近些年来,液压扩胀式夹具在机械加工及其测量等方面的应用日趋增加,这是因为这种夹具,具有如下特点: 1.用液性介质传递夹紧力均匀适度,有利于实现自动定心夹紧或多件、多次夹紧。 2.夹具的定位夹紧弹性元件(薄壁套)扩胀变形均匀,能使夹紧力均匀分布于工件整个 In recent years, hydraulic expansion of the fixture in the machining and measurement applications, such as increasing, it is because of this fixture, has the following characteristics: 1. Using liquid medium transmission clamping force is moderate and moderate, to achieve automatic Centering clamping or more pieces, multiple clamping. 2. Fixture positioning clamping elastic element (thin-walled sleeve) expansion deformation uniform, enabling the clamping force evenly distributed throughout the workpiece
