Description
Technical field
The utility model belongs to centering return technical field, is to be related to a kind of elastic reset structure more specifically.
Background technique
Component durings machine-building, processing, installation equipment, mold production, transferred product etc., in equipment
(contraposition component) generally requires to be aligned with another component (positioning element).When contraposition, contraposition component not only will receive with
Align contrary impact force, and position when due to contraposition between contraposition component and positioning element, angle there may be
Deviation, in this way in contraposition, contraposition component also suffers from extruding force that is vertical or favouring contraposition direction；Due to being set in difference
The direction that standby or different working hour contraposition component may be biased to positioning element is different from angle, i.e. contraposition component deviates just
The direction of beginning position can not determine that then the specific direction of the extruding force can not determine completely.In order to buffer impact when contraposition
Power generally requires and resetting structure is arranged between equipment and contraposition component, can push contraposition member reset by resetting structure.
However in some equipment, due to installation or need of work, resetting structure and the position that compresses of contraposition component are often not
Can with contraposition component fix, i.e., resetting structure with align component compress position generally require it is separately positioned.It aligns component and determines
When the component contraposition of position, contraposition component may be relative to its original position run-off the straight, offset or rotation；And it generally adopts in the prior art
Use if telescopic spring structure, cylinder and hydraulic cylinder structure are as resetting structure, these resetting structures can only single direction reset, i.e.,
It can only linearly be resetted, when aligning in this way, the position that resetting structure is compressed with contraposition component may then shift, and align
Initial position can not be pushed to by component is aligned according to the position that compresses after offset at rear resetting structure, that is, it is multiple to cannot achieve centering
Position.

Embodiment one:
Also referring to Fig. 1 to Fig. 3, now elastic reset structure 20 provided by the utility model is illustrated.The bullet
Property resetting structure 20, including guide post 25 and elastic telescopic part 21, guide post 25 offers guiding groove 251.Elastic telescopic part
21 one end is protruded into guiding groove 251, and one end of elastic telescopic part 21 supports the bottom of guiding groove 251, elastic telescopic part
21 telescopic direction is vertical with guiding 251 cross-sectional direction of groove, i.e., the telescopic direction of elastic telescopic part 21 is along guiding groove 251
Depth direction.And be oriented to groove 251 by its bottom towards the direction of its oral area in flaring shape, and be oriented to the interior of groove 251
Side 252 is in pass through elastic telescopic for guiding one end of elastic telescopic part 21 to slide to the curved of 251 bottom of guiding groove
The setting of part 21, may be implemented elastic telescopic function.Elastic telescopic part 21 is used for far from one end of guide post 25 and positioning element
(not shown) is fixed, and elastic telescopic part 21 is fixed on the position on positioning element with contraposition component face, corresponding guide post 25
One end far from elastic telescopic part 21 is used to fix with contraposition component (not shown).The structure of positioning element and contraposition component can be with
It makes identical, difference can also be made.In addition, when in use, can will be needed in equipment according to installation needs, need of work
Two components of contraposition are respectively defined as positioning element and contraposition component, it can by one in two components for needing to align
As positioning element, another is as contraposition component；It can certainly be by a conduct pair in two components for needing align
Position component, another is as positioning element.That is, when in use, which can be reversed use, that is, allow
Guide post 25 is connect far from one end of elastic telescopic part 21 with positioning element, and corresponding elastic telescopic part 21 is far from guide post 25
One end is connect with contraposition component.It is mounted on contraposition component using guide post 25 as example explanation below.
