Specifically, as shown in fig. 4, 5 and 6, the gauge of the present invention includes a dial gauge assembly and a reference correction block 1, the dial gauge assembly is mounted on a main body bracket 2, a measurement platform 3 is formed on the upper portion of the main body bracket 2, the dial gauge assembly includes a dial gauge 4 and a measuring pin 5, the reference correction block 1 has a measurement bottom surface 11 and a measurement contact surface 12, the measurement bottom surface 11 of the reference correction block 1 is supported on the measurement platform 3 when the gauge is in use, the top end of the measuring pin 5 is in contact with the measurement contact surface 12 of the reference correction block 1, the vertical distance between the measurement bottom surface 11 and the measurement contact surface 12 is an installation reference height H, and the installation reference height H is 14.9 ± 0.05mm in this embodiment.
Specifically, in this embodiment, the reference correcting block 1 has a detection reference groove 13, the detection reference groove 13 is formed by opening the bottom of the reference correcting block 1, and the depth of the detection reference groove 13 is the installation reference height H. In practical implementation, the structure of the reference calibration block is not limited to that disclosed in this embodiment, and any structure design may be used as long as the installation reference height can be verified, that is, the reference calibration block 1 is provided with the measurement bottom surface 11 and the measurement contact surface 12 having the functions of the present application, which is the protection scope of the present invention.
When the checking fixture is used, the bottom surface 7 of the ABS electromagnetic valve iron core component to be detected is supported on the measuring platform 3, and the sealing surface 6 of the ABS electromagnetic valve iron core component to be detected is in pressing contact with the top end of the measuring pin 5.
