Abstract

The invention discloses an ultrasonic transducer which comprises a front cover plate, a back cover plate and a prestressed bolt. A piezoelectric ceramic piece and a conductive pole piece are arrangedbetween the front cover plate and the back cover plate; a first inner screw hole is formed in the back end surface of the front cover plate; through holes are formed in the back cover plate, the piezoelectric ceramic piece and the conductive pole piece; a screw rod of the prestressed bolt penetrates through the through holes so as to be fixedly connected with the first inner screw hole of the front cover plate; the front cover plate outwards extend to form a flange structure along the radial direction from the periphery of the front cover plate; a circumferential inner wall surface is arrangedon the flange structure; a flange inner screw thread is arranged on the circumferential inner wall surface; and a spring washer is arranged between the back end surface of the back cover plate and ascrew cap of the prestressed bolt. Compared with an existing design, the ultrasonic transducer has the advantages of simple structure, easiness in implementation, low implementation cost, uniformity in internal stress, high electro-acoustic conversion efficiency, long service life, simple structure, flexibility, good stability, less outward transmission vibration, high performance stability and the like which are not possessed by existing similar products.

Description

technical field [0001] The invention relates to products in the field of ultrasonic applications, in particular to an ultrasonic transducer. Background technique [0002] High-power ultrasonic transducers are widely used in fields such as plastic welding, metal welding and cleaning. High-performance ultrasonic transducers are at the heart of these applications. Sandwich ultrasonic transducers are widely used to generate longitudinal vibration due to their simple structure. [0003] Longitudinal vibration ultrasonic transducers usually consist of a front cover, a piezoelectric ceramic sheet, a metal conductive electrode, a rear cover and prestressed bolts for locking the above components. The design of the front cover determines the output of the ultrasonic longitudinal vibration and thus has a huge impact on the overall performance of the ultrasonic transducer. The front cover in many ultrasonic transducers is prone to cracks due to design flaws. [0004] Usually, the ul...
