XK5040主传动系统及控制系统设计.doc

摘 要 在现代化的工业生产设备中，有大量的数字量及模拟量的控制装置（例如电机的起停，电磁阀的开闭，产品的计数、温度、压力、流量的设定与控制等），采用可编程序控制器（PLC）来解决工业现场中的这些自动控制问题已成为最有效的工具之一。 XK5040立式铣床主运动系统的设计：首先分析立式铣床的加工特点和加工要求，确定其主参数（包括运动和动力参数）；再根据主参数和设计要求进行主运动系统机械结构设计及校核（其中主运动系统采用有级变速实现动力传递）；使其达到更高的加工精度、加工效率和更小的能源消耗的目的。 XK5040铣床电气控制线路设计为可编程控制器控制。首先通过对XK5040型立式铣床的电气控制原理进行分析，然后确定输入点和输出点等，画出接线图和其梯形图。再在程序输入机床后进行调试，实现了自动化控制，从而可以减少维护、维修的工作量，提高了整个电气控制系统的工作性能。 关键词：立式数控铣床； 主传动系统； 电气控制； PLC  Abstract In modern industrial production equipment, digital and analog control devices (such as the motor starts and stops, the solenoid valve opening and closing of the count, temperature, pressure, flow rate setting and control, etc.), the use of programmable logic controller (PLC) to solve automatic control problems in the industrial field has become one of the most effective tool.The XK5040 vertical milling machine motion system design: First analysis of vertical milling machine processing characteristics and processing requirements, determine the main parameters (including the movement and power parameters); main parameters and design requirements for the mechanical structure of the main motion system design and school nuclear (including the main movement systems have variable speed and power transmission); to achieve higher machining accuracy and processing efficiency, and smaller energy consumption purposes.The XK5040 milling electrical control circuit design to control the programmable controller. The first principle of the right the XK5040 type vertical milling machine, electrical control, and then determine the input and output points, draw a wiring diagram and ladder. After the program into the machine tool for debugging, automated control, which can reduce the workload of maintenance, repair, improve the performance of the entire electrical control system. Keywords: CNC vertical milling machine; main drive system; electrical control; PLC  目 录 摘 要 I Abstract II 第1章 绪 论 1 1.1 设计的选题意义 1 1.2 设计的主要内容 1 第2章 数控铣床及主传动系统简介 1 2.1 数控铣床
