Establish one group of motor and reduction gear (not shown) on base 106, it is connected with yoke plate 108 by screw rod (in the implicit single-column 100), through 108 liftings of revolution transmission yoke plate.

Pass through said structure, in configuring experiment behind the required experiment condition, tested material is fixedly installed between anchor clamps 104 and the lower clamp 105, when last anchor clamps 104 and lower clamp 105 distances slowly increase, tested material promptly bears its pulling force at leisure, when tested material slowly increased pulling force and ruptures because of bearing, strength sensor 101 can be measured strength numerical value.

But, above-mentioned existing tension tester, it all is simple have only anchor clamps 104 on a group, lower clamp 105 and one group of strength sensor 101, so when doing experiment, once only can make a test specimen, and the data of this test specimen are analyzed, cause its work efficiency not high.

Moreover, above-mentioned existing tension tester is because its point of application is not on the axle center, it is the design that belongs to force unbalance, so planting yoke plate 108 spans of platform machine can not be long, can produce excessive moment because yoke plate 108 spans are long, and influence the life-span of board itself, also can not be long because of yoke plate 108 spans, cause the test space too little, only be fit to the test subsized specimen.

The utility model content

In view of this, fundamental purpose of the present utility model is to provide a kind of carries out many group tensile tests simultaneously and increases the yoke plate span, reaches the tension tester of test balance of power.

For achieving the above object, the technical solution of the utility model is achieved in that a kind of tension tester, at least one cylinder is installed on one base, a group or more liftable yoke plate is installed at cylinder, at the yoke plate downside anchor clamps assembly on a group is installed, last anchor clamps assembly comprises clamping fixture head, latch and strength sensor, is equipped with and the total lower clamp assembly of counting in groups of last anchor clamps in base relative position correspondence, and the lower clamp assembly comprises lower clamp chuck, latch;

Be provided with a motor and a reduction gear at this base, be connected with two groups or more yoke plate by a group or more screw rod, through revolution with the lifting of transmission yoke plate; One group of signal processor is connected with described strength sensor with a micro computer tentative calculation machine or strength display, in order to the numerical value that calculates, analyzes and demonstration records; One revolution is two groups or more yoke plate lifting of transmission, and then drives two groups or more last clamping fixture head, latch and strength sensor.

Upper and lower anchor clamps assembly of above-mentioned two or more sets and yoke plate, it is in order to place fixing thing to be tested;

Above-mentioned and upper and lower anchor clamps assembly, the strength sensor that yoke plate group number is corresponding, it connects with corresponding last anchor clamps assembly respectively, in order to measure the tension variations of these anchor clamps of placing this thing to be tested, to learn the tension intensity degree of this thing to be tested;

Above-mentioned signal processor is connected with described strength sensor with a micro computer computing machine or strength display, in order to the numerical value that calculates, analyzes and the demonstration tension tester records;

Above-mentioned motor apparatus is in order to drive described two or more sets lower clamp assemblies, yoke plate.

The technique effect that the utility model reaches is as follows:

Adopt tension tester of the present utility model, at least one cylinder is installed on the base, a group or more liftable yoke plate is installed at cylinder, many group yoke plate downsides can be equipped with one group on the anchor clamps assembly, can carry out many group tensile tests simultaneously and increase the yoke plate span, reach the test balance of power.Therefore, this tension tester can accurately measure the tension intensity, length growth rate, elasticity coefficient of tested material etc., and significantly promotes conventional efficient, reduces manufacturing cost.
