回转式数控多工位运输机上料机械手系统设计+CAD图纸
理论研究的基础上，本文对回转式数控多工位运输机上料机械手整体布局进行了设计，上料机械手釆用滚珠丝杠螺母副机构实现升降、凸轮分度器实现分度转向功能，同时采用气动控制手抓机构即吸盘来抓取物料，以此来克服组件分布分散、设备组合不紧凑从而导致的辅助装卸时间过长影响加工效率等缺陷。

Abstract
Transport maachinery is a new machine which came into being with the development ofthe machine mannufacturing industry. In this paper the research about the existing domestic and foreign transporting equipment ,analyze its structure and function,in summarizing the characters of the existing trancport equipment ,based on the design of the rotary CNC mulit-transport aircraft ,transport aircraft using mulit-position into and ut of material feeding program,with the liting of materials can be achieved simultaneousiy rotating the transport of materials and feeding robat ,it can not only improve the transport efficiency,but also compensate for the deefect of interval stop.
ON the basis of theoretical research,this paper design the overall layout of rotary CNC transfer converyor and design the feed and dischargesystem structure and its driving system.Manipulator withball screw has the fuction of lifting and CAM drivider has the fuction of piding.At thesame time,vacuum suction cup gabing materials can overcome thecomponent distribution of scattered and uncompuct equipment combination leading to influence machining efficiency such as secondary defects loading and unloading time is too long .
