Wheel disc type laser calibrator

Abstract

The invention relates to the technical field of laser calibrators, and particularly relates to a wheel disc type laser calibrator which comprises a base, a shell and a scale plate. A positioning cylinder is fixedly connected to the top of the base, a bearing is fixedly connected to the interior of the top end of the positioning cylinder, and the positioning cylinder is rotatably connected with a ball screw through the bearing arranged in the top end of the positioning cylinder; and the surface of a nut of the ball screw is fixedly connected with a driven gear. The calibrator has the advantages that light emitted by first laser emitters and second laser emitters is used for replacing a plumb bob and a thin rope, the calibrator is not affected by weather, the collimation of reference lines is guaranteed, the accuracy is high, the distance between the three second laser emitters is 15 mm, during calibration, the left and right 15-mm reference lines can be provided for calibration, the equipment does not need to move leftwards or rightwards, errors generated in the process of moving leftwards by 15 mm or moving rightwards by 15 mm in a traditional method are avoided, meanwhile, the beneficial effects of saving time and labor are achieved, and the overall automation degree of the equipment is high.

Description

technical field [0001] The invention relates to the technical field of laser collimators, in particular to a wheel-type laser collimator. Background technique [0002] At present, the army adopts the traditional "straight rope method" for the calibration of the course mark, that is, first level the aircraft, and calibrate the zero position of the bias current and the zero position of the dragging sight. Using the plumb method, hang two plumbs at the measurement points of the aircraft axis respectively, project the two points onto the ground, and move them to the left by 15mm, use a 3mm string to pass through the two points after translation, and mark a line parallel to the axis of the aircraft Straight line, and extend 25m forward at the 15mm left side of the straight line, and then pull the string tightly. The straight rope is used as the calibration reference line of the bombsight heading mark, and the on-board calibration of the heading mark is performed through this ref...

Problems solved by technology

[0003] 1. Affected by the wind force, the connection between the plumb line and the axis measurement point may not be perpendicular to the ground, resulting in a deviation in the projection point. Due to the influence of weather and other factors such as the toughness of the string, the alignment of the string is not enough to reflect the real the longitudinal axis of the aircraft;

[0004] 2. The vertical projection may not coincide with the longitudinal axis of the aircraft after being moved, resulting in errors in the thin rope as a reference line
