Description
Technical Field
The utility model belongs to the technical field of ultrasonic testing, concretely relates to unloading water logging ultrasonic testing device in automation for rod.
Background
The application and research of ultrasonic detection are carried out at the beginning of the 50 th of the 20 th century domestically. In recent 50 years, the ultrasonic detection technology in China has made great progress and development. At present, the method is not only applied to raw materials such as pipes, plates, rods and the like with regular shapes, but also applied to detection of parts with complex shapes and welding seams. The common ultrasonic detection is classified into portable manual detection and system automatic detection according to the manual intervention degree. The conventional bar with the diameter of 20 mm-70 mm is generally detected by water immersion ultrasonic manual detection, and the conventional bar with the diameter of 70 mm-100 mm is generally detected by contact ultrasonic manual detection. The manual detection coverage rate is low, the omission factor is high, and the labor intensity is high; the contact method has high noise and low sensitivity. Conditionally, the bar with the diameter of 20-100 mm is automatically detected by a water immersion ultrasonic system, and the automatic detection system is generally complex in device and high in cost.
With the rapid development of the industrial departments of metallurgy, chemical industry, aviation, aerospace, nuclear industry and the like, the ultrasonic automatic detection system is widely applied by the advantages of strong usability, high detection efficiency, good stability, high automation degree and the like.

For the bar with the diameter of 20-100 mm, the ultrasonic detection method by adopting the water immersion method is the most important and most effective nondestructive detection method for ensuring the product quality.
At present, the mature automatic detection mode of the system is suitable for batch production of factories, and for bars with the same specification, the detection system can be used until the bars are changed in specification after being calibrated, so that the labor intensity is low, the efficiency is high, and the stability is good. But the detection system has high investment cost in the early stage and long adjustment time before the detection of the bar. When the rods with small quantity, large specification and small length are encountered, a high-investment automatic detection system is not suitable, meanwhile, frequent replacement of the specification of the rods also requires a large amount of time for adjusting the detection system, and the rods with small length cannot be detected on the detection system.
