Abstract
A quick-change system for changing a collet or bit on a tool has a base member to be attached to the body of the tool, an input member to be selectively latched to or unlatched from the tool body, an output member coupled to the input member via a torque multiplication device and having splines that are engageable and disengageable with a collet nut for the tool having a splined member when the two parts are moved relative to each other a given axial distance. When the input member is latched to the tool's body, the output member and the collet nut are disengaged so as to allow the collet nut to rotate with the tool's spindle during operation of the tool. When the input member is unlatched from the tool's body, it can rotate freely and is spring biased to cause the collet nut and output member to move into engagement such that torquing the input member loosens or tightens the collet nut to release or clamp the bit, respectively. The torque multiplication device can be a planetary gear system or other torque transmission system.
