1、32加工中心盘式刀库自动换刀设计说明书PLC编程课题研修设计说明书设计课题：自动换刀加工中心专业班级：学生姓名：学号：指导老师：宁波技师学院电气技术系二零一一年三月32加工中心盘式刀库自动换刀设计说明书摘要90年代以来，数控加工技术得到迅速的普及和发展。加工中心作为新时代数控机床的代表，已在机床领域广泛使用。自动换刀装置作为加工中心最重要的部分之一，它的发展也直接决定了加工中心的发展。本论文完成的是加工中心盘式刀库的传动设计、结构设计以及传动部分的动力设计。这种刀库在数控加工中心上应用非常广泛，其换刀过程简单，换刀时间短，定位精度高；总体结构

2、简单、紧凑，动作准确可靠；维护方便，成本低。本刀库满载装刀20把，采用单环排列方式放置，按就近选刀原则选刀。本次设计中的机械手采用单臂双手式机械手，这种机械手的优点是可以同时完成插刀和拔刀动作，结构简单，换刀时间短。关键词：　加工中心；盘式刀库；机械手；自动换刀装置32加工中心盘式刀库自动换刀设计说明书目录摘要································································1目录···················································
