[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-6This utility model provides a technical solution: an anti-pollution sealing robotic arm, including a base 1, on which a bearing seat 2 is fixedly installed. Bearings are rotatably mounted on opposite sides of the bearing seat 2. A rotating shaft is installed inside each bearing. A rotating arm 3 is fixedly installed on the circumference of the rotating shaft. A mechanical claw 4 is fixedly installed on the rotating arm 3. A sealing mechanism 5 for protecting the bearings is provided on the rotating arm 3. The sealing mechanism 5 includes a sealing cover 501, and an installation ring 502 is fixedly installed on the end face of the sealing cover 501. The installation ring 502 is fixedly installed on the rotating arm 3 by multiple bolts 503. By using bolts 503 to quickly install the sealing cover 501, the bearings mounted on the bearing seat 2 are effectively sealed and protected, thus minimizing environmental contamination of the bearings on the bearing seat 2. This contamination could affect the rotation of the bearings, and consequently, the rotation of the rotating arm 3.
[0024] The following is a detailed explanation of its overall setup and function.
[0025] A rotating ring 504 is rotatably mounted on the sealing cover 501. An oil cylinder 510 is housed inside the rotating ring 504. One end of the oil cylinder 510 is connected to a connecting hose 511, and the other end of the connecting hose 511 is connected to a connecting seat 512. A wiping pad 513 is fixedly mounted on the connecting seat 512 and adheres to the bearing. By utilizing the oil cylinder 510, the lubricating oil inside can flow along the connecting hose 511 to the surface of the wiping pad 513 on the connecting seat 512. This allows the rotating ring 504 to rotate while simultaneously driving the connecting seat 512 to rotate, thereby effectively lubricating the bearing on the bearing housing 2.
[0026] A connecting ring 505 is provided on the rotating ring 504. A threaded cylinder 507 is fixedly installed in the middle of the connecting ring 505. A threaded sleeve 508 is threadedly connected inside the threaded cylinder 507. The threaded sleeve 508 is fixedly installed on the circumferential surface of the oil cylinder 510. By using the threaded cylinder 507 and the threaded sleeve 508, the oil cylinder 510 located in the rotating ring 504 can be quickly disassembled and assembled, thereby enabling the quick replacement of the oil cylinder 510 and improving the practicality of the entire robotic arm.
[0027] A limiting ring 509 is fixedly installed on one end face of the threaded sleeve 508, and the limiting ring 509 movably abuts against the threaded cylinder 507. By using the limiting ring 509 on the threaded sleeve 508, the installation position of the threaded sleeve 508 can be restricted.
[0028] Multiple elastic elements, each a spring 506, are provided between the connecting ring 505 and the rotating ring 504. The two ends of each spring 506 are fixedly connected to the rotating ring 504 and the connecting ring 505, respectively. By utilizing the springs 506, during the rotation of the rotating ring 504, the wiping pad 513 on the connecting seat 512 is able to adhere tightly to the bearing under the elastic force of the springs 506, thereby allowing the wiping pad 513 on the connecting seat 512 to better apply lubricating oil to the bearing.
[0029] A sealing ring 514 is provided inside the rotating ring 504, and the sealing ring 514 is fitted onto the circumferential surface of the oil cylinder 510. By using the sealing ring 514, the sealing effect between the rotating ring 504 and the oil cylinder 510 is improved, thereby minimizing the possibility of contaminants seeping into the gap between the rotating ring 504 and the oil cylinder 510 and contaminating the bearing in the sealing cover 501, thus further improving the sealing effect on the bearing.
[0030] A rotating rod 515 is fixedly mounted on the rotating ring 504. By utilizing the rotating rod 515, the rotating ring 504 can be easily driven to rotate.
[0031] Working principle: By utilizing the rotating sleeve on the oil cylinder 510 and the threaded cylinder 507 on the connecting ring 505, the oil cylinder 510 can be quickly installed through the cooperation between the rotating sleeve and the threaded cylinder 507. By using the multiple bolts 503 on the mounting ring 502, the sealing cover 501 can be quickly installed onto the rotating arm 3, thereby providing a sealing and protection effect for the bearing on the bearing housing 2. This minimizes the risk of environmental contamination of the bearing on the bearing housing 2, which could affect the rotation of the bearing and consequently the rotation of the rotating arm 3.
[0032] Next, by using the oil cylinder 510, the lubricating oil inside the oil cylinder 510 can flow along the connecting hose 511 to the surface of the wiping pad 513 on the connecting seat 512. Then, by using the rotating rod 515 on the rotating ring 504, the rotating ring 504 can rotate under the action of the rotating rod 515, thereby driving the wiping pad 513 on the connecting seat 512 to rotate. This allows the wiping pad 513 to apply lubricating oil to the bearing while rotating, thus achieving the effect of lubricating the bearing on the bearing seat 2. Furthermore, by using the spring 506, during the rotation of the rotating ring 504, the wiping pad 513 on the connecting seat 512 can be tightly attached to the bearing under the action of the spring force of the spring 506, thereby allowing the wiping pad 513 on the connecting seat 512 to better apply lubricating oil to the bearing.
