Title:
CHUCK DEVICE
Document Type and Number:
Japanese Patent JP2017074626
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a chuck device not weakening chuck force even when being rotated at high speed, for example, at about 6,000 rpm, and capable of showing stable chuck force.SOLUTION: When a rotor is rotated by drive of a rotary drive mechanism, the other side in the longer direction furthermore than a pivot shaft of a clamp claw member is fluctuated to the reverse chuck surface side. Hereby, when the other side in the longer direction is fluctuated to the reverse chuck surface side of a workpiece, one side in the longer direction furthermore than the pivot shaft is fluctuated to the chuck surface side of the workpiece, and thereby a clamp part on one side in the longer direction is press-contacted onto the chuck surface of the workpiece.SELECTED DRAWING: Figure 1
