Abstract
Description
Technical Field
[0001] This utility model relates to the field of steering cylinder technology, and more specifically, to a steering cylinder assembly device. Background Technology
[0002] A steering cylinder is an actuator that directly converts hydraulic energy into wheel rotation angle, commonly found in the front or rear axles of forklifts, loaders, tractors, and electric scooters. It functions as both a cylinder and a steering knuckle, exhibiting high integration and requiring significantly higher positioning accuracy, impact resistance, and sealing lifespan than ordinary lifting cylinders. Therefore, during the assembly of a steering cylinder, it is crucial to ensure accurate and reliable limit positioning.
[0003] Patent CN217596547U discloses a clamping mechanism for machining steering cylinders, including a base plate with side plates fixedly installed on both sides. It also includes a support mechanism, a clamping mechanism, an adjusting mechanism, and a locking mechanism. The adjusting mechanism is located on the side plates and includes a motor fixedly installed on the side plates. The motor output end is fixedly connected to a rotating shaft, and the end of the rotating shaft is fixedly connected to a locking plate. The adjusting mechanism allows adjustment of the machining position of the steering cylinder clamped by the clamping mechanism. The locking mechanism solves the problem in existing technologies where changing the machining position requires repeatedly loosening and tightening nuts, which is cumbersome and prone to stripping threads.
[0004] Although the above-mentioned device can clamp the steering cylinder from both sides through the clamping mechanism, the contact area between the clamping mechanism and the steering cylinder is limited, and it is also unable to limit the top of the end cover during the assembly of the steering cylinder barrel and the end cover. This causes the steering cylinder to shift due to pressure during the assembly process, ultimately affecting the quality of the finished special cylinder after assembly. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a steering cylinder assembly device that, based on the side positioning component and the side limiting component limiting the cylinder barrel from both sides respectively, further limits it from the top of the steering cylinder end cover, ensuring that the steering cylinder will not be displaced under force during assembly, thereby improving the quality of the assembled product.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A steering cylinder assembly device includes a mounting base, a main positioning assembly mounted on the mounting base, and side positioning assemblies and side limiting assemblies disposed on both sides of the main positioning assembly. The main positioning assembly includes mounting brackets symmetrically mounted on the mounting base and a support frame disposed between the mounting brackets. The support frame has a main positioning hole. The side positioning assembly includes a first mounting seat, a side positioning cylinder, a side limiting plate connected to the side positioning cylinder, and a first mounting seat and a main positioning guide rod mounted on the side limiting plate. The side limiting assembly includes a second mounting seat, a limiting cylinder and a pressing cylinder mounted on the second mounting seat, a limiting plate connected to the limiting cylinder, and a pressing member connected to the pressing cylinder. A pressing guide rod is connected to the end of the pressing member, and a pressing block is connected to the end of the pressing guide rod.
[0008] The present invention is further configured such that: a first abutting member and a main positioning cylinder are installed on the side wall of the mounting bracket, the first abutting member is located above the main positioning cylinder, a first abutting groove is provided on the first abutting member, and a positioning member is connected to the output end of the main positioning cylinder.
[0009] The present invention is further configured such that: a first abutting block and a side positioning guide rod are installed on the top of the positioning member, the first abutting block corresponds to the position of the first abutting member, the side positioning guide rod is arranged in the vertical direction, and the side positioning guide rod is located on one side of the main positioning component.
[0010] The present invention is further configured such that: the main positioning guide rod is arranged in a vertical direction, the main positioning guide rod passes through the main positioning hole, and the side limiting plate is symmetrically installed with limiting frames on both sides, and the limiting frame is equipped with a mating head on the side near the center of the mounting base.
[0011] The present invention is further configured such that: the side positioning cylinder is installed on the side wall of the first mounting base, two clamping cylinders are symmetrically installed on the top of the side limiting plate, the output end of the clamping cylinder is connected to a clamping component, and a clamping through hole is provided on the clamping component.
[0012] The present invention is further configured such that: a side limiting strip is detachably installed between the clamping member and the mating head, and the mating head extends through the side limiting strip into the inside of the clamping through hole.
[0013] The present invention is further configured such that: the limiting cylinder is arranged in the horizontal direction, the pressing cylinder is arranged in the vertical direction, and the output end of the pressing cylinder is connected to the pressing component.
[0014] The beneficial effects of this utility model are:
[0015] During assembly, the steering cylinder barrel is placed on the support frame. The main positioning guide rod passes through the main positioning hole on the support frame for positioning. The side positioning cylinder drives the side limiting plate to move and abut against the side wall of the steering cylinder barrel. The limiting cylinder drives the limiting plate to move and abut against the side wall of the steering cylinder barrel, thus limiting the steering cylinder barrel from both sides. Then, the end cap is placed on the steering cylinder barrel. The downward pressing cylinder extends and retracts, causing the downward pressing block to abut against the top of the end cap, thus limiting the steering cylinder from the top of the end cap. Limiting the steering cylinder from both the side wall of the steering cylinder and the top of the end cap ensures that the steering cylinder will not shift due to force during assembly, effectively improving the quality of the assembled product.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0030] Please refer to Figure 1 and Figure 8 A steering cylinder assembly device includes a mounting base 1, a main positioning component 2 mounted on the mounting base 1, and side positioning components 3 and side limiting components 4 disposed on both sides of the main positioning component 2. During the assembly of the steering cylinder, the steering cylinder barrel is placed on the main positioning component 2, and the side positioning components 3 and side limiting components 4 limit it from both sides respectively. Then, the end cap is placed on the steering cylinder barrel, and the side limiting components 4 limit the end cap from the top to ensure that the steering cylinder will not be deflected by force during the assembly process.
[0031] Please refer to Figure 1-2 The mounting base 1 includes a horizontally arranged support frame 11 and a positioning platform 12 mounted on top of the support frame 11. The support frame 11 has a frame structure, and the positioning platform 12 is fixedly mounted on the support frame 11. A structural hole 13 is provided in the middle of the positioning platform 12, and the main positioning component 2 is installed at the position of the structural hole 13. The bottom of the main positioning component 2 is fixedly connected to the positioning platform 12. The side positioning component 3 and the side limiting component 4 are respectively fixedly mounted on the top of the positioning platform 12.
[0032] Please refer to Figure 1-3The main positioning assembly 2 includes mounting brackets 21 symmetrically mounted on the mounting base 1 and support brackets 22 disposed between the mounting brackets 21. The two mounting brackets 21 are respectively mounted on the top of the positioning platform 12, and the support brackets 22 are located above the structural hole 13. A main positioning hole 23 is provided on the support bracket 22, located at the center of the support bracket 22 and penetrating through it. A through hole is also provided on the support bracket 22 to facilitate positioning of the steering cylinder when it is placed on top of the support bracket 22. A first abutment member 24 and a main positioning cylinder 26 are mounted on the side wall of the mounting bracket 21, with the first abutment member 24 located above the main positioning cylinder 26. A first abutment groove 25 is provided on the first abutment member 24, located at the bottom of the first abutment member 24, and the first abutment groove 25 is a triangular recess. The output end of the main positioning cylinder 26 is connected to a positioning component 27. A first abutment block 28 and a side positioning guide rod 29 are mounted on the top of the positioning component 27. The first abutment block 28 is located near the side wall of the mounting bracket 21, and the side positioning guide rod 29 is located near the center of the support frame 22. The first abutment block 28 has a triangular cross-section and corresponds to the position of the first abutment component 24. The side positioning guide rod 29 is vertically oriented and located on one side of the main positioning assembly 2. The extension and retraction of the main positioning cylinder 26 synchronously drives the side positioning guide rod 29 to move vertically. A through hole is provided on the cylinder barrel of the steering cylinder corresponding to the position of the side positioning guide rod 29. When the first abutment block 28 moves to abut against the first abutment groove 25 on the first abutment component 24, the side positioning guide rod 29 can be inserted into the bottom of the steering cylinder barrel for positioning.
[0033] Please refer to Figure 1-2 and Figure 4-5 The side positioning assembly 3 includes a first mounting base 31, a side positioning cylinder 32, a side limiting plate 33 connected to the side positioning cylinder 32, and a first mounting base 31 and a main positioning guide rod 35 mounted on the side limiting plate 33. The first mounting base 31 is fixedly mounted on the top of the positioning platform 12. An auxiliary positioning frame 34 is fixedly mounted on the middle part of the first mounting base 31 near the structural hole 13, and the main positioning guide rod 35 is fixedly mounted on the auxiliary positioning frame 34. The main positioning guide rod 35 is arranged vertically and passes through the main positioning hole 23. A through hole is opened on the cylinder barrel of the steering cylinder at a position corresponding to the position of the main positioning guide rod 35. When the cylinder barrel of the steering cylinder is placed on the support frame 22, the main positioning guide rod 35 can position the cylinder barrel of the steering cylinder. The side positioning cylinder 32 is mounted on the side wall of the first mounting base 31. The side positioning cylinder 32 is arranged horizontally, and the output end of the side positioning cylinder 32 is connected to the side limiting plate 33, which is located near the structural hole 13. The extension and retraction of the side positioning cylinder 32 can synchronously drive the side limiting plate 33 to move in the horizontal direction, so that the side limiting plate 33 can abut against the side wall of the steering cylinder barrel, thereby limiting its movement.
[0034] Please refer to Figure 1-2and Figure 4-5 A limiting frame 36 is symmetrically installed on both sides of the side limiting plate 33, and the limiting frame 36 is located on both sides of the main positioning guide rod 35. A mating head 310 is installed on the side of the limiting frame 36 near the center of the mounting base 1. Two clamping cylinders 37 are symmetrically installed on the top of the side limiting plate 33. The output end of the clamping cylinder 37 is connected to a clamping component 38. The extension and retraction of the clamping cylinder 37 can drive the clamping component 38 to move synchronously. A clamping through hole 39 is opened on the clamping component 38, and the shape of the clamping through hole 39 is adapted to the mating head 310. A side limiting strip 311 is detachably installed between the clamping component 38 and the mating head 310. The side limiting strip 311 has a through hole through which the mating head 310 can pass. During installation, the side limiting strip 311 is moved by the extension and retraction of the clamping cylinder 37, which in turn moves the clamping member 38, causing the mating head 310 to extend through the side limiting strip 311 into the clamping through hole 39, thereby fixing the side limiting strip 311. When the steering cylinder barrel is placed on the support frame 22, the end of the side limiting strip 311 first contacts the side wall of the steering cylinder barrel. As the steering cylinder barrel is pushed forward, the side limiting strip 311 is gradually compressed and deformed. After the steering cylinder barrel is placed, the two side limiting strips 311 open relative to each other, clamping the steering cylinder barrel between them, thereby limiting it from the side wall of the steering cylinder barrel.
[0035] Please refer to Figure 1-2 and Figure 6-7 The side limiting assembly 4 includes a second mounting base 41, a limiting cylinder 42 and a pressing cylinder 44 mounted on the second mounting base 41, a limiting plate 43 connected to the limiting cylinder 42, and a pressing member 45 connected to the pressing cylinder 44. The limiting cylinder 42 is arranged horizontally, and the pressing cylinder 44 is arranged vertically. The output end of the limiting cylinder 42 is connected to the limiting plate 43, which is located near the structural hole 13. The extension and retraction of the limiting cylinder 42 can synchronously drive the limiting plate 43 to move horizontally, so that the limiting plate 43 can abut against the side wall of the steering cylinder barrel, thereby limiting the steering cylinder barrel. The output end of the pressing cylinder 44 is connected to the pressing member 45, and the end of the pressing member 45 is connected to a pressing guide rod 46. The end of the pressing guide rod 46 near the structural hole 13 is connected to a pressing block 47. Once the end cap is in place, the extension and retraction of the pressing cylinder 44 can drive the pressing component 45 to move synchronously until the bottom of the pressing block 47 abuts against the steering cylinder, thereby limiting it from the top of the end cap and preventing displacement during subsequent assembly.
[0036] During assembly, the steering cylinder is placed on the support frame 22. The main positioning guide rod 35 passes through the main positioning hole 23 on the support frame 22 for positioning. The side positioning cylinder 32 drives the side limiting plate 33 to move and abut against the side wall of the steering cylinder barrel. The limiting cylinder 42 drives the limiting plate 43 to move and abut against the side wall of the steering cylinder barrel, thus limiting the steering cylinder from both sides. Then, the end cap is placed on the steering cylinder barrel. The pressing cylinder 44 extends and retracts, causing the pressing block 47 to move downward and abut against the top of the steering cylinder, thus limiting the steering cylinder from the top of the end cap. Limiting the steering cylinder from the side wall of the cylinder barrel and the top of the end cap ensures that the steering cylinder will not shift due to force during assembly, effectively improving the quality of the assembled product.
