1、沈陽(yáng)理工大學(xué)應(yīng)用技術(shù)學(xué)院畢業(yè)設(shè)計(jì)說(shuō)明書(shū)摘要渦噴-7甲Ⅱ級(jí)渦盤(pán)是飛機(jī)發(fā)動(dòng)機(jī)上的重要零件。本論文分析了渦噴-7甲Ⅱ級(jí)渦盤(pán)的結(jié)構(gòu)工藝和材料工藝,設(shè)計(jì)了該零件的工藝路線(xiàn)。確定主要表面的加工方法,劃分了粗加工,半精加工,精加工階段。合理安排了熱處理和檢驗(yàn)等工序,解決了渦盤(pán)精加工中容易產(chǎn)生變形,尺寸精度,表面粗糙度不易保證等問(wèn)題。按照工序集中的原則設(shè)計(jì)機(jī)床加工工序內(nèi)容,采取了加工過(guò)程的質(zhì)量控制措施。為工序65鉆基準(zhǔn)孔和工序100拉榫槽設(shè)計(jì)了專(zhuān)用的鉆床夾具和拉榫槽夾具,采用了完全定位原則的設(shè)計(jì)定位方案,并且進(jìn)行了結(jié)構(gòu)設(shè)計(jì)。作為飛機(jī)“心臟”的航空發(fā)
2、動(dòng)機(jī)技術(shù)已成為一個(gè)國(guó)家科技水平,國(guó)防實(shí)力和綜合國(guó)力的重要標(biāo)志之一。而WP-7甲Ⅱ級(jí)渦盤(pán)又是航空發(fā)動(dòng)機(jī)的重要零件之一。立此題為我的畢設(shè)題目,是對(duì)我機(jī)械設(shè)計(jì)制造專(zhuān)業(yè)方向的知識(shí)實(shí)踐總結(jié)和深化。關(guān)鍵詞:Ⅱ級(jí)渦盤(pán);鉆床夾具;拉榫槽夾具31沈陽(yáng)理工大學(xué)應(yīng)用技術(shù)學(xué)院畢業(yè)設(shè)計(jì)說(shuō)明書(shū)31沈陽(yáng)理工大學(xué)應(yīng)用技術(shù)學(xué)院畢業(yè)設(shè)計(jì)說(shuō)明書(shū)AbstractTurbojet-7armorⅡThelevelturbinediskisintheaircraftengineimportantcomponents.Thepresentpaperhasanalyzedthetu
