Description
Technical field
The utility model belongs to materials mechanics experimental device field, can realize the high-strength large hexagon head bolt used for steel structure pair, specifically comprise: the test of the torque coefficient of big hexagon head bolt, big hex-head nut, packing ring.
Background technology
When doing the torque coefficient testing experiment of big hexagon head bolt, big hex-head nut, packing ring, with reference to GB/T1228-1231-91 high-strength large hexagon head bolt used for steel structure, heavy series hexagon nut, packing ring and technical conditions, drive torque spanner by manpower and apply moment of torsion for the high-strength bolt pair, record torque value at that time when reaching axial assurance load, the manual calculations torque coefficient, moment when requiring the speed of record moment of torsion to be the manpower loading because of it, so the discreteness to same batch measurement result is very big, dynamometry is inaccurate.
Summary of the invention
The utility model provides a kind of bolt torsion testing machine, is that the discreteness to same batch measurement result that exists when applying moment of torsion of high-strength bolt pair is very big to solve with manpower drive square spanner, the inaccurate problem of dynamometry.The technical scheme that the utility model is taked is: pretension sensor and unit clamp are fixedlyed connected with support, torque and speed sensors is fixedlyed connected with support, measurement and display device are fixedlyed connected with support, servomotor and reductor are fixedlyed connected with the support bottom, the structure of pretension sensor and unit clamp is: the sleeve anchor clamps of hexangle type are fixedlyed connected with keyway with the anti-rotation support arm, the anti-rotation support arm is fixedlyed connected with sensor support base, sensor support base is fixedlyed connected with straight-line rolling guide set, the pretension sensor is fixedlyed connected with sensor support base, and force-bearing base is connected with sensor support base.
Adopt servomotor and reductor to do the loading system that applies moment of torsion, apply moment of torsion, form the bolt pretension measuring system, measure the bolt pretension value by pressure transducer and test fixture by the torque and speed sensors measurement.By singlechip computer system collection and control test speed and data acquisition, system carries out man-machine conversation by the soft machine of computing machine, calculates test findings at last.
Advantage of the present utility model is: novel structure, measure accurate, intelligent degree height, both can measure the torque coefficient of bolt pair, the guarantor who also satisfies the bolt pair is simultaneously carried test.
