It has a wide range of applications in many industrial and medical applications. The core component of an ultrasonic transducer is usually a piezoelectric ceramic sheet. The piezoelectric effect refers to that when an electric field is applied, the piezoelectric material will undergo dimensional changes, thereby generating mechanical motion or sound waves. This property of the material makes it possible to be used as an element for emitting and receiving sound waves. During the airtightness detection process of an ultrasonic transducer, a clamping tooling is usually required for fixation.

[0003] In the prior art, during the use of an ultrasonic transducer clamping tooling, a cylinder is usually used to drive a clamping plate to fix the ultrasonic transducer, and then the ultrasonic transducer is sealed up and down, and gas is injected, and the change of the pressure gauge is observed to detect whether there is a leakage situation. However, multiple sets of driving devices need to be used in cooperation during the whole detection process, and the operation process is relatively cumbersome, which affects the detection efficiency of the airtightness of the ultrasonic transducer.

[0029] Please refer to Figures 1-5 , the present utility model is an improved structure of an ultrasonic transducer assembly tooling, including a detection table 1. A detection groove 2 is opened at the top of the detection table 1. An ultrasonic transducer body 3 is arranged at the top of the detection groove 2. Clamping plates 4 are arranged on both sides of the ultrasonic transducer body 3; A driving assembly is arranged at the top of the detection table 1. The driving assembly includes a hydraulic rod 5. The hydraulic rod 5 is arranged at the top of the detection table 1. The output end of the hydraulic rod 5 is fixedly connected with a pressure pipe 6. A pressure plate 7 is arranged at the bottom of the pressure pipe 6. Push rods 8 are fixedly connected to both sides of the pressure plate 7.

The pressure detection assembly includes a piston piece 10. The piston piece 10 is slidably connected inside the pressure pipe 6. An air delivery pipe 11 is communicated with the top of the pressure pipe 6.

[0030] Specifically, a gasket is fixed inside the detection groove 2. After the ultrasonic transducer body 3 is inserted into the detection groove 2, the sealing performance at the bottom of the ultrasonic transducer body 3 can be maintained. A rubber pad is installed inside the clamping plate 4, which can buffer the clamping process of the ultrasonic transducer body 3. The push rod 8 is in contact with the surface of the push block 9. When the push rod 8 moves downward, the push block 9 can be pushed to adjust the position of the clamping plate 4. The piston piece 10 is slidably connected to the inner wall of the pressure pipe 6. By moving the piston piece 10 up and down, the air inside the pressure pipe 6 can be compressed. Specific Embodiment Two

[0032] Please refer to Figures 1-5 , on the basis of Specific Embodiment One, a sealing plug 12 is fixedly connected to the surface of the air delivery pipe 11. A support column 13 is fixedly connected between the sealing plug 12 and the pressure pipe 6. The pressure detection assembly further includes a detection pipe 14. The detection pipe 14 communicates with the bottom of the detection table 1. The other end of the detection pipe 14 communicates with a pressure gauge 15. A first electromagnetic valve 16 is sleeved on the surface of the detection pipe 14. A second electromagnetic valve 17 is sleeved on the surface of the air delivery pipe 11. A vertical rod 18 is fixedly connected to the bottom of the sealing plug 12. The bottom of the vertical rod 18 penetrates through the pressure pipe 6 and is fixedly connected to the pressing plate 7. A first spring 19 is sleeved on the surface of the vertical rod 18. The top and bottom ends of the first spring 19 are respectively fixedly connected to the pressure pipe 6 and the pressing plate 7. A sliding rod 20 is fixedly connected to the top of the detection table 1. A second spring 21 and a moving plate 22 are respectively sleeved on the surface of the sliding rod 20. The rear side of the moving plate 22 is fixedly connected to the push block 9. A support 23 is fixedly connected to the surface of the hydraulic rod 5. The bottom of the support 23 is fixedly connected to the detection table 1.

[0033] Specifically, the sealing plug 12 is made of rubber. When the sealing plug 12 moves downward and inserts into the top of the ultrasonic transducer body 3, the top of the ultrasonic transducer body 3 can be sealed, improving the sealing performance during detection. The pressure gauge 15 communicates with one end of the detection pipe 14, which can detect the leaked gas of the ultrasonic transducer body 3.

[0034] The working principle of the present utility model is as follows: The staff inserts the bottom of the ultrasonic transducer body 3 to be detected into the detection groove 2 and makes the detection pipe 14 communicate with the bottom of the ultrasonic transducer body 3. Then, the hydraulic rod 5 is started through an external controller. The hydraulic rod 5 cooperates with the pressure pipe 6 to drive the pressing plate 7 to move downward. When the pressing plate 7 drives the push rod 8 to contact the push block 9, the position of the push block 9 remains unchanged. At this time, the piston piece 10 will be driven to move upward through the vertical rod 18 to compress the gas inside the pressure pipe 6, as Figure 4 shown;

[0035] Continue to control the hydraulic rod 5 to drive the pressure plate 7 to move downward. The pressure plate 7 cooperates with the push rod 8 to push the push block 9 to move. The push block 9 drives the two groups of clamping plates 4 to move relatively to clamp and fix the ultrasonic transducer body 3, improving the stability during detection, as Figure 5 shown;

[0036] While the pressure pipe 6 moves downward, it will drive the sealing plug 12 to insert into the top of the ultrasonic transducer body 3. At this time, start the second solenoid valve 17 to open the air supply pipe 11. The compressed gas inside the pressure pipe 6 will enter the ultrasonic transducer body 3. When there is a lack of airtightness inside the ultrasonic transducer body 3, the gas will enter the detection pipe 14 through the ultrasonic transducer body 3. By observing the numerical change of the pressure gauge 15, the gas leakage situation of the ultrasonic transducer body 3 can be judged. Only one set of driving equipment is required to work during the whole detection process, which can effectively improve the detection efficiency.
