Description

Technical Field

[0001] The utility model belongs to the technical field of oil pressure buffers, and in particular relates to an oil pressure buffer with adjustable damping force. Background Art

[0002] Hydraulic shock absorbers can reduce vibration and noise in automated machinery operations, convert the kinetic energy generated by moving objects into heat and release it into the atmosphere, effectively stopping objects in a balanced manner during motion. These shock absorbers improve machinery efficiency and production capacity, extend machine life and reduce maintenance costs, stabilize mechanical operation and maintain product quality, making machine operation safer and preventing accidents, improving personnel efficiency, and increasing a company's competitive advantage.

[0003] Hydraulic shock absorbers are equipped with an oil drain hole, piston, piston rod, and impact head. Existing hydraulic shock absorbers lack damping and cannot adjust the damping force to suit different working scenarios, which limits their flexibility and applicability in different working scenarios. Because the damping force cannot be adjusted according to actual needs, hydraulic shock absorbers may provide excessive damping in some cases, causing excessive deceleration or stopping of moving parts, affecting the operating efficiency and performance of the equipment. In other cases, insufficient damping may fail to effectively mitigate impact or vibration, thereby increasing equipment wear, noise, and safety hazards. These limitations and deficiencies not only restrict the application scope of hydraulic shock absorbers but may also adversely affect the stability and reliability of the equipment. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above problems and provide a damping force adjustable oil pressure buffer, which can adjust the size of its own oil discharge hole and the flow rate of the hydraulic oil to achieve changes in the damping force.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides a damping force adjustable oil pressure buffer, comprising a main body, an oil storage chamber is provided inside the main body, an oil drain pipe is connected to the oil storage chamber, an oil drain hole is provided at one end of the oil drain pipe, and an adjustment mechanism is provided on the outside of the oil drain hole;

[0007] The adjustment mechanism includes a gear ring, a sealing baffle, a connecting rod, a turntable and a gear. The gear ring is rotatably connected to one end of the oil drain pipe. The outside of the gear ring is rotatably connected to several connecting rods. The sealing baffle is located at one end of the oil drain pipe and is rotatably connected to one end of the connecting rod. The turntable is rotatably arranged on the outside of the main body. The turntable is rotatably connected to the gear, and the gear is meshed with the gear ring.

[0008] A further improvement of the present invention is that a return spring is provided inside the main body, and a piston is provided above the return spring.

[0009] A further improvement of the present invention is that the other end of the piston is fixedly connected to a piston rod, and the other end of the piston rod extends out of the main body and is fixedly provided with an impact head.

[0010] A further improvement of the present invention is that a rotating shaft is fixedly provided at one end of the rotating disk.

[0011] A further improvement of the present invention is that one end of the rotating shaft passes through the oil storage chamber and the oil drain pipe and is fixed with a gear.

[0012] A further improvement of the present invention is that a sealing plug is provided on the top of the main body, and a sealing ring is provided on the top of the inner cavity of the main body.

[0013] A further improvement of the present invention is that an air bag is provided at the connection between the sealing plug and the sealing ring.

[0014] A further improvement of the present invention is that a sponge is provided on one side of the airbag.

[0015] A further improvement of the present invention is that an air intake pipe is provided below the sealing ring, and the top end of the air intake pipe is connected to the airbag.

[0016] A further improvement of the present invention is that a plurality of sealing baffles and connecting rods are provided.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The utility model provides an oil pressure buffer with adjustable damping force, which provides an oil storage chamber inside the oil pressure buffer body, the oil storage chamber is connected to an oil drain pipe, an oil drain hole is provided at one end of the oil drain pipe, and an adjustment mechanism is provided on the outside of the oil drain hole. The turntable, gear, gear ring and connecting rod in the adjustment mechanism cooperate with each other, and the user can conveniently adjust the opening of the oil drain hole. When the turntable is rotated, the gear drives the gear ring to rotate, and the gear ring drives the sealing baffle to move through the connecting rod, thereby changing the effective opening size of the oil drain hole. This design allows the user to adjust the speed and amount of the oil flow according to needs, and then adjust the damping force generated by the buffer, thereby enhancing the adaptability and flexibility of the equipment.

The airbag is inflated and moves with the sponge. Since the sponge fits the outside of the piston rod, even if hydraulic oil splashes out, it can be absorbed by the sponge, further preventing the hydraulic oil from being brought out. Under the triple action of the sealing plug, sealing ring and sponge, the hydraulic oil is prevented from splashing to the greatest extent, thereby achieving the sealing effect.

[0034] The present invention is described in further detail below with reference to the accompanying drawings:

[0035] like Figure 1 As shown, an embodiment of the utility model provides an oil pressure buffer with adjustable damping force, including a main body 1, a return spring 2, a piston 3, a piston rod 4, an impact head 5 and an oil storage chamber 6, wherein: a return spring 2 is arranged inside the main body 1, a piston 3 is arranged above the return spring 2, and the other end of the piston 3 is fixedly connected to the piston rod 4. The setting of the return spring 2 can provide an initial buffering effect when the piston rod 4 is subjected to external force, thereby reducing the impact force; when the external force continues to act, the movement of the piston 3 in the oil will produce a damping effect, further absorbing and dispersing the impact force, thereby achieving efficient buffering; the other end of the piston rod 4 extends out of the main body 1 and is fixedly provided with an impact head 5, so that the oil pressure buffer can stably withstand external force and is not easily deformed or damaged.

[0036] like Figure 2 、 Figure 3 and Figure 4 As shown, an oil storage chamber 6 is provided inside the main body 1, the oil storage chamber 6 is connected to an oil drain pipe 7, an end of the oil drain pipe 7 is provided with an oil drain hole 8, and an adjustment mechanism is provided on the outside of the oil drain hole 8;

[0037] The adjusting mechanism includes a gear ring 10, a sealing baffle 11, a connecting rod 12, a turntable 14 and a gear 16. The gear ring 10 is rotatably connected to one end of the oil drain pipe 7. The outside of the gear ring 10 is rotatably connected to several connecting rods 12. The sealing baffle 11 is located at one end of the oil drain pipe 7 and is rotatably connected to one end of the connecting rod 12. The turntable 14 is rotatably arranged on the outside of the main body 1. The turntable 14 is rotatably connected to the gear 16, and the gear 16 is meshed with the gear ring 10. The rotation of the turntable 14 can drive the meshing of the gear 16 and the gear ring 10, thereby driving the movement of the connecting rod 12 and the sealing baffle 11, allowing the user to adjust the degree of blocking of the sealing baffle 11 on the oil drain hole 8 as needed, thereby controlling the discharge speed and buffering effect of the hydraulic oil. In addition, the close connection between the sealing baffle 11 and the oil drain pipe 7 ensures the sealing and stability of the oil pressure buffer under high pressure and high speed impact. This adjustability enables the oil pressure buffer to adapt to different working environments and impact forces, providing a more precise buffering effect.

[0038] Preferably, in this embodiment, five sealing baffles 11 and five connecting rods 12 are provided.

[0039] like Figure 5As shown, a sealing plug 17 is provided on the top of the main body 1, and a sealing ring 18 is provided on the top of the inner cavity of the main body 1. An air bag 19 is provided at the connection between the sealing plug 17 and the sealing ring 18. A sponge 21 is provided on one side of the air bag 19, and an air inlet pipe 22 is provided below the sealing ring 18. The top of the air inlet pipe 22 is connected to the air bag 19. The provided sealing plug 17 and sealing ring 18 can prevent the hydraulic oil from being brought out from the connection between the piston rod 4 and the main body 1 when the piston 3 rises. At the same time, when the piston 3 rises, the gas inside the main body 1 is compressed, and then the compressed air enters the interior of the air bag 19 from the air inlet pipe 22. The air bag 19 is inflated and moves with the sponge 21. Since the sponge 21 fits the outside of the piston rod 4, even if hydraulic oil splashes out, it can be sucked into the sponge 21, further preventing the hydraulic oil from being brought out. Under the triple action of the sealing plug 17, the sealing ring 18 and the sponge 21, the hydraulic oil is prevented from splashing to the greatest extent, thereby achieving the sealing effect.

[0040] Preferably, in this embodiment, two sponges 21 are provided, and are respectively located on the outside of the piston rod 4 .

[0041] like Figure 6 As shown, a rotating shaft 15 is fixedly provided at one end of the rotating disk 14, and one end of the rotating shaft 15 passes through the oil storage chamber 6 and the oil drain pipe 7 and is fixed with a gear 16.

[0042] How it works

[0043] The regulating mechanism can adjust the size of the oil drain hole 8, thereby adjusting the flow rate of the hydraulic oil discharged, and realizing the change of the damping force of the oil pressure buffer. The larger the opening of the oil drain hole 8, the easier it is for the hydraulic oil inside the oil pressure buffer to flow out through the oil drain hole 8, and the smaller the buffering damping force generated by the hydraulic oil. On the contrary, the smaller the opening of the oil drain hole 8, the more difficult it is for the hydraulic oil to pass through, and the damping force of the oil pressure buffer will become larger accordingly. The flow rate of the hydraulic oil is adjusted according to the actual working conditions, and the performance of the product is adjusted to the best, which is convenient for cooperating with different working environments. The method of adjusting the flow rate of the hydraulic oil is as follows: Hydraulic oil is stored in the oil storage chamber 6, and the turntable 14 drives the connecting shaft 15 to rotate. When the connecting shaft 15 rotates, it drives the gear 16 to rotate. When the gear 16 rotates, it drives the gear ring 10 to rotate. The rotation of the gear ring 10 drives the connecting rod 12 to rotate. The rotation of the connecting rod 12 drives the five sealing baffles 11 to rotate synchronously. The rotation of the baffle 11 opens the oil drain hole 8. By controlling the rotation angle of the turntable 14, the rotation angle of the five sealing baffles 11 can be controlled, and then the opening amplitude of the oil drain hole 8 can be controlled, which is conducive to adjusting the oil drain hole 8 and thus adjusting the flow rate of the discharged hydraulic oil. The provided sealing ring 18 and sealing plug 17 can prevent the hydraulic oil from being brought out from the connection between the piston rod 4 and the main body 1 when the piston 3 rises. At the same time, when the piston 3 rises, the gas inside the main body 1 is compressed, and then the compressed gas enters the interior of the airbag 19 from the air inlet pipe 22. After that, the airbag 19 is inflated and moves with the sponge 21. The two sponges 21 fit the outside of the piston rod 4. Even if hydraulic oil splashes out, it can be sucked into the sponge 21, further preventing the hydraulic oil from being brought out. Under the triple action of the sealing plug 17, the sealing ring 18 and the sponge 21, the hydraulic oil is prevented from splashing to the greatest extent and a sealing effect is achieved.
