Measurement and mounting method of target spots on plane calibration target plate

Abstract

The invention relates to a measurement and mounting method of target spots on a plane calibration target plate. The adopted technical scheme comprises the following steps: aligning a platform core to serve as a symmetry axis of a plane on a framework; aligning plane surfaces of a plurality of curved plates through a levelling ruler, and fixing the coplanar curved plates on the platform; vertically placing the framework as a whole on the platform and fixing on the curved plates through cramp frames; gluing processing pieces on a vertical axis of a vertical shaft so as to determine the position of a marker line for the symmetry axis of the plane on the framework; aligning the perpendicularity of the framework through measuring the center line of the processing piece by a theodolite, and aligning the horizon of the left and right frameworks through a level meter and a height ruler; and measuring the positions of all target spots through the height ruler and a block gage, gluing the target spots on the framework through a 502 glue after the completion of measurement, forming drill holes in the framework according to holes in the target plate, and fixing the target plate on the framework through bolts. The target plate prepared by the invention can ensure measurement and mounting precision of the target spots, as a result, the precision of the whole calibration target plate is met, and utilization requirements of the plane is met.

Description

technical field [0001] The invention relates to a method for installing a target board, in particular to a method for measuring and installing a target on a calibration target board used as a measurement reference for an aircraft in a horizontally parked state. Background technique [0002] The ground support equipment calibration target board is used as a measurement reference to measure their actual coordinates on the aircraft when the aircraft is parked horizontally and uses the calibration mirror to calibrate the airborne equipment. Then, the airborne equipment is corrected according to the measured value in actual use. It can be applied to multi-type aircraft, and its structure is supported by a tripod placed on the ground. Aluminum frame, on the aluminum frame, according to the purpose and requirements of different aircraft, determine the horizontal reference line of the aircraft and the marking line of the aircraft symmetry axis. Then install different positions, dif...

Problems solved by technology

But its disadvantage is that it is very laborious to align the frame horizontally and vertically, the accuracy is poor, and the frame cannot be fixed between the contour block and the platform, and the frame is easy to move during the measurement and installation process and affect the target point. The most important thing is that the installation state is different from the use state, and the measurement reference is different. After the target is installed in a horizontal state, when the frame is erected, the overall accuracy will be affected due to the misalignment of the reference
