PURPOSE:To check a vibratory rock occurring by installing a second contour part which supports a tool magazine turning from a tool changing position to the retracting position on a cam surface of a tool change starting cam via a driven lever. CONSTITUTION:When a driven end 28 of a driven lever 26 as a second cam contour surface 24 comes off a first cam contour surface 22 in incline form, there is provided with a flat cam surface to be engaged in the next. Consequently, in conformity with support of the first cam contour surface 22 formed into the flat cam surface, the driven end 28 of the drive cam 26 is engaged with the second cam contour surface 24 even after a tool magazine 42 is completely reset to its retracting position, and this tool magazine 42 also continues to receive a supporting action by the driven lever 26. Accordingly, turning operation of the tool magazine 42 from a tool changing position to a tool retracting position is performed under mechanical support of the driven lever 26, so that a vibratory rock produced in a tool changer is thus checkable. |
