CNC3136数控车床电气系统设计 摘 要 数控技术发展飞速的今天，数控技术在现代制造业发挥越来越重要的作用，数控机床是数控制造业的核心，本文主要介绍了对数控车床的电气系统设计的过程。 CNC6136A 是基于华中数控系统HNC-21的基础上设计制造的新一代的数控车床，对其电气系统设计使尤为重要的，其内容包括强电设计、弱点设计、PLC输入输出及接口设计，绘制出整个机床的电气系统原理图等。 本设计给出了整个机床的原理图绘制过程，重点部分模块化，较详细地介绍了各个部分的功能及用途。分为 380V强电回路，控制回路，PLC输入输出控制，主轴驱动模块和进给伺服驱动模块，并介绍了相关的电气知识。 通过本设计说明书可以基本上掌握数控车床的电气原理，以及基本的电气常识，使读者无论是从整体上还是各个模块中都能够了解到数控车床相关的一系列电气知识。 关键词：数控系统；数控车床；主电路；控制电路；PLC控制；电气原理图 ABSTRACT The numberical controls that the technique development fast today, the numberical controls technique at the modern manufacturing industry exertive more and more importance function, numberical control tool machine is number control a manufacturing industry of core, this text mainly introduced logarithms to control the processceed that the electricity system of lather design. CNC6136 As is according to Hua number control the system HNC-21 of the number of the new generation of the foundation top design manufacturing control lather, as to its the electricity system design make is important, its contents includes a strong electricaly design, weakness design, PLC importation output and Interface design, draw the electricity system principle diagram of a the whole tool machine etc.. This principle diagram which designs to the whole tool machine draws process and the point parts of mold piece turn and compared to in detail introduce each function and use of part.Is divided into the 380 Vs strong electricity back track, control back track, the PLC importation outputs a control, the principal axis drives a mold piece and enters to servo drive a mold piece, and introduced related electronic knowledge. Through this design systerm can basically control numberical control the electricity principle of lather, and basic electronic common sense, make the reader regardless can understand numbrical control the lather related series of electricity knowledge from wholely the top still each mold piece.
