Description

Technical Field

[0001] This utility model relates to the field of vibration isolators, specifically a vibration isolator having a helical spring and an actuator. Background Technology

[0002] A vibration isolator is a device used to reduce and eliminate vibrational forces transmitted from equipment to the foundation and vibrations transmitted from the foundation to the equipment. Specifically, a vibration isolator is an elastic element connecting the equipment and the foundation, mainly working through a spring-damping system. By precisely designing the stiffness of the spring and the resistance of the damper, vibration isolation can be achieved over a wider frequency range. The actuator, as a key component of the active vibration isolation system, converts electrical signals such as voltage or current transmitted by the controller and driver into strain, displacement, and driving force required by the mechanical system, thereby achieving dynamic control force to counteract vibration.

[0003] However, the existing vibration isolators are difficult to disassemble and assemble, and can only absorb vibration forces in the single longitudinal direction, with poor absorption effect on horizontal vibrations. Utility Model Content

[0004] The purpose of this invention is to provide a vibration isolator with a helical spring and an actuator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration isolator with a helical spring and an actuator, comprising a base and a top plate. Connecting plates are fixedly connected to both sides of the base. A bearing plate is fixedly connected to one end of each connecting plate. A traction plate is slidably sleeved on the top of the bearing plate. One end of the traction plate is fixedly connected to the outer wall of the top plate. Multiple mounting plates are fixedly connected to the base. Helical springs are mounted on each of the mounting plates. An assembly plate is fixedly connected to the top of each helical spring. An actuator is fixedly connected to the top of the base. A threaded rod is fixedly connected to the top of the assembly plate and the actuator. The threaded rod passes through the top plate and is threadedly sleeved with a nut. A sliding opening is provided on the bearing plate. A guide plate is slidably connected within the sliding opening. One end of the guide plate has a beveled section. A vertical plate is fixedly connected to the other end of the guide plate. Telescopic springs are fixedly connected between both ends of the vertical plate and the bearing plate. A pressure rod is fixedly connected to the bottom of the traction plate.

[0006] Preferably, the top of the top plate is fixedly connected to two L-shaped angle steel plates arranged opposite to each other, and each of the two L-shaped angle steel plates is provided with a fixing opening.

[0007] Preferably, a base is fixedly connected to the bottom of the base, and the base has mounting holes at all four corners.

[0008] Preferably, the bottom end of the pressure bar is provided with an arc-shaped structure.

[0009] Preferably, the actuator is a pneumatic actuator.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This vibration isolator, which includes a helical spring and an actuator, uses a mounting plate to fix the helical spring and an actuator to be mounted on a base. The top plate is fitted onto each threaded rod, and then nuts are tightened to fix the helical spring and actuator. At the same time, traction plates on both ends of the top plate are fitted onto a bearing plate. When the helical spring is compressed, the pressure rod on the bottom of the traction plate moves down and presses against the inclined section of the guide plate. At this time, the guide plate slides on the bearing plate and pushes the vertical plate. The vertical plate then pulls the telescopic spring, which absorbs lateral vibration. The components of this invention are easy to assemble and disassemble, making it convenient for subsequent use, storage, and transportation. It can also absorb and reduce lateral vibration forces.
