Description
Technical field
The present invention relates to cutter for milling machines fixture, especially relate to the pressure self-adjusting with vibration-damping function based on magnetic flow liquid
Joint cutter for milling machines 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
Adding under error, 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 milling 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 gravity compensator, chamber shell, pressure transducer, valve jacket, magnetic flow liquid, cage ring, bolt, pre-loading screw, end cap, live
Plug, solenoid, chuck forms.Being bolted between chamber shell, valve jacket, end cap, form a chamber, piston is arranged on chamber
Chamber interior, forms moving sets therewith；Piston has groove and grooved ring, and pressure transducer is arranged on inside grooves, solenoid around
Inside grooved ring；Chamber shell, valve jacket, end cap, piston form a cavity closed, and magnetic flow liquid is full of whole cavity, and passes through
Cage ring is isolated with solenoid；End cap is provided with screwed hole, and pre-loading screw coordinates with this screwed hole；Chamber shell is provided with applicable gravity
Compensator, chuck is connected with chamber shell.
The pressure self-adjusting with vibration-damping function based on magnetic flow liquid of the present invention saves the positive of cutter for milling machines 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 cutter for milling machines 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 cutter for milling machines fixture with vibration-damping function based on magnetic flow liquid, should
Device is mainly by gravity compensator 1, chamber shell 2, pressure transducer 4, valve jacket 5, magnetic flow liquid 6, cage ring 7, bolt 8, pretension
Screw 9, end cap 10, piston 11, solenoid 12, chuck 14 form.Chamber shell 2, valve jacket 5, asking of end cap 10 are connected by bolt 8
Connecing, form a chamber, piston 11 is arranged on chamber interior, forms moving sets therewith；Piston 11 has groove and grooved ring, pressure
Sensor 4 is arranged on inside grooves, and solenoid 12 is wound on inside grooved ring；Chamber shell 2, valve jacket 5, end cap 10, piston 11 form one
The cavity of individual closing, magnetic flow liquid 6 is full of whole cavity, and is isolated with solenoid 12 by cage ring 7；End cap 10 is provided with spiral shell
Pit, pre-loading screw 9 coordinates with this screwed hole；Chamber shell 2 is provided with applicable gravity compensator 1, and chuck 14 is connected with chamber shell 2.
Milling cutter 3 is extend into chuck 14 and chamber shell 12 inside positions, promote piston 11 to carry out by pre-loading screw 9
Pretension, logical certain electric current in solenoid 12, thus certain magnetic field intensity 13 is produced in space, magnetic flow liquid 6 place, make
Obtain magnetic flow liquid 6 and rheological phenomena occurs, so that piston 11 has certain shear yield stress, then rotate pre-loading screw
9 make it away from piston 11, it is ensured that the response speed of piston 11 and effectiveness in vibration suppression, are then turned on spindle motor and add workpiece
Work, now cutter is passed to external control system to the active force of piston 11 by pressure transducer 4 in real time, regulates electromagnetic wire in real time
Enclose the current intensity in 12 thus control magnetic flow liquid 6 Rheological strength, thus automatically change piston 11 and the pressure of handle of a knife is risen
To the effect of vibration damping, in the course of processing, reach whole machinery by being fixed on the gravity compensator 1 being suitable for above chamber shell 2
Device dynamic balancing purpose in motor process.
