Description

Technical Field

[0001] The invention relates to the technical field of inflatable equipment, and in particular to an inflatable device for a monotube inflatable shock absorber. Background Art

[0002] The monotube gas-filled shock absorber is a new type of vibration reduction equipment, which is widely used in automobile suspension systems. Its unique structure and working principle give it significant advantages in shock absorption effect and stability. The monotube gas-filled shock absorber adopts a floating piston design, which divides the working chamber into three parts. This design helps to effectively isolate the oil and gas and improve the shock absorption effect. High-pressure nitrogen is filled in the chamber formed by the floating piston and one end of the cylinder. The presence of this high-pressure nitrogen can use the expansion and compression of nitrogen to compensate for the change in cylinder volume caused by the piston rod entering and exiting. The floating piston is equipped with a large-section O-ring to completely separate the oil and gas to form a gas-sealed piston. This design ensures that the oil and gas will not mix with each other, improving the working performance of the shock absorber.

[0003] The patent document with the announcement number CN202647183U discloses a cylinder-type automobile shock absorber inflation device, comprising an operating table, a clamping cylinder provided on the operating table, an electrical control device, and a closed cylinder fixedly connected to the operating table;

[0004] When inflating a monotube pneumatic shock absorber, if the fixing effect is not good or the inflation speed is too fast or too slow, it may have an adverse effect on the performance of the shock absorber. When the fixing effect of the shock absorber is not good, it may cause the sealing components (such as O-rings) to fail to be installed correctly or be subjected to uneven pressure, thereby affecting its sealing performance. This poor sealing will cause gas leakage, which in turn affects the damping characteristics and overall performance of the shock absorber; and too fast an inflation speed may cause a sharp change in the internal temperature of the shock absorber, thereby affecting the fluidity and viscosity of the oil. Too fast an inflation speed may cause excessive pressure shock to the seals (such as elastic sealing sleeves), increasing the risk of damage. Once the seals are damaged, it will cause gas leakage and oil contamination, seriously affecting the performance and service life of the shock absorber. The above-mentioned design and the current conventional inflation equipment are relatively negligent in monitoring the inflation speed, which makes it difficult to respond and deal with any unexpected situation during the inflation process. Therefore, we propose an inflation device for a monotube pneumatic shock absorber to solve this problem. Summary of the invention

[0025] The beneficial effects of the present invention are:

[0026] 1. In the present invention, the inflating device for a mono-tube pneumatic shock absorber is configured by placing the mono-tube pneumatic shock absorber to be inflated on the top of the inflating platform and making it located between four clamping plates, and then starting the first electric push rod to drive the turntable to rotate. The turntable drives the multiple square plates to approach each other through the cooperation of multiple guide holes and corresponding round rods, and the multiple square plates drive the multiple clamping plates to approach each other, thereby clamping and fixing the mono-tube pneumatic shock absorber. Then, the lifting plate, the connecting column, the pressing plate and the pressing ring are driven downward by starting the second cylinder, so that the top of the mono-tube pneumatic shock absorber is pressed and fixed by the pressing ring, thereby ensuring the stability of the pressing and fixing.

[0027] 2. In the present invention, the inflating device for a monotube pneumatic shock absorber drives the inflating head to move downward by starting the first cylinder, so that the inflating head is inserted into the inflating hole of the monotube pneumatic shock absorber, and then the inflating pump is started, so that nitrogen is introduced into the inflating head through the inflating pipe, and then introduced into the interior of the monotube pneumatic shock absorber through the inflating head, so as to achieve inflation, and the inflation pressure is monitored by a pressure gauge. When the pressure value reaches the specified requirement, the controller controls the second electric push rod to drive the sealing plate and the sealing ring to move upward, so that the sealing ring abuts against the interior of the round shell to achieve sealing, and controls the inflating pump to stop working, so as to complete the inflation work;

[0028] 3. In the present invention, the inflation device for a single-tube pneumatic shock absorber monitors the flow rate of the gas flowing through the inflation head through a monitoring mechanism. Specifically, when the gas flows through the inflation head, the wind drives the fan blades to rotate, and the fan blades drive the active bevel gear to rotate through the rotating shaft. The active bevel gear drives the two horizontal axes and the two rotating frames to rotate through the engagement with the driven bevel gear. The rotating frame drives the sliding plate to perform a circular motion, and the sliding plate is thrown outward under the action of centrifugal force. The sliding seat drives the rotating column and the moving disk to move to the side away from the rotating frame through the cooperation with the inclined rod, thereby compressing the compression spring, and the pressure change is monitored by the pressure sensor, and the pressure change result is recorded. The signal is transmitted to the controller, and the controller analyzes the change of the pressure value. When the pressure value becomes smaller, the controller controls the air pump to increase the output pressure. When the pressure value becomes larger, the controller controls the output pressure of the air pump to decrease, thereby maintaining a stable inflation speed and ensuring inflation safety. It can also avoid damage to the shock absorber while ensuring inflation efficiency. When the pressure value changes frequently and violently, the controller controls the second electric push rod to drive the sealing plate and the sealing ring to move upward to achieve sealing of the round shell, thereby blocking the gas circulation, and controlling the air pump to stop moving, and facilitating the detection of the sealing structure of the shock absorber to eliminate the influence of leakage on inflation.

[0029] 4. In the present invention, the inflating device for a monotube pneumatic shock absorber, when the inflation speed increases instantaneously due to equipment failure, the speed of the circular motion of the sliding seat increases instantaneously, so that it is quickly thrown outward, and drives the moving plate to move outward rapidly, and pushes the two trapezoidal clamping plates away from each other through the contact with the positioning plate, so that the trapezoidal clamping plates are separated from the clamping grooves, and the fixing of the connecting plate is released. Since the initial state of the compression spring is a compressed state, the annular plate moves upward rapidly under the elastic force of the compression spring, and the inflation hole is closed, thereby instantly cutting off the gas filling to avoid accidents;

[0030] 5. In the present invention, the inflation device for a monotube pneumatic shock absorber can achieve stable clamping of the monotube pneumatic shock absorber through the setting of the fixing mechanism and the clamping mechanism, and realize automatic inflation in cooperation with the inflation mechanism. At the same time, with the cooperation of the monitoring mechanism, the inflation speed can be monitored and adjusted in real time, and it can play an emergency protection role in the event of an accident, thereby avoiding accidents and ensuring the safety of inflation.

[0061] In this embodiment, when in use, the monotube inflatable shock absorber to be inflated is placed on the top of the inflatable platform 1 and located between the four clamping plates 601, and then the first electric push rod 611 is started to drive the turntable 605 to rotate. The turntable 605 drives the multiple square plates 602 to approach each other through the cooperation of the multiple guide holes 606 and the corresponding round rods 604, and the multiple square plates 602 drive the multiple clamping plates 601 to approach each other, so as to achieve the clamping and fixing of the monotube inflatable shock absorber. When the pressure value monitored by the first pressure sensor 610 reaches the preset value, the first electric push rod 611 is controlled to stop running through the controller 22, and then the lifting plate 303, the connecting column 304, the pressing plate 305 and the pressing ring 306 are driven by starting the second cylinder 302. It moves downward, thereby pressing and fixing the top of the monotube pneumatic shock absorber through the pressure ring 306, thereby ensuring the stability of the pressing and fixing, and driving the inflation head 203 to move downward by starting the first cylinder 202, so that the inflation head 203 is inserted into the inflation hole 204 of the monotube pneumatic shock absorber, and then starting the inflation pump 4, so that nitrogen is introduced into the inflation head 203 through the inflation pipe 401, and then introduced into the interior of the monotube pneumatic shock absorber through the inflation head 203, so as to achieve inflation, and monitor the inflation pressure through the pressure gauge 403. When the pressure value reaches the specified requirement, the controller 22 controls the second electric push rod 8 to drive the sealing plate 802 and the sealing ring to move upward, so that the sealing ring abuts against the inside of the round shell 7 to achieve closure, and controls the inflation pump 4 to stop working. , thereby completing the inflation work, the flow rate of the gas flowing through the inflation head 203 is monitored by the monitoring mechanism. Specifically, when the gas flows through the inflation head 203, the wind drives the fan blades 10 to rotate, and the fan blades 10 drive the active bevel gear 11 to rotate through the rotating shaft 13. The active bevel gear 11 drives the two horizontal shafts 9 and the two rotating frames 901 to rotate through the engagement with the driven bevel gear 12. The rotating frame 901 drives the sliding plate 902 to perform a circular motion, and the sliding plate 902 is thrown outward under the action of centrifugal force. The sliding seat drives the rotating column 904 and the moving disk 905 to move to the side away from the rotating frame 901 through the cooperation with the inclined rod 903, thereby compressing the compression spring 906, and the pressure change is monitored by the pressure sensor, and The signal of the pressure change result is transmitted to the controller 22, and the controller 22 analyzes the change of the pressure value. When the pressure value becomes smaller, the controller 22 controls the air pump 4 to increase the output pressure. When the pressure value becomes larger, the controller 22 controls the output pressure of the air pump 4 to decrease, thereby maintaining a stable inflation speed, ensuring inflation safety, and avoiding damage to the shock absorber while ensuring inflation efficiency. When the pressure value changes frequently and violently, the controller 22 controls the second electric push rod 8 to drive the sealing plate 802 and the sealing ring to move upward to achieve sealing of the round shell 7, thereby blocking the gas circulation, and controlling the air pump 4 to stop moving, and facilitating the detection of the sealing structure of the shock absorber to eliminate the influence of leakage on inflation;

[0062] When the inflation speed increases instantaneously due to equipment failure, the speed of the circular motion of the sliding seat increases instantaneously, causing it to be quickly thrown outward, and driving the movable disk 905 to move outward rapidly, and pushing the two trapezoidal clamping plates 18 away from each other through the abutment with the positioning plate 19, so that the trapezoidal clamping plates 18 are disengaged from the clamping slots, releasing the fixation of the connecting plate 16. Since the initial state of the compression spring 17 is a compressed state, the annular plate 15 moves upward rapidly under the elastic force of the compression spring 17, and closes the inflation hole 204, thereby instantly cutting off the gas filling to avoid accidents. After troubleshooting, the sealing plate 802 and the L rod 803 can be driven downward by the second electric push rod 8, and the connecting plate 16 and the annular plate 15 are pushed downward by the abutment of the L rod 803 with the reset protrusion, thereby realizing the reset of the annular plate 15.
