衬套加工工艺与工装设计【摘要】此次设计是对衬套零件的加工工艺和夹具设计，其零件为钢件，具有体积小，零件简单等特点，由于面比孔易加工，在制定工艺规程时，就先加工面，再以面为基准来加工其它，其中各工序夹具都采用专用夹具，对于加工孔此夹具采用旋转螺母手动双向加紧方式加紧，其机构设计简单，方便且能满足要求。关键词：衬套，加工工艺，专用夹具，设计【Abstract】Thedesignisaforkmachiningprocessandfixturedesign,anditscomponentsforcastings,withasmall,complexpartssuchasthecharacteristicsofnoodlethantheholebecauseofeasyprocessing,inthedevelopmentprocessorder,onthefirstnoodleprocessing,andthentonoodleasabenchmarktoprocessother,oneoftheprocessesareusingadedicatedjigfixture,particularlyfortheprocessingofBigheadhole,slotanddrillasmallholeofthefirstslant-holeprocesses,theelectionsideofthepositioningofthetwosalesmethods,andeasytooperatemanualclampingmeansclamping,anditsbodyisdesignedtobesimple,convenientandcanmeettherequirements.Keywords：Dialsthefork,theprocessingcraft,unitclamp,design目录TOC\o"1-2"\h\z\uHYPERLINK\l"_Toc255239644"前言PAGEREF_Toc255239644\h1HYPERLINK\l"_Toc255239645"1零件图工艺性分析PAGEREF_Toc255239645\h2HYPERLINK\l"_Toc255239646"1.1零件结构功用分析：PAGEREF_Toc255239646\h2HYPERLINK\l"_Toc255239647"1.2零件技术条件分析：PAGEREF_Toc255239647\h2HYPERLINK\l"_Toc255239648"1.3零件结构工艺性分析PAGEREF_Toc255239648\h2HYPERLINK\l"_Toc255239649"2毛坯选择PAGEREF_Toc255239649\h3HYPERLINK\l"_Toc255239650"2.1毛坯类型PAGEREF_Toc255239650\h3HYPERLINK\l"_Toc255239651"2.2定位基准选择PAGEREF_Toc255239651\h3HYPERLINK\l"_Toc255239652"2.3.加工阶段的划分说明PAGEREF_Toc255239652\h4HYPERLINK\l"_Toc255239653"3机加工工艺路线确定PAGEREF_Toc255239653\h5HYPERLINK\l"_Toc255239654"3.1加工方法分析确定PAGEREF_Toc255239654\h5HYPERLINK\l"_Toc255239655"3.2加工顺序的安排PAGEREF_Toc255239655\h6HYPERLINK\l"_Toc255239656"3.3机械加工余量的确定PAGEREF_Toc255239656\h7HYPERLINK\l"_Toc255239657"3.4选择各工序的夹具，量具PAGEREF_Toc255239657\h8HYPERLINK\l"_Toc255239658"3.5加工阶段的划分说明PAGEREF_Toc255239658\h8HYPERLINK\l"_Toc255239659"4.工序尺寸及其公差确定PAGEREF_Toc255239659\h9HYPERLINK\l"_Toc255239660"5.设备及其工艺装备确定PAGEREF_Toc255239660\h10HYPERL
