A protection mechanism 5 is slidably connected on the working box 1 corresponding to between the end positioning mechanism 2 and the rotating mechanism 4. A clamping mechanism 6 for positioning the protection mechanism 5 is arranged on the top of the end positioning mechanism 2.

[0020] Among them, by setting the end positioning mechanism 2, one end of the test piece can be fixedly clamped. Subsequently, the arranged moving mechanism 3 can drive the rotating mechanism 4 to move towards the other end of the test piece, so that the test piece can be fixedly clamped by the end positioning mechanism 2 and the rotating mechanism 4, and then the torsion test can be carried out on the test piece. The arranged protection mechanism 5 can be mutually clamped with the clamping mechanism 6, and when protecting, it can prevent the protection mechanism 5 from moving away from the test piece, ensuring that there are no safety hazards during the torsion test of the test piece.

[0021] Please refer to Figure 1 and Figure 2, the end positioning mechanism 2 includes a first mounting plate 7, a mounting box 8 and a first three-jaw chuck 9. The first mounting plate 7 is fixedly mounted on the top of the working box 1. One side of the first mounting plate 7 is fixedly connected with a first three-jaw chuck 9 through the mounting box 8. The rotating mechanism 4 includes a slide rail 10, a first slider 11, a second mounting plate 12, a second three-jaw chuck 13 and a first driving motor 14. Two groups of slide rails 10 are fixedly mounted on the top of the working box 1. A first slider 11 is slidably connected to the slide rail 10. The top of the first slider 11 is fixedly mounted with a second mounting plate 12. One side of the second mounting plate 12 is fixedly mounted with a first driving motor 14. The output end of the first driving motor 14 is fixedly connected with a second three-jaw chuck 13. Positioning jigs 15 are fixedly mounted on the jaws of the second three-jaw chuck 13 and the first three-jaw chuck 9 through locking bolts.

[0022] Among them, a suitable positioning jig 15 is fixed by using a locking bolt. Then, one end of the test piece is inserted between multiple groups of positioning jigs 15. Then, the first three-jaw chuck 9 is started to work. The first three-jaw chuck 9 can drive the positioning jig 15 to work, and thus one end of the test piece can be fixed. Then, the certain mechanism 3 drives the rotating mechanism 4 to move to the other end of the test piece. Then, the second three-jaw chuck 13 is started to operate, and thus the positioning jig 15 on the second three-jaw chuck 13 can be used to fix the other end of the test piece. Then, the first driving motor 14 operates, and a torsion test can be performed on the clamped test piece.

[0023] Please refer to Figure 1 and Figure 3 , the moving mechanism 3 includes a third mounting plate 16, a threaded rod 17, a second driving motor 18 and a threaded sleeve 19. Two groups of third mounting plates 16 are fixedly mounted on the top of the working box 1. A threaded rod 17 is rotatably connected between the two groups of third mounting plates 16. One end of the third mounting plate 16 is fixedly mounted with a second driving motor 18. The output end of the second driving motor 18 is fixedly connected with the threaded rod 17. The outer surface of the threaded rod 17 is threadedly connected with a threaded sleeve 19 fixedly connected with the second mounting plate 12.

[0024] Among them, when the moving mechanism 3 drives the rotating structure 4 to operate, the second driving motor 18 is started to operate. The second driving motor 18 drives the threaded rod 17 to rotate, and thus the threaded sleeve 19 can be used to push the second mounting plate 12 and the second three-jaw chuck 13 to move along the slide rail 10 to the other end of the test piece.

[0025] Please refer to Figure 1 , Figure 2 and Figure 3, the protection mechanism 5 includes a chute 20, a second slider 21, a mounting seat 22 and a protective cover 23. Chutes 20 are provided on both sides of the working box 1. A second slider 21 is slidably connected inside the chute 20. One side of the second slider 21 is fixedly connected to a mounting seat 22. A protective cover 23 is fixedly connected to the top of the mounting seat 22. A handle 24 is fixedly connected to one side of the protective cover 23.

[0026] Among them, when the test piece is subjected to a torsion test, the handle 23 is pushed to move the protective cover 23 and the second slider 21 along the chute 20. Subsequently, the protective cover 23 can be moved above the test piece for protection.

[0027] Please refer to Figure 1 、 Figure 2 and Figure 4 , the clamping mechanism 6 includes a hinge seat 25, a clamping claw 26, a clamping groove 27, a limiting rod 28, a top plate 29 and a spring 30. An "L"-shaped clamping claw 26 is hinged to the top of the first mounting plate 7 through a hinge seat 25. A clamping groove 27 is formed through the top of the protective cover 23. One end of the chute 20 is slidably connected to a limiting rod 28. One end of the limiting rod 28 is fixedly connected to a top plate 29. A spring 30 is fixedly connected to one side of the top plate 29 and on the outer surface of the limiting rod 28. One end of the spring 30 is fixedly installed inside the chute 20.

[0028] Among them, when the protective cover 23 moves, one end of the protective cover 23 can be limited by the limiting rod 28, the top plate 29 and the spring 30. Subsequently, the clamping claw 26 is clamped inside the clamping groove 27, so that the protective cover 23 can be conveniently limited and fixed, thereby preventing large-range shaking of the protective cover 23 during protection and the occurrence of insufficient protection.

[0029] Please refer to Figure 1 and Figure 2 , the top of the first slider 11 and one side of the second mounting plate 12 are fixedly connected through a first fixing plate 31. The top of the working box 1 and one side of the first mounting plate 7 are fixedly connected through a second fixing plate 32. The provided first fixing plate 31 and second fixing plate 32 can prevent the first mounting plate 7 and the second mounting plate 12 from deforming during the torsion test.

[0030] In use, first, one end of the test piece can be fixedly clamped by setting the end positioning mechanism 2. Subsequently, the moving mechanism 3 can drive the rotating mechanism 4 to move towards the other end of the test piece, so that the test piece can be fixedly clamped by the end positioning mechanism 2 and the rotating mechanism 4. Then, a torsion test can be carried out on the test piece. The provided protection mechanism 5 can be engaged with the clamping mechanism 6, and can prevent the protection mechanism 5 from moving away from the test piece during protection, ensuring that no safety hazards occur during the torsion test of the test piece. Fix the appropriate positioning fixture 15 with a locking bolt. Subsequently, insert one end of the test piece between multiple groups of positioning fixtures 15. Then, start the operation of the first three-jaw chuck 9. The first three-jaw chuck 9 can drive the positioning fixture 15 to work, and thus can fix one end of the test piece. Subsequently, the moving mechanism 3 drives the rotating mechanism 4 to move to the other end of the test piece. Then, start the operation of the second three-jaw chuck 13, so that the positioning fixture 15 on the second three-jaw chuck 13 can fix the other end of the test piece. Subsequently, the first drive motor 14 operates, and a torsion test can be carried out on the test piece after clamping. When the moving mechanism 3 drives the rotating structure 4 to operate, start the operation of the second drive motor 18. The second drive motor 18 drives the threaded rod 17 to rotate, so that the threaded sleeve 19 can push the second mounting plate 12 and the second three-jaw chuck 13 to move along the slide rail 10 towards the other end of the test piece. When the test piece is undergoing a torsion test, push the handle 23 to move the protective cover 23 and the second slider 21 along the chute 20. Subsequently, the protective cover 23 can be moved above the test piece for protection. When the protective cover 23 moves, one end of the protective cover 23 can be limited by the limiting rod 28, the top plate 29 and the spring 30. Subsequently, the clamping claw 26 is clamped inside the clamping groove 27, so that the protective cover 23 can be conveniently limited and fixed, thereby preventing large-range shaking and inadequate protection of the protective cover 23 during protection.
