The piezoelectric ceramics, the inner aluminum sleeve and the outer aluminum sleeve are provided with upper pressing sleeves and lower pressing sleeves, the upper pressing sleeves and the lower pressing sleeves are provided with inner convex edges corresponding to the inner side of the inner aluminum sleeve and outer convex edges corresponding to the outer side of the outer aluminum sleeve, the upper end and the lower end of an ultrasonic transduction pipe main body are respectively sleeved with the upper pressing sleeves and the lower pressing sleeves, and the inner convex edges and the outer convex edges of the upper pressing sleeves and the lower pressing sleeves respectively clamp the inner side of the inner aluminum sleeve and the outer side of the outer aluminum sleeve. The piezoelectric ceramics are pressed in the radial direction through the inner aluminum sleeve and the outer aluminum sleeve, 360-degree comprehensive radiation is achieved, limitation on the size of a transducer is reduced, and the transducer is more stable in integral structure due to the arrangement of the upper pressing sleeves and the lower pressing sleeves.
Description
Technical field
The utility model relates to a kind of ultrasonic wave transducer pipe.
Background technology
Conventional ultrasonic wave energy converting pipe, comprise the aluminum casing being arranged on above mass, liner copper pipe is fixedly embedded in the piezo tube of aluminum casing inner side, install the brilliant heap of connector and piezoelectric ceramics additional on aluminum casing top, the brilliant heap of described mass, aluminum casing, connector and piezoelectric ceramics is fixedly connected with by the prestressing force screw rod that runs through center.The brilliant heap of piezoelectric ceramics is made up of the identical piezoelectric ceramic wafer of multiple structures.Prestressing force screw rod runs through mass, liner copper pipe, piezo tube, aluminum casing, connector and piezoelectric ceramics Jing Dui center, and upper/lower terminal is separately fixed at the outboard end of the brilliant heap of piezoelectric ceramics and mass by nut.After crystalline substance heap making alive, produce extensional vibration, thereby cause the extensional vibration of thin pipe, the extensional vibration of pipe is converted into radial vibration, thereby the radial displacement of pipe is increased, and the transmitting power of transducer is increased.But there is following defect in this ultrasonic wave transducer pipe: 1, can only realize the single degree of freedom direction radiation of excusing from death energy, cannot be comprehensive 360 degree radiation; 2, the diameter of transducer is subject to larger restriction; 3, the vibration velocity of transducer and vibration displacement are larger.
Summary of the invention
In view of the deficiency of background technology, technical problem to be solved in the utility model is to provide one can realize that Omnidirectional radiation and vibration velocity and displacement are less, the better ultrasonic wave transducer pipe of stability.
For this reason, the ultrasonic wave transducer pipe that the utility model provides, comprise piezoelectric ceramics, interior aluminum casing and outer aluminum casing, described piezoelectric ceramics is cannula-like, piezoelectric ceramics has at least three and diameter to become gradually large, at least three mutual close-fitting sockets of piezoelectric ceramics, between at least three piezoelectric ceramics interior aluminum casing and outer aluminum casing in mutual socket, interior aluminum casing and outer aluminum casing have pretightning force and compress electroceramics, described piezoelectric ceramics, interior aluminum casing and outer aluminum casing dispose clamping sleeve and lower clamping sleeve, upper clamping sleeve and lower clamping sleeve are all with the interior convex edge of the medial surface corresponding to interior aluminum casing and the outer convex edge of outer aluminum casing lateral surface, described upper clamping sleeve and lower clamping sleeve are enclosed within respectively the two ends up and down of ultrasonic wave transducer tube body, and the He Wai convex edge, interior convex edge of described upper clamping sleeve and lower clamping sleeve is clamped in respectively the medial surface of interior aluminum casing and the lateral surface of outer aluminum casing.
In the utility model, by interior aluminum casing and outer aluminum casing radial compaction piezoelectric ceramics, realize 360 degree Omnidirectional radiations, reduce the restriction to transducer dimensions, make transducer overall structure more firm by the setting of upper clamping sleeve and lower clamping sleeve simultaneously.
