Description

Technical Field

[0001] This utility model relates to the field of vibration isolator technology, specifically to a vibration isolator with easily replaceable rubber pads. Background Technology

[0002] In the field of vibration isolation, the performance and reliability of vibration isolators are of great significance for protecting equipment and ensuring the normal operation of work. However, existing vibration isolators have many problems in practical applications.

[0003] Replacing the rubber vibration isolation components of traditional vibration isolators has always been a thorny problem. Due to design limitations, the rubber components of these isolators are usually tightly integrated with the main structure, and the connection method is complex. This makes replacement extremely difficult when the rubber components are damaged. It not only requires professional technicians but also relies on specific tools. The entire process is cumbersome and time-consuming. This not only increases the cost and difficulty of maintenance but also significantly prolongs the downtime of the equipment after the rubber components are damaged, seriously affecting the continuity and efficiency of production.

[0004] A cantilever damping vibration isolator, as described in announcement number CN103322104B, includes a supporting plate comprising a supporting surface, with a cantilever bent at one end and a load-bearing surface bent at the other end of the cantilever. It also includes a base positioned below the supporting surface. At least one set of compression springs, bolted to the cantilever, is located between the base and the supporting surface at one end, and at least one set of tension springs is located at the other end. A top rod with a pre-damped groove is provided between the base and the supporting surface, on the outside of the tension springs. A base rubber pad is provided on the lower end face of the base. A load-bearing rubber pad is provided on the upper end face of the load-bearing surface. This invention effectively improves vibration isolation and enhances equipment stability.

[0005] In the use of the aforementioned cantilever damping vibration isolator, the rubber pads on the base become damaged after prolonged use, making replacement inconvenient. However, other problems also exist. For example, the vibration isolator often falls short when dealing with strong external vibrations. In environments with strong vibrations such as the operation of large machinery or earthquakes, the damping effect of traditional vibration isolators cannot meet the actual needs. They may not be able to effectively absorb and disperse vibration energy, causing the protected equipment to still suffer significant impacts, which in turn affects the equipment's accuracy, performance, and even shortens its service life. Utility Model Content

[0006] The purpose of this invention is to provide a vibration isolator with easily replaceable rubber pads, in order to solve the problems mentioned in the background art, such as the rubber pads becoming damaged after long-term use, making them inconvenient to replace, and the inability to effectively absorb and disperse vibration energy, resulting in the protected equipment still being subjected to significant impact.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a vibration isolator that facilitates the replacement of rubber pads, comprising a support frame and a fixing plate disposed above the support frame;

[0008] The upper end of the fixed plate is equipped with a vibration damping pad, and a device hole is opened on the left side of the upper end of the fixed plate. A compression spring is fixedly installed inside the lower end of the device hole opened on the left side of the upper end of the fixed plate. A quick-release mechanism is provided inside the fixed plate, and two quick-release mechanisms are symmetrically distributed with support frames. A guide wheel is fixedly installed in the middle of the device hole opened on the left side of the upper end of the fixed plate, and four guide wheels are evenly distributed inside the fixed plate. The guide wheels are installed on the upper end of the compression spring.

[0009] The support frame is internally fixedly equipped with a vibration isolation cylinder, which is filled with gas. An upper extrusion block is nested on the upper end of the vibration isolation cylinder, and the upper end of the upper extrusion block is fixedly mounted on the upper end of the fixed plate. The support frame is internally equipped with a pneumatic vibration isolation mechanism, and an upper gas sealing ring is installed on the upper end of the vibration isolation cylinder. The inner side of the upper gas sealing ring is installed on the lower surface of the upper extrusion block.

[0010] Furthermore, the quick assembly / disassembly mechanism includes a locking pin installed inside the guide wheel, and a guide post is fixedly installed at the lower end of the locking pin. The guide post at the lower end of the locking pin is installed through the guide wheel, and the lower end of the locking pin is installed on the upper end of the compression spring.

[0011] Furthermore, the upper end of the clamping post is provided with a clamping head, and the lower left side of the vibration isolation pad is provided with a device hole, and a clamping plate is fixedly installed inside the device hole on the lower left side of the vibration isolation pad, and the clamping head at the upper end of the clamping post cooperates with the clamping plate.

[0012] Furthermore, the vibration isolation mechanism includes a lower extrusion block nested at the lower end of the vibration isolation cylinder, and a lower body sealing ring is installed at the lower end of the vibration isolation cylinder. The inner side of the lower body sealing ring is installed on the lower surface of the lower extrusion block. Moreover, a movable block is slidably installed at the right end of the support frame. Two movable blocks are distributed symmetrically around the vibration isolation cylinder.

[0013] Furthermore, a buffer spring is installed on the left end of the movable block, and the right end of the buffer spring is installed inside the right end of the support frame. A shock-absorbing rod is rotatably installed on the front end of the movable block, and a shock-absorbing cylinder is rotatably installed on the lower right side of the fixed plate.

[0014] Furthermore, the shock absorber cylinder is filled with shock absorber oil, and the left end of the shock absorber rod is installed through the inside of the shock absorber cylinder. A movable plug is installed inside the shock absorber cylinder, and a guide hole is provided on the movable plug.

[0015] Furthermore, the right end of the movable plug is fixedly installed on the left end of the shock absorber rod, and a shock absorber spring is installed on the left end of the movable plug. The shock absorber spring is fixedly installed inside the left end of the shock absorber cylinder. An oil seal ring is installed on the right end of the shock absorber cylinder, and the inner side of the oil seal ring is installed on the lower surface of the shock absorber rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the vibration isolator with easy replacement of rubber pads;

[0017] 1. When the vibration isolation pad is damaged after long-term use, the user presses the four corners of the vibration isolation pad. The internal clamping plate of the vibration isolation pad will press the clamping post inside the fixing plate. The clamping post will evenly squeeze the compression spring. The compression spring is compressed and squeezes downward. The guide post at the lower end of the clamping post and the guide wheel cooperate to rotate, so that the clamping post rotates 90 degrees. The clamping head at the upper end of the clamping post is released from the clamping plate. The vibration isolation pad can then be replaced. Simply press the button or perform a simple and intuitive operation to easily complete the disassembly and installation of the rubber vibration isolation component in a short time.

[0018] Furthermore, the introduction of the quick-release compression device makes the replacement of rubber vibration isolation components more convenient than ever before. Operators do not need to have advanced technical knowledge or rely on professional tools, which shortens the equipment maintenance time, reduces maintenance costs, and significantly reduces equipment downtime. This effectively ensures the continuity and efficiency of production and avoids huge economic losses caused by long-term downtime.

[0019] Furthermore, it significantly reduces maintenance costs, eliminating the need to hire expensive professional technicians and saving a lot of human and material resources. This convenient replacement method also improves the availability and flexibility of the equipment. Enterprises can maintain and replace rubber vibration isolation components more promptly according to production needs and equipment operating conditions, ensuring that the equipment is always in optimal operating condition and further improving production efficiency.

[0020] 2. The fixed plate presses against the upper pressing block, which in turn presses against the vibration isolation cylinder inside the support frame. The lower pressing block at the bottom works together with the upper pressing block to press against the gas inside the vibration isolation cylinder. The use of advanced pneumatic vibration isolation technology significantly improves the vibration isolation effect. When faced with strong external vibration, it can quickly and effectively absorb and disperse vibration energy, providing excellent protection for the protected equipment.

[0021] Furthermore, the damping cylinder at the upper end of the upper extrusion block is compressed downwards, causing the damping rod to push the movable plug. The movable plug compresses the damping oil inside the damping cylinder and also compresses the damping spring. The extrusion force of the damping cylinder pushes the damping rod, which in turn pushes the moving block on the right side inside the support frame. The moving block compresses the buffer spring, which ensures the stability and accuracy of the protected equipment, extends its service life, and reduces the frequency of equipment maintenance and replacement, thereby saving a lot of costs.

[0035] When the vibration isolation pad 3 is damaged after long-term use, the user presses the four corners of the vibration isolation pad 3, the vibration isolation pad 3 deforms, the clamping plate 10 inside the vibration isolation pad 3 will press the clamping post 9 inside the fixing plate 2, the clamping post 9 will evenly squeeze the compression spring 4, the compression spring 4 is compressed and thus squeezed downward, the guide post at the lower end of the clamping post 9 cooperates with the guide wheel 5 to rotate, so that the clamping post 9 rotates 90 degrees.
