Abstract

A manipulator for material removing tools and their adapters, particularly in machine tools and matching centers, has a horizontal rail for a reciprocable carrier which supports an elongated vertical holder which is movable up and down and the lower end of which carries one end of a horizontal link. The link is turnable relative to the holder about a vertical axis and its other end supports an arm which is turnable about a vertical axis and supports two tongs. The tongs are angularly offset relative to each other by 180° about the horizontal axis and at least one jaw of each tongs is movable relative to the other arm in the direction of the horizontal axis. The movements of the carrier, holder, link, arm and movable jaws are regulated by numerical controls.

Claims

1. A manipulator for tools and adapters, particularly for material removing tools and adapters for material removing tools in machine tools and machining centers, comprising a support defining a first path;

a carrier mounted on said support for movement along said first path and defining a second path extending at right angles to said first path;

an elongated holder mounted on and movable relative to said carrier along said second path;

a link having a first end mounted on and turntable relative to one end of said holder about a first axis which is parallel to said second path, said link further having a second end;

an arm mounted on and arranged to turn relative to the second end of said link about a second axis which is normal to said first axis; and

adjustable gripper means on said arm.

2. The manipulator of claim 1, wherein one of said paths is substantially horizontal and the other of said paths is substantially vertical.

3. The manipulator of claim 2, wherein one of said axes is substantially horizontal and the other of said axes is substantially vertical.

4. The manipulator of claim 3, wherein said first path is substantially horizontal and said first axis is substantially vertical.

5. The manipulator of claim 1, wherein said gripper means includes a plurality of adjustable tongs which are angularly offset relative to each other about said second axis.

6. The manipulator of claim 5, wherein said tongs include first and second tongs which are angularly offset by substantially 180°

.

7. The manipulator of claim 5, wherein at least one of said tongs comprises a first jaw and a second jaw, at least one of said jaws being movable along said arm relative to the other of said jaws in the direction of said second axis.

8. The manipulator of claim 1, wherein said holder has an upper end and a lower end and said one end is the lower end of said holder.

9. The manipulator of claim 1, further comprising means for moving said carrier and said holder along the respective paths and means for turning said link and said arm about the respective axes.

10. The manipulator of claim 9, further comprising numerical controls for said moving means and said turning means.

11. The manipulator of claim 9, further comprising means for moving said at least one jaw relative to said other jaw and numerical controls for said moving means and said turning means.

12. The manipulator of claim 9, wherein one of said moving means comprises a rack and pinion drive and the other of said moving means comprises a feed screw.
