Description
Technical field
The utility model relates to the aligning device structure of sheet coupon tension test, particularly about a kind of aligning device for the sheet coupon tension test in mechanics properties testing field.
Background technology
Tensile property is the basic mechanical performance of material, and the intensity of material, plasticity, the mechanical performance index such as strain hardening and toughness are referred to as tensile property.Other mechanical properties such as fatigue, fracture of the measurable material of tensile property.In engineer applied, tensile property is the Main Basis of structural static strength design.
Tension test is that standard tensile specimen is pulled to fracture with the rate of extension of regulation under static axial tensile force constantly acts on, and in drawing process continuous record power and elongation, thus obtain the mechanical property test of its Strength Criterion and plasticity criterion.
When carrying out tensile sample, owing to installing the factors such as incorrect, sample can be subject to the effect of eccentric force, because it can make sample produce additional bending stress, thus causes the deviation of test findings.Special in hard brittle material, because in drawing process, the distortion of sample is not enough to make the force line of stretching and the dead in line of sample, this deviation is more obvious.Special in sheet coupon, because of its stretching employing is dull and stereotyped chuck, because not having object of reference to be not easily arranged on the same vertical axis of upper lower chuck by sample during testing crew installation sample, thus causes measuring error.
Summary of the invention
In order to reduce the issuable measuring result error of this artificial installation, according to stretch test conditions and concerned countries examination criteria, the utility model is intended to design a set of aligning device being applicable to tension test without thickness sheet coupon.
The utility model is achieved through the following technical solutions:
A kind of aligning device for sheet coupon tension test, the utility model is made up of fixture block, T-slot, locating device and subsides chi, T-slot is separately positioned on upper and lower two pieces of fixture block corresponding surfaces, paste chi to be located at respectively in the T-slot of fixture block, paste chi to be free to slide in T-slot, the indication end of backstay is pointed to and is pasted chi, coordinate the locating device formed to point to by backstay with pilot pin upper and lower fixture block two and paste chi identical graduation, after fixing in location and adopting nut fixing, plate stretch sample holder end and upper and lower backstay being reclined realizes sample and aligns.
The utility model is processed by high strength alloy steel, and Chrome spray treatment is heat-treated and plated on surface, and fixture block 1A face is sample sandwich serface by the utility model, is processed as serrulate, to increase the friction force of sandwich serface.Two fixture block corresponding surfaces and C face open T-slot respectively, and T-slot bottom surface need be vertical parallel with C face with fixture block 1B face.Pasting chi is positioned on fixture block C face, consistent with T-slot direction of slotting.Backstay coordinates with pilot pin and forms locating device, make it can be free to slide in T-slot, backstay indication end is pointed to and is pasted chi, upper and lower fixture block two locating devices are pointed to and pastes chi identical graduation, after fixing by nut, plate stretch sample holder end and upper and lower backstay being reclined realizes sample and aligns.
The form of the upper and lower fixture block of the utility model is consistent.
The beneficial effects of the utility model are, this device can make sheet coupon be arranged on the same vertical axis of lower chuck, thus can reduce the man's activity of installing sample, reduce testing inspection resultant error, improve the reliability of testing result.
