摘要
主要介绍了数控钻铣床手动进给机构的工作原理,分析了机构中平面蜗卷弹簧的弹簧预紧圈数和弹性系数选择与进给手柄上力矩及步进电机所需驱动力矩的关系。
The work principle of a hand feeding mechanism of numerical control drilling and milling machine is pre-sent ed and the number of pre-tight rolls and the selection of the elastic parameter of the whirl spring are analyzed.The re lationship between the torque on the handle and the stepping motor is introduced.
