轉(zhuǎn)速器盤零件的機械加工工藝規(guī)程及工藝裝備設(shè)計-全文預(yù)覽
【正文】 g 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 which is used for the diesel engine, 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 9mm. Key Words： Group technology。本文對 轉(zhuǎn)速器盤的結(jié)構(gòu)和工藝進行了分析，確定了機械加工工藝路線，制訂出了零件的鑄造工藝方案和機械加工工藝規(guī)程，并為加工零件上直徑 Φ 9H8mm 的孔設(shè)計了一套專用鉆床夾具。夾具在機械加工 中 起著重要的作用，它直接影響著機械加工的質(zhì)量，生產(chǎn)效率和成本，因此 ， 夾具設(shè)計是機械工藝準(zhǔn)備和施工中的一項重要工作。 我可以將壓縮包送給你。 Fixture design 4 目 錄 1 零件的工藝分析及生產(chǎn)類型的確定 ...................... 1 零件的作用 ..................................... 1 零件的工藝分析 ................................. 2 零件的生產(chǎn)類型 ................................. 2 2 選擇毛坯、確定毛坯尺寸、繪制毛坯簡圖 ................ 2 毛坯的選擇 ..................................... 2 確定機械加工余量和公差 .......................... 2 設(shè)計及繪制毛坯圖 ............................... 3 3 選擇加工方法，制定工藝路線 ......................... 3 定位基準(zhǔn)的選擇 ................................. 3 零件表面加工方法的選擇 .......................... 4 制訂工藝路線 ................................... 4 4 工序設(shè)計 .......................................... 5 Φ9mm 孔 ........................................ 5 確定切削用量及基本工時（只介紹題目給出的工序） ... 6 5 夾具設(shè)計 .......................................... 7 定位方案 ........................................ 7 夾緊機構(gòu) ........................................ 7 導(dǎo)向裝置 ........................................ 8 夾具體 ......................................... 8 6 方案綜合評價與結(jié)論 .................................. 8 7 體會與展望 .......................................... 8 8 參考文獻 ....
