ABSTRACT:
A robotic tool changer having a master unit and a tool unit adapted to be coupled together. Movably mounted in the master unit of the robotic tool changer is a piston that is movable between locked and unlocked positions. The piston includes a contact area having an unlocking surface, a failsafe surface and a locking surface. Also provided is a series of rolling members contained within a retention area that are actuated by the piston to lock the master unit to the tool unit. For example, the piston engages the rolling members and urges them into a locked relationship with a bearing race that forms a part of the tool unit. To prevent the inadvertent or accidental movement of the piston from the locked position to the unlocked position, the piston is provided with a retarding surface generally disposed between the locking surface and the unlocking surface on the piston for retarding the movement of the piston as the piston moves from the locked position to the unlocked position.
