Hanging disc positioning method and hanging disc hanging method

Abstract

The invention relates to a hanging disc positioning method and a hanging disc hanging method. The hanging disc positioning method comprises the steps that a distance measuring piece is driven by a moving piece to move to at least three positions in sequence, the distance measuring piece obtains the distance between the distance measuring piece and the end face of an adapter at all the positions, a reference plane is defined by all the positions, the direction perpendicular to the positioning face of a visual positioning piece serves as the z direction, the reference plane is perpendicular to the z direction, and the measuring direction of the distance measuring piece is the z direction; if the distances measured at all the positions are not equal, an included angle alpha between the reference plane and the end face of the adapter is calculated according to the distances obtained at three positions and the side length of a triangle defined by the three positions; the visual positioning piece and the distance measuring piece are driven by the moving piece to rotate by alpha; the distance between the distance measuring piece and the end face of the adapter is obtained; an image of the end face of the adapter is acquired through the visual positioning piece; and the acquired data are compared with the position data of the hanging disc. The positioning method enables positioning to be more accurate.

Description

technical field [0001] The invention relates to the technical field of rail transit flaw detection, in particular to a method for locating an articulated disk and a method for articulated the articulated disk. Background technique [0002] The hollow axle is a key running part of rail transit rolling stock, and its operating state is directly related to the operation safety of rail transit rolling stock. According to the regulations of the National Railway Group, it is necessary to conduct regular flaw detection on the hollow axles of various rolling stock to ensure the safe operation of the rolling stock. In the related technology, the locomotives are usually parked in the motor vehicle service station, and the inspection personnel install the adapter on the hollow axle for the transitional connection between the hollow axle and the hollow axle ultrasonic flaw detection equipment, and then control the mobile hollow axle ultrasonic flaw detection equipment. The hitch plate ...

Problems solved by technology

In the above process, it is an important prerequisite for the subsequent flaw detection to accurately connect the mounting plate to the adapter. However, the current positioning method of mounting the mounting plate to the adapter cannot accurately obtain the relative position of the mounting plate and the adapter, which may lead to Failed to mount, need to repeat multiple mounts
