Abstract
The utility model discloses a multipurpose fatigue tester, which comprises a base and a drive plate driven by a belt wheel; a plurality of tines are arranged evenly at the periphery of the drive plate, and the distance between each two adjacent tines is equal; the base is provided with a testing spring; one end of the testing spring is fixed on the base, while the other end is inserted into a sample piece; and the sample piece is interfered with the tines of the drive plate. Because of the interference of the tines and a lug boss, the drive plate drives the lug boss to rotate an angle in the rotating process until the lug boss is separated from a tine, and at the moment, the tine swings back under the action of the restoring force of the spring, so a next tine drives the lug boss to rotate again and a cycle is repeated. Through the design, the fatigue strength and service life of the sample piece and the spring are tested. The tester has a simple structure, and is easy to design and manufacture.
Description
Technical field
The utility model relates to the instrument that a kind of part at iterative motion carries out tired and strength test.
Background technology
The utility model is a kind of brand-new design, is a kind of by repeatedly return motion by a small margin, the fatigue strength of test sample spare and spring and life-span.And device itself is simple in structure, is easy to design and make, and cost is low, and result of use is good.
The utility model content
The purpose of this utility model provides a kind of multi-usage testing fatigue instrument, adopts brand-new device to check repeatedly the fatigue strength and the life-span of reciprocating sample coupon and spring, and simple in structure being easy to designed and made.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of multi-usage testing fatigue instrument, comprise base and the dial that drives by belt wheel, dial circumference several moving teeth evenly are set, the distance of adjacent two moving teeth equates, installation testing spring on base, one end of test spring is fixed on the base, and the other end inserts in the sample coupon, and the moving tooth of described sample coupon and dial forms and disturbs.
Because the interference of moving tooth and projection, dial can drive projection and rotate an angle in rotating process, separate the swing back under the effect of spring restoring force of moving tooth this moment with moving tooth up to projection, rotate circulation successively thereby drive projection again by next moving tooth.So can carry out the test in fatigue strength and life-span to sample coupon and spring through above-mentioned design.And instrument itself is simple in structure, be easy to design and make.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural drawing of the described multi-usage testing fatigue of the utility model embodiment instrument
Among the figure:
1, dial; 2, moving tooth; 3, base; 4, test spring; 5, sample coupon.
Embodiment
As shown in Figure 1, multi-usage testing fatigue instrument, comprise base and the dial 1 that drives by belt wheel, dial 1 circumference several moving teeth 2 evenly are set, the distance of adjacent two moving teeth 2 equates that installation testing spring 4 on base 3 is fixed on an end of test spring 4 on the base 3, the other end inserts in the sample coupon 5, and described sample coupon 5 forms interference with the moving tooth 2 of dial 1.
Because the interference of moving tooth 2 and projection, dial 1 can drive projection and rotate an angle in rotating process, separate the swing back under the effect of spring 4 restoring forces of moving tooth 2 this moment with moving tooth 2 up to projection, rotate circulation successively thereby drive projection again by next moving tooth 2.So can carry out the test in fatigue strength and life-span to sample coupon 5 and spring 4 through above-mentioned design.And instrument itself is simple in structure, be easy to design and make.
This device mainly is to be used for testing exemplar pointer intensity and 4 fatigue lifetives of spring. and in the annular space between sample coupon 5 and the base 3, the last ring spring silk that rises that cylindrically coiled spring 4. springs 4 are housed is radially distinguished protruding pin. and an end pin of spring 4 is fixed on the base 3; Other end pin is embedded in the groove of sample coupon 5. and sample coupon 5 outer rims have a projection, being embedded in the open slot on the base 3. projection and open slot are as the pendulum angle of dead stop limits sample coupon 5 rich mandrels, the sidewall of open slot is respectively the spacing up and down of sample coupon 5. this device is exactly to drive dial 1 by belt pulley to rotate, the projection that tooth on the dial 1 promotes the test exemplar rotates, after making that sample coupon 5 and spring 4 rotate to an angle together, the tooth of dial 1 and sample coupon 5 projections break away from, sample coupon 5 rebounds under the effect of spring 4 restoring forces, the sidewall extreme position that makes projection spring back to base 3 open slots stops, and finishes once the test to the test of boss intensity and 4 fatigue lifetives of spring. and motor is finished experiment to sample coupon 5 boss intensity and 4 fatigue lifetives of spring by the belt drags pulley according to certain speed.
