Automatic flaw detector for detecting pipeline type part

Abstract

The invention relates to the technical field of ultrasonic detection, in particular to an automatic flaw detector for detecting a pipeline type part. The detector comprises a detection bed, a detection probe, a detection bin, a servo guide rail module, a pipeline limiting seat and two groups of pipeline rotating mechanisms which are arranged in parallel. The pipeline rotating mechanisms are arranged along the left and right direction of the detection bin. The pipeline rotating mechanisms comprise U-shaped seats, rotating wheels, wheel shafts and gear motors, at least four pipeline limiting seats are arranged in the front-back direction of the detection bin in a rectangular array mode, the pipeline rotating mechanisms are arranged among the four pipeline limiting seats, the sides, facing the pipeline rotating mechanisms, of the pipeline limiting seats are inclined, and the pipeline type part thereof is arranged among the pipeline limiting seats; the side wall of the pipeline type part makes contact with the rotating wheels and the inclined faces of the pipeline limiting bases, and the center line of the pipeline type part is parallel to the center lines of the wheel shafts. The equipment has the functions of automation, higher reliability, capability of realizing preliminary quantification of defects and higher detection efficiency.

Description

technical field [0001] The invention relates to the technical field of ultrasonic detection, in particular to an automatic flaw detection machine for detecting pipeline parts. Background technique [0002] Ultrasonic testing is to use the principle of reflection, transmission and refraction of ultrasonic waves to detect defects in materials when they encounter heterogeneous sections (abnormal areas) during work. The ultrasonic wave has the characteristics of good directionality, strong penetrating ability, and high energy. When it encounters an interface, it will produce reflection, refraction, and wave mode conversion, and it is harmless to the human body. Therefore, the advantages of ultrasonic testing are: ①It is suitable for the detection of internal defects of the workpiece, with high detection sensitivity, and can find small defects, especially sensitive to planar defects; ②After adjusting the vertical linearity and horizontal linearity of the instrument, a relatively ...

Problems solved by technology

[0004] In the current detection technology, because the pipeline is fixed, only the detection head moves, and the two cannot cooperate perfectly, so that the pipeline-type parts undergo a full-body inspection, which results in partial missed inspection of the part, and cannot fully guarantee the integrity of the entire pipeline-type parts. overall quality
