Description
Technical field
The utility model relates to Precision Machining fields, more particularly to a kind of half active power damping boring bar structure.
Background technique
Chatter phenomenon in engineering goods cutting process is the key factor for restricting machining accuracy and improving, wherein
Boring be it is a kind of with cutter come the turning process of expanded hole, belong to half roughing or finishing scope, the flutter in Boring Process
It is the strong self-excited vibration generated between workpiece and cutter in process.In order to solve this problem, generally using built-in
Power vibration damping boring bar, but built-in power vibration damping boring bar is of limited application, and only just has in certain specific operations and significantly subtracts
Vibration effect, vibration damping are unsatisfactory.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of half active power vibration damping boring is provided
Rod structure, the rigidity changed by magnetorheological fluid by externally-applied magnetic field and damped coefficient change boring bar dynamic characteristic to reach
Purpose, to realize the effect of vibration damping.
A kind of half active power damping boring bar structure that in order to achieve the above purposes, the technical solution adopted by the utility model is:,
It include boring bar, iron core, plug, cutter head, coil, rubber bushing, magnetism-isolating loop；The boring bar is cylinder boring bar, the boring bar

There are certain intervals between the iron core lateral surface and blind hole medial surface；The boring bar blind hole is equipped with T shape circle in iron core endface
Column plug, which is connect by screw thread with boring bar, and gasket is provided between plug and iron core, plug and boring bar end face it
Between be provided with washer；The plug end face is fixedly connected with cutter head；Coil is installed in the middle part of the iron core lateral surface, outside the coil
Side is provided with one layer of magnetic shield；It is provided with annular groove on the outside of the iron core both ends, circular rubber bushing is installed in annular groove；It is described
Magnetism-isolating loop is fixedly connected between rubber bushing and boring bar blind hole medial surface.
Preferably, filled with magnetorheological fluid in gap between on the inside of the iron core, coil and boring bar blind hole.
The beneficial effects of the utility model are: the rigidity and damped coefficient that are changed by magnetorheological fluid by externally-applied magnetic field,
Come achieve the purpose that change boring bar dynamic characteristic, to realize the effect of vibration damping.
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 boring bar structural schematic diagram.
Wherein: 1 is boring bar, and 2 be iron core, and 3 be plug, and 31 be gasket, and 32 be washer, and 4 be cutter head, and 5 be coil, and 6 are
Rubber bushing, 7 be magnetism-isolating loop.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
As shown, a kind of half active power damping boring bar structure, includes boring bar 1, iron core 2, plug 3, cutter head 4, line
Enclose 5, rubber bushing 6, magnetism-isolating loop 7；The boring bar 1 is cylinder boring bar, which is provided with a T shape cylinder indent
Blind hole, and blind via bottom is tapered surface；It is set with cylinder iron core 2 in 1 blind hole of boring bar, in 2 lateral surface of iron core and blind hole
There are certain intervals between side；1 blind hole of boring bar is equipped with T shape cylinder plug 3 in 2 endface of iron core, which passes through
Screw thread is connect with boring bar 1, and gasket 31 is provided between plug 3 and iron core 2, and plug 3 and boring bar are provided with pad between 1 end face
Circle 32；3 end face of plug is fixedly connected with cutter head 4；Coil 5 is installed in the middle part of 2 lateral surface of iron core, 5 outside of coil
It is provided with one layer of magnetic shield；It is provided with annular groove on the outside of 5 both ends of iron core, circular rubber bushing 6 is installed in annular groove；It is described
Magnetism-isolating loop 7 is fixedly connected between rubber bushing 6 and boring bar blind hole medial surface.
When it is implemented, filled with magnetorheological fluid in gap between on the inside of the iron core 2, coil 5 and boring bar 1 blind hole.
When practical operation, iron core 2 also acts as the effect of damping block, and when boring bar 1 vibrates, iron core 2 also vibrates therewith, absorbs
The energy of vibration reaches vibration damping purpose；Why rubber bushing 6 is installed again in magnetism-isolating loop 7, buffering work mainly is played to iron core 2
With, be equivalent to the effect of metal spring, while rubber bushing 6 also act as a support iron core 2 and avoid iron core 2 in vibration with
The collision of magnetism-isolating loop 7, eliminates noise.
