图书分类号： 密 级： 毕业设计(论文) 刀具库总装与控制系统设计 DESIGN OF THE TOOL’S ASSEMBLY AND CONTROL SYSTEM 摘要 科学技术不断进步，带动着世界先进制造技术的孕育而生和一步一步的走向成熟，现代制造业非常重要的加工中心也必须更加完善不断发展进步来满足日益增长的需求，对于工件加工的效率高、加工误差很小很多具有很高技术要求的加工，加工中心的每个部件都必须具备相应的高性能。在加工中心装备了刀具库后，刀具的存储能力得到了质的飞跃，机床的作用，工作能力以及工作效率都得到了很大的提升，而且机床在加工过程中各式各样的干扰因素可以被最小化的隔离掉，加工精度会有明显的提升。 用较少的时间换刀、能够准确定位刀具、能够存放很多的刀具、节省空间、不易发生事故都是自动换刀装置的优点。降低速度的设备选择三级圆柱齿轮减速器，它的传动比高，各组成部件紧密依附，承载均匀。电动机要选用经济实惠的；齿轮和轴都需要硬性检测；选取有适量槽数与拨销数的槽轮机构；PLC主要来研究在选刀方面功能。 关键词 数控系统；加工中心；总装与控制 ；刀具库 Abstract Science and technology progress, drives, the worlds advanced manufacturing technology developed and mature, step by step, the modern manufacturing important machining center must also be more perfect development progress to meet the increasing demand, the error of workpiece machining of high efficiency, small lot has the very high technical requirements of processing, processing center of each parts must have corresponding performance. After machining center is equipped with a tool library, tool storage capacity got a qualitative leap, the role of the machine tool, work ability and work efficiency are a lot of ascension, and in the process of the machine tool in processing all kinds of interference factors can be minimized isolation, the machining accuracy will have obvious ascension. Use less time, accurately positioning the knives, can store a lot of knives, save a space, not easy to happen accident are the advantages of automatic tool change device. Reduce the speed of the three levels of cylindrical gears reduction gear was equipment selection, its transmission ratio is high, closely attached to the components, load evenly. Motor to choose economical; Gear and shaft all need hard detection; Selection of adequate slot number and dial the number of pin slot wheel mechanism; PLC is mainly to study the features in terms of choosing tools.
