Abstract

The invention discloses a deep hole machining magnetorheological liquid flutter suppressing device. The deep hole machining magnetorheological liquid flutter suppressing device comprises a supportingsleeve, an electromagnetism generation mechanism, an end cover and a magnetorheological liquid material. The electromagnetism generation mechanism is arranged in the supporting sleeve and comprises electromagnetic coils and a hollow electromagnet core, two annular grooves are formed in the hollow electromagnet core, the electromagnetic coils are wound in the grooves, two sets of through holes arefurther symmetrically formed in the middle of the hollow electromagnet core, each set of through holes comprise two injection holes, internal threads are tapped in the injection holes, a through holecorresponding to a machining part is formed in the middle of the end cover, and the rear end of the supporting sleeve is connected with the end cover through a bolt. According to the deep hole machining magnetorheological liquid flutter suppressing device, squeezing and shearing modes are adopted, the supporting rigidity and the damp feature of a cutting system are changed through the feature thatthe elastic modulus changes along with changing of a magnetic field, the controllability is good, responding is fast, and a good vibration reduction effect can be achieved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a chatter suppressing device for magnetorheological fluid in deep hole processing. Background technique [0002] Deep hole processing has always been an important part of mechanical manufacturing technology, and it is also one of the difficulties. Among them, hole processing has accounted for about one-third of all machining, and about 40% of these hole processing is for deep hole processing. The so-called deep hole generally refers to a hole whose ratio of hole depth to hole diameter is greater than 5. Deep hole processing technology was first used in the production of military equipment, such as: gun barrels, gun barrels, etc. At the same time, this technology is in a closed development because it involves the military field. With the continuous development of economy and technology, deep hole processing technology has gradually turned to civilian applications, mainly use...
