Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of engineering detection, in particular to a steel plate thickness direction tensile test tool. BACKGROUND

[0002] When the steel plate has thickness direction performance requirements, thickness direction tensile test should be carried out. Figure 1 As shown, the dumbbell-shaped sample 1 should be prepared in the thickness direction of the steel plate or the thread rolling is carried out on both ends of the columnar sample 2, and then different test tools are matched to be loaded into the testing machine for testing. However, the processing difficulty of thread rolling on the sample is relatively large, and the total length of the dumbbell-shaped sample 1 in the thickness direction can only be less than or equal to the thickness of the steel plate, especially the sample of the steel plate with a thickness of 15 mm~400 mm is relatively small, which is difficult to be installed and matched with the test tool and loaded into the testing machine.

DETAILED DESCRIPTION

[0023] To make the purposes, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0024] As shown in Figures 2 to 7 , the steel plate thickness direction tensile test tool of the embodiment comprises an upper clamp 10 and a lower clamp 20.

[0025] As shown in Figure 2 , the upper clamp 10 comprises a clamping tool 11, a threaded tool 12, and a connecting rod 13;

[0026] The side wall of the clamping tool 11 has a clamping groove 111, the bottom of the clamping groove 111 is an opening 112 communicating with the bottom of the clamping tool 11, and the left and right sides of the opening 112 have two oppositely extending clamping edges 113; the top of the clamping tool 11 has a first threaded through hole 114 communicating with the clamping groove 111;

[0027] The threaded tool 12 has a second threaded through hole 121 penetrating from top to bottom;

[0028] The upper part of the connecting rod 13 is a round rod 131, and the lower part is a threaded rod 132, which is movably screwed into the first threaded through hole 114 and / or the second threaded through hole 121;

[0029] The structure of the lower clamp 20 is symmetrical to that of the upper clamp 10, that is, the lower clamp 20 also has a clamping tool 11, a threaded tool 12, and a connecting rod 13.

[0030] In this way, the round rod 131 of the connecting rod 13 is connected to a testing machine (not shown in the figure), and then the clamping tool 11 or the threaded tool 12 can be selected and installed as needed to fix and perform tensile tests on the columnar sample 2 or the dumbbell-shaped sample 1, which can improve the convenience of using the tool. In particular, as shown in Figure 3 , when the dumbbell-shaped sample 1 with a small steel plate thickness is used, there is no need to roll threads, which can reduce the processing difficulty, and then the clamping tool 11 and the connecting rod 13 are matched to clamp the two ends of the dumbbell-shaped sample 1 into the clamping groove 111 of the clamping tool 11 of the upper clamp 10 and the lower clamp 20, respectively, the clamping edges 113 can be used to limit the two ends of the dumbbell-shaped sample 1, and the threaded rod 132 of the connecting rod 13 can be screwed into the first threaded through hole 114 to position and fix the end of the dumbbell-shaped sample 1, which can prevent the dumbbell-shaped sample 1 from falling out of the clamping groove 111, facilitate the installation of the sample, and facilitate the installation of the sample and the upper clamp 10 and the lower clamp 20 on the testing machine.

[0031] For the cylindrical sample 2, referring to Figure 4 , the two ends of the cylindrical sample 2 need to be rolled to be screwed into the second threaded through hole 121 of the threaded tool 12 of the upper clamp 10 and the lower clamp 20 respectively for fixation, and the threaded rod 132 of the corresponding connecting rod 13 is also inserted into the second threaded through hole 121 for fixation.

[0032] Referring to Figure 5 , the length of the threaded rod 132 in the embodiment can be not less than the sum of the axial lengths of the first threaded through hole 114 and the second threaded through hole 121. Therefore, the clamping tool 11, the threaded tool 12 and the connecting rod 13 can be combined for use, and the threaded rod 132 of the connecting rod 13 is inserted into the second threaded through hole 121 and the first threaded through hole 114 in turn, so that the clamping tool 11 and the threaded tool 12 are stacked and matched with each other.

[0033] As Figure 7 , the clamping groove 111 extends through the clamping tool 11 front and back to facilitate the installation of the dumbbell-shaped sample 1, and the threaded rod 132 of the connecting rod 13 can be used to position and fix the dumbbell-shaped sample 1.

[0034] As Figure 2 , the clamping edge 113 has a first step 115 and a second step 116 to facilitate limiting and fixing.

[0035] As Figure 2 , Figure 6 and Figure 7 , the clamping tool 11 and the threaded tool 12 in the embodiment can be discs with the same diameter.
