Abstract
The utility model relates to an automatic testing device for the percentage of elongtation of metal materials. The automatic testing device is characterized by comprising a data acquisition instrument, a stayguy rotating shaft displacement sensor, a universal adjustable sensor bracket, a testing stayguy and two magnetic gripping heads or two special elastic gripping heads, wherein the stayguy rotating shaft displacement sensor is connected with the universal adjustable sensor bracket and is supported by the universal adjustable sensor bracket; one end of the testing stayguy is connected with one magnetic gripping head after passing through a lantern ring on the other magnetic gripping head; the other end of the testing stayguy is tied with a lead weight after rounding an induction wheel on the stayguy rotating shaft displacement sensor; and the stayguy rotating shaft displacement sensor and the data acquisition instrument are connected by a power cord and a signal wire. When the automatic testing device is used, the two magnetic gripping heads are adsorbed on a tested piece, and when the tested piece is stretched in the test, the displacement senor sends a displacement signal to the data acquisition instrument which records and displays the displacement signal. The utility model can automatically carry out continuous strain measurement for the whole test and draw a material mechanics elongtation curve, and has high precision and low price.
Description
Technical field
The utility model relates to a kind of measurement mechanism, particularly a kind of metal material extensibility automatic testing equipment.
Background technology
Tensile property is the key technical indexes and the important evidence of evaluation metal material mechanics performance, and it is the important method of comprehensively, accurately evaluating material property that drafting material power----is extended curve map.At present, the main method of state's build-in test metal material extensibility is to use gauge length machine routing on material, and tension test test specimen fracture back records the gauge length of having no progeny with slide calliper rule, and then calculates the extensibility of material, and manually-operated can only record the gauge length of having no progeny, and degree of accuracy is low.When the needs pinpoint accuracy detects, general electronic extensometer or the laser shooting extensometer of using, but because of electronic extensometer requires height and can't ask for fracture elongation environment for use, be mainly used in the less test of sample deformation, and laser shooting extensometer is difficult to promote the use of in the metal material project of common buildings engineering detects because price is expensive, strict to environment for use.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned weak point, can to carry out continuous strain measurement, drafting material power----extension curve map, degree of accuracy height, the metal material extensibility automatic testing equipment that price is low to whole test and provide a kind of.
Order of the present utility model is achieved in that metal material extensibility automatic testing equipment comprises data collecting instrument, backguy rotating shaft displacement transducer, universal adjustable sensor stand, test backguy and two magnetic chucks or elastic force special carrier.Backguy rotating shaft displacement transducer is connected with universal adjustable sensor stand and by its support, after passing the collar on the magnetic chuck, one of backguy of test is connected with the another magnetic chuck, test backguy other end is a sash weight after walking around induction wheel on the backguy rotating shaft displacement transducer, is connected by power supply, signal wire between backguy rotating shaft displacement transducer and the data collecting instrument.
The utility model is owing to adopt above design, during use, two magnetic chucks are adsorbed on the irony test specimen or the elastic force special carrier is clipped on the non iron test specimen, backguy length between whole two chucks of stretching forefathers wage adjustment equals the original gauge length of test specimen, when test specimen in the test is stretched elongation, backguy length between two chucks increases, sash weight rises, the induction wheel that drives the rotating shaft displacement transducer simultaneously rotates, cause displacement transducer to send displacement signal, become the test specimen development length as calculated behind the data collecting instrument record and be presented on the display screen to data collecting instrument.Can carry out continuous strain measurement, drafting material power----extension curve map automatically to whole test, the degree of accuracy height, price is low.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.
As shown in Figure 1, metal material extensibility automatic testing equipment comprises data collecting instrument 1, backguy rotating shaft displacement transducer 2, universal adjustable sensor stand 3, test backguy 4 and two magnetic chucks 5, then use the elastic force special carrier instead for the non iron test specimen, backguy rotating shaft displacement transducer 2 is fixedlyed connected with universal adjustable sensor stand 3 and by its support, after passing the collar on the magnetic chuck, 4 one of backguys of test are connected with the another magnetic chuck, test backguy 4 other ends are a sash weight 6 after walking around induction wheel on the backguy rotating shaft displacement transducer 2, between backguy rotating shaft displacement transducer 2 and the data collecting instrument 1 by power supply, signal wire connects.
