Embodiment Construction

[0016] As shown in the accompanying drawings, the present invention is mainly composed of two parts: a rare earth giant magnetostrictive bidirectional output transducer and a planar eight-link fully flexible micro-displacement amplifying mechanism. The rare earth giant magnetostrictive bidirectional output transducer includes three parts: telescopic drive, preload and cooling. The specific structure: there are 6 through holes in the circumferential direction at the left and right ends of the shell 21 at a distance of 30 mm from the end face, for the coil skeleton 18 to be fastened. Screws 23 are fixed inside the housing 21 . A cooling oil hole with threads is respectively provided on the side walls of the left and right ends of the coil bobbin 18, and a cooling oil diversion port 6 and a cooling oil confluence port 13 are respectively opened on the cooling oil hole 20 mm away from the outlet for the cooling oil to flow into For outflow use, one oil pipe joint 10 is installed o...

Abstract

The invention belongs to the field of precision machining and precision control, and particularly relates to a rare-earth giant-magnetostrictive energy converter with a flexible hinge micro-displacement compound operational amplifier. The rare-earth giant-magnetostrictive energy converter comprises a frame, a rare-earth giant-magnetostrictive bidirectional output energy converter body and a plane eight-bar linkage type full-flexible micro-displacement amplifying mechanism. The rare-earth giant-magnetostriction bidirectional output energy converter body and the plane eight-bar linkage type full-flexible micro-displacement amplifying mechanism are arranged on the frame. The design of bidirectional output of the rare-earth giant-magnetostrictive energy converter is adopted, the dynamic periodic axial acting force of the energy converter can be balanced basically, additional vibration can be greatly eliminated, the fatigue life of the energy converter can be effectively prolonged, and the energy conversion efficiency of the energy converter can be effectively improved. In addition, a lever-and-mechanism type cascade micro-displacement flexible hinge operational amplifier mechanism is adopted, internal and external two-stage amplification is carried out, and the moving sensitivity and the resolution ratio are high.

Description

technical field [0001] The invention belongs to the field of precision machining and precision control, and in particular relates to a micro-displacement composite op-amp telescopic transducer with a rare-earth giant magneto-induced flexible hinge. Background technique [0002] Transducers based on electro-magnetic-mechanical-thermal multi-physics energy conversion functional materials are currently the most scientifically significant and promising transducers in the field of electrical engineering. Among them, the most dynamic and representative ones are: temperature-controlled or magnetically-controlled shape memory alloy transducers, piezoelectric ceramic transducers, and giant magnetostrictive transducers. In recent decades, the vast majority of transducers are made of piezoelectric materials, which have the advantages of high electromechanical coupling coefficient, relatively small high-frequency dielectric loss, low cost, and easy preparation. However, compared with p...
