活塞零件的機(jī)械加工工藝規(guī)程-全文預(yù)覽
【正文】 , in our university for four years life.My design is Bocha 831,003, part map, rough map, fixture assembly, a fixture parts of the map. Machining process with the card and the corresponding fixture designed by the procedures of the process of a card. First of all, we must familiar with the parts, subject to the parts is Bocha 831,003. Bocha understanding of the role, followed in accordance with the nature of parts and ponents in the face of the map on the roughness of rough determine the size and mechanical Jiagongyuliang. According to another location and then we set the benchmark fine first base, established after the benchmark crude, Bocha finalizing the road map process, the enactment of the workpiece clamping programme, to draw fixture assembly.For me personally, I hope that through the curriculum design of their future will be further engaged in the work of adaptive training, in the hope that their design can exercise their own analysis, problem solving, the ability to search information, the work laid for the future A good foundation. Because of limited capacity, there are a lot of design deficiencies, I hope that teachers give guidance.目 錄前言 11 零件的分析 2 活塞的功用、結(jié)構(gòu)特點(diǎn)及工作條件 2 活塞的主要加工表面及技術(shù)要求 32 工藝規(guī)程設(shè)計(jì) 3 活塞的毛坯材料及制造方法 3 定位基準(zhǔn)的選擇 4 制定工藝路線 5 工藝路線方案一 5 工藝路線方案二 5 工藝方案的比較與分析 6 機(jī)械加工余量及工序尺寸 63 專用夾具設(shè)計(jì) 9 設(shè)計(jì)主旨 10 夾具的設(shè)計(jì) 10 定位基準(zhǔn)的選擇 10 切削力及夾緊力的計(jì)算 10 定位誤差分析 11 夾具設(shè)計(jì)及操作的簡要說明 114 結(jié)論 11參考文獻(xiàn) 13前言我國的汽車行業(yè)正在飛速發(fā)展，汽車的動力部分也在不斷改進(jìn)，活塞是汽車動力不可缺少的一部分，它的工作情況會直接影響汽車的運(yùn)行狀態(tài)。了解了撥叉的作用，接下來根據(jù)零件的性質(zhì)和零件圖上各端面的粗糙度確定毛坯的尺寸和機(jī)械加工余量。這是我們在進(jìn)行畢業(yè)設(shè)計(jì)之前對所學(xué)的各科課程一次深入的綜合性總復(fù)習(xí)，也是一次理論聯(lián)系實(shí)際的訓(xùn)練。5．第14～15天，零件圖的繪制。1．第l～2天查資料，熟悉題目階段。題 目：活塞零件的機(jī)械加工工藝規(guī)程及工藝裝備設(shè)計(jì)一、設(shè)計(jì)題目 活塞零件的工藝加工規(guī)程及工藝裝備設(shè)計(jì)二、原始資料(1) 被加工零件的零件圖 1張(2) 生產(chǎn)類型:（中批或大批大量生產(chǎn)）三、上交材料1．繪制零件圖 1張2．毛坯圖 1張3．編制機(jī)械加工工藝過程綜合卡片 1套4．編制機(jī)械加工工藝卡片（僅編
