Example Embodiment

[0011] As shown in Figure 1 and figure 2 As shown, the spherical measuring prism of the present invention includes a sphere 1, a through hole 2 passing through the sphere 1 is opened on the sphere 1, the center of the sphere 1 is on the central axis of the through hole 2, and the through hole 2 is installed The back cover 5, the positioning angle couple 3, the glass pyramid 4 and the front cover 6, the rear cover 5 is installed in the through hole 2 of the sphere 1 by threads, the positioning angle couple 3 is slidingly fitted in the through hole 2, and the glass pyramid 4 is installed on the positioning angle couple 3 and forms a sliding fit with the through hole 2, and the front cover 6 is installed in the through hole 2 of the ball 1 through threads.

[0012] The key point of the present invention is that the positioning angle pair 3 matched with the glass pyramid 4 is provided, and a pyramid is cut out in the middle of the positioning angle pair 3 to make the three mutually pe...

Abstract

The invention provides a spherical measuring prism with convenient adjustment and difficult-changed position of a glass pyramid. The spherical measuring prism comprises a sphere. A through hole penetrating through the sphere is opened on the sphere and the ball center of the sphere is on the axle wire of the through hole. The through hole is internally provided with a rear cover, a positioning corner, the glass pyramid and a front cover. The rear cover is installed in the through hole of the sphere and the glass pyramid is installed on the positioning corner while the front cover is installed in the through hole. The spherical measuring prism of the invention can drive the glass pyramid to move backwards by installing the front cover so as to ensure that three mutually vertical surfaces on the glass pyramid are closely contacted with the positioning corner, and accurately cause the superposition of the reflection center of the glass pyramid and the ball center of the sphere by controlling the working accuracy of components and back and forth adjustment when in installation, therefore, the position of the glass pyramid after installation is not easy to change.

Description

technical field [0001] The invention relates to a measuring prism, in particular to a spherical measuring prism. Background technique [0002] In the field of surveying and mapping, the three-dimensional coordinates of the measuring prism can be obtained through the measurement of the measuring prism by the total station, so that the spatial position of the measured object can be indirectly reflected according to the fixed relationship between the placement position of the measuring prism and the measured object. Therefore, the accuracy of the measuring prism directly affects the final measurement accuracy. [0003] The measuring prism is a glass pyramid with 3 mutually perpendicular faces and 1 cutting face, and the 3 mutually perpendicular faces intersect to form a pyramid. The three mutually perpendicular surfaces are surface-treated with a mirror-making process, so that the interior becomes a reflective mirror surface, so that no matter what angle the incident light ent...
