Description
Technical field
The present invention relates to a kind of glass test fixture, classification number: G01N3/04, particularly relating to so a kind of surrounding can zoom in or out, and for Hua Zhu isoplanar, the wheel slideway four limit nickel alloy alignment jig of tested glass intensity.
Background technology
Glass is one of the most ancient material that it is found that and utilize.Before 3500, just there has been the technology of the simple glass implements of making in ancient Egypt, the jewelry of man-made glass and China has also been unearthed in the grave in the Western Zhou Dynasty.Along with the development of science and technology, glass develops rapid especially within the nearly centenary time, and glass has become requisite a kind of material in mankind's daily life.Along with expanding economy, glass is more and more extensive in the application of all trades and professions.Glass can be used as glass curtain wall, glass door and window etc. between floors, and can be used as teacup, bottle, light fixture etc. in daily necessities, in industrial machinery, glass can be used as transparent sight hole, glass door etc.
At present, much important glass component, such as large glass curtain wall and glass zenith, the windshield of aerospace vehicle is all adopt the special glasss such as safety glass, requires very strict, therefore check the performance of glass just to seem more and more important to glass properties.From 1 day May in 2003, China implements mandatory inspection system to automobile, train, architectural safety glass used, and the safety glass product not obtaining Compulsory Certification of Products certificate and do not apply China Compulsory Product Certification mark must not dispatch from the factory, import and sale.
Fragmentation test is a kind of major way detecting tempered glass quality, according to national standard requirement, fragment after the fragmentation of the safety glass that 3mm is thick in any 50*50mm should be greater than 30, fragment after the fragmentation of the safety glass that 4mm ~ 12mm is thick in any 50*50mm should be greater than 40, allowed a small amount of strip fragment, its length is no more than 75mm.The trend of strip fragment and glass edge should be almost parallel, and as not parallel, angle can not more than 45 degree, if having one not up to standard, be substandard product.
Existing safety glass fragmentation test method is freely lain on testing stand by safety glass sample, and retrain glass periphery by adhesive tape or other modes, or cover thin film on safety glass, splashes to prevent glass fragment.The position of distance periphery about 20mm on the longest edge center line of sample, be that the pane hammer of 0.2mm scholar 0.05mm or drift impact with tip curvature radius, making sample broken, is that the fragment number in center of circle radius 75mm circle does not conduct a survey within the scope of product edges 20mm and with shock point.The measure retaining fragment pattern should start after 10s after the blow and terminate in 3min after the blow.This method not only operates inconvenience, spended time is longer, and adhesive tape is disposable product, easily cause waste and pollute, and the tape residue on testboard flat board must be removed clean after each test, could remove clean cullet, otherwise residual chopped glass will affect experiment test operation next time.
Simultaneously adhesive tape also has and is burst by safety glass the possibility that strength collapses out, and causing operating personnel injured, therefore, is very necessary to the improvement of safety glass fragmentation test device.
Chinese Patent Application No.: 201420595067.X, safety glass fragmentation status experimental rig, propose some brand-new method and measures and deal with the fixing of brittle glass, but cannot accomplish that arbitrary dimension regulates, also cannot accomplish to allow four limit pressing plates all at grade.At least to have in this patent while be cannot contact with experiment work table top.Simultaneously the unsettled barricade 5 that is referred to as in embodiment cannot contact with base 1 together with other three side bumpers wall, has to use catch 4 to make up the space between unsettled barricade 5 and base 1, cause surrounding discontinuity.In addition, catch 4 local width is fixing, polylith can only be adopted to splice, cannot accomplish the consecutive variations of different in width.
