                                                    安陽機床的伺服系統有哪些特點
                                                    作者:    發布于:2014-10-11 09:52:02    文字:【】【】【

                                                        安陽機床的伺服系統是安陽機床的重要組成部分,包括進給驅動、主軸驅動,用于實現安陽機床的進給伺服控制和主軸伺服控制。伺服系統的作用是把來自數控裝置的運動指令信息,經功率放大、整形處理后,轉換成機床執行部件的直線位移或角位移運動,驅動機床移動部件的運動,使工作臺和主軸按規定的軌跡運動,加工出符合要求的產品。它的伺服精度和動態響應是影響安陽機床加工精度、表面質量和生產率的重要因素之一。

                                                        由于伺服系統是安陽機床的最后環節,其性能將直接影響安陽機床的精度和速度等技術指標,因此,對安陽機床的伺服驅動裝置,要求具有良好的快速反應性能,準確而靈敏地跟蹤數控裝置發出的數字指令信號,并能忠實地執行來自數控裝置的指令,提高系統的動態跟隨特性和靜態跟蹤精度。

                                                        伺服系統包括驅動裝置和執行機構兩大部分。驅動裝置由主軸驅動單元、進給驅動單元和主軸伺服電動機、進給伺服電動機組成。步進電動機、直流伺服電動機和交流伺服電動機是常用的驅動裝置。
