Giant magnetostrictive material-driven intelligent boring rod

Abstract

The invention discloses a giant magnetostrictive material-driven intelligent boring rod, which comprises a static pressure boring machine spindle, wherein a fixed seat is fixedly arranged on the static pressure boring machine spindle; an upper excitation coil bracket and a lower excitation coil bracket are fixedly arranged on the fixed seat respectively; an upper giant magnetostrictive rod and a lower giant magnetostrictive rod are fixedly arranged on the upper and lower excitation coil brackets respectively; excitation coils are correspondingly wound outside the upper and lower giant magnetostrictive rods on the upper and lower excitation coil brackets respectively; a boring rod is fixedly connected between the upper and lower giant magnetostrictive rods; a cutting tool is fixedly connected to the front end of the boring rod. The giant magnetostrictive material-driven intelligent boring rod is reasonable and reliable in structure; the giant magnetostrictive rods can extend and contract under the action of a magnetic field to drive the boring rod to be axially deflected to radially feed the cutting tool for the boring machining of an irregularly-shaped pinhole.

Description

technical field [0001] The invention relates to the technical field of boring bars for boring machines, in particular to an intelligent boring bar driven by giant magnetostrictive materials. Background technique [0002] In the current machining scheme for special-shaped pin holes, the piezoelectric ceramic material has fast response speed and sensitive boring bar action, but when the piezoelectric ceramic rotates with the spindle, it is difficult to supply power, and the brush contact method is used, which is difficult to meet the requirements of high-speed boring. . As a new type of intelligent material, giant magnetostrictive materials have the characteristics of large driving force, large expansion coefficient, high power density, fast response speed, and high controllable precision, and have been widely used. Contents of the invention [0003] The purpose of the present invention is to provide an intelligent boring bar driven by giant magnetostrictive material. U...
