Milling machine is general to state Milling machine is to carry out the machine tool of milling processing with milling cutter for workpiece. Milling machine excludes can milling plane, groove, gear teeth, thread and spline axle are outside, can still process more complex type surface, efficiency has high planer comparatively, when mechanical production and repair department get extensive application. 2. Hydraulic technology develops tendency Hydraulic technology is that the one of crucial technical, world countries that realize modern transmission and control give great attention to the development of hydraulic industry. Hydraulic pneumatic technology has unique advantage , such as: Hydraulic technology has power weight than is big, volume is little, frequently loud and high, pressure and rate of flow may control sex well, it may be flexible to deliver power , is easy to realize the advantages such as the sport of straight line; Pneumatic transmission has energy saving, free from contamination, low cost and safe reliable, structural simple etc. advantage , and is easy to form automatic control system with microelectronics and electric in technology. Develop tendency mainly to be as follows: 1. Reduce wastage , use energy 2 fully. Leak control 3. Pollute control 4. Defend 5 initiatively. Electromechanical unifinication 6. Hydraulic CAD technical 7. The application of new material and new technology 3. Design content mainly Quantity of production. May use the garden column milling cutter, garden flat and milling cutter of end panel and is various to process the small-sized workpiece of various types into type milling cutter. Designing have selected to form hydraulic element and the basically hydraulic loop of this hydraulic system , have carried out hydraulic systematic stability school nucleus , have drawn hydraulic system to seek , and have carried out the design of hydraulic big jar. Key words milling machine；hydraulic technology；hydraulic system；hydraulic big jar 目 錄 摘要 2 畢業(yè)設(shè)計(jì)任務(wù)書　　　　　　　　　　　　　　　　　　　　　 　　5 第一章 專用銑床液壓系統(tǒng)設(shè)計(jì) 7 1.1 技術(shù)要求 7 1.2 系統(tǒng)功能設(shè)計(jì) 7 1.2.1 工況分析 7 1.2.2 確定主要參數(shù)，繪制工況圖 8 1.2.3 擬定液壓系統(tǒng)原理圖 10 1.2.4 組成液壓系統(tǒng) 10 1.3系統(tǒng)液壓元件、輔件設(shè)計(jì) 12 第二章 專用銑床液壓系統(tǒng)中液壓缸的設(shè)計(jì) 17 2.1 液壓缸主要尺寸的確定 17 2.2 液壓缸的結(jié)構(gòu)設(shè)計(jì) 　 20 致謝 24 參考文獻(xiàn) 25 畢業(yè)設(shè)計(jì)任務(wù)書 一、設(shè)計(jì)課題 專用銑床液壓系統(tǒng)設(shè)計(jì) 二、設(shè)計(jì)依據(jù) 某銑床工作臺(tái)為臥式布置（導(dǎo)軌為水平導(dǎo)軌，其靜、動(dòng)摩擦因數(shù)μs=0.2;μd= 0.1)，擬采用缸筒固定的液壓缸驅(qū)動(dòng)工作臺(tái)，完成工件銑削加工時(shí)的進(jìn)給運(yùn)動(dòng)；工件采用機(jī)械方式夾緊。工作臺(tái)由液壓與電氣配合實(shí)現(xiàn)的自動(dòng)循環(huán)要求為：快進(jìn) —→工進(jìn)—→快退—→停止。工作臺(tái)除了機(jī)動(dòng)外，還能實(shí)現(xiàn)手動(dòng)。銑床工作臺(tái)的運(yùn)動(dòng)參數(shù)和動(dòng)力參數(shù)如表所列。 表　銑床工作臺(tái)的運(yùn)動(dòng)參數(shù)和動(dòng)力參數(shù) 工況 行程 (mm) 速度 (m/s) 時(shí)間 t(s) 運(yùn)動(dòng)部件重力G(N) 銑削負(fù)載Fe(N) 啟動(dòng)、制動(dòng)t(s) 快速 300 0.075 t1 5500 - 0.05 4 工進(jìn) 100 0.016～0.001 t2 9000 6.25～10 快退 400 0.075 t3 - 5.33 三、設(shè)計(jì)任務(wù)及要求 設(shè)計(jì)要求： 設(shè)計(jì)選擇組成該液壓系統(tǒng)的基本液壓回路并說明液壓系統(tǒng)的工作原理，設(shè)計(jì)計(jì)算選擇液壓元件，進(jìn)行液壓系統(tǒng)穩(wěn)定性校核，繪液壓系統(tǒng)圖，設(shè)計(jì)液壓缸，編寫液壓系統(tǒng)設(shè)計(jì)說明書。 設(shè)計(jì)任務(wù)： 1 設(shè)計(jì)說明書一份 2 繪制液壓系統(tǒng)圖（A1） 3 專用銑床示意圖 （A1） 4 液壓缸裝配圖（A1） 5 液壓缸各零件圖（缸體、活塞、活塞桿、缸蓋）
