Description

Technical Field

[0001] This application relates to the field of robotic arm technology, and in particular to a robotic arm joint with a lubrication structure. Background Technology

[0002] In modern industrial production and automated operations, robotic arms are an important type of automated equipment, undertaking various tasks such as material handling, parts processing, and assembly. As the key component for achieving flexible movement, the performance of the robotic arm joints directly affects the working efficiency and accuracy of the robotic arm.

[0003] A search revealed that patent application number CN202321569247.6 discloses a lubrication device for robotic arm joints, relating to the field of robotic arm technology. The device includes a first robotic arm and a second robotic arm, hinged together by a pivot. The outer surface of the first robotic arm is provided with a lubrication mechanism, which includes two grooves formed on the inner wall of the first robotic arm. A hollow ring is fixedly connected to the inner wall of each groove. The outer surfaces of the two hollow rings, which are close to each other, are fixedly connected to a ring-shaped array of nozzles. A fixing ring is fixedly connected to the outer surface of the first robotic arm. The device uses an oil pump to inject lubricating oil from an oil reservoir into two oil delivery pipes. These pipes then inject the lubricating oil into the two hollow rings. Simultaneously, the hollow rings spray the lubricating oil evenly at the hinge joint of the first and second robotic arms through the nozzles, performing lubrication work. This allows the device to automatically and quickly lubricate the joints of the robotic arms.

[0004] Although the device can lubricate the joints of the robotic arm during use, lubricating oil drips onto the operating table and excess lubricating oil drips from the nozzle during the oil spraying process, resulting in waste of lubricating oil and pollution of the operating environment.

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0023] This application discloses a robotic arm joint with a lubrication structure, including a robotic arm body 1. One end of the robotic arm body 1 is provided with symmetrical rotating shafts on the left and right sides. One end of the rotating shafts is connected to bearing seats provided on the side walls of both ends of the rotating seat 2. One end of the robotic arm body 1 is also provided with symmetrical lubrication structures on the left and right sides. The rotating seat 2 is fixedly installed on the top of the base 3. An oil storage box 4 is provided on the top of the base 3 at the edge of the rotating seat 2. The lubrication structure is also connected to the oil storage box 4.

[0024] refer to Figure 2 and Figure 3 The lubrication structure includes an oil spray ring 5 installed on the left and right sides of one end of the robotic arm body 1. The oil spray ring 5 is fixedly installed on the inner walls of both sides of the rotating seat 2 and is adapted to the rotating shafts on the left and right sides of one end of the robotic arm body 1. The top of the oil spray ring 5 is connected to an oil inlet hose 6, and the other end of the oil inlet hose 6 is connected to an oil pump 7 installed on the top of the oil storage box 4. Multiple oil nozzles 8 are also provided on one side of the oil spray ring 5. More specifically, by fixing the oil spray ring 5 on the inner walls of both sides of the rotating seat 2 and adapting it to the rotating shafts on the left and right sides of one end of the robotic arm body 1, when lubricating oil needs to be added, the oil pump 7 on the top of the oil storage box 4 is driven to deliver the lubricating oil to the inside of the oil spray ring 5 through the oil inlet hose 6, and the oil is sprayed through multiple oil nozzles 8 surrounding the joints of the robotic arm body 1, thereby lubricating it and making the lubrication effect better.

[0025] refer to Figure 4An arc-shaped oil receiving shell 9 is provided on one side of the oil injection ring 5 at the bottom of the oil injector 8. An installation ring 10 is provided on one side of the arc-shaped oil receiving shell 9. The installation ring 10 fits against the outer wall of the oil injection ring 5. The two sides of the installation ring 10 and the two sides of the outer wall of the oil injection ring 5 are provided with corresponding fixing holes 11. Fixing bolts 12 are provided in the fixing holes 11. More specifically, by installing the arc-shaped oil receiving shell 9 on one side of the oil injection ring 5 at the bottom of the oil injector 8, the arc-shaped oil receiving shell 9 can collect the excess lubricating oil sprayed from the oil injector 8, avoiding lubricating oil dripping and causing pollution. At the same time, by opening the corresponding fixing holes 11 on the outer wall of the installation ring 10 and the oil injection ring 5, and fixing it with fixing bolts 12, it is easier for the staff to disassemble and assemble the arc-shaped oil receiving shell 9, thereby facilitating the internal cleaning.

[0026] refer to Figure 3 and Figure 4 The arc-shaped oil receiving shell 9 is equipped with a filter screen 13 inside, which fits into the inner arc of the arc-shaped oil receiving shell 9. The bottom of the arc-shaped oil receiving shell 9 is also provided with an oil leakage hole, and an oil delivery hose 14 is connected inside the oil leakage hole. The other end of the oil delivery hose 14 is connected to a circulation pump 15 provided on the side wall of the oil storage box 4. More specifically, by setting a filter screen 13 inside the arc-shaped oil receiving shell 9, the filter screen 13 can precipitate and filter excess lubricating oil. After precipitation and filtration, the lubricating oil is transported to the oil storage box 4 for reuse through the action of the oil delivery hose 14 and the circulation pump 15, thereby improving the recycling effect of lubricating oil.

[0027] The implementation principle of a robotic arm joint with a lubrication structure in this application embodiment is as follows: In use, the oil spray ring 5 is fixedly installed on the two inner side walls of the rotating seat 2. When lubricating oil needs to be added, the oil pump 7 at the top of the oil storage box 4 is driven to deliver the lubricating oil to the inside of the oil spray ring 5 through the oil inlet hose 6, and the oil is sprayed through multiple oil spray nozzles 8 surrounding the joint of the robotic arm body 1 to lubricate it. After lubrication, the excess lubricating oil will drip into the arc-shaped oil receiving shell 9, settle inside it, and be filtered by the internal filter screen 13. The settled and filtered lubricating oil is delivered to the oil storage box 4 for reuse by the bottom oil delivery hose 14 and the circulation pump 15, thereby improving the recycling effect of the lubricating oil. When it is necessary to clean the arc-shaped oil receiving shell 9 and the internal filter screen 13, the arc-shaped oil receiving shell 9 can be removed by rotating the fixing bolt 12 in the fixing hole 11 corresponding to the outer wall of the mounting ring 10 and the oil spray ring 5, making it easier for the staff to disassemble and assemble the arc-shaped oil receiving shell 9, thus facilitating the internal cleaning.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
