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 II Structure and Process of the Hydraulic Manifold on the Horizontal Single –sided Multiaxis Combination Drilling Machine Design Description The 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 .
