Measuring base for mounting a spherical prism and point measuring assembly with it

Abstract

The invention discloses a measurement base for installing a sphere prism and a point location measuring assembly comprising the same. The measurement base comprises a measurement seat and a point aligning pin. A point aligning hole is formed in the measurement seat. The central line of the point aligning hole is oriented along the vertical direction. At least part of inner surface of the upper part of the point aligning hole forms a placing surface, the placing surface cooperates with the external surface of a sphere prism, and the central line of the point aligning hole goes through the center of the sphere prism; the point aligning pin is cooperatively installed in the point aligning hole; and the lower end of the point aligning pin form a point fixing part, which can moving up and down along the linear line where the central line of the point aligning hole stays relative to the measuring seat. The provided measurement base is used for installing a sphere prism, can transmit the coordinates of a point location so as to determine the point location, and has the advantages of simple and compact structure, portability, user-friendliness, high precision, and high efficiency.

Description

technical field [0001] The invention relates to the technical field of engineering measuring equipment, and more particularly, to a measuring base for installing a ball prism and a point measuring assembly having the same. Background technique [0002] At present, when performing survey work, it is usually necessary to place a prism on the control point. In the engineering survey process, the combination of a tripod, a base and a prism or a combination of a center rod and a prism is generally used for point measurement. In industrial surveys, it is usually used The measuring rod and the base cooperate with the ball prism for point measurement. [0003] In the industrial measuring device in the related art, during the measurement process, when the measuring rod and the base cooperate with the spherical prism to measure, it is often necessary to shake the measuring rod to measure five coordinates, and then fit a value based on the measured five coordinate values. For a sphere...

[0003] In the industrial measuring device in the related art, during the measurement process, when the measuring rod and the base cooperate with the spherical prism to measure, it is often necessary to shake the measuring rod to measure five coordinates, and then fit a value based on the measured five coordinate values. For a sphere, the center of the fitted sphere can be used as the center of the corresponding spatial position of the control point on the target ball seat, which is inconvenient to operate and affects the measurement efficiency, and the determined point has a large error and low accuracy
