摘　　要：为解决O型密封圈与薄壁圆柱壳体装配过程中压缩变形、间隙咬伤等问题,文中设计了一款压装装置。该装置用于封口盖、密封圈和壳体装配。根据零件装配形式,完成气动装置机械结构设计,同时搭建电气回路。并通过数值分析软件完成气缸选型、压装力计算。根据密封圈安装形式设计导向槽,实现胶圈收口。基于波形弹簧完成弹性结构设计,实现壳体上沿与导向槽端面零公差接触,避免密封圈在装配过程中变形、损伤。通过波形弹簧目标函数标定,设置预装力,提高合格率,实现装置优化。To solve the problem of compression deformation and gap bite during the assembly of O-ring seals and thin-walled cylindrical shells,a pressure fitting device is designed.This device is used for assembling sealing caps,sealing rings and shells.According to the assembly form of the parts,the mechanical structure design of the pneumatic device is completed and the electrical circuit is built at the same time.And cylinder selection and press⁃ing force calculation are completed through numerical analysis software.A guide groove is designed according to the installing form of the sealing ring to achieve the closure of the rubber ring.Based on waveform springs,the elas⁃tic structure design is completed to achieve zero contact between the upper edge of the shell and the end face of the guide groove,and to avoide deformation and damage to the sealing ring during assembly.By calibrating the wave⁃form spring objective function,the pre-installation force is set to improve the qualification rate and achieve device optimization.
