Description

Technical Field

[0001] This application relates to the field of testing equipment, and in particular to a testing device for high-speed cables. Background Technology

[0002] In the new materials industry, in order to adapt to the rapid development of information technology, new materials for high-speed cables have been designed and are increasingly widely used in fields such as communications and electronics. However, in actual use, high-speed cables need to withstand various mechanical stresses and environmental factors, and their quality and performance are directly related to the stability and reliability of the entire system.

[0003] Existing cable testing technologies have several shortcomings when testing high-speed cables. For example, current testing devices cannot dynamically and accurately measure the diameter change of cables under different stress states, nor can they perform in-depth testing of the cable's insulation layer and other structures. Furthermore, existing clamping mechanisms are prone to damaging high-speed cables, affecting the accuracy of test results, and are also unable to meet the testing requirements of high-speed cables of different specifications.

[0004] Therefore, a testing device for high-speed cables is proposed.

[0005] Therefore, developing a device that can precisely control traction force, accurately detect changes in cable diameter, reliably clamp high-speed cables, and is applicable to testing various cable specifications is of great practical significance. Summary of the Invention

[0006] The purpose of this application is to solve the technical problem that existing cable testing devices cannot detect changes in cable diameter during traction force testing. Compared with the prior art, this application provides a testing device for high-speed cables, including a frame. The frame is provided with a traction mechanism for providing traction force to both ends of the cable to be tested. The traction mechanism includes two sets of oppositely arranged slides, and the top of each slide is fixed with a clamping mechanism for clamping the ends of the cable to be tested.

[0007] A diameter detection mechanism is fixed on the frame via an XZ-axis linear module. The diameter detection mechanism includes a bracket three fixed on the output end of the XZ-axis linear module. A C-shaped open ring is rotatably connected to one side of the bracket three. The C-shaped open ring has two sets of symmetrically arranged through-slide grooves. A clamping plate is slidably connected in each through-slide groove. A tensioning slide groove is provided on the clamping plate. A connecting column that cooperates with the tensioning slide groove is provided in the through-slide groove. A tensioning spring is also clamped between the connecting column and the tensioning slide groove. Two sets of symmetrically arranged displacement sensors are also symmetrically fixed on one side of the outer wall of the C-shaped open ring. A target plate that cooperates with the displacement sensor is fixed on the side of the two sets of clamping plates that are far apart.

[0008] Both sets of plates have detection ports on opposite sides, and telescopic blades are also slidably connected inside the plates;

[0009] The support frame three is equipped with a gear set for driving the rotation of the C-shaped open ring.

[0010] Furthermore, a blade is fixed at one end of the telescopic blade plate, and the blade is set on one side of the detection port; a spring plate is fixed at the other end of the telescopic blade plate.

[0011] The spring plate has the elastic force to drive the two sets of telescopic blades away from each other. The two sets of telescopic blades have a magnetic attraction force to each other when energized. The tension spring has the elastic force to drive the two sets of clamping plates closer to each other. The clamping plate is also provided with an inlet bevel on the side near the opening of the C-shaped opening ring.

[0012] Furthermore, a C-shaped open slide rail and a C-shaped open external gear are fixed on the C-shaped open ring. The bracket three is provided with an annular open slide groove that matches the C-shaped open slide rail. The output gear of the gear set meshes with the C-shaped open external gear, and the drive gear of the gear set is driven by a motor.

[0013] Furthermore, the traction mechanism includes two sets of brackets symmetrically fixed on the frame. Between the two sets of brackets, there are two sets of symmetrically arranged double-ended lead screws. A nut seat that cooperates with the double-ended lead screws is fixed on the slide. A traction motor is also fixed on one side of the bracket. The output end of the traction motor is connected to the double-ended lead screws through a reduction mechanism.

[0014] Furthermore, the clamping mechanism includes a bracket two fixed on the slide table, a protective cover fixed inside the bracket two, two sets of symmetrically arranged deflection seats inside the protective cover, a rotating shaft one fixed on the side of the two sets of deflection seats that are far apart, and a bearing seat one that cooperates with the rotating shaft one on the protective cover.

[0015] Two sets of deflection seats are rotatably connected by a vortex-shaped variable diameter wheel and an auxiliary wheel. The auxiliary wheel is equipped with a drive mechanism, which is used to drive the vortex-shaped variable diameter wheel and the auxiliary wheel to rotate relative to each other. The drive mechanism is also used to drive the deflection seats to rotate around the axis of rotation shaft one.

[0016] Furthermore, the drive mechanism includes a drive motor and a main gear. Both ends of the auxiliary wheel are fixed with a second rotating shaft. The deflection seat is provided with a second bearing seat corresponding to the second rotating shaft. The drive motor is fixed on one side of the deflection seat. The output end of the drive motor is fixedly connected to the second rotating shaft. The second rotating shaft is also provided with a spline shaft. The main gear is provided with a spline groove that mates with the spline shaft. A return spring is fixed between the main gear and the auxiliary wheel. An electromagnetic ring is fixed on the side of the main gear away from the auxiliary wheel.

[0017] The deflection seat is provided with a buffer groove at the end away from the bearing seat 2. A buffer slider is slidably connected in the buffer groove. A buffer spring is also fixed between the buffer slider and the buffer groove. Rotary shaft 3 is fixed at both ends of the vortex variable diameter wheel. Rotary shaft 3 is rotatably connected in the buffer slider. A secondary gear that meshes with the main gear is also fixed on the rotary shaft 3.

[0018] The end of the rotating shaft three is also fixed with a guide wheel. The protective cover is provided with a guide groove one that cooperates with the guide wheel. On the side of the protective cover away from the guide groove one, there is also a guide groove two and an arc-shaped rack. The arc-shaped rack cooperates with the main gear.

[0019] Furthermore, the return spring has a pulling force that drives the main gear closer to the auxiliary wheel. When the return spring is in a free state, the main gear is close to the auxiliary wheel and separates from the arc rack and disengages. When the electromagnetic ring is energized, it has a magnetic attraction force on the deflection seat. At this time, the main gear moves away from the auxiliary wheel and remains engaged with the arc rack.

[0020] The buffer spring has the elastic force to drive the buffer slider to move down closer to the first rotating shaft. When the buffer slider moves to its maximum stroke away from the first rotating shaft in the buffer groove, the auxiliary gear and the main gear are disengaged.

[0021] Furthermore, the guide groove is a variable diameter arc groove structure. The center of the guide groove is located on the axis of the bearing seat, and the upper half of its arc radius is equal to the distance between the axis of the guide wheel and the rotating shaft. The lower half of the guide groove's arc radius gradually decreases, and the maximum difference in change is equal to the maximum stroke of the buffer slider in the deflection seat.

[0022] The center of guide groove two is located on the axis of bearing housing one, and the arc radius of guide groove two is equal to the distance between the axes of rotating shaft two and rotating shaft one.

[0023] Furthermore, the two sets of vortex-type variable diameter wheels rotate relative to each other when clamping the cable, and the direction of rotation is the direction in which the outer diameter increases from small to large;

[0024] The outer side of the vortex-shaped variable diameter wheel is also equipped with a rubber edging.

[0025] Furthermore, the auxiliary wheel is heavier than the vortex-shaped variable diameter wheel, and the auxiliary wheel has a V-shaped groove inside.

[0026] Compared to existing technologies, the advantages of this application are:

[0027] This invention, through the proposed diameter detection mechanism, utilizes the coordinated operation of a tension spring, a clamping plate, a displacement sensor, and a target plate to measure the diameter change of a cable during the stretching process. Simultaneously, the rotation function of the C-shaped open ring and the telescopic blade not only allow for omnidirectional detection of the cable diameter but also enable the inspection of the cable's internal structure, such as the insulation layer. This provides more comprehensive data support for cable quality assessment, adapts to the testing needs of high-speed cables of different specifications, and exhibits wide applicability and good versatility.

[0048] The embodiments will be described clearly and completely with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application.

[0049] For examples, please refer to Figure 1 - Figure 13 The purpose of this invention is to provide a testing device for high-speed cables, which can record the diameter deformation of the cable while performing a traction force test on the cable to be tested, thereby testing the outer insulation of the cable under traction force and ensuring the insulation safety of the cable during use.

[0050] like Figure 1 As shown, it includes a frame 1, which serves as the basic support structure for the entire device and provides a stable platform for the installation and operation of other components.

[0051] Please see Figure 1 and Figure 7The frame 1 is equipped with a traction mechanism 2 for providing traction force to both ends of the cable 4 to be tested. The traction mechanism 2 includes two sets of oppositely arranged slides 24. The top of each slide 24 is fixed with a clamping mechanism 3 for clamping the ends of the cable 4 to be tested. Specifically, the traction mechanism 2 also includes two sets of brackets 21 symmetrically fixed on the frame 1. Two sets of symmetrically arranged double-ended lead screws 23 rotate between the two sets of brackets 21. Nut seats 241 that cooperate with the double-ended lead screws 23 are fixed on the slides 24. A traction motor 22 is also fixed on one side of the bracket 21. The output end of the traction motor 22 is connected to the double-ended lead screw 23 through a reduction mechanism 25.

[0052] When the traction motor 22 starts, it drives the double-ended lead screw 23 to rotate through the reduction mechanism 25. Since the nut seat 241 is fixedly connected to the slide table 24 and the nut seat 241 cooperates with the double-ended lead screw 23, the two sets of slide tables 24 move relative to each other or in opposite directions, providing a stable and precisely controllable traction force for the cable 4 to be tested.

[0053] Please see Figure 2 - Figure 6 A diameter detection mechanism 6 is fixed on the frame 1 via an XZ-axis linear module 5. The diameter detection mechanism 6 includes a bracket 61 fixed on the output end of the XZ-axis linear module 5. A C-shaped open ring 62 is rotatably connected to one side of the bracket 61. The C-shaped open ring 62 has two sets of symmetrically arranged through-slide grooves 623. A clamping plate 64 is slidably connected in each through-slide groove 623. A tensioning slide groove 641 is provided on the clamping plate 64. A connecting post 624 that cooperates with the tensioning slide groove 641 is provided in the through-slide groove 623. A tensioning spring 625 is also clamped between the connecting post 624 and the tensioning slide groove 641. Two sets of symmetrically arranged displacement sensors 63 are also symmetrically fixed on one side of the outer wall of the C-shaped open ring 62. A target plate 65 that cooperates with the displacement sensor 63 is fixed on the side of the two sets of clamping plates 64 that are far apart.

[0054] The XZ-axis linear module 5 can adjust the position of the diameter detection mechanism 6 in space to adapt to the testing needs of cables with different positions and diameters. When the cable passes through the C-shaped open ring 62, under the action of the tension spring 625, the two sets of clamping plates 64 will be tightly attached to the cable surface. At this time, the initial diameter data of the cable can be recorded using the feedback data from the displacement sensor 63 and the target plate 65. As the diameter of the cable changes during the stretching process, due to the cable's own mass, the diameter change point may not appear in the middle of the cable. The XZ-axis linear module 5 can drive the diameter detection mechanism 6 to clamp onto the cable and move it horizontally. The change data fed back by the displacement sensor 63 can be used to locate the diameter change point of the cable. During the subsequent continuous traction process, the clamping plate 64 will slide in the through groove 623 following the diameter change at the diameter change point, thereby driving the target plate 65 to move. The displacement sensor 63 can accurately measure the change in cable diameter by detecting the displacement change of the target plate 65.

[0055] The C-shaped open ring 62 is also fixed with a C-shaped open slide rail 621 and a C-shaped open external gear 622. The bracket 61 is provided with an annular open groove 612 that matches the C-shaped open slide rail 621. The output gear of the gear set 611 meshes with the C-shaped open external gear 622. The drive gear of the gear set 611 is driven by a motor. When the motor drives the gear set 611 to rotate, it drives the C-shaped open external gear 622 to rotate through gear meshing, thereby causing the C-shaped open ring 62 to rotate around its central axis. During the rotation of the C-shaped open ring 62, the cooperation between the C-shaped open slide rail 621 and the annular open groove 612 ensures the stability of the rotation. This allows for rotational diameter data acquisition at the diameter change point, comprehensively collecting the diameter change.

[0056] Each of the two sets of clamping plates 64 has a detection port 642 on one side facing each other. To reduce the friction between the detection port 642 and the cable surface, the detection port 642 is smoothly arranged to facilitate translation when it comes into contact with the outer wall of the cable. A telescopic blade plate 66 is also slidably connected inside the clamping plate 64. One end of the telescopic blade plate 66 is fixed with a blade edge 661, which is located on one side of the detection port 642. The other end of the telescopic blade plate 66 is fixed with a spring plate 662. Specifically, the spring plate 662 has an elastic force that drives the two sets of telescopic blade plates 66 away from each other. The two sets of telescopic blade plates 66 have a magnetic attraction force that attracts each other when energized. The tension spring 625 has an elastic force that drives the two sets of clamping plates 64 to come closer together. The clamping plate 64 also has an inlet bevel 643 on the side near the opening of the C-shaped open ring 62. The inlet bevel 643 facilitates the cable to smoothly enter the C-shaped open ring 62 and be clamped by the clamping plate 64.

[0057] When it is necessary to detect changes in the diameter of the internal wire harness of a cable, the control circuit can energize the two sets of telescopic blades 66. Under the action of magnetic attraction, the telescopic blades 66 extend and are higher than the plane of the detection port 642. At this time, the blade 661 is used to engage the insulation layer of the cable. At the same time, the tension spring 625 provides the elastic force for the blade 661 to cut into the insulation layer. With the rotation of the C-shaped open ring 62, the insulation layer of the cable is circumferentially cut. Since the two ends of the cable are under tension at this time, after the insulation layer is circumferentially cut, the insulation layer loses the tension and retracts, thus exposing the wire harness layer. At this time, the telescopic blades 66 retract, and the detection port 642 is used to further detect the internal structure of the cable. When this operation is not required, the elastic force of the spring plate 662 causes the telescopic blades 66 to retract, avoiding unnecessary damage to the cable.

[0058] Please see Figure 8 - Figure 13 The clamping mechanism 3 includes a bracket 31 fixed on the slide table 24. A protective cover 32 is fixed inside the bracket 31. Two sets of symmetrically arranged deflector seats 35 are provided inside the protective cover 32. A rotating shaft 351 is fixed on the side of the two sets of deflector seats 35 that are far apart from each other. A bearing seat 322 that cooperates with the rotating shaft 351 is provided on the protective cover 32. A vortex diameter reducing wheel 33 and an auxiliary wheel 34 are rotatably connected between the two sets of deflector seats 35. A V-groove 344 is provided inside the auxiliary wheel 34, which helps to better stabilize cables of different diameters and provide reliable clamping force. A drive mechanism is provided on the auxiliary wheel 34. The drive mechanism is used to drive the vortex diameter reducing wheel 33 and the auxiliary wheel 34 to rotate relative to each other. The drive mechanism is also used to drive the deflector seats 35 to rotate around the axis of the rotating shaft 351.

[0059] The drive mechanism includes a drive motor 37 and a main gear 343. Both ends of the auxiliary wheel 34 are fixed with a second rotating shaft 341. The deflection seat 35 is provided with a second bearing seat 353 corresponding to the second rotating shaft 341. The drive motor 37 is fixed on one side of the deflection seat 35. The output end of the drive motor 37 is fixedly connected to the second rotating shaft 341. The second rotating shaft 341 is also provided with a spline shaft 3411. The main gear 343 is provided with a spline groove 3431 that mates with the spline shaft 3411. A return spring 342 is fixed between the main gear 343 and the auxiliary wheel 34. An electromagnetic ring 3432 is fixed on the side of the main gear 343 away from the auxiliary wheel 34.

[0060] The deflector 35 has a buffer groove 352 at the end away from the bearing seat 353. A buffer slider 36 is slidably connected in the buffer groove 352. A buffer spring 361 is also fixed between the buffer slider 36 and the buffer groove 352. Both ends of the vortex variable diameter wheel 33 are fixed with a rotating shaft 331. The rotating shaft 331 is rotatably connected in the buffer slider 36. A secondary gear 332 that meshes with the main gear 343 is also fixed on the rotating shaft 331. A guide wheel 3311 is also fixed at the end of the rotating shaft 331. The protective cover 32 has a guide groove 321 that cooperates with the guide wheel 3311. The protective cover 32 also has a guide groove 323 and an arc rack 324 on the side away from the guide groove 321. The arc rack 324 cooperates with the main gear 343.

[0061] The return spring 342 has a pulling force that drives the main gear 343 to approach the auxiliary wheel 34. When the return spring 342 is in a free state, the main gear 343 approaches the auxiliary wheel 34 and separates from the arc rack 324 and disengages. When the electromagnetic ring 3432 is energized, it has a magnetic attraction force on the deflection seat 35. At this time, the main gear 343 moves away from the auxiliary wheel 34 and remains engaged with the arc rack 324.

[0062] The buffer spring 361 has the elastic force to drive the buffer slider 36 downward toward the rotating shaft 351. When the buffer slider 36 moves to its maximum stroke away from the rotating shaft 351 within the buffer groove 352, the auxiliary gear 332 and the main gear 343 are disengaged. The guide groove 321 is a variable diameter arc groove structure. Specifically, the center of the guide groove 321 is located on the axis of the bearing seat 322, and the radius of its upper arc is equal to the distance between the axis of the guide wheel 3311 and the rotating shaft 351. The radius of the lower arc of the guide groove 321 gradually decreases, and the maximum difference is equal to the maximum stroke of the buffer slider 36 within the deflection seat 35. The center of the guide groove 323 is located on the axis of the bearing seat 322, and the radius of the guide groove 323 is equal to the distance between the axis of the rotating shaft 341 and the rotating shaft 351.

[0063] When it is necessary to clamp the cable, the drive motor 37 starts and drives the auxiliary wheel 34 to rotate through the rotating shaft 341. At the same time, the meshing of the main gear 343 and the secondary gear 332 drives the vortex diameter reducing wheel 33 and the auxiliary wheel 34 to rotate relative to each other. The relative distance between the vortex diameter reducing wheel 33 and the auxiliary wheel 34 is adjusted to match the diameter of the cable to be clamped, and the end of the cable is initially clamped. With the special structure of the vortex diameter reducing wheel 33 and the rubber edging 333, it can better adapt to the clamping requirements of different specifications of cables without damaging the cable.

[0064] To prevent the cable from detaching between the vortex reducer wheel 33 and the auxiliary wheel 34, the vortex reducer wheel 33 and the auxiliary wheel 34 need to be driven to rotate around the rotation axis 351, so that the end of the cable is wound around the auxiliary wheel 34. The friction of the wound part is used to further improve the stable clamping force. Specifically, when the vortex reducer wheel 33 continues to rotate after clamping the cable, as the outer diameter of the vortex reducer wheel 33 in contact with the cable gradually increases, it will lift the vortex reducer wheel 33 and the buffer slider 36 to move upward to the maximum displacement value in the buffer groove 352. At this time, the secondary gear 332 moves upward and disengages from the main gear 343, and at the same time, the electromagnetic ring 3432 is energized. Specifically, a contact switch can be set at the top of the buffer groove 352 to energize the electromagnetic ring 3432. The conditions are determined by the contact switch. At this time, the main gear 343 overcomes the tension of the return spring 342 and displaces, and meshes with the arc rack 324. During the rotation of the main gear 343, it drives the deflection seat 35 to rotate around the axis of the rotation shaft 351, thereby realizing the cable winding operation. During this process, the guide wheel 3311 slides in the guide groove 321. When it slides to the lower end of the guide groove 321, the arc radius of the lower half of the guide groove 321 gradually decreases, and the maximum difference is equal to the maximum stroke of the buffer slider 36 in the deflection seat 35. At this time, the guide groove 321 will gradually squeeze the vortex diameter reducing wheel 33 and bring the vortex diameter reducing wheel 33 closer to the auxiliary wheel 34, so that the vortex diameter reducing wheel 33 and the auxiliary wheel 34 further clamp the end of the cable.

[0065] When the guide wheel 3311 moves to the lower end of the guide groove 321, on the one hand, the contact switch disconnects the energization of the electromagnetic ring 3432, causing the main gear 343 to reset and disengage from the arc rack 324. On the other hand, the guide groove 321 squeezes the guide wheel 3311, causing the auxiliary gear 332 to move down and re-engage with the main gear 343. At this time, the main gear 343 flips, increasing the gap between the drive vortex diameter reducer wheel 33 and the auxiliary wheel 34, thus releasing the clamping of the cable end. At the same time, since the weight of the auxiliary wheel 34 is greater than that of the vortex diameter reducer wheel 33, under the action of gravity, the drive vortex diameter reducer wheel 33 and the auxiliary wheel 34 rotate in the opposite direction around the rotation axis 351, realizing the state of releasing the clamping and resetting.

[0066] The specific testing process is as follows:

[0067] I. Installation and debugging of the testing equipment:

[0068] 1. Rack installation: Select a level, solid ground with sufficient load-bearing capacity as the installation base, and place the rack 1 stably; use a level to check the levelness of the rack 1, and adjust the anchor bolts at the bottom of the rack 1 to ensure that the rack 1 is in a level state, with the error controlled within the design range (±0.1°), so as to ensure the stability of subsequent component installation and operation.

[0073] 4. Traction Mechanism Debugging: Connect the power supply to the traction motor 22 and conduct a no-load test run; set different running speeds and strokes through the controller, observe the movement of the slide table 24, and check whether it is stable and accurate, and whether there are any abnormal phenomena such as jamming or abnormal noise; use the displacement sensor to accurately measure the displacement of the slide table 24, compare it with the set value, and if there is a deviation, make corresponding adjustments and calibrations to ensure that the displacement accuracy of the slide table 24 meets the design requirements and the error does not exceed ±0.1mm.

The error should be controlled within the design range, with the horizontal error not exceeding ±0.1° and the vertical error not exceeding ±0.05°.

[0076] 2. Diameter detection component installation: Install bracket 3 61 on the output end of XZ axis linear module 5, ensuring a firm connection; rotatably connect C-type open ring 62 to one side of bracket 3 61, ensuring that C-type open ring 62 can rotate flexibly through the cooperation of C-type open slide rail 621 and annular open slide groove 612; install components such as clamping plate 64, connecting column 624, tension spring 625, displacement sensor 63 and target plate 65, and check whether the installation of each component is correct and firm, and whether the sliding of clamping plate 64 in through slide groove 623 is smooth.

[0077] 3. Diameter Detection Mechanism Debugging: Connect the power supply to the XZ axis linear module 5 and displacement sensor 63 for trial operation; control the movement of the XZ axis linear module 5 in the X and Z axis directions through the controller to check its motion accuracy and stability; use a standard diameter cable model for simulation detection, pass the cable model through the C-shaped open ring 62, and observe whether the reading of the displacement sensor 63 accurately reflects the diameter of the cable model. If there is a deviation, make corresponding adjustments and calibrations to ensure that the diameter detection accuracy meets the design requirements and the diameter measurement error does not exceed ±0.01mm.

[0078] IV. Installation and Debugging of Clamping Mechanism:

[0079] 1. Installation of bracket and protective cover: Fix bracket 2 31 on slide table 24 to ensure that the installation is firm; install protective cover 32 inside bracket 2 31 and tighten it with bolts to ensure the protective and stable performance of protective cover 32.

[0080] 2. Internal Component Installation: Install the deflection seat 35, rotating shaft one 351, bearing seat one 322, vortex reducing wheel 33, auxiliary wheel 34, drive mechanism, and other components. Install rotating shaft two 341 and rotating shaft three 331 onto their respective bearing seats to ensure smooth rotation. Install the main gear 343, auxiliary gear 332, electromagnetic ring 3432, buffer slider 36, buffer spring 361, guide wheel 3311, and other components. Check that each component is installed correctly and securely, and that the gears mesh well without any jamming.

[0081] 3. Clamping Mechanism Debugging: Connect the power supply to the drive motor 37 and the electromagnetic ring 3432 for trial operation; control the forward and reverse rotation and speed of the drive motor 37 through the controller, observe the relative rotation of the vortex diameter reducing wheel 33 and the auxiliary wheel 34, and check whether it can clamp and release the cable normally; control the energization and de-energization of the electromagnetic ring 3432, observe the meshing and disengagement of the main gear 343 and the arc-shaped rack 324, and whether the angle adjustment of the deflection seat 35 is accurate and flexible. Use cable models of different diameters to conduct simulated clamping tests to check the adaptability of the clamping mechanism 3 to different specifications of cables and the stability of the clamping force. If there are any problems, make corresponding adjustments and optimizations.

[0082] V. Cable Testing Procedure:

[0083] 1. Initial state check: Before clamping the cable, check the initial state of the clamping mechanism 3 to ensure that the vortex diameter reducing wheel 33 and the auxiliary wheel 34 are in the right position, the main gear 343 and the secondary gear 332 are in the meshing state, and the buffer slider 36 is in the initial position under the action of the buffer spring 361.

[0084] 2. Cable placement: Place one end of the high-speed cable 4 to be tested between the vortex diameter reducing wheel 33 and the auxiliary wheel 34 of the clamping mechanism 3 on one side. Note that the cable should be kept as horizontal and centered as possible.

[0085] 3. Initial cable clamping: Start the drive motor 37, which drives the auxiliary wheel 34 to rotate via the rotating shaft 341. Under the meshing action of the main gear 343 and the secondary gear 332, the vortex variable diameter wheel 33 and the auxiliary wheel 34 rotate relative to each other. As the rotation continues, the vortex variable diameter wheel 33 gradually approaches the cable. Utilizing its special vortex structure and rubber edging 333, it works together with the auxiliary wheel 34 to clamp the cable, ensuring that the cable is firmly clamped and will not be damaged by excessive compression.

[0086] 4. Wire winding clamping: When the electromagnetic ring 3432 is energized, it generates a magnetic attraction force, causing the main gear 343 to move away from the auxiliary wheel 34 and maintain meshing with the arc-shaped rack 324. The drive motor 37 continues to rotate, and through the meshing of the main gear 343 and the arc-shaped rack 324, it drives the deflection seat 35 to rotate around the axis of the rotation shaft 351, thereby realizing the wire winding clamping action;

[0087] Place the other end of the cable on the clamping mechanism 3 on the other side in the same way, and perform initial clamping and winding clamping to ensure that the clamping state of both ends of the cable is consistent.

[0088] VI. Preparation for Diameter Inspection:

[0089] 1. Position adjustment: Control the XZ axis linear module 5 through the controller to move it in the X and Z axis directions, and adjust the diameter detection mechanism 6 to the part of the cable where the diameter needs to be detected; ensure that the center of the C-type open ring 62 is approximately coincident with the center of the cable, and the error is controlled within the design range (±0.5mm).

[0090] 2. Plate Adhesion: Under the action of the tension spring 625, the two sets of plates 64 will adhere tightly to the cable surface. Observe the adhesion of the plates 64 to ensure good contact between the plates 64 and the cable surface, without gaps or looseness. At this time, the displacement sensor 63 and the target plate 65 are in the initial working state, and the initial displacement reading is recorded.

[0091] VII. Tensile testing and diameter inspection:

[0092] 1. Tensile test start: Start the traction motor 22, which drives the double-headed screw 23 to rotate through the reduction mechanism 25, so that the two sets of slides 24 move relative to each other and apply tensile force to the cable 4 to be tested; according to the test requirements, set the running speed and tensile force of the traction motor 22 through the controller. Generally, start with a lower speed and a smaller tensile force, and gradually increase to the tensile force required for the test.

[0093] 2. Real-time Diameter Detection: During the stretching process, the diameter of the cable changes with the stress. This change in cable diameter causes the clamping plate 64 to slide within the through groove 623, thereby moving the target plate 65. The displacement sensor 63 detects the displacement change of the target plate 65 in real time and transmits the data to the control system. The control system processes and analyzes the displacement data, calculates the diameter change of the cable at different stretching stages, and displays it on the display screen in real time.

[0094] 3. Optional Multi-Angle Diameter Detection: If multi-angle diameter detection of the cable is required, during the stretching process, the drive gear of the motor-driven gear set 611 rotates, causing the C-shaped open ring 62 to rotate around its central axis. During rotation, cable diameter data at different angles is continuously recorded to obtain more comprehensive information on cable diameter changes.

[0095] 4. Insulation layer testing optional: If it is necessary to test the internal structure of the cable, such as the insulation layer, when the cable is stretched to a certain extent or reaches a specific test stage, the two sets of telescopic blades 66 are energized through the control circuit. Under the action of magnetic attraction, the telescopic blades 66 extend, using the blades 661 to cut or puncture the cable's insulation layer. Simultaneously, other testing equipment, such as an insulation resistance tester, can be used to test the internal structure of the cable and obtain relevant performance data.

[0096] VIII. Test Completion and Data Processing:

[0097] 1. Test stop: When the cable reaches the predetermined tensile force or breaks, the traction motor 22 stops running, and the tensile test ends.

[0098] 2. Cable release: Control drive motor 37 to reverse, causing the vortex diameter reducer wheel 33 and auxiliary wheel 34 to rotate in opposite directions, releasing the cable; at the same time, disconnect the power supply to the electromagnetic ring 3432, causing the main gear 343 to separate from the arc rack 324.

[0099] 3. Data Processing and Analysis: Data recorded during the testing process, including tensile force, displacement, and diameter changes, are organized and analyzed. Based on relevant standards and requirements, performance indicators such as tensile strength, elongation at break, and diameter change rate of the cable are calculated. The test results are compared with expected standards to determine whether the cable is qualified.

[0100] 4. Report Generation: Based on the data processing and analysis results, a detailed test report will be generated, including test items, test conditions, test results, and conclusions. The report should be clear, accurate, and complete to provide a basis for cable quality assessment and improvement.

[0101] This invention, through the proposed diameter detection mechanism 6, utilizes the coordinated operation of tension spring 625, clamping plate 64, displacement sensor 63, and target plate 65 to accurately measure the diameter change of the cable during the stretching process in real time. Simultaneously, the rotation function of the C-shaped open ring 62 and the telescopic blade 66 not only allow for omnidirectional detection of the cable diameter but also enable the inspection of the cable's internal structure, such as the insulation layer, providing more comprehensive data support for cable quality assessment. Furthermore, the relative rotation of the vortex diameter-changing wheel 33 and auxiliary wheel 34 in the clamping mechanism 3, along with the winding clamping, combined with the rubber edging 333 and V-groove 344, reliably clamps high-speed cables of different specifications without damaging them, ensuring clamping stability during testing and improving the reliability of test results.

[0102] The testing device of the present invention, through various adjustable structures such as the diameter-changing function of the vortex diameter-changing wheel 33, the angle adjustment function of the clamping mechanism 3, and the position adjustment function of the diameter detection mechanism 6, can adapt to the testing needs of high-speed cables of different specifications, and has wide applicability and good versatility.

[0103] The above are merely the best implementation methods adopted in this application in light of current practical needs, but the scope of protection of this application is not limited thereto.
