Abstract

The invention provides a device and a method for testing comprehensive pointing precision of a rotary table. The device comprises a parking table and a parallel light source, the parking platform is used for parking the tested turntable; and the parallel light source is imaged in the camera on the tested turntable. According to the test device and method, the comprehensive pointing precision of the rotary table under the rated working condition can be tested and evaluated, and the change rule of the comprehensive pointing precision and the phase is obtained.

Description

technical field [0001] The invention relates to the technical field of pointing accuracy testing of a mechanical turntable, in particular to a test device and method for comprehensive pointing accuracy of a turntable. In particular, it preferably relates to a test device and method for comprehensive pointing accuracy of a two-dimensional turntable. Background technique [0002] The comprehensive pointing accuracy is an important index to measure the performance of the two-dimensional turntable. It provides the initial attitude of the stand-alone machine it carries, and is one of the key factors for whether the stand-alone machine can accurately reach the designated position. In order to ensure the necessary precision when working alone, it is necessary to evaluate and control the comprehensive pointing precision when developing a two-dimensional turntable. [0003] At present, the evaluation method for the comprehensive pointing accuracy of the two-dimensional turntable mos...
