Description

Technical Field

[0001] This utility model relates to the technical field of cable inspection devices, specifically an inspection device for low-voltage cable production and processing. Background Technology

[0002] Inspection equipment for low-voltage cable production and processing is mainly used to ensure that the electrical performance, mechanical performance and appearance quality of the cable meet the standards, and to ensure the reliability and safety of the cable. It is suitable for the whole process quality control from raw materials to finished products. After the cable completes the insulation extrusion process, it needs to be tested by a spark tester with high voltage electric spark to find defects such as pinholes, cracks or uneven thickness in the insulation layer.

[0003] Traditional spark testing machines require manual adjustment of the electrode spacing, which is not only cumbersome and time-consuming, but also makes it difficult to ensure consistency in adjustment among different operators, directly affecting the test accuracy and reliability. Secondly, the electrode disassembly and replacement process is complicated and usually requires the use of special tools. Frequent replacement of electrodes of different specifications increases the labor intensity of workers and reduces production efficiency. These problems are particularly prominent in continuous, large-scale cable production lines, restricting the efficiency of testing. Utility Model Content

[0015] 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.

[0016] Please see Figures 1-4 As shown, an inspection device for low-voltage cable production and processing includes a mounting base 1, and further includes: The mounting frame 2 is fixedly connected inside the mounting base 1. The mounting base 1 serves as the fundamental supporting component of the inspection device, playing a core supporting role. The mounting frame 2 provides a stable mounting space for transmission components such as the motor 3, the bidirectional threaded rod 4, and the rotating block 5. Through precise internal structural design, it ensures the relative positions of each component are fixed, guaranteeing the coaxiality and stability of the bidirectional threaded rod 4 during rotation, thereby achieving precise adjustment of the distance between the electrodes 16 on both sides. The motor 3 is installed on the right outer wall of the mounting frame 2. The motor 3 is the core power source for adjusting the electrode 16 distance in the inspection device, driving the bidirectional threaded rod 4 to rotate by outputting a stable torque. Utilizing the bidirectional threaded structure of the bidirectional threaded rod 4, it synchronously... The rotating blocks 5 on both sides move axially, thereby linking the electrodes 16 through the connecting column 9 to achieve precise adjustment of the distance between the electrodes 16 on both sides. The drive end of the motor 3 is fixedly connected to a bidirectional threaded rod 4, which can efficiently convert the rotational motion of the motor 3 into the linear motion of the rotating blocks 5 on both sides, driving the electrode 16 components to move closer or further away synchronously, ensuring symmetrical and synchronous distance adjustment, and effectively avoiding detection deviation caused by unilateral adjustment. The external part of the bidirectional threaded rod 4 is set inside the mounting frame 2, and the rotating blocks 5 are threadedly connected to the left and right sides of the outer wall of the bidirectional threaded rod 4. The rotating blocks 5 are the direct transmission objects of the bidirectional threaded rod 4, and the rotating blocks 5 are connected to the bidirectional threaded rod 4 through internal threads. The tightly meshed mechanism precisely converts the rotational motion of the bidirectional threaded rod 4 into its own linear motion. A stabilizing block 6 is rotatably connected to the other end of the bidirectional threaded rod 4. The outer wall of the stabilizing block 6 is fixedly connected to the inner wall of the mounting frame 2. By being fixedly installed on the inner wall of the mounting frame 2, the stabilizing block 6 provides a rigid support point for the non-driving end of the bidirectional threaded rod 4, balancing the axial and radial forces generated during the rotation of the bidirectional threaded rod 4 and preventing bending or swaying of the bidirectional threaded rod 4 due to cantilever stress. A fixing plate 7 is rotatably connected to the outer wall of the bidirectional threaded rod 4. The fixing plate 7 restricts the movement of the bidirectional threaded rod 4 during transmission, ensuring the stability and precision of the threaded transmission. The bottom of the fixing plate 7 is fixedly connected to the mounting frame 2. The inner wall of the fixed plate 7 is located between the two rotating blocks 5. The outer wall of the bidirectional threaded rod 4 is rotatably connected to the rotating plate 8 on the side near the motor 3. The top of each of the two rotating blocks 5 is fixedly connected to the connecting column 9. The top of each of the two connecting columns 9 is fixedly connected to the mounting plate 10. The top of each of the two mounting plates 10 is fixedly connected to the mounting column 11. When the output torque of the motor 3 drives the bidirectional threaded rod 4 to rotate, the structure of the bidirectional threaded rod 4 drives the two rotating blocks 5 to move synchronously along the axial direction. The rotating blocks 5 are linked to the electrodes 16 through the connecting column 9, mounting plate 10, and mounting column 11, thereby precisely adjusting the distance between the electrodes 16 on both sides, providing a suitable detection space for the spark detection of low-voltage cables.

[0017] Both mounting posts 11 are fixedly connected to the top of a mounting base 12. A power supply device 13 is installed inside the mounting base 12. The power supply device 13 is a pulse power supply device, the core power supply component for low-voltage cable spark detection. It provides instantaneous high voltage to the electrodes 16 through high-frequency pulse current output, causing a discharge spark between the electrodes 16. When there are insulation defects on the cable surface, the spark will break down the weak point, forming a current path and triggering a detection alarm, thereby accurately identifying problems such as cable sheath damage and uneven thickness. A quick-connect post 14 is installed on the outer wall of the drive end of the power supply device 13. A threaded post 15 is threadedly connected to the inner wall of the quick-connect post 14. An electrode 16 is fixedly connected to one end of the outer wall of the threaded post 15. The threaded post 15 can provide power to the electrode 16. In the initial installation, the top of the quick-connect post 14 is fixedly connected to the mounting block 17. The mounting block 17 has a sliding pin 18 inside, and the top of the pin 18 is provided with a lever 19. The mounting block 17 has a spring 20 inside, and the inner wall of the spring 20 is set against the outer wall of the pin 18. The top of the threaded post 15 has an installation groove 25, and the bottom of the pin 18 is engaged with the installation groove 25. The electrode 16 is threadedly connected to the quick-connect post 14 through the threaded post 15. Under the action of the spring 20, the pin 18 in the mounting block 17 is engaged into the installation groove 25 of the threaded post 15, realizing the quick installation and fixation of the electrode 16. If the electrode 16 needs to be replaced, the lever 19 is moved to lift the pin 18, and the threaded post 15 and the electrode 16 can be disassembled. The operation is convenient and ensures efficient testing.

[0018] The top of the mounting base 1 is fixedly connected to the base 21, the top of the base 21 is equipped with a receiving plate 22, and the top of the receiving plate 22 is equipped with a clamping block 23. The clamping block 23 can firmly fix the cable to prevent it from shifting or slipping due to vibration, external force or other factors during the testing process, and ensure that the cable is always in the center position of the gap between the electrodes 16. The top of the mounting base 1 is equipped with a control panel 24. The operator can flexibly set the detection voltage, frequency and other parameters through the buttons, knobs and touch screen of the control panel 24. The panel displays the voltage, current and other data in real time, and the indicator lights provide intuitive feedback on the operating status of the equipment. Once an abnormality occurs, an audible and visual alarm will be triggered and fault information will be displayed, which will facilitate quick troubleshooting.

[0019] Working principle: When the device is working and the spacing of electrodes 16 needs to be adjusted, motor 3 is started via control panel 24. Motor 3 outputs stable torque to drive bidirectional threaded rod 4 to rotate. Utilizing the bidirectional threaded structure, it drives the rotating blocks 5 on both sides to move synchronously along the axial direction. Through the linkage of components such as connecting column 9, mounting plate 10, and mounting column 11, the spacing between electrodes 16 on both sides can be precisely adjusted to adapt to the detection of cables of different specifications. The power supply device 13 in the fixed base 12 outputs high-frequency pulse current to provide instantaneous high voltage to electrodes 16, generating discharge sparks between the electrodes to form a detection electric field. When the cable passes through the gap of electrodes 16, if there is an insulation defect, the electric spark will break down the weak point to form a current path, triggering the detection alarm, thereby identifying problems such as surface damage. When it is necessary to replace electrodes 16, the toggle block 19 is moved to lift the pin 18, causing the pin 18 to leave the mounting slot 25, and the electrode 16 is further rotated to complete the disassembly. This quick-release structure can effectively ensure the efficient operation of the detection work.
