数控激光切割机VIP免费

摘要激光切割的适用对象主要是难切割材料，如高强度、高韧性材料以及精密细小和形状复杂的零件，因而数控激光切割在我国制造业中正发挥出巨大的优越性。本文设计了一台单片机控制的数控激光切割机床，主要完成了：机床整体结构设计，Z轴、XY轴的结构设计计算、滚珠丝杠、直线滚动导轨的选择及其强度分析；以步进电机为进给驱动的驱动系统及其传动机构的分析设计计算；以89C51为主控芯片的数控系统硬件电路设计、系统初始化设计及系统软件方案设计和步进电机的控制流程设计。关键词:CNC激光切割机床结构设计ABSTRACTLasercuttingmachinetoolwasusuallyusedforthehard-cuttingmaterial,suchashigh-strengthmaterial,highprecisionductilematerials,andsmartandcomplicatedcomponents.So,CNClasercuttinghasbeenplayinganimportantroleinChina'smanufacturingindustry.ThispaperdescribesthedesignofaSCM-controlledCNClasercuttingmachinetools.Moreattentionwaspaidontheoverallmachinedesign,Zaxis,XYaxisinthedesign,ball-screwandthechoiceoflinearmotionguideandintensityanalysis;thedrivesystemintowhichsteppermotorwasputandtheanalysisofthedrivesystemdesign;89C51chipwasmainlyusedforthedesignofhardwarecircuit,thedesignofsysteminitializationandthedesignofsteppermotor’scontrollingprogram.Keywords:CNC;lasercuttingmachinetools;architecture;design目录摘要......................................................................................................................IABSTRACT...........................................................................................................II目录......................................................................................................................III第一章绪论..........................................................................................................11.1课题背景..................................................................................................11.2课题研究的目的和意义..........................................................................11.3国内外现状..............................................................................................21.4存在的主要问题......................................................................................31.5设计任务..................................................................................................31.6总体设计方案..........................................................................................4第二章机械部分设计..........................................................................................52.1机械部分XY工作台及Z轴的基本结构设计.......................................52.1.1XY工作台设计..............................................................................52.1.2.Z轴随动系统................................................................................52.2滚珠丝杠传动系统的设计计算..............................................................62.2.1滚珠丝杠的选型...........................................................................62.2.2丝杠的校核...................................................................................72.3直线滚动导轨的选型..............................................................................82.4步进电机及其传动机构的确定..............................................................92.4.1步进电机的特点优点...................................................................92.5齿轮传动机构的确定...........................................................
