Abstract

The invention relates to an angle measuring mechanism which comprises an angle measuring light pipe, a connecting rod set, a rotating hand wheel, an angle measuring seat, a coded disc, a bubble seat, a fine adjustment hand wheel, a release locking hand wheel, a leveling assembly and an inserting rod, the angle measuring seat is of a box body structure, a rotating shaft system is arranged in the angle measuring seat, and the rotating shaft system comprises a rotating seat, a steel ball, a steel ball space ring, a rotating shaft and a rotating seat pressing ring. The angle measuring light pipe, the connecting rod set, the rotating hand wheel, the rotating shaft and the code disc are sequentially connected, the bubble base is arranged on the upper surface of the angle measuring base, the fine adjustment hand wheel and the unlocking and locking hand wheel are installed on the side face of the angle measuring base, the leveling assembly is connected with the lower surface of the angle measuring base through screws, and the inserting rod is installed at the bottom end of the leveling assembly. The high-precision and large-stroke slewing mechanism is used for controlling the angle measuring light pipe to be optically aligned with the measured equipment, the measured equipment can measure the angle at any angle, the limitation of the fixed angle of a zenith instrument and a general goniometer is avoided, and the whole structure is lighter and easier to carry, easy to operate and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of optical detection equipment, in particular to a continuous large-scale high-precision angle measurement mechanism. Background technique [0002] The angle measuring mechanism is mainly used to realize the detection of the azimuth angle, elevation angle, vertical deviation and other performance of optical and photoelectric equipment. At present, the measurement technology of azimuth angle is relatively mature, and there is a shortage of continuous and large-scale angle detection of high and low angles. Among the commonly used goniometer mechanisms, fixed zenith instruments and general-purpose goniometers are the main ones. Multiple goniometer light pipes are installed in the vertical plane of the horizontal goniometer light pipe, and the installation of each goniometer light pipe is accurately calibrated. Position angle value, the angle that can be measured is the calibrated angle value of the installatio...
