Description

Technical Field

[0001] This utility model relates to the field of testing devices, specifically an external deformation testing device for cable production. Background Technology

[0002] As an important carrier of power transmission and communication, cables play a crucial role in various fields such as modern industry, energy, transportation, and construction. Their quality is directly related to the safe and stable operation of related facilities. Therefore, ensuring cable quality is of paramount importance. During the cable production process, external deformations such as twisting, flattening, and scratches may affect the insulation performance, electrical performance, and mechanical strength of the cable, and may even lead to cable failures during use and cause safety accidents. Accurate detection of external deformations during the cable production process is an important link in ensuring cable quality.

[0003] However, in the existing technology, the traditional external deformation detection device for cable production has obvious limitations. The cable is transported by a roller conveyor and flows continuously under the detection device to complete the external deformation detection. However, since the detection device is only fixed above the cable, there are significant blind spots in its detection range. It is impossible to conduct a comprehensive and thorough detection of the entire outer circumference of the cable, which makes it difficult to ensure the comprehensiveness and accuracy of the detection results. Utility Model Content

[0004] The purpose of this invention is to provide an external deformation detection device for cable production, so as to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An external deformation detection device for cable production includes a detection workbench. The upper end of the detection workbench is provided with a moving component for moving the detection device. The upper end of the moving component is provided with a support plate. The upper end of the support plate is provided with an adjustment component for adjusting the angle of the detection device. A first detection mechanism for detecting external deformation of the cable is provided on one side of the adjustment component. A second detection mechanism is provided on one side of the support plate.

[0007] Preferably, the moving component includes guide plates, the lower ends of which are fixedly installed on the upper part of the inspection workbench near both sides. Each of the two guide plates has a sliding groove inside, and a sliding block is slidably connected inside each of the two sliding grooves. A lead screw is rotatably connected inside one of the sliding blocks. The lead screw is rotatably sleeved inside the sliding groove of one of the guide plates. A servo motor is fixedly installed at one end of the lead screw, and the output shaft of the servo motor is drively connected to one end of the lead screw. A fixing plate is fixedly installed at one end of the servo motor, and one side of the fixing plate is fixedly installed at one end of one of the guide plates.

[0008] Preferably, the adjustment component includes an annular outer ring, the lower end of which is fixedly mounted with a support plate, and the bottom of the support plate is fixedly connected to the upper end of the sliding block at both ends.

[0009] Preferably, an annular tooth is fixedly installed on the inner wall of the annular outer ring, and a gear is meshed with the inner side of the annular tooth. A rotating rod is fixedly sleeved inside the gear. A first U-shaped bracket is rotatably sleeved on one end of the rotating rod. An electric motor is fixedly installed on one end of the rotating rod, and the output shaft of the electric motor is connected to one end of the rotating rod in a transmission manner.

[0010] Preferably, a second U-shaped bracket is fixedly installed on one side of the first U-shaped bracket, and the upper and lower ends of the first U-shaped bracket and the second U-shaped bracket are fixedly connected by multiple fixing rods. A sliding groove is provided at the upper part of the interior of both the first U-shaped bracket and the second U-shaped bracket, and the sliding groove is movably fitted on both sides of the annular outer ring.

[0011] Preferably, cards are fixedly connected to the upper sides of the interior of both the first U-shaped bracket and the second U-shaped bracket, with the upper ends of both cards contacting the inner wall of the annular outer ring. A first detection mechanism is fixedly installed on one upper side of the second U-shaped bracket.

[0012] The beneficial effects of this utility model are:

[0013] This invention utilizes a first detection mechanism that can be adjusted to an angle of less than 360 degrees to cover most of the outer area of ​​the cable. Combined with a second detection mechanism specifically for detecting the lower outer surface of the cable, the two mechanisms work together to achieve "no dead angle detection." This avoids missed detections caused by a fixed single angle and prevents significant blind spots in the detection range that would prevent comprehensive, no-dead-angle detection of the entire outer perimeter of the cable. It ensures that the detection mechanism can repeatedly scan within the effective range, increasing the probability of capturing subtle deformations and reducing the random errors of a single detection.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figure 1 As shown, an external deformation detection device for cable production includes a detection workbench 1. A moving component 2 for moving the detection device is provided at the upper end of the detection workbench 1. A support plate 3 is provided at the upper end of the moving component 2. An adjustment component 4 for adjusting the angle of the detection device is provided at the upper end of the support plate 3. A first detection mechanism 5 for detecting the external deformation of the cable is provided on one side of the adjustment component 4. A second detection mechanism 6 is provided on one side of the support plate 3.

[0023] In a specific embodiment, the first testing institution 5 and the second testing institution 6 are existing technologies, such as Cognex VisionPro system and FLIRA655sc.

[0024] Please refer to Figures 1 to 3 As shown, as a technical optimization of this utility model, the moving component 2 includes a guide plate 21. The lower end of the guide plate 21 is fixedly installed on the upper end of the detection workbench 1 near both sides. The interior of both guide plates 21 is provided with a sliding groove 22. The interior of both sliding grooves 22 is slidably connected with a sliding block 24. The interior of one of the sliding blocks 24 is rotatably connected with a lead screw 23. The lead screw 23 is rotatably sleeved inside the sliding groove 22 of one of the guide plates 21. A servo motor 26 is fixedly installed at one end of the lead screw 23. The output shaft of the servo motor 26 is connected to the lead screw 23. A fixing plate 25 is fixedly installed at one end of the servo motor 26. One side of the fixing plate 25 is fixedly installed at one end of one of the guide plates 21.

[0025] In a specific embodiment, when the first detection mechanism 5 and the second detection mechanism 6 move linearly along the cable, the servo motor 26 starts, the output shaft starts to rotate, and drives the lead screw 23 to rotate. The rotation of the lead screw 23 pushes the sliding block 24 to slide in the sliding groove 22. The linear movement of the sliding block 24 drives the support plate 3 to move, and further drives the first detection mechanism 5 and the second detection mechanism 6 to reciprocate, which can clamp the upper and lower sides of the cable.

[0026] Please refer to Figure 1 , Figures 3 to 5 As shown, as a technical optimization of this utility model, the adjusting component 4 includes an annular outer ring 41. A support plate 3 is fixedly installed at the lower end of the annular outer ring 41. The bottom of the support plate 3 is fixedly connected to the upper end of the sliding block 24 at both ends. An annular tooth 42 is fixedly installed on the inner wall of the annular outer ring 41. A gear 49 is meshed with the inner side of the annular tooth 42. A rotating rod 48 is fixedly sleeved inside the gear 49. A first U-shaped bracket 43 is rotatably sleeved at one end of the rotating rod 48. An electric motor 410 is fixedly installed at one end of the rotating rod 48. The output shaft of the electric motor 410 is connected to one end of the rotating rod 48 for transmission. A second U-shaped bracket 44 is fixedly installed on one side of the first U-shaped bracket 43, and the upper and lower ends of the first U-shaped bracket 43 and the second U-shaped bracket 44 are fixedly connected by multiple fixing rods 47. The upper part of the interior of the first U-shaped bracket 43 and the second U-shaped bracket 44 are provided with sliding grooves 45, which are movably fitted inside the two sides of the annular outer ring 41. Cards 46 are fixedly connected to the opposite sides of the upper part of the interior of the first U-shaped bracket 43 and the second U-shaped bracket 44, and the upper ends of the two cards 46 are in contact with the inner wall of the annular outer ring 41. A first detection mechanism 5 is fixedly installed on one upper side of the second U-shaped bracket 44.

[0027] In a specific embodiment, when the cable is conveyed and moved inside the annular outer ring 41, the electric motor 410 drives the rotating rod 48 to rotate, which in turn drives the gear 49 to rotate. The gear 49 rotates on the inner teeth of the annular gear 42. When the gear 49 rotates around the annular outer ring 41, the gear 49 can only rotate to both sides of the support plate 3 and rotates at an angle of less than 360 degrees. This further drives the first U-shaped bracket 43 and the second U-shaped bracket 44 to rotate around the annular outer ring 41. As a result, the slide groove 45 slides at an angle of less than 360 degrees on both sides of the annular outer ring 41. When the angle is adjusted by the adjustment component 4, the first detection mechanism 5 can adjust the outer side of the cable by less than 360 degrees to detect the external deformation of the cable. The second detection mechanism 6 can detect the lower part of the cable's exterior, thus achieving detection without blind spots.

[0028] In use, when the cable moves within the annular outer ring 41, the electric motor 410 drives the rotating rod 48 to rotate, which in turn drives the gear 49 to rotate. The gear 49 then rotates on the inner teeth of the annular gear 42. As the gear 49 rotates around the annular outer ring 41, it can only rotate to both sides of the support plate 3, performing a reciprocating angle of less than 360 degrees. This further drives the first U-shaped bracket 43 and the second U-shaped bracket 44 to rotate around the annular outer ring 41. Consequently, the sliding groove 45 slides reciprocally in a circle on both sides of the annular outer ring 41, with the angle adjusted by the adjusting component 4. During dynamic adjustment, the first detection mechanism 5 can adjust the outer side of the cable by less than 360 degrees to detect the external deformation of the cable. The second detection mechanism 6 can detect the lower part of the cable's outer side, thus achieving detection without blind spots. When the first detection mechanism 5 and the second detection mechanism 6 move linearly along the cable, the servo motor 26 starts, the output shaft starts to rotate, driving the lead screw 23 to rotate. The rotation of the lead screw 23 pushes the sliding block 24 to slide in the sliding groove 22. The linear movement of the sliding block 24 drives the support plate 3 to move, further driving the first detection mechanism 5 and the second detection mechanism 6 to reciprocate, which can clamp the upper and lower parts of the cable's outer side.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
