Quick-Change Tool Holder with Center-Height Adjustment Mechanism

摘要

A quick-change tool holder includes a center-height adjustment mechanism for adjusting the center height of the cutting tool. The quick-change tool holder includes a tool support member which is adapted to be mounted on a lathe turret or mounting block of a machine, a cutting head formed with a seat for receiving a cutting tool, and a clamping mechanism for clamping the cutting head to the support member. The tool support member includes an axial bore which receives a tubular shank of the cutting unit. The clamping mechanism is disposed within the axial bore and includes a pair of radially expandable locking elements to engage the tubular shank of the cutting unit. The clamping mechanism includes a key which engages with a corresponding keyway on the tubular shank for angularly locating the cutting unit. An adjustment mechanism is provided for rotating the clamping means about a longitudinal axis of the support member to change the angular location of the cutting unit. The center height of the cutting tool is determined by the angular location of the cutting unit.
