The invention discloses a super magnetic induced shrinkage or elongation driving device with a semi-rhombus two-connecting-rod displacement output mechanism. The driving device comprises a pair of rod type super magnetic induced shrinkage or elongation drivers, a channel steel shaped frame and the semi-rhombus two-connecting-rod displacement output mechanism; and the semi-rhombus two-connecting-rod displacement output mechanism comprises a pair of driving rods, a pair of connecting rod supports, a left connecting rod, a right connecting rod and an output rod. The driving device can drive devices precisely; output displacement of the super magnetic induced shrinkage or elongation drivers in the horizontal direction is converted to the vertical direction, the defect that output displacement is in only one direction can be overcome, and the application range of the super magnetic induced shrinkage or elongation drivers is broadened; the size of the output displacement can be adjusted; and the driving device can be applied to occasion of low-displacement precise driving, and the displacement of the drivers can be controlled accurately.
Description
technical field [0001] The invention belongs to the technical field of precision drive control of small-stroke devices, and relates to a giant magnetostrictive drive device with a semi-rhombic two-link displacement output mechanism. Background technique [0002] Giant Magnetostrictive Material (Giant Magnetostrictive Material) is named because its magnetostriction coefficient is much higher than that of ordinary ferromagnetic materials. It is another type of electrical energy-mechanical energy conversion material that has attracted widespread attention after piezoelectric ceramic materials. Giant magnetostrictive materials have the advantages of small driving voltage, large output displacement, fast response speed and no fatigue failure, etc., and have broad application prospects in high-precision, high-speed and heavy-duty driving. Among them, the giant magnetostrictive actuator with rod-shaped giant magnetostrictive material as the core is the most basic device for the app...
