By employing the automatic glass stress detector, related information is provided through the image acquired by a camera for brightness of a measuring area, a rotation angle is automatically read through internal coding of the hand-operated rotation analyzer, so artificial measuring errors can be eliminated, moreover, a photosensitive color method of the automatic glass stress detector is employed, so stress existence and a stress distribution state can be easily observed, and detection precision is high.
Description
Technical field
The utility model relates to a kind of stress detection device, particularly a kind of automatic glass tension gauge.
Background technology
For traditional employing penalty method, carry out the stress ga(u)ge of glass detection, measurement result can be subject to the impact of operator self judgement, operating personnel are different, measurement data also can be variant, because the brightness of measured zone and reading in penalty method of analyzer angle are all with the naked eye observed, the error ratio that the data that it reads exist is larger, and therefore artificial measurement numerical result is accurate not, can not meet the needs of experiment test.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of automatic glass tension gauge of high-acruracy survey.
The utility model for the technical scheme that solves its technical matters and adopt is: a kind of automatic glass tension gauge, comprise polariscope, analyzer and detection eyepiece, described polariscope is arranged on the upper surface of base, directly over base, be also provided with a brace table, described analyzer can be arranged on brace table by manual rotation, detect the adjustable brace table top that is installed on of eyepiece, and the brace table being positioned under detection eyepiece is provided with a viewport, described detection eyepiece is adjustable focus eyepiece, the end of described detection eyepiece is installed an image-taking device, described image-taking device connects a processor for the treatment of image by data line.
As further improvement of the utility model, described image-taking device is a USB camera.
As further improvement of the utility model, on described brace table, be also provided with a proof stress instrument and adopt penalty method or sensitive color method to detect the selection lever of analyzing.
The beneficial effects of the utility model are: adopt after this tension gauge, the brightness of measured zone is to provide relevant information by camera gained image, and the anglec of rotation is also read automatically by the coding of the analyzer inside of manual rotation, therefore, the error in the time of can eliminating artificial measurement; And, adopt the sensitization color method in this instrument can easily observe stress existence and distribution situation, and the precision detecting is high.

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 shows a kind of embodiment of a kind of automatic glass tension gauge of the utility model, comprise polariscope 1, analyzer 2 and detection eyepiece 3, described polariscope 1 is arranged on the upper surface of base 4, directly over base 4, be also provided with a brace table 5, described analyzer 2 can be arranged on brace table 5 by manual rotation, detect adjustable brace table 5 tops that are installed on of eyepiece 3, described detection eyepiece 3 is adjustable focus eyepiece, the end of described detection eyepiece 3 is installed an image-taking device 6, described image-taking device 6 connects a processor 7 for the treatment of image by data line, described image-taking device 6 is a USB camera, on described brace table 5, being also provided with a proof stress instrument adopts penalty method or sensitive color method to detect the selection lever 8 of analyzing.
Sample is placed on polariscope, and bottom can be sent linearly polarized photon and be impinged upon on sample, and when sample contains stress, due to phase differential, linearly polarized photon can be converted into elliptically polarized light.On polariscope, there are two kinds of different phase differential wave plates, can switch by lever.Wherein for a penalty method, another kind of for sensitive color method.The optic axis direction of these two kinds different phase differential wave plates is preformed.
When selecting penalty method, can will change once again linearly polarized photon into because sample interior stress changes from linearly polarized photon the elliptically polarized light coming, because polarization angle now depends on the ellipticity of elliptic polarization, if can make brightness of image reach minimum value to a certain angle by pivot analysis device, light delay and stress value can automatically be calculated and are presented on computer monitor by the appended software of computer.
When selecting sensitive color method, the phase differential of sample can show with naked eyes visible wavelengths band.The whole visual field can be revealed as aubergine, and this color is called " sensitization look ".If sample has stress, color sample can be shown in green, blueness, and crocus, yellow or other colors, therefore can see the distribution of stress, and distinguish tension stress direction and compressive stress direction.
Appended software can store images and much information, such as picture and result of calculation etc.Equally also can read and show this type of data.Same, this software can change measurement result layout, reads the operations such as metrical information and printing.Can also data independently be edited and be preserved with csv form, can in EXCEL, carry out data edition.
