On guide card 9 and bottom right guide card 14, i.e., upper jaw seat 11 is alignd with lower jaw seat 12, then upper left extended panel seat 5 with spring 16
Caught on the extend spring shaft 15 of panel seat 8 of upper right, realize the fixation of upper jaw seat 11.
Upper jaw seat 11, lower jaw seat 12 are finally compressed into experiment jaw 1 again respectively.
During experiment, the probe of length gauge 4 contacts with adjusting bolt 7, because the probe of length gauge 4 can under applied external force
Stretch back and forth, when sample 2 produces the deformation of length direction in the presence of drag load, its deflection is led by upper guide card with
Piece be delivered to extend panel seat and under extend on panel seat, above extend panel seat and under panel seat of extending make relative disPlacement motion, amount of exercise
It is delivered to by the adjusting bolt 7 above extended on panel seat on length gauge 4, the probe of length gauge 4 produces change in displacement therewith, then leads to
Cross computer digital animation and obtain the warped digital amount of sample 2, realize the purpose of deformation measurement.
Because measurement apparatus component of synchronously extending is that a rigidity is overall, especially as the upper jaw of deformation value transmission
Seat 11 and lower jaw seat 12 can accurately reflect the deflection of sample in real time as single rigid element, make the length of both sides
Measurement value synchronously increases or decreases, and realizes the accurate measurement of sample deformation.Again because the knot being oriented to using steel ball and V-shaped groove
Structure, reduce influence of the frictional force to test data.Sample jaw 1 can be changed according to different size sample, pass through outfit
The sample jaw of plurality of specifications, can be achieved set of device measurement plurality of specifications sample function, overcome tradition extend measurement dress
The limitation of particular sample can only be done by putting set of device, reduce the use cost of user.Sample jaw 1 is simple in construction, reduces
Difficulty of processing, processing cost is saved, overcome the problem of experiment jaw difficulty of processing is big, and cost is high.
