Abstract
The utility model discloses a kind of vibration damper with position-limiting action, comprise snubber block (2), snubber block (2) is installed between upper member (5) and mounting plate (6), is fixed by tightening nut (7) and construction bolt (8); Also comprise a stop collar (3); Described stop collar (3) embeds and is arranged in snubber block (2) mounting hole, and stop collar (3) thickness size is less than snubber block (2) thickness size.When upper member applies pressure to snubber block, snubber block is compressed, when snubber block thickness direction size compression is to limit position, namely stop collar will contact with mounting plate with upper member, snubber block can not by continuation compression, thus realize spacing to vibration damper thickness direction, can effectively prevent vibration damper from occurring there is relatively large deviation in the position of the excessive assembly caused of decrement.
Description
Technical field
The utility model relates to the damping device in a kind of engineering machinery, specifically a kind of vibration damper with position-limiting action.
Background technique
Vibration damper is the element for alleviating mechanical shock, existing vibration damper is gum goods mostly, when vibration damper upper mounting component weight is excessive or after ageing of rubber, there will be vibration damper decrement to increase, to be there is very large deviation in the position of vibration damper upper mounting component, affect the performance of assembly; In addition when vibration damper is by cross shear, vibration damper easily deforms and damping effect is died down, or finally causes defective shock absorber.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of vibration damper with position-limiting action, and relatively large deviation appears in the position of the excessive assembly caused of decrement to prevent vibration damper from occurring.
To achieve these goals, a kind of vibration damper with position-limiting action of the utility model, comprise snubber block, snubber block is installed between upper member and mounting plate, is fixed by tightening nut and construction bolt; Also comprise a stop collar; Described stop collar embeds and is arranged in snubber block mounting hole, and stop collar thickness size is less than snubber block thickness size.
When upper member applies pressure to snubber block, snubber block is compressed, when snubber block thickness direction size compression is to limit position, namely stop collar will contact with mounting plate with upper member, snubber block can not by continuation compression, thus realize spacing to vibration damper thickness direction, can effectively prevent vibration damper from occurring there is relatively large deviation in the position of the excessive assembly caused of decrement.
As a kind of preferred version of the present utility model, described snubber block is damping rubber block.
As further improvement of the utility model, the both sides up and down of described snubber block are separately installed with upper limit lid and lower limit lid.When upper member applies pressure to snubber block, snubber block is compressed, and when snubber block thickness direction size compression is to limit position, namely stop collar will contact with upper and lower limited cover, vibration damper by continuation compression, thus can not realize spacing to vibration damper thickness direction.
As further improvement of the utility model, the technical problem that the utility model will solve further is to provide a kind of vibration damper, effectively prevent vibration damper causes vibration damper to be out of shape the defective shock absorber problem finally caused by cross shear, for this reason, in further improved plan, an improvement is more entered as of the present utility model, described upper limit lid lower end surface is formed with groove, lower limit covers end face and is formed with groove, snubber block is between two grooves, can carry out spacing to the circumferential size of snubber block, effectively prevent vibration damper causes vibration damper to be out of shape the problem of the defective shock absorber finally caused by cross shear simultaneously.

Fig. 2 is the utility model scheme of installation;
In figure: 1, upper limit lid, 2, snubber block, 3, stop collar, 4, lower limit lid, 5, upper member, 6, mounting plate, 7, tightening nut, 8, construction bolt.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model has the vibration damper of position-limiting action, comprises snubber block 2, and snubber block 2 is installed between upper member 5 and mounting plate 6, is fixed by tightening nut 7 and construction bolt 8; Also comprise a stop collar 3; Described stop collar 3 embeds and is arranged in snubber block 2 mounting hole, and stop collar 3 thickness size is less than snubber block 2 thickness size.Wherein, snubber block 2 selects damping rubber block.
Shock absorbing process is, when upper member 5 pairs of snubber blocks 2 apply pressure, snubber block 2 is compressed, when snubber block 2 thickness direction size compression is to limit position, stop collar 3 will contact with mounting plate 6 with upper member 5, snubber block 2 by continuation compression, thus can not realize spacing to vibration damper thickness direction, and relatively large deviation appears in the position of the excessive assembly caused of decrement can effectively to prevent vibration damper from occurring.
Specifically as shown in Figure 1, in the utility model, the thickness of damping rubber block is L2, and the thickness of stop collar is L1; The maximum compressibility so of the present utility model with the vibration damper of position-limiting action is: L2-L1, and the minimum thickness of damping rubber block is of a size of L1.
As another embodiment, the both sides up and down of snubber block 2 are separately installed with upper limit lid 1 and lower limit lid 4.Snubber block is compressed, and when snubber block thickness direction size compression is to limit position, namely stop collar will contact with upper and lower limited cover 1,4, and vibration damper by continuation compression, thus can not realize spacing to vibration damper thickness direction.
On the basis of a upper scheme, upper limit lid 1 lower end surface is formed with groove, and lower limit lid 4 upper-end surface is formed with groove, and snubber block 2 is between two grooves.Can carry out spacing to the circumferential size of snubber block 2, effectively prevent vibration damper simultaneously and cause vibration damper to be out of shape the problem of the defective shock absorber finally caused by cross shear.
