Description
Technical field
The invention belongs to damping vibration attenuation technical field, and in particular to a kind of based on magnetic flow liquid extruding work
Vibration damping lathe tool.
Background technology
The self-excited vibration periodic vibration stable by the continuing for energy production in rest energy source.In the amplitude little phase
Between, vibrational energy fifty-fifty can be supplemented；During amplitude increases,DissipateEnergy composition, wrapped
It is contained in vibrational system, now supplementary energy reaches balance with the energy for dissipating and is close to certain amplitude
Vibration.Heartthrob, tremble, some periodic phenomenas seen in biology such as sexual cycle, have perhaps
It is self-excited vibration mostly.
Machine cut tremor is produce between cutter and workpiece in metal cutting process a kind of strong relative
Vibration, it belongs to self-excited vibration.Tremor can reduce crudy, affect machining accuracy, cause processing effect
Rate declines, therefore it is significant to study the technology of suppression cutting-vibration.Intellectual material magnetic flow liquid
Appear as suppressing cutting-vibration to provide new direction.Intellectual material magnetic flow liquid can be under externally-applied magnetic field
Moment becomes class solid from the liquid for flowing freely, and presents controllable yield strength, and this change is
It is reversible.Intellectual material magnetic flow liquid is used widely in building, automobile and other industries.
The content of the invention
It is an object of the invention to provide a kind of vibration damping lathe tool based on magnetic flow liquid extruding work, to solve
The problem proposed in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme：It is a kind of that work is extruded based on magnetic flow liquid
The vibration damping lathe tool of work, including lathe tool axle, magnetic rheological liquid, pole plate, magnet exciting coil, iron core, end cap and
Lower box, the left end of the lathe tool axle are fixed with disk, and the pole plate is embedded in the inside of lower box groove,
And pole plate empty set is in the outer rim of lathe tool axle, the Double layer iron of interference fit between the pole plate and end cap, is provided with
Core, the magnet exciting coil are wrapped on iron core, and the magnet exciting coil is set to four groups, the end cap
It is fixedly connected with lower box, the end cap is fixedly connected with lathe tool axle.
Preferably, upper box is provided with the outside of the pole plate.
Preferably, the upper box is distributed with regard to the axisymmetrical of lathe tool axle with the position of lower box.
Preferably, the other end of the magnet exciting coil is drawn from the open slot of upper box.
Preferably, the right-hand member of the lathe tool axle is fixed with lathe tool.
The technique effect and advantage of the present invention：The vibration damping lathe tool based on magnetic flow liquid extruding work is somebody's turn to do, is passed through
The magnetic rheological vibration damper of magnetic rheological liquid, pole plate, magnet exciting coil and iron core composition, can reduce metal
The strong Relative Vibration produced between cutter and workpiece in working angles；The present invention subtracts under different electric currents
The modal parameter of vibrating device can change, and so as to change the dynamic characteristic of system, suppress tremor, therefore
Design is analyzed to mode of the magnetic rheological vibration damper under different magnetic induction, can be effective for the later stage
Suppress vibration, find optimal Flutter Control strategy and lay the foundation.
