Along crossbeam 1, move and load fastening sleeve 311, will load the correct position of support-moving to test specimen to be measured 7 tops.Then according to the position of load(ing) point, take crossbeam 1 as axle, rotate and load fastening sleeve 311, loading support is turned to proper angle.Then fastening loading fastening bolt 312, is fixed on loading fastening sleeve 311 on crossbeam 1.The loading coupling bolt 321 of take is again axle, and the extremely suitable angle of rotation loading support, makes to load the loading direction of support and the normal direction of load(ing) point overlaps.Keep loading backing positions constant, from loading coupling bolt 321 ends, be inserted in position limited gear 322, position limited gear 322 is supported and terminate on the boss 3211 that loads coupling bolt 321.Constantly finely tune position limited gear 322 simultaneously, make position limited gear 322 and fixed gear 313 engagements that load on fastening sleeve 311.Then be inserted in stop nut 323, position limited gear 322 is lock onto on boss 3211.
Unique sensor setting, in loading support top, and supports the probe 51 of displacement transducer 5 to terminate in mounting cylinder 34 tops, and can be with mounting cylinder 34 motions.
Rotate and load screw mandrel 339, power sensor 4 and pressure head 6 in mounting cylinder 34 are constantly declined, treat the load(ing) point imposed load of test block 7.With putting forth effort sensor 4 and pressure head 6, constantly decline, load continues to increase, and simultaneous displacement sensor 5 constantly obtains displacement data.
By power sensor 4 and displacement transducer 5, load can be obtained with the curve of change in displacement, anti-recessed rigidity property and the anti-recessed strength character of test specimen 7 to be measured can be obtained after treatment.
The testing apparatus of the charger providing based on the utility model can effectively complete dent resistance and can test, and test accurately.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
