(4) measure the accurate indicating value of this circular diameter, generally at least survey 5 times, get its mean value, this mean value is ring gauge working size measured value in that direction; Then pen is painted or the position of measured value and measurement is labeled on ring gauge end face by electric engraver;
(5) repeat step (3) and (4), measure the circular diameter in three cross sections, ring gauge upper, middle and lower respectively, and carry out taperness error evaluation, evaluation result should meet designing requirement; Otherwise, need to scrap or do over again process to above-mentioned ring gauge.
Further, the base measuring temperature of described calibration steps is 20 DEG C ± 2 DEG C, and humidity is < 85%RH.
Further, the time of described equalized temperature is ≮ 8h.
A kind of major diameter stripe shape ring gauge being exclusively used in method described above, it is characterized in that: comprise rectangular ring gauge body, described ring gauge body offers rectangle groove, the ring gauge body at the two ends of described rectangle groove is provided with step, and the end face center of the ring gauge body at the two ends of described rectangle groove is provided with slotted line.
Further, the surface roughness Ra of described rectangle groove is 0.1 μm ~ 0.4 μm.
Further, the measuring error of described ring gauge can be controlled in 0.003mm.
Through detection qualified after stripe shape ring gauge, at the scene use time should be noted: treat that ring gauge body temperature and scene temperature will keep equal, can use, otherwise can certain error be caused.
When the present invention uses, stripe shape ring gauge lies against on flat board; get dial framework and carry out his-and-hers watches, according to ring gauge slotted line that center indicates, need higher than 5mm during dial framework his-and-hers watches; get out of the way arc-shaped transitional surface bottom dial framework; bob and weave, and get center peak, clock gauge is arranged on dial framework one end and zeroing; the dial framework other end is by top fixing, and his-and-hers watches complete.Can with product actual measurement, reading numerical values, error can be controlled in 0.003mm.
Beneficial effect of the present invention is embodied in:
1, stripe shape ring gauge is easily taken care of, and stock utilization is high, the problem of good stability of the dimension;
2, easily grasp in actual in-process measurement, and accurately reflect product size really, by carrying out size comparison with CMM equipment, measured value is consistent, and error, substantially within 0.003mm, meets and measures requirement;
3, detection method of the present invention not only saves cost of manufacture but also product quality is guaranteed, and reaches technological requirement, has successfully captured a measurement difficult problem for large-diameter workpiece.
