电动式钢管接箍打标设备设计毕业论文.doc

徐州工程学院毕业设计论文I摘要为了及时而准确地识别产品的零部件,需要在产品上标以明显的标志或记号。传统的工业标记打印效率低、不美观、稳定性差、废品率高。气动、电动相结合的方式结构简单,成本低,速度快,可控性好。本文就此提出一种全新的电动标记打印新工艺,对其中的关键技术进行了深入的研究,本文所完成的主要工作如下l研究了电动打标机的总体结构和配置。引用国内外先进方法选关键零部件。2采用步进电动机控制打标头的控制技术。采用频率控制的方法,实现了打印头振动频率与电动执行机构移动速度的协调,保证了打印质量。3研究了计算机与PLC、伺服单元的通信及实时控制技术。利用PLC的编程口实现了计算机与PLC的通信。利用数据总线实现了计算机与伺服单元的通信。利用传感器特性实现了PLC控制打印头动与伺服单元控制电动执行机构运动的协调。4研究了打印图形、字符的设计与转换技术。进行图形和文字的编辑,,实现了从生成的文件中提取有用的几何图形信息,并将这些几何图形信息转化成打标机的打印加工程序。研制完成的电动打标机运行平稳,打印效率高,软件使用方便,具有无气体污染,速度快,精度高等优点,达到了预期设计目标。关键词打印标记硬件组成PLC控制技术步进电动机徐州工程学院毕业设计论文IIAbstractForthesakeofidentifyingrapidlyandaccuratelytheProducedparts,peopleusuallymarktheobvioussignormarkontheimportparts.Themethodsforthetraditionalindustrialsmarkingarenotonlyinefficientandunaesthetic,butalsoshortoflongtermstabilityandhighfortherateofwaster.Relatively,becauseofsimpleconstruction,lowprice,wellcontrolledperformance,rapidspeed,themodeofgaspoweredcombiningelectricpoweredisespeciallysuitable.Abrandnewtechniqueforpneumaticmarkingisputforwardinthispaperandtheresearchforthekeytechniqueofpneumaticmarkermadeisthoroughlycarriedout.Themaincontentsinthisdissertationaresummarizedasfollows1Theoverallstructureandconfigureofpneumaticmarkermadearedeveloped.Thekeycomponentsaredesignedandmatchedbythreedimensionaldesignmethod.2Thetechniqueofcooperativecontrolofthreeaxesisdeveloped.Withthemethodoffrequencycontrol,thecooperativecontrolbetweenthevibrationfrequencyofmarkingheadandthespeedofelectricactuatorisrealized,andthemarkingqualityiswonderful.3Thecommunicationandrealtimecontroltechniquebetweencomputerandplcservounitdeveloped.Thecommunicationbetweencomputerandisrealizedbandthecooperativeofdesignandservounitrealizedbydatabus,andthecooperativecontrolbetweenPLCandservounitisdeveloped.4Thetechniqueofgeometricfigureisextractedandautomaticallytransformedintoprogrammerofmarkermademachinetool.Thepneumaticmarkermademachinetoolrunswellwithreliablehardware,whichisprovidedwithsomecharacteristics,suchasnoairpollution,rapidspeed,highprecision.Sotheprospectivedesignaimcanberealized.KeywordsmarkermadehardwarestructurePLCcontroltechniquestepbystepelectromotive徐州工程学院毕业设计论文III徐州工程学院毕业设计论文I目录1绪论.............................................................................................................................................11.1序言......................................................................................................................................11.2打标机的背景及发展意义...................................................................................................11.2.1电动打标机相关技术的发展........................................................................................31.2.2钢管打标系统的开发现状............................................................................................42打标机系统的总体设计.............................................................................................................62.1打标机系统组成及工作原理..............................................................................................62.2打标机的基本功能及主要技术指标...................................................................................73各机构的选择及设计.................................................................................................................93.1机架设计...............................................................................................................................93.2导轨的设计.........................................................................................................................143.2.1导轨的设计要求......................................................................................................143.2.2导轨的设计程序及内容..........................................................................................153.2.3.直线滑动导轨.........................................................................................................153.3滚动轴承的选择.................................................................................................................153.4键的选择和强度校核.........................................................................................................163.5工件的定位(V型块)..................................................................................................173.5.1V型块的相关尺寸计算..............................................................................................183.5.2对定位元件的基本要求..............................................................................................203.5.3曲面和平面组合基准的定位设计..........................................................................203.5.4定位误差的分析与计算..........................................................................................213.6直齿锥齿轮的传动.............................................................................................................244步进电动机的选择计算...........................................................................................................264.1步进电动机的概述.............................................................................................................264.1.1步进电动机的驱动..................................
