Description
Technical field
The present invention relates to a kind of 3D printer workbench vibration absorber, more particularly, to a kind of 3D based on magnetic rheology effect
Print machine worktable vibration absorber.
Background technology
With the fast development of science and technology, 3D printing technique is constantly ripe, and each colleges and universities and scientific research institution introduce
3D printer prints auxiliary spare part, brings great convenience to our scientific research personnel, teacher and classmates, while 3D
There are various unreliable factors during use in printer.Wherein, process of the 3D printer workbench in printing
It is middle that vibration even shake occurs, cause the precision of process component to reduce.There is the generation that many factors cause this vibration：Electricity
Machine rotates the vibration for causing workbench；Nozzle when table surface is walked due to caused by uneven surface workbench vibration or
Person shakes；Since the vibration on ground causes vibration of machine etc., the vibration source reactions of these factors vibration on the table or
Person's shake is all avoidable.For this avoidable vibration or shake, the present invention is using magnetic flow liquid as centre
Material, the characteristics of being worked using magnetic flow liquid under squeeze mode, produce damping force to reach vibration damping purpose.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of using this intellectual material of magnetic flow liquid as intermediate material, profit
The characteristics of being worked with magnetic flow liquid under squeeze mode produces damping force to reach the 3D based on magnetic rheology effect of vibration damping purpose
Print machine worktable vibration absorber.
In order to effectively weaken the oscillation phenomenon of 3D printer workbench at work, the present invention be come as follows it is real
Existing：A kind of 3D printer workbench vibration absorber based on magnetic rheology effect, the device are in extrusion die using magnetic flow liquid
The characteristics of stable damping force can be produced when working under formula, main parts size include shell body, micrometer adjusting screw, heat block, rubber bullet
Property pad, workbench, inner housing, trip bolt, temperature sensor, magnetic flow liquid, end cap, rubber cage ring, electromagnetic coil.Shell
Body is provided with groove, and electromagnetic coil is wound on inside groove, and blend rubber cage ring isolates it with magnetic flow liquid；Inner housing and end cap
Connect to form a sealing space by holding screw, heat block and temperature sensor are installed on inside this closed chamber；Work
Platform is installed on above rubber mat, is placed in above inner housing, the horizontal level of workbench is fixed and adjusted by micrometer adjusting screw；
Shell body inner bottom surface, rubber cage ring inner wall, end cap bottom surface form a movable closed chamber, and magnetic flow liquid is filled in this
Inside sealed chamber.Shell body, workbench, inner housing, end cap all use permeability extremely low and the less aluminum alloy materials of density,
Only have magnetic flow liquid to have higher magnetic conductivity in whole device, be so conducive to magnetic field caused by electromagnetic coil and be completely covered on
Space where magnetic flow liquid is so as to obtain a uniform magnetic field.In addition, magnetic flow liquid is developed using Lord companies of the U.S.
Model MRF-132LD magnetic flow liquid, the magnetic flow liquid of such model has good Magnetostrictive Properties.
A kind of good effect of 3D printer workbench vibration absorber based on magnetic rheology effect of the present invention is：
A kind of vibration absorber is added on the basis of original 3D printer workbench is not provided with vibration damping, this vibration absorber make use of
Magnetic flow liquid, which is operated under squeeze mode, can produce the characteristics of stablizing damping force, effectively act as the effect of vibration damping.The device
It is working stability, reliable with simple in structure, compact, the characteristics of reaction time is exceedingly fast.
Brief description of the drawings
Fig. 1 shows for a kind of operating mode principle of the 3D printer workbench vibration absorber based on magnetic rheology effect of the present invention
It is intended to.
