Description

Technical Field

[0002] The emergence of reverse pneumatic-hydraulic booster cylinders is to meet the demand for actuators with reverse high pressure, compact structure and efficient power transmission in fields such as automation equipment. It replaces some traditional combinations of pneumatic cylinders and hydraulic devices, and improves the power output performance and integration of equipment under special working conditions such as reverse clamping and pushing.

[0003] The main structure of the reverse pneumatic-hydraulic booster cylinder consists of a pre-compression cylinder, a booster cylinder, an oil reservoir, and a piston assembly. Its working principle is as follows: when compressed air is introduced into the pre-compression inlet, it pushes the piston in the pre-compression cylinder to move, causing the piston rod connected to it to extend, thus realizing the pre-compression action. At this time, the hydraulic oil in the oil reservoir enters the booster cylinder through the oil circuit under the action of air pressure, pushing the piston in the booster cylinder to move and boosting the hydraulic oil. The boosted hydraulic oil pushes the working piston to extend in the reverse direction, outputting strong pressure and completing the working task.

[0004] When using existing reverse gas-liquid booster cylinders, some booster cylinders must be installed vertically. The booster cylinders themselves are large in size and cannot be used to apply reverse tension on the same axis, which increases labor costs and time and reduces efficiency. Therefore, the reverse gas-liquid booster cylinder is proposed to solve the above problems. Utility Model Content

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, compressed air is introduced through the air source connector, first passing through the regulating valve, and then through the normally open air passage of the rotary air source switch valve. The air pressure can be set by adjusting the knob. The compressed air then enters the depressurization space through the depressurization pipe, pushing the air piston and the booster piston to their initial positions. Activating the rotary air source switch valve cuts off the air in the depressurization pipe and simultaneously directs the air pressure to air passage three, the small oil tank, and the booster pipe. Because air passage three has a larger diameter, most of the gas first rushes into the pressure space, pushing the oil-gas separation piston, forcing out the hydraulic oil from the small oil tank. This hydraulic oil then enters the oil storage space through the side hole and slightly moves the booster piston, completing the pre-filling of the oil passage. After pre-filling, all the air pressure flows to the booster pipe and into the booster space, pushing the air piston and cylinder piston rod towards the hydraulic cylinder body. After the piston rod passes the oil sealing ring, a sealed high-pressure space is formed within the hydraulic cylinder body, compressing the hydraulic oil and forcing it into the oil storage space. This pushes the booster piston to generate a strong pulling force, completing one working cycle.

[0020] 2. In this utility model, the first air passage is located inside the booster air pipe, providing a channel for the transmission of booster gas and ensuring its directionality and stability. The second air passage is located inside the depressurization air pipe, responsible for guiding compressed air and realizing the delivery of depressurized gas from the regulating valve to the depressurization space. The third air passage is located inside the connecting air head, where most of the gas can first flow into the pressure space through the third air passage to start the oil pre-charge process. The oil passage is inside the small oil tank, serving as a hydraulic oil flow channel, and working with the oil-gas separation piston to push the hydraulic oil out to the subsequent oil passage. The hydraulic cylinder has an oil storage space and a depressurization space. The oil storage space contains the hydraulic oil delivered from the oil passage. After high-pressure oil is injected, it can push the booster piston to move and generate pulling force. The depressurization space and the depressurization space inside the hydraulic cylinder together receive the gas from the depressurization air pipe, and use air pressure to push the booster piston and the air piston to and maintain their initial positions, ensuring that the cylinder is ready before operation.

[0030] 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.

[0031] Example:

[0032] Reverse gas-liquid booster cylinder, refer to Figures 1 to 3The system includes a connecting air head 1 and a hydraulic cylinder body 11. An oil reservoir plug 2 is fixedly connected to the rear end of the air head 1, sealing the oil storage structure and preventing oil leakage from the connection point. An air passage mechanism 3 is installed inside the hydraulic cylinder body 11, guiding the flow of compressed air within the cylinder body and directly controlling the switching of the cylinder's working state. A small oil reservoir 4 is fixedly connected to the rear end of the air head 1, storing the hydraulic oil required for operation and providing a source of oil for the pressurization process. An oil pipe 5 is fixedly connected to the rear end of the small oil reservoir 4, serving as a channel for hydraulic oil delivery and ensuring oil flow between the small oil reservoir 4 and the hydraulic space. A pneumatic cylinder body 12 is fixedly connected to the rear end of the hydraulic cylinder body 11, forming different pneumatic-hydraulic working spaces in conjunction with the hydraulic cylinder body 11. The cylinder body 12 is equipped with pneumatic drive and hydraulic boosting functions. A pressure reducing pipe 6 is fixedly connected to the outside of the pneumatic cylinder body 12. The pressure reducing pipe 6 is the passage for compressed air to enter the pressure reducing space and is used to keep each piston in the initial position in the initial stage. A boosting pipe 7 is fixedly connected to the outside of the pneumatic cylinder body 12. The boosting pipe 7 is the channel for high-pressure gas to enter the boosting space and provides the air pressure source for generating strong thrust. An oil-gas separation piston 8 is slidably connected inside the small oil tank 4. The oil-gas separation piston 8 can push the hydraulic oil in the small oil tank 4 to output under the action of air pressure, and at the same time realize the effective separation of gas and liquid, so as to avoid gas mixing into the oil and affecting the boosting effect. A pipe connector 9 is fixedly connected to the rear end of the boosting pipe 7. The pipe connector 9 is used to realize the stable connection between the boosting pipe 7 and the pneumatic cylinder body 12 and ensure the sealing of the gas transportation process.

[0033] The air pipe connector 9 is externally fixedly connected to the bottom end of the pneumatic cylinder body 12, connecting the booster air pipe 7 to the booster space 39 inside the pneumatic cylinder body 12. An oil connector 10 is fixedly connected to the rear end of the oil pipe 5, connecting the oil pipe 5 to the oil passage to ensure the sealing and unobstructed flow of the oil. A piston 13 is slidably connected inside the pneumatic cylinder body 12. The piston 13 moves under the pressure of the air in the booster space 39, thereby pushing the cylinder piston rod 14. The piston 13 is slidably connected inside the booster space 39, and its sliding state determines the generation and transmission of thrust during the boosting process. The cylinder piston rod 1 is fixedly connected inside the piston 13. 4. The cylinder piston rod 14, as a force transmission component, transmits the thrust of the air piston 13 to the inside of the hydraulic cylinder 11, triggering hydraulic boosting. The cylinder body connector 15 is slidably connected inside the hydraulic cylinder 11. The cylinder body connector 15 serves to connect the cylinder body components and also ensures the sealing performance of the pressure reduction space 38. The cylinder body connector 15 is externally slidably connected inside the pressure reduction space 38. The cylinder body connector 15 and the cylinder plug sealing ring 21 cooperate to form a sealing structure, ensuring the stability of the air pressure in the pressure reduction space 38. The booster piston 16 is fixedly connected inside the hydraulic cylinder 11. The booster piston 16 moves under the push of the high-pressure oil, ultimately realizing the output of the powerful pulling force of the reverse air-hydraulic booster cylinder.

[0034] The hydraulic cylinder body 11 is internally equipped with a wear-resistant copper ring 17. The wear-resistant copper ring 17 prevents direct hard contact and friction between the booster piston 16, extending its service life and ensuring motion accuracy. The hydraulic cylinder body 11 is internally threaded with a fastening nut 18. The fastening nut 18 cooperates with a connecting screw 19 to assemble and fix the various cylinder components. The front end of the fastening nut 18 is threaded with a connecting screw 19, which is used to connect a screw 29 to the fastening nut 18. The front end of the connecting screw 19 is threaded with a screw 29, which has a helical shape. Its spiral structure is used to move the externally connected components. The front end of the booster piston 16 is threaded with an oil-sealing screw 20, which is used to plug the oil hole on the cylinder body to prevent oil leakage and ensure stable oil pressure inside the hydraulic cylinder body 11. The external thread of the oil-sealing screw 20 is connected to the inside of the hydraulic cylinder body 11, and a reliable seal is achieved through the threaded connection to prevent oil from seeping out from the oil hole. The piston 13 is externally fixedly connected with a cylinder plug seal ring 21, which is externally slidably connected to the inside of the decompression space 38 to provide sealing and pressure reduction. The function of pressure space 38 is to prevent gas leakage from affecting the pressure reduction effect. An oil seal ring 22 is fixedly connected to the outside of cylinder body connector 15. The oil seal ring 22 is externally slidably connected to the inside of pressure reduction space 37 to seal pressure reduction space 37, ensuring that the gas entering this space can effectively push the piston to maintain its initial position. A piston seal ring 23 is fixedly connected to the outside of booster piston 16 to enhance the sealing between booster piston 16 and hydraulic cylinder 11, preventing high-pressure oil leakage during the boosting process. A pressure reducing pipe connector 2 is fixedly connected to the rear end of pressure reducing pipe 6. 4. Used to connect the pressure reducing pipe 6 to the pneumatic cylinder 12, ensuring the stability and sealing of the pressure reducing gas delivery path. The front end of the small oil tank 4 is fixedly connected to a rotary air source switch valve 26. When started, it will immediately cut off the air to the pressure reducing pipe 6 and simultaneously guide the air pressure to the air passage 33, the small oil tank 4, and the booster pipe 7. When reset, it will cut off the booster air passage and reconnect the pressure reducing pipe 6. The rotary air source switch valve 26 is fixedly connected to an external regulating valve 25. Compressed air can pass through this point after entering from the air source connector 28. It is a component that controls the opening and closing of the pressure reducing air passage.

[0035] The front end of the regulating valve 25 is fixedly connected to the regulating knob 27, which allows the operator to set the required air pressure. The pressure will ultimately determine the pulling force after pressurization. The bottom end of the regulating valve 25 is fixedly connected to the air source connector 28, which is the inlet for external compressed air to enter the reverse air-liquid booster cylinder, providing a power source for the device. The rear end of the small oil storage tank 4 is fixedly connected to the connecting pipe 30, which serves as a connection channel between the small oil storage tank 4 and other oil structures, assisting in the transportation and circulation of oil.

[0036] Specifically, compressed air is introduced through the air source connector 28, passes through the regulating valve 25, and the air pressure is set by the regulating knob 27. The gas then enters the depressurization space through the depressurization pipe 6, pushing the air piston 13 and the booster piston 16 to their initial positions and maintaining them there. At this time, no pulling force is generated. After activating the knob air source switch valve 26, the air in the depressurization pipe 6 is cut off, and the air pressure is directed to the air passage 33, the small oil tank 4, and the booster pipe 7. Because the orifice of the air passage 33 is larger, most of the gas first rushes into the air pressure space 34, pushing the oil-gas separation piston 8. The hydraulic oil in the small oil tank 4 is forced out and enters the oil storage space 36 through the side hole, pushing the booster piston 16 to move slightly, completing the pre-filling of the oil passage. After the pre-filling is completed, all the air pressure flows to the booster air pipe 7 and enters the booster space 39, pushing the air piston 13 and the cylinder piston rod 14 to move towards the hydraulic cylinder 11. After the piston rod passes the oil sealing ring 22, a sealed high-pressure space is formed in the hydraulic cylinder, compressing the hydraulic oil and pressing it into the oil storage space 36, thereby pushing the booster piston 16 to generate a strong pulling force and completing one working cycle.

[0037] Reference Figure 1 , Figures 4 to 5 The air circuit mechanism 3 includes air circuit 1 31, which provides a channel for the transmission of air pressure in the booster air pipe 7, ensuring the directionality and stability of the booster gas delivery. Air circuit 1 31 is located inside the booster air pipe 7, enabling it to directly cooperate with the gas flow function of the booster air pipe 7, ensuring that the high-pressure gas can smoothly pass through air circuit 1 31 into the subsequent space. The pressure reducing air pipe 6 is equipped with air circuit 2 32, which is a channel for guiding compressed air in the pressure reducing air pipe 6, realizing the delivery of pressure reducing gas from the knob air source switch valve 26 to the pressure reducing space. The air head 1 is equipped with air circuit 3 33, which is designed to have a much larger orifice than the passage leading to the booster air pipe 7. Therefore, most of the gas can first flow into the air pressure space 34 through air circuit 3 33, giving priority to starting the oil pre-charge process. The small oil tank 4 is equipped with oil circuit 35, which serves as a channel for the flow of hydraulic oil in the small oil tank 4. With the push of the oil-gas separation piston 8, the hydraulic oil is smoothly pushed out to the subsequent oil passage.

[0038] The hydraulic cylinder body 11 has an internal oil storage space 36, which is used to hold hydraulic oil supplied from the oil circuit 35. Under the injection of high-pressure oil, it can push the booster piston 16 to move and generate pulling force. The hydraulic cylinder body 11 also has an internal pressure relief space 37, which, together with the pressure relief space 38, receives gas from the pressure relief pipe 6. The gas pressure pushes the booster piston 16 to its initial position and holds it there. The pneumatic cylinder body 12 has an internal pressure relief space 38, which works in conjunction with the pressure relief space 37. The function is to use air pressure to keep the air piston 13 in the initial position, ensuring that the cylinder is in a ready state before operation. The rear end of the pneumatic cylinder 12 is provided with a pressurization space 39. When the air pressure flows to the pressurization pipe 7, it will enter this space, generating a strong air pressure to push the air piston 13 and the cylinder piston rod 14 to move rapidly towards the hydraulic cylinder 11. The small oil tank 4 is provided with a pneumatic space 34. Under the action of the gas delivered by the air passage 33, pressure is formed, which in turn pushes the oil-gas separation piston 8 to push out the hydraulic oil in the small oil tank 4, starting the oil pre-charging stage.

[0039] Specifically, air path 1 31 is located inside the booster air pipe 7, providing a channel for the transmission of booster gas, ensuring the directionality and stability of the delivery, and ensuring that the high-pressure gas smoothly enters the subsequent space. Air path 2 32 is located inside the depressurizing air pipe 6, responsible for guiding compressed air and realizing the delivery of depressurized gas from the knob air source switch valve 26 to the depressurization space. Air path 33 is located inside the connecting air head 1. Because its orifice is much larger than the passage leading to the booster air pipe 7, most of the gas can first flow into the air pressure space 34 through it, giving priority to starting the oil pre-charge process. Oil path 35 is inside the small oil storage tank 4, serving as a hydraulic oil flow channel, cooperating with the oil-gas separation. The piston 8 pushes the hydraulic oil smoothly out to the subsequent oil passage. At the same time, the hydraulic cylinder 11 has an oil storage space 36 and a pressure reducing space 37. The oil storage space 36 contains the hydraulic oil delivered from the oil circuit 35. After the high-pressure oil is injected, it can push the booster piston 16 to move and generate a pulling force. The pressure reducing space 37 and the pressure reducing space 38 together receive the gas from the pressure reducing air pipe 6. The pressure reducing space 38 is located inside the pneumatic cylinder 12 and works in conjunction with the pressure reducing space 37 to use the pressure reducing air to keep the pneumatic piston 13 in the initial position, ensuring that the cylinder is ready before operation.

[0040] The implementation principle of this application embodiment is as follows: When the operator uses the reverse air-hydraulic booster cylinder, compressed air enters from the air source connector 28, first passing through the regulating valve 25. The operator can set the required air pressure through the adjusting knob 27. The pressure will ultimately determine the pulling force after boosting. At this time, the gas first passes through the normally open passage of the knob air source switch valve 26, and then enters the first pressure reducing space 37 and the second pressure reducing space 38 through the pressure reducing air pipe 6. At this time, the air pressure pushes the air piston 13 and the boosting piston 16 to and holds them in the initial position. At this time, no pulling force is generated. When the knob air source switch valve 26 is activated, the knob air source switch valve 26 will immediately cut off the air to the pressure reducing air pipe 6, and at the same time guide the air pressure to the third air passage 33 and the small oil tank 4, as well as the boosting air pipe 7. Since the orifice design of the third air passage 33 is much larger than the passage to the boosting air pipe 7, most of the gas first rushes into the air pressure space 34, which in turn pushes the oil-gas separation piston 8, causing the hydraulic oil in the small oil tank 4 to flow along the oil pressure space 34. The hydraulic passage is pressurized, allowing it to flow through the side hole into the oil storage space 36. This begins to push the booster piston 16 slightly towards the pneumatic cylinder 12. When the pre-filling stage of the hydraulic passage is completed, i.e., when the oil-gas separation piston 8 can no longer be pushed, all the air pressure is concentrated and flows into the booster air pipe 7 and into the booster space 39. At this time, a strong air pressure is generated, pushing the air piston 13 and the cylinder piston rod 14 rapidly towards the hydraulic cylinder 11. After the cylinder piston rod 14 passes the oil seal ring 22, it forms a sealed high-pressure space with the oil seal ring 22 in the hydraulic cylinder 11, rapidly compressing the hydraulic oil in the chamber. This high-pressure oil is forcibly forced into the oil storage space 36, thereby using a huge force to push the booster piston 16 towards the pneumatic cylinder 12, generating a strong pulling force and completing one working cycle. When the knob air source switch valve 26 is reset, the booster air passage is cut off, and the pressure reducing air pipe 6 is reconnected, causing the air piston 13 and the booster piston 16 to return to their original positions in preparation for the next operation.

[0041] The connecting screw 19 is used to connect the screw 29 by cooperating with the fastening nut 18. The oil plug screw 20 is used to plug the oil hole on the cylinder to prevent oil leakage. The wear-resistant copper ring 17 can prevent the booster piston 16 from having direct hard contact and friction.
