【正文】 4 Abstract The graduation design is special milling machine for Tiles seam allowance of cylinder body. Special milling machine is based on needs of work, match with a few special parts of cutting tools. The design is mainly their learned knowledge bined with auxiliary materials applied to the design, to consolidate and deepen the knowledge already learned to master the main transmission gearbox design calculations, general procedures and methods spindle design calculations, milling assembly. Reasonably determine the correct actuators and plete the overall layout milling, determine its contact size. Finalize the assembly drawing. Throughout the design process is divided into: the overall program design, the main drive system design, design milling, machine binations. Key Words : special milling machine, the main drive system ,milling tools 5 第一章 總體設(shè)計 方案設(shè)計 過去 ， 采油機汽缸體瓦蓋止口是在 X53K 型立銑上用 50 的棒銑刀加工。此次設(shè)計主要是將自己所 學(xué)的知識結(jié)合輔助材料運用到設(shè)計中，鞏固和深化已學(xué)知識，掌握 主傳動系統(tǒng)中的 減速箱 設(shè)計計算 、主軸設(shè)計計算 的一般步驟和方法， 銑頭裝配。為適應(yīng)現(xiàn)代機械工業(yè)多品種、中小批量生產(chǎn)的需要，擴大夾具的柔性化程度，改變專用夾具的不可拆結(jié)構(gòu)，發(fā)展可調(diào)夾具結(jié)構(gòu)，將是當(dāng)前夾具發(fā)展的主要方向。 ；用于精密車削的高精度三爪自定心卡盤，其定心精度為 5μ m。例如，在銑床上使用電動虎鉗裝夾工件，效率可提高 5倍左右；在車床上使用高速三爪自定心卡盤，可保 證卡爪在試驗轉(zhuǎn)速為 9000r/min 的條件下仍能牢固地夾緊工件，從而使切削速度大幅度提高。目前我國已有夾具零件及部件的國家標(biāo)準(zhǔn)：以及各類通用夾具、組合夾具標(biāo)準(zhǔn)等。國外一些廠家大多采用拉削，但專用止口拉刀的設(shè)計與制造非常困難?？傮w增長趨勢并不明顯，可見，我國臥式銑床市場仍有待開發(fā)。1 提供全套，各專業(yè)畢業(yè)設(shè)計 目 錄 前言 .................................................................................................................................................. 2 摘 要 ............................................................................................................................................... 3 Abstract.............................................................................................................................................. 4 第一章 總體設(shè)計 ............................................................................................................................... 5 方案設(shè)計 ............................................................................................................................... 5 主電機的選擇 ........................................................................................................................ 7 銑削力的計算 ............................................................................................................. 7 三面刃銑刀 ............................................................................................................. 8 主電機的選擇 ............................................................................................................. 8 傳動比的計算 ........................................................................................................................ 9 總傳動比 .................................................................................................................... 9 傳動比的分配 ............................................................................................................. 9 第二章 主傳動系統(tǒng)的設(shè)計 ............................................................................................................... 10 傳動裝 置 ............................................................................................................................. 10 動力及運動參數(shù)計算 ................................................................................................ 10 傳動零件的設(shè)計計算 ................................................................................................ 11 軸的設(shè)計計算 ........................................................................................................... 16 鍵的選用 .................................................................................................................. 24 滾動軸承的選用及計算 ............................................................................................. 24 潤滑及密封 .............................................................................................................. 26 附件的設(shè)計及選擇 .................................................................................................... 26 主傳動軸 ............................................................................................................................. 27 軸承座 .................................................................................................................... 27 軸承的選用 ............................................................................................................. 28 主傳動軸 ................................................................................................................. 28 第三章 銑頭 .................................................................................................................................... 28 刀具選擇 ............................................................................................................................. 28 傳動裝置 ............................................................................................................................ 31 傳動零件 ................................................................................................................. 31 蝸輪蝸桿傳動 ....................................................................................................... 31 人 字齒輪 ............................................................................................................. 35 軸的設(shè)計 ........................................................................................
