托架零件工藝工裝設(shè)計(jì)說明書-全文預(yù)覽
【正文】 套的文檔資料。它的技術(shù)水平在很大程度上決定了產(chǎn)品的質(zhì)量和市場(chǎng)的競(jìng)爭(zhēng)力。制造業(yè)是任何一個(gè)發(fā)達(dá)國(guó)家的基礎(chǔ)工業(yè)，是一個(gè)國(guó)家綜合國(guó)力的重要體現(xiàn)。關(guān)鍵詞： 工序 工藝 工步 加工余量 定位方案 夾緊力Abstract: In the production process so that the production target (of raw materials, blank, or assembly of parts, and so on) the quality and quantity of the state direct the process of change is called process, such as blank manufacturing, machining, heat treatment, assembly, have called the process Process. In the course of the development process, it is necessary to determine the process to install the work place and the process needed further work, the process of the processing machine tools and lootives of the feed rate, cutting depth, cutting speed and spindle speed, the process of the fixture, and cutting tools Measuring, and cutting the number and length of the knife away, the final calculation of the basic processes of time, support time and work to serve the time.key words: Process Technology Step Allowance Orientation Program Clamping force引 言工藝工裝畢業(yè)設(shè)計(jì)是在機(jī)械制造工藝學(xué)及機(jī)床夾具等課程的基礎(chǔ)上，進(jìn)行生產(chǎn)實(shí)習(xí)基礎(chǔ)上進(jìn)行的一個(gè)重要環(huán)節(jié)，它要求學(xué)生全面地綜合運(yùn)用本課程及有關(guān)選修課程的理論和實(shí)踐知識(shí)，進(jìn)行零件加工工藝規(guī)程設(shè)計(jì)和機(jī)床夾具設(shè)計(jì)。在制定工藝過程中，要確定各工序的安裝工位和該工序需要的工步，加工該工序的機(jī)車及機(jī)床的進(jìn)給量，切削深度，主軸轉(zhuǎn)速和切削速度，該工序的夾具，刀具及量具，還有走刀次數(shù)和走刀長(zhǎng)度，最后計(jì)算該工序的基本時(shí)間，輔助時(shí)間和工作地服務(wù)時(shí)間。社會(huì)的發(fā)展與變革，是伴隨著勞動(dòng)工具的發(fā)展與變革。夾具工業(yè)是現(xiàn)代工業(yè)的基礎(chǔ)。畢業(yè)設(shè)計(jì)是學(xué)生從學(xué)習(xí)向工作過度的綜合鍛煉，也是一次提高和再學(xué)習(xí)的機(jī)會(huì)。第一章 零件的分析托架是由φ55的圓柱體里面開一個(gè)φ35的孔，由肋板與長(zhǎng)114，寬50的長(zhǎng)方體的板連接而成，上面開有兩個(gè)橢圓孔，托架可用于傳動(dòng)力和運(yùn)動(dòng)。φ55圓柱上下表面，R9螺紋孔表面，橢圓孔表面和橢圓孔內(nèi)表面的尺寸精度也直接影響與各部分之間的接觸精度。毛坯的鑄造方
