Overview With the development of domestic industrial technology, more and more industries have begun to implement "metal Charpy impact test method" The standard sample very strict requirements, so the entire testing process processed sample is qualified will directly affect the final test results. If the sample processing quality standard, then the test results are not credible, especially notch small changes can cause huge steep jump test results, especially in the critical value of the test will cause qualifying products or scrapped two diametrically opposed different outcome. To ensure qualified notch, the quality inspection is an important means of control, at present, with an optical projection magnification inspection is the only practical way. XT-50 type impact specimens projector is my company based on the actual needs of customers and GB / T299-1994 "metal Charpy impact test methods" requirements impact notch and the development of a dedicated test Charpy V-shaped and U-notch processing quality of the optical instrument, which is measured by an optical projection of the impact of the sample V-shaped and U-notch contour 50X projected onto the rear projection screen and the projector screen impact Sample V-and U-notch standard model figure compares to determine whether the detected notch is qualified. The advantage is simple, intuitive comparison. Second, the principle: the light of the projector light emitted by the condenser illumination to the object, and then zoom lens will be illuminated object contours projected onto the projection screen. If necessary, the instrument is single track lighting, light is projected through a series of optical elements in the table, and then through a series of optical elements to be tested like a clear-cut gap onto the projector. Objects and secondary reflection by the second amplifying positive image, graphics and actual samples on the projection screen seen consistent placement orientation. Third, the main parameters: projection screen diameter: 180mm Table Size: Square Table size: 110 × 125mm round table diameter: 90mm diameter glass table: 70mm table travel: longitudinal: ± 10mm transverse: ± 10mm lift: ± 12mm (no scale) Table rotation range: 0-360 ° (no scale) Magnification: Instrument Magnification: 50X objective magnification: 2.5X magnification projection lens: 20X light source (tungsten halogen lamps): 12V 100W Dimensions: 515 × 224 × 603mm (L × W × H) Weight: about 18Kg
