[0035] In one embodiment, the oil injection mechanism 1 comprises a pressurizing assembly, a lifting assembly, a first rotating assembly, a second rotating assembly and an oil injection nozzle 11, the pressurizing assembly is connected with the oil injection nozzle 11, the lifting assembly is fixedly connected with the base 5, the lifting assembly is slidingly connected with the first rotating assembly, the first rotating assembly is rotatably connected with the second rotating assembly, and the second rotating assembly is connected with the oil injection nozzle 11; the lifting assembly drives the first rotating assembly to move up and down, the first rotating assembly drives the second rotating assembly to swing left and right, and the second rotating assembly drives the oil injection 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 the 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 to 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, the range is 0-50kg, and it can meet the requirements of the coupling 6 repair process. The weighing mechanism 2 also has automatic recording and storage functions, and can display the data of each weighing in real time, so that the operator can check and adjust at any time. By transmitting the weighing information to the controller, it can ensure that the oil injection amount does not exceed the process requirements, and record the oil injection amount of each coupling 6, so as to facilitate the production management system to trace the source. The weighing mechanism 2 uses advanced high-precision resistance strain type weighing sensor, which can accurately measure the weight and transmit the weighing signal to the transmitter through cable or wireless way. The transmitter converts the weighing signal into a standard signal and transmits the weighing information to the control unit through the communication module, so as to ensure that the oil injection amount does not exceed the process requirements.

[0038] The coupling 6 is placed on the weighing mechanism 2, and the oil injection mechanism 1 and the lifting mechanism 3 are controlled by the controller to inject oil into the coupling 6. During the oil injection process, the lifting assembly drives the oil injection nozzle 11 to rise to a suitable position, and at the same time, the lifting mechanism 3 drives the hoop-shaped teeth in the coupling 6 to rise to a suitable position, and the second rotating assembly is started to inject oil into the outer teeth of the hoop-shaped teeth; subsequently, the lifting mechanism 3 drives the hoop-shaped teeth to descend back into the coupling 6, and at the same time, the lifting assembly drives the oil injection nozzle 11 to descend to a suitable position, and the second rotating assembly is started to inject oil into the coupling 6 for the second time; the weighing mechanism 2 ensures that the total weight of the two times of oil injection meets the process requirements. The coupling 6 oil injection device has the characteristics of precise weight and uniform distribution of the internal lubricating oil of the coupling 6. After using the automatic coupling 6 assembly station, the production and maintenance efficiency of the coupling 6 can be improved by 20%, from the original 8 couplings 6 assembled per day by 2 people to 10 couplings 6 assembled per day by 2 people, and the single coupling 6 can save 0.4 hours of working hours. According to the annual maintenance output of 2000 couplings 6, a total of 800 hours can be saved, which greatly reduces the labor intensity of the operating personnel.

When the coupling 6 needs to be injected with oil, the oil injection nozzle 11 will extend into the bottom of the coupling 6 teeth to ensure accurate injection of oil; when the outer teeth and the hoop-shaped teeth are meshed, the oil injection nozzle 11 will rise to the height of the hoop-shaped teeth to inject an appropriate amount of oil into both teeth at the same time. This can greatly reduce the operating burden of workers and improve the accuracy of oil injection and production efficiency. At the same time, since the height of the oil injection nozzle 11 can be quickly adjusted, it can adapt to various vehicle models and different types of couplings 6, and has good universality and flexibility.

[0042] In one embodiment, the first rotating assembly can rotate the oiling nozzle 11 and other tooling by 90° through the first rotating motor 14 when the collar teeth are manually put into the outer teeth of the coupling 6, or when the finished product needs to be moved away from the oiling station by the taking mechanism 4 after oiling. When working, the first connecting plate 15 is driven to rotate by 90° by the first rotating motor 14, so that the center point of the first rotating motor 14 is on the same vertical center line as the center point of the coupling 6, so that the oiling nozzle 11 can accurately move around the center of the coupling 6 when rotating.

[0047] In one embodiment, after the outer teeth of the coupling 6 are oiled, the collar teeth need to be put into the coupling 6 and oiled again. Since the collar teeth and the outer teeth of the coupling 6 are meshed, and the teeth have high precision, they are not allowed to be damaged. Therefore, after the lifting mechanism 3 is lifted to a certain position (the distance can be set), the collar teeth of the coupling 6 are aligned with the tooth position line and gently placed on the support plate, and then the lifting mechanism 3 is lowered to the working position, so as to ensure that the parts are not damaged.
