Abstract
PURPOSE: To hold a workpiece that right angle degree of an end surface attaching to the central axis is low without generating inclination to the workpiece and without performing centering work by hand work, in this chuck provided with a plurality of grasping pawls that simultaneously open and close.
CONSTITUTION: When working, three grasping pawls 21 integrally fastened to a main slide block 36 through a lever 40 move to the outside in the radial direction by the rise of a portion material 42 for main slide when a workpiece 15 is first carried in so that the end surface 15A be pushed against the stage portions 21A of the three grasping pawls 21 and a drive rod 45 is lifted by means of a cylinder, etc. An auxiliary pawl 22 sticked to an auxiliary slide block 50 through a link 63 and a lever 55 is shifted to the outside in the radial direction by the rise of portion material 57 for auxiliary slide. When the drive rod 45 also rises continuously after the auxiliary pawl 22 contacts with an inner surface of the workpiece 15, a spring 58 is compressed, and the auxiliary pawl 22 is strongly pressure-contacted.
