Description
Technical field
The present invention relates to engine detection equipment fields, and in particular to a kind of engine vibration-damping workbench.
Background technology
In the detection experiment of motorcycle engine, a set of fixture for engine installation suspension is needed, at present the folder
Tool is mainly made of, and the bottom bottom plate with the left and right fixing bracket for hanging engine on bottom plate for installation is fixed on
Be between plate and left and right fixing bracket with bolt fasten rigid attachment, and bottom plate be also rigid attachment on testboard, in this way
In engine working process, due to the vibration of engine, it will make to generate impact endurance test shock, and simultaneously between each rigid attachment component
Larger noise is generated, this most likely results in the damage of associated components and engine, and causes serious environmental noise pollution.
Invention content
It is vibrated to be rigidly connected when solving available engine detection the invention is intended to provide engine vibration-damping workbench
The problem of being also easy to produce noise pollution.
In order to achieve the above objectives, basic technology scheme of the invention is as follows：Engine vibration-damping workbench, including level-one platform
With two level platform, two level platform is detachably connected on the upper end of level-one platform, and two level platform includes loading plate and the distribution of rectangle
Damping column in four corners in loading plate bottom, level-one platform include pedestal and supporting table, what pedestal was arranged in parallel including two
Vertical support plate, is connected with lateral bottom plate between two support plates, and into matrix distribution, there are four damper cylinder, vibration dampings on bottom plate
Multiple vibration-damping sheets are vertically superimposed in cylinder, the middle part of vibration-damping sheet is equipped with pilot hole, and vibration-damping sheet includes upper wave plate and lower wave plate, upper ripple
Piece and lower wave plate are in corrugated plate shape, and the ripple on upper wave plate and lower wave plate is centered on pilot hole to external radiation, upper wave plate
Trough offset and be fixedly connected with the wave crest of lower wave plate；The top of damper cylinder is fixed with the top plate that middle part is equipped with via, via
In be equipped with mandril, pressing plate is fixed on mandril, pressing plate is between top plate and vibration-damping sheet；Supporting table is equipped with through-hole, mandril
Top be threaded through in through-hole.
The principle and advantage of this programme be：During practical application, level-one platform be used for two level platform provide bottom support and
Further vibration damping, two level platform are used to provide support and preliminary vibration damping to engine and its fixture.Loading plate is used for engine
Fixture is supported and transmits the vibration generated in engine detection process, and damping column is for being supported loading plate and tentatively
Vibration damping, for pedestal for providing whole support, supporting table is for installation support level-one platform and transmits vibration.Support plate is bottom plate
Support is provided and provides installation tie point for workbench, convenient for the placement of workbench.Bottom plate provides support for damper cylinder, and four subtract
Vibration cylinder is in vibration of the matrix distribution from four direction uniform pickup supporting table, and vibration-damping sheet weakens vibration for further absorbing.It leads
It is used to mandril is oriented to and be weakened the vibration in the middle part of vibration-damping sheet to hole, the upper wave plate of corrugated plate shape and lower wave plate are superimposed to be formed
The cavity of several smooth surfaces, vibration is transferred to after vibration-damping sheet divides reduction, while vibration-extrusion is upper and lower by several cavity structures
Wave plate so that upper and lower wave plate is mutually squeezed so that cavity deformation absorption vibration, vibrates the noise of generation in sky in same vibration-damping sheet
Back and forth fluctuation gradually weakens between cavity wall, and ripple is from pilot hole to external radiation so that the ripple of vibration-damping sheet is from edge guides to hole
Place is gradually intensive, and vibration wave can weaken faster on vibration-damping sheet, and effectiveness in vibration suppression is more preferable.Top plate prevents for limiting vibration-damping sheet
It is detached from out of damper cylinder, and mandril vibrates for connecting level-one platform and transmitting, and pressing plate is used to compress vibration-damping sheet and passes vibration
Vibration-damping sheet is passed, the top of mandril passes through through-hole to transmit vibration, and to support convenient for fixed level-one platform in contact supporting table
Position of the platform on pedestal carries out auxiliary restriction.The vibration generated in engine detection process first passes through the damping column of level-one platform
Vibration damping is carried out, the vibration after damping column vibration damping weakens passes to damper cylinder by mandril and supporting table, vibrates and leads in damper cylinder
The deformation and segmentation for crossing vibration-damping sheet are further weakened, and are finally absorbed by the process that vibration-damping sheet deformation is restored, are reached good
Effectiveness in vibration suppression, the noise that vibration generates is absorbed during vibration damping simultaneously by several cavitys in vibration-damping sheet, while vibration damping
With good erasure effect, the connection with certain domain of walker is formed between tooling when starting machine testing, is solved existing
There is the problem of being also easy to produce noise pollution vibrated that is rigidly connected when starting machine testing.
Preferred embodiment one, as a kind of improvement of basic scheme, upper wave plate in adjacent vibration-damping sheet, lower wave plate from top to bottom
Corrugation density is sequentially increased.Setting so that the vibration damping noise reduction cavity formed inside underlying vibration-damping sheet is more in this way, multiple
