Flexible leak test apparatus and method

A flexible leak test apparatus for leak-testing workpieces in a workstation wherein said workpieces have multiple geometric configurations with at least one internal cavity and at least one aperture leading therefrom, comprising:

• a plurality of leak test fixtures adaptable to receive said workpieces having different geometric configurations, and said leak test fixtures having a bottom portion and a top portion;
• means for shuttling said plurality of leak test fixtures in and out of said workstation;
• a robotic arm for loading and unloading said workpieces into said bottom portion of said leak test fixtures while in said at least one workstation;
• said top portion of said leak test fixtures removably engaging said bottom portion of said leak test fixtures when said workpieces are loaded in said bottom portion of said leak test fixtures;
• said plurality of leak test fixtures having at least one linear actuator connected thereto, and said at least one linear actuator having a sealing device connected thereto for automatically sealing said at least one aperture in said workpieces;
• said leak test fixtures in communication with a pressurized fluid source wherein said pressurized fluid source sealedly connects to said internal cavity of said workpieces;
• and
• a monitoring system having at least one sensor for measuring pressure in said internal cavity of said workpieces, and a computer in connection with said at least one sensor for interpreting measurements from said at least one sensor in determining whether said workpieces are leaking.
