SYSTEM AND METHOD FOR STAKING AN ASSEMBLY OF COMPONENTS WITHCOMPENSATION FOR COMPONENT TOLERANCES

摘要

A novel method and system is provided for staking components in a mechanic al device to achieve a resulting staked device with at least one desired inter- component clearance independent of feedstock variations in the materials used to form the components. Variants are fabricated for at least one of the pair of stacking dies used in the staking press and the variant with an appropriate staking clearance is selected each time a batch of components changes. In this manner, variations between lots of feedstock materials used to form the components will not result in staked devices which suffer from lateral looseness or other stakin g results which do not meet the specifications for the device. In a second embodiment, devices are first staked in a conventional staking press and are then loaded into a clearance setting pres s which deforms at least a portion of the staked device to obtain the desired clearance. By carefully limiting the force with which the deformation is performed, the desired clearance can be obtained without requiring the batching of components in the manufacturing process.
