Description

Adjusting method of theodolite pitching axis for astronomical observation
Technical Field
The invention relates to an assembly and adjustment method, in particular to an assembly and adjustment method of a large-scale theodolite pitching axis for astronomical observation.
Background
The theodolite is widely used in the field of precision mechanical engineering as a measuring device, and generally comprises a pitch axis system and an azimuth axis system, wherein the measurement precision of the pitch axis system is an important link influencing the measurement precision of the theodolite. The theodolite is basically structurally shown in fig. 1, a pitching axis 02 is arranged at the upper part of an azimuth axis 01 and comprises a U-shaped frame 021, a left bearing, a left axis 022, a right bearing, a right axis 023 and an optical system 024, and the optical system 024 comprises an optical system structural part 0241 and an optical element positioned in the optical system structural part 0241; the pitching shafting 02 is characterized in that a key part is a U-shaped frame 021, a left arm of the U-shaped frame 021 bears a left shafting 022 through a left bearing, a right arm of the U-shaped frame 021 bears a right shafting 023 through a right bearing, and the left shafting 022 and the right shafting 023 are respectively connected with the left side and the right side of an optical system structural part 0241.
For a small theodolite, the overall size of the U-shaped frame 021 is small, so that the theodolite can be designed to be of an integral structure. The installation and adjustment sequence of the pitching shafting 02 is generally as follows: a left shaft system 022 is installed on a left arm of a U-shaped frame 021 through a left bearing, a right shaft system 023 is installed on a right arm of the U-shaped frame 021 through a right bearing, and then an optical system 024 is connected between the left shaft system 022 and the right shaft system 023. The U-shaped frame 021 of overall structure form, easily processing, left shafting 022 and the axiality of right shafting 023 rely on the course of working mainly to guarantee. The dimension chain of the theodolite pitching axis 02 is a left axis 022, an optical system 024 and a right axis 023 which are connected in sequence, belongs to a single serial structure, and can be guaranteed by means of a machining process.
For a large theodolite, for example, astronomical observation equipment, because the size of its parts, especially a U-shaped frame, is large, if the theodolite is designed into an integral structure, it is difficult to complete the processing on one processing equipment to meet the requirements of design dimension error and behavior error (including position error and shape error), and even if there is only a local error, the accuracy of the observation result is greatly affected. Therefore, in general, the U-shaped frame of the large theodolite needs to be designed into a split structure and is formed by combining a plurality of sections. As shown in figure 2, the U-shaped frame 025 consists of a U-shaped frame base 0251, a left upright post 0252 and a right upright post 0253 which are symmetrically arranged at the left end and the right end of the U-shaped frame base 0251, a left bearing seat 0254 arranged on the left upright post 0252 and a right bearing seat 0255 arranged on the right upright post 0253. This theodolite every single move shafting 02's U type frame 025's left bearing frame 0254 passes through left bearing and left shafting 022 constitution left shafting subassembly, and right bearing frame 0255 passes through right bearing and right shafting 023 constitution right shafting subassembly, connects optical system 024 between left shafting subassembly and the right shafting subassembly, forms the axial dimensions chain.
The U-shaped frame 025 of the large theodolite adopts a split type combined structure design, which brings certain convenience to processing and manufacturing, but brings great difficulty to the adjustment of the pitching axis 02 of the theodolite. This is because the coaxiality error of its left bearing frame 0254 and right bearing frame 0255 has decisive influence to the assembly precision of pitch shafting 02, needs to guarantee through the assembly technology, and general assembly thinking is: when the coaxiality error of the left shafting assembly and the right shafting assembly is adjusted, the axial dimension chain of the left shafting assembly and the right shafting assembly is ensured to meet the requirement, namely the distance between the mounting flange of the left shafting 022 and the mounting flange of the left end of the optical system structural member 0241 and the distance between the mounting flange of the right shafting 023 and the mounting flange of the right end of the optical system structural member 0241 both meet the requirement of distance tolerance, and because the flange of the large structural member belongs to a moving part in the structural system, the dimension measurement is difficult, the measurement error is large, so the precision of the pitching shafting 02 is easily damaged and the shafting rotation is not smooth. Therefore, the whole installation and adjustment process is difficult, time-consuming and labor-consuming.
