Description
Technical Field
[0001] This utility model belongs to the field of cable processing, and in particular relates to a tensile testing device for cable processing. Background Technology
[0002] In the cable processing industry, tensile testing is a crucial step in evaluating cable performance, and its results directly affect the cable's safety and reliability. Traditional cable tensile testing equipment has several shortcomings in practical applications:
[0003] Conventional clamps often use a single clamping method, which can easily lead to insecure clamping for cables of different diameters and materials. Especially in high-strength tensile tests, the cable may slip out of the clamp due to uneven force, resulting in test interruption or distorted results.
[0004] Furthermore, if the cable is fixed solely by the friction of the clamping surface, it is prone to slippage when there is oil or wear on the cable surface, which can affect the test accuracy.
[0005] Therefore, a tensile testing device for cable processing is needed to solve the above problems. Utility Model Content
[0006] The purpose of this utility model embodiment is to provide a tensile testing device for cable processing to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A tensile testing device for cable processing includes a control frame, a drive component, a movable plate, a clamp, and a testing component. The clamp and the testing component are provided in pairs. The opposite sides of the two clamps are respectively connected to the control frame and the movable plate. The movable plate is slidably connected inside the control frame. The drive component is provided inside the control frame.
[0009] The clamp includes a fixed base, a rotating component, a fixed component, and a clamping component;
[0010] The fixed base includes a fixed shell, the rotating component includes a rotating tube, the rotating tube is connected to the fixed shell through a bearing, a worm gear and a drive plate are connected to the outside of the rotating tube, the worm gear meshes with a worm, the worm is rotatably connected inside the fixed shell, the drive plate has a plurality of drive holes, and a first gear is connected to the outside of the rotating tube;
[0011] The fixing component includes a rotating roller, which is rotatably connected inside the fixing shell. A second gear is connected to the outside of the rotating roller, and the first gear meshes with the second gear. A through hole is opened inside the rotating roller, and the through hole is located directly below the rotating tube.
[0012] The clamping component includes several clamping seats, each with anti-slip texture on its adjacent side, and a sliding rod connected to the lower surface of each clamping seat, the sliding rod being slidably connected within a drive hole.
[0013] In a further technical solution, the driving component consists of a motor and a lead screw. The lead screw is threadedly connected inside the movable plate and rotatably connected inside the control frame. The top end of the lead screw is connected to the motor, and the motor is fixedly connected to the top end of the control frame.
[0014] In a further technical solution, the upper surface of the fixed shell is provided with several through slots, and guide rods are connected to each of the several through slots.
[0015] In a further technical solution, one end of the worm gear is connected to a turntable, and the turntable is located outside the fixed housing.
[0016] In a further technical solution, both the first gear and the second gear are bevel gears, and both the first gear and the second gear are housed within a fixed housing.
[0017] In a further technical solution, the slide rod is slidably connected to the outside of the guide rod, and the slide rod is slidably connected to the inside of the through groove.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] This utility model features dual fixation to enhance stability. By employing a dual fixation method of "clamping + bending and winding," the connection strength between the cable and the clamp is significantly enhanced. The multiple clamping seats of the clamping component are tightly attached to the cable surface through anti-slip textures. At the same time, the rotating roller of the fixing component bends and winds the cable, further locking the cable through mechanical deformation. Even under high-strength tensile force, the cable is not easy to fall off, ensuring a stable and reliable testing process.
[0020] This utility model provides precise guidance to ensure concentricity of the clamping. The through groove of the fixed shell and the guide rod form a double guiding constraint on the slide rod, ensuring that the clamping seat always remains concentric during movement and avoiding uneven force on the cable due to clamping offset. At the same time, the coaxial design of the rotating tube and the rotating roller (the through hole is located directly below the rotating tube) ensures the consistency of the cable axis during bending and clamping, improving the accuracy of test data.
[0021] This invention is easy to operate and highly controllable. The turntable at one end of the worm gear allows for manual adjustment of the clamping force. Combined with the motor-screw structure of the drive component, the moving speed and tension of the movable plate can be precisely controlled. The detection component can monitor the tension data in real time, enabling visualization and quantitative analysis of the testing process, thus improving both operational convenience and testing accuracy.
[0022] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0030] like Figures 1-4 As shown, this utility model embodiment provides a tensile testing device for cable processing, including a control frame 1, a drive component 2, a movable plate 3, a clamp 4, and a testing component 5. The control frame 1 provides a sliding track for the movable plate 3. The motor of the drive component 2 drives the lead screw to rotate, so that the movable plate 3 moves smoothly along the control frame 1, thereby achieving uniform application of tensile force. The screw thread transmission has high precision and can accurately control the tensile force loading speed, such as 0.1mm / s-5mm / s, to meet the requirements of different testing standards.
[0031] Two clamps 4 and two test pieces 5 are provided. The two test pieces 5 are respectively installed on the control frame 1 and the movable plate 3. The tensile force at both ends of the cable is monitored in real time and the data is transmitted synchronously. By comparing and analyzing, the error caused by the difference in the fixing of the clamp 4 can be eliminated, and the reliability of the test results can be further improved.
[0032] The two clamps 4 are connected to the control frame 1 and the movable plate 3 respectively on opposite sides. The movable plate 3 is slidably connected inside the control frame 1. The control frame 1 is equipped with a drive component 2, which consists of a motor and a lead screw. The lead screw is threadedly connected inside the movable plate 3 and rotatably connected inside the control frame 1. The top end of the lead screw is connected to the motor, and the motor is fixedly connected to the top end of the control frame 1.
[0033] The clamp 4 includes a fixed base 41, a rotating component 42, a fixed component 43, and a clamping component 44;
[0034] The fixing base 41 includes a fixing shell 411, and the upper surface of the fixing shell 411 is provided with a plurality of through grooves 412, and a guide rod 413 is connected in each of the plurality of through grooves 412.
[0035] Rotating component 42 includes a rotating tube 421, which is connected to a fixed housing 411 via a bearing 422. A worm gear 423 and a drive plate 426 are connected to the outside of the rotating tube 421. The worm gear 423 meshes with a worm 424, which is rotatably connected inside the fixed housing 411. One end of the worm 424 is connected to a turntable 425. The drive plate 426 has several drive holes 427. The arc-shaped design of the drive holes 427 causes the sliding rod 442 to generate a radial contraction force during movement, ensuring… Multiple clamping seats 441 move closer or further apart simultaneously to avoid excessive force on a single point, which could damage the cable. A first gear 428 is connected to the outside of the rotating tube 421. Both the first gear 428 and the second gear 432 are bevel gears. Both the first gear 428 and the second gear 432 are located inside the fixed housing 411. The meshing of the first gear 428 and the second gear 432 converts the horizontal rotation of the rotating tube 421 into the vertical rotation of the rotating roller 431, ensuring that the cable bending direction is consistent with the clamping direction.
[0036] The fixing component 43 includes a rotating roller 431, which is rotatably connected to the fixing shell 411. A through hole 433 is provided in the rotating roller 431, which is located directly below the rotating tube 421.
[0037] The clamping component 44 includes several clamping seats 441, and each of the lower surfaces of the clamping seats 441 is connected to a slide rod 442. The slide rod 442 is slidably connected to the outside of the guide rod 413, the inside of the drive hole 427, and the inside of the through groove 412. The worm gear 424 of the rotating component 42 rotates to drive the worm wheel 423 to rotate, thereby driving the rotating tube 421 and the drive plate 426 to move synchronously, realizing the linkage between the opening and closing of the clamping seats 441 and the rotation of the rotating roller 431.
[0038] The device is self-adjusting and adaptable to various cable specifications. The worm gear 424-worm wheel 423 structure of the rotating component 42 drives the drive plate 426 to rotate, causing multiple slide bars 442 to move synchronously along the drive hole 427, thereby making the opening and closing distance of the clamping seat 441 adjustable. It can adapt to cables of different diameters, such as 0.5mm-20mm, without the need to replace the clamp 4, reducing the complexity of operation and equipment cost, and improving the versatility of the device.
[0039] In this embodiment, when the device needs to be used, one end of the cable is inserted into the rotating tube 421, so that the cable passes through the rotating tube 421 and moves to the through hole 433. Then the turntable 425 is rotated in the forward direction. The rotating turntable 425 drives the worm gear 424 to rotate. The rotating worm gear 424 drives the worm wheel 423 to rotate. The rotating worm wheel 423 drives the rotating tube 421 to rotate. The rotating tube 421 drives the drive plate 426 and the first gear 428 to rotate synchronously. The rotating first gear 428 drives the rotating roller 431 to rotate through the second gear 432. The rotating roller 431 bends the cable through the through hole 433. The bent cable is then wrapped around the outside of the rotating roller 431.
[0040] Simultaneously, the rotating drive plate 426 drives several arc-shaped drive holes 427 to rotate synchronously. The rotating drive holes 427 drive several slide rods 442 to move closer to each other. The close-to-each slide rods 442 slide outside the guide rod 413 and inside the through groove 412. The close-to-each slide rods 442 drive several clamping seats 441 to move closer to each other. The close-to-each clamping seats 441 clamp and fix the outer surface of the cable inside the rotating tube 421.
[0041] One end of the cable is double-fixed by the fixing part 43 and the clamp, so that the cable can be firmly connected to the clamp 4. When the cable is subjected to tensile testing, the cable is not easy to fall off the clamp 4 due to unstable fixing, so that the cable can be tested smoothly.
[0042] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.
[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
