1、JIANGXIAGRICULTURALUNIVERSITY本科畢業(yè)論文（設(shè)計）題目：立式單軸木工鏤銑機學(xué)院：工學(xué)院姓名：王沖學(xué)號：20100978專業(yè)：農(nóng)業(yè)機械化及其自動化年級：農(nóng)機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（見木工刀具）將木料開槽、開榫和加工出成形面等的木工機床。木工銑床分為立式單軸木工銑床、木模銑床和鏤銑機3種。立式單軸木工銑床（見圖）的刀具裝在從固定工作臺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面和導(dǎo)板由手動送進，也可使用導(dǎo)向輥和成形銑夾具進行側(cè)面的成形銑削，還可將工件夾緊在活動工作臺上加工榫頭和端
2、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。工件夾緊在工作臺上,可作縱向、橫向和回轉(zhuǎn)進給。木模銑床主要用于模型加工。鏤銑機的刀具主軸轉(zhuǎn)速很高（達2萬轉(zhuǎn)／分）,工件和靠模（見仿形機床）重疊固定在夾具底板上?？磕＠@工作臺中心的定位銷轉(zhuǎn)動或移動時，銑刀即在工件上銑出相應(yīng)的形狀。工作臺可升降和向前傾斜。20世紀70年代以后，數(shù)控（見數(shù)字控制機床）鏤銑機發(fā)展很快，主要有轉(zhuǎn)塔式和龍門式兩種。前者的工作臺作縱向和橫向移動，將刀具的轉(zhuǎn)塔頭作上下運動。后者的主軸作橫向和上下運動，工作臺作縱向運動。鏤銑機主要用于板料雕刻和成形表面的銑削。23關(guān)鍵詞：傳動；齒輪；CAD
