M7130B 平面磨床夾具的設(shè)計(jì)畢業(yè)論文.doc

河南機(jī)電高等?？茖W(xué)校畢業(yè)設(shè)計(jì)論文論文題目：M7130B平面磨床夾具的設(shè)計(jì)摘要本次畢業(yè)設(shè)計(jì)主要設(shè)計(jì)M7130齒條線平面磨床夾具，此夾具的優(yōu)點(diǎn)是磨削精度高，能夠進(jìn)行不同零件的加工，即能加工各種柱形面有能加工各種平面工件，其應(yīng)用范圍非常廣泛。這種夾具主要是利用磨頭的上下運(yùn)動(dòng)和砂輪的圓周面進(jìn)行磨削，砂輪的轉(zhuǎn)速較高，圓周離心力也較大，當(dāng)砂輪與工件的表面接觸時(shí)，會(huì)瞬時(shí)磨出火花。本次設(shè)計(jì)的零件既為圓柱形工件，要求在圓柱面上利用M7130齒條線平面磨床磨出一個(gè)扇形面，其加工工序分為：首先在砂輪上先粗銑一個(gè)扇形槽，然后使扇形槽砂輪以一定的轉(zhuǎn)速與圓柱形工件的表面接觸，最后利用砂輪磨削工件。這樣就可以加工出所需要形狀的工件。總之通過本次設(shè)計(jì)，使我了解了M7130齒條線平面磨床夾具的組成部分及各部分所起的作用，從而使我明白了次家具的工作原理。關(guān)鍵字：夾具、磨削精度、工序AbstractThisgraduationdesignsalineofthemaindesignM7130flatsurfacegrindingmachinetongs,theadvantageofthistongsistowhettoparetheaccuracyhigh,cancarryondifferentsparepartsprocess,canprocessvariouspillarformtofaceitcanprocessvariousflatsurfaceworkpiece,itsapplicationisveryextensive.Thiskindoftongsmainlyistopandbottomsportandthecircumferenceoftheemerywheelsthatmakesuseoftowhettheheadtofacetocarryonwhettopare,theemerywheelbecomesoonhigher,thecircumferenceleavesthementalexertiontoalsocomparegreatly,bethesurfacecontactoftheemerywheelandtheworkpiece,willwhetasparkinamoment.Asparepartsfordesignsinceisthecylinderformworkpiece,requesttofaceinthecylinderupmakeuseofalineoftheM7130flatsurfacegrindingmachinetowhetafan-shapedsideof,itprocessestheworkprefacetoisdividedinto:Firstafan-shapedslotoffirstthickontheemerywheel,thenmakefan-shapedslotemerywheelwithcertainlyturnsoonwiththesurfacecontactofthecylinderformworkpiece,makeuseoftheemerywheeltowhettoparetheworkpiecefinally.Canprocessthustheworkpieceofthedemandshape.Infinepassadesign,makemeunderstandalineoftheM7130flatsurfacegrindingmachinetongstoconstitutethepartofandeachfunctionthatpartrise,thusmakemeunderstandtheworkprincipleofafurniture.Keywords:Tongs,whettoparetheaccuracy,目錄1緒論12夾具的簡介22.1夾具的功用、組成和分類22.2夾具設(shè)計(jì)的特點(diǎn)和基本要求42.2.1夾具設(shè)計(jì)的特點(diǎn)42.2.2夾具設(shè)計(jì)的基本要求42.3工件在夾具中的定位62.3.1工件定位的基本原理62.3.2夾緊裝置的組成72.3.3夾緊裝置的基本要求72.3.4夾緊力的確定82.4基本夾緊機(jī)構(gòu)選擇和應(yīng)用102.5夾緊的動(dòng)力系統(tǒng)112.5.1氣動(dòng)夾緊系統(tǒng)的組成和特點(diǎn)112.6夾具的其它裝置132.6.1對(duì)刀裝置的基本結(jié)構(gòu)132.6.2對(duì)刀裝置位置尺寸的確定132.7分度裝置132.7.1分度裝置的基本形式及定義132.7.2分度裝
