Abstract
PURPOSE: To obtain a chuck unit capable of tightening the rod with a fixed force at all times even though the energizing force of spring becomes less due to a gap between the chuck and the rod.
CONSTITUTION: When the cylinder 26 is operated and the chuck piece 14 is opened to put the boring rod 20 in the chuck unit proper 10, the dished spring 24 is pressed in the direction of the arrow B and is bent. In this state, when the cylinder 26 is retreated, the ring 12, which can freely be slided on the outer circumference of the unit proper 10, is energized by the spring 24 in the direction of the arrow A, a force F2 is applied to the chuck piece 14, which is linked to the ring 12 through the cylinder 16, in the direction perpendicular to the axis of the unit proper 10. When a gap is produced between the said piece 14 and the rod 20 on account of wear, the chuck piece 14 descends, the ring 12 moves in the direction of the arrow A, and the angle of inclination θ of the cylinder 16 is made less. Thus a fixed tightening force can be obtained.
