A tool holder, in particular a turning tool holder, is equipped with a rapid locking system (4 to 10 inclusive) for the mechanical fastening of interchangeable inserts (21) to the tool holder body (1). The inserts may be made of Tungsten Carbide, Cermet, Ceramics, PCBN (Diamond Cubic Boron Nitride) or PCD (Polycrystalline Diamond). The rapid locking system (4 to 10) consists of a clamp (5), a drive pin (7) and a cylindrical pin (8) mounted on the drive pin (7). The cylindrical pin (8) extends radially with respect to the drive pin (7) and cooperates with two cams (10), each of which is equipped with a helical section (S) developed on an arc of 90 degrees. The cams (10) and the cylindrical pin (8) of the rapid locking system (4 to 10) are located inside a housing seat (23) formed in the tool holder body (1). The rapid locking system (4 to 10) allows an interchangeable insert (21) to be locked to the tool holder body (1) through a rapid action that allows a reduction of the time needed to index or to replace the insert (23). |
