ABSTRACT:
A tool changer has a rotatably supported driving shaft, a cylindrical double-walled support member composed of an inner cylindrical wall and an outer cylindrical wall, disposed coaxially with the driving shaft, and engaged therewith through helical splines, a cylindrical guide member having a cylindrical portion interposed between the inner cylindrical wall and outer cylindrical wall, a plurality of claw members fixed to the outer cylindrical wall for retaining tools, and a servomotor for rotating the driving shaft clockwise and counterclockwise. In an outer periphery of the cylindrical portion of the guide member are formed a plurality of axially extending straight grooves, each having an inclined side surface at respective tip ends, which extends in one direction, and an engaging member biassed by a spring member projects into one of the straight grooves so as to be engaged therewith. The clockwise rotation of the driving shaft causes the support member to move forwardly in an axial direction while the engaging member is engaged with one of the straight grooves of the guide member. At an end of the forward movement of the support member, the engaging member leaves the straight groove after passing the inclined side surface so as to rotate the support member by a predetermined angular distance and to bring the engaging member into engagement with another one of the straight grooves. The succeeding counterclockwise rotation of the driving shaft causes the support member to move backwardly.
