Abstract
A magnetostrictive clamping device which includes first and second arm members having respective first and second end portions. The first and second arm members are interconnected to permit relative movement between the first and second end portions between a first position in which the first and second end portions are spaced apart and a second position in which the first and second end portions are spaced closer together. An actuator is included for causing relative movement between the first and second arm members from the first position to the second position. The actuator has a drive element made from a magnetostrictive material. An electromagnetic field extends through at least a portion of the drive element. The drive element is changeable between a first shape when in the absence of the electromagnetic field and a second shape when in the presence of the electromagnetic field.
