摘　　要：为提高楔式动力卡盘的定心精度,基于分组互换法的原理,结合实际生产中的需要,建立了卡盘盘体和楔心套的分组互换装配法,并对基于该方法生产的动力卡盘高爪配车后的定心精度进行了实验研究。实验结果表明,对于型号为KT55200的卡盘,使用分组互换法将盘体和楔心套装配间隙控制在10μm以内,可以有效提高卡盘的重复定心精度。该方法对高精度动力卡盘的设计制造有重要的实践意义。In order to improve the centering accuracy of wedge- hook power chuck,the grouping exchange method for assembling the chuck body and wedge plunger was developed,on the basis of the principle of grouping exchange method and actual production requirement. Using this method,series of power chucks were produced. Experiments on the centering accuracy after turning top jaws were conducted. The experimental results show that,when the interval between chuck body and wedge plunger is limited within10 μm,the grouping exchange method is effective to improve the centering method of chuck KT55200.This method has important practical significance in the design and manufacture of power chuck.
