摘要
针对快递行业自动化的需求,设计了一种能准确搬运快递件的机械手爪.以搬运手爪的实际结构为原型进行三维建模和有限元分析,得到手爪的总变形和工作应力,并利用拓扑技术对该结构进行改进优化,结果不仅使手爪结构总变形和总应力有所降低,且质量相较于原结构减轻了20%,证明了该方案设计的合理性和可靠性.
Aiming at the demand of automation in express industry,a kind of mechanical gripper which can accurately handle express delivery is designed.Based on the actual structure of the handling gripper as the prototype,the three-dimensional modeling and finite element analysis are carried out to obtain the total deformation and working stress of the gripper.The structure is improved and optimized by using the topological technology.The result not only reduces the total deformation and total stress of the gripper structure,but also reduces the mass by 20%compared with the original structure,which proves the rationality and reliability of the design of the scheme.
