[0042] In the embodiment, the limiting mechanism is arranged on the base 1, comprising first limiting rods 3, second limiting rods 4 and third limiting rods 5 evenly distributed along the outer frame of the base combination;

[0043] Further, the limiting rods form a limiting frame, which is adapted to the outer contour of the base combination, used for limiting the position of the base combination during installation, ensuring its stability and accuracy during detection.

[0044] In the embodiment, the pressing mechanism is arranged above the mounting mechanism 2, used for applying a certain downward pressure to the base combination, to ensure that it does not move during detection.

[0054] Then, the first limiting rod 3, the second limiting rod 4 and the third limiting rod 5 in the limiting mechanism are used to limit the base assembly to ensure the accuracy of the installation position.

[0055] Next, the operator covers the calibration block 11 above the displacement sensor 9 for calibration, and removes the calibration block 11 after the calibration is completed.

[0056] Then, the pressing cylinder 6 drives the pressing rod 7 and the pressing head 8 to apply a pressing force to the base assembly, the displacement sensor 9 starts to detect the distance between the base assembly and the preset 0-degree reference point, and transmits the detection data to the displacement sensor amplifier 10 for processing and display.

[0057] The operator can judge whether the gap size of the base assembly meets the standard according to the display result.
