[0043] See also Figure 1 and Figure 2 The present embodiment provides a bearing disassembly device, which includes a grab assembly 100, a clamping component 200 and a pushing component 300. The clamping component 200 is detachably connected to the grab assembly 100. The grab assembly 100 is in contact with the bearing 600 through the clamping component 200. The pushing component 300 is movably connected to the grab assembly 100. The pushing component 300 is used to abut against the central shaft 700. With the help of the pushing action of the pushing component 300, the clamping component 200 drives the bearing 600 to separate from the central shaft 700.

[0044] In this embodiment, the bearing 600 has a proximal end and a distal end, the proximal end is the side of the bearing 600 that is separated from the central axis 700, and the distal end is the side of the bearing 600 that is deeply inserted into the central axis 700, and the clamping component 200 is used to abut against the distal end of the bearing 600, which is equivalent to that the clamping component 200 is connected to the bottom of the bearing 600, the middle part of the pushing component 300 is movably connected to the pulling and grasping component 100, the end of the pushing component 300 acts on the central axis 700, and the pulling and grasping component 100 is used to connect the pushing component 300 and the clamping component 20 0. When the bearing 600 fails, or when the bearing 600 needs to be removed from the central shaft 700, the driving component 300 acts on the central shaft 700, so that the pulling and grasping assembly 100 drives the clamping component 200 to move toward the proximal side of the bearing 600, that is, the clamping component 200 drives the bearing 600 to slide along the central shaft 700, so that the bearing 600 is separated from the central shaft 700. The operation is simple, which can greatly reduce the difficulty of removing the bearing 600 and improve the removal efficiency. The structure is simple and easy to implement.

[0045] Therefore, in this embodiment, the clamping component 200 is used to abut against the bottom of the bearing 600. When the bearing 600 is disassembled, the pushing component 300 abuts against the center axis 700. Through the pushing action of the pushing component 300, the pulling and grasping assembly 100 can drive the clamping component 200 to act on the bottom of the bearing 600, so that the bearing 600 slides out of the center axis 700. The operation is simple and easy to use, which can greatly reduce the difficulty of disassembling the bearing 600 and improve the disassembly efficiency.

[0046] Specifically, see Figure 1 The clamping component 200 includes a clamping plate body 210, a clamping opening 220 and a clamping slot 230. The clamping opening 220 is arranged at the middle position of the clamping plate body 210. The clamping opening 220 facilitates the clamping plate body 210 to be sleeved on the periphery of the central shaft 700. The clamping opening 220 can increase the contact area between the clamping plate body 210 and the bearing 600, so that the clamping plate body 210 and the arc profile of the bearing 600 are matched and connected. At the same time, the clamping opening 220 can facilitate the separation of the clamping plate body 210 from the central shaft 700, that is, it is convenient for the fast loading and unloading of the clamping plate body 210. For example, the clamping opening 220 can be set as a U-shaped groove, that is, the clamping plate body 210 is sleeved on the periphery of the central shaft 700 through the U-shaped groove, so that the clamping body can be matched and connected with the bottom of the bearing 600. Among them, the clamping slot 230 is connected to the clamping body, and the clamping slot 230 is used to be detachably connected with the pulling and grasping assembly 100. When the clamping body is placed at the bottom of the bearing 600, the pulling and grasping part 120 of the pulling and grasping assembly 100 is inserted into the clamping slot 230, that is, the pulling and grasping assembly 100 and the clamping component 200 are connected. When the clamping component 200 and the pulling and grasping assembly 100 need to be disassembled, the pulling and grasping part 120 can be pulled out of the clamping slot 230. The operation is simple and easy to use.

[0047] Specifically, see Figure 1 The grab assembly 100 includes: a grab base 110 and a plurality of grab parts 120 . The plurality of grab parts 120 are movably connected to the grab base 110 . The grab parts 120 are used to clamp the clamping component 200 .

[0048] In this embodiment, the plurality of gripping parts 120 are movably connected to the gripping base 110 , and the plurality of gripping parts 120 grip or release the clamping component 200 by moving on the gripping base 110 , thereby facilitating quick disassembly and assembly of the gripping assembly 100 and the clamping component 200 .

[0049] Specifically, see Figure 1 The grab portion 120 includes: a sliding base 121, a pull rod 122 and a hook 123. The sliding base 121 is slidably connected to the grab base 110, the pull rod 122 is connected to the sliding base 121, and the hook 123 is located at one end of the pull rod 122 away from the sliding base 121. The hook 123 is used to be detachably connected to the clamping component 200.

[0050] In this embodiment, a sliding base 121 is provided at one end of the pull rod 122, and a hook 123 is provided at the other end. The sliding base 121 is used to be slidably connected with the pull grip base 110 to realize the movable connection between the pull grip part 120 and the pull grip base 110, and the hook 123 is used to be inserted into the clamping slot 230 to realize the detachable connection between the pull grip assembly 100 and the clamping part 200. For example, when it is necessary to connect the pull grip assembly 100 with the clamping part 200, the sliding base 121 is pushed to move along the pull grip base 110 close to the bearing 600, so that the pull rod 122 moves closer to the bearing 600 until the hook 123 is inserted into the clamping slot 230, and the docking of the pull grip assembly 100 and the clamping part 200 is completed.

[0051] Specifically, see Figure 2 The grab base 110 includes a cross beam 111 , two ends of the cross beam 111 are respectively connected to the grab parts 120 , and the middle part of the cross beam 111 is connected to the pushing component 300 .

[0052] In this embodiment, the grab base 110 includes: a crossbeam 111, that is, the grab base 110 is made of a crossbeam 111, and the grab parts 120 are connected to the left and right ends of the crossbeam 111 respectively, and a pushing component 300 is arranged in the middle of the crossbeam 111. When the grab assembly 100 needs to be docked with the clamping component 200, the two grab parts 120 are pushed to move toward the middle of the crossbeam 111 to make the grab parts 120 move closer to the clamping component 200 until the hook 123 is inserted into the clamping slot 230, and the docking of the hook 123 and the clamping slot 230 is completed, and the movement of the grab part 120 can be stopped; when the grab assembly 100 and the clamping component 200 need to be disassembled, the grab part 120 is pushed to move outward so that the hook 123 is separated from the clamping slot 230. The operation is simple and easy to use.

[0053] Specifically, see Figure 2 The pushing component 300 includes: a lifting rod body 310, a threaded portion 320 and a screw driving portion 330. The threaded portion 320 is arranged on the lifting rod body 310. The lifting rod body 310 is threadedly connected to the grab base 110 of the grab assembly 100 through the threaded portion 320. The screw driving portion 330 is arranged on a side of the lifting rod body 310 away from the threaded portion 320. The screw driving portion 330 is used to drive the lifting rod body 310 to rotate.

[0054] In this embodiment, the lifting rod body 310 is threadedly connected to the pulling and grabbing assembly 100 through the threaded portion 320. For example, the lifting rod body 310 can be threadedly connected to the middle portion of the beam 111 through the threaded portion 320. The screw drive portion 330 is used to drive the lifting rod body 310 to rotate so that the lifting rod body 310 can be lifted and moved along the beam 111. For example, one end of the lifting rod body 310 away from the screw driving part 330 is in contact with the central axis 700, and the lifting rod body 310 is threadedly connected to the middle part of the beam 111 through the threaded part 320. The two ends of the beam 111 are respectively connected to the clamping component 200 through the pulling and grasping parts 120, and the clamping component 200 is in contact with the bottom of the bearing 600. When the lifting rod body 310 is driven to rotate by the screw driving part 330 so that the lifting rod body 310 acts on the central axis 700, the pulling and grasping part 120 drives the clamping body to move toward the side of the beam 111, and then the clamping body drives the bearing 600 to move outward along the central axis 700, which is equivalent to the pulling and grasping part 120 pulling the bearing 600 out through the clamping body so that the bearing 600 is separated from the central axis 700.

[0055] Optionally, the screw driving portion 330 includes a nut driving portion 331 .

[0056] For example, see Figure 3The screw driving part 330 may include a nut driving part 331, wherein the nut driving part 331 is fixed to the lifting rod body 310. When disassembling the bearing 600, the nut driving part 331 is used to connect with the wrench, and the nut driving part 331 is driven by the wrench to rotate, so as to realize the lifting and lowering movement of the lifting rod body 310 on the beam 111, which saves time and effort and has high disassembly efficiency.

[0057] Optionally, the screw driving portion 330 may include a handle driving portion 332 .

[0058] For example, see Figure 4 The screw driving part 330 may include a handle driving part 332, wherein the handle driving part 332 is fixed to the lifting rod body 310. When the bearing 600 is removed, the handle driving part 332 is used to drive the lifting rod body 310 to rotate to realize the lifting and lowering movement of the lifting rod body 310 on the beam 111. The structure is simple, easy to implement, time-saving and labor-saving, and the disassembly efficiency is high.

[0059] Specifically, see Figure 3 The bearing disassembly device may further include: a fastening component 400 , the fastening component 400 is movably connected to the pulling and grasping assembly 100 , and the fastening component 400 is used to fix the pulling and grasping assembly 100 .

[0060] In this embodiment, the fastening component 400 is connected to the grab assembly 100 and is used to fix the grab assembly 100 so that the grab assembly 100 can remain stable when pulling the clamping component 200, so that the bearing 600 can be smoothly separated from the central shaft 700.

[0061] Specifically, see Figure 3 The fastening component 400 includes: a threaded connection part 410 and an adjusting screw 420. The threaded connection part 410 is connected to the gripping part 120 of the gripping assembly 100. The adjusting screw 420 is threadedly connected to the threaded connection part 410. The adjusting screw 420 is used to adjust the gripping assembly 100 so that the gripping assembly 100 can grip or loosen the clamping component 200.

[0062] In this embodiment, the threaded connection part 410 is connected to the gripping part 120, and the adjusting screw 420 is threadedly connected to the threaded connection part 410. By rotating the adjusting screw 420, the distance between the two gripping parts 120 can be adjusted to achieve the clamping of the two gripping parts 120 on the clamping component 200. For example, the two ends of the crossbeam 111 are respectively connected to the gripping parts 120, and the middle of the gripping parts 120 is provided with a threaded connection part 410. The adjusting screw 420 passes through the threaded connection parts 410 on the two gripping parts 120 in sequence, and the adjusting screw 420 is threadedly connected to the threaded connection part 410. By rotating the adjusting screw 420, the two gripping parts 120 are brought closer to or separated from each other. When the bearing 600 needs to be removed, the adjusting screw 420 can be rotated so that the two grabbing parts 120 are clamped on the clamping component 200 to achieve a stable connection between the clamping component 200 and the bearing 600, and then the pushing component 300 is rotated so that the clamping component 200 drives the bearing 600 to disengage from the central axis 700.

[0063] Specifically, see Figure 5 The bearing disassembly device also includes: an electric driving component 500, which is drivingly connected to the pushing component 300, and the electric driving component 500 is used to drive the pushing component 300 to abut against the central axis 700, so that the clamping component 200 drives the bearing 600 to separate from the central axis 700.

[0064] In this embodiment, the electric drive component 500 can be driven and connected to the pushing component 300, that is, the electric drive component 500 can push the component 300 to move, providing a power source for the bearing 600 to separate from the central axis 700, saving time and effort and increasing disassembly efficiency.

[0065] For example, the electric drive component 500 may include an electric wrench, that is, the electric drive component 500 uses an electric wrench to drive the pushing component 300 to move up and down. The pushing component 300 may include: a lifting rod body 310, a threaded portion 320 and a screw driving portion 330. The electric wrench can be connected to the screw driving portion 330. The screw driving portion 330 can be driven by the electric wrench to rotate so that the lifting rod body 310 can be lifted and moved on the beam 111, thereby realizing the clamping component 200 driving the bearing 600 to disengage from the central axis 700, which saves time and effort, has high disassembly efficiency, and can greatly reduce the difficulty of disassembling the bearing 600.

[0066] For example, the electric drive component 500 may include a cylinder, that is, the electric drive component 500 is driven by the cylinder to enable the pushing component 300 to move up and down. For example, the pushing component 300 may include a lifting rod body 310, and the lifting rod body 310 may be slidably connected to the beam 111. One end of the lifting rod body 310 is driven by the cylinder, and the other end of the lifting rod body 310 may be abutted against the central axis 700. The lifting rod body 310 is driven by the cylinder to move up and down along the beam 111, so as to realize the clamping component 200 driving the bearing 600 to disengage from the central axis 700, which saves time and effort, has high disassembly efficiency, and can greatly reduce the difficulty of disassembling the bearing 600.

[0067] In summary, the present application discloses a bearing disassembly device, which includes a grab assembly, a clamping component and a pushing component. The clamping component and the grab assembly are detachably connected. The grab assembly abuts against the bearing through the clamping component. The pushing component is movably connected to the grab assembly. The pushing component is used to abut against the central axis. With the help of the pushing action of the pushing component, the clamping component drives the bearing to separate from the central axis. In the present application, the clamping component is used to abut against the bottom of the bearing. When disassembling the bearing, the pushing component abuts against the central axis. Through the pushing action of the pushing component, the grab assembly can drive the clamping component to act on the bottom of the bearing, so that the bearing slides out of the central axis. The operation is simple and easy to use. It can greatly reduce the difficulty of disassembling the bearing and improve the disassembly efficiency.
