Description

Technical Field

[0001] This utility model relates to the technical field of testing devices for noise reduction materials, specifically a testing device for noise reduction materials. Background Technology

[0002] In the research, development, production, and quality testing of noise reduction materials, various performance tests need to be conducted. To ensure the accuracy and reliability of the test results, the noise reduction materials must be stably and firmly fixed on the testing device.

[0003] Currently, most existing noise reduction material testing devices employ separate clamping and pressing mechanisms to hold the material on both sides and press the material surface, respectively. However, this design has significant drawbacks. It requires operating different control components to move the clamping mechanism and activate the pressing mechanism separately, resulting in a cumbersome and inefficient process. Furthermore, it's difficult to ensure the synchronization and coordination of the clamping and pressing actions, potentially affecting the accuracy of the test results and failing to meet the demands of modern large-scale production and efficient testing.

[0004] To address the aforementioned issues, we propose a testing device for noise reduction materials. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: a testing device for noise reduction materials, including a testing body 1, a first clamping block 2, a second clamping block 3, and a linkage control device 4. The first clamping block 2 and the second clamping block 3 are slidably connected inside the testing body 1, and the first clamping block 2 and the second clamping block 3 are arranged opposite to each other so as to clamp and fix the noise reduction material from both sides.

[0029] It should be noted here that, such as Figure 1 As shown, the noise reduction material is placed between the first clamping block 2 and the second clamping block 3 from the direction close to the driving device 41, and the detection body 1 is provided with a large space in the direction close to the driving device 41 so that there is enough space to place the noise reduction material.

[0030] The linkage control device 4 includes a drive device 41, a first linkage device 42, and a second linkage device 43. The drive device 41 is installed through the side wall of the detection machine body 1. One end of the drive device 41 is provided with a gear 413 for driving the first linkage device 42 and the second linkage device 43. The first linkage device 42 and the second linkage device 43 can be driven simultaneously by the drive device 41, thereby realizing the sliding control of the first clamping block 2 and the second clamping block 3.

[0031] The driving device 41 includes a handwheel 411, a rotating shaft 412, a stop block 416, a second elastic element 417, and a limiting rod 414. The rotating shaft 412 passes through the side wall of the detection machine body 1. One end of the rotating shaft 412 extends into the inner cavity of the detection machine body 1 and is fixedly connected to the gear 413. The other end of the rotating shaft 412 is located outside the detection machine body 1 and is connected to the handwheel 411. By rotating the handwheel 411, the rotating shaft 412 and the gear 413 can be driven to rotate. The rotating shaft 412 is not only rotatably connected to the side wall of the detection machine body 1, but it can also slide on the side wall of the detection machine body 1.

[0032] The second elastic element 417 is sleeved on the outer wall of the rotating shaft 412. One end of the second elastic element 417 is fixedly connected to the outer wall of the detection body 1, and the other end of the second elastic element 417 is fixedly connected to the connection between the handwheel 411 and the rotating shaft 412, which can play a buffering and resetting role. The side wall of the rotating shaft 412 is fixedly connected to the stop 416 for limiting the position of the gear 413, ensuring the stable operation of the gear 413. The limiting rod 414 is inserted into the handwheel 411, and an elastic element 415 is sleeved on the outer wall of the limiting rod 414. One end of the elastic element 415 is connected to the handwheel 411, and the other end of the elastic element 415 is connected to the side wall of the limiting rod 414. The outer wall of the testing machine body 1 is provided with a rubber ring near the connection of the rotating shaft 412 for the limiting rod 414 to abut against it. When the limiting rod 414 is inserted into the rubber ring, the handwheel 411 can be limited and fixed to prevent the handwheel 411 from rotating due to accidental contact during the test, which would affect the test results.

[0033] The first linkage device 42 includes a first internal gear 421, a first rotating rod 422, and a second rotating rod 423. The first internal gear 421 meshes with the gear 413, and when the gear 413 rotates, it drives the first internal gear 421 to rotate. One end of the first rotating rod 422 and one end of the second rotating rod 423 are rotatably connected to the side wall of the first internal gear 421, and the other end of the first rotating rod 422 is rotatably connected to the side wall of the first clamping block 2. The other end of the second rotating rod 423 is rotatably connected to the side wall of the second clamping block 3. When the first internal gear 421 rotates, through the transmission action of the first rotating rod 422 and the second rotating rod 423, the first clamping block 2 and the second clamping block 3 can be driven to slide within the detection body 1, realizing the clamping or releasing operation of the noise reduction material. The bottom surface of the inner cavity of the detection body 1 is provided with a bracket for supporting the first internal gear 421 to ensure the stable operation of the first internal gear 421. The size of the bracket in the detection body 1 is not limited, but it needs to be able to support the stable rotation of the first internal gear 421 and minimize friction as much as possible.

[0034] The cooperation between the second elastic element 417 and the stop block 416 causes the restoring force of the second elastic element 417 to pull the gear 413 into the first internal gear 421, and to push one end of the limiting rod 414 into the rubber ring on the outer side wall of the detection machine body 1, thereby limiting the position of the gear 413. At the same time, the large frictional force generated by the limiting rod 414 and the rubber ring limits the first internal gear 421, so that the first clamping block 2 and the second clamping block 3 do not displace.

[0035] The second linkage device 43 includes a second internal gear 431, a third rotating rod 432, and a sleeve rod 433. The second internal gear 431 meshes with the gear 413, and when the gear 413 rotates, it drives the second internal gear 431 to rotate. One end of the third rotating rod 432 is rotatably connected to the side wall of the second internal gear 431, and the other end is rotatably connected to one end of the sleeve rod 433. The other end of the sleeve rod 433 is connected to the pressing device 32. When the second internal gear 431 rotates, the pressing device 32 can be opened and closed through the transmission action of the third rotating rod 432 and the sleeve rod 433, realizing the pressing or loosening operation of the noise reduction material. A collar is provided at the connection of the sleeve rod 433 to the pressing device 32, and the collar is sleeved on the handle of the pressing device 32. The bottom surface of the inner cavity of the detection body 1 is provided with a bracket for supporting the second internal gear 431 to ensure the stable operation of the second internal gear 431. It should be noted that, in order to enhance the connection strength between the sleeve rod 433 and the third rotating rod 432, reinforcing ribs may also be appropriately installed.

[0036] The thickness of the first internal gear 421 and the second internal gear 431 is not limited, but it is necessary to ensure that the gear 413 is not easily dislodged during meshing. The size of the bracket in the detection body 1 is not limited, but it is necessary to be able to support the stable rotation of the second internal gear 431 and minimize friction as much as possible.

[0037] The first clamping block 2 includes a first slider 21, a clamping frame 22, and a rubber plate 23. The first slider 21 is slidably connected to the bottom surface of the inner cavity of the detection body 1 to ensure stable sliding of the first clamping block. The clamping frame 22 is fixedly connected to the top surface of the first slider 21 for direct contact and clamping of the noise reduction material. The clamping frame 22 is provided with the rubber plate 23, which has good elasticity and friction to prevent damage to the noise reduction material during clamping and improve clamping stability. The clamping frame 22 adopts an inverted L-shaped structure, with the rubber plate 23 at the opening. When the noise reduction material is inserted, it pushes open the rubber plate 23, and the restoring force of the rubber plate 23 presses the noise reduction material to achieve positioning. Because the rubber plate 23 is a soft material, the noise reduction material can relatively easily push open the rubber plate 23, preventing the clamping effect from being impossible due to the material being too hard.

[0038] The second clamping block 3 includes a second slider 31 and a clamping device 32. The second slider 31 is slidably connected to the bottom surface of the inner cavity of the detection body 1 to ensure stable sliding. The top surface of the second slider 31 is provided with a clamping device 32, which can clamp the noise reduction material under the drive of the second linkage device 43. The clamping device 32 is a TCAAA-12270 vertical quick clamp, which has its own damping effect and can achieve positioning during clamping.

[0039] The bottom surface of the inner cavity of the testing machine body 1 is provided with a sliding groove 11. The first clamping block 2 and the second clamping block 3 are slidably connected in the sliding groove 11. The sliding groove can guide the sliding of the first clamping block and the second clamping block, ensuring accurate sliding direction and improving the precision of clamping and pressing operations. The side walls of the first clamping block 2 and the second clamping block 3 are connected to the inner side wall of the sliding groove 11 through slide rails to reduce friction.

[0040] Working principle:

[0041] When not being tested, the testing device of this application is in the initial state, the first clamping block 2 and the second clamping block 3 are in the released position, the clamping device 32 is in the raised state, and the limiting rod 414 is inserted into the rubber ring on the outer side wall of the testing machine body 1 to limit and fix the handwheel 411.

[0042] Material placement: The noise reduction material to be tested is placed between the first clamping block 2 and the second clamping block 3. The noise reduction material pushes the rubber plate 23 open, and the restoring force of the rubber plate 23 presses the noise reduction material to ensure that the material is placed stably.

[0043] Release the limit: Pull the limit rod 414 outward to pull it out of the rubber ring, thereby releasing the limit on the handwheel 411.

[0044] Clamping and pressing operation: Since the gear 413 is initially engaged with the first internal gear 421, rotating the handwheel 411 (rotation direction is not limited, clockwise or counterclockwise rotation can achieve relative sliding of the first clamping block 2 and the second clamping block 3) will drive the gear 413 through the rotating shaft 412. The gear 413 will drive the first internal gear 421 to rotate. Through the transmission action of the first rotating rod 422 and the second rotating rod 423, the first clamping block 2 and the second clamping block 3 will slide relative to each other in the sliding groove 11, gradually approaching the noise reduction material, thereby achieving clamping of the noise reduction material.

[0045] Upon initial clamping, push the handwheel 411 to drive the 412 to slide into the detection body 1. When the gear 413 meshes with the second internal gear 431, as... Figure 1 With the center position as a reference, rotating the handwheel 411 counterclockwise causes the rotating shaft 412 and the gear 413 to rotate synchronously. The gear 413 drives the second internal gear 431 to rotate, and the counterclockwise rotation of the second internal gear 431 drives the third rotating rod 432. The third rotating rod 432 drives the sleeve rod 433 to pull the handle of the clamping device 32 downward, thereby enabling the clamping device 32 to clamp the noise-reducing material. When the clamping and pressing force reaches the required level, the rotation of the handwheel 411 is stopped.

[0046] Testing: After the noise reduction material is clamped and pressed, the testing equipment can be started to test the various properties of the noise reduction material.

[0047] Release Material: After the test is completed, first pull the limiting rod 414 outward to remove it from the rubber ring, releasing the limitation on the handwheel 411. Push the handwheel 411 and drive the 412 to slide into the testing body 1. When the gear 413 meshes with the second internal gear 431, rotate the handwheel 411 clockwise. The handwheel 411 drives the rotating shaft 412 and the gear 413 to rotate synchronously. The gear 413 drives the second internal gear 431 to rotate. The second internal gear 431 rotates clockwise, driving the third rotating rod 432. The third rotating rod 432 drives the sleeve rod 433 to push the handle of the clamping device 32 upward, causing the clamping device 32 to lift upward and release the noise reduction material.

[0048] After the initial lifting is completed, release the control of the handwheel 411, so that the restoring force of the second elastic element 417 drives the rotating shaft 412 to slide, so that the gear 413 returns to the first internal gear 421 to complete the meshing, and rotate the handwheel 411 in the opposite direction to the rotation direction of the first internal gear 421 during the initial clamping and pressing operation, thereby pushing the first clamping block 2 and the second clamping block 3 away from each other, releasing the noise reduction material, and then taking the noise reduction material out of the rubber plate 23, and restoring the device to the initial state for the next test.
