Abstract
The invention discloses a tension and compression integrated clamp for a mechanical creep testing machine. The tension and compression integrated clamp comprises an upper tension chuck, an adjusting ball head, a lower compression chuck, an upper compression chuck and a lower tension chuck; the upper tension chuck and the lower tension chuck are dumbbell type test piece tension chucks, slots are formed in two sides of the tension chucks, a boss for bearing the lower compression chuck is outward arranged at the part, close to the opening of the tension chuck, at the slot of the upper tension chuck, a boss for bearing the upper compression chuck is outward arranged at the part, close to the opening of the tension chuck, at the slot of the lower tension chuck, two ends of the lower compression chuck and the upper compression chuck are matched with the bosses in shape, the middle part is a working surface, the working surface of the lower compression chuck has an inward depressed spherical structure, one side of the adjusting ball head is matched with the spherical structure of the lower compression chuck, and the other side is a plane. The tension creep test and compression creep test can be realized on the mechanical creep testing machine.
Description
Technical field
The invention belongs to mechanics of materials studying technological domain, particularly a kind of mechanical type creep testing machine pulling and pressing integratedization fixture.
Background technology
Creep test is one of important method of reflection solid material Viscous Elastic Mechanics, and mechanical type creep test device utilizes the gravity of counterweight as creep test loaded load, thus realize the permanent load required by creep test.Although mechanical type creep test device technology is full-fledged, its creep loading scope is subject to the restriction of the action direction of power, can only carry out tensile test.In the Viscous Elastic Mechanics research of solid material, a lot of material is had to need to carry out compression creep test because of the requirement of himself reasons in structure or mechanical property, the test that document " A thermo-viscoelastic-viscoplastic-viscodamage constitutive model for asphaltic materials " Asphalt Mixture carries out is exactly compression creep test, this just requires to complete compression creep test on existing mechanical type tensile creep endurance testing machine, so just need a kind of integrated clamp that can realize tensile creep and compression creep.
Summary of the invention
The object of the present invention is to provide a kind of mechanical type creep testing machine pulling and pressing integratedization fixture that can realize tensile test and compression creep test on mechanical type creep and stress rupture test machine.
The technical solution realizing the object of the invention is:
A kind of mechanical type creep testing machine pulling and pressing integratedization fixture, comprises tensioning chuck, adjustment bulb, lower compressed chuck, upper compressed chuck and lower tensioning chuck, upper tensioning chuck and lower tensioning chuck are dumbbell shaped test specimen tensioning chuck, the both sides fluting of tensioning chuck, the close tensioning chuck opening part of upper tensioning chuck fluting is to the boss being outside equipped with the lower compressed chuck of carrying, the close tensioning chuck opening part of lower tensioning chuck fluting is to the boss being outside equipped with the upper compressed chuck of carrying, lower compressed chuck and upper compressed chuck two ends shape coordinate with boss, middle part is workplace, the workplace of lower compressed chuck there is the spherical structure caved inward, the one side of adjustment bulb matches with the spherical structure on lower compressed chuck, another side is plane.
The present invention compared with prior art, its remarkable advantage:
(1) the present invention can realize the requirement completing compression creep on mechanical type tensile test machine, easy to use, economical and practical.
(2) the present invention does not adopt complicated structure to realize testing requirements, but is combined dexterously to meet testing requirements by the part of stretching clamp and compression clamp, and structure is simple.
