Tool changing safety device of a CNC turning center

摘要

The subject innovation can include first, second and third coupling such, if after turning milling tool coupling for fixing the spindle of the switching ring portion not operate to sense this, the inner housing (2) of the tool switch the safety device of the machine tool and the first rod 30 is formed in association with the (11, 12, 13) to move a constant distance horizontally, in accordance with the horizontal movement of the first rod 30, the end of the first rod 30 to the upper through the outer housing 3 vertically for movement is formed with a second rod (50) extending a predetermined length, the external housing 3 is provided to detect the rising height of the second rod 50, the first, also it characterized in that the proximity sensor 60 is provided to sense the presence of 2,3 coupling (11, 12, 13).
