[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0031] Refer to Figures 1-3, An embodiment provided by the utility model: A bearing oil seal assembly device for planetary gear reduction, including an operating table 1, a bracket 2 is fixedly connected to one side of the operating table 1, a first limiting column 3 is fixedly connected to one side of the bracket 2, a fixing column 4 is slidably connected to the outer wall of the first limiting column 3, one end of the fixing column 4 is fixedly connected to a connecting plate 5, a hydraulic rod 6 is fixedly connected to one side of the bracket 2, and the output end of the hydraulic rod 6 is fixedly connected to one side of the connecting plate 5. One end of the fixing column 4 is fixedly connected to a motor 7, the output end of the motor 7 is fixedly connected to a threaded rod 8, a connecting disk 9 is threadedly connected to the outer wall of the threaded rod 8, an L-shaped support rod 11 is rotatably connected to the outer wall of the connecting disk 9, a connecting shaft 12 is fixedly connected inside the L-shaped support rod 11, both ends of the connecting shaft 12 are rotatably connected inside the fixing column 4, and a reset assembly is arranged inside the fixing column 4. The reset assembly is used to make the connecting disk 9 extend out of the fixing column 4. The reset assembly includes a spring 10, the spring 10 is sleeved on the outer wall of the threaded rod 8, one end of the spring 10 is fixedly connected to one side of the connecting disk 9, and the other end of the spring 10 is fixedly connected to the inside of the fixing column 4;
[0032] Specifically, first, place the bearing inside the fixing column 4. This step ensures that the bearing is accurately positioned at the starting point of the assembly process, laying the foundation for subsequent operations. Then, start the output end of the motor 7 to drive the threaded rod 8 to start rotating. The rotation of the threaded rod 8 pushes the connecting disk 9 to move along the linear track inside the fixing column 4. The movement of the connecting disk 9 guides the L-shaped support rod 11 to rotate around the connecting shaft 12. The connecting shaft 12 serves as the rotation center point, making one end of the L-shaped support rod 11 gradually extend into the inside of the fixing column 4. At the same time, the other end of the L-shaped support rod 11 firmly clamps and fixes the bearing, ensuring the stability and safety of the bearing during installation. The output end of the hydraulic rod 6 extends, and through the connecting plate 5 as an intermediary, drives the fixing column 4 to extend outwards. This action enables the bearing inside the fixing column 4 to be successfully installed on the planetary gear reducer, ensuring its correct assembly position and function.
[0033] Refer to Figure 4 , a first fixing plate 13 is fixedly connected to the top of the operating table 1, a slide rail 14 is fixedly connected to the top of the first fixing plate 13, a connecting frame 15 is slidably connected to the outer wall of the slide rail 14, a first limiting wheel 17 is rotatably connected inside the connecting frame 15, a fixing bolt 16 is threadedly connected inside the connecting frame 15, one end of the fixing bolt 16 abuts against the outer wall of the slide rail 14, a second fixing plate 18 is fixedly connected to one side of the first fixing plate 13, a connecting block 19 is fixedly connected to the top of the second fixing plate 18, a second limiting column 20 is fixedly connected to one side of the connecting block 19, an electric push rod 21 is fixedly connected to the top of the second fixing plate 18, the output end of the electric push rod 21 is fixedly connected to a cross plate 22, a second limiting wheel 23 is rotatably connected inside the cross plate 22, a limiting plate 24 is fixedly connected to one side of the cross plate 22, and one end of the limiting plate 24 is slidably connected to the outer wall of the second limiting column 20;
[0034] Specifically, placing the planetary gear reducer on the first fixed plate 13 is the primary step of the installation. Subsequently, the output end of the electric push rod 21 extends out, driving the second limiting wheel 23 through the cross plate 22 to precisely position and clamp the planetary gear reducer. The function of the second limiting wheel 23 is to ensure the accuracy and stability of the position of the planetary gear reducer during the installation process, thus guaranteeing its normal operation and safe operation. When it is necessary to adjust planetary gear reducers of different sizes, the operation is simple. Just loosen the fixing bolt 16, then move the position of the first limiting wheel 17 on the slide rail 14. After the adjustment is completed, tighten the fixing bolt 16 again to fix the first limiting wheel 17. This process effectively allows adjusting the position and size of the planetary gear reducer according to specific requirements to adapt to different working environments and requirements. The cross plate 22 limits the outer wall of the second limiting post 20 through the limiting plate 24, ensuring the stability and controllability of the cross plate 22 during the movement. This design ensures that the second limiting wheel 23 can accurately perform its positioning and clamping functions without affecting the assembly quality and operation effect of the planetary gear reducer due to instability during the movement process.
[0035] Working principle: When using this bearing oil seal assembly device for the planetary gear reducer, first, when installing the bearing, place the bearing inside the fixed post 4. Subsequently, the output end of the motor 7 drives the threaded rod 8 to rotate. When the threaded rod 8 rotates, it drives the connecting plate 9 to move inside the fixed post 4. When the connecting plate 9 moves, it drives the L-shaped support rod 11 to rotate around the connecting shaft 12. One end of the L-shaped support rod 11 connected to the connecting plate 9 extends into the interior of the fixed post 4, and the other end of the L-shaped support rod 11 clamps and fixes the bearing. Subsequently, place the planetary gear reducer on the first fixed plate 13. The output end of the electric push rod 21 extends out and drives the second limiting wheel 23 through the cross plate 22 to position and clamp the planetary gear reducer. Subsequently, the output end of the hydraulic rod 6 extends out and drives the fixed post 4 to extend through the connecting plate 5, so that the bearing inside the fixed post 4 is installed on the planetary gear reducer. The fixed post 4 is limited by the first limiting post 3. When it is necessary to adjust planetary gear reducers of different sizes, just loosen the fixing bolt 16, then move the position of the first limiting wheel 17 on the slide rail 14, and then tighten the fixing bolt 16 again to fix the first limiting wheel 17. The cross plate 22 is limited on the outer wall of the second limiting post 20 through the limiting plate 24.
[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
