Description
Technical field: [0001] The invention relates to a measuring device for calibrating the display value error of a measuring rod with an internal thread micrometer and an external thread micrometer used in the machining industry for detecting the pitch diameter of a thread. Background technique: [0002] At present, when verifying the indication error of the internal thread micrometer and the indication error of the external thread micrometer calibration rod, the method adopted is: on a vertical optical meter or a vertical length measuring instrument, use three-needle and four-equal gauge blocks with the aid of Groove gauges are verified by comparison. There are certain limitations in the current verification method. The length of the external thread micrometer calibration rod is only within the measurement range of the vertical optical meter or vertical length measuring instrument (the measuring range of the vertical optical meter or vertical length measuring instrument is 10...
