Abstract
The utility model provides a sticky experimental special fixture of a shear strength that connects for acrylic acid ester glues shear strength testing, and the structure includes fixture, fixture, fastening bolt and locating lever down, adjusts the position of locating lever through fastening bolt, can the not unidimensional sample of furthest adaptation, with the requirement of satisfying machine assembly, upper and lower fixture are simple C type structure, keep application of force direction and the coincidence of sample major axis, do not produce the annex moment of flexure. The utility model discloses simple structure, convenient to use is applicable to the industrial production.
Description
Technical field
The utility model relates to the frock clamp fixing sample in a kind of shearing test, is especially applicable to the technical field to bonding force shear strength test between material.
Background technology
In the manufacture of aircraft cabin lid and assembling process, adhesive is as important connecting material, and its performance quality directly has influence on product quality and flight safety.Shearing test is mainly used in the shear strength of testing aviation SGA, and its principle is: refer to the peak load being parallel to gluing junction that glue bonding sample can bear in unit are, computing formula is
Wherein,
shear strength (MPa),
pfailing load (N),
b, Vgluing junction length and width (mm) respectively.
For the test of acrylate adhesive shear strength, in technological document, define index of correlation, but detailed regulation is not made, such as load mode, fixture situation etc. to the details of test.Therefore, the utility model, according to the technological requirement used in test, devises the special fixture of applicable regulation sample requirement, has assisted this to test.
Utility model content
The purpose of this utility model is the defect for prior art, and provide a kind of gluing junction shear strength test special fixture, it accurately can facilitate clamping, and fixture and sample do not produce relative movement.
Technical problem described in the utility model solves by the following technical programs:
A kind of gluing junction shear strength test special fixture, comprise jig and lower jig, the head of described upper jig and lower jig is C type, and its hollow bulb is relative, and can be free to slide, the afterbody of upper jig and lower jig arranges connection handle respectively.
Above-mentioned gluing junction shear strength test special fixture, described upper jig and lower jig head periphery arrange spacing ring.
Above-mentioned gluing junction shear strength test special fixture, described lower jig arranges backstay, described backstay is V-type, its knuckle position is threaded connection the head end being assemblied in lower jig, backstay one end support limit ring, the other end supports sample, and the bar of support limit ring arranges fastening bolt.
Above-mentioned gluing junction shear strength test special fixture, described lower jig head end is hollow, and described fastening bolt bottom support face is for become а angle with horizontal plane, and а is 30 ~ 60 °.
Above-mentioned gluing junction shear strength test special fixture, described upper jig and lower jig afterbody arrange connection handle.
The utility model has the following advantages:
The utility model regulates the position of backstay by fastening bolt, farthest can adapt to the sample of different size, to meet the requirement of equipment assembling.Upper and lower jig is simple C type structure, keeps force direction to overlap with sample major axis, does not produce annex moment of flexure.

Fig. 3 is the utility model assembling sample schematic diagram.
In figure, each label represents respectively: 1, upper jig, 2, lower jig, 3, connection handle, 4, spacing ring, 5, backstay, 6, fastening bolt, 7, set bolt.
Detailed description of the invention
Accompanying drawings 1,2, the utility model structure comprises jig 1, lower jig 2 and backstay 5.Upper jig 1 and lower jig 2 are head C type structure, and jig head hollow bulb is oppositely arranged, and in order to clamp sample, its tail end arranges connection handle 3, in order to assemble with stretcher.Upper jig 1 and lower jig 2 head periphery arrange spacing ring 4.
Lower jig 2 arranges backstay 5, described backstay 5 is V-type, its knuckle position is threaded connection and is assemblied in lower jig 2 head end, backstay 5 one end support limit ring, the other end supports sample, the bar of support limit ring is arranged fastening bolt 6, the head end of lower jig 2, the position arranging backstay 5 are hollow, the stress surface of fastening bolt 6 is an inclined-plane, and this inclined-plane becomes а angle with level, and а is 30 ~ 60 °.Backstay 5 and spacing ring 4 acting in conjunction, for limiting the relative position of sample and upper and lower jig, keep its position not change when loading.
Two jigs are set, can quick despatch be carried out, and be convenient for changing sample.Lower jig 2 and upper jig 1 symmetrical configuration, but due to lower jig 2 being provided with backstay 5, lower jig 2 size is slightly larger than upper jig 1.
Accompanying drawings 3, the sample prepared according to technological requirement, when carrying out shearing test, is first assemblied between upper jig 1 and lower jig 2 by the utility model.Sample is T-shaped, sample major part part is placed on the head of lower jig 2, by fastening bolt, regulate the position of locating piece, makes sample just in time between two jigs, keep three's relative position constant.Again spacing ring 4 is enclosed within outside upper and lower jig, then the combination of sample and fixture is assembled on equipment, can shearing test be carried out.
