毕业设计说明书PAGE-37-摘要由于我们所学的专业是机械设计制造及其自动化，为了能够体现该专业的优越性，本次设计的主导思想是用电器控制机械加工，使机械和设计紧密地结合起来。此次毕业设计课题是：简易数控铣床的设计。在这次毕业设计中，我一面着手搞好这次毕业设计，一面又有计划地复习前面所学过的基础知识。从而使我对以前的基础知识掌握得更牢固，而且培养了我解决问题的能力。在这次毕业设计中，我紧扣设计题目，查阅有关技术资料，并在老师的指导和帮助下，完成了数控铣床的设计及相关的电器控制。但由于本人能力、水平有限，仍存在着一些错误，希望老师给予批评指正。最后，我在此向在本次设计中付出了辛勤劳动的指导老师表示由衷的谢意。关键词：机械加工；电器；数控铣床AbstractDuetoourmajoriselectromechanicalintegration,inordertobeabletoreflecttheprofessionalsuperiority,thedesignguidingideologyistousetheelectriccontrolmechanicalprocessing,makethemechanicalandelectricalcloselytogether.Inthegraduationdesign,whileIbegindoeswellthisgraduationdesign,thefrontsideandsystematicallyreviewlearnedthebasicknowledge.ThusthebasicknowledgeofbeforeIacquirefirmer,anddevelopedmyabilitytosolveproblems.Inthegraduationdesign,Igrippingdesigntopic,consultrelevanttechnicaldata,andtheteacher'sguidanceandhelp,completedtheCNCmillingmachinedesignandrelevantelectriccontrol.ButbecauseIability,limitedability,stillhassomemistakes,hopetheteachertogiveanimadversioncorrect.Finally,Iamheretointhisdesignworkedhardlaborguideteachersayawordofheartythanks.Keywords:mechanicalprocessing;electric;CNCmillingmachine目录TOC\o"1-3"\u摘要PAGEREF_Toc263857596\hIAbstractPAGEREF_Toc263857597\hII绪论1X52K型数控铣床主传动系统的运动设计PAGEREF_Toc263857598\h11.1主传动系统技术参数的确定PAGEREF_Toc263857599\h11.2主传动系统的方案论证11.2.1主轴变速范围.....................................................................................................11.2.2初步确定传动方案.............................................................................................21.2.3绘制结构图.........................................................................................................21.2.4拟定转速图.........................................................................................................31.2.5齿轮齿数的确定.................................................................................................41.2.6校验齿轮碰齿问题.................................
