"Longitudinal section view" has been corrected as follows. ``Figure 1 is a vertical cross-sectional view of the chuck device in a state where it grips a workpiece, and Figure 1a is a vertical cross-sectional view of the same chuck device in a state where the workpiece gripping force is released.''

Claims

[Scope of utility model registration request]

In a chuck device for a machine tool that removably holds a workpiece at the tip of a rotationally driven spindle, the chuck unit is integrally attached to the tip of the spindle, and the axial center of the chuck unit is expanded radially by the force of a spring to hold the workpiece at the tip of the spindle. In addition to providing a collection chuck that engages with the reference hole of the workpiece, three chuck pawls are arranged at equal intervals in the circumferential direction on the periphery of the chuck unit, and the chuck pawls are each engaged with each other via a tapered surface. three chuck rods capable of moving the chuck pawl in the radial direction by moving the chuck pawl in the axial direction, and the chuck pawl is attached to the chuck unit so as to be swingable in a plane perpendicular to the axis. , a machine tool chuck device characterized by being supported.
