Three coordinate converting machine for integrated testing of quality characteristics

Abstract

The invention discloses a three coordinate converting machine for integrated testing of quality characteristics. An arc substrate is provided with an arc surface matched with arc guide rails, and a horizontal plane used for fixedly mounting the arc substrate; two arc guide rails are respectively arranged on the arc surface of the arc substrate, and arc sections of the arc guide rails are parallel to an arc section of the arc substrate; a slipway is arranged on the arc guide rails and slides along the arc guide rails under the action of a driving mechanism; the slipway can rotate along the normal direction of each point of the arc sections of the arc guide rails; the driving mechanism is arranged in the arc substrate; and a workpiece to be tested is arranged on the slipway, and the automatic conversion between quality characteristic parameters of the workpiece to be tested at a vertical position under Cartesian coordinates and quality characteristic parameters of the workpiece to be tested at any position under the Cartesian coordinates is realized through the movement of the slipway on the arc guide rails. The three coordinate converting machine has simple structure and convenient operation, and can be used for integrated testing of the quality characteristics of large equipment such as spacecrafts and the like.

Description

technical field [0001] The invention relates to a three-coordinate conversion device for automatic conversion of the positional relationship between the coordinate system of a measured piece and the coordinate system of a test bench, which is applied to the quality characteristic test of a spacecraft. Background technique [0002] With the rapid development of aerospace technology, there are more and more types of spacecraft, and the development cycle is continuously shortened. Therefore, the quality characteristic test of spacecraft is an indispensable and important index parameter in the development of spacecraft, and its test time and accuracy will occupy an important position in the development of high-precision spacecraft. [0003] The quality characteristic test of spacecraft involves the conversion and testing between the spacecraft body coordinate system and the test bench coordinate system. How to realize the mass characteristic integration test and coordinate tran...
