摘　　要：涉及机械装配工装夹具领域,应用于组件三点机械限位装配,设计一款高效便捷满足批量产品装配一致性要求的气动装置。基于三爪气动卡盘,通过三维建模软件设计一款新型气动装置。通过对组件整体结构装配尺寸设计,满足两组件空间Z轴方向精准限位,同时实现三点均布限位装配模式。通过气动卡盘三爪向心运动,实现对薄壁圆柱壳体三点加持变形,完成壳体内部组件机械限位和装配。通过仿真软件完成气动系统内部传动机构运动学和动力学仿真分析。An efficient and convenient pneumatic device that meets the consistency requirements of batch product assembly is designed,involving the field of mechanical assembly fixtures and being applied to the three-point mechanical limit assembly of components.A new pneumatic device is designed based on a three claw pneumatic chuck using three dimensions modeling software.By designing the assembly dimensions of the overall structure of the component,precise positioning in the Z-axis direction of the space between the two components can be achieved,while a three-point uniformly distributed limiting assembly mode is achieved.Through the centripetal movement of the three claws of the pneumatic chuck,the three-point clamping deformation of the thin-walled cylindrical shell is achieved,the mechanical limit and assembly between the internal components of the shell is completed.And the kinematic and dynamic simulation analysis of the internal transmission mechanism of the pneumatic system is completed through simulation software.
