Description

Technical Field

[0001] The invention relates to the technical field of oil cylinders, in particular to a high-speed composite oil cylinder driven by a servo valve. Background Art

[0002] Most oil cylinders are composed of a cylinder liner, a piston, a piston rod and a guide sleeve. Hydraulic oil is injected into the cylinder liner so that the hydraulic oil enters the cylinder liner and pushes the piston to move inside the cylinder liner, thereby causing the piston to drive the piston rod to move. The hydraulic oil supports the piston so that the piston rod has enough power to lift objects when moving. However, since the oil cylinder mainly uses hydraulic oil to support the piston, when a large piston is used, it is necessary to use a high-power power equipment to inject oil into the cylinder liner. In addition, since the oil inlet on the cylinder liner is limited in size, and in order to increase the power of the oil cylinder, the hydraulic oil needs to occupy a certain space inside the cylinder liner, resulting in a low oil inlet rate during general oil injection. It takes a certain amount of time for the hydraulic oil to fill the internal space of the cylinder liner, which results in a slow lifting speed of the general oil cylinder, which is more inconvenient.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 9 In an embodiment of the present invention, a servo valve driven high-speed composite oil cylinder includes a cylinder sleeve 100, and the cylinder sleeve 100 is an open structure at one end, a cylinder piston 120 is slidably sleeved inside the cylinder sleeve 100, and a guide sleeve 110 is fixedly sleeved at one end of the cylinder sleeve 100, a piston rod 121 is fixedly sleeved on the cylinder piston 120, and an outer wall of the piston rod 121 is slidably sleeved with an inner wall of the cylinder piston 120, a climbing mechanism 200 is arranged inside the cylinder sleeve 100, and a filling mechanism 300 is arranged on one side of the cylinder sleeve 100, and the filling mechanism 300 is matched with a power mechanism 400;

[0033] The climbing mechanism 200 includes two U-shaped frames 210, and the adjacent sides of the two U-shaped frames 210 are respectively fixedly connected to the top and bottom ends of the oil cylinder piston 120, and the two arms of the two U-shaped frames 210 are rotatably connected with a rotating wheel 211, and the outer walls of the two rotating wheels 211 are each provided with an oil groove 212, and the inner walls of the two oil grooves 212 are each fixedly connected with a plurality of evenly distributed abutment plates 213, and one side of the two U-shaped frames 210 is provided with a U-shaped plate 220, and one end of the two arms of the two U-shaped plates 220 is respectively fixedly connected to the one side of the two arms of the adjacent U-shaped frames 210, and the two U-shaped plates 220 A connecting hole 221 is provided on an inner wall, and an injection frame 222 is fixedly connected to an inner wall of each of the two U-shaped plates 220. The interiors of the two injection frames 222 are connected to the interiors of adjacent connecting holes 221, and one end of each of the two injection frames 222 is an arc surface. One end of each of the two injection frames 222 is in contact with the outer wall of the adjacent runner 211. A cutting groove 101 is provided on the inner wall of the cylinder sleeve 100, and a fixing plate 240 is fixedly connected to one side of the cutting groove 101. A plurality of clamping grooves 241 are provided on one side of the fixing plate 240, and one end of the abutment plate 213 is movably clamped in the interior of the adjacent clamping groove 241.

[0034] Specifically, by injecting hydraulic oil into any injection frame 222, the oil is ejected through the injection frame 222 to push the adjacent abutment plate 213 to drive the adjacent rotating wheel 211 to rotate, so that when the rotating wheel 211 rotates, the multiple abutment plates 213 on the rotating wheel 211 are sequentially stuck in the adjacent card grooves 241, so that the rotating wheel 211 can move stably on the fixed plate 240, thereby controlling the cylinder piston 120 and the piston rod 121 to quickly climb or descend in the cylinder sleeve 100, thereby facilitating the rapid lifting and lowering of the movable end of the cylinder. When the cylinder is in use, only one injection frame 222 needs to be injected with hydraulic oil to drive the cylinder piston 120 to move in the cylinder sleeve 100. When hydraulic oil is injected into the injection frame 222 above the cylinder piston 120, the cylinder piston 120 moves downward in the cylinder sleeve 100. When hydraulic oil is injected into the injection frame 222 below the cylinder piston 120, the cylinder piston 120 moves upward in the cylinder sleeve 100.

[0035] Embodiment 1

[0036] like Figure 4-5 As shown, in this embodiment, the plurality of abutment plates 213 are all arranged obliquely.

[0037] In this embodiment, when the inclined abutment plate 213 is impacted by the oil sprayed from the adjacent spray frame 222 , it can more easily drive the adjacent rotating wheel 211 to rotate by virtue of its inclined state.

[0038] like Figure 2 and Figure 7As shown, in this embodiment, the filling mechanism 300 includes a box body 310, and both ends of one side of the box body 310 are fixedly connected with connecting pipes 311, one end of the two connecting pipes 311 is respectively fixedly connected to the top and bottom ends of the outer wall of the cylinder sleeve 100, and the interiors of the two connecting pipes 311, the interior of the cylinder sleeve 100 and the interior of the box body 310 are all connected, and a piston plate 320 is slidably sleeved inside the box body 310.

[0039] In specific implementation, the box body 310 contains hydraulic oil, and the hydraulic oil in the box body 310 can enter the space on the opposite sides of the cylinder piston 120 through the two connecting pipes 311. When any injection frame 222 sprays hydraulic oil, due to the small spray port of the injection frame 222, the amount of hydraulic oil sprayed is small and it is difficult to fill the space between the cylinder piston 120 and the cylinder sleeve 100. In addition, since the cylinder piston 120 moves on the fixed plate 240 at a fast speed by relying on the rotating wheel 211 and the card slot 241, the size of the space between the top and bottom ends of the cylinder piston 120 and the adjacent ends inside the cylinder sleeve 100 changes greatly after the cylinder piston 120 moves. The space between the top and bottom ends of the cylinder piston 120 and the adjacent ends inside the cylinder sleeve 100 needs to be filled with hydraulic oil to ensure that when the cylinder piston 120 stops moving, The space between the cylinder piston 120 and the cylinder sleeve 100 is not easy to change position because the space between the cylinder piston 120 and the cylinder sleeve 100 is filled with hydraulic oil. The space between the cylinder piston 120 and the adjacent ends inside the cylinder sleeve 100 can be filled with the hydraulic oil inside the box body 310. When the cylinder piston 120 moves, the cylinder piston 120 will push the hydraulic oil at one end to flow back into the box body 310, and the hydraulic oil returning to the box body 310 pushes the piston plate 320, driving the hydraulic oil inside the box body 310 to enter the other end of the cylinder piston 120. At the same time, when the cylinder piston 120 moves, the other end generates negative pressure to suck the hydraulic oil inside the box body 310, so that there is always hydraulic oil at both ends of the cylinder piston 120 to fill the space between the cylinder piston 120 and the cylinder sleeve 100, ensuring that the piston rod 121 of the cylinder is not easy to move when stationary.

[0040] like Figure 2-3As shown, in this embodiment, the power mechanism 400 includes two tube bodies 410, and both tube bodies 410 have one-end sealing structures, wherein one end of one tube body 410 is fixedly connected to a hollow ring 420, and the bottom end of the outer wall of the hollow ring 420 is fixedly sleeved with a connecting tube 430, and the bottom end of the outer wall of the connecting tube 430 and one end of the other tube body 410 are fixedly connected to a conduit, one end of the two conduits are respectively fixedly connected to the top and bottom ends of the outer wall of the cylinder sleeve 100, and the interiors of the two conduits are connected to the interior of the cylinder sleeve 100, wherein the interior of one conduit is connected to the interior of the connecting tube 430, and the interior of the other conduit is connected to the interior of the other tube body 410. The top and bottom ends of the inner wall of the cylinder sleeve 100 are fixedly connected with a connecting shell 230, and the interiors of the two connecting shells 230 are respectively connected to the interiors of the two conduits, one side of the two connecting shells 230 is fixedly connected with a hose 231, and one end of the two hoses 231 is respectively fixedly connected to one side of the two U-shaped plates 220, the interiors of the two hoses 231 are connected with the interiors of the adjacent connecting shells 230 and the interiors of the connecting hole 221, the inner bottom surface of the cylinder sleeve 100 is fixedly connected with an insertion rod 102, and a hole 122 is opened at the bottom end of the piston rod 121, the outer wall of the insertion rod 102 is slidably connected with the inner wall of the hole 122, and the bottom end of the piston rod 121 is a hemispherical structure.

[0041] In specific implementation, the two tube bodies 410 are used to connect with the servo valve. When in use, the servo valve can be used to make any tube body 410 spray hydraulic oil into the adjacent connecting shell 230, and the hydraulic oil can be quickly sprayed out from the adjacent injection frame 222 through the hose 231 with a thinner diameter, thereby driving the adjacent runner 211 to rotate and control the movement of the oil cylinder piston 120. The tube body 410 that has not sprayed out is flooded with excess hydraulic oil in the cylinder sleeve 100, and the excess hydraulic oil in the cylinder sleeve 100 is recovered. By inserting the insertion rod 102 into the socket 122, the insertion rod 102 can further limit the piston rod 121, thereby improving the movement stability of the piston rod 121. At the same time, when the piston rod 121 moves, the insertion rod 102 will never be separated from the socket 122, so that the hose 231 is not easy to enter the bottom end of the piston rod 121 and affect the movement of the piston rod 121. When the piston rod 121 is reset, the adjacent hose 231 can be pushed away by the hemispherical bottom end until the bottom end of the piston rod 121 contacts the inner bottom surface of the cylinder sleeve 100.

[0042] like Figure 6-8As shown, in this embodiment, a rotating rod 330 is rotatably connected between the inner bottom surface and the inner top surface of the box body 310, and a spiral groove is provided on the outer wall of the rotating rod 330, a circular hole is provided at the center of the top surface of the piston plate 320, and the rotating rod 330 is located inside the circular hole, and two protrusions 321 are fixedly connected to the inner side wall of the circular hole, and the two protrusions 321 are slidably engaged in the spiral groove, and a plurality of U-shaped tubes 421 are provided on the outer side wall of the hollow ring 420, and one end of the plurality of U-shaped tubes 421 passes through the outer side wall of a tube body 410 and is fixedly connected to a tube body 410, and the other end passes through the hollow ring 421. 0 outer wall and is fixedly connected to the outer wall of the hollow ring 420, the inner wall of the hollow ring 420 is provided with a plurality of injection ports 422, the inner bottom center of the connecting tube 430 is rotatably connected to a guide rod 440, and the top of the guide rod 440 is located at the center of the hollow ring 420, a plurality of guide vanes 441 are fixedly connected to the top of the guide rod 440, and the bottom end of the guide rod 440 passes through the bottom surface of the connecting tube 430, the bottom end of the rotating rod 330 passes through the bottom surface of the box body 310, and the bottom ends of the rotating rod 330 and the guide rod 440 are fixedly sleeved with gears 442, and a toothed belt 443 is rotatably sleeved between the outer sides of the two gears 442.

[0043] In specific implementation, when in use, when the hydraulic oil in a tube body 410 is sprayed, the hydraulic oil enters the inside of the hollow ring 420 through multiple U-shaped tubes 421, and the hydraulic oil is then sprayed out through multiple injection ports 422 to impact multiple guide vanes 441, so that the multiple guide vanes 441 are rotated by the impact of the hydraulic oil, driving the guide rod 440 to rotate, and the guide rod 440 drives the rotating rod 330 to rotate synchronously through the gear 442 and the toothed belt 443, so that the rotating rod 330 drives the piston plate 320 to move inside the box body 310 by relying on the spiral groove and the two protrusions 321 on the piston plate 320, and the hydraulic oil falling into the connecting tube 430 will rely on the adjacent conduit and the adjacent hose 231 to be sprayed from the adjacent injection frame 222, so that the rotating rod 330 can drive the piston plate 320 to move, and promote the hydraulic oil inside the box body 310 to move synchronously with the movement of the cylinder piston 120, so that When the cylinder piston 120 moves up, the piston plate 320 moves down, and when the cylinder piston 120 moves down, the piston plate 320 moves up, ensuring that the hydraulic oil in the cylinder sleeve 100 is always full when the cylinder piston 120 moves, and the piston plate 320 pushes the hydraulic oil in the box body 310 to be injected into the cylinder sleeve 100, providing auxiliary support force for the cylinder piston 120, so that when there is an object at the piston rod 121, the piston plate 320 cooperates to push the hydraulic oil in the box body 310 to input into the cylinder sleeve 100 to support the cylinder piston 120, so that the piston rod 121 can have enough power to push the object to move, and when the other pipe body 410 sprays hydraulic oil, the hydraulic oil in the cylinder sleeve 100 can flow into the connecting tube 430 to impact the guide vane 441 to drive the guide rod 440 to reverse, and the specific style of the guide vane 441 can be customized as needed, and the inner diameter of the connecting pipe 311 is larger than the diameter of the guide pipe.

[0044] Embodiment 2

[0045] On the basis of the first embodiment, the guide plate 423 is provided to increase the impact force of the hydraulic oil on the guide blade 441 .

[0046] like Figure 1 and Fig. 9 As shown, in this embodiment, a plurality of guide plates 423 are fixedly connected between the inner top surface and the inner bottom surface of the hollow ring 420, and any guide plate 423 is located between two adjacent injection ports 422. A mounting plate 130 is provided at the bottom of the cylinder sleeve 100, and a support rod is fixedly connected between the bottom end of the cylinder sleeve 100 and the bottom end of the box body 310 and the top surface of the mounting plate 130.

[0047] In a specific implementation, when the hydraulic oil in a tube body 410 enters the interior of the hollow ring 420 through multiple U-shaped tubes 421, it can increase the impact force ejected from the injection port 422 by flowing through the guide plate 423, thereby increasing the rotational power of the rotating rod 330. The mounting plate 130 facilitates the user to install the cylinder and the box body 310.

[0048] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
