In response to the pain points of low production efficiency, insufficient job safety, and high labor intensity in the traditional manual material picking mode of CNC gear hobbing machines, this paper conducts research on the design of the loading and unloading manipulator for CNC gear hobbing machines. The paper systematically reviews the development history and industrial application scenarios of robotic arms, clarifying their basic composition and core design content; Through the scheme demonstration and optimization design of the overall structure of the robotic arm, the coordinate form and degree of freedom configuration suitable for the feeding condition of the gear hobbing machine were determined. The scheme planning of the hand clamping mechanism, wrist rotation mechanism, main and auxiliary arm telescopic mechanism, and body rotation mechanism was completed. At the same time, the pneumatic driving mode and corresponding control scheme were selected, and the main technical parameters of the robotic arm were clarified and its motion logic was analyzed. On this basis, fine structural design and 3D modeling of key components of the robotic arm are carried out. Through theoretical calculations, the hand clamping force, wrist and arm driving torque are verified, and pneumatic components are selected reasonably. The connection structure between each component and the body buffer device are designed. This pneumatic material retrieval robot has the characteristics of simple structure, stable operation, and rapid response. It can achieve automatic grasping and transportation of gear hobbing workpieces, effectively improve the automation production level of CNC gear hobbing machines, reduce manual intervention costs, and provide technical support for the intelligent upgrading of gear machining production lines.
