SPRING MECHANISM FOR POWER DEVICE

摘要

A spring mechanism for an electromagnetic drive unit converts or translates the movement and/or actuation of the electromagnet into a desired movement of the workpiece and enables simple and efficient tuning of the workpiece movement. The spring mechanism includes a housing, a spring connected to the housing, wherein at least a section of the spring is movable with respect to the housing, a drive shaft that includes a first end having a magnet and a second end for attachment to a workpiece, and an adjustable tuning element connecting the drive shaft to the movable portion of the spring. In one embodiment, the spring may be a flat spring, and the movable section may be a positioned between a pair of cutouts defined in the spring. In one embodiment, the adjustable tuning element is connected to the spring such that the adjustable tuning element places the movable portion of the spring under a degree of tension.
