Generally, for a revolving body shaft/aperture measuring device, when the direction of a laser range finder needs to be accurately adjusted, a direction fine adjustment mechanism is arranged, wherein the direction fine adjustment mechanism comprises a left fine adjustment mechanism, a right fine adjustment mechanism, an up and down fine adjustment mechanism and a vertical fine adjustment mechanism of the laser range finder in the longitudinal direction (laser emission direction), and the specific structure comprises thread fine adjustment (shown in fig. 5) or ultra-thin gasket fine adjustment; the position of the ranging starting point (sometimes also called as the ranging origin) generally does not need to be finely adjusted, the later calibration is needed, if the adjustment is needed, the adjustment of the front and rear positions of the laser range finder can be carried out through the comparison of the ranging values, and of course, the measuring device needs to be provided with a fine adjustment structure of the mounting position of the laser range finder, such as a front and rear translation fine adjustment structure, a left and right translation fine adjustment structure and the like; the specific position method is that when the inner diameter measuring device is adjusted, the measuring device is arranged at the center of the standard double-ring type calibration piece, the direction is adjusted to be in place, then whether the ranging value of each laser range finder meets the design index is compared, and the adjusting method of the outer diameter measuring device is similar.

Because two adjustment designs of the reticle and the beam through hole are adopted at the same time, the purpose of separating the horizontal adjustment and the vertical adjustment of the light emitted by the laser range finder is achieved, and the independent adjustment can be realized without mutual influence; although in principle, the adjustment target can be realized by firstly adjusting the light horizontally, then vertically, firstly adjusting the light vertically, secondly adjusting the light horizontally, and then directly aiming at the final target level and the vertical synchronization or cross adjustment of the light passing through the center of the through hole of the light beam, from the convenience angle of practical engineering implementation, the measuring device and the auxiliary adjusting device are relatively put in place, and then the vertical direction of the light is firstly adjusted according to the scribing line, and then the horizontal direction of the light is adjusted according to the through hole of the light beam, so that the adjustment is simpler and smoother, and the adjustment can be realized in place by generally adjusting the light beam twice, thereby further improving the installation adjustment efficiency of the measuring device for the shaft hole diameter of the revolving body. This is also a second prominent advantage of the method of the invention.
