Description

Technical Field

[0001] The present invention belongs to the technical field of cable detection, and specifically relates to an electronic communication cable detection device. Background Art

[0002] In the field of electronic communication, as an important carrier for transmitting signals, the quality and performance of cables are directly related to the stability and reliability of the entire communication system. Therefore, cable detection is a key link to ensure communication quality and prevent faults. Cable detection mainly includes the detection of cable insulation performance, anti-interference performance, tensile strength, and surface defects.

[0003] The traditional cable detection method is to clamp a section of the cable to be tested on a workbench for detection. It is necessary to detect not only the performance parameters of the cable under normal working conditions, but also to connect an insulation tester and a dielectric loss tester to test the working parameters of the cable under extreme conditions. However, such a test has various limitations. First, the traditional method has a single detection direction and can only use an insulation tester or a dielectric loss tester to detect a specific performance of the cable, which cannot meet the comprehensive and efficient detection requirements. Second, the traditional method usually requires manual participation, such as manually advancing the cable, adjusting the length, and observing the detection results. This not only has low efficiency but also may increase human errors. In addition, the traditional clamping method can only stably clamp a cable with a certain diameter or a thicker cable, and cannot adaptively clamp a cable with a smaller diameter. This not only affects the detection flexibility of the detection instrument, increases unnecessary detection instrument costs, but also may cause bending and extrusion of the cable to be tested due to unstable clamping, affecting the accuracy of the cable detection results. Unstable clamping may also cause problems such as insulation layer rupture and wire deformation.

[0004] Therefore, it is necessary to propose an electronic communication cable detection device that can adaptively clamp communication cables of different diameter specifications stably, can realize automatic cable advancement for detection, and can detect multiple indicators. Summary of the Invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide an electronic communication cable detection device. By adaptively and hierarchically clamping cables of different diameter specifications, the stability of the clamping is ensured. The pressure sensors on the stable clamping surface cooperate with electrical performance detection instruments to integrate multiple detection methods for communication cables, which not only reduces the detection cost, but also improves the detection accuracy and avoids damage to the cable to be tested during the detection process.

[0006] To achieve the above object, the technical solution of the present invention is as follows: An electronic communication cable detection device, comprising a workbench, an insulation tester, and a dielectric loss tester. There is a darkroom on the workbench. Through openings are symmetrically formed on the axial side walls of the darkroom, and light-shielding curtains are fixedly connected to the through openings. A flaw detection component is fixedly connected inside the darkroom, and a roller component is fixedly connected to the outer side wall of the darkroom. Multistage clamping components are symmetrically and fixedly connected to the top of the workbench on both sides of the darkroom. A controller is fixedly connected to the workbench. The tail conductor and the metal sheath of the cable to be tested are respectively fixedly connected to the positive and negative electrodes of the insulation tester, and both ends of the conductor of the cable to be tested are fixedly connected to the dielectric loss tester. The flaw detection component, the roller component, the multistage clamping component, the insulation tester, and the dielectric loss tester are all in signal connection with the controller;

[0007] The flaw detection component is used to dynamically identify the diameter uniformity of the cable to be tested, as well as surface flaws such as surface bulges, pits, and scratches by using real-time image acquisition technology and image recognition technology; the roller component is used to clamp the cable to be tested to limit shaking and drive the cable to be tested to move axially to achieve automatic detection; the multistage clamping component is used to adaptively and stably clamp cables of different diameters through radial progressive clamping and clutch principles, and cooperate with the insulation tester and the dielectric loss tester to perform tensile strength and compressive performance tests on the cable to be tested.

[0008] The principle of the basic solution is: The multistage clamping component can adaptively and hierarchically clamp cables of different diameter specifications through multistage clutch progressive rotation. This design not only ensures the stability of clamping but also avoids damaging the cable due to excessive clamping force. The flaw detection component uses real-time images and image processing technology to dynamically identify the diameter uniformity of the cable to be tested and surface flaws such as bulges, pits, and scratches, and then marks the flaw locations for convenient later improvement and identification. The insulation tester and the dielectric loss tester are respectively connected to the tail conductor and the metal sheath of the cable to be tested, as well as both ends of the conductor, for performing electrical performance tests. They cooperate with the multistage clamping component with a clamping pressure detection function to apply strong pressure or tension to the cable to be tested according to preset and controller control, so as to detect whether the electrical performance of the cable to be tested meets the standards under these physical conditions.

[0009] The beneficial effects of the basic solution are: 1. The multistage clamping component designed by multistage clutch progressive rotation can adaptively and hierarchically clamp cables of different diameter specifications. This design ensures the stability of clamping and at the same time avoids damaging the cable due to excessive clamping force, thus protecting the integrity of the cable.

[0010] 2. The device integrates multiple functional modules such as a defect detection component, an insulation tester, and a dielectric loss tester, and can perform various detections on communication cables on the same instrument. This includes detections in multiple aspects such as diameter uniformity, surface defects, insulation performance, and dielectric loss, so as to apply external forces in different directions to evaluate the quality of the cable.

[0011] 3. The introduction of the roller assembly realizes the automatic clamping and movement of the cable, simplifies the detection process, and improves the detection efficiency. At the same time, the signal connection between the controller and each component makes the entire detection process more intelligent and can automatically execute detection tasks according to the preset program.

[0012] 4. Through the integrated design, multiple detection functions are integrated on one instrument, reducing the number and cost of detection equipment. At the same time, the automated and intelligent detection process also reduces the need for manual intervention, further reducing the detection cost.

[0013] Further, each multi-stage clamping component includes an annular shell. Inside the annular shell, a front toothed ring and a rear toothed ring that are parallel to each other are coaxially and slidably sleeved. On the sides of the front toothed ring and the rear toothed ring that are away from each other, spiral racks are fixedly connected. On the inner wall of the annular shell close to the front toothed ring, a number of radially arranged front sliding grooves are opened. In each front sliding groove, a front slider is slidably fitted. On the side wall of each front slider close to the front toothed ring, a first arc tooth is opened. Each first arc tooth meshes with the spiral rack on the front toothed ring. On the inner wall of the annular shell close to the rear toothed ring, a number of radially arranged rear sliding grooves corresponding to the front sliding grooves are opened. In each rear sliding groove, a rear slider is slidably fitted. On the side wall of each rear slider close to the rear toothed ring, a second arc tooth is opened. Each second arc tooth meshes with the spiral rack on the rear toothed ring;

[0014] On the side wall of each front slider close to the center of the front toothed ring, a connecting block is fixedly connected. On the side wall of each connecting block, a hollow clamping column is fixedly connected. The clamping columns are all located between the front toothed ring and the rear toothed ring and face the center of the annular shell. On the side wall of each clamping column close to the rear toothed ring, a rod sliding groove is opened. At one end of each clamping column close to the center of the annular shell, an arc-shaped kit is fixedly sleeved. The arc-shaped kits in the same annular shell can be spliced into a ring-shaped column. On the side wall of each rear slider close to the center of the rear toothed ring, a connecting rod is fixedly connected. The connecting rod is slidably fitted with the corresponding rod sliding groove. At the end of each connecting rod, a clamping rod is fixedly connected. The clamping rods are all coaxially sleeved inside the corresponding clamping columns. The ends of the clamping rods coincide with the circumferential vertices of the corresponding arc-shaped kits, and arc grooves with a radian greater than that of the arc-shaped kits are opened at the ends of the clamping rods. The arc grooves in the same annular shell can be spliced into a cylindrical shape. Pressure sensors are laid in both the arc-shaped kits and the arc grooves, and the pressure sensors are all signal-connected to the controller.

[0015] The beneficial effects of the basic solution are as follows: 1. The multi-stage clamping assembly realizes the adaptive adjustment of the clamping specifications through the spiral racks of the front tooth ring and the rear tooth ring meshing with the arc teeth of the front slider and the rear slider in the annular shell. Regardless of the cable diameter, the clamping assembly can automatically adjust the clamping force and specifications by the spiral advancement of the two sliders, ensuring that the cable is stably clamped without being over-tightened.

[0016] 2. The combined design of the connecting block, the clamping column, the arc-shaped kit and the clamping rod makes the clamping process more precise. The cylindrical structure formed by multiple clamping columns and arc-shaped kits can closely fit the surface of the cable, and the clamping rod further enhances the clamping stability through the cooperation with the arc-shaped kit through the arc-shaped groove, and can change the clamping specifications to adapt to cables of different thicknesses. This design ensures the fixed position of the cable during the detection process and reduces the detection error caused by shaking.

[0017] 3. The pressure sensors laid in the arc-shaped kit and the arc-shaped groove can monitor the pressure distribution during the clamping process in real time to ensure that the cable is not damaged. When the pressure exceeds the preset value, the controller can automatically adjust the clamping force to avoid over-compressing the cable. This design realizes the closed-loop adaptive clamping pressure adjustment and also improves the accuracy and safety of detection. At the same time, on the premise of being able to detect the clamping pressure, the clamping assembly has the ability to perform a compressive strength test on the cable to be measured.

[0018] Furthermore, a first friction layer is laid on the arc-shaped kit, and the center of the first friction layer is fixedly connected to the arc-shaped groove.

[0019] The beneficial effects of the basic solution are as follows: 1. The addition of the first friction layer improves the friction between the arc-shaped kit and the cable surface, making the cable more stable during the clamping process and not easy to slide or shake. This helps to ensure the accuracy of the detection results and avoid errors caused by the change of the cable position.

[0020] 2. The first friction layer is usually made of soft and wear-resistant materials such as rubber or silica gel. When these materials come into contact with the cable surface, they can reduce the damage to the cable surface caused by friction and protect the integrity of the cable. This is particularly important for cables that need to be frequently detected and can extend their service life.

[0021] 3. Due to the certain elasticity and adaptability of the first friction layer, it can better fit the cable surfaces with different diameters and materials. This further enhances the adaptive ability of the multi-stage clamping assembly, making the device applicable to a wider range of cable detection and clamping requirements.

[0022] Furthermore, the multi-stage clamping assemblies also include a clamping motor close to the rear gear ring, the clamping motors are fixedly connected to the inner bottom wall of the annular shell and are parallel to the axial direction of the annular shell, the output shafts of the clamping motors are coaxially fixedly connected to a clutch shaft rotatably connected to the inner wall of the annular shell, the middle of the clutch shaft is fixedly connected to a clutch, the clutch shaft is coaxially fixedly connected to a front gear and a rear gear, and the front gear and the rear gear are respectively meshed with the outer periphery of the front gear ring and the rear gear ring;

[0023] The clutch comprises a clutch shaft driving end close to the rear gear and a clutch shaft driven end close to the front gear, the clutch shaft driving end is coaxially and vertically fixedly connected with a driving plate, the driving plate is provided with a plurality of radially arranged first ball grooves, the first ball grooves are equipped with first balls, the depth of the first ball grooves is greater than the radius of the first ball, the clutch shaft driven end is coaxially slidably matched with the center of the driving plate, the outer periphery of the clutch shaft driven end is provided with a plurality of axial second ball grooves, the outer periphery of the clutch shaft driven end is slidably sleeved with the driven plate, the driven plate is close to the The inner wall of the outer periphery of the driven end of the clutch shaft is provided with a plurality of third ball grooves corresponding to the second ball grooves, and a second ball is matched between the third ball groove and the second ball groove. A clutch spring is rotatably connected to the side of the driven plate away from the active plate, and the other end of the clutch spring is sleeved on the driven end of the clutch shaft and fixedly connected to the side wall of the front gear. The side wall of the driven plate close to the active plate is provided with a plurality of fourth ball grooves corresponding to the first ball grooves, and the depth of the fourth ball groove is less than the radius of the first ball, and the clamping motor is connected to the controller signal.

[0024] The beneficial effects of the basic solution are: 1. The design of the clutch makes the clamping process more stable and reliable. Through the cooperation of the active disc, the driven disc and the ball, the clutch can accurately control the transmission of the clamping force to avoid over-clamping or under-clamping. At the same time, the introduction of the clutch provides a multi-stage screw-in effect. When the torque of the current gear reaches the limit, the clutch automatically falls off so that the clamping motor can continue to screw into the clamping rod to adapt to the smaller diameter of the cable to be tested.

[0025] 2. The cooperation between the front gear and the rear gear and the clutch shaft enables the clamping assembly to achieve precise adjustment of the cable. By adjusting the rotation angle and speed of the clutch shaft, the moving distance and clamping force of the front and rear gear rings can be accurately controlled to adapt to cables of different specifications and materials. This design greatly improves the applicability and flexibility of the device.

[0026] 3. Through the precise control of the clutch and the smooth operation of the clamping motor, the multi-stage clamping assembly can avoid excessive pressure or damage to the cable. At the same time, the buffering effect of the clutch spring further protects the integrity of the cable and improves the safety of the detection process.

[0027] Furthermore, a second friction layer is laid on the side walls of the driven plate and the driving plate, and the thickness of the second friction layer is less than half of the depth of the fourth ball groove.

[0028] The beneficial effects of the basic solution are as follows: 1. The addition of the second friction layer increases the friction force between the driven disc and the driving disc, making the clutch more stable and reliable during engagement. This helps to ensure the accurate transmission of the precession torque and avoid the situation of insufficient clamping caused by clutch slippage.

[0029] 2. The second friction layer is usually made of wear-resistant and soft materials such as rubber, plastic or special friction materials. When these materials come into contact with other components of the clutch, they can reduce wear and friction noise and extend the service life of the clutch. At the same time, since the thickness of the second friction layer is less than half of the depth of the fourth ball groove, it ensures that it will not interfere with the normal engagement and disengagement movement of the balls, thus ensuring the smooth operation of the clutch.

[0030] 3. The addition of the second friction layer enhances the adaptability of the clutch, enabling it to maintain stable performance under different temperature, humidity and load conditions. This is particularly important for the application of cable detection in different environments, ensuring the stability and reliability of the clamping assembly.

[0031] Furthermore, horizontal sliders are fixedly connected to the bottom of the annular shell. Horizontal sliding grooves are formed in the top wall of the workbench. The horizontal sliding grooves are located below the darkroom. Horizontal sliding rails are installed on the inner bottom wall of the horizontal sliding grooves. The horizontal sliders are all in sliding fit with the horizontal sliding rails. Rack bars that are parallel to each other and staggered up and down are fixedly connected to the side walls of the horizontal sliders facing the darkroom. A pulling motor perpendicular to the rack bars is fixedly connected to the middle bottom wall of the horizontal sliding groove. A pulling gear is coaxially fixedly connected to the output shaft of the pulling motor. The pulling gear is located between the rack bars and meshes with the upper and lower rack bars respectively. The pulling motor is in signal connection with the controller.

[0032] The beneficial effects of the basic solution are as follows: 1. The sliding fit between the horizontal sliders and the horizontal sliding rails enables the annular shell and its clamping assembly to move flexibly along the horizontal sliding grooves. Driven by the pulling motor, the tensile property of the cable to be tested can be tested, thus improving the overall functional level of the detection device.

[0033] 2. This design enables the annular shell to move freely in the horizontal direction and can adapt to cables of different lengths and specifications by adjusting the rotation direction and distance of the pulling motor. This flexibility enables the device to meet a wider range of cable detection requirements.

[0034] 3. The horizontal sliding grooves are located below the darkroom, making full use of the space resources of the workbench. At the same time, the compact design of the horizontal sliders and the horizontal sliding rails makes the entire device structure more compact, reduces the floor area and improves the space utilization rate of the entire device.

[0035] Furthermore, the roller assembly includes a first electric push rod and a second electric push rod symmetrically and fixedly connected to the outer side wall of the darkroom. The first electric push rod and the second electric push rod face in opposite directions. A pull rod is hinged to the output end of each of the first electric push rods. A roller arm is hinged to the end of each pull rod. One end of the roller arm close to the first electric push rod is hinged to the side wall of the darkroom. Forks are formed at the ends of the roller arms, and a roller shaft is vertically rotatably connected in each fork. A first roller is fixedly sleeved on the roller shaft. The first electric push rod is signal-connected to the controller.

[0036] The beneficial effects of the basic solution are as follows: 1. Through the symmetrical design of the first electric push rod and the second electric push rod and their hinged connection with the roller arms, the roller assembly can provide stable support during the cable propulsion process. This support helps prevent the cable from shifting or twisting during movement, thus ensuring the stability of the cable position and improving the detection accuracy.

[0037] 2. The fork design at the end of the roller arm and the vertical rotatable connection of the roller shaft enable the first roller to flexibly adapt to the cable propulsion direction. When the cable is being pushed, the clamping assembly is released, and the roller can roll smoothly and can fix the cable to a certain extent to maintain, reducing friction and resistance, thereby improving the smoothness of cable propulsion and facilitating subsequent re-clamping.

[0038] 3. The design of the roller assembly enables the entire detection device to better adapt to cables of different specifications and lengths. Whether it is a slender cable or a thick cable, the roller assembly can provide stable support through the clamping driven by the electric push rod, thereby enhancing the adaptability and flexibility of the device.

[0039] Furthermore, a pull bar is fixedly connected to the output end of each of the second electric push rods. Driving teeth are formed on both side walls of the pull bar. Power gears are meshed with both sides of the pull bar through the driving teeth. The power gears are rotatably connected to the corresponding side walls of the darkroom. Power arms are fixedly connected to the side walls of the power gears. A power shaft is rotatably connected between the ends of the corresponding power arms on both sides of the darkroom. A power motor is fixedly connected to the side of each end of the power arm far from the power shaft. The output shafts of the power motors are coaxially and fixedly connected to the corresponding power shafts. A second roller is fixedly sleeved on the power shaft. The power motor is signal-connected to the controller.

[0040] The beneficial effects of the basic solution are as follows: 1. Through the cooperation of the second electric push rod with the pull bar and the driving teeth, and the transmission of the power gear and the power arm, the clamping and propulsion of the cable are realized. This design enables the device to flexibly adjust the propulsion force according to the cable specifications and detection requirements, thereby improving the flexibility and accuracy of cable propulsion.

[0041] 2. The linkage design of the power arm with the power shaft and the second roller enables the device to handle cables of different lengths and diameters more proficiently. Whether the cable is slender or thick, the device can ensure the cable is smoothly and steadily advanced by adjusting the angle and force of the power arm. This not only improves the adaptability of cable handling but also significantly enhances the detection efficiency.

[0042] 3. Through the signal control of the controller, the operator can easily achieve remote control of the second electric push rod and related components. This automated control method greatly simplifies the operation process, reduces the labor intensity of the operator, and enables them to focus more on the detection task itself.

[0043] Furthermore, both axial sides of the first roller and the second roller are higher than the axial center.

[0044] The beneficial effects of the basic solution are as follows: 1. The design that both outer peripheral sides of the first roller and the second roller are higher than the center enables the rollers to better grip and guide the cable during rolling. This design not only enhances the stability of the cable during advancement, preventing it from swaying left and right or falling off, but also ensures that the cable can advance smoothly along the predetermined path.

[0045] 2. Due to the roller design, the contact area between the cable and the roller is more uniform, reducing the wear of the cable caused by excessive local stress during rolling. This helps reduce the risk of detection interruption or failure due to cable damage.

[0046] 3. This specially designed roller has good adaptability and can be applied to cables of different specifications and types. Whether it is a slender cable or a thick cable, the roller can provide stable gripping and guiding functions to ensure the smooth progress of the detection process.

[0047] Furthermore, the defect detection component includes several fixed platforms, which are all fixedly connected to the radial inner wall of the darkroom. Diffuse reflection layers are laid on the radial inner walls of the darkroom opposite to the fixed platforms. Supplementary lights, cameras, and markers are all fixedly connected to the fixed platforms, and the supplementary lights, cameras, and markers are all signal-connected to the controller.

[0048] The beneficial effects of the basic solution are as follows: 1. The layout of the front fixed platform and the rear fixed platform ensures that the cable can be detected comprehensively during advancement. The supplementary lights provide sufficient light, the cameras capture images of the cable surface, and the markers mark the detected defects. This series of operations together improve the detection accuracy and reliability.

[0049] 2. A diffuse reflection layer is laid on the inner wall of the darkroom in the radial direction opposite to the front fixing table and the rear fixing table, which can effectively enhance the uniformity of light illumination. The diffuse reflection layer can evenly scatter the light emitted by the supplementary light to the entire detection area, avoiding the appearance of light dead angles and shadow areas, thereby improving the quality of image capture and detection accuracy.

[0050] 3. The supplementary light, the camera, and the marker are all signal-connected to the controller, realizing the automation of detection. The operator only needs to set the detection parameters and start the detection process through the controller to achieve automatic detection and marking of defects. This not only greatly improves work efficiency but also reduces the influence of human factors on the detection results. Brief Description of the Drawings

Detailed implementation manners

[0060] The following is a further detailed description through specific implementation manners:

[0061] Embodiment 1

[0062] Basically as shown in the attached Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 shown: An electronic communication cable detection device includes a workbench 1, an insulation tester, and a dielectric loss tester. A darkroom 5 is installed on the workbench 1. Through openings are symmetrically formed on the axial side walls of the darkroom 5, and light-shielding curtains 4 are adhered to the through openings. A flaw detection assembly is welded inside the darkroom 5, and a roller assembly is welded on the outer side wall of the darkroom 5. Multistage clamping assemblies are symmetrically installed on the top of the workbench 1 on both sides of the darkroom 5. A controller 2 is welded on the workbench 1.

The flaw detection assembly, the roller assembly, the multistage clamping assembly, the insulation tester, and the dielectric loss tester are all signal-connected to the controller 2.

[0063] The flaw detection component is used to dynamically identify the diameter uniformity of the cable to be tested, as well as surface flaws such as surface bulges, pits, and scratches using real-time image acquisition technology and image recognition technology; the roller component is used to clamp the cable to be tested to limit shaking and drive the cable to be tested to move axially to achieve automated detection; the multi-stage clamping component is used to achieve adaptive and stable clamping of cables with different diameters through the principle of radial progressive clamping and clutch, and cooperate with an insulation tester and a dielectric loss tester to conduct tensile performance tests and compressive performance tests on the cable to be tested.

[0064] Each multi-stage clamping component includes an annular shell 13. Inside the annular shell 13, a front tooth ring 27 and a rear tooth ring 26 that are parallel to each other are coaxially and slidably sleeved.

On the side wall of the clamping column 29 close to the rear tooth ring 26, rod sliding grooves are opened. At one end of the clamping column 29 close to the center of the annular shell 13, arc-shaped kits 33 are welded. The arc-shaped kits 33 inside the same annular shell 13 can be spliced into an annular cylinder. On the side wall of the rear slider 14 close to the center of the rear tooth ring 26, connecting rods 31 are welded. The connecting rods 31 are all slidably fitted with the corresponding rod sliding grooves. At the ends of the connecting rods 31, clamping rods 30 are welded. The clamping rods 30 are all coaxially sleeved inside the corresponding clamping columns 29. The ends of the clamping rods 30 coincide with the circumferential vertices of the arc-shaped kits 33, and arc-shaped grooves 35 with a radian greater than that of the arc-shaped kits 33 are opened at the ends of the clamping rods 30. The arc-shaped grooves 35 inside the same annular shell 13 can be spliced into a cylinder. Pressure sensors are laid in both the arc-shaped kits 33 and the arc-shaped grooves 35. The pressure sensors are all signal-connected to the controller 2. A first friction layer 34 is laid on each arc-shaped kit 33. The center of the first friction layer 34 is bonded to the arc-shaped groove 35.

[0066] The multi-stage clamping assemblies also each include a clamping motor 23 near the rear tooth ring 26. The clamping motors 23 are each welded to the inner bottom wall of the annular housing 13 and are axially parallel to the annular housing 13. The output shafts of the clamping motors 23 are each coaxially welded with a clutch shaft 42 rotatably connected to the inner wall of the annular housing 13. A clutch 41 is installed in the middle of each clutch shaft 42. A front gear 21 and a rear gear 22 are welded to each clutch shaft 42. The front gear 21 and the rear gear 22 are respectively meshed with the outer circumferences of the front tooth ring 27 and the rear tooth ring 26.

[0067] Each clutch 41 includes a clutch shaft driving end 48 near the rear gear 22 and a clutch shaft driven end 47 near the front gear 21.

[0068] A horizontal slider 18 is welded to the bottom of each annular housing 13. A horizontal chute 19 is formed in the top wall of the workbench 1. The horizontal chute 19 is located below the darkroom 5. A horizontal slide rail 3 is installed on the inner bottom wall of the horizontal chute 19.

Rack bars 20 that are parallel to each other and staggered up and down are welded to the side walls of the horizontal sliders 18 facing the darkroom 5.

[0069] The specific implementation process is as follows: In cable quality testing, since there are multiple detection items, including electrical quality effect detection, appearance defect detection, anti-extraneous force detection, electromagnetic compatibility detection, insulation detection, and extreme environment tests, etc., if it is possible to integrate the detection items as much as possible on the premise of ensuring the stability of the cable to be tested and the detection accuracy of each item, it will help save instrument costs, reduce the complexity of the detection work, and improve the detection efficiency. However, ordinary cable clamping mechanisms can only fixedly clamp cables with a single diameter specification and thicker cables, and cannot stably clamp thinner cables. The traditional method is often to replace the clamping mechanism, which undoubtedly increases the complexity of cable detection operations, and it is also necessary for personnel to select a suitable specification of the clamping mechanism for replacement. Therefore, designing a clamping mechanism that can stably clamp cables of different thicknesses is crucial for improving the electronic communication cable detection device.

[0070] In the present invention, before using this device for cable detection, the cable needs to be passed through two annular shells 13 and the darkroom 5 first, and then the clamping motor 23 is turned on to clamp the cable. First, the controller 2 controls the clamping motor 23 to rotate the clutch shaft 42. At this time, the driving disk 49 and the driven disk 44 are in close contact, and the torque of the front gear 21 has not reached the limit of the clutch spring 43. The first ball 51 on the driving disk 49 is embedded in the corresponding fourth ball groove 52 on the driven disk 44. The torque from the clamping motor 23 at the active end 48 of the clutch shaft is transmitted to the driven end 47 of the clutch shaft through the first ball 51 and the second friction layer, causing the front gear 21 and the rear gear 22 on the clutch shaft 42 to rotate simultaneously, driving the front gear ring 27 and the rear gear ring 26 to rotate synchronously. The front gear ring 27 and the rear gear ring 26 located inside the annular shell 13 rotate, and respectively push the front slider 15 and the rear slider 14 to screw into the center of the annular shell 13 in the front chute and the rear chute through the spiral rack 28. Such a clamping method can improve the stability during the clamping process, and can make the outer circumference of the cable receive uniform force, reducing the possibility of the cable being damaged on the surface during clamping. The front slider 15 pushes the connecting block 32 and the clamping column 29 to gather, and the rear slider 14 pushes the connecting rod 31 and the clamping rod 30 to gather until the arc-shaped kit 33 and the arc-shaped groove 35 come into contact with the surface of the cable to be tested and firmly clamp the cable at the exact center of the annular shell 13, so that the cable to be tested being clamped is in a parallel straight line, which is conducive to obtaining the most real and accurate detection results.

[0071] As Figure 6As shown, when the cable to be tested is relatively thin and difficult to be clamped by the clamping column 29, at this time, the arc-shaped kit 33 has been closed to form a complete cylindrical shape, but the cable to be tested cannot be clamped. At this time, the clamping motor 23 is still rotating, and the fact that the arc-shaped kit 33 has been closed means that the torque of the front tooth ring 27 of the front slider 15 during precession has reached the limit and is difficult to rotate. The front gear 21 and the driven end 47 of the clutch shaft are also locked and stopped accordingly. At this time, since the driven disk 44 and the driven end 47 of the clutch shaft have reached the torque limit, when the driving disk 49 is still rotating, the first ball 51 disengages from the fourth ball groove 52, pushing the driven disk 44 to compress the clutch spring 43. And because there are axial second ball grooves 53 and third ball grooves 45 between the driven disk 44 and the driven end 47 of the clutch shaft, the second balls 46 therein enable the driven disk 44 to move linearly axially on the driven end 47 of the clutch shaft without affecting the torque conduction of the driven disk 44. The thickness of the second friction layer being less than half of the depth of the fourth ball groove 52 means that the first ball 51 will not be affected by the second friction layer when it disengages from the fourth ball groove 52. At this time, the driving disk 49 and the driving end 48 of the clutch shaft that have disengaged from the driven disk 44 are still rotating. The rear gear 22 continues to drive the rear tooth ring 26 to rotate, and the precession rear slider 14 causes the connecting rod 31 and the clamping rod 30 to close towards the center of the annular housing 13. The connecting rod 31 slides in the rod chute. At this time, the clamping column 29 remains stationary while the clamping rod 30 protrudes towards the center of the annular housing 13 at the center of the clamping column 29, lifting the first friction layer 34 and clamping the relatively thin cable to be tested. The arc-shaped groove 35 and the first friction layer 34 can better fit the surface of the cable to be tested, thereby broadening the specification range of the cables to be tested for clamping detection, providing stable clamping, reducing the possible shaking of the cable to be tested during the detection process, improving the accuracy of the test, and laying a structural foundation for pressurizing the clamping assembly to test the compressive resistance of the cable to be tested. During the subsequent pressurization test process, the arc-shaped kit 33 and the arc-shaped groove 35 that wrap around the outer circumference of the cable in a ring shape can apply pressure to the cable from multiple directions, ensuring the uniformity of the pressure during the pressurization test process and enhancing the reliability and comprehensiveness of the compressive resistance test results.

[0072] When releasing the clamping, the first ball 51 on the driving disk 49 fits with the fourth ball groove 52 again. The second friction layer enhances the friction to drive the driven end 47 of the clutch shaft to rotate in the reverse direction, and at the same time, it rotates and pushes the front slider 15 and the rear slider 14, and then disengages to reset the front slider 15 and the rear slider 14.

[0073] Since pressure sensors are laid in both the arc-shaped kit 33 and the arc-shaped groove 35, the clamping assembly can not only adaptively clamp the cable to be tested according to the diameter specification, but also automatically adjust the torque output by the clamping motor 23 according to the pressure data fed back by each pressure sensor to the controller 2, avoiding the cable to be tested shaking due to too loose clamping and damaging the surface of the cable to be tested due to too tight clamping.

[0074] And based on the pressure data feedback, the pressure data can also be preset. In cooperation with the insulation tester and the dielectric loss tester, the insulation and dielectric loss of the cable under test can be tested under the preset pressure environment, so as to evaluate the compressive resistance of the cable under test. In addition, as Figure 3 shown, the bottom of the annular shell 13 is fixed on the horizontal slider 18 that is slidably fitted on the horizontal slide rail 3. The horizontal slider 18 is vertically and fixedly connected to a horizontal rack 20 facing the center of the horizontal chute 19. Through the pulling gear 24 that meshes with the mutually vertically staggered racks 20, the pulling motor 25 can push the position of the horizontal slider 18 through forward and reverse rotation, so that the annular shells 13 on both sides of the dark room 5 approach each other to adjust the position or move away from each other to axially pull and clamp the cable under test. In cooperation with the insulation tester and the dielectric loss tester, the insulation and dielectric loss of the cable under test can be tested under a certain pulling force at the preset torque, and the tensile resistance test of the cable under test can be carried out. Thus, the two physical resistance tests are combined with the clamping assembly of multi-stage progressive clamping, and the test items are integrated in a single device, reducing the instrument requirements for the detection of electronic communication cables and improving the detection efficiency.

[0075] Embodiment 2

[0076] The difference from the above embodiment is that, as shown in the attached Figure 1 、 Figure 2 and Figure 4 shown: The roller assembly includes a first electric push rod 6 and a second electric push rod 7 symmetrically welded on the outer side wall of the dark room 5. The first electric push rod 6 and the second electric push rod 7 face in opposite directions. A pull rod is hinged to the output end of the first electric push rod 6, and a roller arm 16 is hinged to the end of the pull rod. One end of the roller arm 16 close to the first electric push rod 6 is hinged to the side wall of the dark room 5. The ends of the roller arm 16 are both bifurcated, and a roller shaft is vertically rotatably connected in the bifurcation. A first roller 17 is fixedly sleeved on the roller shaft. The first electric push rod 6 is signal-connected to the controller 2.

[0077] A pull bar 9 is welded to the output end of the second electric push rod 7. Push teeth are opened on both side walls of the pull bar 9. A power gear 8 is meshed with both sides of the pull bar 9 through the push teeth. The power gear 8 is rotatably connected to the corresponding side wall of the dark room 5. A power arm 10 is welded to the side wall of the power gear 8. A power shaft is rotatably connected between the ends of the corresponding power arms 10 on both sides of the dark room 5. A power motor 11 is welded to the side of the end of the power arm 10 away from the power shaft. The output shafts of the power motors 11 are coaxially welded to the corresponding power shafts. A second roller 12 is fixedly sleeved on the power shaft. The power motor 11 is signal-connected to the controller 2.

[0078] Both axial sides of the first roller 17 and the second roller 12 are higher than the axial center.

[0079] The specific implementation process is as follows: The main function of the roller assembly is to further stabilize the position of the cable under test being clamped and to achieve automatic advancement of the cable for detection. When the cable under test has been clamped by the clamping assembly, the first electric push rod 6 is activated to push the pull rod, causing the roller arm 16 to move around its hinge axis. The first roller 17 clamps the cable under test from both horizontal sides to achieve horizontally pushable clamping. The two sides of the outer periphery of the first roller 17 are higher than the center, allowing the cable under test to always remain at the initial clamping position of the first roller 17 without being affected by gravity, and enhancing the adhesion of the first roller 17 to the surface of the cable under test, thereby enhancing its clamping effect.

[0080] At the same time, the second electric push rod 7 on the other side of the darkroom 5 pulls the pull bar 9, and the power gears 8 engaged on both sides of the pull bar 9 rotate, causing the second rollers 12 located above and below the cable under test to close towards the middle to clamp the cable under test, ensuring that the cable under test always remains in its stable position.

[0081] When it is necessary to advance the cable under test, the clamping assembly slightly loosens the cable under test. At this time, the position of the cable under test will not change because it is clamped by the roller assembly. Then, the upper and lower power motors 11 drive the second rollers 12 to rotate, pulling the cable under test through the darkroom 5. Due to the clamping of the first roller 17 and the second roller 12, the axial position of the cable under test will not change. The clamping assembly clamps the cable under test again to detect the next section of the cable under test. The entire process is controlled by the controller 2 without the need for manual participation, realizing the automation of the detection work and reducing the uncertainties that may exist in the detection work.

[0082] Embodiment 3

[0083] The difference from the above embodiment is that as shown in Figure 1 、 Figure 3 and Figure 5 : The flaw detection assembly includes a number of fixed platforms 40, and the fixed platforms 40 are all welded to the radial inner wall of the darkroom 5. Diffuse reflection layers 36 are laid on the radial inner walls of the darkroom 5 opposite to the fixed platforms 40. Supplementary light lamps 39, cameras 38 and markers 37 are all welded on the fixed platforms 40, and the supplementary light lamps 39, cameras 38 and markers 37 are all connected to the controller 2 in a signal manner.

[0084] The specific implementation process is as follows: When the power electricity rotates the second roller 12 to push the cable to be tested, the cable passes through the darkroom 5 and is photographed by the camera 38. The image of the camera 38 is recognized by the controller 2 for possible surface defects on the cable, and the marker 37 is timely controlled to spray paint to mark the defect position, which is convenient for subsequent statistics of the defect type and quantity and research on the cause of the defect. The darkroom 5, the light-shielding curtain 4 and the supplementary light 39 are to prevent other lights in the detection room from affecting the shooting effect of the camera 38. At the same time, the supplementary light 39 can better illuminate the cable to be tested, and the light of the remaining supplementary lights 39 shines on the diffuse reflection layer 36 opposite to the front fixing table 40 and the rear fixing table 40, reducing specular reflection and avoiding strong reflection from forming light spots in the image of the camera 38 and affecting the shooting effect. By pushing the cable to be tested, it is possible to ensure that each section of the cable to be tested is accurately detected under the condition of reducing the arrangement of detection instruments, thereby improving the detection efficiency and reducing the equipment cost and labor cost of the detection work.
