CA6132普通车床的数控化改造作者：班级：指导老师：摘要随着现代科技和社会生产水平的不断提高，零件的精度要求越高，要求用于零件加工的机床有更高的精度和自动化。考虑到机床的生产能力和成本问题，以旧车床为基础，通过数控化改造提高机床的占有率是一条节约资金而又快速有效的方法。本文以CA6132作为研究对象，主要研究内容如下。本文对CA6132普通车床的数控化改造进行了深入研究，包括对数控车床结构的分析、数控车床的改造方案、主传动系统的设计、主轴的形状结构的设计与计算、主电动机的选择、进给伺服电机的选用、滚珠丝杆的计算与选用。根据机械、动力学原理，重新设计了车床的主传动系统，使车床实现变频无级调速。结合车床工作条件加工质量，合理选择滚珠丝杆、齿轮和伺服电机。通过以上的设计即可实现数控车床的改造，实现要求的技术参数。关键词：机床占有率数控化改造伺服电机主传动滚珠丝杆NumericalcontrolinnovationofCA6132commonlatheAbstract：Withthecontinuousimprovementofmodernscienceandtechnologyandthelevelofsocialproduction,thehighertheaccuracyoftheparts,therequirementsforthemachinetoolhasahigherprecisionofpartsprocessingandautomation.ConsideringMachinetoolproductioncapacityandcostintoconsideration,improvingmachinetoolˊsharebynumericalcontroltransformationisanefficientandquickway.Inthispaper,theCA6132ordinarylathenumericalcontroltransformationwasstudied.Thatincludestheanalysisofthenumericalcontrollathestructure,theretrofitschemeofnumericalcontrollathe,themaindrivesystemdesign,theshapeofthespindlestructuredesignandcalculation,thechoiceofmainmotor,feedservomotorselection,calculationandselectionofballscrew.ThemaindrivesystemofmachinetoolwasredesignedAccordingtotheprincipleofmachineryanddynamics,makingmakesthelatherealizefrequencyconversionsteplessspeedregulation.Combinedlatheprocessingqualityofworkingconditions,choosetheballscrew,gear,andservomotor.DesignofCNClathecanberealizedthroughtheabovereform,realizingtechnicalparametersasrequired.Keywords:machinetoolˊsharenumericalcontroltransformationservomotor目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc357249208"第1章绪论PAGEREF_Toc357249208\h1HYPERLINK\l"_Toc357249209"1.1数控技术与数控机床PAGEREF_Toc357249209\h1HYPERLINK\l"_Toc357249210"1.2数控化改造的背景PAGEREF_Toc357249210\h1HYPERLINK\l"_Toc357249211"1.3数控化改造的优点PAGEREF_Toc357249211\h2HYPERLINK\l"_Toc357249212"1.4普通车床数控化改造的现状PAGEREF_Toc357249212\h3HYPERLINK\l"_Toc357249213"1.4.1数控化改造国内外发展现状PAGEREF_Toc357249213\h3HYPERLINK\l"_Toc357249214"1.4.2普通机床数控化改造的趋势PAGEREF_Toc3572
