Abstract

The invention discloses a space two-sphere center distance measuring instrument and a measuring method thereof. The measuring instrument comprises a fixed measuring rod module, a high precision one-dimensional displacement table module, a connecting block module, a variable measuring rod module, and a variable measuring rod probe module. The measuring instrument can measure the distance between the two standard sphere centers by geometric operation. The measurement process of the space sphere measuring instrument is more simple and convenient, the measurement cost is saved to a great extent and the good measurement precision for the relative position of various spheres in a wide range is guaranteed.

Description

technical field [0001] The invention relates to the technical field of length verification, in particular to an instrument for measuring the distance between two sphere centers in space and a measuring method thereof. Background technique [0002] For the three-dimensional space standard court, the volume of the space standard court is relatively large and heavy. In order to measure the spatial distance between any two centers of the spheres, a Laser Tracker (laser tracker) or a Laser Tracer multi-station method is usually used for measurement. However, the price of instruments such as Laser Tracker or Laser Tracer is quite expensive, usually more than 1 million RMB. Moreover, ordinary ranging tools such as screw micrometers cannot detect the spatial distance between any two centers of spheres. Therefore, it is urgent to find a high-precision and low-cost method that can measure the distance between two sphere centers in space. Contents of the invention [0003] The obj...
