Abstract

A gripper has a body with a jaw support portion and powering portion. A powering assembly is positioned in the powering portion. A stationary jaw is secured to the jaw support portion. A movable jaw is pivotally secured to the jaw support portion about a pivot pin. A rod from the powering assembly connects in a slot on the movable jaw. The pivot pin is positioned on an opposite side of an axis of the rod on the clevis portion away from the stationary jaw. The non-clamping end of the movable jaw is incapable of extending below an end plane of the body of the stationary jaw side of the gripper.

First claim

What is claimed is:

1. A gripper comprising:
a body having a support portion and powering portion;
a powering assembly in the body powering portion;
a stationary jaw on the support portion, the stationary jaw has a pair of legs for coupling the stationary jaw to the support portion;
a movable jaw pivotally secured to the support portion about a pivot pin, a rod of the powering assembly connected via a journal pin in a slot on the movable jaw, the pivot pin positioned on the support portion away from the stationary jaw, the pivot pin on an opposite side of an axis of the rod with respect to the stationary jaw, the journal pin extending from the movable jaw, the journal pin directly engaging a guide in the support portion such that the journal pin, in contact with the guide, moves directly on the guide without bearings, bushings or mechanical supports, and a non-clamping end of the movable jaw moves in-between the legs of the stationary jaw and is incapable of extending below an end plane of the body on the stationary jaw side of the gripper.

2. The gripper of claim 1 , further comprising a retaining member on an outer circumference of the powering portion for retaining tooling mounts.

3. The gripper of claim 1 , wherein the stationary jaw includes a sensor for sensing presence of a part.

4. The gripper of claim 1 , wherein the stationary jaw includes a knife edge for die entry.

5. The gripper of claim 1 , wherein the movable jaw slot has an overall flattened V-shape.

6. The gripper of claim 1 , wherein an axial bore is formed in a cylinder wall, defining the powering portion, for enabling fluid flow for piston activation.

7. The gripper of claim 6 , wherein a plug seals the axial bore at an exterior end of the powering portion.

8. The gripper according to claim 1 , further comprising a bi-directional mounting sensor bracket, wherein the bi-directional mounting sensor bracket is movable from one side of the support portion to the other.

9. The gripper according to claim 1 , further comprising a symmetrical sheet stop being reversible for increasing wear life of the symmetrical sheet stop.

10. The gripper according to claim 1 , further comprising a shelf on the support portion for positioning the stationary jaw.

11. The gripper according to claim 1 , further comprising a pilot bore in the support portion aligned with the pivot pin for enabling easy removal of the pivot pin.

12. The gripper according to claim 1 , further comprising a slot in the gripper body for receiving a wire, the slot being covered by a mount.

13. A robot and gripper comprising:
a robot having an end to receive a gripper;
a gripper having a mechanism connecting with the robot end, the gripper further comprising:
a body having a jaw support portion and powering portion;
a powering assembly in the body powering portion;
a stationary jaw with a pair of legs for coupling the stationary jaw with the jaw support portion;
a movable jaw pivotally secured to the jaw support portion about a pivot pin, a rod of the powering assembly connected via a journal pin in a slot on the movable jaw, the pivot pin positioned on the jaw support portion away from the stationary jaw, the pivot pin on an opposite side of an axis of the rod with respect to the stationary jaw, the journal pin extending from the movable jaw, the journal pin directly engaging a guide in the support portion such that the journal pin, in contact with the guide, moves directly on the guide without bearings, bushings or mechanical supports, and a non-clamping end of the movable jaw moves in-between the legs of the stationary jaw and is incapable of extending below an end plane of the body on the stationary jaw side of the gripper.

14. A gripper comprising:
a body having a support portion and powering portion;
a powering assembly in the body powering portion;
a stationary jaw on the support portion;
a movable jaw pivotally secured to the support portion about a pivot pin, a rod of the powering assembly connected via a journal pin in a slot on the movable jaw, the pivot pin positioned on the support portion away from the stationary jaw, the pivot pin on an opposite side of an axis of the rod with respect to the stationary jaw, the journal pin extending from the movable jaw and engaging a guide in the support portion such that the journal pin moves directly on the guide without bearings, bushing or mechanical supports, and a non-clamping end of the movable jaw is incapable of extending below an end plane of the body on the stationary jaw side of the gripper;
a retaining member on an outer circumference of the powering portion for retaining tooling mounts; and
a tool mount including a mounting key for mating with the outer circumference to retain the tool mount on the powering portion.
