It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other without conflict. The same reference numerals used throughout the drawings indicate the same or similar parts.

[0032] It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature, or it may be indirectly fixed or connected to the other feature. In addition, the descriptions of up, down, left, right, etc. used in the present invention are only relative to the relative positional relationship of the components of the present invention in the drawings.

[0033] Reference Figure 1 to Figure 2 , a coupling 6 oiling device, comprising: an oiling mechanism 1, a weighing mechanism 2, a lifting mechanism 3, a taking mechanism 4, a base 5 and a controller;

[0034] In one embodiment, the oil filling mechanism 1 , the weighing mechanism 2 , the lifting mechanism 3 and the picking mechanism 4 are all connected to the controller, and the oil filling mechanism 1 , the weighing mechanism 2 , the lifting mechanism 3 and the picking mechanism 4 are all fixedly connected to the base 5 .

[0035] In one embodiment, the oiling mechanism 1 includes a pressurizing component, a lifting component, a first rotating component, a second rotating component and an oiling nozzle 11. The pressurizing component is connected to the oiling nozzle 11, the lifting component is fixedly connected to the base 5, the lifting component is slidingly connected to the first rotating component, the first rotating component is rotatably connected to the second rotating component, and the second rotating component is connected to the oiling nozzle 11; the lifting component drives the first rotating component to move up and down, the first rotating component drives the second rotating component to swing left and right, and the second rotating component drives the oiling nozzle 11 to rotate.

[0036] In one embodiment, the weighing mechanism 2 is used to place the coupling 6, the lifting mechanism 3 drives the hoop-shaped teeth in the coupling 6 to move up and down, and the taking mechanism 4 transfers the filled coupling 6 to a designated position.

[0037] In one embodiment, the main function of the weighing mechanism 2 is to detect the weight of the first oil injection and the weight of the second oil injection, and ensure that the total weight of the two oil injections meets the process requirements. The detection accuracy of the entire weighing mechanism 2 is ±3g, and the range is 0-50kg, which can meet the requirements of the maintenance process of the coupling 6. The weighing mechanism 2 also has an automatic recording and storage function, which can display the data of each weighing in real time, so that the operator can check and adjust it at any time. By transmitting the weighing information to the controller, it can be ensured that the amount of oil injection does not exceed the process requirements, and the amount of oil injection for each coupling 6 is recorded, which is convenient for the production management system to trace the source. The weighing mechanism 2 adopts an advanced high-precision resistive strain type weighing sensor, which can accurately measure the weight and transmit the weighing signal to the transmitter via cable or wirelessly. The transmitter converts the weighing signal into a standard signal, and transmits the weighing information to the control unit through the communication module to ensure that the amount of oil injection does not exceed the process requirements.

[0038] The coupling 6 is placed on the weighing mechanism 2, and the controller controls the oiling mechanism 1 and the lifting mechanism 3 to oil the coupling 6. During the oiling process, the lifting assembly drives the oiling nozzle 11 to rise to a suitable position, and at the same time, the lifting mechanism 3 raises the hoop-shaped teeth in the coupling 6 to a suitable position, starts the second rotating assembly, and oils the outer teeth of the hoop-shaped teeth; then, the lifting mechanism 3 lowers the hoop-shaped teeth back into the coupling 6, and at the same time, the lifting assembly lowers the oiling nozzle 11 to a suitable position, starts the second rotating assembly, and refuels the coupling 6 for the second time; the weighing mechanism 2 ensures that the total weight of the two oilings meets the process requirements. The coupling 6 oiling device of the present invention has the characteristics of accurate weight and uniform distribution of the lubricating oil inside the coupling 6. After using the automatic assembly station for coupling 6, the production and maintenance efficiency of coupling 6 can be increased by 20%, from the original 2 people completing 8 coupling 6 assemblies per day to 2 people completing 10 per day. A single coupling 6 can save 0.4 hours of work. Based on the annual maintenance output of 2,000 coupling 6s, a total of 800 hours can be saved, greatly reducing the labor intensity of operators.

[0039] In one embodiment, the lifting assembly includes a first lifting motor, a slide slot 12 and a slider 13, the first rotating assembly includes a first rotating motor 14, the slide slot 12 is slidably connected to the slider 13, the first lifting motor is fixedly connected to the slider 13, the first rotating motor 14 is fixedly connected to the slider 13, and the first lifting motor drives the first rotating motor 14 to move up and down along the length direction of the slide slot 12 through the slider 13.

[0040] In one embodiment, the lifting assembly can automatically adjust the height of the oiling nozzle 11 according to the outer teeth of the coupling 6 or the meshing state of the outer teeth and the hoop-shaped teeth, so as to adapt to the refueling needs of different vehicle models and couplings 6. When the coupling 6 needs to be oiled with the outer teeth, the oiling nozzle 11 will extend into the bottom of the teeth of the coupling 6 to ensure accurate injection of oil; and when the outer teeth and the hoop-shaped teeth are meshed, the oiling nozzle 11 will rise to the height of the hoop-shaped teeth so as to inject an appropriate amount of oil into the two teeth at the same time. It can greatly reduce the operating burden of workers and improve the accuracy and production efficiency of refueling. At the same time, since the height of the oiling nozzle 11 can be quickly adjusted, it can adapt to various vehicle models and different models of couplings 6, and has good versatility and flexibility.

[0041] In one embodiment, the first rotating assembly further includes a first connecting plate 15, the second rotating assembly includes a second rotating motor 16, the second rotating motor 16 is fixedly connected to the first connecting plate 15, the output end of the first rotating motor 14 is fixedly connected to the first connecting plate 15, and the first rotating motor 14 drives the second rotating motor 16 to swing left and right through the first connecting plate 15. The rotation angle of the first connecting plate 15 is 90°.

[0042] In one embodiment, when the first rotating assembly manually places the hoop-shaped teeth into the outer teeth of the coupling 6, or when the finished product needs to be moved away from the oiling station by the picking mechanism 4 after oiling, the first rotating motor 14 can rotate the oiling nozzle 11 and other tools by 90° to free up the necessary space. During operation, the first connecting plate 15 is driven by the first rotating motor 14 to rotate 90°, so that the center point of the first rotating motor 14 and the center point of the coupling 6 are on the same vertical midline, so that the oiling nozzle 11 can accurately move around the center of the coupling 6 when rotating. This device can effectively solve the problem of space limitation in the operation process and improve the flexibility and efficiency of the entire production process. At the same time, the first rotating motor 14 and the second rotating motor 16 can accurately control the rotation angle to ensure that the position of the oiling nozzle 11 and other tools after rotation is accurate.

[0043] In one embodiment, the second rotating assembly further includes a second connecting plate 17, the output end of the second rotating motor 16 is fixedly connected to the second connecting plate 17, and the second connecting plate 17 is fixedly connected to the oiling nozzle 11. The rotation angle of the oiling nozzle 11 is 360°.

[0044] In one embodiment, the second rotating assembly has high rigidity and stability, and can make the oiling nozzle 11 perform a 360° rotational motion in a plane around the center point of the coupling 6 sample. During the oiling process, the second rotating motor 16 can rotate the oiling nozzle 11 at a constant speed, so that each position of the coupling 6 can be evenly covered by the coupling 6 oil, ensuring that each part of the coupling 6 can be fully lubricated. The second rotating motor 16 is controlled by a controller, and can achieve precise speed control and position adjustment, ensuring the accuracy and stability of the rotation speed and position.

[0045] In one embodiment, the pressurizing assembly includes an oil pipe connected to the oiling nozzle 11 .

[0046] In one embodiment, the lifting mechanism 3 includes a second lifting motor 31, a first push rod 32 and a tooling piece 33. The second lifting motor 31 is connected to the first push rod 32. The other end of the first push rod 32 is fixedly connected to the tooling piece 33. The tooling piece 33 is adapted to the bottom of the hoop-shaped tooth.

[0047] In one embodiment, after the outer teeth of the coupling 6 are oiled, the hoop-shaped teeth need to be placed inside the coupling 6 and oiled again. Since the hoop-shaped teeth and the outer teeth of the coupling 6 are meshed, and the teeth have high precision, no bumps or damage to the parts are allowed. Therefore, the hoop-shaped teeth of the coupling 6 can only be raised to a certain position (the distance can be set), and then the hoop-shaped teeth of the coupling 6 can be aligned with the tooth position line and gently placed on the support plate, and then the lifting mechanism 3 can be lowered to the working position to ensure that the parts are not damaged. An efficient and accurate assembly process of the coupling 6 can be achieved.

[0048] In one embodiment, the taking mechanism 4 includes a third rotating motor, a third connecting plate 41, a third lifting motor 42, a second push rod 43 and a gripper 44.

[0049] In one embodiment, the picking mechanism 4 has the functions of rotation and lifting, and the handling of the coupling 6 is achieved by adjusting the position of the gripper 44, which can reduce the burden of workers in handling and effectively reduce the labor intensity of workers. The picking steps include:

[0050] (1) Preparation stage: The initial position of the picking mechanism 4 is in the standby area, and the gripper 44 is in a released state.

[0051] (2) Move to the grabbing position: Through sensors and servo positioning technology, the picking mechanism 4 moves to a position suitable for grabbing the coupling 6 according to a preset trajectory.

[0052] (3) Lifting the gripper 44: Under the command of the controller, the gripper 44 on the picking mechanism 4 is automatically lifted and lowered by the third lifting motor 42 driving the second push rod 43 to reach a height suitable for grabbing the coupling 6.

[0053] (4) Clamping the coupling 6: The gripper 44 clamping device will automatically start and clamp the coupling 6 tightly.

[0054] (5) Translational transport: The picking mechanism 4 moves along a preset trajectory and transports the grabbed coupling 6 to a specified position.

[0055] (6) Release the coupling 6: After reaching the specified position, the gripper 44 will automatically release and put down the coupling 6.

[0056] (7) Return to the standby area: The picking mechanism 4 moves along a preset trajectory and returns to the standby area to wait for the next handling task.
