Abstract

The present invention discloses one kind of automatic door assembly for numberically controlled machine tool. The automatic door assembly includes one door sheet unit, one driving unit and one interlock unit. The driving unit has one motor, one shaft coupling and one driving wheel; and the interlock unit has one driven wheel, one flexible element set between the driving wheel and the driven wheel and one interlock part fixed to the door sheet unit and interlinking with the belt unit. The driving unit drives the door sheet unit through the flexible element, and the resistance to the door sheet unit may be returned through the belt unit for the shaft coupling to be separated from the motor and the motor to rotate idly, so as to reach use safety.
