Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, specifically a cable tensile strength testing device. Background Technology

[0002] A cable is a wire device used to transmit electrical energy, signals, or data. It typically consists of one or more conductive cores, an insulation layer, a protective layer, and other auxiliary structures. It is widely used in power, communication, industrial control, construction, and other fields. To ensure the safety of cables during use, tensile strength testing is required during the cable production and processing.

[0003] In existing cable tensile strength testing technologies, most tensile strength testing devices have complex operation problems when fixing cables and are difficult to adapt to cables of different specifications and sizes. This makes the testing process inconvenient and inefficient, and also limits the applicability of the device, affecting the accuracy and comprehensiveness of the test results.

[0004] Therefore, there is a need for a cable tensile strength testing device to solve the problems of existing tensile strength testing devices being complex to operate when fixing cables and difficult to apply to cables of different specifications. Utility Model Content

[0005] The purpose of this invention is to provide a cable tensile strength testing device to solve the problem that the existing tensile strength testing devices are complicated to operate when fixing cables and are difficult to apply to cables of different specifications.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable tensile strength testing device, comprising a base, two parallel sliding grooves opened on the top surface of the base, a slider movably installed inside the sliding groove, a same movable plate installed on the top surface of the two sliders, and a fixed plate installed on the top surface of the base, wherein the movable plate and the fixed plate are each provided with a clamping mechanism;

[0007] The clamping mechanism includes a vertical plate, multiple circumferentially distributed guide grooves extending through the side of the vertical plate, a guide block slidably installed inside the guide grooves, a clamping block installed on one side of the guide block, an arc-shaped rod rotatably installed on the other side of the guide block, a rotating ring rotatably installed on one side of the multiple arc-shaped rods, a toothed ring coaxially installed on the outer surface of the rotating ring, and a through hole extending through the center of the side of the vertical plate.

[0008] It should be noted in the solution that a mounting plate is installed on one side of each of the two vertical plates, and a cylinder is installed on the top surface of the mounting plate. The output end of the cylinder slides through the bottom surface of the mounting plate and is equipped with a rack that meshes with the corresponding gear ring.

[0009] It is worth noting that an installation groove is provided on the top surface of the base between the two sliding grooves. A lead screw is rotatably installed inside the installation groove. A moving block connected to a moving plate is movably installed on the outer surface of the lead screw. A servo motor for driving the lead screw to rotate is installed on one side of the base.

[0010] Furthermore, it should be noted that two symmetrically distributed scales are installed on the top surface of the base, and pointers are installed at both ends of the movable plate.

[0011] In a preferred embodiment, the two vertical plates are respectively mounted on the top surfaces of the movable plate and the fixed plate, and the movable block is slidably engaged with the mounting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] A cylinder drives a rack to move, which in turn drives a gear ring to rotate a rotating ring. The rotating ring pulls an arc-shaped rod to move, causing a clamping block to clamp and fix the cable. A servo motor drives a lead screw to rotate, causing the moving block to move a moving plate, which in turn moves one end of the cable. With the help of a pointer and a scale, the movement distance of the moving plate is precisely controlled, allowing for observation of the cable's condition during testing. This makes the test results more accurate and effectively avoids the problems of complex operation and difficulty in applying different specifications of cables when fixing cables using tensile strength testing devices.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figures 1-4 As shown, this utility model provides a technical solution, including a base 1, two parallel sliding grooves 2 opened on the top surface of the base 1, a slider 3 movably installed inside the sliding groove 2, a moving plate 4 installed on the top surface of the two sliders 3, and a fixed plate 5 installed on the top surface of the base 1. Both the moving plate 4 and the fixed plate 5 are provided with clamping mechanisms 6.

[0021] The clamping mechanism 6 includes a vertical plate 61, a plurality of circumferentially distributed guide grooves 62 extending through the side of the vertical plate 61, a guide block 63 slidably installed inside the guide grooves 62, a clamping block 64 installed on one side of the guide block 63, an arc-shaped rod 65 rotatably installed on the other side of the guide block 63, a rotating ring 66 rotatably installed on one side of the plurality of arc-shaped rods 65, a toothed ring 67 coaxially installed on the outer surface of the rotating ring 66, and a through hole 68 extending through the center of the side of the vertical plate 61.

[0022] Specifically, the two ends of the cable to be tested are placed into the through holes 68 on the two vertical plates 61 respectively. Then, when the rotating ring 66 rotates, the arc rod 65 drives multiple clamping blocks 64 to move simultaneously. The multiple clamping blocks 64 clamp the cable to be tested, thereby fixing the cable to be tested. It can be applied to cables of different specifications within a certain range, thus improving the applicability of the device.

[0023] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that each of the two vertical plates 61 has a mounting plate 7 installed on one side. A cylinder 8 is installed on the top surface of the mounting plate 7. The output end of the cylinder 8 slides through the bottom surface of the mounting plate 7 and is equipped with a rack 9 that meshes with the corresponding gear ring 67.

[0024] Specifically, after placing both ends of the cable to be tested into the through holes 68 on the two vertical plates 61, the cylinder 8 is activated to push the rack 9 downward. The rack 9 drives the corresponding toothed ring 67 to rotate, so as to drive the rotating ring 66 to rotate and achieve the above clamping operation.

[0025] Further as Figure 1 and Figure 4As shown, it is worth noting that an installation groove 10 is provided on the top surface of the base 1 between the two sliding grooves 2. A lead screw 11 is rotatably installed inside the installation groove 10. A moving block 12 connected to the moving plate 4 is movably installed on the outer surface of the lead screw 11. A servo motor 13 for driving the lead screw 11 to rotate is installed on one side of the base 1.

[0026] Specifically, after the cable is fixed, the servo motor 13 is turned on to drive the lead screw 11 to rotate. The lead screw 11 drives the moving block 12 to move the moving plate 4, thereby moving one end of the cable to perform tensile testing on the cable.

[0027] Further as Figure 1 and Figure 4 As shown, it is worth noting that two symmetrically distributed scales 14 are installed on the top surface of the base 1, and pointers 15 are installed at both ends of the movable plate 4.

[0028] Specifically, when the moving plate 4 moves, it drives the pointer 15 to move as well. In conjunction with the scale 14, a more precise pulling force can be applied to the cable as needed, and the state of the cable under different pulling forces can be observed, thereby obtaining more accurate test results.

[0029] Further as Figure 1 and Figure 4 As shown, it is worth noting that the two vertical plates 61 are respectively installed on the top surfaces of the movable plate 4 and the fixed plate 5, and the movable block 12 is slidably engaged with the mounting groove 10.

[0030] Specifically, two vertical plates 61 are respectively installed on the top surfaces of the movable plate 4 and the fixed plate 5, so that one vertical plate 61 is fixed and the other vertical plate 61 is movable, so as to facilitate the normal implementation of tensile testing. The movable block 12 slides with the mounting groove 10, which guides the movement of the movable plate 4 and improves the stability of the movable plate 4 when it moves.

[0031] In summary: When using this device, firstly, place both ends of the cable to be tested into the through holes 68 on the two vertical plates 61. Then, activate the two cylinders 8. The cylinders 8 push the rack 9 downwards. Under meshing action, the rack 9 drives the gear ring 67 to rotate, causing the rotating ring 66 to rotate. When the rotating ring 66 rotates, it pulls the arc-shaped rod 65, thereby pulling multiple guide blocks 63 to move simultaneously. The multiple guide blocks 63 move along the corresponding guide grooves 62, causing multiple clamping blocks 64 to move simultaneously towards the center of the through hole 68. Under the action of the multiple clamping blocks 64, the two ends of the cable to be tested are clamped and fixed. Then, activate the servo motor 13 to drive the lead screw 1. 1. Rotation, under the action of the thread, the lead screw 11 drives the moving block 12 to move inside the mounting groove 10. With the cooperation of the sliding groove 2 and the slider 3, the moving plate 4 moves laterally on the top surface of the base 1, pulling one end of the cable to move, thereby performing tensile strength testing on the cable. With the cooperation of the pointer 15 and the scale 14, the moving distance of the moving plate 4 can be precisely controlled, thereby observing the state of the cable during the test and making the test results more accurate. At the same time, this device can be applied to cables of different sizes and specifications, improving the applicability of the device and effectively avoiding the problem that the operation of the tensile strength testing device is more complicated when fixing the cable and it is difficult to apply to cables of different specifications.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
