Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, specifically a multi-dimensional adaptive automatic cable polishing device. Background Technology

[0002] As a core carrier in fields such as power transmission and communication, cables are widely used in various scenarios such as power systems, rail transit, petrochemicals, and underground utility tunnels. The surface quality of cables directly affects the installation of subsequent accessories, insulation performance, and long-term operational stability. Among these processes, the grinding of the insulation layer and metal sheath during the manufacturing of cable accessories is a key pretreatment step. Precise grinding is required to remove the surface oxide layer, burrs, impurities, and residual semi-conductive layer to ensure that the surface roughness and cylindricity of the cable meet the installation standards. This ensures a tight fit between the accessories and the cable, avoids safety hazards such as insulation breakdown and short circuits caused by localized electric field concentration, and ultimately extends the overall service life and operational reliability of the cable.

[0003] Existing cable polishing devices often require manual pressing of the cable to bring it into contact with the polishing belt when polishing the insulation layer. The disadvantages of such devices are that they are labor-intensive and have low safety. Existing polishing devices generally only have one polishing belt, and the cable needs to be rotated when the polishing direction needs to be changed, which reduces work efficiency. At the same time, existing polishing devices cannot adaptively adjust the polishing distance according to different cable diameters, which can easily cause uneven polishing thickness around the perimeter. Therefore, those skilled in the art provide a multi-dimensional adaptive automatic cable polishing device to solve the problems mentioned in the background art. Summary of the Invention

[0013] (III) Beneficial Effects This invention provides a multi-dimensional adaptive automatic cable polishing device. It has the following beneficial effects: In this invention, by setting up a conveying structure, the cable is placed between two clamping plates, and the motor is controlled to drive the bidirectional lead screw to rotate. The threaded connection between the bidirectional lead screw and the two first connecting sleeves drives the two clamping plates to clamp the side wall of the cable. Then, by controlling the third drive motor to drive the transmission lead screw to rotate, the cable clamped at the upper end is moved to the rear side under the threaded connection between the transmission lead screw and the second connecting sleeve. The whole process reduces manual feeding, achieving speed while ensuring safety during processing.

[0014] In this invention, by setting a positioning structure, during use, the cable is conveyed to the front by a conveying structure. When the sidewalls of multiple pressure plates contact the sidewall of the cable according to the cable diameter, they are pushed to the other side. During the pushing process, the connecting rod drives the movable plate to slide and connect inside the fourth slide groove. At the same time, the second spring is compressed. During the compression process, the top rod is pushed to one side and contacts the sidewall of the second pressure sensor. The second pressure sensor detects the pressure on the second spring to determine the diameter of the cable, which is convenient for adjustment during subsequent grinding. At the same time, during the conveying process, the sidewalls of multiple rollers roll on the sidewall of the cable respectively to facilitate the conveying.

[0015] In this invention, a grinding structure is provided. During use, the cable is conveyed to the inside of the connector through the positioning structure, and the other end of the cable is clamped by the rear clamping structure. Then, the diameter of the cable is detected by the positioning structure and fed back to the control panel. Subsequently, the sliding connecting plate is pushed to one side by rotating the adjusting bolt. During the pushing process, the connecting plate is slidably connected to the side walls of the two sliders. When the side wall of the grinding wheel contacts the side wall of the cable, the side wall of the sliding plate contacts the first pressure sensor. At the same time, the shape of the first spring changes. By adjusting the parameters of the first pressure sensor to be consistent with the parameters of the second pressure sensor, the position of the connecting plate is fixed by the fixing bolt after the adjustment is completed. The first drive motor drives the grinding wheel to rotate to achieve the grinding treatment of the side wall of the cable. The grinding wheel and the connector are detachably connected, which is convenient for replacement according to different processing and grinding requirements.

[0016] In this invention, by setting a grinding structure and making the connection between the connector and the fixing part a rotatable connection, the second drive motor drives the drive gear to rotate during the grinding process. The meshing transmission relationship between the drive gear and the driven gear drives the connector to rotate rapidly. During the rotation, the front and rear protective shells are also rotated, thereby realizing the circumferential grinding of the cable sidewall, improving the overall work efficiency and avoiding the need to adjust the position of the potential.

The cable is transmitted to the inside of the connector 208 through the positioning structure 6, and the other end of the cable is clamped by the rear clamping structure. Then, the diameter of the cable is detected by the positioning structure 6 and fed back to the control panel 4. Subsequently, the sliding connecting plate 221 is pushed to one side by rotating the adjusting bolt 222. During the pushing process, the connecting plate 221... Plate 216 is slidably connected to the sidewalls of the two sliders 224. When the sidewall of the grinding wheel 214 contacts the sidewall of the cable, the sidewall of the slide plate 218 contacts the first pressure sensor 220. At the same time, the shape of the first spring 217 changes. By adjusting the parameters of the first pressure sensor 220 to match the parameters of the second pressure sensor 611, the position of the connecting plate 216 is fixed by the fixing bolt 215 after adjustment. The first drive motor 207 drives the grinding wheel 214 to rotate to achieve grinding of the sidewall of the cable.

The cable is conveyed to the present location via the conveying structure 3. When the side walls of the pressure plates 604 contact the side walls of the cable according to the cable diameter, they are pushed to the other side.

First connecting sleeves 301 are symmetrically threaded onto the side wall of the bidirectional lead screw 302. The upper end of a connecting sleeve 301 is fixedly connected to the lower end face of two horizontal plates 304.

[0028] Working principle: This application is a multi-dimensional adaptive automatic cable polishing device. By placing the cable between two clamping plates 305, the control motor drives the bidirectional lead screw 302 to rotate. The threaded connection between the bidirectional lead screw 302 and the two first connecting sleeves 301 drives the two clamping plates 305 to clamp the side wall of the cable. Then, by controlling the third drive motor 306 to drive the transmission lead screw 311 to rotate, the transmission lead screw 311 and the second connecting sleeve 310 threaded connection drive the upper clamped cable to move backward. The whole process reduces manual feeding, achieving speed while ensuring safety during processing. The cable is conveyed to the front by the conveying structure 3. When the side walls of multiple pressure plates 604 come into contact with the side wall of the cable according to the diameter of the cable, they are pushed to the other side. During the pushing process, the connecting rod 607 drives the movable plate 608 to slide and connect inside the fourth slide groove 605. At the same time, the second spring 609 is compressed. During the compression process, the push rod 606 is pushed to one side and the side wall comes into contact with the side wall of the second pressure sensor 611. The second pressure sensor 611 detects the pressure on the second spring 609 to determine the diameter of the cable, which is convenient for adjustment during the subsequent grinding process. At the same time, during the conveying process, the side walls of multiple rollers 602 roll on the side wall of the cable respectively to facilitate the conveying. The cable is conveyed into the connector 208 through the positioning structure 6, and the other end of the cable is clamped by the clamping structure on the rear side. Then, the diameter of the cable is detected by the positioning structure 6 and fed back to the control panel 4. Then, the sliding connecting plate 221 is pushed to one side by rotating the adjusting bolt 222. During the pushing process, the connecting plate 216 is slidably connected to the side wall of the two sliders 224. When the side wall of the grinding wheel 214 contacts the side wall of the cable, the side wall of the slide plate 218 contacts the first pressure sensor 220. At the same time, the shape of the first spring 217 changes. By adjusting the parameters of the first pressure sensor 220 to be consistent with the parameters of the second pressure sensor 611, the position of the connecting plate 216 is fixed by the fixing bolt 215 after the adjustment is completed. The first drive motor 207 drives the grinding wheel 214 to rotate to achieve the grinding treatment of the side wall of the cable. The grinding wheel 214 and the connector 223 are detachably connected, which is convenient to replace them according to different processing and grinding requirements. By setting the connector 208 and the fixing member 209 as a rotatable connection, the second drive motor 210 drives the drive gear 211 to rotate during the grinding process. The meshing transmission relationship between the drive gear 211 and the driven gear 212 drives the connector 208 to rotate rapidly. During the rotation, the front protective shell 213 and the rear protective shell 203 are driven to rotate, thereby realizing the rotational grinding of the cable sidewall, improving the overall work efficiency, and avoiding the need to adjust the position of the potential.
