JJF1001-1998 General measurement terms and definitions JJF1059-1999 Measurement Uncertainty Evaluation and Representation JJF1094-2002 Technical Specifications for Measuring Instrument Characteristics GB/T 9058-2004 odd ditch micrometer When using this procedure, care should be taken to use the current valid version of the above cited documents.3 OverviewThe odd-numbered ditch micrometer is a length measuring instrument using a spiral vice principle and a V-shaped anvil, and its outline drawing and The differential structure is shown in Figure 1. It is mainly used to measure the production of odd bisectors and teeth (such as taps, reapers, etc.). Measuring tool for diameter size. The odd-numbered ditch micrometer is divided into three types. three ditch micrometers, five ditch micrometers, and seven ditch micrometers. Three groove micrometer V-shaped surface The angle α is 60°, and the measurement range is (1~15)mm, (5~20)mm, (20~35)mm, (35~50)mm, (50~65)mm, (65~80)mm six kinds; the five-channel micrometer V-shaped surface angle α is 108°, the measurement range is (5~25)mm, (25~45)mm, (45~65)mm, (65~85)mm four; seven groove micrometer V shape The angle α of the surface is 128°34'17′′, and the measurement range is (5~25)mm, (25~45)mm, (45~65)mm. (65~85) mm four.4 Metrological performance requirements4.1 Force measurement The odd-numbered micrometer measuring force should be in the range of (5~10)N. 4.2 scribe line width and width difference The width of the longitudinal line on the fixed sleeve and the score line on the differential cylinder are (0.15~0.20) mm, and the difference in the width of the line is not More than 0.03mm. 4.3 The relative position of the end face of the tapered cone and the millimeter line on the fixed sleeve When the lower limit of the measurement is adjusted correctly, when the zero line of the differential cylinder is aligned with the longitudinal line of the fixed sleeve, the cone of the differential tube The end face should be tangent to the right edge of the fixed casing. If it is not tangent, the pressure line should not exceed 0.05mm, and the line should not exceed 0.1mm. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJG 182-2005_English be delivered?Answer: Upon your order, we will start to translate JJG 182-2005_English as soon as possible, and keep you informed of the progress.
