Description

Image measurer

Technical field

The utility model relates to a kind of image measurer, but measurement mechanical, electronics, Aero-Space, mould, spring, gear, connection terminal, circuit board contact, five metals plastic cement, magnetic material, electronic component, wrist-watch element, hardware stamping parts, ore, and other accurate hardware belong to the measuring instrument technical field.

Background technology

Image measurer adopted the principle of optics chi location in the past, the light source halogen light source, mainly form by CCD, eyepiece, object lens, continuous zoom camera lens, X, Y, Z axis rail, cross mobile platform, X, Y, three rotary spanners of Z, X, Y, three optics chis of Z, control enclosure (control card) and video card, on board top, mainly connect eyepiece by CCD, be connected to object lens then, object lens are by the affixed continuous zoom camera lens of web member, and these four parts are mainly fixed by dull and stereotyped by the Z axis rail.And additional grating chi and rotary spanner on the guide rail.The latter half mainly drives X, Y-axis guide rail and optics chi by the cross platform, and affixed together rotary spanner, control enclosure (control card) end connects three optics chis, an other end connects the computer serial ports, guarantee the input and output of data, video line on the CCD connects the video card on the computer, guarantees that image successfully is input in the software.

With respect to ancient projector, it has feature easily and efficiently, yet because existing product drives the influence that factor and board heaviness etc. are distinguished in the trueness error, the requirement to environment light source, optics chi precision, the manual operation that bring based on image quality, worktable, cause existing product on measuring accuracy and speed, to be subjected to severely restricts, make that the general low precision of product, speed are slow, inconvenient operation, the scope of application is narrow and small and can not be used for batch detection.

Summary of the invention

The purpose of this utility model provides a kind of radiographic measurement precision height, speed is fast, easy to operate, the scope of application is wide and the image measurer of energy batch detection.

For realizing above purpose, the technical solution of the utility model provides a kind of image measurer, comprise video line, video interface, the CCD camera, link, gland, the camera lens folder, through hole, zoom lens, the glass platform, supporting base, small handwheel, Y direction grating chi, supporting seat, column, bolt, Z axle axle sleeve, screw mandrel, handwheel, base, under casing, gearing, web joint, connect cover plate, Z direction grating chi, XY worktable, directions X grating chi and Y direction transmission shaft, it is characterized in that led light source is reaching on the base under the zoom lens by bracing or strutting arrangement and screw retention; The anodontia screw rod of directions X is fixed on the base by two bearing seats, and the fast moving device is located on the anodontia screw rod; The oblique fire light source by supporting seat and screw retention on column.

The utility model has been abandoned the principle that adopts optics chi location in traditional image measurer, the structure and the structure of machine have been simplified widely, the error that the optics chi brings is removed up hill and dale, and eliminated the hardware error of machine itself, measurement on the computer is transferred in the dimensional measurement of whole work-piece, when object is amplified to certain multiple by fixing enlargement factor, the virtual image after obtaining amplifying by the image image acquistion system, the utility model are dwindled certain multiple by the fixing amplification multiple virtual image and are obtained " original virtual reality " image in computer.Thereby can access an out and out actual size figure, and needn't go to pass judgment on this product size, thoroughly remedy because the error problem that machine-building brings according to the precision of optics chi.Also can realize gathering apace image and surveying work for the finding product.Make people and machine, machine and workpiece are realized aspectant dialogue fully, replace original halogen light source with the LED cold light source, also can record higher precision for the workpiece of easy thermal deformation.Increased the oblique fire lamp source in addition, made the angle of measurement more extensive.

The utility model has the advantages that radiographic measurement precision height, speed is fast, easy to operate, the scope of application is wide and can batch detection.
