Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0024] Reference Figures 1-5 A device for press-fitting bearing oil seal assemblies includes a worktable 1. A frame 4 is bolted to the upper surface of the worktable 1. An electric push rod 5 is bolted to the top of the frame 4. A pressure block 10 is bolted to the extended end of the electric push rod 5. A round tube 6 is sleeved on the outside of the pressure block 10, and the round tube 6 is slidably connected to the extended end of the electric push rod 5. A first spring 11 is sleeved on the outside of the extended end of the electric push rod 5, and the two ends of the first spring 11 are respectively fixed to the round tube 6 and the pressure block 10. A turntable 2 is rotatably connected to the upper surface of the worktable 1. The interior of the turntable 2 is open. Multiple circular grooves 7 are provided. The oil seal is inserted into the bottom of the circular tube 6 and contacts the pressure block 10. Then the bearing is placed in the circular groove 7. The turntable 2 is rotated to move the bearing below the circular tube 6. A positioning component is provided between the turntable 2 and the worktable 1. The electric push rod 5 extends to allow the circular tube 6 to enter the bearing groove as a whole until the bottom of the circular tube 6 contacts the convex ring in the bearing groove. Then the electric push rod 5 continues to extend. At this time, the circular tube 6 is restricted and cannot move further. The pressure block 10 squeezes the oil seal and moves it downward along the circular tube 6 into the bearing, thereby installing the oil seal in the bearing.

[0025] In this utility model, it should be noted that the positioning component includes multiple positioning blocks 12, which are fixed to the outer wall of one side of the worktable 1 by bolts. A sliding groove 13 is provided inside each positioning block 12, and a sliding plate 15 is slidably connected within the groove 13. The groove 13 guides the sliding plate 15, enabling it to move stably. A second spring 14 is welded to the upper surface of the sliding plate 15 and is fixed to the positioning block 12. A hemispherical locking block 16 is fixed to the bottom of the sliding plate 15 by bolts. Multiple hemispherical slots 17 are provided around the turntable 2 on the upper surface of the worktable 1, and the hemispherical locking blocks 16 engage with the hemispherical slots 17. Rotating the turntable 2 moves the bearing below the circular tube 6, and simultaneously, the turntable 2 moves the hemispherical locking blocks 16 out of the hemispherical slots 17 and along the worktable 1. At this time, the sliding plate 15 moves upward along the groove 13, and the second spring 14... 4. Contract until the hemispherical locking block 16 moves into another hemispherical locking groove 17, and the second spring 14 returns to its original position, thereby providing auxiliary fixation for the moved turntable 2. The outer side of the extended end of the electric push rod 5 is fixed with a limit plate 9 by bolts, and the limit plate 9 is located inside the circular tube 6. The limit plate 9 can limit the height of the pressure block 10. The bottom inner wall of the circular tube 6 is provided with an annular groove 18, and a rubber ring 19 is bonded inside the annular groove 18. The outer side of the rubber ring 19 protrudes from the annular groove 18. During the installation of the oil seal, the oil seal squeezes the rubber ring 19, thereby enabling the oil seal to be stably installed inside the circular tube 6 and preventing it from falling off easily. A limit ring 8 is bonded inside the circular groove 7. The limit ring 8 is made of rubber to prevent the bearing from directly contacting the groove surface of the circular groove 7 and causing wear. The outer circumference of the turntable 2 is fixed with multiple fixing rods 3 by bolts, which facilitates the rotation of the turntable 2 by the operator.

[0026] Working principle: When it is necessary to press-fit an oil seal onto a bearing, first insert the oil seal into the bottom of the round tube 6 and make it contact with the pressure block 10. Then place the bearing into the round groove 7. Then rotate the turntable 2 to move the bearing below the round tube 6. At the same time, the turntable 2 moves and moves the hemispherical locking block 16 out of the hemispherical locking groove 17 and along the worktable 1. At this time, the slide plate 15 moves upward along the slide groove 13 and the second spring 14 contracts until the hemispherical locking block 16 moves into another hemispherical locking groove 17 and the second spring 14 returns to its original position. This helps to fix the moved turntable 2. Start the electric push rod 5. The electric push rod 5 extends and makes the round tube 6 enter the bearing groove as a whole until the bottom of the round tube 6 contacts the convex ring in the bearing groove. Then the electric push rod 5 continues to extend. At this time, the round tube 6 is restricted and cannot move further. The pressure block 10 squeezes the oil seal and moves it downward along the round tube 6 into the bearing. This allows the oil seal to be installed in the bearing.

[0027] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
