 ABSTRACT
This paper firstly lifting clamp technology development and application, domestic and foreign development and development trend of 50kg crane, through the design scheme based on the determination of design, including selecting the model, determine crane for arm, then to pose crane components of the crane structure design, including holding mechanism, the arm, clamp arm, axle, automatic switch devices and equipment stability analysis and so on design. Adopted the general design method of mechanical design, mechanical design support software AutoCAD and Pro/e, design a lifting clamp device, lift the weight of hoisting speed, 50Kg of 0.1 m/s, operation speed reaches 0.5 m/s, handling objects without jam, fast and convenient, equipment operation is good.
By understanding learn clamp device's working principle, the structure of the crane clamp device classified and analysis, through the analysis to determine crane design scheme clamp device design, transmission device scheme design and analysis equipment stability.
