Abstract
Description
Technical Field
[0001] This utility model relates to the field of transducer pairing test technology, and in particular to a tooling for transducer pairing test. Background Technology
[0002] In ultrasonic thermal energy meters, the transducer is the core component of ultrasonic measurement. They appear in pairs and are dual-purpose transducers, alternating between each other to convert energy. To improve measurement stability and accuracy, pairing tests must be performed on the two transducers to match their performance indicators. Since this pairing process must be applied in production, it requires ensuring sufficient workload and efficiency. However, traditional laboratory pairing test equipment is not suitable for production, cannot guarantee the pass rate of subsequent processes, and cannot guarantee product quality.
[0003] On the other hand, the existing pairing test equipment has a limited number of transducers that can be tested each time, resulting in low testing efficiency and making it unsuitable for batch testing. At the same time, the current test equipment simulates a single test environment and cannot simulate normal or harsh environments.
[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content
[0005] The purpose of this invention is to provide a transducer pairing test fixture, which solves the technical problem of the current test device having a single simulated test environment, greatly improves work efficiency, and increases the production capacity of enterprises.
[0006] This utility model provides a transducer pairing test fixture, including a test cabinet, a test circuit board, and an ultrasonic wave device. The test circuit board is installed in the test cabinet, and the ultrasonic wave device is connected to the test circuit board. Seven test interfaces are spaced apart at both ends of the test cabinet. The test interfaces at both ends of the test cabinet are aligned. The transducer pairing test fixture also includes a test fixture comprising a base and a middle partition. The base is cuboid in shape and connected to the middle of the test cabinet. A partition slot is provided on the top of the base, and seven through-hole probe mounting holes are spaced apart on the side of the base. The middle partition is also cuboid in shape, with seven large through-holes spaced apart on one long side and seven small through-holes spaced apart on the other long side. When the middle partition is inserted into the partition slot, the axes of the seven small holes or the seven large holes on the middle partition coincide with the axes of the seven probe mounting holes on the base.
[0007] Using the above technical solution, two paired transducers under test are connected to the test interfaces on both sides of the testing cabinet. The ultrasonic probes on the ultrasonic wave device are connected to the probe mounting holes on both sides of the base for receiving or transmitting ultrasonic waves. Since the faster-moving ultrasonic waves in solids are filtered out, this invention only considers the air-borne propagation portion. The small holes in the intermediate partition allow only a small portion of the sound waves to pass through, with the majority being reflected or absorbed. Therefore, more energy is needed to achieve the same effect as a large hole. Through the design of the small and large holes in the intermediate partition, the large hole can simulate a normal environment, while the small hole can simulate harsh environments. This allows for testing in different simulated environments, solving the current technical problem of testing devices simulating only a single testing environment. This invention can provide testing for 7 pairs of transducers, greatly improving work efficiency and increasing enterprise production capacity.
[0008] Furthermore, the transducer pairing test fixture also includes a fixing plate, with two fixing plates vertically connected at intervals on the top of the test cabinet; the base is located between the two fixing plates, and the two fixing plates abut against the two short sides of the base respectively.
[0009] Furthermore, the transducer pairing test fixture also includes side plates and clips. The clips are connected to both sides of the fixing plate, and the side plates abut against the long side of the base, with the clips pressing against the side plates. The side plates have seven wire holes corresponding to the probe mounting holes. The fixing plate and side plates secure the base to the testing cabinet, preventing the base from shaking during testing and affecting the test results. When the ultrasonic probe is connected to the probe mounting holes on both sides of the base, the wires pass through these holes.
[0010] Furthermore, the distance between adjacent probe mounting holes is equal.
[0011] Furthermore, two handle openings are provided at both the upper and lower edges of the middle partition; the handle openings are designed to facilitate the removal of the middle partition from the partition slot.
[0012] This utility model relates to a transducer pairing test fixture. In use, two paired transducers are connected to the test interfaces on either side of the testing cabinet. The ultrasonic probes from the ultrasonic wave device are connected to the corresponding probe mounting holes on either side of the base for receiving or transmitting ultrasonic waves. Since the faster-moving ultrasonic waves in solids are filtered out, this utility model only considers the portion that propagates through air. The small holes in the intermediate partition allow only a small portion of the sound waves to pass through, with the majority being reflected or absorbed. Therefore, more energy is needed to achieve the same effect as a large hole. Through the design of the small and large holes in the intermediate partition, the large hole can simulate a normal environment, while the small hole can simulate a harsh environment. This allows for testing in different simulated environments, solving the technical problem of current testing devices simulating only a single testing environment. This utility model can provide testing for 7 pairs of transducers, greatly improving work efficiency and increasing enterprise production capacity. Attached Figure Description

Figure 2 for Figure 1 A side view schematic diagram of the fixture used for transducer pairing test. Figure 3 for Figure 1 A schematic diagram of the structure of the transducer pairing test fixture. Figure 4 for Figure 1 A schematic diagram of the structure of the intermediate partition plate used in the transducer pairing test fixture. Figure 5 for Figure 1 This is a schematic diagram showing the disassembled structure of the transducer pairing test fixture. Please refer to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The transducer pairing test fixture provided in this embodiment includes a test cabinet 100, a test circuit board, and an ultrasonic wave device. The test circuit board is installed in the test cabinet 100, and the ultrasonic wave device is connected to the test circuit board. Seven test interfaces 110 are installed at intervals on both sides of the top of the test cabinet 100. The test interfaces 110 on both sides of the top of the test cabinet 100 are aligned. The transducer pairing test fixture also includes a test fixture 200, which includes a base 210 and a middle partition 240. The base 210 is rectangular and is connected to the top of the test cabinet 100. The middle part; a partition socket 220 is provided on the top of the base 210, and seven through probe mounting holes 230 are provided at intervals on the side of the base 210; the middle partition 240 is cuboid in shape, and seven through large holes 250 are provided at intervals on one long side of the middle partition 240, and seven through small holes 260 are provided at intervals on the other long side of the middle partition 240; when the middle partition 240 is inserted into the partition socket 220, the axis of the seven small holes 260 or the axis of the seven large holes 250 on the middle partition 240 coincides with the axis of the seven probe mounting holes 230 on the base 210.
[0028] When using the transducer pairing test fixture of this utility model, two paired transducers under test are connected to the test interfaces 110 on both sides of the test cabinet 100, and the ultrasonic probes on the ultrasonic wave device are connected to the probe mounting holes 230 on both sides of the base 210 to receive or transmit ultrasonic waves.
[0029] It should be noted that the faster ultrasonic waves propagating in solids have already been filtered out, so this invention only considers the part that relies on air propagation; the small hole 260 on the intermediate partition 240 allows only a small portion of the sound waves to pass through, while most of the rest are reflected or absorbed; thus, more energy is needed to achieve the same effect as the large hole 250.
[0030] This invention, through the design of small holes 260 and large holes 250 on the intermediate partition 240, allows the use of large holes 250 to simulate normal environments and small holes 260 to simulate harsh environments; it enables testing in different simulated environments and solves the technical problem of current testing devices simulating only one testing environment; this invention can provide testing for 7 pairs of transducers, greatly improving work efficiency and increasing enterprise production capacity;
[0031] Experiments show that for the same pair of probes, under the same environment, the required excitation voltage is also the same to achieve the same effect. For different probes, the environment for a large aperture of 250° is basically the same, and the environment for a small aperture of 260° is also basically the same, satisfying the same simulation environment. In addition, to meet our normal measurement needs, we can check the required excitation voltage. If the desired effect is met, we can control the consistency of the probes by checking the excitation voltage.
[0032] Further reference Figure 1 The transducer pairing test fixture 200 of this utility model also includes a fixing plate 300, two of which are vertically connected at intervals on the top of the test cabinet 100; the base 210 is located between the two fixing plates 300, and the two fixing plates 300 abut against the two short sides of the base 210 respectively; the transducer pairing test fixture 200 also includes a side plate 400 and a buckle 500, the buckle 500 is connected to both sides of the fixing plate 300, and the side plate 400 abuts against the long side of the base 210 respectively, the buckle 500 pressing on the side plate 400; the side plate 400 is provided with 7 wire holes 410 corresponding to the probe mounting holes 230.
[0033] It should be noted that the base 210 can be fixed to the testing cabinet 100 by the fixing plate 300 and the side plate 400 to prevent the base 210 from shaking during the test, thus affecting the test results; when the ultrasonic probe is connected to the probe mounting holes 230 on both sides of the base 210, the wire passes through the wire hole 410.
[0034] Furthermore, the distance between adjacent probe mounting holes 230 is equal; two handle openings 270 are provided at the upper and lower edges of the intermediate partition plate 240.
[0035] It should be noted that the design of the handle opening 270 facilitates the removal of the middle partition 240 from the partition insertion opening 220.
[0036] As can be seen from the above description, the advantages of this utility model are:
[0037] 1. The transducer pairing test fixture of this utility model is used to connect two paired transducers to the test interfaces 110 on both sides of the test cabinet 100, and connect the ultrasonic probes on the ultrasonic wave device to the probe mounting holes 230 on both sides of the base 210 to receive or transmit ultrasonic waves.
[0038] 2. In the transducer pairing test fixture of this utility model, the ultrasonic waves that travel faster in solids have been filtered out, so this utility model only considers the part that relies on air propagation; the small hole 260 on the intermediate partition 240 allows only a small portion of the sound waves to pass through, while most of the rest will be reflected or absorbed; thus, more energy is needed to achieve the same effect as the large hole 250.
[0039] 3. The transducer pairing test fixture of this utility model, through the design of small holes 260 and large holes 250 on the intermediate partition plate 240, can use large holes 250 to simulate normal environment and small holes 260 to simulate harsh environment test; realize the test of different simulated environment, and solve the technical problem of the current test device simulating only one test environment; this utility model can provide 7 pairs of transducers for testing, which greatly improves work efficiency and increases the production capacity of enterprises.
