鹽城工學院畢業(yè)設計說明書 2009 雙缸柴油機汽缸體鉆削組合機床總體及夾具設計 摘要 柴油機汽缸體為大批量生產的零件 為了提高生產效率 滿足被加工零 件的精度要求及保證加工精度的穩(wěn)定性 本課題設計了一臺用于雙缸柴油機汽 缸體雙面鉆孔的組合機床 本文介紹了該組合機床總體設計和夾具設計的思路 與內容 第一部分是總體設計 首先 進行了總體方案論證 采用單工位雙面 鉆削組合機床 刀具選用高速鋼麻花鉆 并根據切削用量的選擇 計算切削力 切削扭矩及切削功率 確定主軸直徑 外伸尺寸 接桿型號 選擇滑臺 動力 箱等通用部件 再確定動力部件的工作循環(huán)及工作行程 完成機床聯系尺寸的 制定 最后繪制了三圖一卡 第二部分是夾具設計 經過對被加工零件的全面 分析 定位方案采用三面定位 導向采用固定鉆模板可換鉆套導向 夾緊裝置 采用液壓夾緊機構 直接夾壓于工件上 反應快捷 夾壓平穩(wěn)可靠 夾具體為 框架式結構 有良好的剛性 使夾具能長期保持可靠的精度和穩(wěn)定性 該組合 機床不僅能保證鉆孔精度 還能提高加工效率 降低工人的勞動強度 設計的 夾具定位可靠 夾壓穩(wěn)定 操作方便 達到了設計要求 關鍵詞 組合機床 鉆孔 總體設計 夾具設計 鹽城工學院畢業(yè)設計說明書 2009 The overall and jig design of the overall and jig the combined machine tool for drilling the body of two cylinder diesel Abstract The cylinder block of diesel is a product which nedds mass production In order to prove the production efficiency and meet the precision requeste of the components processed and the precision stability this topic design a combined machine tool to be used in the two cylinder diesel engine with both sides drilling holes It introduces the design of overall and jig of this combined machine tool The first part is overall design First it carries out the argumentation of the overall plan adopte the combined machine tool with single location double faces drilling selecte the high speed steel twist drill According to the cutting parameters it calculates the cutting force the cutting torque and the cutting power determined spindle diameter the extend size and the link pole model chose sliding table the power box and so on then determine the operating cycle and the stroke of the power part formulate the relation size of the machine tool Finally it figures out the productivity which satisfies the request The second part is the jig design after analyse the workpiece the location plan adopte three face location the guiding equipment used the fixed drill plate with replaceable drill bush the clamp uses the hydraulic pressure device it directly presses on the workpiece which responds quickly fixes steadily and reliably the jig body utilize the frame structure possess fine rigidity causes the jig to maintain good long term precision This combined machine tool not only guarante the drill hole precision but also enhance the processing efficiency reduce workers labor intensity The jig orients reliably clamps stably operates easily and meets it the design request well Key words Combined machine tool Drill hole Overall design Jig design 鹽城工學院畢業(yè)設計說明書 2009
