Abstract
The invention discloses a bolt tension test fixture. The bolt tension test fixture comprises a first clamping block and a second clamping block. A first pulling rod and a second pulling rod are fixedly connected to the first clamping block and the second clamping block respectively. The first pulling rod is used for fixed connection between the first clamping block and a hydraulic tester, and the second pulling rod is used for fixed connection between the second clamping block and the hydraulic tester. A T-shaped groove is formed in each of the first clamping block and the second clamping block. The bottom ends of the T-shaped grooves are wider than the open ends. The depth direction of the T-shaped groove in the first clamping block is parallel to the axis direction of the first pulling rod. The depth direction of the T-shaped groove in the second clamping block is parallel to the axis direction of the second pulling rod. The efficiency of picking and putting bolts on the hydraulic tester is improved by ten times when connecting the bolts to the hydraulic tester directly in the prior art is replaced by utilizing the bolt tension test fixture.

Bolt is a kind of mechanical component, is generally the cylindrical threaded securing member of adapted nut.Bolt is made up of head and screw rod (with externally threaded right cylinder) two parts, and need and nut screw connection during use, for being fastenedly connected two parts with through hole, this type of attachment claims bolt to connect.As nut is screwed off from bolt, can make again these two parts separately, therefore bolt connection belongs to removably connect.Divide by the force way connected: point common and have articulation hole.Divide by nose shape: have hexagon head, round end, square spigot, countersunk head etc.Wherein hexagon head is the most frequently used.At present, the bolt applying to different field or purposes emerges in an endless stream, and such as requires skin hardness high and heart portion has flexible self-tapping screw, for preventing the anticorrosive bolt, high temperature bolt etc. of flow-induced corrosion.But the basic purposes of bolt is the fastening needs being required to meet web member, therefore bolt has, and to meet the tensile strength used be basic demand to bolt.
In prior art in the process of bolt, need to carry out multi-step process, these manufacturing procedures generally comprise the treatment process for improving bolt mechanical property such as thermal treatment, surface carburization process.For the tensile mechanical Performance Detection of finished product bolt, in prior art, the general hydraulic dynamometer that adopts measures, but in prior art, the joint efficiency of bolt and hydraulic dynamometer is not high, affects the efficiency of bolt tension force test.
Summary of the invention
For the tensile mechanical Performance Detection for finished product bolt in above-mentioned prior art, in prior art, the general hydraulic dynamometer that adopts measures, but, in prior art, the joint efficiency of bolt and hydraulic dynamometer is not high, affect the problem of the efficiency of bolt tension force test, the invention provides a kind of bolt tension force test fixture.
A kind of bolt tension force test fixture provided by the invention solves problem by following technical essential: a kind of bolt tension force test fixture, comprise the first fixture block and the second fixture block, described first fixture block and the second fixture block are fixedly connected with the first pull bar and the second pull bar respectively, described first pull bar is used for being fixedly connected with of the first fixture block and hydraulic dynamometer, and described second pull bar is fixedly connected with for the second fixture block and hydraulic dynamometer;
Described first fixture block and the second fixture block are provided with a T-slot, the bottom width of described T-slot is greater than open end width, on first fixture block, the depth direction of T-slot is parallel with the axis direction of the first pull bar, and on the second fixture block, the depth direction of T-slot is parallel with the axis direction of the second pull bar.
Concrete, when using, on first fixture block and the second fixture block, the open end opposite of T-slot is arranged, like this, at screw rod to be tested or nut, be threaded after upper each self-corresponding nut and screw rod, can form an I-shape construction, the wider part in these I-shape construction two ends is arranged on the bottom of two T-slots, respectively in the process that the first fixture block and/or the second fixture block move with hydraulic dynamometer, tension can be applied on I-shape construction, reach the object of bolt rubbish experiment.Adopt this structure, be connected to hydraulic dynamometer compared to direct coupling bolt, have and pick and place the efficiency of bolt faster than traditional scheme ten times on hydraulic dynamometer.
Further technical scheme is:
The homogeneity that for the benefit of on the first pull bar, the first fixture block, screw rod or nut cross section, each point is stressed, the centerline collineation of T-slot on the axis of described first pull bar and the first fixture block.
The homogeneity that for the benefit of on the second pull bar, the second fixture block, screw rod or nut cross section, each point is stressed, the centerline collineation of T-slot on the axis of described second pull bar and the second fixture block.
When there is no auxiliary threaded rod or nut, the tensile test that two ends are not all provided with the threaded rod of screw cap end, one end is provided with the screw rod of screw cap end at least can be can be used for for making this fixture, be provided with nut in T-slot on T-slot on first fixture block and/or the second fixture block, described nut is positioned at the bottom of corresponding T-slot.
The present invention has following beneficial effect:
In this structure, on first fixture block and the second fixture block, the open end opposite of T-slot is arranged, like this, at screw rod to be tested or nut, be threaded after upper each self-corresponding nut and screw rod, an I-shape construction can be formed, the wider part in these I-shape construction two ends is arranged on the bottom of two T-slots respectively, in the process that the first fixture block and/or the second fixture block move with hydraulic dynamometer, tension can be applied on I-shape construction, reach the object of bolt rubbish experiment.Adopt this structure, be connected to hydraulic dynamometer compared to direct coupling bolt, have and pick and place the efficiency of bolt faster than traditional scheme ten times on hydraulic dynamometer.
