,具体涉及一种新型超声加工压帽结构。
技术介绍
当前一些特殊材料应用越来越广泛,比如玻璃、蓝宝石、碳化硅、复合材料等。这些材料由于机械特性很硬脆,导致采用传统的加工工艺无法满足这些材料的加工精度的要求。当前行业采用了超声能量辅助的方式,结合现有机床的高速旋转,用于这类硬脆材料的可加工性、加工精度、以及提高加工刀具的寿命。在超声辅助加工中,超声能是加工工艺最为关键的参数,其起到激发材料原子能,降低切削力等作用。换能器(Transducer)是超声加工中提供超声能量的核心执行机构,其工作原理为利用压电逆效应将频率电信号转换为高频超声振动,并将超声能传输到加工材料。当前超声刀柄结构中,通过压帽的旋转与弹性夹头相配合,实现将加工刀具(或称磨头)锁紧在刀柄的变幅杆末端。虽然传统的压帽能实现配合固定的目的,但是其的结构体积大、重量高,并且内螺纹联接长度有限,限制了超声能量的传输,导致超声能量在传统压帽处损失过大,最终加工刀具获得的超声能量大幅度下降,甚至影响了加工效率、刀具寿命与加工品质。
