[0017] Ten hexagon socket screws 8 are provided on the lower side of the gauge base plate 4. All the hexagon socket screws 8 pass through the screw holes provided on the lower side of the gauge base plate 4 and are respectively connected to the gauge fixing seat 1, the gauge body 6 and the two gauge limit blocks 9. The gauge fixing seat 1, the gauge body 6 and the two gauge limit blocks 9 are fixed by providing the hexagon socket screws 8.

[0020] The working principle of this utility model is as follows:

[0021] 3, and then the hexagon socket screw 8 is used to lock the gauge fixing seat 1 and the gauge cylinder 6 to the gauge base 4. The installation position is determined by the first positioning pin 2 and the second positioning pin 3. The installed component is locked by the hexagon socket screw 8. Then the part to be measured 5 is placed inside the gauge fixing seat 1 through the gauge cylinder 6 to complete the radial positioning of the part. This part also detects whether the flat position size of the part meets the design requirements. The left end faces of the gauge fixing seat 1 and the sliding measuring block 7 are respectively provided with avoidance holes to avoid the raised parts on the parts.

If it cannot pass smoothly, the concentricity of the part 5 to be measured is out of tolerance and does not meet the design requirements. The hexagon socket screw 8 uses an M6*30 hexagon socket screw.
