What are the classifications of image measuring instruments?

The measured object is imaged by high-power optical microscope, and the enlarged image of the object is sent to the computer by CCD camera system, which can efficiently detect the contour, surface shape, size, angle and position of various complex workpieces, especially the microscopic inspection and quality control of precision parts. The measured data can be directly input into AUTOCaD to become a complete engineering drawing, and the drawing can generate DXF documents, and can also be input into WORD and EXCEL for statistical analysis, and a simple Xbar-S control chart can be drawn, and various parameters such as CA can be obtained. Classification: According to its projection path, it can be divided into (a) vertical projector (b) floor projector (c) horizontal projector. After the projector and light bulb are powered on, the light passes through the filter thermal lens, lens group, workbench plate, reflector, projection screen and so on. The outline or surface of the workpiece is enlarged and projected onto a translucent projection screen. It is usually necessary to adjust the focal length between the workpiece and the projection lens to make the projection screen in the clearest state to ensure the accuracy of workpiece measurement. The structure of the image measuring instrument can be different from three different measuring systems. Taking a vertical projector as an example, the magnification of its projection lens can range from 25x to 225x, and there are four commonly used types: 10x, 20x, 50x and 100x. The measuring workpiece can be illuminated by contour illumination or surface reflection. Accessories include rotating stage, indexing head (mechanical or optical), display, V-shaped block, central top frame, lenses with various magnifications (which can be replaced at will), projection screen, standard pictures, glass ruler and photographic equipment. Classification of image measuring instruments: image measuring instrument, 2D image measuring instrument, 2D image measuring instrument, automatic image measuring instrument, 2D image measuring instrument, 2.5D image measuring instrument, image mapping instrument, etc. In addition to the general classification of image measuring instruments, with the increasing demand of some industries, there are also special image measuring instruments on the market, such as axial image measuring instruments and gear image measuring instruments. Usage: This instrument is suitable for all application fields with the purpose of two-coordinate measurement, and is widely used in machinery, electronics, instruments, hardware, plastics and other industries. (Mould, screw, metal, fittings, rubber, PCB, spring, hardware, electronics, plastic) Working principle: The image measuring instrument uses its own hardware (CCD, eyepiece, objective lens data line) to transmit the collected image to the data acquisition card of the computer through the data line, and then the software image is displayed on the computer, and the operator uses the mouse to make rapid measurement on the computer. The above processes are basically completed in tens of thousands of seconds, so it can be regarded as real-time detection equipment, or in a narrow sense, it can be called dynamic measurement equipment. If the configuration meets the requirements, the device will never produce image lag. According to the size of the workpiece, the workbench can choose different strokes. The brightness of the light source is adjustable, and the most suitable brightness can be selected under various light conditions. Measurement function 1, multi-point measurement of points, lines, circles, arcs, ellipses and rectangles to improve measurement accuracy; 2. Combination measurement, center point structure, intersection point structure, line structure, circle structure and angle structure; 3. Coordinate translation and coordinate alignment to improve the measurement efficiency; 4. Macro instruction makes the batch measurement of the same workpiece more convenient and faster, and improves the measurement efficiency; 5. The measured data is directly input into AutoCAD to become a complete engineering drawing; 6. The measured data can be input into Excel or Word for statistical analysis, and a simple Xbar-S control chart can be cut out to obtain various parameters such as Ca. 7. Multi-language interface switching; 8. Record user programs, edit instructions, and teach implementation. 9. large map navigation function, knife mold three-dimensional rotating light, 3 D scanning system, fast autofocus, automatic zoom lens. 10, optional contact probe measurement, used for contact measurement of irregular products, such as ellipse, radian, flatness and other dimensions; 1 1 In addition, the image measuring instrument can also detect the roundness, straightness and radian of circular objects, and the images drawn under the imager can be directly saved as dxf files, which can be directly opened in autocad software! You can also import 3D software 13. If you add the probe to the image measuring instrument, you can directly dot it with the probe and then import it into reverse engineering software for further processing! Software can freely realize the mutual conversion between probe and image! 14. Flatness detection (the flatness of products can be detected with a laser probe, and it is recommended to use the "Qihai Optoelectronics" laser probe for flatness detection).
