[0011] Further, the actual measured offset value, the opening value and the standard range value are compared to determine whether they meet the standard, including:

[0012] If H 垂直 If the actual measured value minus the first standard range value is negative, it indicates that the to-be-measured shaft section flange 3 is low, and the to-be-measured shaft section flange 3 needs to be raised, and the raising value is H 垂直 The deviation value of the actual measured value minus the first standard range value; otherwise, the to-be-measured shaft section flange 3 needs to be lowered.

[0013] The same method is used for comparison, H 水平 If the actual measured value minus the second standard range value is negative, it indicates that the to-be-measured shaft section flange 3 is offset to the right, and needs to be adjusted to the left.

[0014] Wherein, H 垂直 The actual measured value is the offset value actually measured in the vertical direction, and H 水平 The actual measured value is the offset value actually measured in the horizontal direction.

[0015] Further, the actual measured offset value of the inclination angle and the standard range value are compared to determine whether they meet the standard, including:

[0016] If the actual measured value minus the third standard range value is positive, it indicates that the to-be-measured shaft section flange 3 is offset upward, and needs to be lowered; otherwise, it needs to be raised.

[0017] Wherein, the actual measured value A is the actual measured offset value of the inclination angle.

[0018] Further, a standard parameter interface for user input of standard range values is preset for input of standard range values.

[0019] When the first temperature and the second temperature are determined, the allowed range of the flange outer circle offset in the vertical direction and the horizontal direction is determined, and when the actual measured temperature is between the first temperature and the second temperature, the linear interpolation method is used to calculate the allowed range of the flange outer circle offset in the vertical direction and the horizontal direction when the actual measured temperature is determined.
