数控枪钻机床总体及钻削系统设计大学学位论文.docVIP

数控枪钻机床-总体及钻削系统设计 数控枪钻技术广泛应用于国防工业、石油采掘、航空航天、机床、汽车等行业。但钻削加工固有难题是：排屑难，导热性差，刀具振动、易折断等。因此高效、高精度的钻削加工机床是国内外机床厂争相研究的方向之一。如大连机床集团生产的主油道孔、连杆孔、缸体斜油道孔等钻削加工机床，将钻削钴削与数控技术有机的结合起来形成高精度、高效率的钻削加工机床，成为国内钻削加工技术的排头兵。 本文主要针对加工，设计一种经济型专用数控枪钻加工机床。将钻削加工技术与经济型数控系统结合，形成结构简单，柔性好，换型方便的实用型专用机床。论文论述了机床机械与电气方案的确定，重点探讨了提高钻削钻削稳定性的方法及刀具的选用。另外针对各种不同形式的数控系统，选择了相对比PLC控制方式效率更髙，比标准数控系统价格更便宜的经济型数控系统一德国的丁公司的IADRAMAT系统。该系统是一种紧凑型、模块化二/四轴交流伺服数控系统，可直接驱动DKC完成伺服电机的精确定位运行。同时本文还介绍了伺服电机的选择，机床电气的硬件电路的设计、电器元件的选择。 文中重点介绍了该机床的设计思路，通过对机械系统与电气控制系统的设计与选用，为孔的加工做出了有重要实际意义的探索。 关键词：钻削加工；枪钻机床；经济型数控系统 CNC gun drill machine - overall and drilling system design ABSTRACT CNC gun drill technology is widely applied in national defense industry, oil extraction, aerospace, machine tools, automotive industries. But drilling inherent problem is: scraps discharge difficult, thermal conductivity is poor, tool vibration, easy broken, etc. Therefore efficiency, high precision drilling machine is domestic and international research direction of the machine tool plant scramble. Such as dalian machine group production main oil tao hole, connecting holes, cylinder inclined oil drilling hole and tao drilling machine, cutting and numerical control (nc) technology cobalt organic combine forming high precision, high efficiency of drilling machine, become domestic drilling technology platoon guide. This article mainly aims at processing, design a cost-effective special nc process machine gun drill. Will drilling technology and economical nc system combined to form, simple in structure, convenient HuanXing flexible, practical special machine. This paper discusses the mechanical and electrical machine, the scheme determination of mainly discusses how to improve the stability of drilling drilling methods and tools to choose. In addition to various kinds of different forms of CNC system, chose relatively than the PLC control way more than standard, high efficiency of CNC system cheaper prices of economical nc system - a German butyl c
