Embodiment Construction

[0037] The present invention is described in detail below in conjunction with accompanying drawing:

[0038] First build as figure 1 The spatial coordinate system shown in the figure defines the horizontal, vertical and vertical directions of the space. In the spatial coordinate system, the direction pointed by the arrow is the positive direction, and the direction facing away from the arrow is the negative direction. The lower end of the six-degree-of-freedom measurement system B is installed horizontally on the connecting beam 17 , and the upper end is connected to the connecting disc 30 .

[0039] refer to figure 2 , the calibration device of the six-degree-of-freedom measurement system of the present invention is composed of a frame rail assembly 1 , a two-axis sliding assembly 2 and an angular displacement measurement connection assembly 3 . The two-axis sliding assembly 2 is slidingly connected to the frame guide rail assembly 1 through the transverse slider 15, and t...

Abstract

The invention relates to a calibration device of a six-freedom-degree measurement system. With the calibration device, a problem that the existing spatial six-freedom-degree measurement device can not be calibrated rapidly can be solved. The calibration device comprises a frame guide rail assembling body (1), a two-shaft sliding assembling body (2), and an angle displacement measurement assembling body (3). On the basis of the orthogonal measuring way, the provided calibration device that has advantages of low cost, high detection precision, simple and convenient operation, small accumulated error, and reliable performance and is capable of meeting a calibration error range is provided.

Description

technical field [0001] The invention relates to a calibration device for a space displacement measuring device, more specifically, it relates to a calibration device for a six-degree-of-freedom measurement system. Background technique [0002] With the development of the existing industry, military, national defense and aerospace industries, it is required to be able to quickly measure the space motion attitude of objects to complete the requirements of the test. 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. Scholars at home and abroad also have research on six-degree-of-freedom measurement platforms, most of which are six-degree-of-freedom measurement devices based on the Stewart structure, but ...
