Abstract

The invention discloses a flange pipeline end measuring method, a measuring device and an adapter structure, and the method comprises the steps: collecting an image of an adapter with a mark point through a calibrated multi-camera measuring system, building an adapter coordinate system, and determining the positions of the end surface and the axis of the adapter in the adapter coordinate system; inserting an adapter into a flange hole in the end of the flange pipeline; collecting an image of the adapter, and determining a coordinate value of the mark point in a world coordinate system; determining a coordinate system conversion relationship according to the coordinate values of the mark points in the adapter coordinate system and the world coordinate system; according to the positions of the end face and the axis of the adapter in the adapter coordinate system, determining the positions of the end face and the axis of the flange hole in the world coordinate system based on the conversion relation; collecting an image of the flange pipeline, obtaining the position of the central axis of the flange pipeline, and determining the position relation of the flange hole relative to the central axis of the flange pipeline. The position relation of the flange hole site relative to the flange pipeline end can be accurately measured.

Description

technical field [0001] The invention relates to pipeline detection, in particular to a method for measuring a flange pipeline end, a measuring device and an adapter structure. Background technique [0002] At present, the pipeline system is widely used in aviation, aerospace, automobile and other industrial fields. Whether it can be assembled accurately will directly affect the quality of the product, so the inspection of the pipeline is particularly important. As one of the core components of the pipeline, the pipe end is affected by the process and often has machining errors. Therefore, it is necessary to accurately ensure the center position of the end faces of the joints at both ends of the pipeline during the assembly process. Only the pipelines that have passed the inspection can be assembled, so as to control the product quality. The existing technologies for measuring the spatial position parameters of the pipeline end mainly include three coordinate measuring machi...
