Description
Technical field
The present invention relates to a kind of extensometer more particularly to a kind of novel large deformation extensometers.
Background technique
Extensometer is a kind of instrument for measuring line deformation between component and other object two o'clocks, usually by sensor, amplification
Device and logger three parts composition.Extensometer when measuring the stretch value of elastic material, match by extensometer and electronic universal tester
Set uses, and through two knife edge type gripper of extensometer on elastomer, extensometer can be automatic while stretching for elastomer
Deformation values are recorded, tradition needs to mark gauge length line in elastomeric test specimens in measurement, and there are maximum probability personnel operations for the method
Error, measurement accuracy are low.
Summary of the invention
In view of the foregoing drawbacks, the purpose of the present invention is to provide a kind of structure is simple, without being delineated in elastomeric test specimens
Gauge length line, reduce the personnel to operate error, a kind of high novel large deformation extensometer of measurement accuracy.
Thus the technical scheme adopted by the invention is that:
Including bottom plate and top plate, support rod and polished rod are equipped between the bottom plate and top plate, be cased on the polished rod upper guide bush and
Lower guide sleeve, movable sleeve is connected to clamper on the upper guide bush, and movable sleeve is connected to lower gripper, the top plate on the lower guide sleeve
Upper end is equipped with idler wheel, and the idler wheel is equipped with traction rope, and described traction rope one end is connect with upper guide bush, the connection of the traction rope other end
There is a weight, the outer surface of the upper guide bush and lower guide sleeve is equipped with graduation mark.
As a further improvement of the above technical scheme, the end of the upper clamper and lower gripper is respectively equipped with locking
Screw.
As a further improvement of the above technical scheme, the outer diameter one of the outer diameter of the upper guide bush and lower guide sleeve
It causes.
As a further improvement of the above technical scheme, the lower end surface of the upper guide bush and the upper surface of lower guide sleeve keep flat
Row.
As a further improvement of the above technical scheme, the upper clamper and lower gripper are knife edge type clamper.
The invention has the advantages that
The configuration of the present invention is simple, by delineating gauge length line on upper guide bush and lower guide sleeve, so as to avoid in elastomeric test specimens
Gauge length line is delineated, reduces the error of personnel's operation, substantially increases measurement accuracy.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
1 it is bottom plate in figure, 2 be top plate, 3 be support rod, 4 be polished rod, 5 be upper guide bush, 6 be lower guide sleeve, 7 is upper clamping
Device, 8 be lower gripper, 9 be idler wheel, 10 be traction rope, 11 be weight, 12 be graduation mark, 13 be lock-screw.
Specific embodiment
A kind of novel large deformation extensometer, including bottom plate 1 and top plate 2 are equipped with support rod 3 between the bottom plate 1 and top plate 2
With polished rod 4, upper guide bush 5 and lower guide sleeve 6 are cased on the polished rod 4, movable sleeve is connected to clamper 7 on the upper guide bush 5, described
Movable sleeve is connected to lower gripper 8 on lower guide sleeve 6, and 2 upper end of top plate is equipped with idler wheel 9, and the idler wheel 9 is equipped with traction rope 10,
Described 10 one end of traction rope is connect with upper guide bush 5, and 10 other end of traction rope is connected with weight 11, the upper guide bush 5 and lower guide sleeve 6
Outer surface be equipped with graduation mark 12.
As a further improvement of the above technical scheme, the end of the upper clamper 7 and lower gripper 8 is respectively equipped with lock
Tight screw 13.
As a further improvement of the above technical scheme, the outer diameter of the outer diameter of the upper guide bush 5 and lower guide sleeve 6
Unanimously.
As a further improvement of the above technical scheme, the lower end surface of the upper guide bush 5 and the upper surface of lower guide sleeve 6 are kept
In parallel.
As a further improvement of the above technical scheme, the upper clamper 7 and lower gripper 8 are knife edge type clamping
Device.
It is emphasized that: the above description is only an embodiment of the present invention, is not intended to limit the scope of the invention,
It is all to utilize equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content, it is applied directly or indirectly in
Other related technical areas are included within the scope of the present invention.
