Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] A test fixture for a focused ultrasonic gun transducer includes an upper test fixture shell 1, a lower test fixture shell 2, a carrier 3, an adapter ring 4, and a focused ultrasonic gun transducer 5. The upper test fixture shell 1 has an external thread at one end, and the lower test fixture shell 2 has an internal thread inside. The upper test fixture shell 1 is threadedly connected to the lower test fixture shell 2.
[0028] The outer side of the bearing member 3 is provided with a thread that matches the internal thread of the lower shell 2 of the test fixture, and the bearing member 3 is threadedly connected inside the lower shell 2 of the test fixture;
[0029] The adapter ring 4 has an adapter ring fixing hole 4-1 on its side wall. The focused ultrasonic transducer 5 is disposed inside the adapter ring 4, and the adapter ring 4 is disposed inside the carrier 3.
[0030] An O-ring 6 is fixedly installed in an O-groove at one end of the lower shell 2 of the test fixture to prevent liquid leakage.
[0031] The side wall of the carrier 3 is provided with a set of evenly arranged liquid channels 3-1 and carrier fixing holes 3-2. The flat end of the carrier 3 is provided with symmetrical adjustment process holes 3-4. The middle part of the flat end of the carrier 3 is provided with carrier outlet hole 3-3.
[0032] The liquid channel 3-1 facilitates the entry of liquid between the focused ultrasonic transducer 5 and the probe waterproof membrane 7.
[0033] The focused ultrasonic transducer 5 is fixedly installed inside the adapter ring 4. During the fixed installation, the adapter ring fixing hole 4-1 is connected by a set screw thread and the end of the set screw is pressed against the outer wall of the focused ultrasonic transducer 5.
[0034] The adapter ring 4 is fixedly installed inside the carrier 3. During the fixed installation, the carrier fixing hole 3-2 is connected by a set screw thread and the end of the set screw is pressed against the outside of the adapter ring 4.
[0035] The test fixture upper shell 1 is provided with a wire outlet hole 1-1 at one end. The wire harness of the focused ultrasonic transducer 5 passes through the wire outlet hole 3-3 of the carrier and the wire outlet hole 1-1. The gap between the wire harness of the focused ultrasonic transducer 5 and the wire outlet hole 3-3 of the carrier and the wire outlet hole 1-1 is sealed with sealant. While sealing the liquid, the wire harness is also fixed to prevent external force from damaging the wire harness in the cavity.
[0036] The lower shell 2 of the test fixture is made of transparent material, which facilitates the measurement of focal length.
[0037] The material of the probe waterproof film 7 is polytetrafluoroethylene film.
[0038] Working principle: When not assembled, the liquid is first added to the lower shell 2 of the test fixture. The liquid fills the cavity formed by the focused ultrasonic transducer 5 and the probe waterproof film 7 through the liquid channel 3-1 on the carrier 3. Then the upper shell 1 of the test fixture is screwed on. When in use, the probe waterproof film 7 faces down. At this time, the cavity formed by the focused ultrasonic transducer 5 and the probe waterproof film 7 is filled with liquid.
[0039] The liquid is water, which has excellent sound wave conduction properties, effectively increasing the propagation speed of sound waves while minimizing sound wave attenuation.
[0040] The focal length adjustment method for the focused ultrasonic transducer 5 with different focal lengths is as follows: The fixture is placed vertically, with the upper shell 1 of the test fixture at the bottom, allowing liquid to enter the upper shell 1 of the test fixture to prevent liquid from flowing out during disassembly. The upper shell 1 and the lower shell 2 of the test fixture are separated by threads. The carrier 3 is installed in the inner cavity of the lower shell 2 of the test fixture by threads. The screws are connected by threads in two adjustment process holes 3-4 respectively. By rotating the two screws, the two screws rotate around the axis of the carrier 3, causing the carrier 3 to move axially along the lower shell 2 of the test fixture, thereby adjusting the position of the carrier 3 in the inner cavity of the lower shell 2 of the test fixture, and thus adjusting the focal length of the focused ultrasonic transducer 5.
[0041] The outer diameter of the focused ultrasonic transducer 5 matches the inner diameter of the adapter ring 4. For focused ultrasonic transducers 5 with different diameters, the testing requirements of the focused ultrasonic transducer 5 can be met by replacing the adapter ring 4, thus saving the cost of processing different testing fixtures.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
