[0002] In the production, assembly, or maintenance of universal joint bearings, the lubrication process is the core link to ensure its lubrication performance. Currently, the lubrication of universal joint bearings is mostly done manually or by semi-automatic equipment. Manual lubrication is not only labor-intensive and inefficient, but also results in poor consistency of lubrication volume. Although semi-automatic equipment can achieve batch transportation of bearings through a conveying mechanism, it still has significant shortcomings in bearing positioning accuracy and pushing stability, which has become a key bottleneck restricting the accuracy of lubrication and the level of automation.

The oiling mechanism includes an oiling clamp, an oiling head, and a first lifting cylinder. The oiling head is mounted on the first lifting cylinder and positioned above the oiling clamp. A transfer conveyor belt is located next to the press, and a first tilting mechanical claw is positioned between the transfer conveyor belt and the oiling clamp. This invention can automatically transfer the press-assembled ball cage universal joints to the oiling station for automatic oiling, improving production efficiency and ensuring consistent product quality and high stability through automated oiling.

[0021] Example like Figure 1-2 As shown, this utility model provides an automatic oiling device for universal joint bearings, including: a drive assembly 1, a limit guide assembly 2, a push cylinder assembly 4, and an oiling assembly 5.

[0022] The drive assembly 1 includes a drive motor 11 and a conveyor belt 12. The drive motor 11 is mounted on one side of the conveyor belt 12, and its output shaft is connected to the drive wheel shaft of the conveyor belt 12 via a synchronous belt transmission mechanism. Starting the drive motor 11 drives the conveyor belt 12 to move. Support feet are fixedly installed at the bottom of both the drive motor 11 and the bottom of the conveyor belt 12 for support. The limiting and guiding assembly 2 includes a limiting baffle 21 and a positioning push plate 22. The limiting baffle 21 consists of two parallel baffles spaced apart on the conveying surface of the conveyor belt 12, with a universal joint bearing to be lubricated placed between them. The positioning push plate 22 is located on one side of a fixed plate 3 and is perpendicular to the limiting baffle 21. Support feet are also fixedly installed at the bottom of the fixed plate 3 for support.

[0023] The pushing cylinder assembly 4 includes a first pushing cylinder 41 and a second pushing cylinder 42. The first pushing cylinder 41 is located at the end of the conveyor belt 12 and has a first piston rod 411 on it. A first pusher head 412 is installed at the end of the first piston rod 411 to push the universal joint bearing conveyed on the conveyor belt 12 toward the fixed plate 3 for subsequent oiling. More specifically, the first piston rod 411 is slidably disposed in the cylinder of the first pushing cylinder 41 in the horizontal direction, and can be freely adjusted to push according to the specific position of the universal joint bearing conveyed to the end of the conveyor belt 12.

[0024] The second pushing cylinder 42 is located on the other side of the fixed plate 3, and a second piston rod 421 is mounted on it. The end of the second piston rod 421 is connected to a second pushing head 422. It is worth noting that the pushing end face of the second pushing head 422 has a planar structure on both sides and a triangular concave structure in the middle, which can fit the outer circumference of universal joint bearings of different specifications, stably positioning the universal joint bearings and preventing slippage of the universal joint bearings during oil filling, which would lead to grease leakage and waste.

[0025] Preferably, the fixed plate 3 is provided with a linear sliding groove 31. More specifically, the positioning push plate 22 and the second push head 422 are both slidably disposed in the linear sliding groove 31 by a slider. The linear sliding groove 31, together with the slider, forms a precise linear motion guide, ensuring that the positioning push plate 22 and the second push head 422 do not deviate or jam during the pushing process, thereby improving the accuracy of the universal joint bearing positioning and pushing.

[0026] Preferably, the upper part of the support foot is higher than the height of the conveyor belt 12. The outer side of the limiting baffle 21 is slidably connected to the upper part of the support foot, and the limiting baffle 21 is slidably disposed on the conveyor belt 12 along the width direction of the conveyor belt 12. The position of the limiting baffle 21 can be freely adjusted to adapt to universal joint bearings of different specifications, ensuring the stability of the conveying process. The oiling assembly 5 includes an oiling machine 51 and an oiling base 52. The oiling machine 51 is fixedly installed on the oiling base 52, and the oiling base 52 is slidably mounted on a linkage drive mechanism 53. The linkage drive mechanism 53 drives the oiling base 52 to move. The linkage drive mechanism 53 is also provided with a drive cylinder 54, and the drive cylinder 54 is provided with a third piston rod 55. The third piston rod 55 is operatively connected to the oiling mounting seat 52.

[0027] Preferably, the oiling machine 51 is a quantitative oiling machine, which can accurately inject lubricating oil according to preset oil quantity parameters, avoid oil quantity deviation caused by manual operation or ordinary oiling equipment, ensure that the oil quantity of each universal joint bearing is consistent, and thus ensure the stability and consistency of the product's lubrication performance.

[0028] Work process (1) According to the specifications of the universal joint bearing to be processed, slide and adjust the two parallel spaced limit baffles 21 along the width direction of the conveyor belt 12 so that the distance between the limit baffles 21 matches the outer diameter of the universal joint bearing, ensuring that the universal joint bearing does not deviate during the conveying process; at the same time, adjust the position of the positioning push plate 22 through the linear sliding groove 31 on the fixed plate 2 so that its initial state is perpendicular to the limit baffles 21, preparing for subsequent positioning. The support feet form a stable support for the drive assembly 1 and the fixed plate 3, ensuring that the overall equipment runs smoothly. (2) Start the drive motor 11, which drives the conveyor belt 12 to rotate. Place the universal joint bearings one by one on the conveyor belt 12 and move it towards the end; (3) When the universal joint bearing is conveyed to the end position, the first push cylinder 41 is started, the first piston rod 411 in its cylinder extends out, and drives the first push head 412 at the end to move towards the fixed plate 3, pushing the universal joint bearing from the conveying belt 12 to the positioning area of ​​the fixed plate 3, thus completing the transition of the universal joint bearing from the conveying link to the positioning link. (3) After the first pusher head 412 is reset, the second pusher cylinder 42 is started. Its second piston rod 421 drives the second pusher head 422 to slide along the linear sliding groove 31 on the fixed plate 3. The universal joint bearing moves along the conveying direction perpendicular to the conveying belt 12. At the same time, the positioning push plate 22 cooperates to limit the movement, so that the universal joint bearing is accurately placed at the preset oiling position directly below the quantitative oiling machine 51, and the precise positioning before oiling is completed. (4) The drive cylinder 54 on the linkage drive mechanism 53 is started, and its third piston rod 55 extends, driving the oil injection base 52 to descend. Then the oil injection machine 51 approaches the oil injection port. After the oil injection machine 51 reaches the preset oil injection position, the oil injection machine 51 injects lubricating oil into the universal joint bearing according to the set oil injection amount to complete the oil injection operation. Then the oil injection base 52 and the second push head 422 are reset. The positioning push plate 22 can also be adjusted to the initial position as needed, waiting for the next universal joint bearing to enter the positioning area. The equipment enters the next working cycle to realize continuous automated oil injection operation.
