초록 ▼

A rotary device has a releasable tool holder. A spindle with two ends has one end adapted to secure to a rotary device and the other includes a bore to receive a tool. A mechanism to retain and release the tool from the spindle bore is coupled with the spindle adjacent the bore end. At least two unlike retention members to apply a force on the tool in the bore are adjacent the bore. A sleeve surrounds the bore end of the spindle as well as the at least two unlike retention members. The sleeve has a common surface to apply a force on the at least two unlike retention members such that when the sleeve is axially moved along the spindle, the force is varied with respect to the position of the surface on the retention member. This force maintains the tool in the bore or enables the tool to be removed from the bore. A biasing member maintains the sleeve in a retention position on the spindle.

[ What is claimed is:] [1.]1. A releasable tool holder, comprising:a spindle having two ends, one end adapted to secure said spindle with a rotary device and the other end including a bore to receive a tool;a mechanism for retaining and releasing a tool from said spindle bore, said mechanism coupled with said spindle adjacent said bore end, said mechanism comprising three balls for applying force on a tool in said bore for retaining the tool in said bore;a sleeve surrounding a portion of said spindle and said three balls, said sleeve including a common tapered surface in contact with each of said three balls, said tapered surface applying a force on said three balls such that as said sleeve is axially moved on said spindle, said force varies with respect to the position of said tapered surface on said balls which, in turn, maintains the tool in the bore or enables the tool to be removed from the bore, and a pair of springs, one for maintaining said sleeve in a retention position on said spindle and the other for registering the balls on the spindle.
