Specific embodiment
Develop simultaneously embodiment below in conjunction with the accompanying drawings, describes the present invention.
As shown in figure 1, the invention provides a kind of three-dimensional stop, including limit shaft 2, base 5, helical steel springs 3, steel
The spring axis of guide 4 and two limit shaft counterparts 1；
As shown in Figure 2 a and 2 b, limit shaft counterpart 1 is a square block having ladder semi-circular recesses；
As shown in Figure 3 a and Figure 3 b shows, limit shaft 2 is stepped cylindrical, cylinder boss and the limit shaft that an interlude has boss
The groove of counterpart 1 is corresponding, and the spring contact jaw of limit shaft 2 is provided with positive stop lug boss；Limit shaft 2 is internal to be solid steel
Material, outer surface is vulcanised rubber layer.
It is spacing that limit shaft 2 realizes three-dimensional in the form of multidiameter with limit shaft counterpart 1, particularly circumferential any direction
All enable spacing.
As shown in figure 5 a and 5b, base 5 is a base plate being welded with two-layer cylindrical cavity, the top surface of two-layer cavity
It is provided with hole, the central axes of two cavitys；
As shown in figures 4 a and 4b, the steel spring axis of guide 4 is a cylinder；
Helical steel springs 3 have certain three-way rigidity, make limit shaft 2 realize buffering reset function；
Integrated connection relation：Base 5 is positioned on level table, and the steel spring axis of guide 4 is connected in the internal layer cavity of base 5
In, helical steel springs 3 are nested in and are slidably matched with the steel spring axis of guide 4 on the steel spring axis of guide 4, are easy to helical steel springs 3
Positioning is installed and position limitation protection is carried out to helical steel springs 3.Helical steel springs 3 one end and base 5 are connected, the other end and limit shaft
2 spring contact jaw is connected, and the positive stop lug boss of limit shaft 2 is embedded between internal layer cavity and outer layer cavity, by rotary stopper axle
2 so that positive stop lug boss is realized staggered spacing between two-layer cavity, and two limit shaft counterparts 1 are connected under equipment under-chassis
Surface, forms the annular chamber of certain interval with limit shaft 2 after two limit shaft counterpart 1 combinations.
Limit shaft counterpart 1 curvature radius of the contact with limit shaft 2 are identical, enable face contact, reduce impact process
In concentrated stress.
Adjusted between limit shaft 2 ± Z-direction by setting pad on the cylinder convex body and positive stop lug boss of limit shaft 2
Gap.On positive stop lug boss, adjust pad II7 is set, as shown in fig. 7, adjust pad II7 inserts the outer layer of base 5 at an angle
In cavity, after rotating to an angle, with the inner surface of outer layer cavity formed staggered spacing, adjust pad II7 be used for adjustable screw
The rigidity of steel spring 3 and the axial gap of limit shaft 2.The signal being adjust pad I6 and adjust pad III8 as Fig. 6 and Fig. 8
Figure, adjust pad I6 and adjust pad III8 are used for the axial gap of auxiliary adjustment limit shaft 2.
This three-dimensional stop is multidiameter form, can carry out ± X, ± Y to system, ± Z-direction is spacing.For avoiding secondary punching
Hit, this stop is designed to elastic spacing device, lower end is rigidly fixed with base 5 by the helical steel springs 3 with certain rigidity.?
When equipment vibrating isolation system is impacted by all directions, smaller when impacting, due between limit shaft counterpart 1 and limit shaft 2
There is certain primary clearance, do not collide, the dynamic respond that now equipment produces does not affect the normal fortune of whole vibrating isolation system
OK；Larger when impacting, vibrating isolation system and limit shaft counterpart 1 are up to certain dynamic respond, when dynamic respond reaches initially
Behind gap, limit shaft counterpart 1 and limit shaft 2 start to occur to act on the constant elastic collision of generation rigidity by helical steel springs 3,
Continue to increase with dynamic respond, for preventing helical steel springs 3 from occurring large deformation to damage, the internal layer cavity of base 5 plays
The effect of protection helical steel springs 3, limit shaft counterpart 1 produces, with limit shaft 2, the non-thread being caused by vulcanite and single solid steel
Property rigidity collision, consume impact shock energy after limit shaft 2 due to helical steel springs 3 effect automatically restore to original state.
Apparatus of the present invention have by helical steel springs 3 (linear rigidity) and single solid steel+vulcanite (non-linear rigidity) group
The two grades of elastic spacing functions of becoming.
In sum, these are only presently preferred embodiments of the present invention, be not intended to limit protection scope of the present invention.
All any modification, equivalent substitution and improvement within the spirit and principles in the present invention, made etc., should be included in the present invention's
Within protection domain.
