I can comprehensive use of mechanical manufacturing technology and other basic curriculum of basic theory and method, in order to be able to complete the turbine speed reducer machining technology and drilling machine fixture design task, the integrated use of knowledge, and apply the correct design method, and developed a turbine speed reducer of the machining process planning. Combine craft design content, skilled in the application process calculation method, the relevant process the content analysis of the correct design and the computation, such as process parameters, cutting force and cutting power, cutting speed, positioning error, clamping force, etc. Through the turbine speed reducer to the processing technology of the determination of the route, the parts processing to the underside as the benchmark is reasonable, the processing technology solutions to meet the basic requirements of basic selection coarse and fine basic selection of the four principles. This fixture for drilling machine use special jig, this fixture is characteristic of the targeted, compact construction, simple operation, high productivity. In this design, the design of the machine tool fixtures meet fixture basic requirements of the overall design, fully guarantee the quality of parts processing, has the high production efficiency and lower cost of manufacture and good structure technology .Key words: Machining; Process specification; Special fixture; Turbine gear unit housing目 錄摘 要IAbstractII第1章 緒論11.1 渦輪減速器箱體綜述11.2 渦輪減速器箱體國(guó)內(nèi)外發(fā)展概況21.2.1 渦輪減速器箱體機(jī)械加工工藝發(fā)展概況21.2.2 渦輪減速器箱體夾具發(fā)展概況3第2章 零件的機(jī)械加工工藝規(guī)程設(shè)計(jì)52.1 渦輪減速器箱體的工藝分析52.1.1 渦輪減速器箱體的作用52.1.2 渦輪減速器箱體的工藝分析52.2 選擇毛坯62.3 確定鑄件機(jī)械加工余量、毛坯尺寸和公差62.4 設(shè)計(jì)毛坯圖72.4.1 確定圓角半徑72.4.2 確定毛坯的熱處理方式72.5 機(jī)械加工工藝路線的制訂92.5.1 選擇定位基準(zhǔn)92.5.2 制訂工藝路線102.5.3 加工工藝過程的分析132.5.4 選擇加工設(shè)備與工藝裝備132.5.5 確定工序尺寸142.5.6 確定切削用量及基本時(shí)間15第3章機(jī)床專用夾具的設(shè)計(jì)353.1 確定設(shè)計(jì)任務(wù)、明確加工要求353.2 定位方案的確定353.3 夾緊機(jī)構(gòu)的設(shè)計(jì)353.4 切削力和夾緊力的計(jì)算353.5 定位誤差的分析與計(jì)算363.5.1 定位元件尺寸及公差確定373.5.2 定位誤差計(jì)算373.6 夾具體的設(shè)計(jì)373.7 夾具與機(jī)床連接元件的選擇383.8 夾具的使用說明383.9 夾具的結(jié)構(gòu)特點(diǎn)39結(jié) 論40致 謝41參考文獻(xiàn)4244
