In some embodiments, the extending lines of the first dial indicator 41 and the extending lines of the first chute 111 and the second chute 112 respectively have included angles therebetween. According to the embodiment, the first dial indicator 41, the first positioning piece 21 and the second positioning piece 22 form a triangle (namely a three-point positioning method) when the rotary part 200 is positioned, the triangle is an extremely stable structure, the rotary part 200 can be more stable in detection by using the triangle layout, and measurement errors are reduced.
In some embodiments, the angle between the mounting surface 12 and the support surface 11 is 90 °.

The application method of the embodiment comprises the following steps:
First, the standard part is placed on the supporting surface 11, the first positioning member 21 is contacted with the outer hole of the standard part, the first positioning member 21 is positioned on the diameter extension line of the standard part, and the first positioning member 21 is locked. The measuring head of the first dial indicator 41 is abutted against the outer hole of the standard part, and is pressed by 0.5mm and locked. The second positioning member 22 is then moved to slightly move the second positioning member 22 back and forth along the second chute 112. If the position of the first positioning member 21 is not suitable, the second positioning member 22 may be adjusted, so that the value of the first dial indicator 41 is substantially unchanged when the standard part is rotated, that is, the rotation center of the standard part, and finally the second positioning member 22 is locked, and then the rotary body part 200 to be tested may be detected.
Secondly, the rotary part 200 to be measured is placed at the center position, the outer hole of the rotary part 200 to be measured is abutted with the first locating piece 21, the second locating piece 22 and the first dial indicator 41, and then the inner hole of the rotary part 200 to be measured is abutted with the second dial indicator 42, and the rotary part 200 to be measured can be rotated by 360 degrees, so that the inner hole or the outer hole diameter of any angle of the rotary part 200 to be measured can be read out from the first dial indicator 41 or the second dial indicator 42 very conveniently and rapidly.
Then, the roundness calculation method is to accommodate the actual contour of the same cross section and the radius difference according to the definition specified by the form and position tolerance, that is, the maximum value and the minimum value of the numerical value of the first dial indicator 41 are obtained by rotating the rotary part 200 to be measured, and the two values are subtracted by 2. The roundness of the inner hole is obtained by a second dial indicator 42.
Then, concentricity refers to the degree that the actual circle center of two concentric circles is overlapped to reach the theoretical overlapping degree. The calculation mode is that the eccentric amount of two circles is multiplied by 2. In the measurement, if the outer circle is used as a measurement reference, the second dial indicator 42 is used to measure the inner circle, and after one rotation, the reading (maximum numerical difference) of the second dial indicator 42 is the concentricity (error numerical value).
To verify the repeatability and reproducibility of the measuring process of the detecting device, we randomly extracted four races, and measured five times of concentricity by each repetition of the detecting device to obtain the following measured data:
| Sequence number | A | B | C | D |
| 1 | 0.0105 | 0.0167 | 0.0194 | 0.0215 |
| 2 | 0.0114 | 0.0153 | 0.0203 | 0.022 |
| 3 | 0.0103 | 0.0161 | 0.0201 | 0.0212 |
| 4 | 0.0103 | 0.0162 | 0.0193 | 0.0214 |
| 5 | 0.0101 | 0.0151 | 0.0209 | 0.0212 |
| Mean value of | 0.01052 | 0.01588 | 0.02 | 0.02146 |
| Extremely poor | 0.0013 | 0.0016 | 0.0016 | 0.0008 |
Since the human factor has no influence on the measurement result, we consider the reproducibility AV to be 0.
Calculating repeatability: ev=5.15 δc (δc is the standard deviation due to repeated measurements during measurement);
Delta c＝R/D2 (where R is the very poor mean, D 2 table look-up can be obtained as 2.37);
the mean value of the very poor was calculated to be 0.0013;
i.e. ev=5.15δc=5.15× (0.0013/2.37) =0.0029;
According to the following:
P/T=9.60% or less than 10% was obtained, indicating that the detection device was acceptable.
The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model.
