Description

Technical Field

[0001] This utility model belongs to the field of burr removal technology, and in particular relates to a device for removing burrs from the surface of cables. Background Technology

[0002] During the cable manufacturing process, whether it is extrusion molding, conductor stranding or insulation coating, defects such as burrs, flash, and protrusions are easily generated on the cable surface. These defects not only damage the appearance integrity of the cable, but also pose serious hidden dangers for subsequent use.

[0003] Cable surface burr removal devices commonly employ a fixed grinding structure design. The core grinding components of these devices are typically fixed in place by rigid brackets. Their installation position, spacing, and relative distance to the cable axis are all preset to accommodate cables with specific outer diameters. In actual production, they usually only support a very small range of mechanical fine-tuning, making it difficult to cover the differences in outer diameters of cables of different specifications. When processing cables with outer diameters exceeding the fine-tuning range, either the grinding components cannot contact the burrs, resulting in incomplete removal, or the components excessively compress the cable surface, causing damage to the insulation layer. Effective adaptation is difficult to achieve. Due to the lack of a flexible pressure adjustment mechanism, existing fixed grinding structures cannot guarantee uniform contact between the grinding components and the outer walls of cables with different outer diameters. For cables with smaller outer diameters, there is a gap between the components and the cable surface, and some burrs cannot be ground. For cables with larger outer diameters, the grinding pressure applied by the components is too high, easily causing secondary damage such as scratches and dents on the cable surface, resulting in a decrease in product qualification rate. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a cable surface burr removal device, which has the advantages of easy adjustment and a wide range of cable outer diameters. It solves the problem that the grinding components with fixed structures in the prior art can only be adapted to cables with fixed outer diameters and have a low adaptation range.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A cable surface burr removal device includes a protective assembly. The protective assembly includes a support plate, and a circumferential groove is formed at the right end of the support plate. A rotating assembly is installed in the groove. The rotating assembly includes a sliding ring slidably mounted on the inner wall of the groove. A rotating ring is fixedly connected to the right end of the sliding ring. Several fixed plates are equidistantly mounted around the inner wall of the rotating ring. An adjusting assembly is installed at the end of each fixed plate near the axis of the rotating ring. The adjusting assembly includes a fixed cylinder fixed to the outer wall of the fixed plate. A movable cylinder is slidably mounted on the inner wall of the fixed cylinder. A movable rod is slidably mounted on the inner wall of the movable cylinder. A metal brush is fixedly connected to the end of the movable rod near the axis of the rotating ring. A spring is fixedly connected to the end of the movable rod away from the axis of the rotating ring. The other end of the spring is fixedly connected to the inner wall of the movable cylinder away from the axis of the rotating ring. The protective assembly also includes a protective box fixed to the outer wall of the support plate. The rotating assembly is located inside the protective box. Support assemblies are installed at the ends of the support plate and the protective box that are away from each other.

[0007] Furthermore, the protective assembly also includes a protective cover fixed to the left end of the support plate, an adjustment component located inside the protective cover, a slot is opened through the lower outer wall of the protective cover, an air vent is fixed inside the slot, and a vacuum cleaner is connected to the air outlet of the air vent through a pipe.

[0008] It is worth noting that the protective cover can enclose the adjustment components and metal brush, preventing cable burrs from flying during grinding and avoiding injury to operators. The air vent at the bottom of the protective cover is connected to the vacuum cleaner through a pipe, and the slot provides installation space for the air vent. When the vacuum cleaner is working, it can efficiently adsorb burrs inside the protective cover through the air vent, keeping the inside of the device and the working environment clean, while preventing burr accumulation from affecting the grinding effect of the metal brush.

[0009] Furthermore, several support rollers are rotatably mounted at the right edge of the bearing plate, equidistantly surrounding it, with the outer wall of the support rollers fitting against the outer wall of the rotating ring.

[0010] It is worth noting that by having the outer wall of the support roller adhere to the outer wall of the rotating ring, a stable support can be formed for the rotating ring in the circumferential direction, reducing the radial sway when the rotating ring rotates; ensuring that the rotating ring drives the metal brush to rotate evenly around the cable axis, avoiding incomplete grinding in some areas due to rotational deviation, and improving the uniformity and reliability of burr removal on the cable surface.

[0011] Furthermore, the support assembly includes a support frame fixed to one end edge of the protective box and the bearing plate that are far apart from each other. Electric cylinders are fixed to the inner edges of the upper and lower ends of the support frame, and support seats are fixed to the output ends of the electric cylinders.

[0012] It is worth noting that the support frame provides a fixed installation base for the electric cylinder. The output end of the electric cylinder can drive the support seat to move up and down, thereby adjusting the contact height between the support seat and the cable. The electric adjustment eliminates the need for manual disassembly and adjustment, making it convenient to operate and quick to adapt to cables of different outer diameters, ensuring that the support component always stably supports or clamps the cable.

[0013] Furthermore, the support assembly also includes pulleys that are rotatably mounted on the inner wall of the support base, with two support bases on one side corresponding to each other vertically.

[0014] It is worth noting that the pulleys can roll along with the cable, which greatly reduces the friction between the cable and the support, and avoids scratching the cable surface. The pulleys on the two support seats that correspond to each other can clamp and guide the cable from the top and bottom, ensuring that the cable is transported smoothly along the axis. The rotating metal brush can remove burrs from all directions.

[0015] Furthermore, the outer wall of the rotating ring is provided with a groove that surrounds the rotating ring, and a gear ring is fixedly connected in the groove. The rotating assembly also includes a servo motor fixedly connected to the right end of the support plate. A gear is fixedly connected to the output end of the servo motor, and the gear meshes with the gear ring. A dustproof plate is fixedly connected to the inner edge of the rotating ring.

[0016] It is worth noting that: through the meshing of the gear and the gear ring at the output end of the servo motor, the servo motor can drive the gear to drive the gear ring and the rotating ring to rotate synchronously when working. The speed is controllable and the rotation is stable, ensuring that the metal brush polishes the cable surface evenly. The dustproof plate on the inner wall of the rotating ring can prevent external dust from entering the rotating and adjusting components, avoiding dust from affecting the sliding or meshing of parts and extending the service life of the device.

[0017] Furthermore, a groove is provided through the outer wall of the fixed cylinder, and a screw hole is provided on the outer wall of the movable cylinder. A bolt is provided in the groove, and the bolt passes through the groove and is threaded onto the inner wall of the screw hole. The head of the bolt is pressed against the outer wall of the fixed cylinder.

[0018] It is worth noting that the groove on the outer wall of the fixed cylinder provides sliding space for the bolt. After loosening the bolt, the movable cylinder can slide along the inner wall of the fixed cylinder. Adjust the initial radial position of the metal brush, tighten the bolt so that its head is pressed against the outer wall of the fixed cylinder, and then lock the position of the movable cylinder.

[0019] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0020] This invention provides a mounting base for the rotating and adjusting components using a support plate. A groove on its right end allows the sliding ring to slide flexibly, thereby adjusting the position of the rotating ring and ensuring the metal brush is precisely aligned with the cable grinding area. A fixed plate on the inner wall of the rotating ring provides stable support for the adjusting component. The adjusting component achieves bidirectional adjustment through a multi-layered sliding structure of "fixed cylinder + movable cylinder + movable rod." The movable cylinder slides along the inner wall of the fixed cylinder to coarsely adjust the radial distance of the metal brush. The movable rod slides along the inner wall of the movable cylinder, and with the elastic buffer of the spring, the metal brush can adaptively conform to the surface of cables with different outer diameters, avoiding hard contact damage to the cable. This also significantly expands the device's adaptability range for cable outer diameters. The protective box encloses the rotating component, preventing burrs from splashing or external impurities from entering during grinding, protecting the internal components and ensuring stable operation.

Detailed Implementation

[0028] like Figures 1 to 5As shown, this utility model discloses a cable surface burr removal device, including a protective assembly. The protective assembly includes a support plate 102, and a circumferential groove 103 is formed at the right end of the support plate 102. A rotating assembly is installed in the groove 103, and the rotating assembly includes a sliding ring 301 slidably mounted on the inner wall of the groove 103. A rotating ring 302 is fixedly connected to the right end of the sliding ring 301. Several fixed plates 305 are fixedly connected to the inner wall of the rotating ring 302 at equal intervals around the perimeter. An adjusting assembly is installed at one end of each fixed plate 305 near the axis of the rotating ring 302. The adjusting assembly includes a fixed cylinder 40 fixedly connected to the outer wall of the fixed plate 305. 1. A movable cylinder 402 is slidably installed on the inner wall of the fixed cylinder 401. A movable rod 403 is slidably installed on the inner wall of the movable cylinder 402. A metal brush 405 is fixedly connected to one end of the movable rod 403 near the axis of the rotating ring 302. A spring 404 is fixedly connected to one end of the movable rod 403 away from the axis of the rotating ring 302. The other end of the spring 404 is fixedly connected to the inner wall of the movable cylinder 402 away from the axis of the rotating ring 302. The protective assembly also includes a protective box 101 fixedly connected to the outer wall of the bearing plate 102. The rotating assembly is located inside the protective box 101. Support assemblies are installed at the ends of the bearing plate 102 and the protective box 101 that are far apart from each other.

[0029] The support plate 102 provides a mounting base for the rotating and adjusting components. The slide groove 103 at its right end allows the sliding ring 301 to slide flexibly, thereby adjusting the position of the rotating ring 302 to ensure that the metal brush 405 is precisely aligned with the cable polishing area. The fixing plate 305 on the inner wall of the rotating ring 302 provides stable support for the adjusting component. The adjusting component achieves bidirectional adjustment through a multi-layer sliding structure of "fixed cylinder 401 + movable cylinder 402 + movable rod 403". The movable cylinder 402 can be used to coarsely adjust the metal brush 405 by sliding along the inner wall of the fixed cylinder 401. The radial distance, the sliding of the movable rod 403 along the inner wall of the movable cylinder 402, and the elastic buffer of the spring 404 allow the metal brush 405 to adaptively conform to the surface of cables with different outer diameters, avoiding hard contact damage to the cable, and at the same time greatly expanding the device's adaptability range to cable outer diameters. The protective box 101 encloses the rotating components, which can prevent burrs from flying or external impurities from entering during the grinding process, and protect the internal parts to ensure stable operation. The support components at both ends of the bearing plate 102 and the protective box 101 can assist in the smooth transport of the cable and ensure that the cable does not deviate during grinding.

[0030] Please see Figure 3The protective assembly also includes a protective cover 106 fixed to the left end of the support plate 102. The adjustment component is located inside the protective cover 106. A slot 107 is opened through the lower outer wall of the protective cover 106. An air vent 108 is fixed inside the slot 107. The air outlet of the air vent 108 is connected to a vacuum cleaner through a pipe. The protective cover 106 can enclose the adjustment component and the metal brush 405 to prevent cable burrs generated during grinding from flying and avoid injury to the operator. The air vent 108 at the lower end of the protective cover 106 is connected to the vacuum cleaner through a pipe. The slot 107 provides installation space for the air vent 108. When the vacuum cleaner is working, it can efficiently adsorb burrs inside the protective cover 106 through the air vent 108, keeping the inside of the device and the working environment clean, while preventing burr accumulation from affecting the grinding effect of the metal brush 405.

[0031] Several support rollers 104 are rotatably mounted at the right edge of the bearing plate 102, equidistantly surrounding it. The outer wall of the support rollers 104 is in contact with the outer wall of the rotating ring 302. By having the outer wall of the support rollers 104 in contact with the outer wall of the rotating ring 302, a stable support can be formed for the rotating ring 302 in the circumferential direction, reducing the radial sway when the rotating ring 302 rotates. This ensures that the rotating ring 302 drives the metal brush 405 to rotate evenly around the cable axis, avoiding incomplete grinding in some areas due to rotational deviation, and improving the uniformity and reliability of burr removal on the cable surface.

[0032] The support assembly includes a support frame 201 fixed to the edge of the protective box 101 and the bearing plate 102 at opposite ends. Electric cylinders 202 are fixed to the inner edges of the upper and lower ends of the support frame 201. Support seats 203 are fixed to the output ends of the electric cylinders 202. The support frame 201 provides a fixed installation base for the electric cylinders 202. The output ends of the electric cylinders 202 can drive the support seats 203 to move up and down, thereby adjusting the contact height between the support seats 203 and the cable. The electric adjustment eliminates the need for manual disassembly and adjustment, making it convenient to operate and quick to adapt to cables of different outer diameters, ensuring that the support assembly always stably supports or clamps the cable.

[0033] The support assembly also includes pulleys 204 rotatably mounted on the inner wall of the support base 203. The two support bases 203 on one side correspond to each other vertically. The pulleys 204 can roll along with the cable, greatly reducing the friction between the cable and the support base 203 and preventing the cable surface from being scratched. The pulleys 204 on the two support bases 203 that correspond to each other vertically can clamp and guide the cable from the top and bottom, ensuring that the cable is transported smoothly along the axial direction. Together with the rotating metal brush 405, it can achieve all-round burr removal.

[0034] Please see Figure 4The outer wall of the rotating ring 302 has a groove 303 that surrounds the rotating ring 302. A gear ring 304 is fixedly connected inside the groove 303. The rotating assembly also includes a servo motor 105 fixedly connected to the right end of the support plate 102. A gear 307 is fixedly connected to the output end of the servo motor 105. The gear 307 meshes with the gear ring 304. A dustproof plate 306 is fixedly connected to the inner edge of the rotating ring 302. When the servo motor 105 is working, it can drive the gear 307 to drive the gear ring 304 to rotate synchronously with the rotating ring 302. The speed is controllable and the rotation is stable, ensuring that the metal brush 405 polishes the cable surface evenly. The dustproof plate 306 on the inner wall of the rotating ring 302 can prevent external dust from entering the rotating assembly and the adjusting assembly, avoiding dust from affecting the sliding or meshing of parts and extending the service life of the device.

[0035] Please see Figure 5 The outer wall of the fixed cylinder 401 has a groove 407 extending through it, and the outer wall of the movable cylinder 402 has a screw hole 406. A bolt 408 is installed in the groove 407. The bolt 408 passes through the groove 407 and is threaded onto the inner wall of the screw hole 406. The head of the bolt 408 abuts against the outer wall of the fixed cylinder 401. The groove 407 on the outer wall of the fixed cylinder 401 provides sliding space for the bolt 408. After loosening the bolt 408, the movable cylinder 402 can slide along the inner wall of the fixed cylinder 401. Adjust the initial radial position of the metal brush 405, tighten the bolt 408 so that its head abuts against the outer wall of the fixed cylinder 401, and the position of the movable cylinder 402 can be locked.

[0036] Working Principle: Initial Support Adjustment: Based on the outer diameter of the cable to be processed, the electric cylinders 202 on the inner walls of the upper and lower ends of the support frame 201 in the support assembly are activated. Their output ends drive the support base 203 to move until the pulleys 204 on the inner wall of the support base 203 are in contact with the cable surface. The upper and lower corresponding support bases 203 clamp and guide the cable through the pulleys 204, which not only prevents the conveying from deviating but also reduces friction and avoids cable scratches.

[0037] Adjustment component debugging: Loosen the bolts 408 inside the groove 407 on the outer wall of the fixed cylinder 401, and push the movable cylinder 402 (the fixed cylinder 401 is fixed to the inner wall of the rotating ring 302 fixed plate 305) to slide along the fixed cylinder 401, and roughly adjust the distance between the metal brush 405 and the cable shaft; tighten the bolts 408 to lock the movable cylinder 402. At this time, the spring 404 at the end of the movable rod 403 pushes it to slide along the movable cylinder 402, so that the metal brush 405 adapts to the cable, preventing damage from hard contact, and adapting to cables of different outer diameters.

[0038] Rotary Grinding: The servo motor 105 at the right end of the support plate 102 is started, and its output gear 307 meshes with the gear ring 304 in the groove 303 on the outer wall of the rotating ring 302, driving the rotating ring 302 to rotate synchronously. The sliding ring 301 at the left end of the rotating ring 302 slides along the slide groove 103 of the support plate 102, and the support roller 104 at the right end of the support plate 102 fits against the outer wall of the rotating ring 302 to prevent swaying in the circumferential direction. The rotating ring 302 drives the metal brush 405 to rotate evenly around the cable through the fixing plate 305 to remove surface burrs through friction.

[0039] Protection and Dust Removal: In the protective assembly, the protective box 101 encloses the rotating component, and the protective cover 106 (fixed to the left end of the support plate 102) encloses the adjusting component and the metal brush 405, preventing burrs from splashing and impurities from entering; the dustproof plate 306 on the inner wall of the rotating ring 302 blocks dust, preventing it from affecting the sliding of the sliding ring 301 and the meshing of the gear 307 and the toothed ring 304. When the vacuum cleaner is turned on, the air vent 108 in the slot 107 at the lower end of the protective cover 106 is used to absorb burrs, preventing accumulation from affecting the polishing effect and keeping the surface clean.

[0040] Cable conveying: During the grinding process, the cable is smoothly conveyed along the axis under the guidance and support of the pulley 204. The metal brush 405 continuously rotates around the cable with the rotating ring 302, continuously and comprehensively grinding the cable in the conveying process, and finally completing the burr removal operation.

[0041] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
