Description

Technical Field

[0001] This invention relates to the field of cylinder technology, and more specifically, to a hydraulic cylinder barrel with a rotatable connecting hole. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating or oscillating motion. It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device and has no transmission backlash, resulting in smooth movement. Therefore, it is widely used in the hydraulic systems of various machines. A hydraulic cylinder includes a cylinder barrel, which guides and supports the internal structure of the hydraulic cylinder.

[0003] Among the existing published documents, patent publication number CN111660032A discloses a hydraulic cylinder barrel for reducing welding deformation. This patent addresses the issue of cylinder barrel deformation due to high stress, and the tendency for residual particles to adhere to the cylinder barrel surface. If the cylinder barrel is not properly cleaned before welding, these residual particles can form pore cores and uneven welding cores, resulting in pores at the cylinder barrel seams. Under high-pressure hydraulic fluid, this can easily lead to cylinder barrel deformation and weld leaks. This patent increases the cylinder barrel's fatigue load capacity by using a combination of weld penetration grooves, stepped holes, connectors, and expansion sealant to achieve an interference fit. During the cylinder barrel welding process, this ensures fusion and depth at the weld root, avoids weld defects, and significantly reduces welding stress on the cylinder barrel. It also eliminates the risks of cracks, pores, deformation, and stress deformation between the cylinder head, cylinder bottom, oil inlet, oil outlet, and the cylinder barrel body. However, this patent has the following drawbacks.

[0004] Although the aforementioned hydraulic cylinder barrel can be installed in different directions during use, the telescopic rod can only be pushed stably in one direction and cannot change the guiding and pushing direction of the telescopic rod. Moreover, the hydraulic cylinder barrel can only provide lateral guidance for the telescopic rod. For hydraulic telescopic rods that require L-shaped guidance, it is difficult to switch from lateral to longitudinal support. This results in significant limitations in the use of hydraulic cylinders. Therefore, it is necessary to provide a hydraulic cylinder barrel with a rotatable connection hole. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a hydraulic cylinder barrel with a rotatable connecting hole.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic cylinder barrel with a rotatable connection hole, comprising a hydraulic cylinder, a piston pusher plate horizontally slidably connected inside the hydraulic cylinder, a telescopic rod fixed inside the piston pusher plate, a tangential mechanism at one end of the telescopic rod, and an adjustment and reversing mechanism at the outer wall of the telescopic rod located on one side of the piston pusher plate;

[0007] The switching mechanism includes a support block disposed at one end of the telescopic rod, a support ring disposed on one side of the support block, a limiting collar welded to the inner wall of the support ring, a limiting rotating shaft connected inside the limiting collar, a concave rotating rod welded to one end of the limiting rotating shaft, a support shaft rotatably connected inside the concave rotating rod via a bearing, a reversing push assembly disposed on the outer wall of the support shaft, the telescopic rod and the support ring being welded and fixed to the support block, and the telescopic rod, the support ring and the support block being made of stainless steel, the inner wall of the limiting collar being rotatably connected to the outer wall of the limiting rotating shaft, and both the outer wall of the limiting rotating shaft and the inner wall of the limiting collar being polished.

[0008] Preferably, the top end of the hydraulic cylinder is fixedly connected to two oil pressure holes arranged equidistantly from left to right, and both oil pressure holes are connected to the hydraulic cylinder. One end of the hydraulic cylinder is connected to a support base, and the support base and the hydraulic cylinder are fixedly connected by bolts. The bottom end of the hydraulic cylinder is welded with a mounting block, which is made of stainless steel.

[0009] Preferably, the reversing push assembly includes a hinged rotating rod disposed on the outer wall of the support shaft, a support shaft rod rotatably connected inside the hinged rotating rod and near one end thereof, a concave block welded to the bottom end of the support shaft rod, a collar slider and a guide pillar disposed on one side of the concave block, the inner wall of the collar slider and the outer wall of the guide pillar being horizontally slidably connected, a concave sliding push block welded to one side of the collar slider, and a connecting block welded to one side of the outer wall of the concave sliding push block, a connecting hole being provided through the top of the connecting block, a collar rotating rod slidably connected to the outer wall of the collar slider, the hinged rotating rod being rotatably connected to the support shaft, and the concave block and the collar slider being welded and fixed.

[0010] Preferably, the adjusting and reversing mechanism includes a bearing sealing ring disposed on the outer wall of the telescopic rod and located on one side of the piston push plate. A linkage gear ring is rotatably connected to the outer wall of the bearing sealing ring. Multiple welded and fixed linkage racks are distributed in a circular pattern on the outer wall of the linkage gear ring. Limiting rings for horizontal limiting of the linkage gear ring are welded to both sides of the bearing sealing ring. A driving gear ring meshes between the two linkage racks. A rotating shaft is welded inside the driving gear ring, and one end of the rotating shaft is coaxially connected to a servo reduction motor fixedly connected to one side of the outer wall of the hydraulic cylinder. Both limiting rings are rotatably connected to the linkage gear ring, and the opposite sides of the two linkage gear rings are polished.

[0011] The technical effects and advantages of this invention are as follows:

[0012] 1. This invention uses a tangential mechanism to drive the concave rotating rod to rotate the limiting rotating shaft. The limiting rotating shaft rotates stably inside the limiting shaft ring, and the support ring supports the limiting shaft ring. The telescopic rod supports the support block. The limiting rotating shaft can rotate stably inside the limiting shaft ring. The telescopic rod avoids rotation when pushing. This allows for angle adjustment of the telescopic rod, making it suitable for guiding and pushing at different angles, and thus has better applicability.

[0013] 2. The present invention uses a reversing push assembly to make the support shaft drive the hinged rotating rod to move. The support shaft rod drives the concave block to make the collar slider move along the outer wall of the guide column. The collar slider drives the concave sliding push block to make the connecting block move. This can make the connecting hole connect to the object being pushed to achieve L-shaped push. It can quickly change the pushing direction of the hydraulic telescopic rod that requires L-shaped guidance for support.

[0014] 3. The present invention uses a reversing push component to start a servo reduction motor to drive the rotating shaft to rotate. The rotating shaft drives the drive gear ring to rotate. The linkage rack drives the linkage gear ring to rotate between the two limit rings. At the same time, the bearing sealing ring can guide the linkage gear ring. The support shaft drives the concave rotating rod to rotate, which can realize automatic angle change and automatic angle switching of the limit rotating shaft, which is more convenient.

[0015] In summary, through the interaction of the above-mentioned multiple functions, firstly, the concave rotating rod drives the limiting rotating shaft to rotate, and the limiting rotating shaft rotates stably inside the limiting collar, which can adjust the angle of the telescopic rod. Secondly, it supports the rapid change of the pushing direction of the hydraulic telescopic rod that requires L-shaped guidance. Finally, it realizes automatic angle change and automatic angle switching of the limiting rotating shaft. In summary, the cylinder can achieve multi-angle L-shaped pushing and has better applicability. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] As attached Figure 1-8The diagram shows a hydraulic cylinder barrel with a rotatable connection hole. This cylinder barrel is equipped with a tangential mechanism, an adjusting and reversing mechanism, and a reversing push assembly. The arrangement of these mechanisms and assemblies allows the concave rotating rod to drive the limiting rotating shaft to rotate. The limiting rotating shaft rotates stably within the limiting collar, enabling angle adjustment of the telescopic rod. It then supports the rapid change of the pushing direction of the hydraulic telescopic rod requiring L-shaped guidance. Finally, it automatically changes and switches the angle of the limiting rotating shaft. This allows the cylinder barrel to perform multi-angle L-shaped pushes, improving its applicability. The specific structural settings of each mechanism and assembly are as follows:

[0027] In some embodiments, as shown in the appendix Figure 1-8 As shown, a tangential mechanism is provided at one end of the telescopic rod 2, and an adjustment and reversing mechanism is provided on the outer wall of the telescopic rod 2 at a position on one side of the piston push disk 3; the switching mechanism includes a support block 4 provided at one end of the telescopic rod 2, a support ring 5 provided on one side of the support block 4, a limit ring 6 welded to the inner wall of the support ring 5, a limit rotating shaft 7 connected inside the limit ring 6, a concave rotating rod 8 welded to one end of the limit rotating shaft 7, a support shaft 9 rotatably connected inside the concave rotating rod 8 through a bearing, and a reversing push assembly provided on the outer wall of the support shaft 9.

[0028] In some embodiments, as shown in the appendix Figure 1-2 As shown, the top of the hydraulic cylinder 1 is fixedly connected to two hydraulic pressure holes 10 arranged equidistantly from left to right, and both hydraulic pressure holes 10 are connected to the hydraulic cylinder 1 so that the piston push plate 3 can be easily adjusted to achieve normal use of the hydraulic cylinder. One end of the hydraulic cylinder 1 is connected to a support base 11, and the support base 11 is fixedly connected to the hydraulic cylinder 1 by bolts so that the support base 11 can provide lateral support for the hydraulic cylinder 1 and increase the stability of the hydraulic cylinder 1. The bottom end of the hydraulic cylinder 1 is welded with a mounting block 12, which is made of stainless steel so that the mounting block 12 can be fixed in a designated position by bolts. In this way, the position of the hydraulic cylinder 1 can be fixed.

[0029] In some embodiments, as shown in the appendix Figure 3-6As shown, the reversing push assembly includes a hinged rotating rod 13 disposed on the outer wall of the support shaft 9. A support shaft rod 14 is rotatably connected inside the hinged rotating rod 13 and near one end thereon. A concave block 15 is welded to the bottom end of the support shaft rod 14. A collar slider 16 and a guide pillar 17 are provided on one side of the concave block 15. The inner wall of the collar slider 16 and the outer wall of the guide pillar 17 are horizontally slidably connected. A concave sliding push block 18 is welded to one side of the collar slider 16, and a connecting block 19 is welded to one side of the outer wall of the concave sliding push block 18. A connecting block 19 is formed through the top of the connecting block 19. The outer wall of the collar slider 16 is slidably connected to the hole 20, and the collar rotating rod 21 is rotatably connected to the hinge rotating rod 13 and the support shaft 9. The concave block 15 is welded and fixed to the collar slider 16 so that the support shaft 9 can drive the hinge rotating rod 13 to move under the action of hydraulic pressure. The support shaft rod 14 drives the concave block 15 to make the collar slider 16 move along the outer wall of the guide pillar 17. The collar slider 16 drives the concave sliding push block 18 to make the connecting block 19 move. The connecting block 19 drives the connecting hole 20 to move, which converts the lateral pushing force of the connecting block 19 into the longitudinal pushing force.

[0030] In some embodiments, as shown in the appendix Figure 2-8 As shown, the adjusting reversing mechanism includes a bearing sealing ring 22 located on the outer wall of the telescopic rod 2 and on one side of the piston push plate 3. A linkage gear ring 23 is rotatably connected to the outer wall of the bearing sealing ring 22. Multiple welded and fixed linkage racks 25 are evenly distributed in a circular pattern on the outer wall of the linkage gear ring 23. Limiting rings 24 are welded to both sides of the bearing sealing ring 22 to horizontally limit the linkage gear ring 23. A drive gear ring 26 meshes between two linkage racks 25. A rotating shaft 27 is welded inside the drive gear ring 26, and one end of the rotating shaft 27 is coaxially connected to a servo reduction motor 2 fixedly connected to one side of the outer wall of the hydraulic cylinder 1. 8. Both limiting rings 24 are rotatably connected to the linkage gear ring 23, and the opposite sides of the two linkage gear rings 23 are polished to facilitate the starting of the servo reduction motor 28 to drive the rotating shaft 27 to rotate, drive the gear ring 26 to drive multiple linkage racks 25 to achieve meshing transmission, and the linkage racks 25 drive the linkage gear ring 23 to rotate between the two limiting rings 24 to ensure that the linkage gear ring 23 rotates stably outside the bearing sealing ring 22. The linkage gear ring 23 drives the collar rotating rod 21 to rotate, the guide support 17 causes the collar slider 16 to rotate, the collar slider 16 drives the concave block 15 to rotate the support shaft 14, and the support shaft 9 drives the concave rotating rod 8 to rotate.

[0031] The working principle of this invention is as follows:

[0032] When the cylinder angle is adjusted and reversed, the mounting block 12 is fixed in the designated position by bolts, so that the position of the hydraulic cylinder 1 can be fixed. Then, the servo reduction motor 28 is started to drive the rotating shaft 27 to rotate. The rotating shaft 27 drives the drive gear ring 26 to rotate. At the same time, the drive gear ring 26 drives multiple linkage racks 25 to achieve meshing transmission. The linkage racks 25 drive the linkage gear ring 23 to rotate between the two limit rings 24. The bearing sealing ring 22 can guide the linkage gear ring 23 to ensure that the linkage gear ring 23 rotates stably outside the bearing sealing ring 22. The linkage gear ring 23 drives the collar rotating rod 21 to rotate. The collar rotating rod 21 drives the guide support 17 to rotate the collar slider 16. The collar slider 16 drives the concave block 15 to rotate the support shaft 14. The support shaft 14 drives the hinge rotating rod 13 to rotate the support shaft 9. The support shaft 9 drives the concave rotating rod 8 to rotate.

[0033] When the push end angle is rotated, the concave rotating rod 8 drives the limiting rotating shaft 7 to rotate, and the limiting rotating shaft 7 rotates stably inside the limiting shaft ring 6. The support ring 5 supports the limiting shaft ring 6, the telescopic rod 2 supports the support block 4, and the support block 4 supports the support ring 5. The limiting rotating shaft 7 can rotate stably inside the limiting shaft ring 6, realizing multi-angle adjustment of the position of the limiting rotating shaft 7.

[0034] When the L-shaped pusher reverses direction, when oil is introduced into the rightmost oil pressure port 10 and the leftmost oil pressure port 10 is blocked, the hydraulic cylinder 1 will be filled with oil. This causes the piston to push the disc 3 to move to the left along the inside of the bearing sealing ring 22. The telescopic rod 2 drives the support block 4, causing the support ring 5 to move. The support ring 5 drives the limiting shaft ring 6, causing the limiting rotating shaft 7 to move. The limiting rotating shaft 7 drives the concave rotating rod 8, causing the support shaft 9 to move. This allows the support shaft 9 to drive the hinged rotating rod 13 to move. Rod 13 drives support shaft rod 14 to move forward. Support shaft rod 14 drives concave block 15 to move collar slider 16 along the outer wall of guide post 17. At the same time, collar slider 16 moves guided by the inner wall of collar rotating rod 21. Collar slider 16 drives concave sliding push block 18 to move connecting block 19. Connecting block 19 drives connecting hole 20 to move. In this way, after connecting hole 20 is connected to the pushed object, it can achieve L-shaped push on connecting block 19, converting the lateral pushing force into the longitudinal pushing force.
