1、粗加工論文|后鋼板彈簧吊耳加工工藝及夾具設(shè)計(jì)    size=6后鋼板彈簧吊耳加工工藝及夾具設(shè)計(jì)/sizesize=1url=font=宋體size=3本次設(shè)計(jì)是對(duì)后鋼板彈簧吊耳零件的加工工藝規(guī)程及一些工序的專用夾具設(shè)計(jì)。后鋼板彈簧吊零件的主要加工表面是平面及孔。由加工工藝原則可知，保證平面的加工精度要比保證孔的加工精度容易。所以本設(shè)計(jì)遵循先面后孔的原則。并將孔與平面的加工明確劃分成粗加工和精加工階段以保證加工精度?；鶞?zhǔn)選擇以后鋼板彈簧吊耳大外圓端面作為粗基準(zhǔn)，以后鋼板彈簧吊耳大外圓端面與兩個(gè)工藝孔作為精基準(zhǔn)。主要加工工序安排是先以后鋼板彈簧吊耳大外圓端

2、面互為基準(zhǔn)加工出端面，再以端面定位加工出工藝孔。在后續(xù)工序中除個(gè)別工序外均用端面和工藝孔定位加工其他孔與平面。整個(gè)加工過(guò)程均選用組合機(jī)床。/size/fontfont=楷體_gb2312font=timesnewromansize=3/size/font/fontfont=楷體_gb2312font=timesnewromansize=3/size/font/fontbfont=黑體size=14pt關(guān)鍵詞/size/font/bbsize=15ptfont=timesnewroman/font/size/bsize=3font=宋體后鋼板彈簧吊耳，加工工藝，專用夾具/fontbsize=15
