Japanese Patent JPS5040272
Kind Code:
B1
Abstract:
A quill spindle having a chuck, a pair of springs producing a resultant force on a pair of internal sleeves for urging the chuck into a chucking position, and an internally slideable coupling device, operable by an external device, for sliding one of the sleeves against the force of one of the springs to permit the other spring to automatically slide the other sleeve away from the chuck to remove the chucking force. A cap nut is connected to the forward end of the spindle to provide a stop for the chuck, and a flange is provided on the front of the spindle for circumferentially encompassing the cap nut to maintain the cap nut in accurate alignment. The coupling device includes a sleeve disposed within the quill for sliding movement in response to a force generated by the external device, for actuating a ball and eccentric socket mechanism coupled to one of the internal sleeves.
