Abstract
The present invention relates to the method quick and precisely leveled to turntable,I.e. a kind of fast leveling method for rotating platform,Be to have that there are two the inclinators of orthogonal test axis as testing tool,Inclinator is set at turntable table top center to be leveled,Two orthogonal test axis of inclinator are made to be parallel to turntable table top,First measure inclinator in initial position I two test axis output inclination angle values be θ X1,θY1; Then by inclinator with 180 ° of turntable unitary rotation to position II,In the position when II two test axis output inclination angle value be θ X2,θY2; The average value of inclination angle value of two axis of inclinator at position I and position II is calculated separately,
, so that inclinator two is tested inclination angle value θ X, the θ Y of axis output by adjusting the levelling mechanism under turret base, until meeting simultaneously
,
When, turntable is leveling state. The method of the present invention has the characteristics that leveling precision is high, leveling speed is fast, adapts to adverse circumstances variation.
Description
Technical field
The present invention relates to a kind of method of turntable being carried out leveling quick and precisely.
Background technology
Leveling is the precondition of many equipment operate as normal, and especially for some high-precision equipments, the leveling precision directly influences the performance and the overall accuracy of equipment.
At present, leveling method mainly contains bubble leveling and electrolevel leveling dual mode.Bubble leveling precision low (high precision bubble resolution is generally 20 "), and the mounting process complexity, degree of regulation can reach 10 after calibration was finished " in, but change along with conditions such as working environments, bubble deforms, and when distortion was big, bubble can't guarantee the leveling accuracy requirement at all.Electrolevel be a kind of high-precision Angle Measuring Equipment (resolution is generally 2 ", high precision can reach 0.2 "), but because its complex structure, volume are bigger, is subjected to the working environment restriction bigger simultaneously, manyly at present uses as laboratory testing equipment.Therefore, adopt new method, develop a kind of simply, reliably, the level device that can adapt to rugged surroundings has important value.
Leveling turntable has important use as leveling mode a kind of, for example transit, seek and need that turntable is carried out accurate leveling before the equipment works such as northern instrument and could guarantee measuring accuracy.Traditional leveling turntable mode is at the edge of turntable quadrature two accurate adjustment par bubbles to be installed, and by observing bubble, regulates levelling gear.This method is had relatively high expectations to the bubble installation accuracy, the installation process complexity, and bubble is yielding, is unfavorable for long-term use.
Summary of the invention
The objective of the invention is to propose a kind of fast leveling method for rotating platform, to overcome the present shortcoming that the classic method of leveling turntable is existed.
Fast leveling method for rotating platform of the present invention, be to test the inclinator of axle as testing tool to have two quadratures, be about to inclinator and be arranged at the turntable table top center for the treatment of leveling, make two quadrature test axles of inclinator be parallel to the turntable table top, carry out leveling according to the following steps:
A. a test axle of establishing in the inclinator is X-axis, and another test axle is a Y-axis, and the angle of inclination value of the two test axle outputs of record inclinator when this initial position I is θ
X1, θ
Y1
B. then with inclinator with 180 ° of turntable unitary rotation to position II, the angles of inclination value of the two test axle outputs of record inclinator when the II of this position is θ
X2, θ
Y2
C. calculate the mean value of the angle of inclination value under inclinator X-axis, Y-axis position I and the position II respectively, that is:
And write down this mean value
D. by adjusting the levelling gear under the turret base and reading in the angle of inclination value θ that II angle of declination instrument two test axles in this position are exported in real time
X, θ
Y, satisfy θ until simultaneously
X=step c record
θ
Y=step c record
The time, turntable is the leveling state.
The inventive method have leveling precision height, leveling speed fast, can adapt to the characteristics that rugged surroundings change, overcome the shortcoming that existing traditional leveling method exists.

Embodiment
Below in conjunction with embodiment the inventive method is further elaborated.
A kind of transit turntable is carried out leveling by the inventive method, test the inclinator of axle as testing tool to have two quadratures, by shown in Figure 1, inclinator 1 is arranged at turntable table top 2 centers for the treatment of leveling, make two quadrature test axles of inclinator be parallel to the turntable table top, carry out leveling according to the following steps:
A. a test axle of establishing in the inclinator is X-axis, and another test axle is a Y-axis, and the angle of inclination value of the two test axle outputs of record inclinator when this initial position I (shown in the I of Fig. 2 position) is θ
X1, θ

B. then with inclinator with 180 ° of turntable unitary rotation to position II, the angles of inclination value of the two test axle outputs of record inclinator when this position II (shown in the II of Fig. 2 position) is θ
X2, θ
Y2
C. calculate the mean value of the angle of inclination value under inclinator X-axis, Y-axis position I and the position II respectively, that is:
And write down this mean value
D. by adjusting the levelling gear 4 under the turret base 3 and reading in the angle of inclination value θ that II angle of declination instrument two test axles in this position are exported in real time
X, θ
Y, satisfy θ until simultaneously
X=step c record
θ
Y=step c record
The time, turntable is the leveling state.
