Magnetostrictive driver with water-cooled plant and the forming method of its screw flat tube

Abstract

The present invention relates to mechanical technology and is one kind of driver based on super-magnetostrictive material. The driver consists of magnetostrictive rod, front magnetic pole end cap, back magnetic pole end cap, exciting winding, micro displacement output head, casing, fixed end cap, front end cap, spring, winding tap, flat spiral pipe, water inlet pipe and water outlet pipe. The water cooler of the present invention is formed through inserting one end of some metal pipe into positioning hole of spindle, installing rolling tool onto tool carrier, adjusting the lathe to the pitch of the flat spiral pipe and starting the lathe to complete the extruding formation of the flat spiral pipe. The present invention has simple structure and high reliability and can maintain constant temperature of the magnetostrictive rod.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a driver based on giant magnetostrictive materials. Background technique [0002] Magnetostriction is the phenomenon that an object will elongate and shorten along the direction of magnetization under the action of a magnetic field. Materials having magnetostrictive properties have been discovered in many cases. In recent years, reports on the development and application of magnetostrictive materials mainly refer to Terfenol-D (product of the United States). Terfenol-D is a rare earth alloy of iron (Fe), terbium (Tb) and dysprosium (Dy). The most ideal and most valuable magnetostrictive material for promotion and application. Often referred to as giant magnetostrictive materials. [0003] Terfenol-D is a kind of intelligent material. Compared with other intelligent materials, the driver made of it has the characteristics of large load capacity, large deformation, fast response...

AI Technical Summary

Problems solved by technology

[0013] There are two problems in this error elimination measure: 1) it increases the volume of the driver, which is not applicable when the design space is limited; , material elastic modulus, etc.), it is difficult to achieve the ideal compensation effect

[0014] ② For high-power, ultra-high-precision magnetostrictive drives, the aforementioned methods cannot completely solve the problem

[0016] The disadvantage of the water jacket cooling method is that the structure is relatively complicated, and there are six parts in total, all of which are connected by welding.

If there is leakage, a short circuit will occur
