Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
Fig. 1-2 shows a kind of embodiment of a kind of Portable glass surface stress of the utility model meter, comprise instrument body 1 and base 2, the base of described instrument body 1 inside is provided with and irradiates minute surface 3 and exit minute surface 4, irradiate minute surface 3 and exit and between minute surface 4, be provided with measuring prism 5, described irradiation minute surface 3 and exit minute surface 4 adjustable-angles and be arranged on base 2, on instrument body 1 directly over irradiation minute surface 3, fixedly mount a generating laser 6, exit on the instrument body 1 directly over minute surface 4 eye lens 7 are installed, the detachable quartz wedge 8 of installing in lower end of described eye lens 7, instrument body 1 is stretched out in described eye lens 7 upper ends, and instrument body 1 upper surface that stretch out eye lens 7 upper ends is provided with angle index 9, the side of described instrument body 1 is provided with to connect respectively and regulates incident angle regulator 10 and the angle of outlet regulator 11 that irradiates minute surface 3 and exit minute surface 4, and in instrument body 1, be also provided with the chock regulator 15 of a quartz wedge 8, the periphery of described base 2 is provided with some height adjusters 12, the setting nut that height adjuster 12 is inserted base, described instrument body 1 opposite side is also provided with a hand holding handle 13, on described base 1, be fixed with a battery case 14, battery case 14 connects generating lasers 6 provides power supply for generating laser.
But the measuring method of above-described embodiment is as follows: in the air surface of glass, splash into one and have refractive index more higher than glass lower than the volatile liquid of measuring prism, then glass is placed on securely to measuring prism 5 tops, by incident angle regulator 10 and angle of outlet regulator 11, adjust the angle of irradiating border faces and exiting minute surface until the tortuous interference fringe penetrating on light is clearly apparent in the visual field of eye lens 7, on the incident angle regulator 10 of instrument body 1 one sides and angle of outlet regulator 11, determine the angle of irradiating minute surface 3 and exiting minute surface 4, rotation eye lens 7 are until the oblique interference fringe (parallel stripes) that measured sample surface stress on glass produces is parallel with two datum lines of display centre, can adjust by movement the further quartz wedge of adjusting of chock regulator 15 of eye lens 7 lower ends, make oblique interference fringe parallel more approaching with two datum lines of display centre, now, the angle Φ of interference fringe can read out from angle index 9, stress value adopts following formula to calculate:
Δ n=Δ R/Δ L=tan Φ and F=C Δ n/KC, F=surface stress (MPa), C=device sensitivity constant, Δ n=optical path difference (nanometer/centimetre), KC=photoelastic constant ((nanometer/centimetre)/MPa).
If interference fringe is tilted to the right, (in the same figure) shows it is compression stress, when striped is tilted to the left, shows it is tension stress, if the angle on the angle index reading is greater than 70 °, possible error degree obviously increases, and just should use muting sensitivity measuring equipment.
