摘要
提出用摆动导杆机构近似替代低频振动攻丝机中的简谐扭振机构,对近似替代的可能性和可行性进行了分析。得出结论:当曲柄长度与机架长度之比小于０．１时,摆动导杆机构可以足够精确地输出正弦函数。给出了该机构在攻螺纹直径为 Ｍ６的低频振动攻丝工作台中的应用实例。
It is put forward to replace the simple harmonic torsional vibration mechanism with the oscillating guard bar mechanism in low frequency vibration tapping machine. The possibility and feasibility of replacement is analyzed. It can be concluded that oscillating guard bar mechanism can output sine function accurately when the ratio of the crank length to the brace length is less than 0.1. A real example of working table of low frequency vibration tapping machine with the thread diameter to tap of 6mm is also given.
