[0030] like Figure 1As shown, an embodiment of the present application provides a bearing outer ring disassembly tool 100, which is used to disassemble the bearing outer ring 200 that remains in the bearing seat 300 after the bearing is damaged. In this embodiment, the bearing seat 300 can be a bearing seat 300 in a cigarette making device, such as the bearing seat 300 in the cigarette pushing and discharging assembly of a YB65 type box packaging machine. The bearing seat 300 in this embodiment can be a flat-bottomed bowl shape. When disassembling a bearing seat 300 of this shape, the space between the bearing seat 300 and the bearing outer ring 200 is narrow, and tools such as screwdrivers and copper rods are difficult to exert force, and it is difficult to achieve effective knocking. It can be understood that the bearing outer ring disassembly tool 100 provided in the embodiment of the present application can also be used to disassemble the bearing outer ring 200 in other types of bearing seats 300. Furthermore, the bearing in this embodiment can be a ball bearing, combined with Figure 2 An annular guide groove 201 for guiding the balls of the bearing is circumferentially provided on the inner side of the bearing outer ring 200 . The bearing outer ring disassembly tool 100 provided in the embodiment of the present application is engaged with the annular guide groove 201 to facilitate the application of force to the bearing outer ring 200 .
[0031] like Figure 3 and Figure 4 As shown, the bearing outer ring disassembly tool 100 includes a bracket 1, a clamping member 2 and a ejector 3, please refer to Figure 5 The bracket 1 is a columnar structure, and a hollow space with an opening is formed inside the bracket 1. The hollow space is used to accommodate the ejector 3. The hollow space extends along the axial direction of the bracket 1. The opening is formed at the end of the bracket 1.

Please refer to Figure 6The clamping member 2 includes a sliding portion 22 and a clamping portion 23 which are fixedly connected. The sliding portion 22 is slidably arranged in the through groove 11. The sliding portion 22 can slide in the through groove 11 along the radial direction of the bracket 1 to drive the clamping member 2 to switch between the storage position and the deployment position. When the clamping member 2 switches between the storage position and the deployment position, the moving direction of the clamping member 2 is the radial direction of the bracket 1. When the clamping member 2 is in the storage position, the free end of the sliding portion 22 which is not connected to the clamping portion 23 is located in the hollow space, so that the ejection portion 31 contacts and interacts with the free end. The distance between the distal end of the clamping portion 23 and the axis of the bracket 1 is less than the radius of the inner side of the bearing outer ring 200, so that the clamping portion 23 in the storage position can be placed in the bearing outer ring 200. In this embodiment, the radius of the inner side of the bearing outer ring 200 can be the inner ring of the bearing outer ring 200 without the annular guide groove 201. The distal end of the clamping part 23 can be the position on the clamping part 23 that is farthest from the axis of the bracket 1; when the clamping part 2 is in the unfolded position, the distance between the distal end of the clamping part 23 and the axis of the bracket 1 is greater than the radius of the inner side of the bearing outer ring 200 and less than or equal to the radius of the annular guide groove 201, so that the clamping part 2 can be clamped into the annular guide groove 201 to achieve clamping with the bearing outer ring 200. In this embodiment, the radius of the annular guide groove 201 can be the radius of the circle where the bottom of the annular guide groove 201 is located. Please refer to Figure 7 The ejector 3 is formed with an ejector portion 31 whose size is smaller than the hollow space. The ejector portion 31 can enter the hollow space through the opening and can move in the axial direction of the bracket 1 in the hollow space. The ejector portion 31 can move to the free end in the hollow space so that the ejector portion 31 contacts and interacts with the free end, wherein the free end and / or the end 311 of the ejector portion forms an inclined surface, so that the sliding portion 22 is driven to slide radially along the bracket 1 by the axial movement of the end 311 of the ejector portion along the bracket 1. In this embodiment, the free end can form an inclined surface, the end 311 of the ejector portion can form an inclined surface, or the free end and the end 311 of the ejector portion can form mutually matching inclined surfaces.
[0032] The bearing outer ring disassembly tool 100 provided in the embodiment of the present application ejects the clamping member 2 to the unfolded position through the ejection member 3, at which time the clamping member 2 can be clamped into the annular guide groove 201 of the bearing outer ring 200, so that the bearing outer ring 200 can be forcefully applied to the bearing outer ring 200 through the bearing outer ring disassembly tool 100 to remove the remaining bearing outer ring 200 in the bearing seat 300. When the bearing outer ring disassembly tool 100 provided in the embodiment of the present application is used to disassemble the bearing outer ring 200 in the bearing seat 300, the disassembly efficiency is high, no knocking is required, the damage to the bearing seat 300 is reduced, the spare parts of the bearing seat are saved, and the safety hazards are reduced.

In this embodiment, by providing multiple clamping members 2, the outer ring 200 of the bearing can be evenly stressed and easier to disassemble. The number of the through slots 11 corresponds to the number of the clamping members 2, so that the through slots can better limit the position of the clamping members 2. In some embodiments, the number of the clamping members 2 is two, and the two clamping members 2 are the same, and the two clamping members 2 can both be semicircular.
[0034] like Figure 5 and Figure 6 As shown, in some embodiments, the position 12 where the bracket is provided with the clamping member is cylindrical; the clamping member 2 also includes a clamping member body 21. When the multiple clamping members 2 are in the storage position, the clamping member bodies 21 of the multiple clamping members 2 are spliced into a complete cylindrical shape concentrically sleeved on the bracket 1. In this embodiment, when the clamping member 2 is provided on the bracket 1, the inner cylindrical surface of the clamping member body 21 contacts the outer cylindrical surface of the bracket 1; the clamping portion 23 of each clamping member 2 is constructed as a convex rib protruding outward along the radial direction of the clamping member body 21 in the circumferential direction of the clamping member body 21, and the shape and size of the convex rib correspond to the annular guide groove 201; the sliding portion 22 of each clamping member 2 is constructed as a straight plate protruding inward along the radial direction of the clamping member body 21 on the clamping member body 21, and the size of the straight plate corresponds to the through groove 11. In this embodiment, the bracket 1 and the clamping member 2 can better match the shape of the inner ring of the bearing to achieve a more stable clamping of the inner ring of the bearing.
[0035] In some embodiments, a circular baffle 13 is concentrically arranged at the end of the bracket 1 where no opening is formed, and the diameter of the circular baffle 13 is larger than the diameter of the bracket 1, so that the outer edge of the circular baffle 13 protrudes from the bracket 1, one end of the clamping member 2 abuts against the outer edge of the circular baffle 13, and the through groove 11 is opened at the position connected to the circular baffle 13 on the side of the bracket 1, and part of the groove wall of the through groove 11 is formed by the circular baffle 13. In this embodiment, the circular baffle 13 can limit the clamping member 2 to prevent the clamping member 2 from being skewed when subjected to the axial force of the ejection member 3, thereby affecting the clamping effect.
[0036] like Figure 5 As shown, in some embodiments, the bracket is provided with a first external thread 14 on one side of the position 12 where the clamp is provided, away from the circular baffle 13, Figure 6 The radial dimension of the end of the clip body 21 away from the circular baffle 13 gradually decreases; Figure 8The bearing outer ring disassembly tool 100 also includes a clamping nut 4, which is matched with the first external thread 14 through the first internal thread set on the inner side; the clamping nut 4 forms a bell mouth 401 with a gradually increasing radial size at one end close to the clip 2, and the bell mouth 401 cooperates with the end of the clip body 21 away from the circular baffle 13, so that the clamping nut 4 can be rotated to approach the clip 2 and clamp the clip 2 in the storage position. When tightening the clamping nut 4, the inclined surface at the bell mouth 401 of the clamping nut 4 and the inclined surface at the end of the clip body 21 away from the circular baffle 13 can cooperate with each other to provide a radially inward clamping force on the clip 2.
[0037] In some embodiments, a second internal thread is provided inside the bracket 1; Figure 7 The ejection part 31 is rod-shaped and is provided with a second external thread 32 that cooperates with the second internal thread. In this embodiment, the ejection part 31 can be screwed in and out of the hollow space by rotating the ejection part 31. The threaded cooperation can facilitate the ejection part 31 to stay in a predetermined position, and the ejection part 31 can provide a greater ejection force for the clamping part 2 by screwing in. Figure 6 and Figure 7 In some embodiments, the end portion 311 of the ejection portion is in the shape of a truncated cone, and the free end forms a curved inclined surface matching the inclination angle of the truncated cone.
[0038] In some embodiments, the ejector 3 further includes a first polygonal column 15, the ejector portion 31 is connected to the first polygonal column 15, and a first screw hole is provided at one end of the first polygonal column 15 away from the ejector portion 31. In this embodiment, a rotational torque can be applied to the ejector portion 31 through the first polygonal column 15. For example, the first polygonal column 15 can be a hexagonal column so that a rotational torque can be applied to the ejector 3 through a hexagonal wrench; in addition, in this embodiment, the first screw hole can be conveniently matched with an external tool (such as a pull hammer), so that the bearing outer ring 200 can be easily disassembled by applying force through the external tool.
[0039] In some embodiments, the bearing outer ring disassembly tool 100 further includes a bolt 5, on which a third external thread 51 is formed, and the third external thread 51 is used to cooperate with the second screw hole of the bearing seat 300 located on the axis of the bearing seat 300; the end of the bolt 5 provided with the third external thread 51 is also provided with a cylindrical positioning column 52, and the circular baffle 13 is also provided with a circular positioning hole 131 for cooperating with the positioning column 52.
