Description

[0002] In the production, research and development, and quality inspection of audio equipment, it is often necessary to conduct precise audio tests on the products. Many audio devices, such as headphones, speakers, mobile phones, etc., are usually provided with various small holes for ventilation, tuning and other functions on their shells. When conducting audio tests, the presence of these small holes may interfere with the test results, resulting in inaccurate test data and failure to truly reflect the audio performance of the product. Sound may leak out from the small holes, affecting the measurement accuracy of parameters such as sound pressure level and frequency response. External noise is also easily transmitted through these small holes and mixed into the test signal, further increasing the test error. Therefore, in the process of audio testing the body, it is necessary to block the small holes for ventilation, tuning and other functions;

[0003] At present, the traditional way of plugging holes is mostly to manually use simple tools such as tape and rubber plugs to seal them. However, due to the subjectivity and instability of manual operation, the tightness and sealing of the plugging by different workers vary greatly, making it difficult to ensure the consistency of the plugging effect each time, which in turn causes serious interference to the accuracy of the audio test results.

[0047] The inside of the workbench 1 is provided with a plurality of square grooves 54 which are equidistantly connected to the inside of the L-shaped slot 51, and each square groove 54 is provided with a square block 56 and a spring 55, the two ends of the spring 55 are respectively fixedly connected to the square block 56 and the workbench 1, the square block 56 and the workbench 1 are slidably connected, and the upper surface of each square block 56 is fixedly connected to a hemispherical block 57, and the hemispherical block 57 is inserted in an arc-shaped embedded groove 58 provided on the bottom surface of the L-shaped plug block 52.

[0048] A bearing 510 is installed at the top of the square plate 53, and a threaded rod 59 is inserted into the interior of the bearing 510. The threaded rod 59 is rotatably connected to the square plate 53 through the bearing 510. The threaded rod 59 longitudinally penetrates the limit housing 313, and the threaded rod 59 and the limit housing 313 are threadedly connected.

[0049] Working principle: the electric hydraulic push rod 32 should be in the initial unactivated state, its telescopic rod is retracted to the shortest, the rectangular pressing plate 33 is in the starting position, the audio device body to be tested is placed on the placement plate 314, the part of the body that needs to be plugged is facing the side of the rectangular frame 312, the electric hydraulic push rod 32 is started, and after the electric hydraulic push rod 32 receives the start signal, its telescopic rod begins to slowly extend, and as the telescopic rod extends, the first built-in slide 34 is pushed to slide downward in the first rectangular slide groove 38 of the U-shaped bracket 31, and the second built-in slide The connecting plate 36 on one side of the plate 35 initially fits the first built-in slide plate 34, and under the gravity of the second built-in slide plate 35 itself and the weight plate 323 and other components, the connecting plate 36 moves downward with the first built-in slide plate 34, driving the second built-in slide plate 35 to move downward. During the downward movement of the second built-in slide plate 35, the side slide plates 324 fixed on both sides thereof slide stably in the second rectangular slide grooves 318 of the U-shaped bracket 31, ensuring the accurate movement direction, and at the same time driving the two first tooth plates 37 fixed on one side of the second built-in slide plate 35 to move downward;

[0050] When the two first tooth plates 37 move downward, they are inserted into the longitudinal slots 316 of the workbench 1 and slidably connected thereto, thereby ensuring a stable movement trajectory. The first tooth plates 37 mesh with the long gear 39 rotatably connected to the rotating shaft 310, thereby driving the long gear 39 to rotate on the surface of the rotating shaft 310. When the long gear 39 rotates, it meshes with the second tooth plate 311 on the rectangular pressing plate 33, thereby driving the second tooth plate 311 and the rectangular pressing plate 33 to move synchronously toward the direction of the machine body on the placement plate 314. The two U-shaped clamping plates 319 on the bottom surface of the rectangular pressing plate 33 slide in the horizontal slide groove 315 of the workbench 1, and the rollers 320 inside the U-shaped clamping plates 319 roll against the wall of the slide groove, making the rectangular pressing plate 33 move more smoothly and smoothly, reducing the friction resistance during the movement of the rectangular pressing plate 33, and finally achieving the clamping action of the machine body.

[0051] While the rectangular pressing plate 33 is clamping the machine body, the rectangular frame 312 on the workbench 1 is made of foam material and has certain sound absorption and blocking properties. As the rectangular pressing plate 33 approaches, the rectangular frame 312 is closely attached to the position where the hole needs to be blocked on the surface of the machine body, and the hole on the machine body is blocked to prevent sound leakage and external noise from entering, creating good conditions for audio testing;

[0052] When the first built-in slide plate 34 continues to move downward, after the hole in the machine body is blocked, due to the gravity of the second built-in slide plate 35, the upper connecting plate 321 and the counterweight plate 323 and other components, the connecting plate 36 no longer moves with the first built-in slide plate 34. At this time, the second built-in slide plate 35 and its associated components are relied on to maintain a stable clamping of the machine body. If the clamping force needs to be adjusted for different machine models, it can be achieved by increasing or decreasing the number of counterweight plates 323 sleeved on the optical axis 322, ensuring that a suitable and stable clamping force can be provided for various machine models to avoid damage to the machine body due to over-tight clamping.

[0053] According to the model and structural characteristics of the machine body to be tested, the best position for squeezing the rubber plate 43 during the clamping process is determined. Through manual operation, the T-shaped block 42 on the rubber plate 43 is slid in the T-shaped slide groove 41 of the rectangular pressing plate 33, and the T-shaped block 42 is inserted into the T-shaped slide groove 41 at the corresponding position, thereby adjusting the clamping position of the rubber plate 43 on the machine body to meet the needs of different machine models. At the same time, the embedded groove 44 on the rubber plate 43 can reduce the contact area with the machine body to avoid affecting the audio test effect due to large-area contact;

[0054] Due to the different hole positions of different machine bodies, when it is found that the blocking hole position has deviation after the machine body is initially placed, it is necessary to adjust the position of the rectangular frame 312. The operator applies force to the square plate 53 so that the square plate 53 drives the L-shaped plug 52 to slide in the L-shaped slot 51 of the workbench 1. During this process, the arc-shaped embedded groove 58 on the bottom surface of the L-shaped plug 52 squeezes the hemispherical block 57, so that the hemispherical block 57 overcomes the elastic force of the spring 55 and slides out of the arc-shaped embedded groove 58 and slides into the square groove 54 until the hemispherical block 57 slides out from the bottom surface of the L-shaped plug 52, and the square plate 53 is continuously moved. When the hemispherical block 57 is moved to the appropriate position, the hemispherical block 57 at the corresponding position can be inserted into the arc-shaped embedded groove 58 under the elastic force of the spring 55, so as to fix the position of the square plate 53, thereby completing the adjustment of the horizontal position of the rectangular frame 312. By rotating the threaded rod 59, the limiting shell 313 can slide on the surface of the square plate 53, thereby adjusting the longitudinal position of the rectangular frame 312 and correcting the blocking position of the body. If there is still a slight deviation in the blocking position, the body on the plate 314 can be moved, and the rubber plate 43 can be moved synchronously with the body to ensure that the blocking position is accurate.
