This screw hole 143 is equipped with a compression jig (Jig, 16 ', see Figure 1) for compression or tensile test. The reason why the screw hole 143 is formed around the insertion hole 141 is because the rotational center of the rotation plate 140 becomes the insertion hole 141, so that the direction of the load when used for the compression test or the tension test is used. This is to gather into the insertion hole (141).

In addition, the guide groove 144 is formed in the longitudinal direction in the center on the upper surface of the rotating plate 140. Guide groove 144 is a cross-sectional shape of the "ㅗ" shape, and is formed to extend from the position adjacent to the insertion hole 141 to both ends.

The body 151 is formed on the rotating plate 140 at the center of the bottom surface of the bottom plate 151 ′. A guide 152 having a shape corresponding to the guide groove 144 is coupled. The guide 152 is screwed with the lever 153 on the upper surface of the bottom plate 151 'to release the lever 153. In this case, the guide groove 144 can be moved freely, and locking the lever 153 clamps the guide groove 144 while suppressing the movement of the body 151. And on both sides of the bottom surface of the bottom plate 151 '. The auxiliary guide 154 protruding to correspond to the auxiliary guide groove 145 may be further formed integrally, that is, when the body 151 is operated only by the guide 152 and the guide groove 144, it may be shaken or smoothly. Since it may not be able to move so as to further support the auxiliary guide 154 and the auxiliary guide groove 145 to support it.

Next, the pressing plate 155 is coupled on opposite sides of the side plate 151 ″, and is coupled by fixing bolts 156. On the opposite facing sides of the pressing plate 155, pads (back) are provided. 157. The pad 157 is preferably a resilient rubber material, and a plurality of protrusions 158 are formed on the pad 157. Here, the pressing plate coupled by the fixing bolts 156 is attached thereto. 155 may be attached to the body 151 by the adjustment of the fixing bolt 156 or may be spaced apart from the body 151 at a predetermined interval.

Next, the locking plate 160 is coupled to the upper portion of the body 151. The locking plate 160 is coupled to an upper portion of the side plate 151 ″ and is formed out of the pressing plate 155. The locking plate 160 has a coupling plate 161 to be coupled to the side plate 151 ″. It is integrally formed with the locking plate 160 at a right angle. At this time, the central portion of the coupling plate 161 is formed with a groove 162 cut in the longitudinal direction of the long hole shape, the fixing bolt 163 is fastened to the groove 162, the coupling plate 161 and the side plate 151 ". And a seating surface in which the coupling plate 161 is seated on the side of the side plate 151 ″ in which the coupling plate 161 is in contact so that the coupling plate 161 is in close contact with the side plate 151. 165 is formed, and a bolt hole 166 to which the fixing bolt 163 is fastened to the center of the seating surface 165 is formed.

Hereinafter, the operating state of the material tester vise device 100 formed as described above will be briefly described. Here only the operating conditions for the tensile test will be described.

First, the vise device 100 according to the present invention is mounted on the universal testing machine 10, and then the bite jig 16 ′ is attached to the screw hole 143 of the rotating plate 140. Therefore, the biting jig 16 'is mounted on the lifting unit 13 and one on the vise device 100 to face each other to fix the specimen for tensile test on both bite jig (16, 16').

Here, in the past, the upper bite jig 16 and the lower bite jig 16 'had to be adjusted to be fitted in the longitudinal direction, but the vise device 100 according to the present invention is mounted so as not to be penetrated. It is irrelevant.

In this state, the universal testing machine 10 is operated to raise and lower the elevating part 13 while the specimen is pulled, and the Y-axis feed plate 130 and the X-axis feed plate 120 are naturally centered. Therefore, in the tensile test using the bite jig 16 ′, the vise part 150 may be omitted.

On the other hand, there is also a need to test whether the sample is released to what load after the specimen is mounted on the specimen, instead of testing only with the specimen. Therefore, in this case, the vice unit 150 may fix the specimen itself.

That is, by operating the lever 153 in accordance with the width of the test piece to allow the vise 150 to be spaced apart from each other, and according to the height of the test article by adjusting the fixing bolt 163 of the locking plate (160) 160) height can be adjusted. In addition, the rotating plate 140 may be rotated by a predetermined angle. That is, the rotating plate 140 and the Y-axis feed plate 130 is connected to the stop ball 133 and the stop groove 146, so that the interval of the stop groove 146 is formed at equal intervals, for example 5 ° , The rotating plate 140 is to be constantly rotated at such an angular interval.

The fixed specimen is fixed by the pressing plate 155, but the locking plate 160 is positioned above the specimen in order to suppress the upward movement when a tensile load is applied.
