Description

Technical Field

[0001] This utility model relates to the field of electric actuator technology, and in particular to a shock-resistant electric actuator. Background Technology

[0002] Electric actuators are an essential component of automatic control systems. Their function is to receive control signals from the controller, change the magnitude of the controlled medium, and thus maintain the controlled variable at the required value or within a certain range. Actuators can be classified into three main categories according to their energy source: pneumatic, hydraulic, and electric. Pneumatic actuators use compressed air as their energy source and are characterized by simple structure, reliable and stable operation, large output thrust, convenient maintenance, fire and explosion protection, and low price. Therefore, they are widely used in chemical, papermaking, and oil refining production processes.

[0003] Most electric actuators on the market currently vibrate during startup, which can cause malfunctions and shorten their lifespan due to prolonged use. Furthermore, existing electric actuators lack sound insulation and noise reduction features, easily polluting the working environment. Therefore, a vibration-resistant electric actuator is needed to meet these user needs. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the fact that most electric actuators on the market currently exist, as described above or in the prior art, vibrate when starting up, which causes the electric actuator to malfunction due to long-term vibration during use, thus affecting the service life of the electric actuator. At the same time, existing electric actuators do not have sound insulation and noise reduction functions during long-term use, which can easily pollute the working environment. Therefore, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a shock-resistant electric actuator.

[0012] As a preferred embodiment of the anti-vibration electric actuator of this utility model, the anti-vibration plate assembly includes a buffer layer, elastic rubber and an anti-vibration layer. The anti-vibration plate assembly is integrally formed by hot pressing the buffer layer, elastic rubber and anti-vibration layer.

At the same time, the mounting column and the mounting groove are interlocked, and the bolt rod body is threadedly connected to the second and first threaded holes respectively.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1: Refer to Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a shock-resistant electric actuator, which can address the common problem of most electric actuators on the market vibrating during startup, causing malfunctions due to prolonged vibration and affecting their service life. Furthermore, existing electric actuators lack sound insulation and noise reduction functions during long-term use, easily causing pollution to the working environment. The actuator includes an electric actuator body 1 and a sealing cover 2. The top of the electric actuator body 1 cooperates with the sealing cover 2. A first installation / removal assembly 3 is installed on the outer wall of the sealing cover 2. A shock-resistant plate assembly 5 is installed on the top of the sealing cover 2. A second installation / removal assembly 4 is installed on the outer wall of the electric actuator body 1. A sound-absorbing plate assembly 6 is installed at the bottom of the sealing cover 2.

[0029] Combination Figure 1 , Figure 2 and Figure 3In an embodiment of this utility model, the first installation and disassembly assembly 3 includes a welding plate 301, which is welded to the side wall of the sealing cover plate 2. The side wall of the welding plate 301 is equipped with an installation post 302, and the outer wall of the installation post 302 is provided with a first threaded hole 303. The installation post 302 is tightly fitted to the inner wall of the installation groove 402.

[0030] Combination Figure 2 , Figure 4 and Figure 5 In an embodiment of this utility model, the second installation and disassembly assembly 4 includes a fixing seat 401, which is welded to the outer wall of the electric actuator body 1. The top of the fixing seat 401 is provided with an installation groove 402, and the outer wall of the fixing seat 401 is provided with a second threaded hole 403. The inner thread of the second threaded hole 403 is connected to a bolt rod body 404.

[0031] Combination Figure 2 , Figure 4 and Figure 5 In an embodiment of this utility model, the anti-vibration plate assembly 5 includes a buffer layer 501, an elastic rubber 502, and an anti-vibration layer 503. The anti-vibration plate assembly 5 is integrally formed by hot pressing the buffer layer 501, the elastic rubber 502, and the anti-vibration layer 503. Elastic plates 5011 are installed in a horizontal arrangement inside the buffer layer 501, and each elastic plate 5011 is provided with an elastic ball 5012. Reinforcing ribs 5031 are installed in a horizontally staggered arrangement inside the anti-vibration layer 503, and the reinforcing ribs 5031 are made of glass fiber.

[0032] The specific working principle is as follows: when the electric actuator is started and vibration is generated, the design of the elastic plate 5011 and multiple sets of elastic balls 5012 allows the vibration-damping plate assembly 5 to absorb the vibration through deformation of the elastic plate 5011 and elastic balls 5012. At the same time, the design of the reinforcing ribs 5031, which are arranged in an interlaced manner and installed inside the vibration-damping layer 503, improves the vibration-damping effect of the vibration-damping plate assembly 5.

[0033] Example 2: Refer to Figures 1-5This is the first embodiment of the present invention. This embodiment provides a shock-resistant electric actuator, which can solve the problem of most electric actuators on the market. Because electric actuators generate vibration when they start up, they will malfunction due to long-term vibration during use, thus affecting the service life of the electric actuator. At the same time, existing electric actuators do not have sound insulation and noise reduction functions during long-term use, which can easily cause pollution to the working environment. The sound-absorbing panel assembly 6 includes a rubber plastic plate 601, which is fixedly installed at the bottom of the sealing cover plate 2. The rubber plastic plate 601 is tightly attached to the inner wall of the electric actuator body 1.

[0035] The specific working principle is as follows: First, through the design of the rubber plastic plate 601, and through the design of multiple sets of first sound-absorbing holes 602 and second sound-absorbing holes 603, the first sound-absorbing holes 602 and second sound-absorbing holes 603 are connected through the second sound-absorbing holes 603 and the first connecting hole 604, so that the noise generated by the electric actuator is absorbed through the first sound-absorbing holes 602 and second sound-absorbing holes 603, thereby improving the sound insulation effect of the electric actuator.
