[0002] Automotive automated production lines refer to systems that utilize technologies such as robots, automated equipment, intelligent control systems, and the Industrial Internet of Things to achieve efficient, precise, and flexible production throughout the entire automotive manufacturing process. Robotic arms are commonly used on automated production lines, and their steering is controlled by joint components within their structure.

[0003] In the prior art, the internal rotation of the robotic arm joint assembly is achieved through bearings. When lubricating the bearings, the lubricant is usually injected through a fixed oil injection channel. Since the oil injection channel is integrated with the device, it is difficult to clean the inside. Over time, impurities tend to accumulate inside the channel, which can easily cause blockages. Utility Model Content

[0004] The purpose of this utility model is to provide a robotic arm joint component for an automated automotive production line, in order to solve the problem mentioned in the background art that the oil injection channel and device are integrated, making it difficult to clean the inside, and that impurities easily accumulate inside the channel after long-term use, which can easily cause blockage inside the channel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: including: a first rotating mechanism, the first rotating mechanism including a first rotating frame, a drive motor, a bearing, a protective ring, a sealing ring, a hollow groove, a connecting port and a threaded groove, a second rotating mechanism being provided inside the first rotating mechanism, the second rotating mechanism including a second rotating frame, a groove and a sealing groove, and an oil injection assembly being provided inside the first rotating mechanism, the oil injection assembly including an oil injection pipe, a connecting pipe, a threaded ring, a protrusion and a protective plug.

[0006] In a preferred embodiment, one side of the first rotating frame is fixedly connected to one side of the housing of the drive motor, and the inner side of the other side of the first rotating frame is fixedly connected to the outer wall of the bearing.

[0007] In a preferred embodiment, the inner walls on both sides of the first rotating frame are fixedly connected to one side of the protective ring, and the inner wall of the protective ring is fixedly connected to the outer wall of the sealing ring.

[0008] In a preferred embodiment, a hollow groove is provided inside the first rotating frame on the side away from the drive motor, and a connection port is provided on one side of the hollow groove. A threaded groove is provided on the other side of the hollow groove, and the connection port is located on the side of the bearing ball.

[0009] In a preferred embodiment, the inner wall of the first rotating frame is movably connected to both sides of the second rotating frame, and one outer wall of the second rotating frame is rotatably connected to the inner wall of the bearing, and the other side of the second rotating frame is fixedly connected to the output end of the drive motor via a coupling.

[0010] In a preferred embodiment, grooves are provided on both outer walls of the second rotating frame, and sealing grooves are provided on the inner walls of the grooves. The outer walls of the grooves are movably connected to the outer walls of the protective ring, and the outer walls of the sealing ring are movably connected to the inner walls of the sealing grooves.

[0011] In a preferred embodiment, the inner wall of the hollow groove is movably connected to the outer wall of the oil injection pipe, one end of the oil injection pipe is fixedly connected to one end of the connecting pipe, and the outer wall of the connecting pipe is movably connected to the inner wall of the connecting port. The outer wall of the other end of the oil injection pipe is fixedly connected to the inner wall of the threaded ring.

[0012] In a preferred embodiment, the outer wall of the threaded ring is threadedly connected to the inner wall of the threaded groove, and the end of the oil injection pipe away from the connecting pipe is fixedly connected to one side of the protrusion, and the inner wall of one end of the oil injection pipe is movably connected to the outer wall of the protective plug.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model allows lubricating oil to be injected into the bearing through the oil injection pipe and connecting pipe after removing the protective plug. When it is necessary to clean the inside of the oil injection pipe, the oil injection pipe is rotated by rotating the protrusion. The rotation of the oil injection pipe causes the threaded ring to rotate on the inner wall of the thread groove, thereby moving the threaded ring out from the inside of the thread groove. Then the oil injection pipe can be removed, and the inside of the oil injection pipe can be cleaned. By removing the oil injection pipe, it is easier to clean the inside of the oil injection pipe, thus getting rid of the cumbersome internal cleaning of the traditional integrated channel and device.

[0015] 2. In this utility model, when the second rotating frame rotates inside the first rotating frame, the protective ring rotates inside the groove, and at the same time, the sealing ring rotates inside the sealing groove. By setting the sealing ring, external dust is blocked, reducing the amount of dust entering the bearing and increasing the service life of the device. Attached Figure Description

[0028] Specifically: when the second rotating frame 201 rotates inside the first rotating frame 101, the protective ring 104 rotates inside the groove 202, and at the same time the sealing ring 105 rotates inside the sealing groove 203.

[0029] In one embodiment, a hollow groove 106 is provided inside the first rotating frame 101 on the side away from the drive motor 102, and a connection port 107 is provided on one side of the hollow groove 106.

[0030] Specifically: The threaded groove 108 facilitates the removal of the oil injection pipe 301.

[0031] In one embodiment, the inner wall of the first rotating frame 101 is movably connected to both sides of the second rotating frame 201, and one outer wall of the second rotating frame 201 is rotatably connected to the inner wall of the bearing 103, and the other side of the second rotating frame 201 is fixedly connected to the output end of the drive motor 102 via a coupling.
