing prism gauge, including jig body, it is characterised in that the jig body, which is equipped with, can accommodate refraction
The prism mounting hole of prism, the geomery of the prism mounting hole is adapted with the geomery of the refracting prisms, described
Refracting prisms and the jig body close proximity.
Preferably, heretofore described jig body is equipped with suction hole, and the suction hole is distributed on the prism installation
The neighboring in hole, the jig body lower surface are equipped with the aspirating hole being adapted with the suction hole, the jig body upper table
Air intake passage is equipped between face and lower surface, the suction hole is connected with the aspirating hole by the air intake passage, the pumping
Stomata connects air extractor by exhaust pipe.By setting suction hole on prism gauge, controlled without being separately provided air-breathing again
Tool, not only simplifies stress detection device structure, is reduced in size, reduce manufacture cost, and can improve prism gauge
Stability.
Preferably, heretofore described suction hole is threaded hole.When glass size to be measured is less than the border of suction hole,
By that to bolt is screwed into suction hole, the suction hole that glass to be measured cannot cover can be blocked, it is therefore prevented that since glass cannot
Cover suction hole and vacuum can not be produced at glass and suction hole.
Preferably, aspirating hole of the present invention is equipped with two, and two aspirating holes are located at the two of prism mounting hole respectively
Side.Since jig body upper surface is equipped with multiple suction holes, two aspirating holes are equipped with lower surface can make to produce at suction hole
Stable gas pressure and equilibrium, be preferably bonded beneficial between glass to be measured and refracting prisms.
Preferably, jig body of the present invention is equipped with fastening thread hole, fastening thread hole by with fastening bolt
Cooperate, prism gauge of the present invention is fixed in glass strain detection device, improve the stability of stress detection device.
Preferably, heretofore described jig body is integrally formed, simple in structure, easy to process.
The invention has the advantages that since present invention sealing prism gauge includes jig body, in the jig body
Equipped with the prism mounting hole that can accommodate refracting prisms, the geomery of the prism mounting hole and the shape ruler of the refracting prisms
It is very little to be adapted, the refracting prisms and the jig body close proximity, thus during use prism gauge of the present invention, will need to only roll over
Penetrate prism to be placed in prism mounting hole, close proximity between refracting prisms and jig body, to folding in stress mornitoring work
Penetrate prism surface be added dropwise REFRACTIVE LIQUID when, avoid REFRACTIVE LIQUID slid by refracting prisms periphery to the detecting instrument of lower section, to
Cleaning brings bad phenomenon difficult, that corrosion can be even caused to detecting instrument, reasonable in design, easy to process, system
Make of low cost, have a vast market prospect.
