Abstract
A kind of anti-slip cramping apparatus suitable for thin plate tensioning member is the utility model is related to, plays the role of fastening mainly for thin plate, the soft tensioning member of matter and anti-skidding, including the anti-skidding pit of taper (2), anti-skidding sawtooth (1).When carrying out thin plate tension test on universal testing machine, anti-slip cramping apparatus is placed on to the inside of universal test machine clamp, the fixture of the anti-skidding pit of taper (2) universal testing machine of anti-slip cramping apparatus coordinates, the sawtooth (1) of anti-slip cramping apparatus is engaged with thin plate tensioning member, the retained part of thin plate tensioning member (3) is tightly pressed against inside fixture by the pressure and anti-slip cramping apparatus sawtooth (1) of universal test machine clamp, and makes the retained part deformation of thin plate tensioning member wavy in matching with anti-slip cramping apparatus.The point of fixture and tensioning member and the frictional force of point are converted into the face of anti-slip cramping apparatus and the frictional force in face when universal testing machine is stretched, while avoid the problem of soft thin plate tensioning member of matter is pulled out cut by universal test machine clamp taper anti-skid bulge.
Description
Technical field
It the utility model is related to and a kind of play the role of fastening and anti-skidding fixture for light sheet material tensioning member.
Background technology
With the continuous development of modern industry, either in school or enterprise, it is required for carrying out substantial amounts of metal material
Experiment, so that it is determined that the properties of material.Wherein the tension test of metal is for determining the elastic limit of metal material, extending
Rate, elasticity modulus, proportional limit, area reduction amount, tensile strength, yield point, yield strength and other tensile property indexs account for
There is highly important effect.Universal tensile testing machine carries out fastening anti-slip, universal tensile testing machine by its fixture to tensioning member
Fixture elastic force is delivered on the clamping plate of fixture by the elastic force of spring, and have on the clamping plate of the fixture of universal testing machine close
The tapered protrusion of cloth plays tensile test specimen anti-skidding effect.But cannot all it be risen for some very thin metal stretching test specimens
To the effect of fastening anti-slip, so slipping phenomenon is still very common in metal tensile test.For following several situations, metal
Slipping phenomenon during tension test is relatively common.
1. the softer metal material of quality.In tension test when drawing force is larger, in universal testing machine upper fixture
Taper anti-skid bulge can pull out cut in softer metal surface, so as to cause universal tensile testing machine fixture and tensile test specimen
It is opposite to slide, so as to cause the inaccuracy of measurement data.
2. relatively thin tensile test specimen.Universal test machine clamp be by spring elastic force be clamped due to, so
When tensioning member than it is relatively thin when, the clamping plate of universal testing machine is in minimum gap state, i.e. spring is in maximum length, minimum
Elastic force state.So it is in the state of the grip force minimum of fixture at this time naturally.So thin plate tensile test specimen is very easy to out
The phenomenon now skidded.
Utility model content
The utility model possesses the anti-skidding design in two sides, it is ensured that the firm installation with universal test machine clamp, and can
With ensure and thin plate, the soft class tensioning member of matter antiskid effect.
The utility model is carried out by following technical solutions.
1. a kind of anti-skid device suitable for thin plate tensioning member, including the anti-skidding pit of back side taper (1) (are tried with universal tensile
Test machine stretching clamp cooperation), the anti-skidding sawtooth of faying face (2) (being engaged with thin plate tensioning member), thin plate tensioning member (3).Anti-skidding cone
Shape pit diameter is 3mm, depth 1mm, its spacing of arranging is transverse direction 4mm, longitudinal 4mm.The cross sectional shape of anti-skidding sawtooth is three
It is angular.Its size is：Bottom side length 5mm, high 4mm.When carrying out thin plate tension test on universal testing machine, anti-slip cramping apparatus is placed on
The inside of universal test machine clamp, the fixture of the anti-skidding pit of taper (1) universal testing machine of anti-slip cramping apparatus coordinate, anti-slip cramping apparatus
Sawtooth (2) is engaged with thin plate tensioning member, is stretched thin plate by the pressure and anti-slip cramping apparatus sawtooth (2) of universal test machine clamp
The retained part of part is tightly pressed against inside fixture, and it is in match with anti-slip cramping apparatus to deform the retained part of thin plate tensioning member
It is wavy.When universal testing machine is stretched the frictional force of the point of fixture and tensioning member and point be converted into the face of anti-slip cramping apparatus with
The frictional force in face, while avoid universal test machine clamp taper anti-skid bulge and the soft thin plate tensioning member of matter is pulled out into asking for cut
Topic.
Brief description of the drawings
Fig. 1 is used cooperatively schematic diagram for anti-slip cramping apparatus with universal tensile testing machine fixture；
Fig. 2 is tensioning member and anti-slip cramping apparatus cooperation schematic diagram；
Fig. 3 is fitted close schematic diagram for tensioning member and anti-slip cramping apparatus；
Fig. 4 is anti-slip cramping apparatus schematic diagram.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
The basic thought of the utility model is put between the soft tensioning member of universal tensile testing machine fixture and thin plate, matter
Enter anti-slip cramping apparatus, to have the function that to ensure that thin plate tensioning member will not skid in drawing process.
When carrying out thin plate tension test on universal testing machine, anti-slip cramping apparatus is placed on to the inside of universal test machine clamp,
The fixture of the anti-skidding pit of taper (1) universal testing machine of anti-slip cramping apparatus coordinates, sawtooth (2) and the thin plate tensioning member phase of anti-slip cramping apparatus
Coordinate, be tightly pressed against the retained part of thin plate tensioning member by the pressure and anti-slip cramping apparatus sawtooth (2) of universal test machine clamp
Inside fixture, and make the retained part deformation of thin plate tensioning member wavy in matching with anti-slip cramping apparatus.By universal test
The point of fixture and tensioning member is converted into the face of anti-slip cramping apparatus and the frictional force in face with the frictional force put when machine stretches, and avoids at the same time
The problem of soft thin plate tensioning member of matter is pulled out cut by universal test machine clamp taper anti-skid bulge.
Claims (3)
