[0044] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0045] like Figure 1 , 2 As shown in Figure 3, the utility model provides a train wheel bearing disassembly device, including a moving component 1, a lifting component 2, a bracket 3 and two bearing disassembly components 4, the lifting component 2 is fixed to the moving component 1, and the lifting component 2 has a lifting platform 21 that can be lifted and lowered relative to the moving component 1; the bracket 3 is connected to the lifting platform 21; the two bearing disassembly components 4 are symmetrically arranged on both sides of the bracket 3.

[0046] Specifically, the train wheel bearing disassembly device is moved to the position where the train wheel bearing needs to be disassembled by moving the moving component 1; by controlling the lifting and lowering of the lifting platform 21 in the lifting component 2, the bearing disassembly component 4 corresponds to the height of the bearing of the train wheel, and the two bearing disassembly components 4 clamp the two bearings of the train wheel. After accommodating them, the bearings are removed from the wheel axle through the bearing disassembly components 4, thereby realizing the disassembly of the bearings. The train wheel bearing disassembly device can be moved to the next position to disassemble the bearings.

[0047] In the utility model, the moving component 1 can drive the train wheel bearing disassembly device, and can disassemble the bearings on the train wheels at different positions; by setting the lifting component 2, the lifting platform 21 of the lifting component 2 can drive the bracket 3 and the bearing disassembly component 4 to lift and lower, so that the bearing disassembly component 4 can correspond to train wheels of different diameters and can disassemble the bearings on train wheels of different diameters.

[0048] It should be understood that the moving component 1 can be a platform with wheels and a rail trolley, etc.; the lifting component 2 can be a lifting component 2 that can drive the lifting platform 21 to rise and fall by hydraulic, electric or manual means, and can also drive the lifting platform 21 to rise and fall by a hydraulically driven fork arm.

[0049] It should be understood that the support 3 can be a gantry, a beam, a frame formed by splicing various profiles, etc.

[0050] It should be understood that the number of movable components 1 and lifting components 2 can be one, two, three, etc. Specifically, in one embodiment, the number of movable components 1 and lifting components 2 is two, and the two movable components 1 are arranged on both sides of the bracket 3, and the two lifting components 2 are respectively arranged on the two movable components 1.

[0051] like Figure 2 As shown, in one embodiment, the bracket 3 is formed with a bearing receiving groove 3a; the train wheel bearing disassembly device also includes a manipulator 5, which is connected to the bracket 3 and is used to transfer the bearing disassembled by the bearing disassembly assembly 4 to the bearing receiving groove 3a.

[0052] Specifically, when the bearing is disassembled, the manipulator 5 is started to grab the disassembled bearing, and the manipulator 5 moves the grabbed bearing to the top of the bearing receiving groove 3a, and then puts the bearing into the bearing receiving groove 3a. By providing the bearing receiving groove 3a and the manipulator 5, the disassembled bearing can be temporarily stored, and the disassembled bearing does not need to be immediately transported to a designated storage location, which can reduce the number of times the bearing is transported.

[0053] It should be understood that the manipulator 5 can be driven electrically, hydraulically or pneumatically, has multiple degrees of freedom, and can perform actions such as grasping, moving and placing bearings.

[0054] like Figure 2 As shown, in one embodiment, bearing accommodating grooves 3 a are provided on both sides of the bracket 3 .

[0055] By providing bearing receiving grooves 3a on both sides of the bracket 3, the storage capacity of the device is increased, and more disassembled bearings can be accommodated. Since bearings can be stored on both sides of the bracket 3, the manipulator 5 can switch freely between the two sides, thereby improving the efficiency of the disassembly work.

[0056] like Figure 2 As shown, in one embodiment, manipulators 5 are provided on both sides of the bracket 3 .

[0057] By arranging the manipulators 5 on both sides of the bracket 3, the device can transfer the bearings on both sides at the same time, which greatly improves the working efficiency. The manipulators 5 on both sides can balance the load of the bracket 3 and improve the stability of the device.

[0058] like Figure 2 As shown, in one embodiment, the robot 5 is a six-axis robot arm.

[0059] The six-axis robotic arm has higher degrees of freedom and flexibility, enabling high-precision operations and ensuring accurate grasping, moving and placement of bearings.

[0060] It should be understood that a clamping claw can be provided at the end of the movable end of the six-axis robot arm to clamp the removed bearing through the clamping claw, and an electromagnetic suction cup can also be provided at the movable end of the six-axis robot arm to absorb the removed bearing through the electromagnetic suction cup.

[0061] like Figure 3 As shown, in one embodiment, the mobile component 1 is an AGV vehicle.

[0062] The AGV is a type of handling equipment that can autonomously navigate, locate and move. It can move autonomously in factories, warehouses and other places according to settings.

[0063] In one embodiment, the wheels of the AGV vehicle are Mecanum wheels.

[0064] By adopting Mecanum wheels as the wheels of the AGV trolley, the AGV trolley can move in any direction, and can drive the bracket 3 and the bearing removal assembly 4 to move in any direction, providing flexibility in the movement of the bearing removal assembly 4.

[0065] like Figure 2 As shown, in one of the embodiments, the bearing removal assembly 4 includes a sliding seat 41, a pulling member 42 and a first linear drive member 43. The sliding seat 41 is slidably connected to the bracket 3, and the sliding directions of the sliding seats 41 in the two bearing removal assemblies 4 are the same. The pulling member 42 is connected to the sliding seat 41, and the pulling member 42 can abut against one end of the bearing away from the sliding seat 41. The first linear drive member 43 has a fixed end and a telescopic end. The fixed end of the first linear drive member 43 is connected to the sliding seat 41, and the telescopic end can abut against the end of the axle of the train wheel when the pulling member 42 abuts against the bearing, so as to drive the pulling member 42 to remove the bearing from the axle through the telescopic movement of the first linear drive member 43.

[0066] When it is necessary to remove the bearing on the train wheel through the bearing removal assembly 4, the lifting assembly 2 and the lifting bracket 3 are used, and the bracket 3 drives the bearing removal assembly 4 to move, so that the pulling member 42 corresponds to the bearing of the train wheel, and the pulling member 42 abuts against the end of the bearing away from the sliding seat 41, and then the first linear drive member 43 is started, and the telescopic end of the first linear drive member 43 abuts against the axle of the train wheel. The continuous extension of the telescopic end of the first linear drive member 43 can push the sliding seat 41 to slide in the direction away from the bearing, and the sliding seat 41 drives the pulling member 42 to slide, so as to remove the bearing from the axle of the train through the pulling member 42, thereby realizing the removal of the bearing.

[0067] It should be understood that the sliding seat 41 can be slidably connected to the bracket 3 through a sliding rail, a sliding groove, a sliding block, etc.

[0068] It should be understood that the first linear drive member 43 may be an electric push rod, a hydraulic cylinder, a pneumatic cylinder, or the like.

[0069] It should be understood that the pulling member 42 can be a hook, a clamp or a component of other shapes, which is used to grab the edge or inner ring of the bearing so as to pull the bearing out when the sliding seat 41 moves.

[0070] like Figure 2 and Figure 4As shown, in one embodiment, the bearing removal assembly 4 further includes a second linear drive member 44, and the second linear drive member 44 is respectively connected to the sliding seat 41 and the bracket 3.

[0071] By providing a second linear drive member 44, the second linear drive member 44 can drive the sliding seat 41, the first linear drive member 43 and the pulling member 42 to slide, so as to adjust the distance of the pulling member 42 relative to the bearing along the axial direction of the axle;

[0072] When the bearing removal assembly 4 removes the bearing, the second linear drive 44 is started, and the second linear drive 44 can drive the sliding seat 41 to slide away from the bearing, so that the sliding seat 41 drives the pulling member 42 to slide, and the pulling member 42 drives the bearing to separate from the axle of the train wheel.

[0073] It should be understood that the second linear drive member 44 may be an electric push rod, a hydraulic cylinder, a pneumatic cylinder, or the like.

[0074] like Figure 4 As shown, in one embodiment, the pulling member 42 includes a pulling plate 421 and a connecting portion 422, the pulling plate 421 is formed with an arc groove 421a, the pulling plate 421 can be sleeved on the bearing through the arc groove 421a, a blocking bar 423 is formed on the side of the pulling plate 421 away from the sliding seat 41, the blocking bar 423 can abut against the side of the bearing away from the sliding seat 41; the connecting portion 422 connects the pulling plate 421 and the sliding seat 41.

[0075] The pull plate 421 is formed with an arc groove 421a, and the pull plate 421 can be sleeved on the bearing through the arc groove 421a. The shape of the arc groove 421a matches the shape of the bearing, so that the pull plate 421 can fit tightly on the outer ring of the bearing; a stop bar 423 is formed on the side of the pull plate 421 away from the sliding seat 41, and the stop bar 423 can abut against the side of the bearing away from the sliding seat 41. The function of the stop bar 423 is to block the bearing during the disassembly process to prevent the bearing from slipping off the pull plate 421; the connecting portion 422 connects the pull plate 421 and the sliding seat 41 to fix the pull plate 421 on the sliding seat 41. The connecting portion 422 can be a bolt, a pin or other form of connecting part; when the bearing needs to be removed, first move the sliding seat 41 to a suitable position so that the arc groove 421a of the pull plate 421 covers the bearing, and make the blocking bar 423 abut the side of the bearing away from the sliding seat 41; then, the telescopic end of the first linear drive member 43 extends out, driving the sliding seat 41 to move away from the bearing, and pulling the bearing off the shaft through the pull plate 421; after completing the disassembly, move the sliding seat 41 back to its original position and prepare for the next disassembly.

[0076] It should be understood that the arc-shaped groove 421a of the pull plate 421 can be open at the bottom, can be open at the top, can be open at the side, etc.

[0077] It should be understood that the connection part 422 may be a long bar, a block, a strip structure, etc. connected to the pull plate 421 , and the number of the connection part 422 may be one or more.

[0078] Taking the bottom opening of the slide groove as an example, through the lifting component 2, the pull plate 421 is mounted on the bearing from high to low, and the blocking bar 423 abuts against the end of the bearing away from the sliding seat 41, thereby realizing the abutment between the pull plate 421 and the bearing. At this time, when the first linear drive member 43 drives the sliding seat 41 to slide in the direction away from the bearing, the blocking bar 423 can drive the bearing to fall off the wheel axle.

[0079] like Figure 4 As shown, in one of the embodiments, the telescopic end sleeve of the first linear drive member 43 is provided with a nylon sleeve 45.

[0080] The nylon sleeve 45 is an engineering plastic with good wear resistance, corrosion resistance and self-lubricating properties. The nylon sleeve 45 is sleeved on the telescopic end of the second linear drive member 44 to reduce the friction and wear between the telescopic end and the bearing and increase the service life.

[0081] The process of disassembling the bearing of the utility model is as follows: the moving assembly 1 drives the entire device to move to the position where the train wheel bearing needs to be disassembled;

[0082] The lifting assembly 2 adjusts the height of the lifting platform 21 so that the bracket 3 reaches a suitable height, so that the telescopic end of the first linear drive member 43 is aligned with the axle of the train;

[0083] The second linear drive member 44 drives the sliding seat 41, the first linear drive member 43 and the pull plate 421 to move along the axis of the axle of the train wheel, so that the stop bar 423 moves to the side of the bearing away from the sliding seat 41;

[0084] Then the lifting platform 21 is lowered, and the lifting platform 21 drives the bracket 3, the sliding seat 41 and the pull plate 421 to move, so that the pull plate 421 is sleeved on the bearing, and the stop bar 423 abuts against the side of the bearing away from the sliding seat 41;

[0085] The telescopic end of the first linear driving member 43 is extended so that the telescopic end of the first linear driving member 43 abuts against one end of the axle close to the sliding seat 41;

[0086] The telescopic end of the first linear drive member 43 continues to extend, and together with the second linear drive member 44, drives the sliding seat 41 to slide in a direction away from the bearing, and the sliding seat 41 drives the pulling member 42 to move, and the bearing is pulled out of the axle through the pulling member 42, and the bearing is gradually sleeved on the telescopic end of the first linear drive member 43 when it is separated from the axle;

[0087] The manipulator 5 transfers the disassembled bearing to the bearing receiving grooves 3a on both sides of the bracket 3;

[0088] Repeat the above steps until all bearings that need to be disassembled are disassembled and placed in the bearing receiving groove 3a.

[0089] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
