Description
Technical field
The utility model relates to physics teaching device, is specifically related to the modified node method of Experiments of Machanics tensile strength testing device puller system.
Background technology
Mechanical stretch test refers to is bearing the test method measuring material behavior under axial tensile loads.The data utilizing tension test to obtain can determine elastic limit of materials, length growth rate, elastic modulus, proportional limit, area reduction amount, pulling strengrth, yield point, yield strength and other tensile property index.The tension test carried out from high temperature can obtain creep data.The step of metal tensile test can see ASTM E-8 standard.The method of plastic tensile test is see ASTM D-638 standard, D-2289 standard (high strain-rate) and D-882 standard (fine sheet).ASTM D-2343 standard defines the stretching test method being applicable to glass fibre; The stretching test method being applicable to cementing agent is defined in ASTM D-897 standard; The stretching test method of rubberite is defined in ASTM D-412 standard.
Chinese patent literature CN203941060U, disclose a kind of fibre reinforced composites cryomechanics tensile property test frock clamp, this machine is undertaken wearing pin by the through hole of upper and lower chuck and is connected with the transmission rod of testing machine, carries out the test of fibre reinforced composites cryomechanics tensile property.What this patent puller system adopted is the transmission rod of testing machine, and the pulling force of tension tester generally adopts hydraulic-driven or weights, there is bulky, the large shortcoming of weights weight, is not suitable for using in laboratory.
Utility model content
The utility model provides a kind of puller system of mechanical stretch tester, the puller system that the utility model solves existing stretching testing machine exist bulky, weights weight large, is not suitable for the problem used in laboratory.
For solving the problem, the utility model adopts following technical scheme: a kind of puller system of mechanical stretch tester, comprise a framework 1, respectively there is a slideway 7 vertically arranged framework about 1 inner side, and is fixed with a horizontally disposed fixed bar 4 on rear side of framework 1; A balance stem 3 is horizontally placed in framework 1, and balance stem about 3 is held and coordinated with two slideways 7 respectively; Clamper 2 is separately installed with in the centre position of the following centre position of framework 1 back timber and balance stem 3 top; The following centre position of balance stem 3 is fixed with a rubber rods 6 vertically arranged, lever 9 is arranged at below rubber rods 6, lever 9 is vertical with balance stem 3, rubber rods 6 lower end and lever 9 stage casing hinged, lever 9 rear end is hinged by lever fulcrum shaft 8 and fixed bar 4 centre position, and lever 9 front suspension has weights 5.
Below the utility model, clamper pulling force is by lever transmission, and lever is with the lever fulcrum shaft on fixed bar for the strong point, and the length of lever moving arm is the total length of lever, and the length of lever resistance arm is the length of rubber rods lower end pin joint to lever fulcrum shaft.Because lever length is far longer than resistance arm length, therefore utilize less weights namely can produce larger pulling force.The utility model has that volume is little, weights is lightweight, easy to operate advantage, compares to be adapted at laboratory and to use.

Symbol description in figure: framework 1, clamper 2, balance stem 3, fixed bar 4, weights 5, rubber rods 6, slideway 7, lever fulcrum shaft 8, lever 9.
Embodiment
By best embodiment, the utility model is described in detail below.
As Figure 1-3, a kind of puller system of mechanical stretch tester, framework 1 is made up of back timber, left and right sidewall and base.Slideway 7 cross section that framework about 1 inner side is arranged is T-shaped, and a balance stem 3 is horizontally placed in framework 1, and balance stem two ends have T-shaped structure to coordinate with slideway, and this structure makes tension equalizer, and measurement accuracy is high.Be fixed with a horizontally disposed fixed bar 4 on rear side of framework 1, be separately installed with clamper 2 in the centre position of the following centre position of framework 1 back timber and balance stem 3 top.The following centre position of balance stem 3 is fixed with a rubber rods 6 vertically arranged, and can produce the skew of trace in lever drawing process, and adopting rubber rods to transmit pulling force is to adapt to skew, and offseting the measuring error produced can eliminate by calculating or reduce.Rubber used can be harder rubber, greatly shifted to prevent.Lever 9 is arranged at below rubber rods 6, lever 9 is vertical with balance stem 3, rubber rods 6 lower end and lever 9 stage casing hinged, lever 9 rear end is hinged by lever fulcrum shaft 8 and fixed bar 4 centre position, lever 9 front suspension has weights 5, weights can adopt pellet type structure, and pallet upper end connects lever front end.Said apparatus is widely used in the mechanical property test of the nonmetallic materials such as rubber, plastics, electric wire, yarn fabric, fiber or cloth and tinsel, metal forming, sheet metal and metal bar.Also be applicable to the stretching of various finished product, stripping, tear test.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among protection domain of the present utility model.
