專用數(shù)控銑床自動(dòng)進(jìn)出料系統(tǒng)設(shè)計(jì)
摘 要
本次畢業(yè)設(shè)計(jì)名為專用數(shù)控銑床自動(dòng)進(jìn)出料系統(tǒng)設(shè)計(jì)，從研究數(shù)控銑床加工中心工作臺(tái)入手，借鑒國內(nèi)外先進(jìn)經(jīng)驗(yàn)，設(shè)計(jì)了一個(gè)適合與加工中心工作臺(tái)匹配的自動(dòng)進(jìn)出料裝置，完成具有動(dòng)作快速、定位準(zhǔn)確以及可以長時(shí)間連續(xù)作業(yè)等優(yōu)點(diǎn)的自動(dòng)進(jìn)出料裝置設(shè)計(jì)，滿足了生產(chǎn)和設(shè)計(jì)的需要，主要設(shè)計(jì)包括一套專用夾具、輸送機(jī)構(gòu)等主要部件。
認(rèn)真了考慮“實(shí)用、安全、經(jīng)濟(jì)”等各項(xiàng)因素，進(jìn)行必要的方案計(jì)較后，最終確定最佳方案為專用夾具選用了電動(dòng)裝置作為夾緊裝置，設(shè)計(jì)了壓桿及內(nèi)外壓板進(jìn)行工件的夾緊、定位。輸送機(jī)構(gòu)選用了機(jī)電裝置，采用了步進(jìn)電機(jī)、滾動(dòng)直線導(dǎo)軌、滾珠絲杠螺母副和聯(lián)軸器等進(jìn)行工件的自動(dòng)進(jìn)出料。
設(shè)計(jì)主要進(jìn)行了與加工中心工作臺(tái)匹配的輸送機(jī)構(gòu)自動(dòng)進(jìn)出料裝置以及專用夾具的結(jié)構(gòu)設(shè)計(jì)，并進(jìn)行了分析。論述了采用步進(jìn)電機(jī)、滾動(dòng)直線導(dǎo)軌、滾珠絲杠螺母副以及電動(dòng)夾緊裝置的優(yōu)點(diǎn)。詳細(xì)介紹了主要部件的結(jié)構(gòu)設(shè)計(jì)過程及相關(guān)的計(jì)算校核。另外匯總了有關(guān)技術(shù)參數(shù)。
