磨床电气控制系统设计
摘要：本设计的内容主要是（可编程逻辑控制器）进行改造使用的m7120平面磨床的控制部分。进行了全面的思考和分析的第一本次设计，使自己的m7120平面磨床的基本结构，运动情况，加工工艺要求等有一定的了解。该m7120平面磨床主要成分等车身，尾座主轴齿轮箱，齿轮箱，导螺杆，料杆，刀架。进行分析的m7120平面磨床电气控制部分获得它需要完成开门断电功能，主轴电机反向控制功能，刀架的快速遍历功能，冷却泵电动机的控制。然后根据电气控制电路的电路图，可编程控制器的梯形图转化，转化，进行仿真实验用可编程序控制器实验台。作为一个结果的可靠性极高，极其丰富的指令集，易于掌握，操作方便，丰富的内置集成功能，实时特性。因此导致m7120平面磨床完成门外原有的功能特点，而且还具有安装简便，稳定性好，易于使用，扩展能力强等特点。

Abstract：This design's content is mainly (Programmable Logic Controller) makes the transformation using PLC to the M7120 surface grinding machine's control section. I have carried on the overall ponder and the analysis first to this time design, enables itself to the M7120 surface grinding machine's basic structure, the movement situation, the processing technological requirement and so on to have certain understanding. The M7120 surface grinding machine mainly has compositions and so on automobile body, main axle gear box, tailstock gear box, guide screw, feed rod, tool rest and apron. Carries on the analysis to the M7120 surface grinding machine electric control part to obtain it to need to complete opens the door the power failure function, the main axle electric motor to reverse the control function, tool rest's rapid traverse function, the cooling pump electric motor's control. Then according to the electric control electric circuit's circuit diagram, translates PLC the trapezoidal chart, translates, carries on the experiment simulation using the PLC laboratory bench. As a result of the PLC extremely high reliability, the extremely rich set of instructions, easy to grasp, convenient operation, rich built-in integrated function, real-time characteristic. Therefore causes the M7120 surface grinding machine to complete outside the original function characteristic, but also has the installment to be simple, the stability good, easy to service, the expansion ability strongly and so on characteristics.
