Embodiment Construction

[0026] Such as Figure 5 , 6 As shown, the precision orthogonal shaft system to be tested is set on the detection platform, and the four-dimensional adjustable reticle is installed on the rotating link of the pitching part of the precision orthogonal shaft system to be tested through the adapter plate. The focusing autocollimator in the TV Placed directly in front of the four-dimensional adjustable reticle, it is used for self-alignment and aiming at the reticle.

[0027] Such as figure 1 , 2 As shown, the TV internal focusing autocollimator is composed of an internal focusing optical system, a CCD image sensor imaging system, an operation control system mounting seat and the like. Panel operation instructions: "Switch" operation performs limit, X and Y conversion; "Lighting" operation adjusts the brightness of LED lighting, a total of 5 levels of brightness adjustment; "Reset" adjusts the working distance to the parallel light position at the limit, X and Y It is used for...

Abstract

The invention relates to a system and method for detecting the orthogonality of a precision shafting. The detection system comprises a four-dimension adjustable reticle, a television interior focusing autocollimator, and a detection platform. The four-dimension adjustable reticle is mounted on a rotating link of a pitch component of a to-be-detected precision orthogonal shafting. The detection platform is used for supporting the to-be-detected precision orthogonal shafting. The television interior focusing autocollimator is used for working with the four-dimension adjustable reticle to detect the orthogonality of the shafting through autocollimation and collimation. The four-dimension adjustable reticle is mounted on the rotating link of a shafting, the mirror surface of the reticle is adjusted to be perpendicular to the axis, the reticle center is on the axis, and the axis is simulated with the aid of the center of the reticle in the detection process rather than the center of a process hole. The limitations and defects of the prior art are overcome. After one adjustment, both the verticality and the intersection deviation can be obtained. The system and the method of the invention are based on the optical principle. The detection accuracy and efficiency are high. The method is simple. No requirement is put on the machining precision of a process hole in a bearing sleeve. The system and the method are easy to implement.

Description

technical field [0001] The invention belongs to the technical field of detection of precision machinery orthogonal shafting, and relates to a detection system and method for the orthogonality of precision shafting. Background technique [0002] With the continuous development of photoelectric system comprehensive technology, high-precision steady aiming technology and high-precision transmission system have become an inevitable trend of development at this stage. In order to ensure that the photoelectric system can accurately capture, aim and track targets, the positive Intercourse has put forward very high index requirements. [0003] The Chinese patent application with the application number 201010241206.5 "A Method for Testing the Perpendicularity and Position of Orthogonal Shafts" discloses a detection method for detecting the orthogonality of precision When one of the shaft systems is a structure composed of two half-shaft parts, and the design process holes of the bea...
