The detection device comprises a supporting frame, a first rotating shaft and an optical target assembly; the supporting frame is of a semicircular structure, and the bottom of the supporting frame isfixedly connected with the first rotating shaft; the first rotating shaft can drive the supporting frame to rotate; the optical target assembly comprises a plurality of parallel light pipes, the parallel light pipes are evenly arranged on the supporting frame, the optical axes of all the parallel light pipes are located in the same plane, and the optical axes of all the parallel light pipes intersect at the circle center of the supporting frame. When the detection device is used for detecting an optical theodolite or an aviation airborne optical platform, the first rotating shaft can drive the supporting frame to rotate around the detection optical theodolite or the aviation airborne optical platform, so that dynamic detection and static detection are combined, multiple technical indexescan be detected on one detection device, and detection data are comprehensive. In addition, the invention also provides a photoelectric theodolite detection system and an aviation airborne optical platform detection system.

Multi-joint robot geometric dimension accuracy calibration device and method based on standard gauge
PendingCN109108982ACalibrate geometric dimension accuracyReal-time calibration of geometric dimension accuracyProgramme-controlled manipulatorEngineeringGauge block
The invention relates to a multi-joint robot geometric dimension accuracy calibration device and method based on a standard gauge, and belongs to the technical field of high-precision detection. The multi-joint robot geometric dimension accuracy calibration device comprises a dial indicator and a standard gauge block. The dial indicator is rigidly connected with a flange plate at the tail end of arobot. The standard gauge block is fixed to a workbench. The top end of the dial indicator fixed to the flange plate at the tail end of the robot is perpendicular to a surface to be detected by the standard gauge block, but does not make contact with the surface to be detected by the standard gauge block. The invention further provides a calibration method used for calibrating the geometric dimension of a mechanical arm of a robot through the calibration device. By adoption of the device and method, the simple dial indicator and the simple standard gauge block are used for detecting relativeerrors of the tail end of the robot, so that the influences of accumulative errors are avoided, and changes, caused by variations of the environmental temperature, of the geometric dimension of the robot are compensated; and the method can achieve detection based on analysis in three directions in a three-dimensional spatial coordinate system, so that detection data are more comprehensive.
