X6130型銑床總體布局及主軸箱設(shè)計(jì)含8張CAD圖,x6130,銑床,總體布局,主軸,設(shè)計(jì),cad 摘 要 本設(shè)計(jì)介紹了銑床及X6130型萬(wàn)能臥式銑床的一些基本知識(shí)，主要對(duì)X6130的主軸變速傳動(dòng)機(jī)構(gòu)和外觀總體布局進(jìn)行了設(shè)計(jì)。主軸變速箱是變速機(jī)構(gòu)實(shí)現(xiàn)的場(chǎng)所，變速箱中的各傳動(dòng)軸上有不同齒數(shù)和模數(shù)的齒輪，它們通過(guò)相互嚙合將前者的速度傳遞給后者，并且由于齒輪參數(shù)的不同而使速度在傳遞過(guò)程中產(chǎn)生變化。X6130型銑床，主軸箱能實(shí)現(xiàn)12級(jí)變速，機(jī)床主電動(dòng)機(jī)功率是4KW，額定轉(zhuǎn)速1440r/min，主軸最高轉(zhuǎn)速1600r/min，最低轉(zhuǎn)速35r/min，機(jī)床的進(jìn)給是通過(guò)升降臺(tái)縱向或者橫向運(yùn)動(dòng)實(shí)現(xiàn)的；本著優(yōu)化、美觀、實(shí)用和不浪費(fèi)的原則，X6130型銑床總體布局合理，外觀簡(jiǎn)潔，床身協(xié)調(diào)；本設(shè)計(jì)還根據(jù)需要對(duì)一些設(shè)計(jì)進(jìn)行了校核，主要是對(duì)主軸箱的傳動(dòng)軸以及軸上的零部件（如齒輪、軸承等）進(jìn)行了驗(yàn)算，這樣就使本設(shè)計(jì)更加合理、實(shí)用。 關(guān)鍵詞：臥式銑床；X6130；主軸變速機(jī)構(gòu)；總體布局 ABSTRACT The article introduces some basic knowledge about X6130-universal horizontal milling machine and milling machine, designs gear shift drive gear and the overall layout of X6130 principal axis. The gear box is the place in which gear shift can be achieved, and in the gear box there are some gears with different modules and teethes, which will transmit speed of the former to the latter by meshing, and because of the different gear parameters speed will change in the process of transmission. The spindle box of X6130 milling machine may achieve 12-level gear shift, the main motor power of machine tools is 4KW, rated speed is 1440r/min, maximum speed is 1600r/min , minimum speed is 35r/min, feed is achieved by vertical or horizontal movement of elevating table. According to the principle of optimization, aesthetic, practical and saving overall layout of X6130 milling machine is reasonable, appearance is concise, and bed is coordinated. In the article transmission shaft of spindle box and some parts on it (such as gears, bearing) are checked so as to make the design more rational and practical. Key words: Horizontal milling machine; X6130; Gear shift drive gear of principal axis; Overall layout. 目 錄 摘要………………………………………………………………………………Ⅰ Abstract………………………………………………………………………… Ⅱ 第1章 緒論……………………………………………………………………1 第2章 X6130臥式銑床………………………………………………………4 2.1 X6130臥式銑床概述………………………………………………………4 2.1.1 X6130型銑床的用途、結(jié)構(gòu)特點(diǎn)及主要數(shù)據(jù)……………………4 2.1.2 銑床主要部分的名稱及用途………………………………………5 2.1.3 臥式銑床的主要結(jié)構(gòu)………………………………………………9 2.2 銑床常用夾具………………………………………………………………9 2.2.1 夾具的概念…………………………………………………………9 2.2.2 夾具的作用…………………………………………………………9 2.2.3 銑床夾具的類型……………………………………………………10 2.2.4 夾具的組成 ………………………………………………………10 2.2.5 典型工件在銑床上的裝夾方式……………………………………10 第3章 運(yùn)動(dòng)設(shè)計(jì)………………………………………………………………13 3.1 X6130型銑床的主軸傳動(dòng)系統(tǒng)…………………………………………13 3.2 確定結(jié)構(gòu)網(wǎng)及結(jié)構(gòu)式轉(zhuǎn)速圖……………………………………………13 3.3 帶傳動(dòng)的計(jì)算及選定……………………………………………………18 3.4 傳動(dòng)軸及軸頸直徑初定…………………………………………………20 3.4.1 軸的概述…………………………………………………………20 3.4.2 傳動(dòng)軸直徑的確定………………………………………………24 3.4.3 主軸軸頸的確定…………………………………………………24 3.5 核算轉(zhuǎn)速誤差……………………………………………………………25 第4章 零部件的機(jī)構(gòu)設(shè)計(jì)…………………………………………………26 4.1 活動(dòng)軸上的軸承結(jié)構(gòu)設(shè)計(jì)………………………………………………26 4.2 軸的結(jié)構(gòu)設(shè)計(jì)……………………………………………………………27 4.3 滑移齒輪的軸向裝置……………………………………………………28 第5章 零件的驗(yàn)算……………………………………………………………30 5.1 直齒圓柱齒輪應(yīng)力的計(jì)算………………………………………………30 5.2 齒輪精度的確定…………………………………………………………32 5.3 傳動(dòng)軸的驗(yàn)算……………………………………………………………32 5.3.1 傳動(dòng)軸上的彎曲載荷……………………………………………32 5.3.2 主軸組件…………………………………………………………35 5.3.3主軸設(shè)計(jì)…………………………………………………………37 5.3.4 輸入軸的設(shè)計(jì)……………………………………………………37 5.4 滾動(dòng)軸承驗(yàn)算……………………………………………………………39 結(jié)論…………………………………………………………………………………40 參考文獻(xiàn)…………………………………………………………………………41 致謝………………………………………………………………………………42 IV
