專用數(shù)控銑床自動進出料系統(tǒng)設計
摘 要
本次畢業(yè)設計名為專用數(shù)控銑床自動進出料系統(tǒng)設計，從研究數(shù)控銑床加工中心工作臺入手，借鑒國內外先進經(jīng)驗，設計了一個適合與加工中心工作臺匹配的自動進出料裝置，完成具有動作快速、定位準確以及可以長時間連續(xù)作業(yè)等優(yōu)點的自動進出料裝置設計，滿足了生產(chǎn)和設計的需要，主要設計包括一套專用夾具、輸送機構等主要部件。
認真了考慮“實用、安全、經(jīng)濟”等各項因素，進行必要的方案計較后，最終確定最佳方案為專用夾具選用了電動裝置作為夾緊裝置，設計了壓桿及內外壓板進行工件的夾緊、定位。輸送機構選用了機電裝置，采用了步進電機、滾動直線導軌、滾珠絲杠螺母副和聯(lián)軸器等進行工件的自動進出料。
設計主要進行了與加工中心工作臺匹配的輸送機構自動進出料裝置以及專用夾具的結構設計，并進行了分析。論述了采用步進電機、滾動直線導軌、滾珠絲杠螺母副以及電動夾緊裝置的優(yōu)點。詳細介紹了主要部件的結構設計過程及相關的計算校核。另外匯總了有關技術參數(shù)。
