A hand tool includes a replaceable cutting portion having an elongate cutting surface, a body and a handle. The body receives displaceable protecting apparatus for shielding the cutting surface of the cutting portion when not in use. A forward distal end of the protecting apparatus contacts a portion of the surface of the object to be cut such that when pressure is applied against the object surface displacement of the protecting apparatus relative to the replaceable cutting portion is effected to expose only as much of the cutting surface as needed to effect the required cut. Alignment means maintain alignment of the replaceable cutting portion relative to the protecting apparatus throughout the cutting. When the cutting action is completed resilience means facilitates return of the protecting apparatus so the cutting surface is no longer exposed.

It is determined whether the first tool identification information that is output from a robot control device, and that indicates a present tool and the second tool identification information for detecting and identifying a tool attached to the robot are unequal to each other. The position coordinates of the taught reference point in an actual space of the robot occurring at the time when the unequalness therebetween is first detected are set as reference coordinates, and a region that contains the reference coordinates is set as a predetermined region. If the position coordinates of the taught reference point have come to exist outside the predetermined region during a period during which it is determined that the foregoing two pieces of information are unequal, an emergency stop signal for causing the robot to be in a safe state is output.

An automatic tool changing device capable of cleaning a contact surface of a spindle, which is to be in contact with a tool holder, with a simple structure. The device includes a turret having a plurality of grippers on its outer circumference and holding the tool holder by means of the grippers. At the time of tool change, the grippers grip and pull out the tool holder fixed to the spindle. Rotation of the spindle causes the turret to rotate through a spindle gear, a turret gear, and a decelerating device, to thereby select a tool. At this moment, a coolant is spouted from a nozzle portion of a manifold toward a spindle taper hole in which the tool holder is interfitted and washes the taper hole. Due to the rotation of the spindle, the coolant is spouted onto the whole circumference of the taper hole, and the surface to be in contact with the tool holder is surely washed. Therefore, it is possible to perform the cleaning with a simple structure in which the nozzle portion is arranged near the spindle without machining the spindle and the tool holder.
