Automatic tool change unit

摘要

The first (29) and second (30) transmissions each have a translatory movable slide (33,34). They are retained in the housing (15) to move in a direction approximately parallel to each other. A crank (37) is common to both slides. It is driven by a motor and carries a single cam (38) which is allocated to both slides and which with rotation of the crank is brought into contact with a respective cam track (51,52,49) on the slide to effect the movement of the slide.
