Cutter insert fixture for tool shank - has drilling at acute angle to base to accommodate convex component engaged by notched screw

摘要

The equipment secures a cutter blade in a recess near the periphery of a tool shank, the blade bearing against the base and side of the recess. A drilling runs at an acute angle from the base and intersects the plane in which one of the sides lies accommodating a component with a convex face bearing against its wall and a pin at the end protruding near the base to engage in a drilling (19) in the cutter plate (14). The other end of this component (16) engages in a notch (20) in a screw (22) in a tapped hole in the tool shank and allow the component to slide in its drilling (15). Its end engaging with the screw can be hooked, the screw having an undercut annular groove to accommodate the hook.
