The beneficial effects of the utility model are: the structure cuts magnetorheological fluid by the relative motion between upper and lower magnetic pole
It cuts, achievees the purpose that inhibit zitterbewegung.
Detailed description of the invention
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute the restriction to the utility model.
Fig. 1 is damping device structural schematic diagram, and Fig. 2 is damping device diagrammatic cross-section.
Wherein: 1 is pedestal, and 2 be lower box, and 3 be downside magnetic pole, and 4 be center magnetic pole, and 5 be upper mounted plate, and 6 be upper magnetic pole,
61 be upper spacer, and 7 be connecting plate.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
As shown, a kind of be used for precision machined damping device structure, it include pedestal 1, lower box 2, downside magnetic pole
3, central magnetic pole 4, upper mounted plate 5, upper magnetic pole 6, connecting plate 7；The pedestal 1 is rectangle plate structure, 1 top edge of pedestal
Lower box 2 has been bolted, one layer of gasket is also equipped between the lower box 2 and pedestal 1；2 inside of lower box
Downside magnetic pole 3 is bolted, which is the hollow ring structure of fitting 2 medial surface of lower box, and downside
It is twined on magnetic pole 3 and is formed with coil；Central magnetic pole 4 has been bolted in 1 center of pedestal, the central magnetic pole 4 and downside magnetic pole 3
At a distance, it and is twined in central magnetic pole 4 and is formed with coil；Fixed plate 5 is the T-shaped plate part for cooperating 2 top of lower box
Structure, the corresponding downside 3 center cavity position of magnetic pole of the upper mounted plate 5 are provided with round recessed, have been bolted in groove
Magnetic pole 6；The upper magnetic pole 6 is the corresponding hollow cylindrical structure being inserted in downside magnetic pole 3 and 4 intermediate space of central magnetic pole, and on
There is certain interval between magnetic pole 6 and downside magnetic pole 3, central magnetic pole 4,6 center of upper magnetic pole has been bolted in fitting
The upper spacer 61 of 6 inside of fixed plate 5 and upper magnetic pole, which flushes with 5 bottom surface of upper mounted plate；Fixed plate
5 top surfaces are connected with L-type connecting plate 7 by screw and positioning pin.
When it is implemented, filled with magnetorheological in gap between the upper magnetic pole 6 and downside magnetic pole 3, central magnetic pole 4
Liquid.
When practical operation, after adding magnetorheological fluid vibration absorber, when carrying out turnery processing, once cutter vibrates,
By the middle supporting plate for driving lathe and the synchronous vibration therewith of connecting plate 7 being fixed thereon, so that upper magnetic pole 6 and downside magnetic pole
3, reciprocal relative motion is generated between central magnetic pole 4.After the coil in lower box 2 is powered, it is located at upper magnetic pole 6 and downside
Magnetorheological fluid between magnetic pole 3, central magnetic pole 4 in gap will generate magnetic rheology effect under magnetic fields, form two magnetic of connection
The chain or column structure of pole, so that the property of similar solid be presented.At this time upper magnetic pole 6 and downside magnetic pole 3, central magnetic pole 4 it
Between relative motion will to its chain, column structure generate shear action.With the increase of coil current, the shearing of magnetic rheological liquid
Yield strength will increase, and will also increase to the inhibition of the relative motion between upper magnetic pole 6 and downside magnetic pole 3, central magnetic pole 4
Greatly, therefore the vibration of the lathe tool moved with upper magnetic pole 6 is inhibited, has achieved the purpose that cut down and inhibit turning vibration.
