ABSTRACT:
A tool, such as a drill bit, cutting tool or any other suitable tool, is d in a two component tool holder. The first component (1) includes a holder sleeve (3) with a conical bore (2). The sleeve (3) is held in a housing (19) carried by a machine tool, robot or the like. The second component (25) which carries the tool proper has a conical shaft (26) with a locking groove (29) near its free end. The conical shaft (26) locks into the conical bore (2) in the sleeve (3). An additional automatic locking is provided by at least two locking bolts (12) located to reach radially through the sleeve (3) into the locking groove (29) when the shaft (26) is inserted into the conical bore (2) of the sleeve (3). The locking bolts (12) are biased by springs (14) into the locking position and pulled out of the locking position by pneumatic or hydraulic pressure operated elements. Centering pins (4) and centering grooves (38) cooperate with each other to make sure that the conical shaft (26) is properly and automatically received in the conical bore (2). Both components carry pressure supply connector elements and electrical connector elements of the plug-in type.
