[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 - 8 , in the figure, a strength testing device for cable processing, including a working platform 1, a pay-off reel 2 and a take-up reel 3 are rotatably installed above the working platform 1. The pay-off reel 2 and the take-up reel 3 are horizontally arranged. A workpiece 4 is arranged above the working platform 1. The workpiece 4 is located at the center of the pay-off reel 2 and the take-up reel 3. A support block 9 is installed below the workpiece 4 through a sliding component. A limiting mechanism is arranged on one side of the support block 9 close to the pay-off reel 2. The support block 9 is connected to the working platform 1 through a moving component. Two groups of clamps are arranged above the working platform 1.

[0029] The sliding component includes a base 6 and a groove 8. The groove 8 is opened above the support block 9. The base 6 is slidably inserted into the interior of the groove 8. The base 6 is rotatably connected to the workpiece 4 through a rotating shaft 7. The rotating shaft 7 is vertically arranged.

[0030] Specifically, the cable to be detected is sleeved outside the pay-off reel 2. One end of the cable is wound outside the take-up reel 3. The cable passes through the clamp and bypasses the outside of the workpiece 4. The cable drives the workpiece 4 and the base 6 to move in the groove 8 in the direction of the pay-off reel 2. By moving the support block 9, the workpiece 4 can be driven to move, so that the length of the cable can be adjusted. During this process, the cable can drive the workpiece 4 to rotate around the rotating shaft 7, so as to reduce the friction between the workpiece 4 and the cable and reduce the damage to the cable caused by the workpiece 4.

[0031] The limiting mechanism includes a fixed frame 13. Two groups of sliding grooves 16 are opened inside the fixed frame 13. The sliding grooves 16 are communicated with the groove 8. Two groups of limiting blocks 14 are slidably installed inside the sliding grooves 16 through an adjusting component. An elastic structure is arranged between the two groups of limiting blocks 14.

[0032] The adjusting component includes a mounting block 19 and a push plate 20. The mounting block 19 is slidably inserted into the interior of the groove 8. The mounting block 19 is in contact and cooperation with the base 6. The number of push plates 20 is two. One ends of the two groups of push plates 20 are respectively rotatably connected to both sides of the mounting block 19. The other ends of the two groups of push plates 20 are respectively rotatably connected to the two groups of limiting blocks 14.

[0033] The elastic structure includes a rod 17, which is fixedly installed inside the sliding groove 16. The rod 17 is horizontally arranged and is slidably connected to the limiting block 14. A first spring 18 is movably sleeved outside the rod 17, and the first spring 18 is fixedly connected to the limiting block 14.

[0034] On the adjacent sides of the two groups of limiting blocks 14, protrusions 15 are fixedly installed. On the opposite sides of the two groups of limiting blocks 14, rollers 21 are arranged. The rollers 21 slidably penetrate through the limiting blocks 14, and the rollers 21 are rotatably connected to the fixing frame 13.

[0035] Furthermore, when conducting a tensile test on the cable, the base 6 squeezes the mounting block 19, the mounting block 19 pushes the two push plates 20 to rotate, the push plates 20 drive the limiting blocks 14 to move away from each other outside the rod 17. At this time, the first spring 18 is deformed by the force. The cable passes through between the two groups of limiting blocks 14 and contacts the rollers 21. When the cable breaks during the tensile test, the acting force of the cable on the workpiece 4 disappears. Under the elastic force of the first spring 18, the first spring 18 drives the two groups of limiting blocks 14 to approach each other. Under the action of the protrusions 15, the friction between the limiting blocks 14 and the cable can be increased, enabling the limiting blocks 14 to clamp the cable, so that the cable will not fly off when it breaks, improving the safety of the device and avoiding harm to the surrounding staff when the cable disconnects.

[0036] The moving assembly includes a guide groove 10, which is opened inside the working platform 1. A first threaded rod 11 is rotatably inserted inside the guide groove 10. The first threaded rod 11 is horizontally arranged, and the axis of the first threaded rod 11 is perpendicular to the axis of the winding shaft 2. The first threaded rod 11 is threadedly connected to the support block 9. One end of the first threaded rod 11 is fixedly installed with a motor 12, and the motor 12 is fixedly connected to the working platform 1.

[0037] The fixture includes two groups of support frames 22. The support frames 22 are connected to the working platform 1 through a driving mechanism. Two groups of clamping members 5 are slidably inserted inside the two groups of support frames 22. A second threaded rod 23 is rotatably inserted inside the support frames 22. The second threaded rod 23 is vertically arranged, and the second threaded rod 23 is threadedly connected to the clamping members 5.

[0038] The driving mechanism includes a movable groove 24. A cross bar 25 is fixedly installed inside the movable groove 24. The cross bar 25 is slidably connected to the support frame 22. A second spring 26 is movably sleeved outside the cross bar 25, and the second spring 26 is fixedly connected to the support frame 22. On the side of the two groups of support frames 22 close to the support block 9, push rods 28 are rotatably installed. On the side of the push rods 28 away from the support frames 22, a plate member 27 is rotatably installed. The plate member 27 is in contact and cooperation with the support block 9.

[0039] In the initial state, the support block 9 is in contact with the plate member 27. Under the action of the two groups of push rods 28, the support frame 22 squeezes the second spring 26 inside the movable groove 24, and the second spring 26 deforms under the force. When the support block 9 moves away from the support frame 22, under the elastic force of the second spring 26, the second spring 26 pushes the two groups of support frames 22 to approach each other outside the cross bar 25. When the two groups of support frames 22 come into contact, they stop moving. Rotate the second threaded rod 23 to make the two groups of clamping members 5 approach each other to limit the cable so that the cable will not move. It should be noted that the staff in this field can manually or use tools to drive the rotation of the second threaded rod 23 according to actual needs.

[0040] On one side of one group of support frames 22 close to the other group of support frames 22, an installation groove 33 is provided. Inside the installation groove 33, an adjustment block 32 is slidably installed through a third spring 34. A through hole 35 is provided inside the other group of support frames 22, and the adjustment block 32 and the through hole 35 are inserted and matched. A cross plate 30 slidably penetrates through the inside of the plate member 27. One end of the cross plate 30 close to the adjustment block 32 is fixedly installed with a push rod 29, and the push rod 29 is in contact and cooperation with the adjustment block 32. One end of the cross plate 30 away from the push rod 29 is fixedly installed with a fixed block 31, and the fixed block 31 is in contact and cooperation with the support block 9. Both the fixed block 31 and the plate member 27 have magnetism, and the fixed block 31 and the plate member 27 repel each other.

[0041] Furthermore, when the two groups of support frames 22 are in contact, the adjustment block 32 installed on one group of support frames 22 can be inserted into the inside of the through hole 35 to increase the connection stability between the two groups of support frames 22. Since the plate member 27 and the fixed block 31 repel each other, after the cable test is completed, the support block 9 moves towards the take-up reel 2, the support block 9 contacts the fixed block 31 and drives the fixed block 31 to move. Under the action of the cross plate 30, the fixed block 31 drives the push rod 29 to move. The push rod 29 contacts the adjustment block 32 and pushes the adjustment block 32 into the inside of the installation groove 33. At this time, the third spring 34 is compressed by the force, and the fixed block 31 drives the plate member 27 to move synchronously. The plate member 27 drives the two groups of support frames 22 to move away from each other through the push rod 28.

[0042] Working principle: The cable to be detected is sleeved outside the take-up reel 2. One end of the cable is wound outside the pay-off reel 3. The cable passes through the fixture and bypasses the outside of the workpiece 4. The cable drives the workpiece 4 and the base 6 to move towards the take-up reel 2 inside the groove 8. By moving the support block 9, the workpiece 4 can be driven to move, so that the length of the cable can be adjusted. During this process, the cable can drive the workpiece 4 to rotate around the rotating shaft 7.

[0043] When conducting a tensile test on the cable, the base 6 squeezes the mounting block 19. The mounting block 19 pushes the two sets of push plates 20 to rotate. The push plates 20 drive the limiting blocks 14 to move away from each other outside the rod 17. At this time, the first spring 18 is deformed under force. The cable passes through between the two sets of limiting blocks 14 and contacts the roller 21. When the cable breaks during the tensile test, the acting force of the cable on the workpiece 4 disappears. Under the elastic force of the first spring 18, the first spring 18 drives the two sets of limiting blocks 14 to approach each other. Under the action of the protrusion 15, the friction between the limiting block 14 and the cable can be increased, enabling the limiting block 14 to clamp the cable.

[0044] In the initial state, the support block 9 contacts the plate member 27. Under the action of the two sets of push rods 28, the support frame 22 squeezes the second spring 26 inside the movable groove 24, and the second spring 26 is deformed under force. When the support block 9 moves away from the support frame 22, under the elastic force of the second spring 26, the second spring 26 pushes the two sets of support frames 22 to approach each other outside the cross bar 25. When the two sets of support frames 22 contact, they stop moving. Rotate the second threaded rod 23 to make the two sets of clamping members 5 approach each other to limit the cable so that the cable does not move. It should be noted that those skilled in the art can manually or use tools to drive the rotation of the second threaded rod 23 according to actual needs.

[0045] When the two sets of support frames 22 contact, an adjustment block 32 installed on one of the support frames 22 can be inserted into the through hole 35 to increase the connection stability between the two sets of support frames 22. Since both the plate member 27 and the fixed block 31 are magnetic and repel each other, after the cable test is completed, the support block 9 moves towards the take-up reel 2, the support block 9 contacts the fixed block 31 and drives the fixed block 31 to move. Under the action of the cross plate 30, the fixed block 31 drives the push rod 29 to move. The push rod 29 contacts the adjustment block 32 and pushes the adjustment block 32 into the installation groove 33. At this time, the third spring 34 is compressed. The fixed block 31 then drives the plate member 27 to move synchronously. The plate member 27 drives the two sets of support frames 22 to move away from each other through the push rod 28.
