組合機(jī)床動(dòng)力滑臺(tái)液壓系統(tǒng)的設(shè)計(jì)

1、畢業(yè)設(shè)計(jì)論文1【摘要】本論文主要闡述了組合機(jī)床動(dòng)力滑臺(tái)液壓系統(tǒng)，能實(shí)現(xiàn)的工作循環(huán)是：快速前進(jìn)→工作進(jìn)給→快速退回→原位停止，液壓技術(shù)是機(jī)械設(shè)備中發(fā)展速度最快的技術(shù)之一。特別是近年可與微電子、計(jì)算機(jī)技術(shù)相結(jié)合、使液壓技術(shù)進(jìn)入了一個(gè)新的發(fā)展階段。目前，已廣泛應(yīng)用在工業(yè)各領(lǐng)域。由于近年來微電子、計(jì)算機(jī)技術(shù)的發(fā)展，液壓元器件制造技術(shù)的進(jìn)一步提高，使液壓技術(shù)不僅在作為一種基本的傳統(tǒng)形式上占有重要地位而且以優(yōu)良的靜態(tài)、動(dòng)態(tài)性能成為一種重要的控制手段

2、。面對(duì)我國(guó)經(jīng)濟(jì)近年來的快速發(fā)展，機(jī)械制造工業(yè)的壯大，在國(guó)民經(jīng)濟(jì)中占重要地位的制造業(yè)領(lǐng)域得以健康快速的發(fā)展。制造裝備的改進(jìn)，使得作為制造工業(yè)重要設(shè)備的各類機(jī)加工藝裝備也有了許多新的變化，尤其是孔加工，其在今天的液壓系統(tǒng)的地位越來越重要。本液壓系統(tǒng)的設(shè)計(jì)，除了滿足主機(jī)在動(dòng)作和性能方面規(guī)定的要求外，還必須符合體積小、重量輕、成本低、效率高、結(jié)構(gòu)簡(jiǎn)單、工作可靠、使用和維修方便等一些公認(rèn)的普遍設(shè)計(jì)原則。液壓系統(tǒng)的設(shè)計(jì)主要是根據(jù)已知的條件，來確定液

3、壓工作方案、液壓流量、壓力和液壓泵及其它元件的設(shè)計(jì)。綜上所述，完成整個(gè)設(shè)計(jì)過程需要進(jìn)行一系列艱巨的工作。設(shè)計(jì)者首先應(yīng)樹立正確的設(shè)計(jì)思想，努力掌握先進(jìn)的科學(xué)技術(shù)知識(shí)和科學(xué)的辯證的思想方法。同時(shí)，還要堅(jiān)持理論聯(lián)系實(shí)際，并在實(shí)踐中不斷總結(jié)和積累設(shè)計(jì)經(jīng)驗(yàn)，向有關(guān)領(lǐng)域的科技工作者和從事生產(chǎn)實(shí)踐的工作者學(xué)習(xí)，不斷發(fā)展和創(chuàng)新，才能較好地完成機(jī)械設(shè)計(jì)任務(wù)。關(guān)鍵詞:組合機(jī)床液壓系統(tǒng)液壓缸液壓泵換向閥Abstract:Abstract:ThefaceofC
