[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0029] In some embodiments, please refer to the accompanying drawings. Figures 1-6 An adaptive adjustable bearing assembly device includes a rotor loading pipe 10, a rotor unloading pipe 11, a support column 12, a support platform 13, and a bearing unloading pipe 14.

[0030] It also includes a rotor dwelling conveyor mechanism 2 and a bearing automatic installation mechanism 3. The rotor feeding pipe 10 and the rotor discharging pipe 11 are respectively set on the front and rear sides of the support column 12. The two rotor dwelling conveyor mechanisms 2 are respectively connected above the two support columns 12. The two support platforms 13 are respectively located on the left and right sides of the support column 12. The upper end of each support platform 13 is fixedly connected to the bearing discharging pipe 14. The bearing automatic installation mechanism 3 is set between the support platform 13 and the bearing discharging pipe 14. The upper end of the support platform 13 is fixedly connected to the bearing automatic installation mechanism 3.

[0031] like Figure 6As shown, the automatic bearing installation mechanism 3 includes a receiving block 31, a fall arresting push block 32, a sliding connecting block 33, a moving slide rail 34, and a bearing installation cylinder 35. The moving slide rail 34 is fixedly connected to the upper end of the support platform 13. The lower end of the sliding connecting block 33 is slidably connected to the moving slide rail 34 via a slider. The upper end of the sliding connecting block 33 is fixedly connected to the fall arresting push block 32. The fall arresting push block 32 is slidably connected to the bearing unloading pipe 14. The fall arresting push block 32 has a clearance hole on its side wall near the support column 12 to avoid the rotating shaft 5. The receiving block 31 is fixedly connected to the side of the fall arresting push block 32 near the support column 12. The receiving block 31 is used to receive the bearing 6 in the bearing unloading pipe 14. The bearing installation cylinder 35 is fixedly connected to the support platform 13 via a connecting plate. The output end of the bearing installation cylinder 35 is fixedly connected to the fall arresting push block 32.

[0032] The receiving block 31 can be a U-shaped block. The inner walls on both sides of the U-shaped opening design can effectively wrap the bearing 6 to prevent it from rolling or shifting during the receiving process and ensure accurate positioning.

[0033] The receiving block 31 can be made of magnetic material, and the bearing 6 can be attracted to the U-shaped opening of the receiving block 31 by magnetic force to prevent it from rolling or falling due to inertia.

[0034] In this invention, the rotor 4 is transported to the rotor-dwelling conveyor mechanism 2 via the rotor loading pipe 10, and the bearing 6 is transferred from the bearing unloading pipe 14 to the receiving block 31. The bearing mounting cylinder 35 is activated, pushing the anti-fall pusher block 32 and the sliding connecting block 33 towards the rotor-dwelling conveyor mechanism 2. At this time, the anti-fall pusher block 32 blocks the outlet of the bearing unloading pipe 14, preventing the bearing 6 from falling from the bearing unloading pipe 14. Under the limiting action of the moving slide rail 34, the anti-fall pusher block 32 can only move horizontally. The movement causes the receiving block 31 to move, and the bearing 6 is installed on the rotor 4 on the rotor stationary conveyor mechanism 2. After the bearings 6 at both ends of the rotor 4 are installed simultaneously, the rotor stationary conveyor mechanism 2 moves the rotor 4 to the rotor discharge pipe 11. The output end of the bearing installation cylinder 35 is reset, and the anti-fall push block 32 and the receiving block 31 are reset. The anti-fall push block 32 can no longer block the bearing 6 from being discharged. The discharge port of the bearing discharge pipe 14 is aligned with the receiving block 31, and the bearing 6 is transferred from the bearing discharge pipe 14 to the receiving block 31.

[0035] In this utility model, the bearing mounting cylinder 35 pushes the anti-fall push block 32, which drives the receiving block 31 with the bearing 6 to move. The symmetrically distributed mechanism allows the bearing 6 to be installed at both ends of the rotor 4 simultaneously. At the same time, the blocking effect of the anti-fall push block 32 enables the automatic unloading of the bearing 6 during the movement and resetting process, ensuring the feasibility of the automatic continuous installation process of the bearing 6.

[0036] In some embodiments, please refer to the accompanying drawings. Figure 1 , Figure 2 , Figure 4 and Figure 5 The rotor-dwelling conveyor mechanism 2 includes an automatic loading and unloading assembly 21 and an adjustable support assembly 22. The automatic loading and unloading assembly 21 and the adjustable support assembly 22 are arranged between the rotor loading pipe 10 and the rotor unloading pipe 11. The automatic loading and unloading assembly 21 is used to realize the automatic loading and unloading of the rotor 4. The two adjustable support assemblies 22 are symmetrically distributed about the rotor loading pipe 10. The adjustable support assemblies 22 are used to support the rotor 4 and adjust its height.

[0037] like Figure 4 and Figure 5 As shown, the automatic loading and unloading assembly 21 includes an obstacle-crossing limit assembly and an obstacle-crossing drive assembly. There are two sets of obstacle-crossing limit assemblies, which are symmetrically distributed about the left and right sides of the rotor loading pipe 10. The obstacle-crossing drive assembly is located below the obstacle-crossing limit assemblies and is used to drive the obstacle-crossing limit assemblies.

[0038] like Figure 4 and Figure 5 As shown, the obstacle-crossing limiting assembly includes a rotor stop recess 211, a first rotor lifting recess 212, and a second rotor lifting recess 213. The rotor stop recess 211 is fixedly connected to the front end of the rotor feeding pipe 10 to prevent the rotor 4 from moving forward. The first rotor lifting recess 212 is located below the rotor feeding pipe 10, and the rotor feeding pipe 10 is provided with a clearance hole for avoiding the first rotor lifting recess 212. The second rotor lifting recess 213 is located below the first rotor lifting recess 212. Behind 12, the second rotor lifting recess 213 is slightly lower than the first rotor lifting recess 212. The first rotor lifting recess 212 and the second rotor lifting recess 213 are fixedly connected by a connecting plate. The upper ends of the first rotor lifting recess 212 and the second rotor lifting recess 213 are provided with inclined grooves for lifting and guiding the rotor 4 to move forward. The second rotor lifting recess 213 and the support column 12 are vertically limited and slidably connected by a sliding structure. The sliding structure can be a dovetail slider and a dovetail groove.

[0039] like Figure 4 and Figure 5 As shown, the obstacle crossing drive assembly includes a cylinder connecting push block 214 and a double-rod cylinder 215. The cylinder connecting push block 214 is fixedly connected to two sets of first rotor lifting recesses 212 and second rotor lifting recesses 213. The side of the double-rod cylinder 215 is fixedly connected to the support column 12 through a connecting plate. The output end of the double-rod cylinder 215 is fixedly connected to the cylinder connecting push block 214.

[0040] like Figure 4 and Figure 5As shown, the adjustable support assembly 22 includes a V-shaped bearing positioning block 221, a telescopic inner slide rod 222, a telescopic outer sleeve 223, and a locking knob 224. The lower end of the telescopic outer sleeve 223 is fixedly connected to the support column 12, and the upper end of the telescopic outer sleeve 223 is slidably connected to the telescopic inner slide rod 222. The side wall of the telescopic outer sleeve 223 is provided with a screw hole, and the screw hole is threaded with a locking knob 224 for fixing the telescopic inner slide rod 222 and the telescopic outer sleeve 223. The lower end of the V-shaped bearing positioning block 221 is fixedly connected to the telescopic inner slide rod 222, and the upper end of the V-shaped bearing positioning block 221 is provided with a V-shaped groove. The V-shaped bearing positioning block 221 is used to support and limit the rotor 4.

[0041] In this invention, the rotor 4 rolls downward along the rotor feeding pipe 10. The rotor 4 is blocked by the rotor stop recess 211. The double-rod cylinder 215 is activated, pushing the cylinder connecting push block 214 upward, which in turn moves the first rotor lifting recess 212 upward. Thus, the rotor 4 is transferred from the rotor feeding pipe 10 to the V-type bearing positioning block 221 to install the bearing 6. The double-rod cylinder 215 is reset. After the bearing 6 is installed, the double-rod cylinder 215 is activated, the second rotor lifting recess 213 moves upward, and the rotor 4 is transferred from the V-type bearing positioning block 221 to the rotor unloading pipe 11. The double-rod cylinder 215 is reset, and the above process is repeated.

[0042] In this invention, when the diameter of the rotor 4 changes, rotating the locking knob 224 will pull the telescopic inner slide rod 222 in the telescopic outer sleeve 223, adjusting the height of the V-shaped bearing positioning block 221 so that the center of the rotating shaft 5 and the center of the bearing 6 inside the receiving block 31 are on the same horizontal line. Rotating the locking knob 224 in the opposite direction will cause the inner side of the locking knob 224 to abut against the telescopic inner slide rod 222 to achieve fixation, thus allowing the bearing 6 to be installed on the rotor 4.

[0043] In this utility model, the rotor stop recess 211, the first rotor lifting recess 212, and the second rotor lifting recess 213 work together to achieve automatic loading and unloading of the rotor 4 with only one drive, which greatly improves production efficiency. The telescopic outer sleeve 223, the telescopic inner slide rod 222, and the locking knob 224 work together to adjust the height of the V-shaped bearing positioning block 221, so that bearings 6 can be installed on rotors 4 of different diameters.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
