Base plate design for reducing deflection of suspension assembly by swaging

摘要

Techniques for coupling a suspension assembly to an actuator arm is provided. The base plate includes a metal member and a swaging boss formed by the metal member. At least one slot disposed in the swaging boss to distribute stress and deformation of the swaging boss during a swaging process. The base plate couples to the actuator arm via the swaging boss. A method for coupling a base plate to an actuator arm includes forcing first and second swage balls through a swage hole of the base plate. A diameter of the first swage ball is greater than the diameter of the swage hole, and a diameter of the second swage ball is greater than the diameter of the first swage ball. The swage hole is shaped by a swaging boss, which swaging boss includes at least one slot.
