Description

A tooling for disassembling rubber bearings Technical Field

[0001] This utility model belongs to the field of bearing technology, specifically a tooling for disassembling rubber bearings. Background Technology

[0002] In the field of mechanical assembly and maintenance, disassembling rubber bearings is a common task. Rubber bearings are typically installed in various mechanical equipment for support and vibration damping. As the equipment's usage and maintenance cycles come to an end, it is necessary to disassemble the rubber bearings to replace them with new ones or perform other maintenance operations.

[0003] Traditional methods for disassembling rubber bearings primarily rely on manual operation, using tools such as hammers and crowbars. This method is not only inefficient but also prone to damaging the workpiece and the bearing itself. Operators need to spend a significant amount of time and effort to complete the disassembly task, and there are also certain safety hazards during the operation. For example, hammers may accidentally injure the operator's hands, and crowbars may cause scratches on the workpiece surface. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art; to this end, the present invention proposes a tooling for disassembling rubber bearings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rubber bearing disassembly tooling, including a worktable, wherein tooling components are provided on the surface of the worktable;

[0006] The tooling assembly includes a bottom tooling, the surface of which is mated with a workpiece;

[0007] A positioning plate is fixedly connected inside the bottom tooling. A connecting column is slidably connected to the middle of the positioning plate. A pushing plate is fixedly connected to the top of the connecting column. A spring is fixedly connected between the pushing plate and the positioning plate.

[0008] The two springs push the pusher discs to move the workpiece.

[0009] Preferably, the positioning plate is disposed in a circular groove in the bottom tooling, the top of the pushing plate is in contact with the lower surface of the workpiece, and the spring is sleeved on the connecting column.

[0010] Preferably, the tooling assembly further includes docking posts, which are fixed to both sides of the bottom of the workpiece for docking and positioning with docking holes on both sides of the bottom tooling surface;

[0011] The upper tooling slides in the middle of the workpiece and the mating hole, and is used to push the rubber bearing inside the workpiece downward.

[0012] Positioning holes are symmetrically arranged on both sides of the bottom fixture to provide docking space for the bottom fixture.

[0013] Preferably, the surface of the worktable is provided with two sets of symmetrically arranged positioning components for limiting the bottom tooling.

[0014] Preferably, the positioning component includes a slide rail, which is fixed to the surface of the worktable and has a slider slidably connected to the surface;

[0015] A limiting plate is fixed to one end of the slide rail surface;

[0016] The limiting block is fixed to the other end of the slide rail surface;

[0017] The telescopic column is fixed between the limiting plate and the slider;

[0018] Spring 1 is fitted onto the telescopic column;

[0019] Pull the handle, which is fixed to the surface of the slider;

[0020] The limiting post is fixed to the middle of one side of the slider.

[0021] Preferably, the limiting post slides within the positioning hole, and the spring is disposed between the limiting plate and the slider.

[0022] Preferably, each of the four sides of the workbench surface is fixedly connected to a column, and the other end of the four columns is fixedly connected to a top plate.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] (1) This utility model utilizes the counter-force of spring two to push the workpiece away from the bottom fixture automatically. At the same time, the upper fixture can quickly push the rubber bearing out of the workpiece under the action of external force, thereby reducing the manual operation links and increasing the disassembly speed. Compared with the traditional manual disassembly method, the work efficiency can be increased several times, which can effectively shorten the maintenance cycle of the equipment.

[0027] (2) This practical tooling assembly, through the precise docking and positioning of the docking column and the docking hole, and the structural feature that the diameter of the upper tooling is the same as the inner diameter of the workpiece, can ensure the accurate position of the workpiece and the rubber bearing during the disassembly process, avoid collision and squeezing damage caused by position deviation, and the uniform force of the push disk component also enables the rubber bearing to be smoothly removed from the workpiece, effectively protecting the quality of the workpiece and the bearing and reducing maintenance costs.

[0028] (3) The combined use of this practical tooling assembly and positioning assembly allows the entire disassembly process to take place within a relatively stable structural system. Operators do not need to directly touch the workpiece and the main working area of ​​the disassembly tool with their hands, reducing the risk of injury. Attached Figure Description

[0035] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Example 1

[0037] Please refer to Figures 1-5. This application provides a rubber bearing disassembly tooling, including a worktable 1, on the surface of which a tooling assembly 4 is provided.

[0038] Tooling assembly 4 includes a bottom tooling 40, on the surface of which a workpiece 42 is mated;

[0039] A positioning plate 47 is fixedly connected inside the bottom tooling 40. A connecting column 45 is slidably connected to the middle of the positioning plate 47. A pushing plate 44 is fixedly connected to the top of the connecting column 45. A spring 46 is fixedly connected between the pushing plate 44 and the positioning plate 47.

[0040] Spring 46 pushes the pusher disc 44, thereby pushing the workpiece 42.

[0041] It should be noted that a rubber bearing is installed inside workpiece 42;

[0042] The push plate 44, connecting column 45, spring 46, and positioning plate 47 are all provided in four sets and arranged in a ring, so that the workpiece 42 can be pushed out stably from all sides, avoiding the workpiece 42 from sticking to the surface of the bottom tooling 40 and being difficult to remove, thereby improving the efficiency of rubber shaft disassembly.

[0043] In this embodiment, preferably, the positioning disk 47 is disposed in the circular groove in the bottom tooling 40, the top of the pushing disk 44 contacts the lower surface of the workpiece 42, and the spring 46 is sleeved on the connecting post 45.

[0044] In this embodiment, preferably, the tooling assembly 4 further includes docking posts 43, which are fixed to both sides of the bottom of the workpiece 42 for docking and positioning with the docking holes 48 on both sides of the surface of the bottom tooling 40.

[0045] The upper tooling 41 slides in the middle of the workpiece 42 and the mating hole 48, and is used to push the rubber bearing inside the workpiece 42 downward.

[0046] Positioning holes 49 are symmetrically arranged on both sides of the bottom tooling 40 to provide docking space for the bottom tooling 40.

[0047] It should be noted that the setting of the docking post 43 and the docking hole 48 makes the position of the workpiece 42 more accurate when it is placed on the surface of the bottom tooling 40, avoiding deviation and affecting the efficiency of the disassembly of the rubber bearing inside the workpiece 42.

[0048] The diameter of the upper fixture 41 is the same as the inner diameter of the workpiece 42, and the inner diameter of the workpiece 42 is smaller than the inner diameter of the bottom fixture 40, so that the rubber bearing can fall into the bottom fixture 40.

[0049] In this embodiment, preferably, the surface of the worktable 1 is provided with two sets of symmetrically arranged positioning components 3, which are used to limit the bottom tooling 40.

[0050] In this embodiment, preferably, the positioning component 3 includes a slide rail 30, which is fixed to the surface of the workbench 1 and has a slider 34 slidably connected to the surface.

[0051] The limiting plate 31 is fixedly connected to one end of the surface of the slide rail 30;

[0052] The limiting block 37 is fixedly connected to the other end of the surface of the slide rail 30;

[0053] The telescopic column 32 is fixedly connected between the limiting plate 31 and the slider 34;

[0054] Spring 33 is sleeved on telescopic column 32;

[0055] Pull handle 35, which is fixed to the surface of slider 34;

[0056] The limiting post 36 is fixedly connected to the middle of one side of the slider 34.

[0057] It should be noted that the telescopic column 32 is a two-section design, with the smaller section sliding within the larger section;

[0058] The setting of the limiting block 37 can effectively prevent the slider 34 from sliding out of the range of the slide rail 30. The limiting plate 31 and the limiting block 37 are set in parallel.

[0059] In this embodiment, preferably, the limiting post 36 slides within the positioning hole 49, and the spring 33 is disposed between the limiting plate 31 and the slider 34.

[0060] In the implementation process, first pull the handle 35. The handle 35 pulls the slider 34 backward along the slide rail 30. The slider 34 moves along the slide rail 30 and squeezes the telescopic column 32 and the spring 33. The bottom fixture 40 is placed in the middle of the two sets of positioning components 3 on the surface of the worktable 1, so that the two positioning holes 49 of the bottom fixture 40 are aligned with the limiting column 36. Release the handle 35. The slider 34 moves along the slide rail 30 into the positioning hole 49 by the counter thrust of the spring 33 to limit the bottom fixture 40.

[0061] Workpiece 42 is docked with docking hole 48 on bottom fixture 40 via docking post 43. Upper fixture 41 is placed on the surface of rubber bearing inside workpiece 42. When downward pressure is applied to the top of upper fixture 41, upper fixture 41 pushes the rubber bearing inside workpiece 42 downward, causing the rubber bearing to be pushed out of workpiece 42 and fall into bottom fixture 40. At the same time, workpiece 42 squeezes the push plate 44 on the surface. Push plate 44 squeezes the connecting post 45 and spring 46. Connecting post 45 moves downward along the middle of positioning plate 47, causing push plate 44 to tighten inside bottom fixture 40 and become flush with the surface of bottom fixture 40. After the applied force is released, push plate 44 moves upward with connecting post 45 by the counter thrust of spring 46 and pushes workpiece 42 on the surface of bottom fixture 40 upward, causing workpiece 42 to quickly detach.

[0062] Example 2

[0063] In this embodiment, preferably, columns 2 are fixedly connected to all four sides of the workbench 1, and a top plate 5 is fixedly connected to the other end of the four columns 2. A hydraulic cylinder 6 is fixedly connected to the middle of the top plate 5, and a pressure plate 7 is fixedly connected to the output end of the hydraulic cylinder 6.

[0064] A housing 8 is fixed to the bottom of the workbench 1. A front door 10 is connected to one side of the housing 8 via a hinge. A mesh protective net 9 is fixed to the other side of the housing 8. An oil pump 11 is placed inside the housing 8.

[0065] It should be noted that the diameter of the pressure plate 7 is larger than that of the upper tooling 41 in order to increase the force-bearing area;

[0066] The oil pump 11 is connected to the oil cylinder 6 via an oil pipe (not shown) to control the extension and retraction of the oil cylinder 6;

[0067] The mesh protective net 9 allows the oil pump 11 inside the housing 8 to dissipate heat and provides protection.

[0068] In this embodiment, preferably, the output end of the hydraulic cylinder 6 is slidably connected to the middle of the top plate 5, and the pressure plate 7 is located directly above the bottom tooling 40.

[0069] During implementation, an oil pump 11 is set up, which pushes the oil cylinder 6 through the oil pipe, causing the oil cylinder 6 to move downward with the pressure plate 7 and apply downward pressure to the surface of the upper tooling 41. When the oil pump 11 is stopped, the oil cylinder 6 moves upward with the pressure plate 7.

[0070] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
