TEST ASSEMBLY FOR MACHINE TOOL HAVING HYDRAULIC PALLET ASSEMBLIES

摘要

A machine tool has an array work stations which includes a plurality of machining stations. A plurality of hydraulic pallet assemblies are provided to hold workpieces to be machined. The hydraulic pallet assemblies are movable along a main track which extends through the work stations. Each of the hydraulic pallet assemblies includes hydraulic actuators which operate clamps to grip a workpiece. A test station is disposed to one side of a path of movement of the hydraulic pallet assemblies between the various work stations. A motor at the test station is operable to move a pallet assembly from the main track to a secondary track located at the test station. A connector assembly at the test station connects hydraulic fluid pressure with the hydraulic pallet assembly to operate the clamp assemblies under the same hydraulic pressure that they are actuated at a work station.
