摘　　要：功率超声振动珩磨就是通过在油石上施加功率超声振动,以进行珩磨。与普通珩磨相比,这种加工方法在加工时产生的珩磨力较小、珩磨温度低、在提高表面质量的同时油石磨损较小、最重要是加工精度高。针对发动机缸套的超声振动珩磨设计了一套专用的定位加工的夹具。该夹具采用外抱式结构,在夹具体和缸套之间填充液性塑料这种介质,由此介质均匀的将力施加到弹性套上,从而实现了缸套的轴向夹紧。夹具克服了在传统缸套加工中难实现定心定位,易轴向变形的缺点。Power ultrasonic vibration honing is applied in abrasive stick on the ultrasonic vibration honing.It designs a set of special fixture for positioning processing of engine cylinder liner of ultrasonic vibration honing.Compared with ordinary honing,when being processed,this kind of method is with lesser honing force,and with low temperature,and when improving surface quality,the stone wear is smaller.The most important thing is its high machining accuracy.It designs a set of special fixture for positioning processing of engine cylinder liner of ultrasonic vibration honing.This fixture uses external contracting type structure,filling liquid between fixture and cylinder liner,and from this medium the force is applied to the elastic sleeve,so as to realize the axial clamping of the cylinder liner.The clamping overcomes traditional shortcomings of hard centring positioning and axial deformation.
