Description
Technical field
The utility model belongs to damper technical field more particularly to a kind of table model high speed centrifuge damper.
Background technique
It is frequently necessary to use supercentrifuge in medical treatment detection, the principle of supercentrifuge is high using centrifuge rotor
Speed rotates the powerful centrifugal force generated, the sinking speed of particle in accelerating liquid, sedimentation coefficients different in sample and buoyancy
The substance of density separates, due in centrifuge apparatus rotary-tray and gyrator etc. inevitably go out in the fabrication process
Now about cooperation and Mass Distribution lopsidedly problem, therefore can occur seismism at work, the vibration of centrifuge is weighing apparatus
Measure the one of the important signs that of centrifuge performance superiority and inferiority.
Supercentrifuge damping is divided into active vibration damping and passive energy dissipation.Active vibration damping is exactly the work by centrifuge in the design
Make the critical speed that revolving speed much avoids rotary system, this needs producer to determine when designing production.Passive energy dissipation be exactly with
The vibration that the damper of various types will likely generate is separated with rack.At present the various dampers that occur on the market can with or it is more
Or cushioning effect is realized less, more dampers have to be designed and manufacture, to meet different types of centrifuge.
Utility model content
The utility model provides a kind of table model high speed centrifuge damper, it is intended to go out when reducing table model high speed centrifuge work
Existing seismism.
The utility model is realized in this way a kind of table model high speed centrifuge damper, including lower rubber mat, glued on lower rubber mat
Bottom plate to be tied, external damping is connected on bottom plate, external damping is connect with interior damping by little spring, it is bonded with rubber mat in interior damping,
It is installed with bolt in interior damping, nut is equipped between bolt and interior damping, is connected between interior damping and bottom plate by big spring.
Further, the inner wall of external damping is equipped with pattern draft.
Further, the quantity of little spring is four, is symmetrically distributed in the surrounding of interior damping.
Further, it is connected with nut on bolt, is equipped with washer between screw bolt and nut.
The beneficial effects of the utility model are: interior damping is connected with bottom plate by big spring, interior damping and external damping pass through
Little spring connection, interior damping have freedom degree, and the pallet of centrifuge is fixedly connected by bolt with damper, and pallet is in rotary course
Middle drive damper rotation will appear non-equilibrium state in rotation since the quality of pallet can not be uniformly distributed, in order to
Reach damping effect, interior damping can occur the phenomenon that inclination distortion in imbalance in external damping, as far as possible turn pallet
Dynamic process keeps balancing again, to reduce the seismism occurred when table model high speed centrifuge work, effectively to desk-top
Supercentrifuge carries out damping.
Detailed description of the invention
Fig. 1 is a kind of main view of table model high speed centrifuge damper provided by the utility model.
Fig. 2 is a kind of top view of table model high speed centrifuge damper provided by the utility model.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
As shown in Figure 1-3, interior damping 2 and bottom plate 7 are connected by big spring 9, interior damping 2 and external damping 8 pass through little spring
10 connections, interior damping 2 have freedom degree, and the pallet of centrifuge is fixedly connected by bolt 4 with damper, and pallet is in rotary course
Damper rotation is driven, since the quality of pallet can not be uniformly distributed, will appear non-equilibrium state in rotation, in order to reach
To damping effect, interior damping 2 can occur the phenomenon that inclination distortion in imbalance in external damping 8, as far as possible turn pallet
Dynamic process keeps balancing again, to reduce the seismism occurred when table model high speed centrifuge work, effectively to desk-top
Supercentrifuge carries out damping.
Embodiment one
As shown in Figure 1-3, the utility model provides a kind of table model high speed centrifuge damper, including lower rubber mat 1, lower glue
Bottom plate 7 is bonded on pad 1, external damping 8 is connected on bottom plate 7, and the inner wall of external damping 8 is equipped with pattern draft, external damping 8 and interior damping
2 are connected by little spring 10, and the quantity of little spring 10 is four, are symmetrically distributed in the surrounding of interior damping 2, are bonded in interior damping 2
There is upper rubber mat 5, bolt 4 be installed in interior damping 2, nut 6 is equipped between bolt 4 and interior damping 2, is connected with nut 6 on bolt 4,
It is equipped with washer 3 between bolt 4 and nut 6, is connected between interior damping 2 and bottom plate 7 by big spring 9.
Embodiment two
In use, removing nut 6 and washer 3, pallet is placed on upper rubber mat 5, bolt 4 is made to pass through tray bottom, then
Washer 3 and nut 6 are successively loaded onto and tightened, starting centrifuge work, the pallet rotation of centrifuge, pallet is in rotary course
Damper rotation is driven, due to the mass unbalance of pallet, therefore will appear non-equilibrium state in rotation, at this point, being mounted in extrernal resistance
The interior damping 2 of 8 inner ring of Buddhist nun will appear the phenomenon that inclination and distortion, with the imbalance of offset tray rotation process.
Interior damping 2 and bottom plate 7 are connected by big spring 9, and interior damping 2 and external damping 8 are connected by little spring 10, interior damping
2 have freedom degree, and the pallet of centrifuge is fixedly connected by bolt 4 with damper, and pallet drives damper to turn in rotary course
It is dynamic, since the quality of pallet can not be uniformly distributed, it will appear non-equilibrium state in rotation, in order to reach damping effect,
Interior damping 2 can occur the phenomenon that inclination distortion in imbalance in external damping 8, protect pallet rotation process again
Maintain an equal level weighing apparatus, thus the seismism that occurs when reducing table model high speed centrifuge work, effectively to table model high speed centrifuge into
Row damping.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
