<p>According to the present invention, a tilting head driving device for a machine tool, wherein a tilting head (6) has a tilting body unit (8) and a spindle head unit (7) mounted to be tilted in the tilting body unit (8), comprises: a drive unit (10) installed inside the tilting body unit (8) and generating rotational power for tilting of the spindle head unit (7); an input terminal (30) for transmitting the rotational power generated in the drive unit (10) to the spindle head unit (7); and an output terminal (40) for tilting the spindle head unit (7) with the rotational power transmitted from the input terminal (30). Drive accuracy and power transmission efficiency can be improved by a gear arrangement structure which is formed more than or equal to two stages and three rows. Processing accuracy of a workpiece can be increased by minimizing backlash to occur.</p> |
