1、JIANGXIAGRICULTURALUNIVERSITY本科畢業(yè)論文（設(shè)計(jì)）題目：立式單軸木工鏤銑機(jī)學(xué)院：工學(xué)院姓名：王沖學(xué)號(hào)：20100978專業(yè)：農(nóng)業(yè)機(jī)械化及其自動(dòng)化年級(jí)：農(nóng)機(jī)101指導(dǎo)教師：林金龍職稱：講師二0一四年五月23摘要木工銑床-用高速旋轉(zhuǎn)的銑刀（見(jiàn)木工刀具）將木料開(kāi)槽、開(kāi)榫和加工出成形面等的木工機(jī)床。木工銑床分為立式單軸木工銑床、木模銑床和鏤銑機(jī)3種。立式單軸木工銑床（見(jiàn)圖）的刀具裝在從固定工作臺(tái)伸出的垂直銑刀軸上，銑刀軸可傾斜和上下調(diào)整。工件緊貼固定工作臺(tái)面和導(dǎo)板由手動(dòng)送進(jìn)，也可使用導(dǎo)向輥
2、和成形銑夾具進(jìn)行側(cè)面的成形銑削，還可將工件夾緊在活動(dòng)工作臺(tái)上加工榫頭和端面。木模銑床的刀軸裝在懸臂前部，可在垂直平面內(nèi)轉(zhuǎn)一角度。懸臂可在立柱上升降。工件夾緊在工作臺(tái)上,可作縱向、橫向和回轉(zhuǎn)進(jìn)給。木模銑床主要用于模型加工。鏤銑機(jī)的刀具主軸轉(zhuǎn)速很高（達(dá)2萬(wàn)轉(zhuǎn)／分）,工件和靠模（見(jiàn)仿形機(jī)床）重疊固定在夾具底板上。靠模繞工作臺(tái)中心的定位銷轉(zhuǎn)動(dòng)或移動(dòng)時(shí)，銑刀即在工件上銑出相應(yīng)的形狀。工作臺(tái)可升降和向前傾斜。20世紀(jì)70年代以后，數(shù)控（見(jiàn)數(shù)字控制機(jī)床）鏤銑機(jī)發(fā)展很快，主要有轉(zhuǎn)塔式和龍門(mén)式兩種。前者的工作臺(tái)作縱向和橫向移動(dòng)
3、，將刀具的轉(zhuǎn)塔頭作上下運(yùn)動(dòng)。后者的主軸作橫向和上下運(yùn)動(dòng)，工作臺(tái)作縱向運(yùn)動(dòng)。鏤銑機(jī)主要用于板料雕刻和成形表面的銑削。23關(guān)鍵詞：傳動(dòng)；齒輪；CADAbstractWoodworkingmilling-cutterrotating(seewoodworkingtool)willbewood,tenonandslotmachinewoodworkingmachineformingsurfaceetc..Woodworkingmillingmachineisdividedintoverticalaxismilling
