Abstract
The utility model relates to an apparatus which can measure the flat shape and the size of the measured object. An illuminating source and a collimator objective are arranged in the transmitting illuminant chassis and at the one side of the measured object. A light receiving chassis at the other side of the measured object is provided with a complete optical measuring system composed of an image-forming objective lens, a focusing optical grating and an area array CCD. The CCD converts the image into the electrical signal and transports the electrical signal into the computer for treatment, obtaining the flat shape and size of the measured object on the display.
Description
Affiliated technical field
The utility model belongs to measuring instrument, is the flat shape and the size of testee are carried out measurement mechanism.
Background technology
Measure for the flat shape of object and the measurers such as measurement employing slide calliper rule of size at present, perhaps produce surely that directional light projects to testee on the figure paper plane, compare by people's eyes with the figure on the drawing with light source and collimator objective.Above method exists measuring accuracy low, and automaticity is low, and measurement result can not be preserved inquiry.
Summary of the invention
The purpose of this utility model provides a kind ofly can watch the measurement mechanism of measurement pattern and data to the flat shape of testee and size by area array CCD, computing machine on the display of computing machine.
The technical scheme that the utility model technical solution problem is taked is the side at testee, by support light source and collimator objective, dustproof glass is installed in the transmitting illuminant cabinet.Image-forming objective lens, focus light hurdle, area array CCD, dustproof glass are installed in the reception ray machine case of testee opposite side, constitute a complete optical measuring system.CCD becomes electric signal to deliver to computing machine image transitions to handle, obtain testee flat shape and size on display.
The beneficial effects of the utility model are, have overcome the error that artificial eyesight difference is brought, and have improved measuring accuracy, can preserve inquiry to measurement result.
Below in conjunction with drawings and Examples the utility model is further specified.
Figure one is that numeral is surveyed shape instrument structural drawing.
Embodiment
Shown in figure one, this device comprises transmitting illuminant cabinet 5, by support 1 collimator objective 3 and light source 2 are installed in it, in the reception ray machine case 11 of testee 6 opposite sides, an image-forming objective lens 7 focus light hurdles 9 and area array CCD 10 are installed and constitute a complete optical measuring system by support 8.On testee 6, the light of part because testee to the blocking of light, is not blocked is by image-forming objective lens 8,9 imagings on area array CCD of focus light hurdle by the emission rayed.CCD becomes electric signal to deliver to computing machine image transitions to handle, obtain testee flat shape and size on display.
Claims (1)
1 one kinds of numerals are surveyed the shape instrument, in the transmitting illuminant cabinet of testee one side, light source is arranged, collimator objective, in the reception ray machine case of another survey of testee, image-forming objective lens is arranged, light hurdle, area array CCD, it is characterized in that in the transmitting illuminant cabinet, one light source and collimator objective being installed by support, in receiving the ray machine case, image-forming objective lens is installed by support, focus light hurdle, and area array CCD has constituted a cover optical measuring system.
