No matter it is logical groove and still the through-hole, its effect lies in realizing the degree of freedom restraint of calibration piece in first frock seat, realizes the motion restraint of calibration piece in the appointed orientation in space to ensure that the calibration piece can accurately move to the assigned position department of the axle type part 01 that awaits measuring, get rid of because of operating personnel's error to the inspection operation introduction error of the axle type part 01 that awaits measuring.
In order to achieve better technical effects, the holes of the first positioning clamp 1 and the holes of the second positioning clamp 2 are distributed coaxially. The difference between the diameter of the hole of the first positioning card 1 and the target diameter of the shaft part 01 to be measured is the maximum processing tolerance of the shaft part 01 to be measured. For example, if the design size of the shaft part 01 to be measured isdAnda + ba, the target diameter of the shaft part 01 to be measured is d, and the diameter of the hole of the first positioning card 1 is d + a. Similarly, the difference between the diameter of the second positioning card 2 and the target diameter of the shaft part 01 to be measured is also the maximum processing tolerance of the shaft part 01 to be measured. The first positioning clamp 1 and the second positioning clamp 2 with the size characteristics can be used for judging whether the shaft diameter of the shaft part 01 to be detected is not larger than a preset value, namely d + a.
