DEVICE FOR LOCKING TURRET OF CNC MACHINE

摘要

PURPOSE: A fixing device of a turret rotating body for a CNC(Computer Numerical Control) multiple-shaft machine is provided to enable the state of a turret assembly to be rapidly sent to a worker since the electrical signals of a piezoelectric element generated by vibration in operation of a spindle are calculated and thus the state of a turret assembly is sensed. CONSTITUTION: A fixing device of a turret rotating body(11) for a CNC(Computer Numerical Control) multiple-shaft machine comprises a turret assembly(1), a position sensor(2) and an actuator(3). The position sensor is installed on one side of the housing of the turret assembly. The position sensor senses the right position of the spindle mounting unit(11a) of the turret rotating body. The actuator is installed on the other side of the housing. The actuator interlocks with the output signals of the position sensor. A plurality of grooves are formed on the circumferential surface of the turret rotating body at regular intervals.
