【正文】 畢業設計（論文）摘要作為現代機械設備實現傳動與控制的重要技術手段，液壓技術在國民經濟，液壓傳動具有其獨特的技術優勢，其應用領域幾乎囊括了國民經濟各工業部門。 本文根據數控銑床的用途﹑特點和要求，利用液壓傳動的基本原理，擬定出合理的液壓系統圖，再經過必要的計算來確定液壓系統的參數，然后按照這些參數來選用液壓元件的規格和進行系統的結構設計。數控銑床的液壓系統，外形新穎美觀，動力系統采用液壓系統，結構簡單、緊湊、動作靈敏可靠。 本文通過對數控銑床的工況分析, 給出了對于一般夾緊裝置分析的方法, 對于提高制造質量、實際生產具有一定的指導意義。 關鍵詞：現代機械；數控銑床；夾緊裝置；液壓系統設計畢業設計（論文）IABSTRACTAs a modern machinery equipment realization transmission and control of important technical means, hydraulic technology in the field of national economy has been widely used with other transmission way. Compared with its unique, hydraulic transmission technology advantage, its application field almost include the national economic each industrial sectors.This article according to the usage, characteristics and requirements of the purposes of CNC milling machine uses the basic principle of hydraulic transmission, draws up a reasonable hydraulic system and undergoes the necessary calculation to determine the parameters of hydraulic system which determine to choose hydraulic ponents and system structure of the specification. The hydraulic system of CNC milling machine is new and original beautiful, the driving force system adopts hydraulic pressure system that makes the structure simple and pact, the action quick and reliable. This paper analyzed the operation condition of the CNC milling machine, and gives the analysis for average clamping device to improve the method, manufacturing quality, the actual production has certain directive significance Key words：Modern machinery；CNC milling machine；Clamping device；Hydraulic system design 畢業設計（論文）II目錄摘要 ............................................................................................................................................................IABSTRACT.............................................................................................................................................II目錄 .........................................................................................................................................................III1 液壓傳動的發展狀況以及優缺點 ........................................................................................................1 國內液壓傳動的發展狀況 .....................................................1 國外液壓傳動的發展狀況 .....................................................1 液壓傳動的優缺點 ...........................................................1 液壓傳動有以下一些優點 ...................................................................................................1 液壓傳動的缺點 ...................................................................................................................22 液壓系統的設計 ....................................................................................................................................3 設計要求 .............................................................................................................................................3 工況分析 ....................................................................3Ⅰ工位夾緊缸的負載計算 ....................................................................................................3 Ⅱ工位夾緊缸的負載計算 ..................................................................................................4 液壓系統主要參數的確定 .....................................................6 系統工作壓力 的確定 .....................................................................................................61p 液壓執行器主要結構參數的計算 ................................................7Ⅰ工位夾緊缸主要結構參數的確定 ......................................................................................7 Ⅱ工位夾緊缸主要結構參數的確定 .....................................................................................8 液壓缸工作循環中各階段的各項參數 .................................................................................83 液壓系統原理圖的擬定和方案論證 ..................................................................................................10 油路循環方式的分析和選擇 ...................................................10 調速方案的分析和選擇 .......................................................10 液壓動力源的分析與選擇 .....................................................11 液壓回路的分析、選擇與合成 .................................................12 液壓原理圖的擬定與設計 .....................................................124 液壓元件的計算和選擇 ......................................................................................................................14 液壓泵的確定 ..............................................................14 閥類的選擇 ................................................................17 選擇依據 ............................................................................................................................17 選擇閥類元件應注意的問題 ............................................................................................17 液壓附件的計算和選擇 ......................................................18 確定管件的尺寸 ................................................................................................................18 確定油箱容積 ....................................................................................................................195 估算液壓系統性能 ..............................................................................................................................21 液壓系統壓力損失驗算 .......................................................21畢業設計（論文）III 系統的發熱和溫升 ..........................................................226 結論 ......................................................................................................................................................25致謝 .........................................................................................................................................................26參考文獻 .......................................................................
