发明名称 APPARATUS FOR AUTOMATICALLY RETURNING REFERENCE POINT OF MACHINE TOOL AND METHOD THEREOF
摘要 A device for automatically returning a home position of a machine tool and a method thereof are provided to detect a dog for sensing the home position to return the home position if an operator orders the return to the home position. A device for automatically returning a home position of a machine tool comprises: an Z-axis transfer servo motor(10) operating a screw(80) to the clockwise direction or the counter-clockwise direction; an Z-axis head(20) going up and down relative to the rotation of the Z-axis transfer servo motor; a dog(30) for sensing the home position to limit home position of the Z-axis head; a top limit dog(40) sensing the Z-axis head positioned in the top when being contacted with the Z-axis head; a bottom limit dog(50) sensing the Z-axis head positioned in the bottom when being contacted with the Z-axis head; and a home position approaching switch(60) for sensing the home position to detect the present location of the Z-axis head by sensing the top and bottom limit dog.
