There is a specific determining blank obtained manufacturing form, the selection of base, process route determination, machining allowance, process dimension and the rough determination cutting specifications and so on. In addition, I design the special fixture for hydraulic pump cover, and made a brief description of the fixture operation. Thanks for the great help given by students to teachers in the design. Key words: Hydraulic Pump Cover。在完成此次設(shè)計(jì)任務(wù)中得到老師及同學(xué)們的大力幫助，在此向他們表示衷心的感謝。具體確定毛坯制造形式獲得，基面的選擇，確定工藝路線，加工余量的確定，工序 尺寸及空白，切削用量的確定。應(yīng)用組合機(jī)床加工大批量零件，快捷高效，生產(chǎn)率高，是機(jī)械加工的發(fā)展方向。 編號(hào) 題目： 液壓泵蓋工藝工裝設(shè)計(jì) 信機(jī) 系 機(jī)械工程及自動(dòng)化 專業(yè) 學(xué) 號(hào)： 學(xué)生姓名： 指導(dǎo)教師： （職稱： 高工 ） （職稱： ） 20xx年 5月 25日 II 摘 要 泵是非常重要的一個(gè)零件，廣泛應(yīng)用于機(jī)械產(chǎn)品，如汽油泵，泵，液壓泵，潛水泵，隔膜泵，動(dòng)力轉(zhuǎn)向泵，雙作用 葉片泵，它的作用是不能被其他成分所取代，所以和泵的選擇是密切相關(guān)的泵蓋作為一個(gè)設(shè)計(jì)的主題，來獲取過程有關(guān)的大量書籍的過程中，最好的設(shè)計(jì)方案的綜合比較與選擇 。 液壓泵蓋是液壓泵重要的零件之一，采用鉆、擴(kuò)、 銑等 傳統(tǒng)工藝 ,不僅效率低 ,而且穩(wěn)定性差 ,精度不易保證 ,制約了生產(chǎn)的發(fā)展。本設(shè)計(jì)主要包括液壓泵蓋的加工工藝過程的設(shè)計(jì)，應(yīng)采取哪些措施存在的主要問題和液壓泵蓋的加工設(shè)計(jì)過程。 此外，這次還給液壓泵蓋進(jìn)行了專用夾具設(shè)計(jì)，以及夾具操作的簡要說明。 關(guān)鍵詞： 液壓泵蓋；工藝；夾具設(shè)計(jì) 全套圖紙，加 153893706 III Abstract Pump is a very important and widely used parts in mechanical products, such as Gasoline pump, variable frequency pump, hydraulic pump, submersible pump, diaphragm pump, power steering pump, double action vane pump, role cannot be replaced by other parts, and therefore I choose the pump cover closely related to the pump as the design theme. In the design process of I refer to related process books material, prehensive parison finally chooses the best design. Hydraulic pump cover is one of the important parts in hydraulic pump. Using the drilling, expanding, milling and other traditional techniques, is not only low efficiency, and poor stability. It’s difficult to ensure the accuracy and restrict the production development. Using a bination of machine parts in large quantities is the development direction of machining, because it’s efficient and high productivity. This design includes the design of the hydraulic pump cover process planning。 Process。 定位誤差分析 .............................................................................................................. 21 鉆削力與夾緊力的計(jì)算 .............................................................................................. 21 夾具設(shè)計(jì)及操作的簡要說明 ...................................................................................... 22 小結(jié) ..................................................................................................................................... 22 5 結(jié)論與展望 ..........................................................................................................
