Description
Technical field
The utility model is related to a kind of test apparatus, and more particularly to a kind of high-strength bolt is turned round to draw and becomeShape meter.
Background technology
Detection bolt turns round the deformation size drawn, and conventional method is mainly to be carried out using electronic extensometerDirect measurement, this method mainly has 2 shortcomings: one is smaller measurement range, high intensity spiral shellThe specification of bolt is a lot, measures the less high-strength bolt of length because that cannot install extensometer, soExtensometer direct measurement cannot be used, and in the bolt of all kinds of specifications, the less bolt of lengthTend to take up majority; Two is that the data result error measured is larger, and extensometer measurement is usedBe one direction measurement, so the data result error measured is larger.
Utility model content
The utility model is in order to make up the defect of prior art, there is provided a kind of simple structure, sideJust the high-strength bolt for using is turned round and draws deformation gauge.
The utility model is achieved by the following technical solution:
A kind of high-strength bolt is turned round and draws deformation gauge, including deformation-sensor support frame, deformationSensor and rotation loading device, are equipped with deformation measurement push rod on the rotation loading device, becomeEquipped with rotation load sleeve on shape measurement push rod, rotation loading device both sides are equipped with deformation measurement branchBrace, deformation measurement support arm both sides are symmetrically equipped with deformation measurement stretching arm, and two deformation measurements drawBoom point is respectively provided with holddown spring, and deformation measurement pressure is housed between two deformation measurement stretching armsTight arm, deformation measurement clamping arm centre is top equipped with deformation measurement, the support of two deformation measurementsArm end is respectively provided with deformation-sensor, and two deformation-sensor ends are respectively provided with deformation-sensorSupport frame.
The beneficial effects of the utility model are: simple structure, easy to use, are easy to production to install,Reduces cost, overall structure was not only firm but also flexible, expanded measurement range, the number measuredIt is smaller according to resultant error.
