Embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.
As Fig. 1, Fig. 2, a kind of efficient testing machine of surveying pretightning force, it comprises base 1, U-shaped seat 2, radial digital display push-pull effort sensor 3, holder 4, riser 6, pre-tightening sleeve 8, pretension plate 9, push-botton operation case 10 and gantry operation panel 11, wherein,
Push-botton operation case 10 is connected with gantry operation panel 11, base 1 is fixed on the gantry operation panel 11, U-shaped seat 2 and holder 4 are fixed on the base 1, riser 6 is installed on the holder 4 by socket head cap screw 5, the spoke of radial digital display push-pull effort sensor 3 is installed on the U-shaped seat 2 by fixed pin 7, the digital display meter of radial digital display push-pull effort sensor 3 is installed on the riser 6, pre-tightening sleeve 8 is installed in the spoke endoporus of radial push-pull effort sensor 3, as Fig. 3, also and between the pre-tightening sleeve 8 there is gap 12 in the outside that pretension plate 9 is installed in U-shaped seat 2.
The riveted joint direction of described push-botton operation case 10 pre-tightening sleeves 8 and pretension plate 9 is provided with removal hole, so that when riveted joint is easy to loading and unloading.
