普通车床CA6140的控制系统设计 摘要 在经济和科技飞速发展的现在，机床产业不断向着高精度、高效率、低成本和智能化发展。然而，普通机床低成本、适应性强、维护方便等特点任使其在短期内有很大需求。CA6140普通车床使用非常广泛，约占车床类总数的65%，可以加工各种零件内外表面，端面和各种内外螺纹。 本文根据CA6140普通车床的技术参数，对C6140普通车床的控制系统和床头箱部分结构进行设计。 控制系统部分，经过控制要求分析和电路分析完成了电气原理图、电气接线图和相应元件的选择，并实现了传统接触器控制的宇龙机电仿真。在此基础上，对CA6140普通车床的控制系统进行PLC改造，提高其控制系统的可靠性，并同样完成宇龙仿真软件的仿真实现。 结构部分，根据已有的技术参数，对CA6140床头箱结构进行分析设计，并利用AUTOCAD软件绘制床头箱结构的二维装配（展开）图和学习CREO2.0软件并绘画床头箱三维图。 关键词：CA6140车床；PLC；控制系统；床头箱 ABSTRACT With the rapid developme
