A reconfigurable leak testing system is provided that includes a leak testing station and at least one off-shuttle cart removably attachable to the leak testing station. A fixture cartridge is translatable between the off-shuttle cart and the leak testing station. The fixture cartridge is configured to selectively couple with the leak testing station. The fixture cartridge includes an upper fixture, a lower fixture, and an actuatable testing feature. The fixture cartridge is configured to receive a part between the upper fixture and lower fixture. The actuatable testing feature is configured to contact the part. A closed volume is defined at least partially by the actuatable testing feature and the part.

Reconfigurable leak testing system

A reconfigurable leak testing system includes a leak testing station, an off-shuttle disposed adjacent to the leak testing station, and a fixture cartridge that is translatable between the off-shuttle and the leak testing station. The fixture cartridge is configured to selectively couple with the leak testing station and includes an upper fixture, a lower fixture, and a plurality of actuatable testing features. The fixture cartridge is configured to receive a part between the upper fixture and lower fixture, and the plurality of actuatable testing features are configured to contact the received part to create a closed volume adjacent the part, wherein the closed volume may be pressurized via a pressurized fluid, and examined for leaks.

A flexible fixture system for a CNC machine is coupled to a base fixture. The flexible fixture includes quick connects that connect with the base fixture in order to allow hydraulic fluid, air, and water to be communicated from the base fixture to the flexible fixture system. The flexible fixture system includes features operable to hold a workpiece within the CNC machine. The flexible fixture system is modular and may be swapped out for a different flexible fixture in order to allow other operations to be performed on the workpiece.
