Micro-pipe internal flaw and appearance measurement device and method

Abstract

The invention relates to micro-pipe internal flaw measurement and optical measurement. The invention provides a micro-pipe internal flaw measurement and appearance measurement device and a method, having the performance characteristics of flexibility, automation, rapidness, online and the like, so as to meet the measurement requirements of modern industry on small size feature inner bore or micro-pipe internal flaw and appearance. For achieving the purposes, the invention adopts the technical scheme that: the micro-pipe internal flaw measurement and appearance measurement device comprises a micro-pipe internal flaw measurement and appearance measurement sensor, wherein the sensor consists of an optical transmission part, a lighting source and a camera; the sensor is fixedly connected with a tail end joint of an industrial robot; pipe internal 360-degree cylindrical surface annular panoramic picture data is transmitted by the optical transmission part, shot by the camera and is collected by an image acquisition card to be processed by a computer. The micro-pipe internal flaw measurement and appearance measurement device and the method are mainly applicable to micro-pipe internal flaw measurement.

Description

technical field [0001] The invention relates to defect measurement and optical measurement in a micro-pipeline, in particular to a device and method for measuring the defect and shape in a micro-pipeline. Background technique [0002] With the development of advanced manufacturing and science and technology, micro-pipes or small-sized characteristic inner holes are more and more widely used in aerospace, automotive, energy, metallurgy, chemical and other fields, such as the control of aerospace vehicle heat dissipation and airflow field Pipelines, automobile engine block, cylinder head and gearbox, heat exchange tubes and condensers of nuclear reactors and steam generators, as well as reaction kettles and reaction towers in chemical applications, are distributed with a large number of microscopic pipes with complex shapes or small-scale features Bore. During the precision casting process of the above-mentioned components or devices, due to the existence of dust or air gaps,...

AI Technical Summary

Problems solved by technology

However, the use of endoscopes can only qualitatively determine whether there are defects such as flaws and cracks on the inner surface of the pipeline, but cannot quantitatively give the size and specific location of the defects, especially manual operation is required, so the application has great limitations

In addition, the existing methods for the detection of micro-pipes or hole walls still have disadvantages such as low precision, slow detection speed, and low degree of automation, which cannot meet the actual production needs of flexible, automated, and rapid detection.
