Abstract
A work piece support device features two pincer members which can be moved toward and away from each other and which can be varied in length in manner to accommodate different shaped work pieces. The device is mounted on a manipulator which selectively displace the same in three mutually opposed directions. Location and locking probes can be used in combination with the support device to locate and/or lock the work piece in place.
Claims4
In a device for supporting a work piece , first and second pincer members, said first and second pincer members being disposed on a base member in a manner to be slidably movable toward and away from each other, said first pincer being elongatable;
- first and second work receiving members, said first and second work receiving members being disposed at the upper ends of said first and second pincer members;
- first drive means associated with said first and second pincers for moving said first and second pincers toward and away from [one another] each other , said first drive means including a device which converts rotational motion into linear motion;
- second drive means associated with said first pincer for selectively elongating [the same] said first pincer ;
- and
- a location [device] means comprising a probe mounted adjacent said first and second pincers and operatively connected [with] to a servo [device to enable the probe to be extended] extension means for extending said probe to engage [a location] with an aperture formed in [the] a work piece supported on said device.

- first drive means associated with said first and second pincers for moving said first and second pincers toward and away from [one another] each other , said first drive means including a device which converts rotational motion into linear motion;
- [and]
- second drive means associated with said first pincer for selectively elongating [the same] said first pincer ;
- and
- a work piece retention device comprising a probe member having a projection formed thereon, said probe member being mounted adjacent said first and second pincers, [and being operatively connected with a servo device to enable it to be selectively extended so as to pass through an aperture in the work piece being supported on said device and then rotated such that when said probe is retracted toward said servo device, the projection engages said work piece and secures the same in] means for supporting said probe member in an extendable and rotatable manner, means for rotating said probe member to a first angular position and for extending it in said first angular position through an aperture formed in said work piece, and means for rotating said probe member to a second angular position and for retracting it in said second angular position, so as to engage said projection against the work piece to secure the work piece in a predetermined position on said device.
