摘要

The tool holder is particularly for a heavy-duty lathe with automatic tool-changing mechanisms, being clamped in the vertical and horizontal directions on a mounting piece. The holder (3) has a vertical (14) and a horizontal keyway, and an inclined T-section groove with recesses (9) and ribs (21). The mounting piece (4) has a straight T-section groove and vertical and horizontal mating faces with keys. The wedge-shaped key (7) in the two T-section grooves is of T-section with a ramp face on one side. On this side it has recesses (8) and ribs (24) engaging in the toolholder.
