Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic actuators, in particular to an opening and closing buffering type pneumatic actuator. Background Art

[0002] Pneumatic actuators are common industrial automation devices. They utilize compressed air as a power source, converting air pressure into mechanical energy to drive various valves and actuators. Due to their high efficiency, reliability, and explosion-proof properties, these devices are widely used across multiple industries.

[0003] The working principle of pneumatic actuators is relatively simple and efficient. When compressed air enters the air chamber of the pneumatic actuator, the air pressure pushes the piston or diaphragm to move, thereby driving the push rod or rotating shaft connected to them. However, when the piston moves to open and close, there is a lack of a buffering function for the piston. As a result, the gas may drive the piston to move rapidly, causing the piston to have a certain impact on the internal components of the pneumatic actuator, thereby affecting the service life of the pneumatic actuator.

For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0026] The utility model provides the following technical solutions:

[0027] Example 1

[0028] Combine Figures 1 to 5 , an opening and closing buffer type pneumatic actuator, comprising an actuator body 1, an opening buffer mechanism 2 is provided inside the actuator body 1, and a closing buffer mechanism 3 is provided on one side of the opening buffer mechanism 2;

[0029] The opening buffer mechanism 2 includes a long box 21, which is fixedly connected to the inner wall of the actuator body 1, and a spring 22 is fixedly connected to the inner wall of the long box 21. The end of the spring 22 away from the long box 21 is fixedly connected to a rectangular block 23, and one side of the rectangular block 23 is fixedly connected to a support block 24. A movable plate 25 is provided inside the support block 24, and a support plate 26 is provided on one side of the movable plate 25. A circular plate 27 is fixedly connected to the left side of the support plate 26.

[0030] Furthermore, a moving opening is opened on one side of the long box 21, and the support block 24 passes through the moving opening, so that the long box 21 can move stably through the moving opening.

[0031] Furthermore, the support block 24 is fixedly connected to the interior of the short shaft 1, and the movable plate 25 is rotatably connected to the outer wall of the short shaft 1, so that the movable plate 25 can drive the support block 24 to move through the short shaft 1.

[0032] Furthermore, the support plate 26 is fixedly connected to the interior of the short shaft 2, and the movable plate 25 is rotatably connected to the outer wall of the short shaft 2, so that the circular plate 27 can push the movable plate 25 to move through the mutual cooperation of the support plate 26 and the short shaft 2.

[0033] Example 2

[0034] See Figures 1 to 5 On the basis of the first embodiment, the closing buffer mechanism 3 is further obtained to include a fixed block 31, the fixed block 31 is fixedly connected to the inner wall of the long box 21, a fixed cylinder 32 is fixedly connected to the side of the fixed block 31 away from the long box 21, a spring 2 33 is fixedly connected to the inner wall of the fixed cylinder 32, one end of the spring 2 33 is fixedly connected to a round block 34, and one side of the round block 34 is fixedly connected to a long shaft 35, which can serve the purpose of buffering when closing.

[0035] Furthermore, a circular hole is opened on one side of the fixing cylinder 32 , and the long shaft 35 passes through the circular hole and moves, so that the long shaft 35 can move through the circular hole.

[0036] Furthermore, the second spring 33 is sleeved on the outer wall of the long shaft 35 , and the round block 34 is slidably connected to the inner wall of the fixed cylinder 32 , so that the round block 34 can move stably.

[0037] Furthermore, the long shaft 35 is fixedly connected to one side of the rectangular block 23 , and the rectangular block 23 is slidably connected to the inner wall of the long box 21 .

[0038] During actual operation, when this device is used, after gas is injected into the interior of the actuator body 1, the piston can move toward the direction close to the circular plate 27. When the piston moves, it can push the circular plate 27 to move. The circular plate 27 can push the rectangular block 23 to move through the mutual cooperation of the support plate 26, the movable plate 25 and the support block 24. At the same time, the rectangular block 23 can compress the spring 1 22. Then, when it is opened, under the action of the sliding friction of the rectangular block 23 and the elasticity of the spring 1 22, it can play a buffering role, reduce the impact of the piston moving too fast on the internal components of the actuator body 1, ensure the further development of the actuator body 1, and extend the service life of the actuator body 1.

[0039] When the actuator body 1 needs to be closed, the piston no longer presses the circular plate 27, and the movement of the rectangular block 23 will also drive the long shaft 35 to move. The long shaft 35 can drive the circular block 34 to move and compress the spring 2 33, so that when closing, the circular block 34 can slide on the inner wall of the fixed cylinder 32, and under the elastic action of the spring 2 33, it can buffer the closing process, ensuring that the closing work can be carried out stably, so that the actuator body 1 can work stably and enhance the practicality of the device.
