Abstract

The invention discloses a device for measuring changes of six degrees of freedom of a platform space. The measuring device mainly comprises an intersection angle measurement assembly, a transverse displacement measurement assembly, a longitudinal displacement measurement triangle frame assembly and a vertical displacement measuring column assembly. By the arrangement, the problems that a conventional measuring device for the six degrees of freedom is complicated in structure and measurement process, motion precision is poor, manufacturing costs are high, and is not applicable to mass popularization are solved. The measuring method has the advantages of easiness in measuring method, simplicity in installation, wide application, and measuring results can be read directly and the like.

Description

technical field [0001] The present invention relates to a device for measuring the six-degree-of-freedom change of the platform space, in particular to a device that can measure and read the six-degree-of-freedom change of the measured platform in real time. Compared with the structure of the previous six-degree-of-freedom measuring device , has the characteristics of simple measurement method, direct reading of measurement results, easy installation and wide applicability. Background technique [0002] The six-degree-of-freedom coordinate connecting plate is usually composed of upper and lower platforms with six universal hinge points and six hydraulic cylinders. The lower platform is usually fixed. As a static platform, the upper platform is The six-degree-of-freedom movement of the upper platform will be realized in space. At present, there are many researches on six-degree-of-freedom measuring devices, such as: six-degree-of-freedom platform precision measuring mechanis...
