英国玛奇赛兹公司研制成功一种测量装置,它可用激光束来测量圆柱形零件的直径尺寸。该装置利用激光、录像显示器和微处理机,在10秒钟内即可测量出15种直径尺寸和同心度。该装置无可动部分,因而在工厂里有较高的可靠性,其重复精度也相当良好。此外,在测量时由于不必接触被测零件,因而不必做记号,也不必担心由测量力引起的零件变形。这种装置特别适合用于校准器测量杆直径等方面的测量。 British Macchiatz company successfully developed a measuring device, which can be used to measure the diameter of cylindrical parts cylindrical diameter. With laser, video monitor and microprocessor, the device measures 15 diameter sizes and concentricities in less than 10 seconds. The unit has no moving parts and therefore has high reliability in the factory and its repeatability is quite good. In addition, the measurement does not have to touch the measured parts, so do not have to mark, do not have to worry about the deformation caused by the measurement of force components. This device is particularly suitable for measuring calibrator rod diameter measurement.
