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
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 method for leveling turntable, to overcome the present shortcoming that the classic method of leveling turntable is existed.
Method for leveling turntable of the present invention, be with inclinator as testing tool, be about to inclinator and be arranged at the turntable table top center for the treatment of leveling, make the test axle of inclinator be parallel to the turntable table top, carry out leveling according to the following steps:
A. inclinator is turned to the initial position I that the inter-agency line of its test axle and any two height control under the turret base parallels, the angle of inclination value of the test axle output of record inclinator when this initial position I is θ
