DETAILED DESCRIPTION

[0016] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0017] Embodiments of the present utility model: Figure 1 and Figure 2 As shown, a special disassembly tool for a sleeve gear bearing of a packaging machine includes a support plate 1, a vertical plate 2 is fixedly provided in the middle of the support plate 1, a first threaded hole 3 is opened on the vertical plate 2, a threaded rod 4 is threadedly connected with the first threaded hole 3 on the vertical plate 2, a sleeve gear limiting structure is provided at one end of the support plate 1, and a threaded rod driving structure is provided at the other end of the support plate 1.

[0018] The sleeve gear limiting structure is used to clamp the sleeve gear, and push the sleeve 24 of the sleeve gear through the end of the threaded rod 4, so that the sleeve 24 is separated from the bearing 25, thereby realizing the removal of the bearing 25. The threaded rod driving structure is used to provide power for the rotation of the threaded rod.

[0019] In a specific embodiment, the vertical plate 2 is arranged vertically, and a horizontal mounting plate 5 is formed at the bottom of the vertical plate 2. A plurality of through holes are opened on the horizontal mounting plate 5, and a threaded hole is opened on the support plate 1. The first bolt 6 passes through the through hole on the mounting plate 5 and is threadedly connected with the threaded hole on the support plate 1, so that the mounting plate 5 is fixed on the support plate 1.

[0020] In this embodiment, the vertical plate 2 and the mounting plate 5 are an integrally formed structure, and can be quickly replaced by fixing them with the first bolt 6. When the first threaded hole 3 becomes larger or the teeth are damaged due to long-term use, the problem can be solved by quickly replacing the vertical plate 2 and the mounting plate 5.

[0021] Furthermore, the sleeve gear limiting structure includes an end plate 7 and a clamping plate 8. The lower end of the end plate 7 is fixedly connected to the end of the support plate 1 by a second bolt 9. A first U-shaped groove 10 is opened in the middle position of the end plate 7. The opening of the first U-shaped groove 10 is located at the top of the end plate 7. Slide grooves 11 are formed on both side edges of the first U-shaped groove 10. Both side edges of the clamping plate 8 are plugged into and slidably connected with the slide grooves 11. A second U-shaped groove 12 is opened in the middle of the clamping plate 8. The opening end of the second U-shaped groove 12 is located at the bottom of the clamping plate 8.

[0022] The end plate 7 is arranged vertically and is parallel to the vertical plate 2. The first U-shaped groove 10 is used to install the clamping plate 8, so the opening width of the first U-shaped groove 10 should be larger than the outer diameter of the sleeve gear. This embodiment provides clamping plates 8 of various specifications. The widths of the second U-shaped grooves 12 on clamping plates 8 of different specifications are different to suit the disassembly of bearings of sleeve gears of different sizes.

[0023] Preferably, a mounting groove 13 is formed at the lower end of the side of the end plate 7 facing the support plate 1, and one end of the support plate 1 is plugged and connected to the mounting groove 13. Since the end plate 7 is subjected to a large force when the bearing 25 is disassembled, the installation groove 13 is provided to make the connection between the end plate 7 and the support plate 1 more firmly, so that the end plate 7 is not easy to be skewed, and the service life is improved.

[0024] Furthermore, the threaded rod driving structure includes a slide rail 14, a slider 15, a slide plate 16, a motor 17 and a reducer 18. Two parallel slide rails 14 are fixed on the top surface of the support plate 1, and sliders 15 are slidably mounted on the two slide rails 14. The two sliders 15 are fixedly connected to the bottom surface of the slide plate 16. The reducer 18 and the motor 17 are both fixedly mounted on the top surface of the slide plate 16 by bolts. The output shaft of the motor 17 is connected to the input end of the reducer 18, and the output end of the reducer is fixedly connected to one end of the threaded rod 4 through a coupling 27.

[0025] When the motor 17 is working, the speed is reduced and the torque is increased through the reducer 18, and the power is output through the threaded rod 4. The threaded rod 4 is threadedly matched with the vertical plate 2. Since the vertical plate 2 is fixed, the threaded rod 4 is displaced relative to the vertical plate 2, and the end of the threaded rod 4 is supported by the end of the sleeve 24 of the sleeve gear, so that the sleeve 24 is separated from the bearing 25.

[0026] It should be noted that, in addition to the above-mentioned electric drive solution, a manual drive method can also be used, for example, a handle (not shown in the figure) perpendicular to the end of the threaded rod 4 can be welded, and the handle can be rotated by hand to rotate the threaded rod 4. The manual method has lower working efficiency than the electric method and is laborious, but it is more efficient than the method of knocking the transmission pin shaft.

[0027] Furthermore, a columnar end 19 is formed at one end of the threaded rod 4 away from the reducer 18 , and a baffle 20 is formed on the columnar end 19 .

[0028] The diameter of the columnar end 19 is equal to the aperture of the sleeve 24. When working, the columnar end 19 is inserted into the sleeve 24. The diameter of the baffle 20 should be smaller than the inner aperture of the bearing 25. The arrangement of the columnar end 19 and the baffle 20 can effectively protect the sleeve 24 and prevent the end of the sleeve 24 from being damaged.

[0029] Furthermore, a circular push plate 21 is further included, and a mounting hole 22 is formed at the center of the circular push plate 21, and the diameter of the mounting hole 22 is equal to the diameter of the columnar end 19. The circular push plate 21 is used when the bearing 25 is installed, and a circular avoidance groove 23 is formed on the surface of the circular push plate 21 facing the bearing 25.

[0030] The working principle of the utility model is as follows: when disassembling the bearing 25 on the sleeve gear of the packaging machine, first remove the card plate 8, clamp the second U-shaped groove 12 on the card plate 8 on the sleeve 24, and then install the card plate 8 into the first U-shaped groove 10 on the end plate 7, and then start the motor 17. When the motor 17 works, it drives the threaded rod 4 to rotate through the reducer 18. Since the vertical plate 2 is fixed on the support plate 1 and does not move, when the threaded rod 4 rotates, the threaded rod 4 is displaced relative to the vertical plate 2. When the end of the threaded rod 4 is close to the sleeve gear of the packaging machine, the threaded rod 4 is displaced relative to the vertical plate 2. At this time, the motor 17, the reducer 18 and the slide plate 16 move synchronously, and the slider 15 slides on the slide rail 14. The staff lifts the sleeve 24 of the sleeve gear of the packaging machine by hand in advance to make the sleeve 24 coaxial with the threaded rod 4. As the threaded rod 4 moves, the columnar end 19 is inserted into the sleeve 24, and the baffle 20 abuts against the end face of the sleeve 24. At this time, the bearing 25 abuts against the clamping plate 8. As the threaded rod 4 continues to move, the sleeve 24 is separated from the bearing 25, and the motor 17 is controlled to rotate in the opposite direction, and the threaded rod 4 retreats to the initial position.

[0031] When installing the bearing 25, it is necessary to place the gear 26 on the sleeve 24 between the clamping plate 8 and the vertical plate 2, and then install the circular push plate 21 on the columnar end 19. After starting the motor 17, the circular push plate 21 is driven by the threaded rod 4 to approach the sleeve 24, and the bearing to be installed is placed on the end of the sleeve 24. When the circular push plate 21 is against the bearing 25, the gear 26 is in contact with the clamping plate 8. At this time, the sleeve 24 and the bearing 25 are coaxial with the threaded rod 4. As the threaded rod 4 continues to advance, the bearing 25 is pressed onto the sleeve 24 through the circular push plate 21.

[0032] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
