1、数控铲磨床纵向进给系统的设计摘要铲磨床是滚刀、成型铣刀等复杂刀具的精加工机床。由于传统铲磨床加工精度下降、生产效率低,工人劳动强度大,本设计对传统铲磨床的纵向进给机构进行数控化改造来改善其上述不足之处。通过对目前工厂中传统的铲磨床进行研究,参考数控机床的相关文献,了解铲磨床纵向进给部分的工作原理,并深入分析铲磨床在加工的过程屮各个零部件的受力情况,按寿命计算选择了丝杠的尺寸规格,并校核了额定动载荷、传动效率、刚度,最终选择了汉江机床厂生产的滚珠丝杠。通过对主轴受力的分析选择了用推力球轴承承受轴向力,用深沟
2、球轴承承受径向力的形式。异轨的选取参考了汉江机床厂生产的滚动导轨,对导轨的寿命以及额定载荷进行了校核,均能满足耍求。电机根据滚珠丝杠的导程计算出的最高转速,和传动过程屮的最大转矩选取了富士公司的伺服电机并对转动惯量进行了校核。由于采用了闭环系统,在查阅了光栅尺的相关参数后,选择FAGOR公司的光栅尺能使在规定的行程内定位分辨率达到耍求。通过上述设计实现了铲磨床纵向进给系统的数控化改造,满足了加工精度的要求,具有加工稳定可靠,效率高等优点。关键词:数控铲磨床;纵向进给系统;精加工;闭环系统A4-挡块,Aut
