Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically to a testing device for cable production. Background Technology

[0002] Cables are used to transmit electricity, data, and signals, as well as to connect various devices and systems. Therefore, their reliability and safety are of paramount importance. Cable toughness testing can ensure that they will not be damaged by stress during long-term use, thereby reducing potential failures and hazards.

[0003] Publication No. CN221445705U discloses a cable toughness testing device. The device involves adjusting the distance between two support platforms to make them equidistant from the bending frame. The bending frame is then lowered to its lowest point. One end of the cable sample to be tested is passed through the conductor channel on either the left or right support platform. During this process, the cable sample also passes through the opening of the bending frame until it extends a certain distance from the conductor channel on the other side. Next, the bending frame is moved upwards to a designated position. During this process, the bending wheel gradually hooks the middle portion of the cable sample upwards, causing it to bend. At this point, the bent portion of the cable has been tested, and the operator can observe whether there are any abnormalities. The toughness of the cable sample can then be evaluated based on the feedback information from the bent portion. However, this patent still has the following problems in practical use: By adjusting the distance between the two support platforms to make the distance between the two platforms and the bending frame equal, the bending frame is then lowered to its lowest point. One end of the cable sample to be tested is passed through the conductor channel on the left or right support platform. During this process, the cable sample will also pass through the opening of the bending frame until it extends a certain distance from the conductor channel on the other side. Next, the bending frame is moved up to the designated position. During this process, the bending wheel will gradually hook the middle part of the cable sample upwards to bend it. At this point, the bent part of the cable has been tested, and the staff can observe whether there are any abnormalities in the bent part of the cable. Then, the toughness of the cable sample can be evaluated based on the feedback information from the bent part of the cable. However, the cable size varies. Although the above device can evaluate the toughness of the cable sample based on the feedback information from the bent part of the cable, when testing cables of different sizes, the guide wheel cannot compress larger or smaller cables.

[0004] A testing device for cable production is proposed to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a testing device for cable production, which solves the problem mentioned in the background art. Currently, the device adjusts the distance between two support platforms to make them equal to the distance between the two platforms and the bending frame. Then, the bending frame is lowered to its lowest point, and one end of the cable sample to be tested passes through the conductor channel on the left or right support platform. During this process, the cable sample also passes through the opening of the bending frame until it extends a certain distance from the conductor channel on the other side. Next, the bending frame is moved to a designated position. During this process, the bending wheel gradually hooks the middle part of the cable sample upwards, causing it to bend. At this point, the bent portion of the cable has been tested, and the operator can observe whether there are any abnormalities in the bent portion. The toughness of the cable sample can then be evaluated based on the feedback information from the bent portion. However, while the above device can evaluate the toughness of the cable sample based on the feedback information from the bent portion, it cannot effectively compress cables of different sizes when testing cables of varying sizes, as the guide wheel cannot properly clamp larger or smaller cables.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a testing device for cable production, comprising a base, wherein fixed blocks are symmetrically arranged on both sides of the top surface of the base; A threaded rod is connected through the inside of the fixing block. A scale is provided on both sides of the surface of the base. A positioning frame is fixedly installed in the middle of the top surface of the base. A screw is connected through the middle of the top surface of the positioning frame. A moving groove is symmetrically opened on both sides of the top surface of the base. A moving block is slidably connected inside the moving groove. A support platform is fixedly connected to the top surface of the moving block. A threaded groove is opened inside the support platform. The threaded groove is threadedly connected to the threaded rod. Also includes: The support platform has symmetrically formed grooves inside, and a lifting component is installed inside the grooves; The lifting assembly includes a fixing frame that is fixedly connected to the groove; An electric push rod is connected through the middle of the interior of the fixed frame.

[0007] Preferably, a sliding box is connected through the side surface of the electric push rod away from the fixed frame. The sliding box has symmetrically opened sliding grooves inside. A slider is slidably connected inside the sliding grooves. A sliding plate is fixedly connected to the bottom surface of the slider.

[0008] Preferably, a limiting groove is formed on the surface of the sliding plate, a limiting rod is slidably connected inside the limiting groove, a top rod is fixedly connected to the back of the limiting rod, and the top rod is connected through the sliding plate and the sliding box.

[0009] Preferably, a top plate is fixedly connected to the top surface of the top rod, and sliding blocks are fixedly connected to both sides of the top plate.

[0010] Preferably, sliding grooves are symmetrically provided on both sides of the groove, and the sliding grooves are slidably connected to the sliding block.

[0011] Preferably, a cable guide wheel is fixedly connected to the top surface of the top plate, and the cable guide wheel is slidably connected to the groove.

[0012] Preferably, a bearing seat is rotatably connected to the bottom surface of the screw, a pressure plate is fixedly connected to the bottom surface of the bearing seat, a bending wheel is provided below the pressure plate, and the two sides of the bending wheel are rotatably connected to the positioning frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This cable production testing device, by setting up a lifting component, allows the height of the cable guide wheel to be adjusted according to the size of the cable, thereby achieving the function of pressing cables of different sizes and thus testing the cables. The specific details are as follows: 1. By setting up a lifting assembly, when cable bending detection is required, the distance between the support platforms on both sides of the base and the positioning frame is made equal by the action of a scale, thereby ensuring that the bending angle of the cable on the two support platforms is consistent. Simultaneously, based on the cable size, the electric push rod is activated by a control switch, causing its output end to extend. This extension allows the sliding plate to slide inside the sliding box. The movement of the sliding plate causes the movement of the limiting groove, which in turn allows the limiting rod to slide adaptively within the limiting groove. When the sliding rod reaches the top of the limiting groove, it causes the top rod to rise. The rise of the top rod causes the top plate to rise, which in turn causes the guide wheel to rise. At the same time, when the limiting rod slides to the bottom of the limiting groove, it causes the top rod to fall. The fall of the top rod causes the top plate to fall, which in turn causes the guide wheel to fall. This achieves the function of height adjustment of multiple guide wheels. All lifting components are controlled by control switches to ensure that the lifting components rise, fall and stop at the same time. 2. By setting up a positioning frame, screw, bearing seat, and pressure plate, after the cable passes through the cable guide wheel and bending wheel, the screw is manually rotated. The screw and positioning frame are connected by a through thread, which allows the screw to descend during rotation. At the same time, the screw and bearing seat are rotatably connected, so the screw does not drive the bearing seat to rotate when rotating. However, when the screw descends, it drives the bearing seat to descend. The descent of the bearing seat drives the pressure plate to descend, thus allowing the pressure plate to gently press the cable on the bending wheel, thereby preventing the cable from shifting during movement.

[0014] 3. By setting up a threaded rod, a scale, a movable groove, a movable block, a support platform, and a threaded groove, when it is necessary to move the support platforms on both sides to a suitable position, the threaded rod is manually rotated. The rotation of the threaded rod drives the support platform to move. At the same time, the support platform is fixedly connected to the movable block, and the movable block is slidably connected to the movable groove. Through the cooperation between the movable block and the movable groove, the support platform can be limited, so that the support platform can move with the rotation of the threaded rod. At the same time, the scale ensures that the distance between the support platform and the positioning frame is equal, thereby ensuring that the bending angle of the cables on the two support platforms is consistent.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-7 This utility model provides a technical solution: a testing device for cable production, including a base 1, with fixed blocks 2 symmetrically arranged on both sides of the top surface of the base 1; a threaded rod 3 is connected through the inside of the fixed blocks 2; scales 4 are provided on both sides of the surface of the base 1; a positioning frame 5 is fixedly installed in the middle of the top surface of the base 1; a screw 6 is connected through the middle of the top surface of the positioning frame 5; moving grooves 7 are symmetrically opened on both sides of the top surface of the base 1; moving blocks 8 are slidably connected inside the moving grooves 7; a support platform 9 is fixedly connected to the top surface of the moving blocks 8; a threaded groove 10 is opened inside the support platform 9, and the threaded groove 10 is threadedly connected to the threaded rod 3; it also includes: grooves 11 symmetrically opened inside the support platform 9; a lifting assembly 12 is provided inside the grooves 11; wherein, the lifting assembly 12 includes a fixed frame 1201 fixedly connected to the grooves 11; wherein, an electric push rod 1202 is connected through the middle of the fixed frame 1201, such as Figure 1-7 As shown, by setting up the lifting component 12, the height of the cable guide wheel 16 can be adjusted according to the size of the cable, thereby achieving the clamping of cables of different sizes and enabling cable testing. By setting up the threaded rod 3, scale 4, moving groove 7, moving block 8, bearing platform 9 and threaded groove 10, when it is necessary to move the bearing platforms 9 on both sides to the appropriate position, the threaded rod 3 can be manually rotated, so that the rotation of the threaded rod 3 can drive the bearing platform 9 to move. At the same time, the bearing platform 9 is fixedly connected to the moving block 8, and the moving block 8 is slidably connected to the moving groove 7. Through the cooperation between the moving block 8 and the moving groove 7, the bearing platform 9 can be limited, so that the bearing platform 9 can move with the rotation of the threaded rod 3. At the same time, the scale 4 ensures that the distance between the bearing platform 9 and the positioning frame 5 is equal, thereby ensuring that the bending angle of the cable on the two bearing platforms 9 is consistent, which facilitates the staff to evaluate the toughness of the cable sample and ensures the accuracy of the evaluation results.

[0019] A sliding box 1203 is connected through the side surface of the electric push rod 1202 away from the fixed frame 1201. The sliding box 1203 has symmetrically opened sliding grooves 1204 inside. A slider 1205 is slidably connected inside the sliding grooves 1204. A sliding plate 1206 is fixedly connected to the bottom surface of the slider 1205.

[0020] A limiting groove 1207 is formed on the surface of the slide plate 1206. A limiting rod 1208 is slidably connected inside the limiting groove 1207. A top rod 1209 is fixedly connected to the back of the limiting rod 1208. The top rod 1209 is connected through the slide plate 1206 and the sliding box 1203. A top plate 13 is fixedly connected to the top surface of the top rod 1209. Sliding blocks 14 are fixedly connected to both sides of the top plate 13. Sliding grooves 15 are symmetrically formed on both sides of the groove 11. The sliding grooves 15 are slidably connected to the sliding blocks 14. A cable guide wheel 16 is fixedly connected to the top surface of the top plate 13. The cable guide wheel 16 is slidably connected to the groove 11. Figure 4 , 5 As shown, the electric push rod 1202 is activated by a control switch, causing its output end to extend. This extension allows the slide plate 1206 to slide inside the sliding box 1203. The movement of the slide plate 1206 causes the limiting groove 1207 to move. This movement of the limiting groove 1207 causes the limiting rod 1208 to slide adaptively within the limiting groove 1207. Simultaneously, when the limiting rod 1208 slides to the top of the limiting groove 1207, it causes the top rod 1209 to rise. This rise of the top rod 1209... The lifting mechanism can drive the top plate 13 to rise, which in turn drives the guide wheel 16 to rise. At the same time, when the limit rod 1208 slides to the bottom of the limit groove 1207, it will drive the top rod 1209 to fall. The falling of the top rod 1209 will drive the top plate 13 to fall, which in turn drives the guide wheel 16 to fall, thereby achieving the function of height adjustment of multiple guide wheels 16. At the same time, multiple lifting components 12 are controlled by control switches to ensure that the lifting components 12 rise, fall and stop at the same time.

[0021] A bearing seat 17 is rotatably connected to the bottom surface of the screw 6. A pressure plate 18 is fixedly connected to the bottom surface of the bearing seat 17. A bending wheel 19 is located below the pressure plate 18. The two sides of the bending wheel 19 are rotatably connected to the positioning frame 5. Figure 6 , 7 As shown, by setting up a positioning frame 5, a screw 6, a bearing seat 17, and a pressure plate 18, after the cable passes through the cable guide wheel 16 and the bending wheel 19, the screw 6 is manually rotated. The screw 6 and the positioning frame 5 are connected by a through thread, which allows the screw 6 to descend when rotating. At the same time, the screw 6 and the bearing seat 17 are rotatably connected, so that the rotation of the screw 6 will not drive the rotation of the bearing seat 17. However, when the screw 6 descends, it can drive the bearing seat 17 to descend. The descent of the bearing seat 17 can drive the descent of the pressure plate 18, so that the pressure plate 18 can gently press the cable on the bending wheel 19, thereby preventing the cable from shifting during movement.

[0022] Working principle: Before using this cable production testing device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 7 As shown, firstly, by setting up the lifting component 12, when it is necessary to perform cable bending detection, the scale 4 is used to ensure that the distance between the bearing platforms 9 on both sides of the base 1 and the positioning frame 5 is equal, thereby ensuring that the bending angle of the cable on the two bearing platforms 9 is consistent. At the same time, according to the size of the cable, the electric push rod 1202 is activated by the control switch, causing the output end of the electric push rod 1202 to extend. Through the extension of the output end of the electric push rod 1202, the sliding plate 1206 can be moved inside the sliding box 1203. The movement of the sliding plate 1206 causes the movement of the limiting groove 1207. Through the movement of the limiting groove 1207, the limiting rod 1208 slides adaptively inside the limiting groove 1207. At the same time, the limiting rod... When 1208 slides to the top of the limiting groove 1207, it causes the top rod 1209 to rise. The rise of the top rod 1209 causes the top plate 13 to rise. The rise of the top plate 13 causes the guide wheel 16 to rise. At the same time, when the limiting rod 1208 is at the bottom of the limiting groove 1207, it causes the top rod 1209 to fall. The fall of the top rod 1209 causes the top plate 13 to fall. The fall of the top plate 13 causes the guide wheel 16 to fall, thereby achieving the function of height adjustment of multiple guide wheels 16. At the same time, multiple lifting components 12 are controlled by control switches to ensure that the lifting components 12 rise, fall and stop at the same time.

[0023] Secondly, by setting up the positioning frame 5, screw 6, bearing seat 17, and pressure plate 18, after the cable passes through the cable guide wheel 16 and bending wheel 19, the screw 6 is manually rotated. The screw 6 and the positioning frame 5 are connected by a through thread, which allows the screw 6 to descend when rotating. At the same time, the screw 6 and the bearing seat 17 are rotatably connected, so the screw 6 does not drive the bearing seat 17 to rotate when rotating. However, when the screw 6 descends, it can drive the bearing seat 17 to descend. The descent of the bearing seat 17 can drive the pressure plate 18 to descend, so that the pressure plate 18 can gently press the cable on the bending wheel 19, thereby preventing the cable from shifting during movement.

[0024] Finally, by setting up the threaded rod 3, scale 4, moving groove 7, moving block 8, support platform 9, and threaded groove 10, when it is necessary to move the support platforms 9 on both sides to a suitable position, the threaded rod 3 can be manually rotated to move the support platform 9. At the same time, the support platform 9 is fixedly connected to the moving block 8, and the moving block 8 is slidably connected to the moving groove 7. Through the cooperation between the moving block 8 and the moving groove 7, the support platform 9 can be limited, so that the support platform 9 can move with the rotation of the threaded rod 3. At the same time, through the function of the scale 4, it is ensured that the distance between the support platform 9 and the positioning frame 5 is equal, thereby ensuring that the bending angle of the cables on the two support platforms 9 is consistent.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
