[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0017] Example 1
[0018] See Figures 1-2 A passive vibration isolation unit includes a vibration isolation ring body 1, a passive vibration isolation component 2, and a compression component 3. The passive vibration isolation component 2 is installed on the vibration isolation ring body 1, and the compression component 3 is installed on the outside of the passive vibration isolation component 2. A handle 4 is symmetrically fixed to the outer wall of the top of the vibration isolation ring body 1. The vibration isolation ring body 1 can be fitted onto a precision part through the handle 4 to facilitate vibration isolation treatment of the equipment. A measuring ruler 5 is symmetrically fixed to the outside of the vibration isolation ring body 1, and one side of the measuring ruler 5 is located on the outer wall of the U-shaped connecting plate 209. The moving U-shaped connecting plate 209 can be measured through the measuring ruler 5 to measure the external dimensions of the bistable buckling beam 206.
[0019] The passive vibration isolation assembly 2 includes a guide port 201, a first helical rod 202, a first rotating handle 203, a fixing plate 204, a guide wheel 205, a bistable buckling beam 206, a mounting groove 207, vibration isolation rubber 208, a U-shaped connecting plate 209, and a first threaded hole 2010. The bistable buckling beam 206 is symmetrically installed inside the vibration isolation ring body 1. The bistable buckling beam 206 has a mounting groove 207, and the vibration isolation rubber 208 is fixedly connected within the mounting groove 207. Guide ports 201 are distributed on the vibration isolation ring body 1 corresponding to the positions of the bistable buckling beam 206. U-shaped connecting plates 209 are fixedly connected to the outer walls on both sides of the bistable buckling beam 206. The first helical rod 202 is rotatably connected to the outer side of the vibration isolation ring body 1. A first threaded hole 2010 is provided on one side of the U-shaped connecting plate 209 corresponding to the position of the first spiral rod 202. A first rotating handle 203 is fixedly connected to the outer wall of one end of the first spiral rod 202. Fixing plates 204 are fixedly distributed on the inner side of the vibration isolation ring body 1. Guide wheels 205 are rotatably connected on the outer wall between the fixing plates 204, and the outer side of the guide wheels 205 is attached to the outer wall of the bistable buckling beam 206. The material of the bistable buckling beam 206 is a shape memory alloy, and grooves are distributed on the outer side of the bistable buckling beam 206. By adjusting the external dimensions, compression ratio, and external dimensions and compression amount of the vibration isolation rubber 208 of the bistable buckling beam 206, quasi-zero stiffness can be achieved within a certain displacement range.
[0020] Working principle: First, the vibration isolation ring body 1 is placed on the precision part using the handle 4. Then, the first rotating handle 203 is rotated to make the first spiral rod 202 rotate. Under the action of the first threaded hole 2010, the guide port 201 on the U-shaped connecting plate 209 is moved. Then, the guide wheel 205 on the fixed plate 204 drives the bistable buckling beam 206 to be adjusted, so that the bistable buckling beam 206 moves linearly along the guide port 201, thereby making the bistable buckling beam 206 fit against the precision part. The vibration isolation rubber 208 on the mounting groove 207 squeezes the precision part. When the precision part is running, the vibration isolation rubber 208 can be used to isolate the vibrating part. Moreover, the bistable buckling beam 206 also has a certain buffering capacity, thereby assisting in the vibration isolation treatment of the precision part. The vibration isolation structure can fit against precision parts of different sizes, thereby adjusting the vibration isolation structure and improving the use effect of the equipment.
[0021] Example 2
[0022] See Figures 1-2 The extrusion assembly 3 includes a second threaded hole 301, a guide hole 302, an arc-shaped extrusion plate 303, a second helical rod 304, a second rotating handle 305, and a guide rod 306. The arc-shaped extrusion plate 303 is installed on the outer side of the bistable buckling beam 206. The second helical rod 304 is rotatably connected to the outer side of the arc-shaped extrusion plate 303. The vibration isolation ring body 1 has a second threaded hole 301 distributed at the position corresponding to the second helical rod 304. The guide rod 306 is symmetrically fixed to the outer side of the arc-shaped extrusion plate 303. The vibration isolation ring body 1 has a guide hole 302 distributed at the position corresponding to the guide rod 306.
[0023] When the vibration-damping rubber 208 on the bistable buckling beam 206 is in contact with the precision structure, the second rotating handle 305 is rotated to make the second spiral rod 304 rotate. Then, under the action of the second threaded hole 301, the guide rod 306 on the arc-shaped extrusion plate 303 moves linearly with the guide hole 302, so that the arc-shaped extrusion plate 303 contacts the bistable buckling beam 206. The arc-shaped extrusion plate 303 extrudes the bistable buckling beam 206, thereby making the vibration-damping rubber 208 on the bistable buckling beam 206 tightly adhere to the precision parts, thus providing vibration isolation for the precision parts. This allows for tight extrusion of the vibration isolation structure, ensuring vibration isolation for the compact structure and improving the equipment's performance.
