Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] Please see Figures 1-5A slewing bearing oil injection device includes a mounting plate 1. A clamping structure and a driving structure are mounted on the bottom end of the mounting plate 1, and an oil injection structure is mounted on the top end of the mounting plate 1. A handle 2 is rotatably mounted on the top end of the mounting plate 1. The driving structure includes a clamping motor 3 and a fixing plate 4. Both the fixing plate 4 and the clamping motor 3 are fixedly mounted on the bottom end of the mounting plate 1. A clamping screw 5 is fixedly connected to the output end of the clamping motor 3. The clamping screw 5 is rotatably connected to the fixing plate 4. A moving block 6 is threadedly connected to the external end of the clamping screw 5. A moving plate 7 is fixedly connected to the bottom end of the moving block 6. A clamping block 8 is fixedly connected to the outer wall of the moving plate 7. The driving structure includes a second fixing plate 9, which is fixedly connected to the bottom end of the mounting plate 1. A fixed block 10 is fixedly connected to the wall. A drive wheel 11 is rotatably installed inside the fixed block 10, and a drive motor 12 is fixedly installed at the top of the fixed block 10. The output end of the drive motor 12 is fixedly connected to the drive wheel 11. The oil injection structure includes an oil injection motor 13, an oil storage tank 14, and an oil injection hose 15. The oil injection motor 13 and the oil storage tank 14 are both fixedly installed at the top of the mounting plate 1. An oil pusher plate 16 is slidably installed inside the oil storage tank 14. An oil pusher screw 17 is fixedly connected to the output end of the oil injection motor 13. The oil pusher screw 17 is threadedly connected to the oil pusher plate 16. An oil filling pipe 18 is installed at the top of the oil storage tank 14. The oil injection hose 15 is connected to the oil storage tank 14. An oil injection head 19 is installed at the oil outlet end of the oil injection hose 15.

[0029] The handle 2 facilitates the movement of the device, improving its ease of use. When the clamping motor 3 operates, the clamping screw 5 rotates, causing the moving block 6 to move the moving plate 7. This allows the clamping block 8 and the drive wheel 11 to clamp the bearing together. When the drive motor 12 operates, the drive wheel 11 rotates, causing the outer ring of the bearing to rotate, facilitating quick and easy oiling and improving oiling efficiency. When the oiling motor 13 operates, it drives the oil-pushing screw 17 to rotate, causing the oil-pushing plate 16 to move. This pushes the lubricating oil inside the oil tank 14 into the oiling hose 15, and finally delivers it to the bearing through the oiling head 19, achieving a uniform oiling effect and improving the oiling efficiency for practical use.

[0030] Please see Figure 1 and Figure 2 A support block 20 is fixedly connected to the bottom of the mounting plate 1.

[0031] The support block 20 allows the device to be stably placed on top of the bearing during use, thereby improving the stability of the device and facilitating the stable operation of the oil injection process.

[0032] Please see Figure 1 and Figure 2 Anti-slip pads 21 are installed on the outer walls of both the clamping block 8 and the drive wheel 11.

[0033] The anti-slip pad 21 improves the clamping effect on the bearing, thereby enabling stable rotation of the outer ring of the bearing.

[0034] Please see Figure 1 The movable plate 7 and the movable block 6 are fixedly connected by a reinforcing rib 22, and the fixed plate 9 and the mounting plate 1 are fixedly connected by a reinforcing rib 23.

[0035] The addition of reinforcing ribs 1 (22) and 23 can improve the stability of the moving plate 7 and the fixed plate 2 (9), further enhancing the clamping effect.

[0036] Please see Figure 5 A sealing plate 24 is fixedly connected to the outer wall of the oil pusher screw 17. A sealing bearing 25 is installed between the sealing plate 24 and the oil reservoir 14. A sealing gasket 26 is installed on the outer wall of the oil pusher plate 16.

[0037] The sealing plate 24, sealing bearing 25 and sealing gasket 26 ensure that the lubricating oil inside the oil tank 14 will not leak, and that the lubricating oil can be stably delivered to the inside of the oil injection hose 15 during the movement of the oil pusher plate 16.

[0038] Please see Figure 4 The outer wall of the oil filling head 19 is equipped with an anti-slip pad 27.

[0039] The anti-slip pad 27 can increase the friction between the oil injection head 19 and the bearing, thereby preventing the oil injection head 19 from separating from the bearing and ensuring the stable progress of the oil injection process.

[0040] In summary, the working principle and process of this slewing bearing lubrication device are as follows: First, lubricating oil is added to the oil reservoir 14 through the oil filling pipe 18. Then, the device is moved using handle 2 to position it above the bearing, ensuring the support block 20 contacts the bearing surface. Next, the clamping motor 3 is started, causing the clamping screw 5 to rotate. Driven by the moving block 6 and moving plate 7, the clamping block 8 approaches the outer wall of the bearing's inner ring, working in conjunction with the drive wheel 11 to clamp the bearing. Afterward, the drive wheel 11 can be started. The motor 12 drives the wheel 11 to rotate the outer ring of the bearing under the action of friction, which helps to improve the oil injection efficiency and ensure the stability of the oil injection process. After inserting the oil injection head 19 into the oil filling port on the outer wall of the bearing, the oil injection motor 13 is started, which causes the oil push screw 17 to drive the oil push plate 16 to move. The lubricating oil is delivered to the inside of the bearing through the oil injection head 19 under the delivery action of the oil injection hose 15, which can achieve a uniform oil injection effect, good oil injection effect, high oil injection efficiency, and is beneficial to practical use.

[0041] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
