摘　　要：静压膨胀夹具是一种超高精度夹具,夹持回转精度可以达到≤3μm;尤其适合于夹持薄壁工件和难夹持工件,解决高精度加工中的夹持难题。文章介绍了静压膨胀夹具的工作原理、典型的应用实例和应用特点。The hydraulic expansion fixture is a kind of ultra - precision fixture. The true running accuracy of the expansion fixture is less than 3μm. The hydraulic expansion fixtures are used to solve workholding puzzle, especially for thin - walled parts and the workpieces which are hard to hold. The principle and characteristics of hydraulic expansion fixture, as well as some typical application examples have been introduced in this paper.
