[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] A high-frequency cylinder, such as Figures 1-8 As shown, the device includes a cylinder body 1, typically made of high-strength aluminum alloy through precision machining to achieve lightweight construction. A valve body 2 is mounted on the cylinder body 1. A cylindrical cavity 12 is formed inside the cylinder body 1, and a piston 4 is slidably mounted inside the cavity 12. An output rod 5 is fixed to one end of the piston 4, passing through the front end of the cylinder body 1 and sliding with the front end of the cylinder body 1, outputting the linear motion of the piston 4 to an external load. The output rod 5 is made of hard alloy. An air inlet 3 is formed at one end of the cylinder body 1, and a pipeline system is formed inside the cylinder body 1. One end of the pipeline system is connected to the air inlet 3, and the other end is connected to the cavity 12. The valve body 2 is used to control the pipeline system to charge or evacuate air from the cavity 12. When gas enters the pipeline system through the air inlet 3, the valve body 2 opens the pipeline, allowing gas to enter the cavity 12 and push the piston 4 to drive the output rod 5 to slide. Conversely, when the valve body 2 closes the pipeline, the gas in the cavity 12 is evacuated through the pipeline system and discharged from the air inlet 3, causing the piston 4 to drive the output rod 5 to operate at a high frequency.
[0028] The cylinder body 1 has a groove 6, and a sealing gasket 7 is snapped into the groove 6. The sealing gasket 7 is pressed and installed between the cylinder body 1 and the valve body 2 to ensure that the three ports of the valve body 2 are independent and sealed from the connection port of the cylinder body 1, preventing the three ports of the valve body 2 from being connected and preventing air leakage between the valve body 2 and the cylinder body 1.
[0029] A fixing plate 8 and a fixing post 9 are fixedly connected to the cylinder body 1. The fixing plate 8 and the fixing post 9 are located at both ends of the cylinder body 1, and the fixing plate 8 and the fixing post 9 are both fitted and inserted into the valve body 2.
[0030] The fixing plate 8 and the fixing column 9 are fitted and inserted into the corresponding slots on the valve body 2 to ensure that the valve body 2 is accurately positioned when it is bolted, to avoid misalignment and to enhance the connection rigidity, while also facilitating accurate alignment of the sealing gasket 7.
[0031] Example 1: As Figures 1-3 As shown, a set of valve bodies 2 are installed directly on the upper surface of cylinder body 1. The piping system includes pipe 10, pipe 21 and connecting port 13. One end of pipe 10 is connected to the air inlet 3, and the other end is connected to one of the working ports of valve body 2. One end of pipe 21 is connected to the other working port of valve body 2, and the other end of pipe 21 is connected to one end of cavity 12 through connecting port 13.
[0032] Working principle: The air inlet 3 is connected to the air source, and the two working ports of the valve body 2 are connected. The air source allows gas to be filled into the air inlet 3, and enters the cavity 12 through pipe 10, valve body 2, pipe 2 11 and connecting port 13, pushing the piston 4 to move and the output rod 5 to extend. The air source draws gas from the air inlet 3, and the compressed air in the cavity 12 is quickly discharged from the air inlet 3 through the original path (connecting port 13, pipe 2 11, valve body 2) (one end of the cavity 12 can be connected to the atmosphere for air replenishment). The piston 4 is reset under the action of external load force or inertial force, and the output rod 5 retracts.
[0033] Example 2: Figures 4-8 As shown, the basic structure of cylinder 1, cavity 12, piston 4, and output rod 5 is similar to that of Embodiment 1. The difference lies in that valve body 2 (two-position three-way valve, the specific working principle of which is existing technology and will not be elaborated further) and air inlet 3 are symmetrically arranged in two sets. The piping system includes a left pipe and a right pipe (as shown in the figure). Figure 4 (The orientation is for example) The left and right pipes are connected at one end to both ends of the cavity 12, and the other end is connected to two sets of air inlets 3. The two sets of valve bodies 2 control the opening and closing of the left and right pipes respectively. The exhaust ports 19 of the two sets of valve bodies 2 are connected to two sets of exhaust ports 19 on the side wall of the cylinder 1 respectively. Small mufflers can be installed on the exhaust ports 19 on the cylinder 1. The left valve body 2 controls the left pipe to fill the rear end of the cavity 12 with air, and the right valve body 2 controls the right pipe to fill the front end of the cavity 12 with air, and controls the piston 4 to drive the output rod 5 to move.
[0034] The left pipe includes air passage 14, air passage 2 15 and connecting port 2 16, which are responsible for supplying and exhausting air to the rear end of the cavity 12. One end of air passage 14 is connected to the air inlet 3 located on the left side, and the other end is connected to the air inlet working port of the valve body 2 located on the left side. One end of air passage 2 15 is connected to another set of working ports of the valve body 2 located on the left side, and the other end is connected to connecting port 2 16. The end of connecting port 2 16 is connected to the rear end of the cavity 12.
[0035] The right pipeline comprises air passage three 17 and air passage four 18, which are responsible for supplying and discharging air to the front end of the cavity 12, the air passage three 17 is communicated with the front end of the cavity 12 at one end and communicated with the air inlet working port of the valve body 2 located at the right side at the other end, and the air passage four 18 is communicated with another working port of the valve body 2 located at the right side at one end and communicated with the air inlet 3 located at the right side at the other end.
[0036] Working principle:
[0037] The air inlet working port of the right valve body 2 is closed, another working port and the right air outlet 19 are opened, the air inlet working port and another working port of the left valve body 2 are opened, and the left air outlet 19 is closed, the air enters from the left air inlet 3, passes through the air passage one 14, the left valve body 2, the air passage two 15 and the communication port two 16, enters the rear end of the cavity 12, drives the piston 4 to move forward, and the output rod 5 is stretched out, at the same time, the air at the front end of the cavity 12 is extruded, passes through the air passage three 17, the right valve body 2 (at this time, the exhaust function is opened) and the right air outlet 19 and is discharged.
[0038] The air inlet working port of the left valve body 2 is closed, another working port and the left air outlet 19 are opened, the air inlet working port and another working port of the right valve body 2 are opened, and the right air outlet 19 is closed, the air enters from the right air inlet 3, passes through the air passage four 18, the right valve body 2 and the air passage three 17, enters the front end of the cavity 12, drives the piston 4 to move backward, and the output rod 5 is retracted, at the same time, the air at the rear end of the cavity 12 passes through the communication port two 16, the air passage two 15, the left valve body 2 and the left air outlet 19 and is discharged.
[0039] The symmetrical design provides the air cylinder with completely independent and shortest high-speed charging and discharging channels, so that the piston 4 can obtain extremely high acceleration and movement speed in both stretching out and retracting directions, and high-frequency and high-speed movement is realized.
[0040] The working principle of the high-frequency air cylinder is as follows:
[0041] The internal pipeline system of the cylinder body 1 replaces the external air pipe, the shortest pneumatic path is realized, the installation space of the equipment is not occupied, the charging and discharging speed is high, the system response delay effect is almost eliminated, the overall operation efficiency of the air cylinder is improved, the air cylinder operates at high frequency, and the whole is light in weight.
[0042] The basic principle, main features and advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principle of the utility model, and various changes and improvements can be made without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model.
