[0021] Embodiment 1
[0022] Combined with Figure 1 , Figure 2 , Figure 3 and Figure 4 , a bearing seat disassembly auxiliary tool comprises a mounting seat 1, and outer push rods 2 are respectively connected on both sides of the mounting seat 1, and the outer push rod 2 is an L-shaped structure. Slide grooves 9 are respectively connected on both sides of the mounting seat 1, and the slide grooves 9 are slidably matched with one end of the outer push rod 2. The mounting seat 1 is connected with a first threaded hole 10 in the direction perpendicular to the slide groove 9, and the first threaded hole 10 is provided with a locking bolt 11 through a threaded connection. The locking bolt 11 can limit the outer push rod 2, and an inner push rod 3 is connected through a thread in the middle of the mounting seat 1. A first hand wheel 4 is connected to the top of the inner push rod 3, and a fixed seat 5 is rotatably connected at the bottom of the inner push rod 3. The bottom end of the inner push rod 3 penetrates the fixed seat 5, and the fixed seat 5 is evenly hinged with outer hooks 6 in the circumferential direction, and an inner hook 7 is hinged in the middle of the outer hook 6. The hook at the bottom end of the outer hook 6 is in opposite directions to the hook at the bottom end of the inner hook 7. A lifting plate 8 is sleeved on the inner push rod 3, and the lifting plate 8 can drive the outer hook 6 to rise and fall. The lifting plate 8 is circumferentially connected with a hinge seat, and the lifting plate 8 is hinged with a first hinge rod 12 through the hinge seat. The other end of the first hinge rod 12 is hinged with a second hinge rod 13, and the other end of the second hinge rod 13 is hinged to the middle part of the outer hook 6. A lifting drive assembly is connected to the lifting plate 8, and the lifting drive assembly includes a driving cylinder 14 rotatably connected to the top of the inner push rod 3, and the top of the driving cylinder 14 is connected to a second hand wheel 15. The driving cylinder 14 is connected to a connecting plate 16 through a threaded connection, and guide rods 17 are respectively connected on both sides of the connecting plate 16. The other end of the guide rod 17 slides through the mounting seat 1 and is connected to the lifting plate 8 at the other end.
[0023] The outer bearing and the inner bearing can be disassembled by coordinating the mounting seat 1, the inner push rod 3, the first hand wheel 4, the fixing seat 5, the inner hook 7, the outer hook 6, the lifting plate 8, and the lifting drive assembly, thereby avoiding damage to the bearings caused by hard knocking and disassembly, and improving the applicability of the device.
[0024] The specific usage is as follows:
[0025] When the outer bearing needs to be disassembled, the bottom end of the inner push rod 3 is abutted against the mounting shaft of the outer bearing to provide a fulcrum for the disassembly operation, so that the hook of the inner hook 7 hooks the circumference of the outer bearing, and then the second hand wheel 15 is driven. The second hand wheel 15 drives the connecting plate 16 through the threaded cooperation of the driving cylinder 14 and the connecting plate 16. The connecting plate 16 drives the lifting plate 8 to move up and down through the guide rod 17. The lifting plate 8 drives the outer hook 6 up and down through the first hinge rod 12 and the second hinge rod 13. The outer hook 6 drives the inner hook 7 to drive the outer bearing to separate from its internal mounting shaft to complete the disassembly;
[0026] When the inner bearing needs to be removed, first adjust the outer push rod 2 so that it is in contact with both sides of the shaft seat of the inner bearing to provide a fulcrum for the disassembly operation, and then drive the second hand wheel 15. The second hand wheel 15 drives the connecting plate 16 through the threaded cooperation of the driving cylinder 14 and the connecting plate 16. The connecting plate 16 drives the lifting plate 8 to move up and down through the guide rod 17. The lifting plate 8 drives the outer hook 6 up and down through the first hinge rod 12 and the second hinge rod 13, so that the outer hook 6 can cooperate with inner bearings of different diameters. Finally, by turning the first hand wheel 4, the first hand wheel 4 drives the inner push rod 3 to rotate. The inner push rod 3 drives the driving cylinder 14 to drive the outer hook 6 at the bottom up and down through the threaded connection with the mounting seat 1, thereby realizing the disassembly of the inner bearing and the shaft seat.
