The utility model can meet intensity lower than 1000MPa, thickness is less than the solder joint cross stretching experiment requirement of the different trade mark Automobile Plate of 3mm, and guaranteed that experimentation sample is in four load(ing) points and two homogeneitys that are subject on force direction, guaranteed the accurate of experimental result, simultaneously this sleeve clamp volume small volume and less weight, installing/dismounting are simple, have greatly improved conventional efficient.
The utility model comprises test machine clamping rod 1, sample fixed head 2, sample fixed block 3, bolt 4, nut 5 and packing ring 6.Sample fixed head 2 is positioned at the centre of test machine clamping rod 1 and sample fixed block 3, by 1 and two sample fixed block 3 of bolt 4, nut 5 and packing ring 6 and test machine clamping rod, is fixed together; Sample fixed block 3 connects sample fixed head 2 and sample 7.
Sample fixed head 2 and sample fixed block 3 have pilot hole, are generally three.
Test machine clamping rod 1 is positioned at the two ends up and down of fixture, and clamping and the loading of cupping machine are convenient in the bar-shaped design of one end, near the bolt design of sample one end, is convenient to be fixed together by nut 5 and sample fixed head 2.
Sample fixed block 3 connects sample fixed head 2 and sample 7, makes sample 7 stressed even in experimentation, guarantees that the stressed solder joint that is transmitted to of sample 7 is the forward pulling force in vertical direction, corrects the angle defect that sample 7 exists in preparation process.
The test machine clamping rod 1 of a whole set of fixture of the present utility model, sample fixed head 2, sample fixed block 3 are all detachable, and volume small volume and less weight, is applicable on various common tension tester.
Fixture of the present utility model is split type symmetric design, and by bolt, assemble between sample fixed head 2, sample fixed block 3 and sample 7, guaranteed that the sample 7 of angle between 30 °～90 ° can test, reduced difficulty prepared by Automobile Plate solder joint cross stretching experiment sample.
The complete symmetry design of a whole set of fixture of the present utility model, has fully guaranteed that the positive pulling force being applied in experimentation on sample 7 solder joints maintains vertical angle, has guaranteed the accuracy of experimental result.
Test machine clamping rod 1 is connected with cupping machine, is positioned at the upper and lower side of sample, plays a part to be connected with cupping machine with stressed; Sample fixed head 2, is positioned at the upper and lower of sample, with sample fixed block 3 actings in conjunction clamping samples; On sample fixed head 2 and sample fixed block 3, there is pilot hole, by bolt, sample fixed head 2, sample fixed block 3 are effectively connected with sample.
The equal reference coupon dimensions design of sample fixed head and sample fixed block, has guaranteed that experimentation sample is installed convenient and swift, guarantees the stressed even and positive pulling force of experimentation in the vertical direction simultaneously.
While using unit clamp to carry out solder joint cross stretching experiment, along with the loading of cupping machine, the two-piece unit of fixture is with the both sides print both direction extension up and down of sample, until destroy at sample.
Because this sleeve clamp adopts comprehensive symmetrical design for disassembly, realized and on common stretcher, carried out solder joint cross stretching experiment, reduced the preparation requirement of experiment to sample, experimentation has guaranteed the vertical of 4 stressed all even stressed directions, has fully guaranteed the true and accurate of experimental result.
Advantage of the present utility model: realized and carry out solder joint cross stretching experiment on common stretcher.Utilize common steel, pass through unique design, processing and installation and coordinate, safe, to realize efficiently Automobile Plate solder joint cross stretching experiment object has reduced equipment purchase and maintenance cost simultaneously, enrich the means of Automobile Plate research, accelerated the speed of Automobile Plate correlative study.
