Description
Technical field
The utility model relates to a kind of measurement mechanism, particularly relates to a kind of Simple high-strength degree torque coefficient of bolt determinator.
Background technology
At present, high-strength bolt has general application in large-scale steel structure engineering and thin-walled box bridge.But the manufacture of high-strength bolt comparatively plain bolt wants complicated and strict, but also needs the detection means of a set of science, wherein most important is exactly the pick-up unit of torque coefficient.The assay method of torque coefficient has multiple, the test of current high-strength bolt torque coefficient generally all uses axle power meter or special sensor, and such proving installation often all costly, and operation more complicated, infrequently carry out the unit of high-strength bolt installation, general all do not have these specialized equipments costly, and this makes the mensuration of high-strength bolt torque coefficient seem and very inconvenience causes the puzzlement in design and construction to some unit.
Summary of the invention
The purpose of this utility model is just to provide a kind of Simple high-strength degree torque coefficient of bolt determinator to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises setting nut, digital display draw-bar donamometer, contiguous block, hold-down nut, casing, bolt to be measured, fastening nut, sleeve and torque spanner, the two ends car of described digital display draw-bar donamometer has external thread, the notch of certain depth is opened in the both sides of described casing and described contiguous block, described digital display draw-bar donamometer is connected with described casing and described contiguous block by notch with described bolt to be measured, described setting nut and described hold-down nut are arranged on left surface in the left end face of described casing and the chamber of described contiguous block respectively and are threaded connection and be connected with the two ends of described digital display draw-bar donamometer, described fastening nut is arranged on described casing its right end face and is threaded connection and is connected with described bolt to be measured, described jacket casing is on described fastening nut, described torque spanner is connected with described fastening nut by described sleeve.Described bolt to be measured is installed in determinator, described setting nut is regulated to make described digital display draw-bar donamometer reading be zero, described torque spanner is enclosed within described sleeve, apply certain moment, and read the reading that now described digital display draw-bar donamometer and described torque spanner show, the numerical value of described torque coefficient of bolt to be measured can be obtained by moment divided by the product of value of thrust and bolt diameter, so just reach the object measuring high-strength bolt torque coefficient.
The beneficial effects of the utility model are:
