Embodiment Construction

[0036] The present invention will be further described below in conjunction with accompanying drawing.

[0037] The method for installing and adjusting the theodolite pitch axis system for astronomical observation provided by the invention comprises the following steps:

[0038] 1) Take the horizontal plane of the installation bearing surface between the U-shaped frame base 1 and the azimuth shaft system as the horizontal reference plane, and grind the upper surfaces of the left column 2 and the right column 3 on the grinding machine at the same time to ensure that the left column 2 and the right column 3 The same height, and the upper surfaces of the two are parallel to each other, and meet the process requirements for the degree of parallelism;

[0039] 2) if image 3 As shown, the ground left column 2 and right column 3 are symmetrically arranged on the left and right ends of the U-shaped frame base 1 to form the lower end of the U-shaped frame;

[0040] 3) if Figure 4A...

Abstract

The invention relates to an adjusting method, in particular to an adjusting method of a pitch shafting of a large theodolite for astronomical observation. The adjusting method of the pitch shafting ofthe theodolite for astronomical observation is provided for the purpose of solving the technical problems that an existing adjusting method of the pitch shafting of the large theodolite for astronomical observation is high in adjusting difficulty, and time and labor are wasted in the adjusting process. According to the method, the grinding process of a left stand column and a right stand column and the boring process of a left bearing mounting hole of a left bearing seat and a right bearing mounting hole of a right bearing seat are strictly controlled in the adjusting process, and a left shafting assembly and a right shafting assembly are connected with an optical system structural part, so that the connecting requirement on an axial dimension chain is ingeniously guaranteed in a pin-hinging mode, the adjusting precision of the pitch shafting is greatly improved, the coaxiality error adjusting process of the left shafting assembly and the right shafting assembly is omitted, the adjusting difficulty is greatly lowered, the adjusting period is shortened, and the adjusting cost is saved.

Description

technical field [0001] The invention relates to an installation and adjustment method, in particular to an installation and adjustment method for the pitch axis system of a large-scale theodolite used for astronomical observation. Background technique [0002] Theodolite is widely used in the field of precision mechanical engineering as a kind of measuring equipment. It usually consists of a pitch axis system and an azimuth axis system. The measurement accuracy of the pitch axis system is an important link that affects the measurement accuracy of theodolite. The basic structure of the theodolite is as follows: figure 1 As shown, the pitch axis system 02 is installed on the upper part of the azimuth axis system 01, including the U-shaped frame 021, the left bearing, the left axis system 022, the right bearing, the right axis system 023 and the optical system 024, and the optical system 024 includes the optical system structure 0241 And the optical components inside it; the k...
