Manual robotic tool changer with rotating piston

摘要

A manually actuated robotic tool changer includes a first housing (12) having a generally cylindrical piston (16) with a central axis partially extending from the first housing, the piston being rotatable about the axis. A plurality of tabs (18) are disposed about the circumference of a portion of the piston extending from the first housing. A second housing (14) has a bore to receive a portion of the piston. A plurality of locking lugs (42) are disposed about the bore. The tool changer is manually actuated from an unlocked position wherein the piston assumes a position with respect to the first housing such that the extending portion of the piston may be moved within the bore with the tabs moving between the locking lugs, to a locked position wherein the piston is rotated with respect to the first housing such that the tabs move beneath the locking lugs to lock the first and second housings together.
