PURPOSE: To keep a tool magazine from existing in a range of collision with a workpiece table or the other structures and to minimize the moving distance for tool change by supporting two grip pincers in such a manner as to separately move vertically and be rotatable and static in a guide device. CONSTITUTION: A tool changing device includes a double grip part 12 having two grip pincers 13 on the diameter of a swivel shaft which can be turned in a 180-degree arc within a plane crossing the shaft center of a spindle 4. The grip pincers 13 are extended substantially over the vertical distance between the tool grip part 5 of the spindle 4 and a tool magazine 10 in the direction of the swivel shaft of the double grip part 12, and supported separately in such a manner as to move vertically and be rotatable and be static in a guide device 14 connected to the turning driving part 15 of the double grip part 12. Accordingly, with tools of various lengths suspended in the tool magazine 10, even the longest tool 6 can be arranged without a collision with the workpiece and the other structures on the workpiece table 1 when the spindle 4 moves. |
