Embodiment Construction

[0014] Below in conjunction with embodiment the method of the present invention is described in further detail.

[0015] A kind of theodolite turntable is leveled according to the method of the present invention, with the inclinometer with two orthogonal test axes as the test tool, press figure 1 As shown, the inclinometer 1 is set at the center of the turntable surface 2 to be leveled, so that the two orthogonal test axes of the inclinometer are parallel to the turntable surface, and the leveling is carried out according to the following steps:

[0016] a. Let one test axis of the inclinometer be the X axis, and the other test axis be the Y axis, and record the inclinometer at the initial position I (such as figure 2 Shown in position I) the inclination angle value of the output of the two test shafts is θ X1 , θ Y1 ;

[0017] b. Then turn the inclinometer 180° together with the turntable to position II, and record the position of the inclinometer at this position II (suc...

Abstract

The invention relates to a rapid and accurate leveling method for a turntable, i.e. a rapid leveling method for a turntable, utilizing an inclinometer with two orthogonal testing axis as the testing tool, placing the inclinometer at the center of the table facet of the turntable to be leveled, enabling two orthogonal testing axis of the inclinometer to be parallel to the table facet of the turntable, firstly, measuring the inclination angle value ThetaX1 and ThetaY1 outputted by two testing axis when the inclinometer is at the initial position I, then rotating the inclinometer along with the turntable 180 degrees to the position II and measuring the inclination angle value ThetaX2 and ThetaY2 outputted by two testing axis when the inclinometer is at the position II; respectively calculating the average value of the inclination angle of the two axis of the inclinometer at the position I and the position II by the following equation: ThetaX equals to sum of ThetaX2and ThetaX1 and divided by two, ThetaY equals to sum of ThetaY2 and ThetaY1 and divided by two; adjusting a leveling mechanism under the base of the turntable to enable the inclination angle value ThetaX and ThetaY outputted by two testing axles of the inclinometer to simultaneously meet that ThetaX equals to ThetaX and ThetaY equals to ThetaY, then the turntable is in the horizontal status. The rapid and accurate leveling method for the turntable has the advantages of high leveling accuracy, rapid leveling speed and being adaptable for the severe environment change.

Description

technical field [0001] The invention relates to a method for quickly and accurately leveling a turntable. Background technique [0002] Leveling is a prerequisite for the normal operation of many equipment, especially for some high-precision equipment, the leveling accuracy directly affects the performance and overall accuracy of the equipment. [0003] At present, the leveling methods mainly include water bubble leveling and electronic level leveling. The leveling accuracy of water bubbles is low (the resolution of high-precision water bubbles is generally 20″), and the installation process is complicated. After the calibration is completed, the adjustment accuracy can reach within 10″. When it is large, the water bubble cannot guarantee the leveling accuracy requirement at all. The electronic level is a high-precision angle measuring device (the resolution is generally 2″, and the high precision can reach 0.2″). However, due to its complex structure, large volume, and la...
