Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder production equipment technology, and in particular to an inclined jack mechanism for realizing rolling buffering of metal cylinder bodies. Background Technology

[0002] In the field of mechanical manufacturing, the cylinder bodies (hereinafter referred to as metal cylinder bodies) of large hydraulic cylinders and other equipment are large in size and weight (up to several tons). During the turning process, the metal cylinder bodies need to be frequently transferred with the assistance of lifting devices, which is inefficient and cumbersome. Based on this, the inventors used an inclined transfer roller to realize the self-weight rolling transfer of the metal cylinder body. However, since the metal cylinder body of a large hydraulic cylinder is too heavy and has huge impact kinetic energy, how to stably stop the metal cylinder body at a preset position is an urgent problem to be solved. Utility Model Content

[0003] Based on this, the present invention proposes an inclined top mechanism for realizing the rolling buffer of a metal cylinder, with the aim of stably stopping the metal cylinder at a preset position.

[0004] The technical solution provided by this utility model includes:

[0005] A jacking mechanism for implementing rolling damping in a metal cylinder includes:

[0006] The mounting base is fixed in place.

[0007] A swing arm, the first end of which is hinged to the mounting base about a horizontal axis;

[0008] A hydraulic damper is mounted on the swing arm, and the axis of the hydraulic damper is parallel to the axis of the swing arm.

[0009] A hydraulic cylinder, wherein the first end of the hydraulic cylinder is hinged to the mounting base, and the second end of the hydraulic cylinder is hinged to the second end of the rocker arm;

[0010] The lower limiting block is disposed on the mounting base and located at the extreme position of the downward swing of the swing arm;

[0011] A side limiting plate, which is connected to one side of the lower limiting block;

[0012] The mounting base and the side limiting plate respectively block the two sides of the swing arm.

[0013] As a further optional solution, a buffer pad is provided between the lower limiting block and the side limiting plate.

[0014] As a further optional solution, the side limiting plate, buffer pad, lower limiting block and mounting base are sequentially connected by bolts.

[0015] As a further optional solution, the gap between the mounting base and the side of the swing arm, and the gap between the side limiting plate and the side of the swing arm, are 1-3mm.

[0016] As a further optional solution, the second end of the swing arm is provided with a connecting plate with an L-shaped cross-section, and the hydraulic damper is connected to the connecting plate.

[0017] As a further optional solution, a first connecting hole is provided on the end face of the second end of the swing arm, and a second connecting hole is provided on the connecting plate. The first connecting hole is a threaded hole, and the second connecting hole is a strip hole. The length direction of the second connecting hole is arranged laterally. The first connecting hole and the second connecting hole are connected by bolts to fix the connecting plate on the end face of the second end of the swing arm.

[0018] Compared with the prior art, this application has at least the following advantages:

[0019] This inclined jacking mechanism can absorb and dissipate the huge impact kinetic energy of the metal cylinder through a hydraulic damper, achieving controllable and flexible deceleration, and finally stopping the metal cylinder stably at the preset position, providing a positioning reference for subsequent automated processing operations.

[0020] The mounting base and the side limiting plate are respectively located closely on both sides of the swing arm, forming a stable double-sided constraint structure, which greatly enhances the lateral stiffness and overall stability of the swing arm when subjected to huge impacts, effectively suppresses the swaying or twisting that may occur under off-center load impacts, ensures the smooth and reliable buffering process, and significantly extends the service life of the mechanism.

[0021] After completing the stopping task, the hydraulic cylinder can drive the swing arm to swing downwards to the position defined by the lower limit block, thereby making way for the metal cylinder body and facilitating subsequent processing. Attached Figure Description

[0028] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0032] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0033] refer to Figures 1-4An embodiment of this utility model shows a sloping top mechanism for realizing rolling buffer of a metal cylinder. The sloping top mechanism 700 includes a mounting base 710, a rocker arm 720, a hydraulic damper 730, a hydraulic cylinder 740, a lower limiting block 750, and a side limiting block 760.

[0034] The mounting base 710 is fixedly installed; the first end of the swing arm 720 is hinged to the mounting base 710 around a horizontal axis; the hydraulic damper 730 is installed on the swing arm 720, and the axis of the hydraulic damper 730 is parallel to the axis of the swing arm 720; the first end of the hydraulic cylinder 740 is hinged to the mounting base 710, and the second end of the hydraulic cylinder 740 is hinged to the second end of the swing arm 720; the lower limiting block 750 is installed on the mounting base 710 and is located at the extreme position of the downward swing of the swing arm 720; the side limiting plate is connected to one side of the lower limiting block 750; wherein the mounting base 710 and the side limiting plate respectively block both sides of the swing arm 720.

[0035] like Figure 1 As shown, the metal cylinder G is located on an inclined transfer track 210, and the metal cylinder G rolls on the transfer track 210 by its own weight. The inclined jacking mechanism 700 is set at a preset position on the transfer track 210 where the metal cylinder G needs to stop. Multiple inclined jacking mechanisms 700 can be set and arranged laterally.

[0036] In the initial state, hydraulic cylinder 740 pushes out the swing arm 720 equipped with hydraulic damper 730, causing the hydraulic damper 730 to block the movement path of the metal rod. When the metal cylinder G impacts the hydraulic damper 730, the damper smoothly decelerates it through hydraulic resistance. During this process, the mounting base 710 and the side limiting plate are located on both sides of the swing arm 720, forming a double-sided constraint structure, which enhances the lateral stability of the swing arm 720 system, avoids swaying when subjected to the impact of heavy workpieces (i.e., metal cylinder G), and ensures that the metal cylinder G can be stably stopped at the preset position. After completing the stopping task, hydraulic cylinder 740 causes the swing arm 720 to swing downward to the position defined by the lower limiting block 750, causing the swing arm 720 and hydraulic damper 730 to retract below the transfer roller 210, making way for subsequent processes.

[0037] Furthermore, a buffer pad 770 is provided between the lower limiting block 750 and the side limiting plate. The buffer pad 770 can be an engineering material with high elasticity, wear resistance, and impact resistance, such as polyurethane, nylon, or nitrile rubber. This buffer pad 770 is used to absorb the impact energy between the swing arm 720 and the side limiting plate when the swing arm 720 is impacted, effectively reducing noise and vibration at the moment of contact.

[0038] Furthermore, the gap between the mounting base 710 and the side of the swing arm 720, and the gap between the side limiting plate and the side of the swing arm 720, are 1-3mm. This small gap ensures that the swing arm 720 can swing freely while limiting its lateral sway space, thereby further improving the stability during operation.

[0039] Furthermore, an L-shaped connecting plate 780 is provided on the end face of the second end of the swing arm 720, and the hydraulic damper 730 is connected to the connecting plate 780. The L-shaped structure of the connecting plate 780 enhances its bending strength and provides a stable connection bridge between the hydraulic damper 730 and the swing arm 720.

[0040] Furthermore, a first connecting hole 721 is provided on the end face of the second end of the swing rod 720, and a second connecting hole 781 is provided on the connecting plate 780. The first connecting hole 721 is a threaded hole, and the second connecting hole 781 is a strip-shaped hole. The length direction of the second connecting hole 781 is arranged laterally. The first connecting hole 721 and the second connecting hole 781 are connected by bolts to fix the connecting plate 780 on the end face of the second end of the swing rod 720. Specifically, a threaded hole is provided on the end face of the swing rod 720 as the first connecting hole 721, and a transverse strip-shaped hole is provided on the connecting plate 780 as the second connecting hole 781. The two are connected by bolts. This allows the installation position of the hydraulic damper 730 in the lateral direction to be finely adjusted, facilitating precise calibration of its blocking position during installation and debugging.

[0041] In summary, this application provides a jacking mechanism for achieving rolling buffering of a metal cylinder. This jacking mechanism can absorb and dissipate the huge impact kinetic energy of the metal cylinder through a hydraulic damper, achieve controllable flexible deceleration, and finally stop the metal cylinder stably at a preset position, providing a positioning reference for subsequent automated processing operations.

[0042] The mounting base and the side limiting plate are respectively located closely on both sides of the swing arm, forming a stable double-sided constraint structure, which greatly enhances the lateral stiffness and overall stability of the swing arm when subjected to huge impacts, effectively suppresses the swaying or twisting that may occur under off-center load impacts, ensures the smooth and reliable buffering process, and significantly extends the service life of the mechanism.

[0043] After completing the stopping task, the hydraulic cylinder can drive the swing arm to swing downwards to the position defined by the lower limit block, thereby making way for the metal cylinder body and facilitating subsequent processing.

[0044] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
