Abstract
The utility model provides a stud shaft is to force transducer for measure bolt axial strain, include: bolt, strainometer, the bolt cap of bolt is equipped with a hole, and the diameter in hole is greater than the strainometer diameter, the strainometer is arranged in downtheholely. This stud shaft is to force transducer, simple structure fastens the linear relation who does all can with axial strain according to the axial that the bolt received, can conveniently calculate the axial fastening power that the bolt received.
Description
Technical field
The utility model relates to commercial vehicle component detection field, especially a kind of axial force sensing detection device.
Background technology
At commercial car design field, in order to optimal design, often need to detect the real load suffered by each parts, best detection method is exactly measure to axially fasten power suffered by coupling bolt.But the power that axially fastens of bolt cannot directly be measured, and first must measure axial strain, according to axial strain and the linear functional relation axially fastening power, obtain and axially fasten power.This product can be applicable in the structural member forces testing in the fields such as automobile, high ferro, aircraft.
Utility model content
The purpose of this utility model is, provides a kind of device measuring bolt axial strain.
Axial stress in bolt sensor described in the utility model, comprising: bolt, strainometer,
The bolt cap of bolt is provided with a hole, and the diameter in hole is greater than strainometer diameter;
Strainometer is placed in hole.
Preferably, described hole is arranged on Shuan Mao center.
Preferably, described hole is blind hole.
Preferably, described strainometer is fixed in hole.
Preferably, described strainometer is through sealing and is fixed in hole.
Preferably, described strainometer has wiring.
More preferably, described wiring is stretched out outside hole.
Preferably, what described strainometer adopted is embedded strain gauge.
When this Axial stress in bolt sensor uses, be first placed on testing machine and calculate demarcation file, the power that axially fastens namely suffered by bolt and the relation of axial strain, determine linear functional relation; Treating on geodesic structure by Axial stress in bolt sensor bolt again, to treating that geodesic structure adds load, strainometer passes out strain data by wiring; Finally axially fasten power according to what demarcate that axial strain to be converted into that bolt is subject to by file.
Axial stress in bolt sensor described in the utility model, structure is simple, the power that axially fastens suffered by bolt and the linear relationship of axial strain, and what conveniently can calculate that bolt is subject to axially fastens power.

When this Axial stress in bolt sensor uses, be first placed on testing machine and calculate demarcation file, the power that axially fastens namely suffered by bolt and the relation of axial strain, determine linear functional relation; Treating on geodesic structure by Axial stress in bolt sensor bolt again, to treating that geodesic structure adds load, strainometer passes out strain data by wiring; Finally axially fasten power according to what demarcate that axial strain to be converted into that bolt is subject to by file.
What strainometer 2 adopted is embedded strain gauge.
During use, be first placed on by Axial stress in bolt sensor on testing machine and calculate demarcation file, the power that axially fastens namely suffered by bolt and the relation of axial strain, determine linear functional relation;
Axial stress in bolt sensor bolt is being treated on geodesic structure, after adding load, is gathering strain data by strainometer wiring;
Finally according to demarcation file, strain is converted into bolt shaft to fastening force.
Axial stress in bolt sensor described in the utility model, structure is simple, easy to use.
