摘　　要：高强度螺栓的疲劳寿命决定了飞机飞行的安全系数,滚压强化是提高螺栓疲劳寿命的重要方法。传统的滚压方式一般是采用手动操作机床滚压,存在加工一致性差、精度低、表面粗糙度不好等问题。为了解决此类问题,提出采用高精度接触式测头通过编程的方式实现滚压轮微米级对刀以及螺纹牙底的动态测量。结果表明,通过程序控制滚压轮的重复对刀精度可保证在0.01 mm以内;螺纹滚压动态测量程序能够有效地控制滚压路径及滚压量,保证滚压误差不超过0.01 mm,当滚压深度为0.05 mm时,螺纹滚压后表面粗糙度较滚压前减小了55.8%。The fatigue life of high-strength bolts determined the safety factor of aircraft flight,and rolling strengthening was an important method to improve the fatigue life of bolts.The traditional rolling method generally adopted manual machine tool rolling,which had problems such as poor processing consistency,low precision and poor surface roughness.In order to solve such problems,a high-precision contact probe was proposed to realize the micrometer level tool setting of rolling wheel and dynamic measurement of thread bases through programming.The results showed that the repeated tool setting accuracy of the roller could be guaranteed to be within 0.01 mm by program control;and the dynamic measurement program of thread rolling could effectively control the rolling path and rolling amount to ensure that the rolling error did not exceed 0.01 mm.When the rolling depth was 0.05 mm,the roughness of thread after rolling was reduced by 55.8% compared with that before rolling.
