Abstract
The invention provides a vibration absorber for a precise mechanical equipment, which comprises four groups of flexible units in cross layout. An upper plate and a lower plate are respectively connected with an upper contact surface and a lower contact surface of the four groups of flexible units to form an interlayer structure; the flexible unit comprises four pressure bearing blocks, a plurality of rubber blocks and two double bevel connecting blocks in X-shape layout. Therefore, due to simple structure, average and balanced stress for the symmetric structure of two layers, stable rigidity for the cross arrangement structure for the flexible unit, the invention has excellent vibration isolation effect in six directions.
Description
Technical field
The present invention relates to the mechanical shock absorption field, especially about a kind of accurate mechanical equipment vibration absorber.
Background technique
Accurate mechanical equipment has strict technical requirements for impact shock in the process of transportation, if impact shock has exceeded the ability to bear of equipment, can influence usability, even the precision of the equipment of destruction.
Existing vibration damper generally adopts the rubber material, as the stressed rubber absorbers in the described a kind of inclined-plane of Chinese utility model patent CN200520062240.0, its shock-absorbing main bodies is an individual layer yielding rubber piece, the damping scope is little, each is bigger to the damping property difference, the pressure-bearing direction is single, when being difficult to satisfy the precision equipment transportation on six direction the shock attenuation needs of high target.
Summary of the invention
For satisfying precision equipment respectively to high shock attenuation needs, the invention provides a kind of accurate mechanical equipment vibration absorber, comprise four groups of flexible unit, be cross arrangement; A upper plate and a lower plate are connected with the surface of contact up and down of four groups of flexible unit respectively, form sandwich structure.
Flexible unit comprises that four pressure blocks, plurality of rubber piece and two are with bibeveled contiguous block; Pressure block is connected with an inclined-plane of contiguous block by block rubber, and two contiguous blocks are symmetrical arranged up and down, totally form X type structure; Wherein two of contiguous block inclined-plane bilateral symmetry are identical with the angle of horizontal plane, between 30 degree～45 degree.
The present invention is simple in structure, the stressed uniform balance of two-layer symplex structure, and the cross arrangement structural rigidity of its flexible unit is stable, also has good horizontal to damping effect except that Vertical direction.

Embodiment
Below by Figure of description, elaborate a specific embodiment of the present invention:
In conjunction with Fig. 1 to Fig. 6, the present invention includes four groups of flexible unit 1 that are cross arrangement, upper plate 2 and lower plate 3, the cross arrangement structure is as shown in Figure 4.Flexible unit 1 is connected with upper plate 2 by the last plane of pressure block 11 and pressure block 12, and the lower plane by pressure block 14 and pressure block 15 is connected with lower plate 3.
Flexible unit 1 is by contiguous block 16,17, pressure block 11,12,14,15 and plurality of rubber piece 13 are formed, contiguous block 17 is connected with block rubber 13 by two inclined-planes on it, each inclined-plane connects 2～3 block rubbers 13 as required, block rubber 13 adopts corrosion-resistant, ageing-resistant rubber material, and its effect is to transmit next machinery load weight and shock absorbing vibration to bear upper plate 2.Two inclined-plane bilateral symmetry of contiguous block 17, and the angle of horizontal plane is 30 ° of (actual can being adjusted at according to demand between 30 °～45 °, have optimum efficiency), can reduce the shearing impact load of block rubber 13 relative ability to bear differences, thereby improve single block rubber bearing capacity.Pressure block 11 is connected with block rubber 13 by the inclined-plane on it respectively with pressure block 12, and the angle of its inclined-plane and horizontal plane is identical with the inclined-plane of contiguous block 17.In the same way, contiguous block 16 interconnects with pressure block 15,14 and block rubber 13.Contiguous block 17 is symmetrical arranged up and down by plane and contiguous block 16, totally forms an X type structure.This two-layer symplex structure, stressed uniform balance, because the flexible amount of block rubber increases, effectiveness in vibration suppression is remarkable.
Four groups of flexible unit 1 are cross arrangement, structural rigidity is stable, when the impact shock that is subjected to six direction, when particularly horizontal impact vibrates, all have at least the block rubber 13 of two groups of flexible unit 1 to bear and draw load or compressive load, therefore reduced the shearing load of block rubber 13 relative ability to bear differences, thereby improved the bearing capacity of whole vibration damper, effectiveness in vibration suppression is remarkable.
That more than introduces only is based on a preferred embodiment of the present invention, can not limit scope of the present invention with this.Any mechanism of the present invention is done replacement, the combination, discrete of parts well know in the art, and the invention process step is done well know in the art being equal to change or replace and all do not exceed exposure of the present invention and protection domain.
