Technical Field

[0001] The utility model belongs to the technical field of servo electric cylinders, and specifically relates to an explosion-proof cylinder servo electric cylinder. Background Technique

[0002] An explosion-proof cylinder servo electric cylinder is a device that converts the rotational force of a motor into a driving force. Generally, a motor drives a threaded lead screw to rotate, thereby converting the rotational force into a driving force.

[0003] Currently, there are still drawbacks in the actual use of explosion-proof cylinder servo electric cylinders: The existing explosion-proof cylinder servo electric cylinders move by the rotation of the threaded lead screw. Due to the large contact area of the threads, the consumption of lubricating oil increases. If the lubricating oil is consumed completely, the operation of the servo electric cylinder may become unstable due to the increased friction, which may lead to the possibility of cylinder explosion. Generally, the oil inlets of the servo electric cylinders are opened one by one manually, and an oil gun is used to add oil, and then the oil inlets are closed after adding oil. This process is cumbersome, reducing work efficiency and being time-consuming and laborious. Therefore, it needs to be improved. Content of the Utility Model

In order for any person skilled in the art to implement and use the present utility model, the following description is given. In the following description, details are set forth for purposes of explanation. It should be understood that those skilled in the art can recognize that the present utility model can be implemented without using these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the present utility model with unnecessary details. Therefore, the present utility model is not intended to be limited to the embodiments shown, but is consistent with the broadest scope that conforms to the principles and features disclosed in the present application.

[0026] Such as Figures 1 to 7As shown in the figure, the present utility model provides an explosion-proof cylinder servo electric cylinder, which includes an oil tank 1. At the upper end of the oil tank 1, there is an impact rod 2. One end of the impact rod 2 close to the oil tank 1 passes through the oil tank 1 and extends into the interior of the oil tank 1. A rotating disk 4 is threadedly connected to the outer side of the impact rod 2. On the bottom surface of the inner cavity of the oil tank 1, a rotating groove 9 is provided. Inside the rotating groove 9, there are two symmetrically arranged throttle valves 8, and the throttle valves 8 are rotatably connected to the rotating groove 9 through a rotating shaft. The impact rod 2 is movably connected to the throttle valves 8. Below the oil tank 1, there is a servo electric cylinder body 16, and the lower end of the oil tank 1 is fixedly communicated with the oil inlet of the servo electric cylinder body 16.

[0027] Adopting the above scheme: Manually press the impact rod 2, so that the lower end of the impact rod 2 contacts the throttle valves 8, thereby opening the throttle valves 8 and allowing the lubricating oil inside the oil tank 1 to enter the interior of the servo electric cylinder body 16 from the lower end of the oil tank 1, and then completing the lubrication of the servo electric cylinder body 16. While the impact rod 2 moves, it drives the rotating disk 4 to rotate through the thread, and then the rotating disk 4 stirs the lubricating oil inside the oil tank 1, making the grease evenly mixed and improving the lubrication effect.

[0028] As Figures 3 to 5 shown in the figure, on the side of the rotating disk 4 away from the throttle valves 8, there is a fixed disk 3. The fixed disk 3 is rotatably connected to the rotating disk 4, and the fixed disk 3 is fixedly connected to the inner cavity wall of the oil tank 1. On the side of the rotating disk 4 away from the fixed disk 3, several stirring blades 6 are rotatably connected.

[0029] Adopting the above scheme: Through the mutual cooperation between the rotating disk 4 and the stirring blades 6, when the rotating disk 4 rotates on the surface of the fixed disk 3, it drives the stirring blades 6 to rotate, increasing the stirring area and improving the lubrication effect of the lubricating oil.

[0030] As Figures 1 to 5 shown in the figure, at one end of the impact rod 2 away from the throttle valves 8, a pressure disk 11 is fixedly connected. On one side of the pressure disk 11, a rectangular groove is provided. On the side of the oil tank 1 close to the rectangular groove, there is a closing disk 12, and the pressure disk 11 is movably connected to the outer surface of the closing disk 12 through the rectangular groove.

[0031] Adopting the above scheme: By setting the mutual cooperation between the pressure disk 11 and the closing disk 12, when manually pressing the pressure disk 11, the closing disk 12 limits the pressure disk 11 to prevent the pressure disk 11 from rotating.

[0032] As Figures 3 to 5 shown in the figure, at one end of the impact rod 2 close to the throttle valves 8, a limiting disk 5 is fixedly connected. The side of the limiting disk 5 away from the throttle valves 8 is movably connected to the rotating disk 4. A return spring 15 is arranged on the outer side of the impact rod 2. The pressure disk 11 is elastically connected to the oil tank 1 through the return spring 15.

[0033] Adopt the above solution: Let the operator reset through the return spring 15 after pressing the pressure plate 11, and at the same time, let the limit disk 5 limit the impact rod 2 after resetting to prevent the impact rod 2 from deviating from the inside of the fuel tank 1, making the operation of the impact rod 2 more stable.

[0034] As Figure 2 and Figure 6 shown, on one side of the inner cavity of the fuel tank 1 close to the rotating groove 9, a fixed block 7 is fixedly connected, and a volute spring is arranged inside the fixed block 7. The throttle 8 is elastically connected to the fixed block 7 through the volute spring.

[0035] Adopt the above solution: Set the mutual cooperation of the fixed block 7 and the throttle 8, so that the throttle 8 can be reset through the volute spring after rotation, thereby completing the closing of the fuel tank 1 and preventing the lubricating oil from running out of the inside of the fuel tank 1.

[0036] As Figure 2 and Figure 7 shown, on one side of the fuel tank 1 away from the servo electric cylinder body 16, a fuel filling port is arranged. On one side of the fuel tank 1 close to the fuel filling port, a limit block 10 is fixedly arranged. An inner side of the limit block 10 is movably connected with a closing disk 12. The closing disk 12 is rotationally connected to the limit block 10 through a straight shaft, and the closing disk 12 is movably connected with the fuel filling port.

[0037] Adopt the above solution: Set the mutual cooperation of the limit block 10 and the closing disk 12 to close or open the fuel filling port of the fuel tank 1, reducing the entry of other impurities other than non-lubricating oil into the inside of the fuel tank 1 and affecting the lubrication effect.

[0038] As Figure 7 shown, on one side of the limit block 10 away from the straight shaft, a clamping column 14 is arranged. The clamping column 14 passes through the limit block 10 and is clamped with the closing disk 12. One end of the clamping column 14 away from the closing disk 12 is fixedly connected with a pulling column 13. A threaded spring is arranged on the outer side of the clamping column 14. The pulling column 13 is elastically connected to the limit block 10 through the threaded spring.

[0039] Adopt the above solution: Limit the closing disk 12 by setting the mutual cooperation of the closing disk 12 and the clamping column 14 to prevent the closing disk 12 from moving in the closed state and enhancing the closing effect of the closing disk 12.

[0040] The working principle and usage process of the present utility model: When in use, first pull the pulling column 13 to rotate the closing disc 12, exposing the oil inlet. After manually adding lubricating fluid into the fuel tank 1, then reset the closing disc 12 to close the fuel tank 1. When the servo electric cylinder body 16 needs lubrication, let the operator pat the pressure plate 11, so that the pressure plate 11 drives the impact rod 2 to impact the throttle 8. During the impact of the impact rod 2, the impact rod 2 will drive the rotating disc 4 and the stirring blade 6 to rotate, thereby enabling the stirring blade 6 to stir the lubricating oil, making the grease evenly mixed, improving the lubrication effect of the lubricating oil. Then let the impact rod 2 open the throttle 8, so that the lubricating oil inside the fuel tank 1 enters the servo electric cylinder body 16 to complete lubrication. Immediately afterwards, after the impact rod 2 resets, the volute spring will push the throttle 8 to reset, thereby closing the fuel tank 1 to prevent all the lubricating oil from flowing into the servo electric cylinder body 16.

Therefore, the appended claims are intended to be construed as including the preferred embodiments as well as all changes and modifications falling within the scope of the present utility model.

[0042] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
