Description

Technical Field

[0001] The invention relates to the field of hydraulic cylinders, and more particularly to a nonlinear variable damping deceleration hydraulic cylinder. Background Art

[0002] The damping hydraulic cylinder, also known as the hydraulic damping cylinder or hydraulic damper, is a common hydraulic component. The damping hydraulic cylinder consists of an oil cylinder and a piston, and the oil cylinder is filled with oil. When the piston moves under force, the oil flows through the damping hole, thereby producing a damping effect and slowing down the movement speed. This principle mainly depends on the viscosity and flow resistance of the oil.

[0003] The nonlinear variable damping deceleration hydraulic cylinder combines the nonlinear damping characteristics with the deceleration function of the hydraulic cylinder, and can achieve stable and controllable movement under a variety of complex working conditions. The hydraulic cylinder uses an internally designed nonlinear damping mechanism to make the damping force change nonlinearly with the change of the piston movement speed. When the piston moves quickly, the damping force increases, thereby slowing down the movement speed of the piston; when the piston moves slowly, the damping force decreases, allowing the piston to move more smoothly.

[0004] The traditional nonlinear variable damping deceleration hydraulic cylinder will quickly consume the hydraulic oil inside due to high-frequency reciprocating movement during use, requiring workers to frequently replenish the hydraulic oil. Failure to replenish the oil in time will cause the device to fail or even be damaged.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 8 A nonlinear variable damping deceleration hydraulic cylinder comprises a base component 1, a hydraulic component 2 is fixedly mounted on one end of the upper surface of the base component 1, an oil storage tank component 3 is detachably mounted on the end of the upper surface of the base component 1 away from the hydraulic component 2, the hydraulic component 2 comprises a hydraulic cylinder wall 21, a piston rod 22 is slidably mounted in the middle position inside the hydraulic cylinder wall 21, a piston head 23 is fixedly mounted on the bottom end of the piston rod 22, a plurality of evenly distributed rubber sealing rings 232 are sleeved on the piston head 23, a conical head 231 is provided at the bottom end of the piston head 23, the top end of the piston rod 22 extends to the outside of the hydraulic cylinder wall 21, a connecting pipe 25 is fixedly mounted on one side of the outer surface of the hydraulic cylinder wall 21, the top end of the connecting pipe 25 is connected to the inner top end of the hydraulic cylinder wall 21, the bottom end of the connecting pipe 25 is fixedly mounted on the base component 1, and a compression spring 24 is fixedly connected between the piston head 23 and the inner top end of the hydraulic cylinder wall 21.

[0037] In actual use, one end of the piston rod 22 and the base component 1 are respectively installed on two parts. At this time, when the part moves, the hydraulic component 2 can absorb the kinetic energy generated by the part, and the faster the moving speed of the part, the greater the resistance generated by the hydraulic component 2, and the slower the moving speed of the part, the smaller the resistance generated by the hydraulic component 2. When the piston rod 22 is subjected to the thrust or tension from the part, the piston rod 22 will drive the piston head 23 to move. In the initial state, the hydraulic cylinder wall 21 and the oil storage tank component 3 are both filled with hydraulic oil. The piston head 23 divides the interior of the hydraulic cylinder wall 21 into two upper and lower chambers. When the piston rod 22 is pulled At this time, the piston head 23 rises, and the hydraulic oil in the upper chamber will be squeezed into the oil storage tank component 3, while the lower chamber will generate negative pressure and then absorb hydraulic oil from the oil storage tank component 3, so that the internal pressure of the hydraulic cylinder wall 21 remains balanced. When the hydraulic oil circulates through the oil storage tank component 3, it can automatically replenish the hydraulic oil lost in the hydraulic cylinder wall 21, preventing the hydraulic oil from being lost due to long-term use and causing insufficient hydraulic oil, thereby increasing the friction between the piston head 23 and the hydraulic cylinder wall 21, thereby reducing the performance and service life of the device, and can automatically replenish the hydraulic oil with each reciprocating movement, without the need for workers to frequently replenish it.

[0038] The hydraulic component 2 is used to absorb the kinetic energy of the impact. The hydraulic component 2 is used to supplement the hydraulic oil to the base component 1. The oil storage tank component 3 includes an oil storage tank shell 31. A partition 32 is fixedly installed inside the oil storage tank shell 31. The partition 32 divides the interior of the oil storage tank shell 31 into a first chamber 311 and a second chamber 312. A first liquid outlet pipe 36 is fixedly installed inside the first chamber 311, and a second liquid outlet pipe 37 is fixedly installed inside the second chamber 312. The top of the oil storage tank shell 31 is detachably installed with an oil storage tank cover 33. The upper ends of the first liquid outlet pipe 36 and the second liquid outlet pipe 37 both extend into the interior of the oil storage tank cover 33. Two mounting grooves 11 corresponding to the first liquid outlet pipe 36 and the second liquid outlet pipe 37 are opened on the base component 1. A first pipe 12 and a second pipe 13 are opened inside the base component 1. The first pipe 12 is used to connect the hydraulic cylinder wall 21 and one of the mounting grooves 11, and the second pipe 13 is used to connect the connecting pipe 25 with the other mounting groove 11.

[0039] When the piston rod 22 is pushed, the piston rod 22 will push the piston head 23 down, and the hydraulic oil in the lower chamber will be squeezed into the first outlet pipe 36 through the first pipe 12. At the same time, the lower chamber will absorb the hydraulic oil from the second outlet pipe 37 through the connecting pipe 25 and the second pipe 13. When the piston rod 22 is pulled up, the upper chamber will push the hydraulic oil into the second outlet pipe 37 through the connecting pipe 25 and the second pipe 13, and the lower chamber will absorb the hydraulic oil from the first outlet pipe 36 through the first pipe 12. Regardless of whether the device is pulled or pushed, one of the first outlet pipe 36 and the second outlet pipe 37 will produce One of them has an absorption effect, while the other has a pushing effect, thereby realizing the circulation of the hydraulic oil. When the hydraulic oil inside the hydraulic cylinder wall 21 is consumed, bubbles will be generated inside the hydraulic cylinder wall 21. At this time, as the piston rod 22 moves back and forth, the bubbles can also be pushed into the oil storage tank component 3. Because the density of the bubbles is much smaller than the density of the hydraulic oil, the bubbles will stay at the upper end of the oil storage tank shell 31 and be retained in the oil storage tank component 3. Because the bubbles are retained in the oil storage tank component 3, the device will push the same volume of hydraulic oil into the interior of the hydraulic cylinder wall 21 in order to maintain a balanced state, thereby realizing automatic replenishment of the hydraulic oil.

[0040] The first liquid outlet pipe 36 and the second liquid outlet pipe 37 both include an upper liquid outlet pipe 361, a cover plate 362 is provided at the top of the upper liquid outlet pipe 361, an inner pipe 363 is fixedly installed on the lower surface of the cover plate 362, the first liquid outlet pipe 36 is slidably clamped at the inner top of the upper liquid outlet pipe 361, a plurality of evenly distributed first grooves 364 are provided at the top of the upper liquid outlet pipe 361, a plurality of second grooves 365 corresponding to the first grooves 364 are provided at the lower end of the inner pipe 363, and the length of the second grooves 365 is less than that of the first grooves 364. Because the two grooves have different lengths, the amount of liquid passing through the two grooves will change when the overlap between the two grooves is different, which is convenient for implementation. The nonlinear damping change is shown. The lower surface of the oil storage tank shell 31 is fixedly installed with a first plug interface 34 and a second plug interface 35 corresponding to the two mounting grooves 11. The first plug interface 34 is connected to the first liquid outlet pipe 36, and the second plug interface 35 is connected to the second liquid outlet pipe 37. The bottom end of the upper liquid outlet pipe 361 is fixedly installed with a lower liquid outlet pipe 367, and a fan-shaped groove 366 is formed between the lower liquid outlet pipe 367 and the upper liquid outlet pipe 361. An annular rubber sheet 368 is fixedly installed at the inner bottom end of the upper liquid outlet pipe 361, and an annular bevel block 369 is fixedly installed at the inner top of the lower liquid outlet pipe 367. The annular rubber sheet 368 fits with the inner surface of the annular bevel block 369.

[0041] When there is hydraulic oil pushing inside the first liquid outlet pipe 36 or the second liquid outlet pipe 37, the cover plate 362 is lifted up because of the increase in internal pressure of the upper liquid outlet pipe 361. If the piston rod 22 is pushed or pulled at a faster speed, the liquid will quickly flow into the upper liquid outlet pipe 361, and then the cover plate 362 will be quickly pushed to the maximum position. When the cover plate 362 and the inner pipe 363 are pushed, the second groove body 365 will gradually overlap with the first groove body 364. When there is no driving force, the second groove body 365 is completely staggered with the first groove body 364, that is, the top of the upper liquid outlet pipe 361 is closed. When the cover plate 362 is pushed to the maximum position, the overlap between the first groove body 364 and the second groove body 365 will decrease. When the moving speed of the parts is too fast, the cover plate 362 will be quickly pushed to the maximum position, and at this time the second groove body 365 and the first groove body 364 When the overlap is reduced, the liquid flow rate inside the upper liquid outlet pipe 361 will be reduced. When the flow rate is reduced, a larger resistance will be generated, which is used to quickly reduce the moving speed of the piston rod 22. When the piston rod 22 is slowly pushed or pulled, the cover plate 362 is slowly pushed, and the second groove body 365 will completely overlap with the first groove body 364, and the liquid flow rate reaches the maximum. At this time, the resistance generated is relatively minimal, and thus different moving speeds can be adapted. Because the cover plate 362 is located at the top of the upper liquid outlet pipe 361, the hydraulic oil will be pushed into the upper end of the oil storage tank component 3. By arranging the cover plate 362 and the inner pipe 363, the resistance can be changed according to the flow speed of the liquid, thereby realizing a nonlinear change in the resistance of the device. The resistance generated by the liquid can better protect the compression spring 24, reduce the workload of the compression spring 24, and thus make the device run more stably and have a longer service life.

[0042] When the first liquid outlet pipe 36 or the second liquid outlet pipe 37 generates a suction effect, the cover plate 362 will block the upper end of the upper liquid outlet pipe 361 under the action of suction, and the hydraulic oil will push the annular rubber sheet 368 to deform under the action of suction, and then the hydraulic oil will enter the interior of the upper liquid outlet pipe 361 through the fan-shaped groove 366. When the interior of the first liquid outlet pipe 36 or the second liquid outlet pipe 37 generates a pushing effect, the annular rubber sheet 368 will be pushed against the annular bevel block 369, and then the fan-shaped groove 366 is in a closed state at this time. The fan-shaped groove 366 is located at the inner bottom end of the oil storage tank shell 31, so the suction effect will be from the oil storage tank. The inner bottom end of the shell 31 is carried out, and one of the first liquid outlet pipe 36 and the second liquid outlet pipe 37 will produce a suction effect and the other will produce a pushing effect, so the used hydraulic oil will be pushed from the inside of the hydraulic cylinder wall 21 into the inner top of the oil storage tank shell 31, and the new hydraulic oil will pass through the first liquid outlet pipe 36 or the second liquid outlet pipe 37 from the inner bottom end of the oil storage tank shell 31 into the inside of the hydraulic cylinder wall 21, which can automatically realize the circulation of the hydraulic oil, prevent the performance of the hydraulic oil from being reduced due to long-term use, or prevent the hydraulic oil from precipitating solid precipitation due to repeated squeezing, thereby increasing the service life of the hydraulic oil and increasing the practicality of the device.

[0043] A first filter plate 331 is detachably mounted on the inner lower end of the oil storage tank cover 33, and a second filter plate 332 is slidably mounted on the inner side of the oil storage tank cover 33. The first filter plate 331 has two through grooves 336 corresponding to the first liquid outlet pipe 36 and the second liquid outlet pipe 37. Two supporting shells 337 are fixedly mounted on the upper surface of the second filter plate 332 at positions corresponding to the through grooves 336. The top ends of the first liquid outlet pipe 36 and the second liquid outlet pipe 37 extend into the interior of the supporting shell 337. A plurality of evenly distributed return springs 335 are connected between the second filter plate 332 and the inner wall of the oil storage tank cover 33.

[0044] When the hydraulic oil is pushed out from the upper outlet pipe 361, the cover plate 362 is pushed, so the cover plate 362 will drive the support shell 337 to move upward, and the support shell 337 will drive the second filter plate 332 to move upward. At this time, a chamber will be formed between the second filter plate 332 and the first filter plate 331, and the hydraulic oil will be pushed into the interior of the chamber. As the hydraulic oil is sucked from the bottom of the oil storage tank component 3, the pushed hydraulic oil will pass through the first filter plate 331. Because the hydraulic oil will precipitate solids after long-term use Sedimentation, so when the hydraulic oil passes through the first filter plate 331, the solid sediment will be filtered above the first filter plate 331, and with the reciprocating rise and fall of the cover plate 362, the return spring 335 will repeatedly push the second filter plate 332, and then it can produce an extrusion effect on the solid sediment on the upper surface of the first filter plate 331, and the solid sediment is squeezed and collected. Then the workers can regularly disassemble the oil storage tank cover 33 for cleaning and maintenance. It can automatically filter impurities, ensure the purity of the hydraulic oil, and make the device work more stably.

[0045] A floating block 38 is slidably mounted in the middle of the partition 32 , and a warning rod 39 is fixedly mounted on the upper surface of the floating block 38 . The warning rod 39 is slidably mounted on the partition 32 and passes through the first filter plate 331 and the second filter plate 332 and extends to the outside of the oil storage tank cover 33 .

[0046] The float block 38 can float in the hydraulic oil. The warning rod 39 is engraved with scale lines. By observing the length of the warning rod 39 extending out of the oil storage tank component 3, it is possible to observe how much hydraulic oil is left inside the oil storage tank shell 31, thereby preventing the device from failing to work due to insufficient hydraulic oil.

[0047] A liquid inlet pipe 333 is fixedly installed on the oil storage tank cover 33, the first filter plate 331 and the second filter plate 332 are slidably mounted on the lower section of the liquid inlet pipe 333, and a sealing cover 334 is detachably installed on the top of the liquid inlet pipe 333.

[0048] When the hydraulic oil is insufficient, the sealing cover 334 can be removed, and then the hydraulic oil can be added to the inside of the oil storage tank shell 31. After adding, the sealing cover 334 can be sealed again.

[0049] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
