畢業(yè)設(shè)計(jì)說(shuō)明書(shū)(論文) 作 者: 學(xué) 號(hào)： 系　部: 專 業(yè): 題 目: 轉(zhuǎn)速器盤加工工藝及 關(guān)鍵工序工裝設(shè)計(jì) 指導(dǎo)者： 評(píng)閱者： 2009 年 6 月 畢業(yè)設(shè)計(jì)說(shuō)明書(shū)（論文）中文摘要 工藝規(guī)程是工裝設(shè)計(jì)、制造和確定零件加工方法與加工路線的主要依據(jù)，它對(duì)組織生產(chǎn)、保證產(chǎn)品質(zhì)量、提高勞動(dòng)生產(chǎn)率、降低成本、縮短生產(chǎn)周期及改善勞動(dòng)條件等都有著直接的影響，因此是生產(chǎn)中的關(guān)鍵工作。夾具在機(jī)械加工中起著重要的作用，它直接影響著機(jī)械加工的質(zhì)量，生產(chǎn)效率和成本，因此，夾具設(shè)計(jì)是機(jī)械工藝準(zhǔn)備和施工中的一項(xiàng)重要工作。本文對(duì)機(jī)轉(zhuǎn)速器盤的結(jié)構(gòu)和工藝進(jìn)行了分析，確定了機(jī)械加工工藝路線，制訂出了零件的鑄造工藝方案和機(jī)械加工工藝規(guī)程，并為加工零件上直徑mm的孔設(shè)計(jì)了一套專用鉆床夾具和專用組合機(jī)床。 關(guān)鍵詞 加工工藝 鑄造工藝 工藝規(guī)程 夾具設(shè)計(jì) 畢業(yè)設(shè)計(jì)說(shuō)明書(shū)（論文）外文摘要 Abstract The process is the base of frock design、manufacturing、the method of machining and machining route. Its function is flowing: organizing produce, controlling quality, enhancing productivity, reducing cost, reducing produce periods, improving work conditions, etc. So, the process planning is the core part of produce. Fixture is very important equipment in process of machine manufacturing because it can directly affect the quality of products and productivity and cost. So fixture designing is also a basilica portion in machine process preparative and manufacture. This thesis is about the analysis with the craftwork and the structure of the speed governor tray , make sure the process route, establish the foundry process project and the process planning of the parts, and design a set of appropriative fixture for the bore with diameter 10mm.
