过去,在车削电机轴承套内孔时,大多使用普通三爪卡盘,不仅装卸频繁,精度低,劳动强度大,工作效率低。而且三爪卡盘损耗快。离心式自动松紧夹具不需要外加动力。车削时,只要把工件放进夹具,车床一开动,便能牢固地夹紧工件,加工完毕后,车床一停,夹紧力便自动消失而取出工件。这样 In the past, when turning the bore of the motor bearing sleeve, the common three-jaw chuck was mostly used, which not only has frequent loading and unloading, low precision, labor intensity and low work efficiency. And three-jaw chuck loss quickly. Centrifugal automatic elastic clamp does not require additional power. Turning, as long as the workpiece into the fixture, a lathe start, you can firmly grip the workpiece, the processing is completed, the lathe stop, the clamping force will automatically disappear and remove the workpiece. such
