Description

Technical Field

[0001] This utility model relates to the field of wire testing technology, and in particular to a wire fixing device for a wire testing machine. Background Technology

[0002] Wire testing machines are indispensable professional equipment in the production and quality control of wires and cables. They can accurately evaluate the overall performance of wires by conducting comprehensive physical and electrical performance tests, such as tensile strength, bending performance, conductivity, and insulation resistance. This test data provides valuable feedback to the production line, helping to ensure that each batch of wire meets relevant standards and customer requirements. This effectively guarantees the safety, reliability, and durability of wire and cable products, providing solid technical support for the stable operation of power transmission and signal transmission.

[0003] During use, wire testing machines are usually equipped with a special wire fixing device to ensure that the wire can be placed stably and accurately in the testing position during the testing process, avoiding interference from wire movement or shaking during the testing process, thereby ensuring the accuracy and reliability of the test data.

[0004] When conducting wire testing, the wire needs to be fixed to ensure its stability during testing. However, we have found that the traditional method of fixing the wire by directly wrapping it with a winding rod reduces the flexibility of the wire testing and makes it difficult to adjust the tension of the wire, which is extremely inconvenient. Therefore, there is an urgent need for a wire fixing device for wire testing machines to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a wire fixing device for a wire testing machine, which solves the problem that in the prior art, wires are directly fixed by wrapping with a winding rod, which reduces the flexibility of wire testing and makes it inconvenient to adjust the tension of the wire.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wire fixing device for a wire testing machine includes a frame. Two bearing plates are slidably connected to the inner sides of the frame, and several bearing rods are fixedly connected to the top of the two bearing plates. A side frame is fixedly connected to one side of the frame, and a drive motor is bolted to one side of the outer wall of the side frame. A bidirectional screw is rotatably connected to the inner side of the side frame, with one end of the bidirectional screw penetrating the side wall of the side frame and connected to the output shaft of the drive motor. Both ends of the bidirectional screw are threadedly connected to nut seats, and one side of each nut seat is fixedly connected to one side of each of the two bearing plates. A top frame is fixedly connected to the top of the frame, and a bearing frame is provided inside the top frame. A cylinder is bolted to the top of the top frame, and the output shaft of the cylinder passes through the top of the top frame and is fixedly connected to the top of the bearing frame. A support plate is elastically connected to the inner side of the bearing frame, and several support grooves are provided on the top of the support plate. The top of the support plate is elastically connected to the top of the inner side of the bearing frame through several compression springs.

[0008] Preferably, a slider is fixedly connected to one side of the support plate, and the slider is slidably connected to the inner wall of the support frame through a groove.

[0009] Preferably, a connecting plate is fixedly connected to one side of the bearing frame, and a limiting plate is fixedly connected to one side of the slider. A threaded rod is provided on one side of the limiting plate, and one end of the threaded rod passes through the connecting plate and the limiting plate in sequence through the threaded groove.

[0010] Preferably, a fixing plate is fixedly connected to one side of the frame, and a sliding rod is fixedly connected between the top of the fixing plate and the bottom of the top frame. A sliding sleeve is fitted on one end of the sliding rod, and one side of the sliding sleeve is fixedly connected to one side of the connecting plate.

[0011] Preferably, one end of the bidirectional screw is rotatably connected to the inner wall of the side frame via a rotating shaft, and the other end of the bidirectional screw passes through the side wall of the side frame via a bearing sleeve.

[0012] Preferably, the bottom of the frame is provided with a bottom groove, and a connecting block is fixedly connected to one side of each of the two nut seats. One end of each connecting block penetrates the side wall of the frame, and one side of each connecting block is fixedly connected to one side of each of the two bearing plates.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problems of insufficient flexibility and inconvenient tension adjustment in traditional wire fixing methods. By adopting an alternating winding method of the bearing plate and bearing rod, and the design of the support groove on the support plate, not only is the stability of the wire improved during the testing process, but the fixing of the wire is also more flexible and convenient. The introduction of a cylinder and a drive motor allows the device to test the compressive strength and tensile performance of the wire separately. The cylinder moves the bearing frame downward, stretching and compressing the wire, simulating the pressure that the wire may be subjected to in actual use; while the drive motor drives the bidirectional screw to rotate, realizing the separation of the two bearing plates, thereby performing a tensile test on the wire. This not only improves the accuracy and reliability of the test, but also makes the testing process more automated and efficient. In addition, the elastic connection design of the support plate is also a major highlight of this device. It can not only automatically adjust the support force according to the actual condition of the wire to avoid damage to the wire, but also provide additional stability support for the wire during the test, ensuring the accuracy of the test results.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-5 A wire fixing device for a wire testing machine includes a frame 1. Support plates 2 are slidably connected to both inner sides of the frame 1, and several support rods 3 are fixedly connected to the top of the two support plates 2. A side frame 16 is fixedly connected to one side of the frame 1, and a drive motor 17 is bolted to one side of the outer wall of the side frame 16. A bidirectional screw 18 is rotatably connected to the inner side of the side frame 16, with one end of the bidirectional screw 18 penetrating the side wall of the side frame 16 and drivingly connected to the output shaft of the drive motor 17. Nut seats 19 are threadedly connected to both ends of the bidirectional screw 18, and one side of each nut seat 19 is fixedly connected to one side of each of the two support plates 2. A top frame 4 is fixedly connected to the top of the frame 1, and a support frame 6 is provided inside the top frame 4, serving as a support plate 7. The base provides additional support points for the wires. The support frame 6 allows the support plate 7 to move up and down inside to adapt to the testing requirements of different wires. The support frame 6 is located inside the top frame 4, and the top of the top frame 4 is fixedly connected to the cylinder 5 by bolts. The output shaft of the cylinder 5 passes through the top of the top frame 4 and is fixedly connected to the top of the support frame 6. The support plate 7 is elastically connected to the inside of the support frame 6, and the top of the support plate 7 has several support grooves 8. The top of the support plate 7 is elastically connected to the top of the inside of the support frame 6 by several compression springs 21. The support grooves 8 provide additional space for the wires to pass through, allowing the wires to pass through the support plate 7 in an orderly manner and maintain a stable shape during the test.

[0024] Furthermore, a slider 14 is fixedly connected to one side of the support plate 7, and the slider 14 is slidably connected to the inner wall of the support frame 6 through a groove 15. When the cylinder 5 moves the support frame 6 downward, the support plate 7 moves along with the support frame 6, while the slider 14 slides within the groove 15, ensuring stable and smooth movement of the support plate 7. This design enhances the stability of the support plate 7 during movement, preventing changes in the wire position due to uneven force or deviations during movement, thereby ensuring accurate positioning and stability of the wire during testing.

[0025] Furthermore, a connecting plate 13 is fixedly connected to one side of the support frame 6, and a limiting plate 23 is fixedly connected to one side of the slider 14. A threaded rod 22 is provided on one side of the limiting plate 23. One end of the threaded rod 22 passes through the connecting plate 13 and the limiting plate 23 in sequence through the threaded groove. By rotating the threaded rod 22, the support plate 7 can be limited.

[0026] The effect achieved: This design makes the movement range of the support plate 7 adjustable, and the position of the support plate 7 can be adjusted according to the diameter of different wires and testing requirements, thereby improving the applicability and flexibility of the device.

[0027] Furthermore, a fixing plate 10 is fixedly connected to one side of the frame 1, and a sliding rod 11 is fixedly connected between the top of the fixing plate 10 and the bottom of the top frame 4. A sliding sleeve 12 is fitted on one end of the sliding rod 11, and one side of the sliding sleeve 12 is fixedly connected to one side of the connecting plate 13. This enhances the stability and accuracy of the load-bearing frame 6 during movement, prevents the load-bearing frame 6 from deviating from the predetermined trajectory due to uneven force or external interference, and thus ensures uniform force and accuracy of the wire during the testing process.

[0028] Furthermore, one end of the bidirectional screw 18 is rotatably connected to the inner wall of the side frame 16 via a rotating shaft, and the other end of the bidirectional screw 18 passes through the side wall of the side frame 16 via a bearing sleeve.

[0029] Furthermore, a bottom groove 9 is provided at the bottom of the frame 1. A connecting block 20 is fixedly connected to one side of each of the two nut seats 19, and one end of each connecting block 20 penetrates the side wall of the frame 1. One side of each connecting block 20 is fixedly connected to one side of each of the two bearing plates 2, which enhances the stability and accuracy of the bearing plate 2 during movement and prevents the bearing plate 2 from deviating from the predetermined trajectory due to uneven force or external interference. This ensures uniform force and accuracy of the wire during the tensile test. At the same time, the bottom groove 9 also facilitates the installation and maintenance of the bearing plate 2.

[0030] In summary:

[0031] During operation, the operator first alternately winds the wire to be tested along all the support rods 3 on the two support plates 2. The wire is distributed orderly on the support rods 3 to ensure uniform force application during subsequent testing. Simultaneously, the wire passes through the support grooves 8 on the support plate 7. These grooves provide additional support points for the wire, helping to maintain its stability during testing. After winding and passing the wire through the grooves, the operator activates the cylinder 5. The output shaft of the cylinder 5 passes through the top frame 4, causing the support frame 6 to move downwards. This action stretches and compresses all the wire, simulating the pressure the wire might experience in actual use, to test the wire's compressive strength. By adjusting the pressure and stroke of the cylinder 5, the compressive force on the wire can be precisely controlled, ensuring the accuracy of the test results. During the downward movement of the support frame 6, the support plate 7 moves along with the support frame 6. The slider 14, fixedly connected to one side of the support plate 7, slides within the groove 15, ensuring stable and smooth movement of the support plate 7. This prevents changes in the wire position due to uneven force or deviations during movement, ensuring accurate positioning and stability of the wire during testing. To test the tensile strength of the wire, the operator can start the drive motor 17. The drive motor 17 drives the bidirectional screw 18 to rotate. Since both ends of the bidirectional screw 18 are connected to nut seats 19 by threaded engagement, and one side of each nut seat 19 is fixedly connected to one side of each of the two support plates 2, the rotation of the bidirectional screw 18 will cause the two nut seats 19 to move away from each other, thereby stretching the wire and simulating the deformation of the wire under tensile force to test its tensile strength. One end of the bidirectional screw 18 is rotatably connected to the inner wall of the side frame 16 via a rotating shaft, and the other end passes through the side wall of the side frame 16 via a bearing sleeve, ensuring the rotational stability and durability of the bidirectional screw 18. In addition, a connecting plate 13 is fixedly connected to one side of the bearing frame 6, and a limiting plate 23 is fixedly connected to one side of the slider 14. A threaded rod 22 is provided on one side of the limiting plate 23, and one end of the threaded rod 22 passes through the connecting plate 13 and the limiting plate 23 sequentially via threaded grooves. By rotating the threaded rod 22, the support plate 7 can be limited, making the movement range of the support plate 7 adjustable. The position of the support plate 7 can be adjusted according to the diameter of different wires and testing requirements, improving the applicability and flexibility of the device. A fixing plate 10 is also fixedly connected to one side of the frame 1. A sliding rod 11 is fixedly connected between the top of the fixing plate 10 and the bottom of the top frame 4. A sliding sleeve 12 is fitted onto one end of the sliding rod 11, and one side of the sliding sleeve 12 is fixedly connected to one side of the connecting plate 13. This design enhances the stability and accuracy of the support frame 6 during movement, preventing it from deviating from the predetermined trajectory due to uneven force or external interference, and ensuring uniform force and accuracy of the wire during testing. A bottom groove 9 is provided at the bottom of the frame 1, and connecting blocks 20 are fixedly connected to one side of each of the two nut seats 19. One end of each connecting block 20 penetrates the side wall of the frame 1 and is fixedly connected to one side of the support plate 2.This design enhances the stability and accuracy of the support plate 2 during movement, preventing it from deviating from its predetermined trajectory due to uneven force or external interference, thus ensuring uniform force and accuracy of the wire during tensile testing. Simultaneously, the bottom groove 9 facilitates the installation and maintenance of the support plate 2.
