Abstract

The self gripping chuck is mounted on the shaft running in a bearing in the machine tool body. the chuck is in two halves, the first is mounted directly on the shaft, the second half can slide along the machine axis relative to the fixed half. A washer spring assembly acts to force the two halves apart. Three jaws for gripping the workpiece have a wedge shaped base seated on a correspondingly shaped section on the fixed half of the chuck. To insert the workpiece the end of the chuck is pressed inwards against the spring pressure. On release the moving half of the chuck is moved outwards forcing the jaws through the wedges radially inwards on to the workpiece.
