Description

Technical Field

[0001] This invention relates to the field of vibration damping and buffering technology, specifically to a multi-stage micro-vibration planar damping vibration control device. Background Technology

[0002] In high-end precision equipment fields such as semiconductor manufacturing, optical inspection, and aerospace, the control of minute vibrations in the core components of the equipment directly affects the operating accuracy and stability of the equipment. Therefore, the industry has put forward strict requirements on the adaptability and ease of installation of vibration damping devices. Among them, the most commonly used vibration damping device is the damping vibration damping device, which is usually composed of components such as a shell, mass system, and damping alloy structure to achieve multi-order minute vibration damping control under different vibration modes in different directions in the plane.

[0003] Currently, most existing micro-vibration damping devices are designed for installation positions with a single shape, which limits their structural adaptability and makes it difficult to meet the vibration damping installation requirements of precision components with different cross-sectional shapes at the same time. In addition, the installation and adjustment process of some devices is cumbersome, and the on-site adaptability is insufficient. When installing and tightening, bolts are usually tightened by screwing. When used in a long-term vibration environment, the bolts are prone to loosening. Therefore, the existing vibration damping devices have a small scope of application and low actual installation stability. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-stage micro-vibration plane damping vibration control device to solve the problems mentioned in the background art, such as cumbersome installation and adjustment process, insufficient on-site adaptability, and the fact that the installation and fastening usually only uses bolt tightening, which makes the bolts easy to loosen when used in a long-term vibration environment.

[0007] Preferably, a sliding pair is rotatably installed on the inner wall of the damping and shock absorption device housing, and a counterweight layer and a hollowed-out damping alloy layer are fixedly installed on the inner wall of the damping and shock absorption device housing, with the counterweight layer slidingly contacting the sliding pair.

[0008] Preferably, the outer wall of the clamping arc-shaped flexible plate is provided with an arc-shaped contact surface, the second fastening bolt slides through the second docking mounting frame, and the clamping arc-shaped flexible plate is made of silicone rubber.

[0009] Preferably, a first guide rod is fixedly connected to the inner wall of the second docking mounting frame, and a second reset spring is sleeved on the first guide rod.

[0010] Preferably, one end of the second reset spring is fixedly connected to the inner wall of the second docking mounting frame, a second fixing plate is slidably mounted on the second docking mounting frame, and the other end of the second reset spring is fixedly connected to the outer wall of the second fixing plate.

[0011] Preferably, a third abutment block is fixedly connected to the outer wall of the second fixing plate, and the outer wall of the third abutment block is provided with a third abutment slope.

[0012] Preferably, a first fixing plate is fixedly connected to the inner wall of the second docking mounting frame, a second guide rod is fixedly connected to the outer wall of the first fixing plate, and a third reset spring is sleeved on the second guide rod.

[0013] Preferably, one end of the third reset spring is fixedly connected to the outer wall of the first fixed plate, and the other end of the third reset spring is fixedly connected to a fourth abutting block, the outer wall of the fourth abutting block being provided with a fourth abutting slope.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In this invention, rotating the first fastening bolt causes one end of the first fastening bolt to gradually enter the interior of the first docking mounting frame. The movement of the first abutting block causes the second abutting inclined surface of its outer wall to abut against the first abutting inclined surface of the outer wall of the second abutting block. The abutting causes the second abutting block to be forced to move the guide rod. This structural design ensures that when the first fastening bolt is loosened by vibration under the high-frequency micro-vibration environment after installation, it will be blocked by the first abutting block, thus ensuring the stability of the device after docking.

[0017] 2. In this invention, when the mounting position has a rectangular outer contour, it is necessary to adjust the second and third fastening bolts to press the curved flexible plate tightly against the outer wall of the mounting position. As the pressing force increases, the curved flexible plate made of silicone rubber deforms. The deformation of the curved flexible plate makes the curved contact surface gradually flatten. At this time, rotating the third fastening bolt pushes the scraper to press the surface of the curved flexible plate while simultaneously smoothing it out. This makes the curved flexible plate more flat and conforms to the surface of the mounting position, further adapting to the fitting and installation of mounting positions with different shapes.

[0018] 3. In this invention, when the mounting position has a rectangular outer contour, rotating the third fastening bolt causes the fourth abutting block and the pushing scraper block to gradually protrude outward, increasing the pressing range of the clamping arc-shaped soft plate and making the clamping arc-shaped soft plate fit the surface of the mounting position more closely.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] This invention provides a technical solution: such as Figure 1 - Figure 8 The multi-stage micro-vibration planar damping vibration control device shown includes a main frame 1 of the vibration control device, a damping vibration control device housing 5 fixedly installed on the outer wall of the main frame 1, and a docking clamping fastening plate 2 fixedly connected to the main frame 1. A first docking mounting frame 3 is fixedly connected to the docking clamping fastening plate 2. A first fastening bolt 4 is threadedly connected to the inner wall of the docking clamping fastening plate 2. A first abutting block 6 is rotatably installed at one end of the first fastening bolt 4. A movable guide rod 7 is slidably installed on the inner wall of the first docking mounting frame 3. A second abutting block 8 is fixedly connected to one end of the movable guide rod 7. The first abutting block 6 and the second abutting block 8 can abut against each other. A second fastening bolt 15 and a third fastening bolt 17 are threadedly connected to the inner wall of the damping vibration control device housing 5. A clamping arc-shaped flexible plate 16 is rotatably installed at one end of the second fastening bolt 15. A second docking mounting frame 18 is rotatably installed at one end of the clamping arc-shaped flexible plate 16.

[0031] The first fastening bolt 4 passes through the mating clamping fastening plate 2. One end of the first fastening bolt 4 is inside the first mating mounting frame 3. The first return spring 9 is sleeved on the moving guide rod 7. The outer wall of the second abutting block 8 has a first abutting slope 10. The outer wall of the first abutting block 6 has a second abutting slope 11. The outer contours of the first abutting slope 10 and the second abutting slope 11 match each other. One end of the first return spring 9 is fixedly connected to the inner wall of the first mating mounting frame 3. The other end of the first return spring 9 is fixedly connected to the outer wall of the second abutting block 8.

[0032] A sliding pair 12 is rotatably installed on the inner wall of the damping and shock absorption device housing 5. A counterweight layer 13 and a hollow damping alloy layer 14 are fixedly installed on the inner wall of the damping and shock absorption device housing 5. The counterweight layer 13 slides against the sliding pair 12.

[0033] The outer wall of the clamping arc-shaped flexible plate 16 is provided with an arc-shaped contact surface 30, the second fastening bolt 15 slides through the second docking mounting frame 18, and the clamping arc-shaped flexible plate 16 is made of silicone rubber.

[0034] The inner wall of the second docking mounting frame 18 is fixedly connected to a first guide rod 23, and a second reset spring 24 is sleeved on the first guide rod 23.

[0035] One end of the second reset spring 24 is fixedly connected to the inner wall of the second docking mounting frame 18. A second fixing plate 29 is slidably mounted on the second docking mounting frame 18, and the other end of the second reset spring 24 is fixedly connected to the outer wall of the second fixing plate 29.

[0036] The outer wall of the second fixing plate 29 is fixedly connected to the third abutment block 19, and the outer wall of the third abutment block 19 is provided with a third abutment slope 20.

[0037] The inner wall of the second docking mounting frame 18 is fixedly connected to a first fixing plate 28, and the outer wall of the first fixing plate 28 is fixedly connected to a second guide rod 26. A third return spring 25 is sleeved on the second guide rod 26. After the third fastening bolt 17 is rotated, it causes the second docking mounting frame 18 at its end to move closer to the outer wall of the clamping arc-shaped flexible plate 16, so that the third abutting block 19 protruding from the outer wall of the second docking mounting frame 18 abuts against the outer wall of the clamping arc-shaped flexible plate 16. The abutting causes the third abutting block 19 to be subjected to an interaction force, and the third abutting block 19 slides towards the inner wall of the second docking mounting frame 18. When the third abutting block 19 slides, it causes the second fixing plate 29 to slide along the first guide rod 23. When sliding, the second return spring 24 is stretched and tightened. The upward movement of the third abutting block 19 causes the third abutting inclined surface 20 opened on its outer wall to abut against the fourth abutting inclined surface 22 on the outer wall of the fourth abutting block 21.

[0038] One end of the third return spring 25 is fixedly connected to the outer wall of the first fixed plate 28, and the other end of the third return spring 25 is fixedly connected to the fourth abutment block 21. The outer wall of the fourth abutment block 21 is provided with a fourth abutment slope 22.

[0039] The outer wall of the fourth contact block 21 is fixedly connected to a push scraper 27, which is used to press and push the arc-shaped soft plate 16.

[0040] Working principle: The structure is mainly composed of the damping and shock absorption device shell 5, counterweight layer 13, hollow damping alloy layer 14, sliding pair 12 and other components. The counterweight layer 13 can control the vibration mode according to each direction. It can make modular designs for each area by using different material volume densities to change the response quality of the damping system. The hollow damping alloy layer 14 changes the stiffness coefficient of the damping alloy by the size and density of the hollowing, thereby controlling the response stiffness under different vibration modes. The sliding pair 12 can reduce the starting friction of the counterweight layer 13 under micro-vibration.

[0041] When using this micro-vibration damping device, firstly, the main frame 1 of the damping control device is fitted onto the vibrating end of the device requiring damping, so that the corresponding mating clamping fastening plates 2 of the two main frames 1 of the damping control device are tightly closed together. Then, the first fastening bolt 4 is rotated. After the first fastening bolt 4 rotates, through the threaded connection with the mating clamping fastening plate 2, one end of the first fastening bolt 4 gradually enters the interior of the first mating mounting frame 3. The movement of the first fastening bolt 4 causes the first abutting block 6 at its end to move synchronously. The movement of the first abutting block 6 causes the second abutting inclined surface 11 on its outer wall to move synchronously. The first contact slope 10 of the second contact block 8 comes into contact with the outer wall of the second contact block 8. The contact causes the second contact block 8 to be forced to move the moving guide rod 7. The moving guide rod 7 slides along the inner wall of the first docking mounting frame 3. At this time, the second contact blocks 8 on the upper and lower sides and the moving guide rod 7 gradually move in opposite directions. The two second contact blocks 8 will jam the first contact block 6, so that the path of the first contact block 6 to reset is blocked. This ensures the stability of the device after docking, so that whenever the first fastening bolt 4 is loosened by vibration in the high-frequency micro-vibration environment after installation, it will be blocked by the first contact block 6.

[0042] Before the device is put into use, it is necessary to adapt it to different shaped installation positions. When the installation position is cylindrical, after the two mating clamping fastening plates 2 are mated and tightly attached, the second fastening bolts 15 on both sides can be rotated to move the second fastening bolts 15 along the inner wall of the damping and shock absorption device housing 5. The movement of the second fastening bolts 15 moves the clamping arc-shaped flexible plate 16 synchronously, so that the clamping arc-shaped flexible plate 16 fits the surface of the installation position. The clamping arc-shaped flexible plate 16 is made of silicone rubber. When the clamping arc-shaped flexible plate 16 is pressed on the surface of the installation position, the arc-shaped contact surface 30 of the outer wall of the clamping arc-shaped flexible plate 16 is deformed after being pressed, and fits more tightly on the surface of the installation position, which can provide good friction, making the installation tighter and more stable.

[0043] When the mounting position has a rectangular outer contour, it is necessary to adjust the second fastening bolt 15 and the third fastening bolt 17. By rotating the second fastening bolt 15, the clamping arc-shaped flexible plate 16 is pressed against the outer contour of the rectangular plane. This pressing causes the clamping arc-shaped flexible plate 16 to fit tightly against the outer wall of the mounting position. As the pressing force increases, the silicone rubber clamping arc-shaped flexible plate 16 deforms. This deformation causes the arc-shaped contact surface 30 to gradually become flat. At this point, the third fastening bolt 17 is rotated... After the fastening bolt 17 rotates, it causes the second mating mounting frame 18 at its end to move closer to the outer wall of the clamping arc-shaped flexible plate 16. This causes the third abutting block 19, which protrudes from the outer wall of the second mating mounting frame 18, to abut against the outer wall of the clamping arc-shaped flexible plate 16. This abutment causes the third abutting block 19 to be subjected to an interaction force, and the third abutting block 19 slides towards the inner wall of the second mating mounting frame 18. When the third abutting block 19 slides, it causes the second fixing plate 29 to slide along the first guide rod 23. During the sliding, the second return spring 24 is stretched and tightened. The upward movement of the three-abutment block 19 causes the third abutment slope 20 on its outer wall to abut against the fourth abutment slope 22 on the outer wall of the fourth abutment block 21. This abutment causes the fourth abutment block 21 to move in the direction of disengaging from the inner wall of the second mating mounting frame 18. The movement of the fourth abutment block 21 slides along the surface of the second guide rod 26. During this sliding motion, the third return spring 25 is stretched and tightened to facilitate subsequent reset. As the fourth abutment block 21 slides outward, it simultaneously slides along with the pushing scraper block 27. As the second mating mounting frame 18 gradually approaches the surface of the clamping curved flexible plate 16, the pushing scraper 27 presses down on the surface of the clamping curved flexible plate 16 while simultaneously pushing and smoothing it. This makes the clamping curved flexible plate 16 more flat and conforms to the surface of the mounting position, further adapting to the fitting and installation of mounting positions of different shapes. Furthermore, the fourth abutment block 21 and the pushing scraper 27 gradually protrude outward, increasing the pressing range of the clamping curved flexible plate 16.
