[0015] 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.

[0016] Please see Figures 1-5 This utility model provides a technical solution: a mechanical clamping and adjusting assembly for optimizing the vibration mode of a high-speed rotating viscoelastic plate, including a base plate 1, a support frame 2 and a support column 5. The support frame 2 is provided on the upper end of the base plate 1, and the support frame 2 is connected to a simulated rotation mechanism 3. An adjusting mechanism 4 is provided at equal angles on the side of the base plate 1, and the support column 5 is provided at equal angles on the upper end of the adjusting mechanism 4. A limit mechanism 6 is connected to the side of the support column 5.

[0017] The simulated rotation mechanism 3 includes a drive motor 31, a housing 32, a threaded column 33, a circular block 34, a support plate 35, and a limit bolt 36. The lower end of the support frame 2 is connected to the drive motor 31, the output shaft of the drive motor 31 is connected to the housing 32, the housing 32 is threadedly connected to the threaded column 33, the upper end of the threaded column 33 is connected to the circular block 34, the support plate 35 is provided on the side of the circular block 34, and the limit bolt 36 is threadedly connected to the side of the housing 32. The output shaft of the drive motor 31 is rotatably connected to the support frame 2, and the housing 32 is positioned above the support frame 2. The limiting bolt 36 is attached to the side of the threaded post 33. Rotating the limiting bolt 36 on the side of the housing 32, and then rotating the threaded post 33, causes the circular block 34 and the support plate 35 to move up and down, thereby adjusting the height of the circular block 34 and the support plate 35. This makes the device suitable for different viscoelastic plates. During the simulation, the viscoelastic plate is placed on the support plate 35 for installation. Then, during the test, the drive motor 31 is started to drive the housing 32 to rotate, and at the same time, the viscoelastic plate rotates, thereby simulating high-speed rotation.

[0018] The adjusting mechanism 4 includes a first connecting post 41, a first sliding rod 42, a locking block 43, an arc-shaped rod 44, a second connecting post 45, a second sliding rod 46, and an arc-shaped shell 47. The first connecting post 41 is equidistantly arranged on the side of the base plate 1. The first sliding rod 42 is slidably connected to the side of the first connecting post 41. The locking block 43 is connected to the first sliding rod 42. A support post 5 is provided at the upper end of the locking block 43. Arc-shaped rods 44 are symmetrically arranged on the side of the locking block 43. The second connecting post 45 is equidistantly embedded on the side of the base plate 1. A second sliding rod 46 is slidably connected to the second sliding rod 46, which is connected to an arc-shaped shell 47. The arc-shaped rod 44 is slidably connected to the arc-shaped shell 47. During use, the locking block 43 is pulled according to the size of the viscoelastic plate, thereby driving the first sliding rod 42 to slide along the first connecting post 41 on the side of the base plate 1. At the same time, the arc-shaped rod 44 on the side of the locking block 43 slides synchronously along the arc-shaped shell 47. The arc-shaped shell 47 is slidably connected to the second connecting post 45 embedded on the side of the base plate 1 through the second sliding rod 46, ensuring that the movement trajectory of the locking block 43 is stable.

[0019] The limiting mechanism 6 includes a locking plate 61, a sliding groove 62, a circular column 63, a square rod 64, a positioning bolt 65, a circular shell 66, a slider 67, a ball 68, and a support spring 69. The support column 63 has a locking plate 61 symmetrically arranged on its side, and a sliding groove 62 is formed on its side. A circular column 63 is arranged inside the sliding groove 62. Two square rods 64 are symmetrically slidably arranged on the side of the circular column 63. Positioning bolts 65 are threadedly connected to the sides of the square rods 64. A circular shell 66 is connected to the adjacent surfaces of the two locking plates 61. A slider 67 is slidably connected to the circular shell 66, and a ball 68 is rotatably connected to the slider 67. The support spring 69 is installed inside the support column 6. The square rod 64 is slidably disposed inside the slide groove 62. The square rod 64 is connected to the clamping plate 61. One end of the support spring 69 is connected to the inner wall of the circular shell 66, and the other end of the support spring 69 is connected to the side wall of the slider 67. Loosen the positioning bolt 65 on the side of the square rod 64 to push the square rod 64 to slide along the circular column 63 in the slide groove 62 on the side of the support column 5. Since the square rod 64 is connected to the clamping plate 61, it can drive the symmetrical clamping plates 61 to move synchronously until the distance between the two clamping plates 61 matches the edge size of the viscoelastic plate to be tested. Then tighten the positioning bolt 65 to fix the position of the square rod 64.

[0020] Working principle: According to Figures 1 to 2 Rotate the limiting bolt 36 on the side of the housing 32, and then rotate the threaded column 33. The rotation of the threaded column 33 drives the circular block 34 and the support plate 35 to move up and down, thereby adjusting the height of the circular block 34 and the support plate 35. This makes it easy for the device to be used with different viscoelastic plates. During the simulation, the viscoelastic plate is placed on the support plate 35 for installation. Then, during the test, the drive motor 31 is started to drive the housing 32 to rotate, and at the same time, the viscoelastic plate is driven to rotate, thereby simulating high-speed rotation. according to Figure 3 During use, the clamping block 43 is pulled according to the size of the viscoelastic plate, thereby driving the first sliding rod 42 to slide along the first connecting post 41 on the side of the base plate 1. At the same time, the arc-shaped rod 44 on the side of the clamping block 43 slides synchronously along the arc-shaped shell 47. The arc-shaped shell 47 is slidably connected to the second connecting post 45 embedded on the side of the base plate 1 through the second sliding rod 46, ensuring that the movement trajectory of the clamping block 43 is stable. Through the linkage of multiple sets of clamping blocks 43, arc-shaped rods 44 and arc-shaped shells 47 set at equal angles, the support post 5 at the upper end of the clamping block 43 is evenly distributed at different positions on the edge of the viscoelastic plate, adapting to the clamping requirements of viscoelastic plates of different sizes, while avoiding uneven force on the viscoelastic plate during the simulation. according to Figures 4 to 5Before installing the viscoelastic plate, loosen the positioning bolt 65 on the side of the square rod 64 and push the square rod 64 to slide along the circular column 63 in the sliding groove 62 on the side of the support column 5. Since the square rod 64 is connected to the clamping plate 61, it can drive the symmetrical clamping plates 61 to move synchronously until the distance between the two clamping plates 61 matches the edge size of the viscoelastic plate to be tested. Then tighten the positioning bolt 65 to fix the position of the square rod 64. When the edge of the viscoelastic plate is in contact with the clamping plate 61, the ball 68 is squeezed by the plate and pushes the slider 67 to slide along the circular shell 66 and compress the support spring 69. The reaction force of the support spring 69 makes the ball 68 tightly abut against the surface of the plate, thereby avoiding excessive clamping and deformation of the plate. At the same time, the rolling contact between the ball 68 and the viscoelastic plate reduces friction interference, thereby improving the accuracy of the data of the simulated rotation of the viscoelastic plate. In this device, the drive motor 31 is started after being connected to an external power source via a power cord. The drive motor 31 is a known and existing technology on the market and will not be described in detail here.

[0021] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
