Systems and Assemblies Associated with a Tooling Joint

A system comprising:

• a transfer rail;
• and
• a plurality of arms coupled to the transfer rail, each arm having a plurality of joints, wherein a joint of the plurality of joints comprises:
• an electric motor having an output shaft,
• a clamp having a clamp shaft that is rotatably coupled to the output shaft of the electric motor,
• a gear that is rotatably coupled to the clamp shaft,
• a locking module comprising a piston and a lock spring applying a biasing force on the piston,
• at least one pawl movable by the piston, wherein (i) as the piston is actuated, the piston moves against the lock spring, allowing the at least one pawl to move away from the gear, and allowing the gear and the clamp shaft to rotate with the output shaft of the electric motor, and (ii) as the piston is unactuated, the lock spring biases the piston, causing the at least one pawl to move toward and engage the gear to lock the gear in position, thereby preventing the clamp shaft from rotating.

A method comprising:

• providing fluid to a locking module of a joint, thereby causing a piston of the locking module to move to an actuated position, allowing at least one pawl to disengage from a gear of the joint;
• sending a command signal to an electric motor of the joint, wherein the electric motor has an output shaft, wherein the joint has a clamp having a clamp shaft that is rotatably coupled to the output shaft of the electric motor, and wherein the gear is rotatably coupled to the clamp shaft such that the command signal causes the output shaft, the clamp shaft, and the gear to rotate;
• and
• discharging fluid from the locking module, causing a lock spring to return the piston to an unactuated position, thereby causing the piston to move the at least one pawl toward and engage the gear to lock the gear in position, preventing the clamp shaft from rotating.
