Abstract
A robot hand tool linkage device includes a locking mechanism and an actuation shaft driven between a lock position and a release position. A piston moves an actuation shaft upward and downward to cam outward a plurality push rods urging outward a plurality arc-shaped locking members. The locking members are captured under an arcuate surface of a tool plate which is thereby attached. A resilient member engages an outer groove in each of the locking members to urge them inward. When the outward force on the locking members is released, the resilient member moves the locking members inward to reduce their combined diameter sufficiently to disengage from the arcuate surface, and thereby to release the tool plate.
