Abstract
An electromagnetic ultrasonic double wave transducer, comprising a shell (), and a permanent magnet assembly, a coil (), a shielding layer (), and a wire () which are provided in the shell (). The permanent magnet assembly comprises a first permanent magnet () and a second permanent magnet () sleeved on the first permanent magnet (). The magnetizing directions of the first permanent magnet () and the second permanent magnet () are perpendicular to the bottom of the shell (), and the magnetic field directions of the first permanent magnet () and the second permanent magnet () are opposite. A non-conducting non-magnetic bushing material () is provided between the first permanent magnet () and the second permanent magnet (), and upper end faces of the first permanent magnet () and the second permanent magnet () realize magnetic circuit closing by means of a magnetic circuit closing element (). The coil () is fixed on the bottom of the shell () and is located below the first permanent magnet (). The shielding layer () is provided between the lower end of the first permanent magnet () and the coil () and below the second permanent magnet (). One end of the wire () is connected to the coil (), and the other end is connected to the power supply and signal plug (). The electromagnetic ultrasonic double-wave transducer can simultaneously stimulate longitudinal wave and transverse wave on the surface of the part to be inspected, and the inspection accuracy is improved.
