【正文】 畢 業(yè) 設 計設計（論文）題目：推動架的工藝規(guī)程及夾具設計 姓 名 岳國晉 學院 （系）機械電子工程系 專 業(yè) 機械設計制造及其自動化 年 級 09級 指 導 教 師 杜鵑 2013 年 6 月 14 日摘 要本設計的內容可分為機械加工工藝規(guī)程設計和機床專用夾具設計兩大部分。首先，通過分析B6065刨床推動架，了解到推動架在B6065刨床加工中的作用。運用機械制造技術及相關課程的一些知識，解決推動架在加工中的定位、加緊以及工藝路線的安排等方面的相關問題，確定相關的工藝尺寸及選擇合適的機床和刀具，保證零件的加工質量。其次，依據(jù)推動架毛坯件和生產(chǎn)綱領的要求及各加工方案的比較，制定出切實可行的推動架加工工藝規(guī)程路線。最后，根據(jù)被加工零件的加工要求，參考機床夾具設計手冊及相關方面的書籍，運用夾具設計的基本原理和方法，擬定夾具設計的方案，設計出高效、省力、經(jīng)濟合理并且能保證加工質量的夾具。夾具設計的主要內容是銑床夾具和鉆床夾具，分別加工Φ50和Φ35端面和Φ16孔。第一套夾具是通過利用一個大端面和一個定位銷與一個擋銷來完成定位，利用浮動壓緊機構對零件進行夾緊；再配合兩個定位塊進行銑端面。有支承板與底面的平行度誤差和中心孔軸線與底面的垂直度誤差。第二套夾具是通過液壓裝置來進行夾緊，通過短心軸進行中心孔定位，定位方式與上一套類似。此夾具存在的誤差與上一套夾具的誤差情況相同。關鍵詞 機械加工、工藝規(guī)程、專用夾具、推動架 27 / 30 ABSTRACTThe design of the content can be divided into a point of order processing machinery and machine tools designed for the two most fixture design. First of all, through the promotion of B6065planer, that promote the B6065 planerprocessing role. Use of machinery manufacturing technology and related programs of knowledge, promoting the solutionprocessing in the position to step up and the line of the arrangement, and so on related issues, establishing the process and choose a suitable size and machine tools, spare parts processing quality assurance . Secondly, the basis for promoting the roughpieces and production and processing requirements of the Programme of the programme, to promote the development of a practical point of orderprocessing line. Finally, in accordance with the requirements of the processing parts processing, machine tool fixture design reference manual and related aspects of the books, use of fixture design of the basic principles and methods, the programme drawn up fixture design, design efficient, effort, economic and reasonable to ensure the quality of processing Fixture. The main content of the fixture is milling fixture and drilling fixture, respectively processing Φ 50 and Φ35 face and Φ 16 hole the first set of fixture is through the use of a large end face and a positioning pin and a blocking pin to plete the positioning, using floating holddown mechanism for clamping parts。 Combined with two locating piece with support plate milling face and underside of the parallelism error and center hole axis and the underside of the perpendicularity error of a second set of fixture is through clamping hydraulic device, through the short mandrel center hole positioning, positioning method and a set of similar this fixture error and a set of fixture error conditions are the same.Key words: Machining, process planning, special fixture, To promote 目 錄摘要……………………………………………… ………………………………….I第1章 引 言………………………………………… ………………………… …1…………………………………………………………2………………………………………………………3……………………………………………3第2章 零件的分析…………………………………………………………………4……………………………… ………… …… ……… ……………4……………… ………………… ………… … ………………4
