【正文】 臥式單面多軸組合鉆床液壓系統(tǒng)集成塊 及其加工工藝的設(shè)計設(shè)計總說明傳統(tǒng)的液壓系統(tǒng)是通過油管道連接，對管道所承受的壓力要求較高，而且容易造成漏油，影響運動的平穩(wěn)性，其運動效率低，論文采用液壓集成式連接代替?zhèn)鹘y(tǒng)的液壓系統(tǒng)，選擇板式液壓元件安裝在集成塊上，將油孔道布置在集成塊體內(nèi)，既縮小了裝置的占用面積，同時還消除了漏油現(xiàn)象，提高液壓系統(tǒng)的穩(wěn)定性。本課題主要針對臥式單面多軸組合鉆床液壓系統(tǒng)的集成塊進(jìn)行設(shè)計，同時借助Solidworks輔助設(shè)計，綜合應(yīng)用各種先進(jìn)的設(shè)計理念完成本次課題的研究。論文第一部分首先根據(jù)技術(shù)參數(shù)，完成液壓系統(tǒng)的工況分析，制定出液壓系統(tǒng)的各個回路，擬定出液壓系統(tǒng)原理；然后確定液壓缸的工作壓力和主要尺寸；最后根據(jù)各工作回路的最大壓力和流量選擇液壓元件，確定出液壓元件的型號和尺寸。第二部分論文對該液壓系統(tǒng)集成塊結(jié)構(gòu)進(jìn)行設(shè)計。首先繪制集成塊單元回路圖，再合理的布置液壓元件，同時借助Solidworks輔助設(shè)計繪制出三維圖、二維視圖，確定各油孔和連接孔號、孔徑與孔深，并根據(jù)使用要求確定詳細(xì)的技術(shù)要求。最后設(shè)計集成塊的加工工藝。根據(jù)集成塊的技術(shù)要求，毛坯材料選擇45號鋼，確定出毛坯余量。其次擬定出加工工藝路線，繪制出加工工藝卡片。本次設(shè)計使用板式液壓閥，將液壓系統(tǒng)集成到幾個一定尺寸的集成塊上，避免了傳統(tǒng)液壓系統(tǒng)的弊端。同時使用Solidworks軟件設(shè)計，將集成塊體內(nèi)的孔道空間位置清楚地展現(xiàn)出來，對實際生產(chǎn)有著一定意義。但是此次設(shè)計也有很多地方的不足，例如沒有考慮到油液流動的速度對油路彎道的沖擊力，和油孔實際加工中的沉孔等工藝孔的設(shè)計，希望能夠在下次設(shè)計中得到更多的改進(jìn)。關(guān)鍵字：液壓系統(tǒng)；集成塊；加工工藝Structure and Process of the Hydraulic Manifold on the HorizontalSingle –sided Multiaxis Combination Drilling MachineDesign DescriptionThe traditional hydraulic system connects through oil pipelines, and has a higher demand for pressure of pipelines. With its easy to lead, unstable and lower efficiency. The design replaces the traditional hydraulic system with integrated system, on which the plate hydraulic ponents installed and the oil duct arranged in the block, which not only shrinks the device space and eliminates the leakage, but also improves the stability of the hydraulic system.The project is mainly focused on horizontal singlesided multiaxis bination drilling machine hydraulic system design, and with the help of Solidworks, pletes the work application of advanced concepts.First part: according to the requirements and the parameters, the analysis of working conditions and the schematic diagram of the hydraulic system are proposed in this paper. The pressure and main dimensions of the hydraulic cylinder are determined. At last, the type and the size of hydraulic valves are selected based on the primary hydraulic cylinder pressure and flow calculation.Second part: the structure of the manifold. The circuit diagram of manifold block unit, a layout of hydraulic ponents and the dimensions of every oil holes which are shown in the 3D map, 2D view in this paper. Finally, the manifold processing. According to the technical requirements of the manifold, 45 steel is selected as the blank material. The blank margin, the processing line, the manufacturing processing card are worked out.The plate hydraulic valves are used in the design to make the hydraulic system integrated into manifold blocks, which can avoid the drawbacks of traditional hydraulic system. With Solidworks software the location of the holes in the manifold block are clearly demonstrated. However, this design also has many disadvantages, for example, the impaction of the oil flow on the block at the oil corner and the sink holes do not take into account, which be improved in the future .Key words: hydraulic system。 manifold。 processing目 錄第1章 緒論 1 1 1第2章 液壓系統(tǒng)的設(shè)計與計算 2 2 2 2 3 4 4 流量和功率 5 7 7 7 7 7 8 9 9 10 11 15第3章 集成塊的設(shè)計 17 17 17 18 19 20 21第4章 集成塊加工工藝的設(shè)計 22 22 22 22 22 23 23 23 24 24 24 25，刀具，量具及其夾具的選擇 26 26 26 26結(jié)論 27參考文獻(xiàn) 28附錄 29致謝 31III 第一章 緒論 第1章 緒論液壓系統(tǒng)是由若干液壓閥有機(jī)的組合在一起，根據(jù)參考文獻(xiàn)[1]可知各液壓系統(tǒng)間的連接方式有：管式連接、板式連接、集成式連接。管式連接時管路交錯，所占空間大，易造成漏油和滲入空氣。板式連接時油管多，易造成縫隙，不易檢查故障，工藝較復(fù)雜。集成式液壓系統(tǒng)（Integrated Hydraulic Manifold SystemIHMS）的出現(xiàn)，從結(jié)構(gòu)上講，使系統(tǒng)結(jié)構(gòu)變的緊湊，減少了管路連接和接頭，增加了系統(tǒng)的柔性，使系統(tǒng)方便控制，利于標(biāo)準(zhǔn)化；從性能上講，減少了系統(tǒng)的泄漏，減少了系統(tǒng)的震動和功率損失，因此，基于集成塊的集成式液壓系統(tǒng)已經(jīng)是液壓系統(tǒng)設(shè)計的趨勢。根據(jù)參考文獻(xiàn)[2]相比較而言，選擇集成式連接有它獨特的優(yōu)點：（1）可利用原有的板式元件組合成各種各樣的液壓回路，完成各種動作的要求；（2）由于液壓塊向空間發(fā)展，縮小了液壓設(shè)備的占用面積；（3）以塊內(nèi)孔道代替管道，簡化了管路連接，便于安裝和管理；（4）縮短了管路，基本消除了漏油現(xiàn)象，提高了液壓系統(tǒng)穩(wěn)定性；（5）如果變更回路，只要更換液壓塊即可，靈活性大，可實現(xiàn)系統(tǒng)標(biāo)準(zhǔn)化，便于成批生產(chǎn)。本課題所研究的是臥式單面多軸組合鉆床液壓系統(tǒng)集成塊及其加工工藝的設(shè)計，同時借助solidworks軟件輔助，完成液壓集成塊的回路及其加工工藝的設(shè)計。國際上利用計算機(jī)進(jìn)行液壓系統(tǒng)和元件輔助設(shè)計工作，開發(fā)出各類液壓CAD軟件數(shù)十種，目前研發(fā)出了具有自動設(shè)計孔道，校核孔道和任意剖視圖等功能的軟件，同時還將人工智能和CAD技術(shù)相結(jié)合用以解決集成塊的元件布局和孔道設(shè)計問題。國內(nèi)液壓CAD技術(shù)研發(fā)起步比較晚，但是已取得很大發(fā)展，目前各大學(xué)府已經(jīng)成功研制出集成塊CAD三維造型技術(shù)，例如大連理工大學(xué)開
