Description
Technical field
The present invention relates to lathe tool fixture, especially relate to the pressure self-adjusting with vibration-damping function based on magnetic flow liquid
Joint lathe tool fixture.
Background technology
Along with development and the progress of society, not only the overall qualities of people are had higher requirement, and right
Our processing manufacturing industry proposes the requirement more modernized, it is desirable to product is constantly toward light, small and exquisite and powerful etc.
Direction is developed, and to be the machining accuracy to machining equipment after all propose higher level the wanting of this developing direction
Ask.It would therefore be desirable to installation accuracy when improving processing and manufacturing precision and the parts installation of parts.The most many enterprises
The processing and manufacturing of the product of industry has a set of fairly perfect full-automatic or semiautomatic production equipment, which greatly enhances product
Production efficiency, but practice teach that the quality of product that such production line produced be not each and every one all as
, defect rate also needs to reduce further, and the reason producing this situation has a lot, one reason for this is that automated production
On line and itself there is precision problem, this root causing precision problem is mainly in lathe process of manufacture is produced
Raw vibration, provided that a kind of jig, adds magnetic flow liquid (a kind of intellectual material), it is possible to perception inside this fixture
The change of outside environment and if making suitable response, then just can be run by our the most set parameter, this
Once can significantly reduce due to the external vibration impact on tool sharpening precision；This intellectual material has vibration damping and delays
The function of punching, so can absorb the mechanical vibration of a part, thus reduce the plant equipment caused by vibration
Mismachining tolerance, and the structure that this tool mounting has is simple, easy to process, the function of response rapidly (Millisecond).
Summary of the invention
The technical problem to be solved in the present invention is to provide the pressure self-adjusting joint car with vibration-damping function based on magnetic flow liquid
Bed tool mounting.Device has the special feature that and is: according to the processed parts active force to cutter, by pressure transducer by power
Signal feeds back to coil, thus the current intensity being automatically adjusted in coil reaches to control magnetic current and liquid flow intensity adjustable, changes magnetic
The shear yield stress of rheology liquid, thus the active force that regulating piston is to handle of a knife, and then absorb the mechanical vibration of a part, cut down
The mismachining tolerance of the plant equipment caused by vibration；And the structure that this tool mounting has wants simple, processing side
Just, the function of response (Millisecond) rapidly.
In order to effectively realize function as above and feature, the present invention realizes as follows: this device
Mainly by pre-loading screw, bolt, chamber shell, piston, solenoid, cage ring, valve jacket, magnetic flow liquid, end cap, bearing, pressure
Sensor.Being bolted between chamber shell, valve jacket, end cap, form a chamber, piston is arranged on chamber interior, therewith shape
Become moving sets；Piston has groove and grooved ring, and pressure transducer is arranged on inside grooves, and solenoid is wound on inside grooved ring；Chamber
Shell, valve jacket, end cap, piston form a cavity closed, and magnetic flow liquid is full of whole cavity, and by cage ring and electromagnetic wire
Circle isolation；Chamber shell is provided with screwed hole, and pre-loading screw coordinates with this screwed hole.
The pressure self-adjusting with vibration-damping function based on magnetic flow liquid of the present invention saves the positive of lathe tool fixture
Effect is: according to the processed parts active force to cutter, by pressure transducer, force signal is fed back to coil, thus
The current intensity being automatically adjusted in coil reaches to control magnetic current and liquid flow intensity adjustable, and the shear yielding changing magnetic flow liquid should
Power, thus the active force of regulating piston team handle of a knife, and then absorb the mechanical vibration of a part, reduce caused by vibration
The mismachining tolerance of plant equipment；And the structure that this tool mounting has is simple, easy to process, response is rapid (Millisecond)
Function.
Accompanying drawing explanation
Fig. 1 is the internal junction of the present invention pressure self-adjusting joint lathe tool fixture with vibration-damping function based on magnetic flow liquid
Structure principle schematic.
Detailed description of the invention
The present invention is described in more detail with embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, the present invention pressure self-adjusting joint lathe tool fixture with vibration-damping function based on magnetic flow liquid, should
Device is mainly by pre-loading screw 1, bolt 2, chamber shell 3, piston 4, solenoid 6, cage ring 7, valve jacket 8, magnetic flow liquid 9, end
Lid 10, bearing 12, pressure transducer 13.Connected by bolt 2 between chamber shell 3, valve jacket 8, end cap 10, form a chamber 14,
It is internal that piston 4 is arranged on chamber 14, forms moving sets therewith；Piston 4 has groove and grooved ring, and pressure transducer 13 is arranged on recessed
Inside groove, solenoid 6 is wound on inside grooved ring；Chamber shell 3, valve jacket 8, end cap 10, piston 4 form a cavity closed, magnetic current
Become liquid 9 and be full of whole cavity, and isolated with solenoid 6 by cage ring 7；Chamber shell 3 is provided with screwed hole 15, pre-loading screw 1 with
This screwed hole 15 coordinates.
Lathe tool 11 is placed on bearing 12 and positions, promote piston 4 to carry out pretension by pre-loading screw 1, toward electromagnetism
Logical certain electric current in coil 6, thus certain magnetic field intensity 5 is produced in space, magnetic flow liquid 9 place so that magnetic flow liquid 9
Raw rheological phenomena, so that piston 4 has certain shear yield stress, then rotates pre-loading screw 1 and makes it away from piston
4, it is ensured that the response speed of piston 4 and effectiveness in vibration suppression, it is then turned on spindle motor and workpiece is processed, now pressure sensing
Cutter is passed to external control system to the active force of piston 4 by device 13 in real time, in real time the current intensity in regulation solenoid 6
Thus control magnetic flow liquid 9 Rheological strength, thus automatically change piston 4 and the pressure of handle of a knife is played the effect of vibration damping.
