Abstract

The invention discloses a spiral welded pipe line outer diameter measuring device and method based on double visual sensors. The device comprises a measuring platform. A guide rail is arranged on themeasuring platform. Four sliding blocks capable of moving back and forth along the guide rail are arranged on the guide rail. Two sliding blocks are located on one side of a measured spiral welded pipe, and the other two sliding blocks are located on the other side of the measured spiral welded pipe. For the two sliding blocks at the same side, one sliding block is equipped with a visual sensor, and the other sliding blocks is equipped with a laser generator. The central optical axes of the two vision sensors both have at an angle to the center line of the guide rail. A laser plane generated by the two laser generators is parallel to the center line of the guide rail. The surface of a target is perpendicular to the center line of the guide rail.

Description

technical field [0001] The invention belongs to the technical field of spiral welded pipe diameter measurement, and relates to a device and method for measuring the outer diameter of a spiral welded pipe pipeline based on dual vision sensors. Background technique [0002] With the trend of "large diameter, thick wall and high steel grade" in domestic and foreign pipeline construction, large diameter spiral welded pipe is more and more widely used, and its proportion has been increasing. In the spiral welded pipe production industry, the diameter of the steel pipe is required to be measured during the forming stage to ensure product quality. At present, the commonly used pipe diameter measurement method in enterprises is manual measurement, that is, measurement with a tape measure. This measurement method has the following shortcomings: the degree of automation is low; the measurement results are greatly affected by human factors; only the average value of the steel pipe dia...
