Hydraulic tooling fixture

摘要

A tooling fixture includes a plurality of cylinders in a module fitted with pistons in which a portion thereof extends from the surface of the module. The cylinders are connected with a fluid source by a control valve assembly. The control valve assembly controls the amount of fluid to enter the cylinders in order to raise the pistons until a portion thereof are in contact with and support a workpiece. Once all of the pistons are in contact with and are fully supporting the workpiece, the fluid pressure is stabilized, maintaining the pistons at their set heights.Once the pistons are desired to be lowered, the valve assembly opens and the fluid can freely exit the cylinders and retract the pistons back into the module.
