Description
Technical field
The utility model belongs to the fixture association area of Material Testing Machine clamping sample.
Background technology
Material Testing Machine carries air-actuated jaw or hydraulically operated fixture usually.Above-mentioned fixture has centering good, the advantages such as holding force is adjustable.But for the situation needing to repeat to test to meet experimental standard requirement or meet scientific research statistics average demand, such fixture needs to carry out many experiments usually, and efficiency is lower.Usually pneumatic or hydraulically operated fixture volume is comparatively large, and needs to connect a lot of hydraulic oil pipe or pneumatic tube, not easily directly uses in sweat box, causes such fixture to carry out high temperature or low-temperature test has some limitations.
Mechanical clips generally can meet the requirement of experiment of high temperature or low temperature.All kinds of mechanical clips common at present, adopt the method for screw threads for fastening usually.Although such fixture is simple and easy to use, such fixture can not provide lasting clamping force.For some softer materials as macromolecular material, due to the viscoelastic property of material, after screw threads for fastening can there is creep behaviour in material.Can cause in experimentation like this and occur that specimen size attenuates, phenomenons such as loosening appears in clamping, sample can be caused time serious to depart from fixture, cause the failure of an experiment.And mechanical clips can only carry out single experiment usually, efficiency is lower.
For some softer materials, common testing machine load range is excessive, carries out the problem due to sensor resolution when individual sample is tested, easily produces experimental error.Once carry out the experiment of multiple sample, not only can improve the service efficiency of testing machine, and the experimental precision for softer material can be improved.
Utility model content
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is a kind of many samples parallel laboratory test fixture providing lasting clamping force of structure, makes it the above shortcoming overcoming prior art.
The purpose of this utility model is realized by following means.
Many samples parallel laboratory test fixture of lasting clamping force being provided, for realizing the parallel clamping of multiple sample in Material Testing Machine, there is upper switching locating flange 1 and lower switching locating flange 9 symmetrically arranged with upper switching locating flange about 1; On each flange, " rice " font placed channel formed by the chute in the flange center of circle by three, two placed channels at right angle each other split four block locating racks, and the placed channel of remainder is crossed the flange center of circle and arranges a locating rack, locating rack and locating flange adopt bolt-connection; Described locating rack takes the shape of the letter U structure, arranges a pair controls its folding fixture block by special screw rod in each locating rack.
Fixture of the present utility model can:
1, carry out the experiment (1≤n≤5) of n sample simultaneously;
2, lasting holding force is provided, prevents sample slippage in process of the test;
3, effectively can ensure fixture and sample centering while carrying out multiple specimen test, prevent eccentric moment;
4, be convenient for changing fixture block, carry out the material mechanical performance experiment of sizes sample;
5, the material mechanical performance experiment under multiple loading condition can be carried out.
Accompanying drawing is described as follows:
Fig. 1 is general structure of the present utility model assembling schematic diagram.
Fig. 2 is the vertical view of the utility model switching locating flange.
Fig. 3 is the utility model fixture block locating rack structural drawing, wherein: (a) front elevation; (b) side view.
Fig. 4 is the structural drawing of the utility model fixture block, wherein, and (a) front elevation, (b) vertical view.
Fig. 5 is the structural drawing of the special screw rod of the utility model.
Embodiment
Below in conjunction with accompanying drawing, structure of the present utility model is described in further detail.
The utility model can provide many samples parallel laboratory test fixture critical piece stainless steel of lasting clamping force to process, phenomenon of getting rusty under can effectively preventing wet environment.
Composition graphs 1-5 can see, the utility model can provide many samples parallel laboratory test fixture of lasting clamping force to have upper switching locating flange 1 and lower switching locating flange 9 symmetrically arranged with upper switching locating flange about 1; On each flange, " rice " font placed channel formed by the chute 11 in the flange center of circle by three; Two placed channels at right angle each other split four block locating racks, and the placed channel of remainder is crossed the flange center of circle and arranges a locating rack, locating rack and locating flange adopt bolt 8 to connect; Described locating rack takes the shape of the letter U structure, arranges a pair controls its folding fixture block 3 by special screw rod 4 in each locating rack.
As shown in Figure 5, A section and the C section of special screw rod 4 do not have screw thread, and interlude B comprises screw thread, and the design of this special screw rod can meet location, fastening, the object that provides lasting holding force in conjunction with spring simultaneously.
During use, first positioning cover plate 5 is fixed on fixture block locating rack 2 side by screw 7; Two Gent screw rods 4 are penetrated fixture block locating rack 2 by both sides pilot hole 13; The special screw rod 4 in left side penetrates spring 6 through fixture block locating rack 2 and enters fixture block 3 pilot hole 14, and the special screw rod 4 in right side enters fixture block 3 pilot hole 14 through fixture block locating rack 2.Empirically need to carry out 1 ~ 5 assembling (correspondence carries out the experiment of 1 ~ 5 sample).Fixture block 3 carries out coarse process with the surface of sample contacts, prevents sample slippage further.Locating rack to be fixed on switching locating flange 1 by placed channel 11 and pilot hole 12 bolt 8.By bolt 8, locating rack is fixed on switching locating flange.By locating flange 1 of transferring up and down) and (9) whole laboratory holder is connected in Material Testing Machine.
On the utility model, lower flange adopts identical structure, can carry out the material mechanical performance experiment of multiple sample after the sample that is installed.By changing fixture block 3, the material mechanical performance experiment of multiple specimen size can be carried out.One to five same size sample can be realized test simultaneously, and can ensure not produce eccentric moment.The advantages such as it is high that the utility model has efficiency, and structure is simple, multiple functional, easy to process, economic and practical, by being distributed to by uniform load on multiple sample, thus can improve experimental precision.
