为了实现对微小环片零件的自动化装配,搭建了自动装配系统.通过4根直线导向轴与4个直线轴承来提高系统的导向精度和刚度.采用直线导轨进行各装配作业模块之间的切换,保证了微小环片零件的自动装配与取出.在环片的装配方向上,螺旋升降机和光栅尺实现环片的位置精度控制.在Lab VIEW编程环境中,采用分层软件架构和模块化控制思想,避免了不必要的数据循环检测与丢失,能够达到环片组件的装配精度要求.控制系统分为系统初始化模块、参数设置模块、装配模块和取出模块,自动装配系统通过各个模块间的相互交流配合完成装配任务.采用本文中自动装配系统装配环片的实验结果表明,环片零件装配的最大位置误差为26μm,垂直度误差为17μm,平均装配时间为75 s/片,可满足环片组件所需的精度要求.
In order to achieve the automatic assembly of the micro ring parts, an automatic assembly system was set up, which improved the guidance precision and rigidity of the system through four linear guide shafts and four linear bearings.A linear guide was used to switch among the assembly work modules, Which ensures the automatic assembly and removal of the tiny ring parts.Limic elevators and grating ruler control the position accuracy of the ring piece in the assembly direction of the ring piece.In the LabVIEW programming environment, the layered software architecture and the modular control idea , To avoid unnecessary data cycle detection and loss, to achieve the ring assembly precision assembly requirements.Control system is divided into system initialization module, the parameter setting module, the assembly module and the removal module, automatic assembly system through the exchange between the various modules The experimental results of assembling the ring with the automatic assembly system in this paper show that the maximum position error of the ring ring assembly is 26μm, the verticality error is 17μm and the average assembly time is 75s / Required accuracy requirements.
