According to the applicant understood, the prior art is put to the test the limitation of equipment and apparatus structure, only carries out a direction load
Test, three directions need to test respectively, therefore test efficiency is low, and are unable to get the test knot in three directions of synchronization
Fruit data.
Summary of the invention
It is an object of the invention to: in view of the problems of the existing technology, provide a kind of rubber nodal point three directional loads test
Device to significantly improve test operation efficiency, and obtains while the test data under compound stress.
Realize the object of the invention basic technical scheme be: a kind of rubber nodal point three directional loads experimental rig, comprising pedestal,
Adapter and twist mechanism；The pedestal contains the lower saddle and upper saddle that pairing grips rubber nodal point becket；Institute
It states adapter and extends the pinboard for being respectively positioned in rubber nodal point metal core axle both ends downward, the adapter extends upward
Link block, the top of the link block is fixed for applying the attachment base of radial load and side is fixed for applying deflection load
Connecting rod；The twist mechanism include inner end be circumferentially constrained in rubber nodal point metal core axle both ends respectively and outer end respectively and even
The left and right lever of spindle both ends connection, equipped with the connecting rod for applying torsional load in the connecting shaft.
Further, the upper surface of the attachment base is as radial load force surface.
Further, the outer end of the connecting rod is equipped with horizontal deflection load force surface.
Further, the upper end of the connecting rod is equipped with horizontal torsional load force surface.
Further, the radial load force surface, deflection load force surface and torsional load force surface pass through biography respectively
The power head of motivation structure and same load power-equipment is sequentially connected.
Further, the lower saddle that top has semicircle notch is fixed on the pedestal.
Further, upper saddle of the installation with opposed semicircular notch on the lower saddle.
Further, the top of the link block is protruded into fixed in the bottom surface slot of attachment base.
After applying the present invention, after torsion, radial direction, the terminal for deflecting biasing member being connected with corresponding power head respectively,
When the power head of twist mechanism small end applies vertical reciprocating motion active force, power is transmitted to by connecting rod by connecting shaft
Left and right lever, then so that metal core axle is generated twist motion trend by left and right lever, to apply torsional load.When with attachment base
When connected power head applies vertical reciprocating motion active force, adapter will be transmitted to by attachment base, and then be transmitted to rubber
The metal core axle of node makes it generate radial Tensile or Compressive Loading to rubber；When the power head application being connected with connecting rod outer end is vertical
When moving back and forth active force, rubber nodal point will be made to generate the trend rotated along horizontal radial axis (c-c), is carried to apply deflection
Lotus.
It can be seen that the present invention may be implemented simultaneously to carry out the torsional load of rubber nodal point, radial load, deflection load
Test, and since each load is by the power head generation of vertical reciprocating motion, device configuration is simple, and it is easy to operate, especially
It is can to enormously simplify research technique if necessary only with the power head of component output.

Fig. 2 is the side view of Fig. 1.
Fig. 3 is the schematic perspective view of one embodiment of the invention.
Fig. 4 is the twist mechanism schematic perspective view of Fig. 3 embodiment.
Fig. 5 is that the radial load of Fig. 3 embodiment applies the schematic perspective view of associated part.
Specific embodiment
The rubber nodal point three directional loads experimental rig of the present embodiment as shown in Fig. 3,4,5, comprising pedestal B, adapter T and
Twist mechanism.
The lower saddle 4-2-2 that top has semicircle notch is fixed on pedestal B, installation has opposite on lower saddle 4-2-2
Semicircle notch, the upper saddle 4-2-1 that rubber nodal point becket is gripped to pairing.
Adapter T is fixed to extend the vertical pinboard 4-1 for being respectively positioned in rubber nodal point metal core axle both ends, switching downward
The section of plate 4-1 is T-shaped, therefore stabilized structure, power transmission are reliable.
Top surface is protruded into for applying diameter in the fixed link block 2-9 extended upward on adapter T, the top of link block 2-9
It is fixed into the bottom surface 2-1-2 slot of the attachment base 2-1 of load, and side is fixed for applying the connecting rod 3-1 of deflection load,
The upper surface of attachment base 2-1 is radial load force surface, when applying vertical load to attachment base, will be transmitted to rubber nodal point
Mounting base, and then be transmitted on rubber nodal point, realize the application of radial load.The outer end of connecting rod 3-1 is equipped with horizontal deflection
Load force surface, when applying vertical active force to connecting rod outer end, it can be achieved that the deflection load of rubber nodal point loads.
Twist mechanism include inner end be circumferentially constrained in rubber nodal point metal core axle both ends respectively and outer end respectively with connecting shaft
Left and right lever 1-4,1-3 of the both ends 1-5 connection, therefore right lever, lever left reverse together with the metal core axle of rubber nodal point.
By bearing 1-2 equipped with the vertical connecting rod 1-1 for applying torsional load on connecting shaft 1-5, the upper end of connecting rod 1-1 is equipped with horizontal
Torsional load force surface.When connecting rod is by vertical active force, the flexible rotating of bearing can avoid connecting rod move up and down by
It hinders, so that the vertical active force of connecting rod is transmitted to left and right lever by connecting shaft, the mandrel of rubber nodal point is driven to generate torsion
Transhipment is dynamic.
By the radial load force surface of the upper surface attachment base 2-1 in this present embodiment, the deflection load of the outer end connecting rod 3-1
Force surface and the torsional load force surface of the upper end connecting rod 1-1 are vertical force surface, therefore can pass through transmission mechanism respectively
It is sequentially connected with the power head of same load power-equipment.In this way, not only may be implemented simultaneously to the torsional load of rubber nodal point,
Radial load, deflection load are tested, and since each load is generated by same power head, and test synchronism reaches
Perfect condition can obtain the exact test result data in three directions of synchronization, and equipment is simple, easy to operate.
In addition to the implementation, the present invention can also have other embodiments.It is all to use equivalent substitution or equivalent transformation shape
At technical solution, be all fallen within the protection domain of application claims.
