Concrete, when using, on the first fixture block and the second fixture block, the open end of T-slot is provided opposite to, and so, is treating
The screw rod of experiment or nut, after threaded each self-corresponding nut and screw rod, can form an I-shape construction, this work
The wider part in character form structure two ends is arranged on the bottom of two T-slots respectively, at the first fixture block and/or the second fixture block with liquid
During pressure testing machine motion, tension can be applied on I-shape construction, reach the purpose of bolt rubbish experiment.Use this
Structure, is connected to hydraulic dynamometer compared to being directly connected to bolt, has and picks and places bolt on hydraulic dynamometer and be faster than tradition side
The efficiency that case is ten times.
Further technical scheme is:
The for the benefit of uniformity of each point stress, the axle of described first pull bar on the first pull bar, the first fixture block, screw rod or nut cross section
The centerline collineation of T-slot on line and the first fixture block.
The for the benefit of uniformity of each point stress, described second pull bar on the second pull bar, the second fixture block, screw rod or nut cross section
Axis and the second fixture block on the centerline collineation of T-slot.
In the case of there is no auxiliary threaded rod or nut, all it is not provided with for making this fixture can at least can be used for two ends
The threaded rod of screw cap end, one end are provided with the pull test of the screw rod of screw cap end, the T-slot on the first fixture block and/or the second card
Being provided with nut in T-slot on block, described nut is positioned at the bottom of corresponding T-slot.
The method have the advantages that
In this structure, on the first fixture block and the second fixture block, the open end of T-slot is provided opposite to, so, at screw rod to be tested
Or nut, after threaded each self-corresponding nut and screw rod, an I-shape construction can be formed, this I-shape construction two
Hold wider part to be arranged in respectively on the bottom of two T-slots, transport with hydraulic dynamometer at the first fixture block and/or the second fixture block
During Dong, tension can be applied on I-shape construction, reach the purpose of bolt rubbish experiment.Use this structure, compare
It is connected to hydraulic dynamometer in being directly connected to bolt, has and on hydraulic dynamometer, pick and place bolt be faster than the effect of traditional scheme ten times
Rate.
