PURPOSE: An automatic tool exchanger of a machining center is provided to minimize the reciprocating lifting length of a cylinder by an operating member to rotate a tool port, to minimize the volume of a facility, and to reduce the length of a shaft connecting the cylinder and a roller housing. CONSTITUTION: An automatic tool exchanger of a machining center comprises a rotary type magazine(100), a first electric motor(150), a cylindrical tool port operating member(200), a cylindrical tool port operating member cover(250), a changer arm(300), and a second electric motor(350). The cylindrical tool port operating member includes a roller housing(210), a lifting shaft(220), and a pneumatic cylinder(230). |
