AI Technical Summary

Technical Problem

The existing high-frequency welded pipe inspection methods are outdated and cannot achieve full-circumference automatic scanning and high-precision non-contact inspection, resulting in high missed detection rate, low efficiency, and large human error, making it difficult to meet the quality control requirements of the production line.

Method used

The system uses a three-jaw chuck to drive the rotation of the welded pipe, combined with the linkage design of multiple sets of support wheels and clamping wheels, and a laser displacement sensor to perform 360° continuous scanning, to achieve automated, non-contact measurement of the welded pipe. The controller is used for data acquisition and judgment.

Benefits of technology

It achieves high-precision detection (±0.01mm) of welded pipe outer diameter and ovality, reduces detection time to less than 1 minute, supports online continuous detection, avoids blind spots and errors of manual detection, and improves detection efficiency and accuracy.

Abstract

The utility model discloses a high-frequency welded pipe outer diameter shaping inspection device which comprises a detection platform, a chuck driving assembly, at least two supporting assemblies, a pressing assembly, a detection assembly and a controller. The chuck driving assembly clamps the end of the welded pipe through a three-jaw chuck and is driven by a driving mechanism to rotate. The supporting assembly is fixed on the platform to support the pipe body; the pressing assembly presses pressing wheels downwards through a lifting driving piece and a hinge support and cooperates with the supporting wheels to limit the welded pipe. The detection assembly adjusts the position of the displacement sensor through the sliding table module and aligns to the suspended section of the welded pipe for non-contact scanning. According to the device, high-precision outer diameter and ovality detection under full-circumference automatic rotation of the welded pipe is realized, the precision reaches + / -0.01 mm, the single-pipe detection time is less than or equal to 1 minute, and the problems of low efficiency and high omission ratio of traditional manual detection are solved.
