周向振动钻床钻夹头整体松脱解决方法研究

Research on the solving method for the entirety loosening of drilling chuck of peripheral vibration drilling machine

分析了周向振动钻床钻夹头整体从钻床主轴上松脱下来的原因 ,提出了极限摆振圆频率的概念 ,给出了极限摆振圆频率的计算公式 ,用事例验证了公式的正确性。找出了解决这一问题的办法 ,并提出了一些设想。实验表明 ,该方法简便、有效。

The reason of entirety loosening of drilling chuck from the drill spindle of peripheral vibration drilling machine was analyzed. A concept of limit vibratile angular frequency was put forward. The calculation formula of this limit frequency was presented, and the correctness of this formula was verified by practical example. Measures to solve this problem were found, and some assumptions was proposed. The experiment indicates that this method is simple, effective and practically feasible.
