Description

Technical Field

[0001] This utility model relates to the field of speed control actuators, specifically a precision-controlled, vibration-resistant speed control actuator. Background Technology

[0002] In fields such as industrial automation, transportation equipment, and construction machinery, speed control actuators are the core components for achieving precise control of equipment speed, and their operational stability directly determines the working accuracy and safety performance of the entire machine.

[0003] Actuators are susceptible to continuous vibration or impact loads during operation. Traditional precision speed control actuators lack targeted anti-vibration buffer design, and external vibration loads are directly transmitted to internal precision components. Under long-term action, this can easily lead to component loosening, poor contact, or even component breakage and short circuits. This not only interrupts equipment operation but also increases maintenance costs and downtime. Therefore, it is necessary to design a precision anti-vibration speed control actuator to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a precision-controlled, anti-vibration, speed-regulating 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 precision-controlled anti-vibration speed-regulating actuator, comprising an actuator body, a guide cylinder fixedly installed on both the top and bottom surfaces of the actuator body, a sliding cylinder slidably installed through the inner side of the guide cylinder, a top plate fixedly installed at the end of the sliding cylinder away from the guide cylinder, and an elastic element provided between the guide cylinder and the sliding cylinder; The bottom of the sliding cylinder is bonded with a contact pad, the outside of the guide cylinder is connected with an anti-vibration component for absorbing vibration energy, and the outside of the top plate is bonded with multiple protective pads.

[0006] Preferably, the seismic stabilizing component includes multiple damping rods, which are fixedly installed on the outside of the guide cylinder. A rotating plate is rotatably installed at one end of each damping rod, and the end of the rotating plate away from the damping rod is rotatably installed on the inside of the top plate.

[0007] Preferably, both the guide cylinder and the sliding cylinder have rectangular cross-sections, and the damping rods are installed at equal intervals on the outer side of the guide cylinder.

[0008] Preferably, the elastic element is a spring, one end of which is installed inside the sliding cylinder, and the other end of which is fixedly installed inside the guide cylinder. The spring passes through the guide cylinder and the inner side of the sliding cylinder.

[0009] Preferably, a gasket is adhered to the surface of the top plate, and the gasket is made of rubber.

[0010] Preferably, corner pads are adhered to the outer corners of the actuator body, and the corner pads are made of silicone material.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This precision-controlled anti-vibration speed-regulating actuator protects the outer corners of the actuator body with multiple corner pads. During use, external impacts and vibrations act on the pads, causing the top plate to move closer to the actuator body. The top plate pushes the rotating plate to rotate, which causes the damping rod to contract, thereby absorbing vibration energy and achieving an anti-vibration effect. During reset, the spring pushes the sliding cylinder to move away from the actuator body, which in turn moves the top plate, causing the rotating plate and damping rod to reset.

[0012] 2. When the gasket and top plate are subjected to a large impact, and the sliding cylinder approaches the actuator body to its limit position, the contact pad can block the sliding cylinder from the guide cylinder, preventing the sliding cylinder from directly hitting the guide cylinder and causing damage to the components, thus improving the safety of the device. The gasket provides buffer protection for the top surface of the top plate, and the protective pad provides buffer protection for the sides of the top plate. Attached Figure Description

[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] Example 1 Please refer to Figure 1-3 As shown, this utility model provides a precision-controlled anti-vibration speed-regulating actuator, including an actuator body 1. A guide cylinder 3 is fixedly installed on the top and bottom surfaces of the actuator body 1. A sliding cylinder 4 is slidably installed through the inner side of the guide cylinder 3. A top plate 5 is fixedly installed at the end of the sliding cylinder 4 away from the guide cylinder 3. An elastic element is provided between the guide cylinder 3 and the sliding cylinder 4. The bottom of the sliding cylinder 4 is bonded with a contact pad 8, the outside of the guide cylinder 3 is connected with an anti-vibration component for absorbing vibration energy, and the outside of the top plate 5 is bonded with multiple protective pads 11.

[0017] Specifically, vibration or impact is applied to the top plate 5, causing the top plate 5 to move, thereby enabling the anti-vibration component to play an anti-vibration role, protecting the actuator body 1 and its internal components. The protective pad 11 protects the outside of the top plate 5, and the contact pad 8 can separate the guide cylinder 3 and the sliding cylinder 4 to prevent the sliding cylinder 4 from directly impacting the guide cylinder 3.

[0018] The anti-seismic component includes multiple damping rods 9, which are fixedly installed on the outside of the guide cylinder 3. A rotating plate 10 is rotatably installed at one end of the damping rod 9, and the end of the rotating plate 10 away from the damping rod 9 is rotatably installed on the inside of the top plate 5. The cross-sections of the guide cylinder 3 and the sliding cylinder 4 are both rectangular. The damping rods 9 are installed at equal intervals on the outside of the guide cylinder 3. External impacts and vibrations act on the top plate 5, causing the top plate 5 to move towards the actuator body 1. The top plate 5 pushes the rotating plate 10 to rotate, thereby causing the damping rods 9 to contract, thus absorbing vibration energy and achieving an anti-seismic effect.

[0019] Specifically, the elastic element is a spring 6. One end of the spring 6 is installed inside the sliding cylinder 4, and the other end of the spring 6 is fixedly installed inside the guide cylinder 3. The spring 6 passes through the guide cylinder 3 and the inner side of the sliding cylinder 4. The spring 6 supports the sliding cylinder 4 and works in conjunction with multiple damping rods 9 to perform anti-vibration work. When the top plate 5 is not subjected to external impact force, the spring 6 pushes the sliding cylinder 4 to reset the top plate 5.

[0020] Among them: a gasket 7 is bonded to the surface of the top plate 5. The gasket 7 is made of rubber. When external vibration or impact acts on the surface of the gasket 7, the gasket 7 protects the top plate 5.

[0021] Among them: corner pads 2 are glued to the outer corners of the actuator body 1. The corner pads 2 are made of silicone material and protect the outer corners of the actuator body 1.

[0022] Working principle: This utility model is a precision-controlled anti-vibration speed-regulating actuator. Multiple corner pads 2 protect the outer corners of the actuator body 1. When in use, external impacts and vibrations act on the pads 7, causing the top plate 5 to move closer to the actuator body 1. The top plate 5 pushes the rotating plate 10 to rotate, thereby causing the damping rod 9 to contract, thus absorbing vibration energy and achieving an anti-vibration effect. When resetting, the spring 6 pushes the sliding cylinder 4 to move away from the actuator body 1, thereby causing the top plate 5 to move. The top plate 5 drives the rotating plate 10 and the damping rod 9 to reset. When the gasket 7 and the top plate 5 are subjected to a large impact, when the sliding cylinder 4 approaches the actuator body 1 to the limit position, the contact pad 8 can block the sliding cylinder 4 from the guide cylinder 3, preventing the sliding cylinder 4 from directly hitting the guide cylinder 3 and causing damage to the components, thus improving the safety of the device. The gasket 7 provides buffer protection for the top surface of the top plate 5, and the protective pad 11 provides buffer protection for the side surface of the top plate 5.
