Embodiment 1

[0039] like Figure 1-5 As shown, the steel pipe surface defect detection device includes a steel pipe idler mechanism, a steel pipe 2, a camera movement control mechanism, a camera 4, a steel pipe clamping and rotating mechanism, and a main control computer 6.

[0040] The steel pipe idler mechanism includes a roller 11 , a bearing seat 12 , a slide rail 13 and an electromagnet 14 . The number of rollers 11 is two, and the two rollers 11 are arranged parallel to each other and horizontally, and the two ends of the rollers 11 are movably installed on the supporting base 12 through bearings. The slide rail 13 is fixedly installed on the ground, and is located at the lower end of the support base 12, and is slidingly matched with the support base 12. The electromagnet 14 is embedded in the bottom of the support seat 12 and faces the slide rail 13. When the electromagnet 14 is energized, the support seat 12 and the slide rail 13 are fixed as one. When the electromagnet 14 is pow...

Abstract

The invention discloses a steel pipe surface defect detection device and method and relates to the technical field of pipe detection. The steel pipe surface defect detection device comprises a steel pipe carrier roller mechanism, a steel pipe, a camera movement control mechanism, a camera, a steel pipe clamping and rotating mechanism and a main control computer. A steel pipe surface defect detection method is applied to a steel pipe surface defect detection device and comprises the following steps of 1, presetting items; 2, segmenting the steel pipe; 3, clamping the steel pipe; 4, acquiring a steel pipe surface image; and 5, comparing the images. The steel pipe surface quality detection device can replace manual work for steel pipe surface quality detection and is suitable for surface quality detection of different pipe diameters, different lengths and different detection precision requirements. Compared with manual detection, detection efficiency is higher, and the error and leakage detection rate is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of pipe detection, in particular to a detection device and a detection method for steel pipe surface defects. Background technique [0002] The surface quality of the steel pipe is an important index to evaluate the steel pipe grade, and the quality of the steel pipe surface quality will directly affect the quality and performance of the product. [0003] However, in the process of producing steel pipes, due to various reasons such as site environment and equipment, it is inevitable that there will be scratches, roll marks, cracks, inclusions, rust spots, pits, pockmarks, abrasions and other types of defects on the surface of steel pipes. . These defects not only affect the appearance of the product, but also reduce the performance of the product. [0004] At present, most steel pipe production enterprises arrange inspectors to detect surface defects of steel pipes online. On the one hand, the efficiency o...
