[0002] As global manufacturing transforms towards digitalization and intelligence, bearings, as core basic components in mechanical equipment, are widely used in various rotating mechanisms, such as motors, gearboxes, drive shafts, and wheel hubs. In the bearing assembly process, accurately and reliably pressing the bearing into the shaft or bearing housing bore is a crucial step, and its assembly accuracy and efficiency directly affect equipment performance and production efficiency.

[0003] Currently, bearings are mainly pressed into place manually. However, manual operation is slow, especially in mass production, which becomes a bottleneck. At the same time, repetitive physical labor is physically demanding for operators, leading to fatigue. Furthermore, manual pressing makes it difficult to accurately control the pressing force and depth, which can easily cause bearing misalignment, incomplete pressing, or over-pressing. It can also damage the inner and outer rings or rolling elements of the bearing, affecting the bearing's lifespan and the accuracy of equipment operation. Utility Model Content

[0023] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will provide further details.

[0024] Please refer to Figures 1-4 This utility model proposes an automatic bearing pressing device, including a fixed base plate 1. An assembly assembly is provided on the top of the fixed base plate 1. The assembly assembly is used to assemble and press the bearing body 21 and the bearing seat 20. Adjusting feet 2 are symmetrically installed at the four corners of the bottom of the fixed base plate 1 to adjust the level of the fixed base plate 1, which is conducive to the subsequent assembly of the bearing. Rubber shock-absorbing sleeves are installed on the outside of the adjusting feet 2.

[0025] The assembly includes a base 3, which is bolted to the top of a fixed base plate 1. A column 4 is fixedly installed on one side of the base 3. A support frame 5 is sleeved on the outside of the column 4 for installing and fixing the rack 13 and gear column 9. Fixing bolts 6 are installed inside the support frame 5 for adjusting the overall height of the support frame 5. A fixing rod 7 is bolted to the top of the support frame 5. A tension spring 8 is sleeved on the outside of the end of the fixing rod 7 for resetting the rack 13. The column 4 and the support frame 5 are fixed together by fixing bolts 6. The cross-section of the fixing rod 7 is L-shaped. The structure includes a gear column 9 rotatably mounted inside the support frame 5 to drive the rack 13. A handle 10 is mounted at one end of the gear column 9 to rotate it. A fixing plate 11 is mounted at the bottom of the tension spring 8, and two sets of limiting bolts 12 are symmetrically mounted inside the fixing plate 11 to limit the downward pressure of the bearing pressure plate 14. A rack 13 is mounted at the bottom of the fixing plate 11, and a bearing pressure plate 14 is mounted at the bottom of the rack 13 for pressing the bearing body 21. A sealing plate 15 is bolted to the side wall of the support frame 5 to facilitate maintenance and repair of the gear column 9 and rack 13. The handle 10 is inclined, the limiting bolt 12 and the fixing plate 11 are screwed together, the gear column 9 and the rack 13 mesh and drive each other, the rack 13 is located between the support frame 5 and the sealing plate 15, and the rack 13 is slidably disposed with respect to the inner wall of the support frame 5. When pressing the bearing body 21, after the user has placed the bearing seat 20 and the bearing body 21, the user presses the handle 10, the handle 10 drives the gear column 9 to rotate, the rotation of the gear column 9 drives the rack 13 to move downward, the downward movement of the rack 13 drives the bearing pressure plate 14 to move downward and the tension spring 8 to stretch. 4. Moving downwards presses the bearing body 21 into the bearing housing 20, thus completing the assembly between the bearing body 21 and the bearing housing 20, improving the assembly efficiency and installation accuracy of the bearing. The user can loosen the fixing bolts 6 to adjust the height of the support frame 5, and then adjust the overall height of the bearing pressure plate 14, which is beneficial for the subsequent pressing of the bearing body 21. After the pressing of the bearing body 21 is completed, the handle 10 is released, the tension spring 8 returns to its original position, and the return of the pull ring drives the rack 13 to move upwards. The movement of the rack 13 drives the gear column 9 to rotate, completing the reset of the gear column 9 and the handle 10.

[0026] The bearing guide sleeve 16 is bolted to the top of the base 3 for placing the bearing seat 20. Two sets of limiting rods 17 are slidably installed inside the bottom of the bearing guide sleeve 16. A lower pressure block 18 is installed at the top of the limiting rod 17. A buffer spring 19 is sleeved on the outside of the limiting rod 17 for buffering. The bearing seat 20 is placed on the top of the lower pressure block 18. The bearing body 21 is assembled inside the bearing seat 20. A cavity is opened inside the bearing guide sleeve 16. The buffer spring 19 is located between the lower pressure block 18 and the inner wall of the bearing guide sleeve 16. When assembling the bearing seat 20 and the bearing body 21, the user places the bearing seat 20 into the bearing guide sleeve 16 and then places the bearing body 21 into the bearing hole on the surface of the bearing seat 20. When pressing the bearing body 21, the buffer spring 19 will be compressed to a certain extent, which will buffer the bearing body 21 and the bearing seat 20.

[0027] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
