The component component of structure all be cylindrical except that awl pole (2) is, and awl pole (2) be conical, is connected with cylinder cap 1 (1) and places inner chamber 1 (51) in and form the taper hole cooperation with the centre bore of cylinder cap 2 (7), packs the clay elastomer in the inner chamber 1 (51), and inert gas or air are packed to inner chamber 2 (52), and cylinder cap through being equipped with sealing device (4) 1 (1), cylinder cap 3 (8) and casing (5), one cylinder body (3) spiro union component seal up wholly. The utility model provides a high strength, shock -resistant, the safe buffer function at the other work piece of big heavyweight can be realized to anti structural distortion's elastic damping body shock attenuation buffer damper ware to satisfy the stable performance, long service life's requirement.

Description

Cone bar mutative damp antivibrator
Technical field
This utility model relates to a kind of cone bar mutative damp antivibrator, and the internal clay elastomer filled therein is a kind of compressible semifluid macromolecular material.
Background technology
In recent years, development along with clay elastomeric technology, elastic colloid damping, buffering antivibrator is widely used in the fields such as metallurgy, chemical industry, building, transportation and nuclear industry gradually, along with China's industry develops to " heavy duty, quick, safety " direction, the safety buffer device being suitable for big weight classes workpiece has good market prospect.
Elastic colloid damping, buffering antivibrator is the characteristic of high compression highly energy-consuming specific to this special media of clay elastomer, has the unrivaled advantage of other safety device in safe buffering field. But the elastic colloid damping, buffering damper structure having in the market cannot meet the safe buffering function of big weight classes workpiece, the structural strength that reason is current is not enough in use avoid self damage and inefficacy. Therefore one of the emphasis link of elastic colloid damping, buffering antivibrator that the anti-pressure ability of structure is big weight classes workpiece is improved.
Summary of the invention
According to background technology, the purpose of this utility model is in that to provide a kind of high intensity, shock-resistant, the elastic colloid damping, buffering antivibrator of anti-malformation, the safe buffering function at big weight classes workpiece can be realized, and meet stable performance, the requirement of long service life.
To achieve these goals, this utility model is achieved through the following technical solutions: adopting clay elastomer is buffer medium, mainly by cylinder cap (1), and cone bar (2), cylinder body (3), sealing device (4), housing (5), housing cavity 1 (51), housing cavity 2 (52), rocker piece (6), cylinder cap 2 (7), cylinder cap 3 (8) forms. The element of structure is all cylinder except cone bar (2), cone bar (2) is cone, it is connected with cylinder cap 1 (1) to be placed in inner chamber 1 (51) and form taper hole with the centre bore of cylinder cap 2 (7) and coordinates, clay elastomer is filled in inner chamber 1 (51), inner chamber 2 (52) fills noble gas or air, forms one by being spirally connected equipped with the cylinder cap 1 (1) of sealing device (4), cylinder cap 3 (8) and housing (5), cylinder body (3) and seals entirety.
Owing to have employed technique scheme, this utility model has the following advantages and effect:
1. this utility model is applicable to the safe buffering of big weight classes workpiece.
2. this utility model have employed the medium that clay elastomer is filled as inside, and clay elastomer is a kind of semifluid macromolecular material, has high viscosity, compressibility, special chemical inertness and good heat stability, the envelope size of load-displacement curves is big, and energy-absorbing effect is notable.
3. this utility model reasonable in design, volume is little, easy for installation, and without aging and leakage phenomenon, long service life, maintenance and repair are simple and easy.
Accompanying drawing explanation
Fig. 1 is the overall cross-sectional schematic of this utility model structure, is in non-duty.
Fig. 2 is utility model works process schematic, and namely duty when clashing into occurs.
In figure: 1, cylinder cap 1,2, cone bar, 3, cylinder body, 31, cross glue hole, 4, sealing device, 5, housing, 51, inner chamber 1,52, inner chamber 2,6, rocker piece, 7, cylinder cap 2,8, cylinder cap 3.
Detailed description of the invention
As shown in Figure 1, cone bar mutative damp antivibrator is mainly by the cylinder cap 1 (1) equipped with sealing device (4), cylinder cap 3 (8) and housing (5), cylinder body (3) is spirally connected and forms a sealing entirety, clay elastomer is filled in inner chamber 1 (51), inner chamber 2 (52) fills noble gas or air, clay elastomer can pass through glue hole (31) and enter inner chamber 2 (52), rocker piece (6) equipped with sealing device (4) is placed in inner chamber 2 (52) and clay elastomer and gas is separated, prevent clay elastomer from leaking equipped with sealing device (4) between housing (5) and cylinder body (3), cylinder body (3) can be moved to the left along housing (5) internal diameter. the element of structure is all cylinder except cone bar (2), and cone bar (2) is cone. cone bar (2) is connected with cylinder cap 1 (1) to be placed in inner chamber 1 (51) and form taper hole with the centre bore of cylinder cap 2 (7) and coordinates.
Housing (5) leaves installation site, installs back casing (5) and coupled cylinder cap 1 (1), screw rod (2) maintains static. As shown in Figure 2, it is subject to external force F when boring bar mutative damp antivibrator and being hit, the entirety that cylinder body (3) and cylinder cap 2 (7), cylinder cap 3 (8) form is moved to the left along housing (5) internal diameter, clay elastomer produces counter-force F ' by compression to offset external force F, cone bar (2) forms the taper hole place of cooperation with the centre bore of cylinder cap 2 (7) and produces damping force, movement along with cylinder body (3), space between cone bar (2) and the centre bore of cylinder cap 2 (7) is gradually reduced, damping force is gradually increased therewith, forms the effect of mutative damp buffering. Clay elastomer by compression passed through glue hole (31) and entered inner chamber 2 (52), and promoted rocker piece (6) to move right, the gas filled in compression inner chamber 2 (52). After external force F cancels, in inner chamber 2 (52), the gas push rocker piece (6) of compression is moved to the left, rocker piece (6) pushes away clay elastomer and flows back to inner chamber 1 (51), and the entirety that cylinder body (3) and cylinder cap 2 (7), cylinder cap 3 (8) form moves right until being returned to initial condition along housing (5) internal diameter.
According to different working condition requirements, the tapering of cone bar (2) and the big I in the space reserved from the centre bore of cylinder cap 2 (7) carry out different changes by designing so that cone bar mutative damp antivibrator is adapted to more more specifically field requirement.
