Abstract
A manufacturing process, such as that used for ultrasonic welding, employs a self-leveling fixture (20) including a base (12) and an operation stage (14) that are separated by leveling devices (16) and 18). The leveling devices include a centrally located spherical plane bearing (16) and one or more spring members (18) disposed about the periphery of the operation stage. In this way, the operation stage can react in response to pressure applied thereto complying to the applied pressure, thus providing a realistic self-leveling feature. After the pressure is removed, the return to a normal position via the spring action of spring (18).
