[0002] As the entire manufacturing industry has higher and higher requirements for automation and energy conservation, the application scope of robotic arms is becoming wider and wider, and the demand for robotic arms is also increasing (robotic arms can withstand higher loads, have higher structural stability and light weight, and at the same time need to be made modular for quick assembly).

[0003] At present, the main frame of the manipulator is mostly made of aluminum alloy octagonal pipes and octagonal pipe connectors. Since the appearance of the octagonal pipe connectors is mostly a special-shaped multi-bevel structure, multiple surfaces of some octagonal pipe connectors need to be processed.

[0004] When processing octagonal pipe connectors, workers load the blanks into the processing center of the CNC machine tool, and during the processing, they need to be manually turned over continuously. This not only takes a long time to process and has low production capacity, but also cannot ensure the accuracy and quality of the product. Utility Model Content
