Abstract
A side operated clamp for a resharpenable insert tool holder includes a clamping member movable into a converging recess on the tool holder body to clamp the tool insert against a shelf on the tool holder body. An actuator is movable transversely in a transverse slot extending across the tool holder. A threaded member is rotated to cause the actuator to move. The actuator has a projecting portion fitting into a dovetail keyway on the clamping member. The keyway is inclined to the transverse axis to cause clamping/unclamping movement when the actuator moves in the transverse slot.

Improved side actuated clamping device for a toolholder adapted to receive and clamp a resharpenable tool insert in a recess, the recess defined by a top shelf, spaced sidewalls, a rear wall joining said top shelf, and a bottom wall with a planar surface joining said rear wall, the recess converging toward said rear wall, the improved clamping device comprising:
- a transverse slot having a slot opening defined in the bottom wall planar surface and extending transversely across the recess,
- an actuator having a longitudinal axis, said actuator disposed in said transverse slot and adapted to traverse the slot along its longitudinal axis, said actuator having a portion protruding above the bottom wall planar surface,
- means for moving said actuator in said transverse slot, and
- a clamping member having a top wall and a bottom planar wall arranged to slide on the toolholder bottom planar wall perpendicular to a transverse line lying in said clamping member bottom planar wall so as to clamp a tool insert between its top wall and the top shelf, said clamping member defining a slot for receiving the actuator protruding portion, the clamping member slot having an axis forming a first angle with said transverse line across the clamping member.
