Abstract
The invention discloses a multi-sample parallel experiment clamp for providing a continuous clamp force. The multi-sample parallel experiment clamp is used for clamping multiple parallel samples on a material tester and comprises an upper adapter positioning flange (1) and a lower adapter positioning flange (9) symmetrical with the upper adapter positioning flange (1). On each one of the flanges, Chinese character Mi-shaped positioning channels composed of three chutes going through the flange center are arranged, the two positioning channels forming a right angle are respectively provided with four positioning racks, the rest of the positioning channels is provided with a positioning rack going through the flange center, the positioning rack is connected to the positioning flange by bolts, the positioning rack has a U-shaped structure, and a pair of clamping blocks are arranged in each one of the positioning racks, wherein the opening and closing of the pair of clamping blocks are controlled by a specially-produced screw. The multi-sample parallel experiment clamp can be used for multiple parallel samples arranged on a material tester and has the advantages of high efficiency, continuous clamp force, sample sliding prevention, operation simpleness, economy and practicability.
Description
Technical field
The invention 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.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the object of the invention is to construct a kind of many samples parallel laboratory test fixture that lasting clamping force is provided, make it the above shortcoming overcoming prior art.
The object of the invention is by following means realize.
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 invention 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 invention assembling schematic diagram.
Fig. 2 is that the present invention transfers the vertical view of locating flange.
Fig. 3 is fixture block locating rack structural drawing of the present invention, wherein: (a) front elevation; (b) side view.
Fig. 4 is the structural drawing of fixture block of the present invention, wherein, and (a) front elevation, (b) vertical view.
Fig. 5 is the structural drawing of the special screw rod of the present invention.
Embodiment
Below in conjunction with accompanying drawing, structure of the present invention is described in further detail.
The present invention 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 present invention 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.
In the present invention, 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 present invention 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.
