Embodiment Construction

[0018] Below in conjunction with embodiment the method of the present invention is described in further detail.

[0019] A kind of theodolite turntable is carried out leveling by the method of the present invention, with the inclinometer as test tool, press figure 1 As shown, set the inclinometer 1 at the center of the turntable surface 2 to be leveled, so that the test axis of the inclinometer is parallel to the turntable surface, and perform leveling according to the following steps:

[0020] a. Turn the inclinometer to the initial position I where its test axis is parallel to the line between the two height adjustment mechanisms 4 and 6 under the turntable base 3 (such as figure 2 Shown in I), record the inclination angle value of the test shaft output when the inclinometer is at the initial position I X+ ;

[0021] b. Turn the inclinometer 180° together with the turntable to position II (such as figure 2 II), record the inclination angle value of the test shaft output...

Abstract

The invention relates to a rotary table leveling method that can fast and correctly level a rotary table, taking an inclinometer as a testing tool. The inclinometer is arranged in the center of the surface of the rotary table to be leveled; the inclinometer is rotated to an initial position I that is mutually parallel to a connecting line of any two height adjusting mechanisms under the base of the rotary table, and the inclination angle of the initial position I, namely, Theta X+ and the inclination angle of a position II opposite to the initial position I, namely, Theta X- are measured; the Theta X is figured out to be equal to one second of Theta X+ added with Theta X-; the two height adjusting mechanisms are adjusted, and the inclination angle, namely, Theta X, output by a testing axle is caused to be equal to Theta X; the inclinometer is rotated by 90 degrees to a position III; by the same way, the inclination angles of the position III and a position IV are measured to be Theta Y+ and Theta Y-; Theta Y is figured out to be equal to one second of Theta Y+ added with Theta Y-; by adjusting the other height adjusting mechanism under the base of the rotary table, the inclination angle of the position IV, namely, Theta Y, output by the testing axle of the inclinometer is caused to be equal to Theta Y, thus finishing the leveling of the rotary table. The rotary table leveling method is characterized by high leveling precision and being capable of adapting to severe environment change, and overcomes defects existing in the traditional leveling method.

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...
