Problems solved by technology

At present, most of the horizontal axis fine-tuning adopts two methods. One is to use the detachable worm gear fine-tuning mechanism. This mechanism has the disadvantages of complex structure, many parts, high precision requirements for the worm gear, high cost, and low fine-tuning accuracy. ; The second method is to use two tops to support the four-way on both sides. This method requires two people to cooperate front and back, and there must be a support plane on which the top can be placed. When the height of the horizontal axis is high or there is no support plane, this method The use of this method is limited. Therefore, it is imperative to develop a telescope with a simple structure, high fine-tuning accuracy, and easy disassembly, and a fine-tuning mechanism for theodolite horizontal axis detection and calibration.

Abstract

The invention discloses a fine-tuning device for detecting and tuning the horizontal axis of a telescope and a theodolite which relates to a fine-tuning device for a detecting instrument. The fine-tuning device comprises a full-circle slide unit, a fine-tuning screw, a fine-tuning sliding block, a fine-tuning base, an ejector pin, a spring and a spring sleeve. The full-circle slide unit is fixed to a cross of the telescope or the theodolite; the fine-tuning sliding block is fixed on the full-circle slide unit; the fine-tuning screw penetrates through a top plate of the fine-tuning base and supporting the fine-tuning sliding block; the spring sleeve is arranged on a lower plate of the fine-tuning base; the ejector pin is arranged inside the spring sleeve; the lower end of the ejector pin penetrates through the upper end of the spring sleeve and is connected with the spring inside the spring sleeve while the upper end of the ejector pin props up the fine-tuning sliding block; and the fine-tuning base is fixed on a column of the telescope or the theodolite. The fine-tuning device has simple structure, convenient operation, low cost, high fine-tuning precision, convenient disassembly and wide application.

Description

technical field [0001] The invention relates to a fine-tuning mechanism of a detection instrument, in particular to a fine-tuning mechanism for detecting and calibrating the horizontal axis of a telescope and a theodolite. Background technique [0002] The telescope and theodolite are composed of two mechanical axes, the azimuth axis and the horizontal axis, and an optical axis. The three axes should be vertical in theory, but due to processing and assembly errors, the three axes are not vertical, and the horizontal axis and the azimuth axis are not perpendicular. The degree error is the tilt error of the horizontal axis, and the perpendicularity error between the optical axis and the horizontal axis is called the collimation error of the boresight axis. After the telescope and theodolite are assembled, these two errors need to be inspected and corrected to meet the technical specification requirements. During the detection process, it is necessary to align the visual axis ...
