Gripper provided with an adjustable sensor assembly
A fluid actuated parts gripper assembly is provided. The fluid actuated parts gripper assembly has a pair of opposable pivoting jaw members, a fluid driven actuator, a linkage structure, a sensor target, a mounting and a sensor. The linkage structure is driven by the fluid driven actuator and is coupled to at least one of the pair of opposable jaw members. The sensor target is coupled to the linkage structure and is movable therewith. The mounting is located adjacent the sensor target and the sensor is mounted on the mounting configured to detect the sensor target.
1. A fluid actuated parts gripper assembly comprising:
first and second opposable jaw members;
a fluid driven actuator configured to move at least one of the first and second opposable jaw members;
a sensor target movable with at least one of the first and second opposable jaw members;
a mounting located adjacent the sensor target; and
a sensor mounted on the mounting configured to detect the sensor target;
wherein the mounting is adjustable relative to the sensor target.
2. The gripper assembly of claim 1 , wherein the mounting is adjustable relative to the sensor target.
3. The gripper assembly of claim 1 , wherein the sensor is fixed relative to the mounting.
4. The gripper assembly of claim 1 , wherein the mounting is configured to receive the sensor target, and wherein the sensor target is moveable within the mounting.
5. The gripper assembly of claim 4 , wherein the mounting includes a slot within which the sensor target is moveable.
6. The gripper assembly of claim 1 , wherein the mounting comprising at least one slot configured to receive a fastener that selectively fixes the mounting to the gripper.
7. The gripper assembly of claim 6 , wherein the at least one slot is a pair of slots.
8. The gripper assembly of claim 1 , wherein ad adjustment member is coupled to the mounting for incrementally adjusting the location of the mounting relative to at least one of the pair of jaw members.
9. The gripper assembly of claim 8 , wherein the adjustment number is an adjustable spacer comprising a body having a plurality of sides, each of the plurality of sides located at a different length from a central location on the body.
10. The gripper assembly of claim 9 , wherein the central location of the adjustable spacer is a bore disposed there through.
11. The gripper assembly of claim 9 , wherein the adjustable spacer has opposed surfaces, each being non-equidistant from the location.
12. The gripper assembly of claim 11 , wherein the adjustable spacer is a hexagonal body with opposed surfaces each being non-equidistant from the location.
13. The gripper assembly of claim 12 , wherein the at least one of the opposed surfaces of the adjustable spacer is positionable adjacent an abutment located on the mounting to selectively reposition the mounting relative to the gripper assembly.
14. The gripper assembly of claim 8 , wherein the member is a pivot body that pivots about an axis of rotation and is engagable with a portion of the mounting a distance spaced apart from the axis of rotation.
15. The gripper assembly of claim 14 , wherein an engagement member attached to the pivot body is engagable to a corresponding receiver in the mounting to secure the mounting to the gripper assembly a determined position.
16. The gripper assembly of claim 15 , wherein the engagement member is engagable with a plurality of receivers in the mountings.
