Magnetic measurement reflection sphere with large spherical surface

Abstract

The invention discloses a magnetic measurement reflection sphere with a large spherical surface, which is convenient in installation and adjustment and has magnetism, is used for practical measurement and particularly used for the precise measurement work such as engineering measurement and commercial measurement. The magnetic measurement reflection sphere comprises a magnetic sphere body (1), wherein a blind hole (2) is arranged in the magnetic sphere body (1), the center of sphere of the magnetic sphere body (1) is positioned on an axis of the blind hole (2), a glass reflection body (3) and a mounting frame (4) are tightly combined by controlling the process precision, then a reflection center of the glass reflection body (3) is positioned on the cylindrical axis of the mounting frame (4), the diameter of the cutting surface of the glass reflection body (3), the external diameter of the mounting frame (4) and the diameter of the blind hole (2) are consistent, the glass reflection body (3) and the mounting frame (4) are installed in the blind hole (2) and can slide in the blind hole (2) forward and backward, an adjusting ring (5) is installed at the front end of the blind hole (2) and used for fixing and adjusting the glass reflection body (3) and the mounting frame (4), an adjusting screw rod (7) is installed on the magnetic sphere body (1), and the adjusting ring (5) and the adjusting screw rod (7) are rotated to push the glass reflection body (3) and the mounting frame (4) to slide in the blind hole (2) forward and backward, so that the reflection center of the glass reflection body (3) is coincident to the center of sphere of the sphere body (1). According to the magnetic measurement reflection sphere with the large spherical surface, the sphere body has magnetism, the installation and the adjustment are convenient, the spatial position of the reflection center can not be changed no matter how the sphere body is rotated as the reflection center of the glass reflection body is coincident to the center of sphere of the sphere body, and the requirements for measuring high elevation angle and large depression angle are met due to the large spherical surface.

Description

technical field [0001] The invention relates to a measuring reflective prism, in particular to a large magnetic spherical measuring reflective prism. Background technique [0002] In the field of surveying and mapping, the total station is a very important device for obtaining spatial data. Total station, that is, total station electronic speed measuring instrument (Electronic Total Station). It is a high-tech measuring instrument integrating light, mechanics and electricity, and a surveying and mapping instrument system integrating horizontal angle, vertical angle, distance (slope distance, horizontal distance) and height difference measurement functions. Because it can complete all the survey work on the station once the instrument is placed, it is called a total station. The distance measurement principle of the total station is that the total station emits light waves, the light waves encounter the measurement object, and the light waves are reflected back, and the dis...
