Background

In the steel pipe production and processing industry, quality detection of finished steel pipes is a key link for ensuring that products meet standard requirements. Currently, the detection of steel pipes generally covers multiple dimensions, including but not limited to the accuracy of the outer diameter, the smoothness of the inner diameter, and the surface gloss, which directly relate to the performance and appearance quality of the steel pipe. Traditionally, these test items have been performed by means of a single hand-held test device, often requiring separate operating steps and specialized test tools for each test item.

With the continuous progress of steel pipe manufacturing technology, especially the application of long-size and large-caliber steel pipes is increasingly wide, the existing handheld detection equipment exposes significant problems in actual operation. Specifically, for longer steel pipes with larger weight, the handheld detection mode is poor in stability, so that measurement errors are easily caused by hand shake or inaccurate positioning in the detection process, and the accuracy and reliability of the detection result are further affected. In addition, the efficiency is low by replacing different detection devices for many times, the labor intensity of operators is increased, and the continuous operation and the cost control of the production line are not facilitated.

Therefore, research and development of a multifunctional clamp capable of firmly clamping steel pipes with different specifications and facilitating multi-dimensional detection of outer diameter, inner diameter, glossiness and the like is a technical problem to be solved urgently by those skilled in the art.
