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...

The invention relates to a method for assembling and adjusting, in particular to a method for assembling and adjusting the pitch axis system of a large-scale theodolite for astronomical observation. The purpose of the present invention is to solve the technical problems that the existing installation and adjustment methods of the theodolite pitch shaft system for large-scale astronomical observation have great difficulty in installation and adjustment, and the installation and adjustment process is time-consuming and laborious, and provides a kind of installation and adjustment of the theodolite pitch shaft system for astronomical observation. method. This method strictly controls the grinding of the left column and the right column, the boring process of the left bearing mounting hole of the left bearing seat and the right bearing mounting hole of the right bearing seat during the assembly and adjustment process. The connection between the right shaft system component and the optical system structural components is cleverly ensured by the hinge pin method to ensure the connection requirements of the axial dimension chain, which greatly improves the adjustment accuracy of the pitch shaft system, and omits the left shaft system component and the right shaft system. The adjustment process of component coaxiality error greatly reduces the difficulty of installation and adjustment, shortens the installation and adjustment cycle, and saves the installation and adjustment cost.
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...
