Abstract
A modular gripper assembly having body with a yoke structure defined at one end thereof and an actuator at an opposite end for reciprocally driving a piston assembly within the yoke structure. A pair of opposable jaw members having through-slots formed therein are provided within the yoke structure and coupled to the piston assembly by a cam pin so that at least one of the opposable jaw members pivots when the piston assembly moves washing the yoke structure. The jaw members are removable and interchangeable.
Claims21
A modular gripper assembly which comprises:
- a body having a yoke structure defined at one end thereof by a pair of spaced apart wall members, and a fluid driven actuator at an opposite end;
- a pair of opposable jaw members, having tip ends which are aligned with one another, at least one of the pair of opposable jaw members being pivotal within a plane and each of the pair of opposable jaw members having through-slots therein and being independently removable and replaceable by other jaw members;
- a single cam pin extending into the through-slots of each of the pair of opposable jaw members;
- and
- a linkage structure driven by the fluid driven actuator and coupled to the single cam pin between the pair of opposable jaw miembers along a direction which is substantially perpendicular to the plane.
A modular gripper assembly which comprises:
- a body having a yoke structure defined at one end thereof by a pair of spaced apart wall members and a fluid driven actuator at an opposite end;
- a pair of opposable jaw members having tip seats, at least one of the pair of opposable jaw members being pivotal, at least one of the pair of opposable jaw members including a continuous arcuate portion between opposing inner surfaces of the jaw members which continuous arcuate portion extends between the tip seat and the one end of the main body portion thereof so as to provide additional clearance between the jaw members, each of the pair of opposable jaw members having though-slots therein and being independently removable and replaceable by other jaw members;
- a single cam pin extending into the through-slots of each of the pair of opposable jaw members;
- and
- a linkage structure driven by the fluid driven actuator and coupled to the single cam pin.
A gripper jaw tip assembly which comprises:
- a jaw member having a rectangular recessed tip seat for receiving a workpiece holding tip;
- and
- a workpiece holding tip having a rectangular recessed portion that is complementarily shaped to the recessed tip seat so that recessed portions of the tip seat and workpiece holding tip can be interlocked together so as to abut one another.
