Phased array self-adaptive detection device and method suitable for rocket tank bottom welding joint detection

Abstract

The invention provides a phased array self-adaptive detection device and method suitable for rocket storage tank bottom welding joint detection. The phased array self-adaptive detection device comprises a phased array probe fixing plate 1, a phased array probe 2, a probe bracket 3, a phased array probe inner guide sleeve 4, a guide key 5, a phased array probe outer guide sleeve 6 and an elastic part. The phased array probe 2 is arranged on the phased array probe fixing plate 1; the phased array probe fixing plate 1 is connected with the probe bracket 3; one end of the phased array probe innerguide sleeve 4 is mounted on the probe bracket 3; the guide key 5 is arranged on the phased array probe inner guide sleeve 4; the elastic part is nested in the phased array probe inner guide sleeve 4;one end of the elastic part is in contact with the inner end surface of the phased array probe inner guide sleeve 4; and the other end of the elastic part is contacted with the inner end surface of the phased array probe outer guide sleeve 6. According to the invention, the requirements of high quality and high efficiency of product detection are met.

Description

technical field [0001] The invention relates to the technical field of detection of weld seams at the bottom of rocket tanks, in particular to a phased array adaptive detection device and method suitable for detection of weld seams at the bottom of rocket tanks. Background technique [0002] With the development of the times, the detection technology of the bottom ring seam and longitudinal seam of the rocket storage tank in my country has developed rapidly. At present, the latest phased array detection technology, due to its high detection accuracy and quality, has been used in my country's rocket tanks in recent years. Tank welding is widely used in the field of welding, but at present, manual hand-held detection is mostly used for the welding seam detection of rocket tanks, which not only greatly reduces the efficiency of detection, increases the labor intensity of workers, but is also easy to operate errors, which ultimately affects the entire efficiency of the welding pro...
