Embodiment Construction

[0021] The present invention will be further described below in conjunction with drawings and embodiments. In the following example, the self-collimating collimator is first placed on the left boresight of the large-span T-shaped turntable under test as an example.

[0022] Step 1: If figure 1 As shown, measure the height H1 of the reference plane of the reflector 5 after the tested T-shaped turntable 4 is placed on the indexing table 1 . Place the optical axis of the autocollimator 2 and the autocollimator theodolite 3 at the height of H1, and adjust the pitch of the autocollimator 3 to 90°, and at the same time adjust the azimuth and pitch of the autocollimator 2 so that the two observed The opponent's reticle is aligned with your own reticle. Among them, the autocollimation collimator 2 and the autocollimation theodolite 3 need to be basically at the same height, so as to ensure that the two can achieve alignment. The autocollimation theodolite 3 is adjusted to pitch 90°...

Abstract

The invention discloses an optical axis adjusting and calibrating method for a large-span T-shaped rotary table. An indexing table, an auto-collimation collimator and an auto-collimation theodolite are used to adjust the optical axis consistency of the large-span rotary table, and the method can also be used for detecting the parallelism at the same time. According to the method, small-caliber auto-collimation equipment can be used for achieving consistency adjustment and detection of the optical axis of the large-span rotary table, the span adjustment of the optical axis of hundreds of millimeters to several meters can be achieved, and the problems that use of a large-caliber collimator or multiple pentaprisms, rhombic prisms and the like for optical axis translation or beam expansion causes high machining difficulty, high cost and complex debugging methods are solved. The method is simple, effective, low in cost and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of optical instrument detection, and in particular relates to a method for adjusting the optical axis of a large-span T-shaped turntable. Background technique [0002] At present, the photoelectric turntable is widely used, and its accuracy and performance requirements are getting higher and higher. The parallelism of the optical axis between the multi-sensors of the photoelectric turntable is crucial to its accuracy and performance, but the distance between the optical axes of the T-type turntable multi-sensors is several It is very difficult to adjust the parallelism of the optical axis of the large-span T-shaped turntable from one hundred millimeters to several meters. A simple method for adjusting the parallelism of the optical axis of the large-span T-shaped turntable is important for improving the accuracy and performance of the T-shaped turntable. significance. [0003] In the existing patents and do...
