Abstract
The utility model discloses a measuring device for the granularity of diamond gritsm, which is characterized in that the measuring device for the granularity of diamond grits comprises a stereoscopic microscope, a CCD camera, an image collecting card and a computer system, wherein, a photographing interface is arranged on the stereoscopic microscope; the CCD camera is connected with the stereoscopic microscope through the photographing interface, and is connected with the image collecting card; a PCI interface is arranged on the computer system; the image collecting card is connected with the computer system through the PCI interface. The utility model has the advantages that the measuring device can work out the average size of the diamond grits and the size of each diamond grit, so the granularity size distribution of the diamond grits is obtained; the measuring device has the characteristics of simple operation, no need of manual computation, clean working environment and no noise in the measuring process.
Description
Technical field
The utility model relates to a kind of measurement mechanism, especially relates to a kind of measurement mechanism of diamond abrasive grain granularity.
Background technology
Adamas is a kind of superhard material commonly used, and it has good physical properties such as high rigidity, high strength, so diamond abrasive grain becomes the important component part of making all kinds of diamond tool goods.Usually, before diamond tool is made, select suitable diamond abrasive grain granularity (granularity is represented the big or small degree of abrasive particle, the diameter dimension of reflection diamond abrasive grain) earlier, and the instrument of having relatively high expectations for some manufacturing accuracy is relatively stricter to the coherence request of diamond abrasive grain granularity.At present, mainly detect the granularity of diamond abrasive grain with sieve method, the used major equipment of sieve method is sieve shaker and test sieve, through screening process, just the granularity of diamond abrasive grain can be determined, but, the scope of diamond abrasive grain granularity can only be detected because existing screening proving installation is subjected to the restriction of test sieve mesh size, the average-size of diamond abrasive grain be can not detect, the size of each abrasive particle and the Size Distribution state of diamond abrasive grain more can not be detected.In addition, the test sieve in the screening plant is through repeatedly using, and sieve screen apertures is blocked easily, influences screening effect.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of average-size that can detect diamond abrasive grain, the measurement mechanism of diamond abrasive grain granularity that also can detect the size of each abrasive particle and the Size Distribution of granularity can be provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of measurement mechanism of diamond abrasive grain granularity, it comprises stereomicroscope, ccd video camera, image pick-up card and computer system, described stereomicroscope is provided with the photography interface, described ccd video camera is connected with described stereomicroscope by described photography interface, described ccd video camera is connected with described image pick-up card, described computer system is provided with pci interface, and described image pick-up card is connected with described computer system by described pci interface.
Compared with prior art, the utility model has the advantages that because this measurement mechanism comprises stereomicroscope, ccd video camera, image pick-up card and computer system, when measuring, it obtains the optical microscopic image of diamond abrasive grain earlier by stereomicroscope, convert digital picture to through ccd video camera and image pick-up card then, be input to computer system, the digital picture that on computer screen, shows diamond abrasive grain, also can calculate the average-size of diamond abrasive grain and the size of each abrasive particle by the software in the computer system then, thereby also can obtain the size distribution of diamond abrasive grain; And this device is simple to operate, need not artificial calculating, working environment cleaning, testing process noiseless.

Fig. 1 is the connection diagram of each ingredient of the present utility model;
Fig. 2 is the size-grade distribution constitutional diagram by the available diamond abrasive grain of device of the present utility model.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of measurement mechanism of diamond abrasive grain granularity, it comprises stereomicroscope 1, ccd video camera 2, image pick-up card 3 and computer system 4, stereomicroscope 1 is provided with photography interface (not shown), ccd video camera 2 is connected with stereomicroscope 1 by the photography interface, ccd video camera 2 is connected with image pick-up card 3, and computer system 4 is provided with the pci interface (not shown), and image pick-up card 3 is connected with computer system 4 by pci interface.
The concrete operations step of utilizing above-mentioned measurement mechanism to measure the diamond abrasive grain granularity is:
(1), with diamond abrasive grain to be measured evenly tiling be placed on the sample stage of stereomicroscope 1, and make between each diamond abrasive grain and leave minim gap;
(2), the enlargement factor that stereomicroscope 1 is set is 20;
(3), move known Debris Image granularity identification software on the computer system 4, the enlargement factor of input stereomicroscope 1;
(4), adjust the object lens position of stereomicroscope 1, make the adamas image that shows on the computer screen the most clear;
(5), the sample stage of trimming body stereomicroscope 1, select the adamas image that shows on the computer screen, as the image of wear particle size identification;
(6), application Debris Image granularity identification software calculates the average-size of diamond abrasive grain in the image automatically, and draws the size-grade distribution constitutional diagram (as accompanying drawing 2) of diamond abrasive grain in the image.
