【正文】 nal into a position loop, controller adjust quantity input signal added to the position control input, the adjustment realize force position. The force and position hybrid control method’s core ideas is different control strategies respectively for position and force directly control, namely through selecting matrix determine the current first contact point position control and force control direction ,and then applied force feedback information and position feedback information respectively in position loop and force loop used for closedloop control, eventually in restricted movement realize control force and position. 【KEYWORDS】Servo ；two axis interpolation；NC workbench；spring.目 錄摘 要 ............................................................III目 錄 ..............................................................V1 引言 ..............................................................12 伺服兩軸插補(bǔ)數(shù)控工作臺(tái)的研究現(xiàn)狀和發(fā)展趨勢(shì) ........................2 研究歷史和現(xiàn)狀 ................................................2 伺服兩軸插補(bǔ)工作臺(tái)的發(fā)展趨勢(shì) ..................................3 伺服兩軸插補(bǔ)數(shù)控工作臺(tái)的研究意義和路線 ........................33 電機(jī)彈簧伺服系統(tǒng)的結(jié)構(gòu) ...........................................5 電機(jī)彈簧伺服系統(tǒng)的模型 .......................................5 電機(jī)彈簧伺服系統(tǒng)的工作過程 ...................................54 機(jī)械系統(tǒng)設(shè)計(jì) ......................................................7 齒輪參數(shù)選定與計(jì)算 ............................................7 選定齒輪精度、材料、齒數(shù)及螺旋角 ...........................7 齒面接觸疲勞強(qiáng)度校核 .......................................7 齒根彎曲疲勞強(qiáng)度校核 .......................................8 幾何尺寸計(jì)算 ...............................................9 等效傳動(dòng)慣量計(jì)算(不計(jì)傳動(dòng)效率) ................................9 等效負(fù)載轉(zhuǎn)矩計(jì)算(以下為折算到電機(jī)軸的轉(zhuǎn)矩) ....................9 滾珠絲杠副的結(jié)構(gòu)類型 .........................................10 滾珠循環(huán)方式 ..............................................10 軸向間隙預(yù)緊方式 ..........................................11 滾珠絲杠副直徑和基本導(dǎo)程系列 ..............................11 滾珠絲杠精度等級(jí)確定 ......................................11 滾珠絲杠副支承形式選擇 ....................................11 滾珠絲杠副的選擇 ..........................................11 滾珠絲杠副校核 ............................................12 滾動(dòng)導(dǎo)軌副的防護(hù) ..........................................12 X 軸滾動(dòng)導(dǎo)軌設(shè)計(jì)計(jì)算 ..........................................125 伺服兩軸插補(bǔ)數(shù)控工作臺(tái)的零件設(shè)計(jì)圖紙解析 .........................13 零件圖紙分析 .................................................13 齒輪的選擇 ................................................13 彈簧尺寸的選擇 ...........................................14 圓盤零件圖 ................................................14 輔助裝置的選擇 ...............................................156 總結(jié) .............................................................16參考文獻(xiàn) ...........................................................18致謝 ...............................................................19附錄 ...............................................................201 引言數(shù)控機(jī)床的出現(xiàn)和發(fā)展，有效的解決了一些高精度、高復(fù)雜性的零件技術(shù)要求。伺服系統(tǒng)是以機(jī)械運(yùn)動(dòng)的驅(qū)動(dòng)設(shè)備，電動(dòng)機(jī)為控制對(duì)象，以控制器為核心，以電力電子功率變換裝置為執(zhí)行機(jī)構(gòu)，在自動(dòng)控制理論的指導(dǎo)下組成的電氣傳動(dòng)自動(dòng)控制系統(tǒng)。目前，最成功且接近實(shí)用的柔順控制策略是力、位混合控制。2 伺服兩軸插補(bǔ)數(shù)控工作臺(tái)的研究現(xiàn)狀和發(fā)展趨勢(shì) 研究歷史和現(xiàn)狀當(dāng)今世界電子技術(shù)迅速發(fā)展，微處理器、微計(jì)算機(jī)在各技術(shù)
