Description

Technical Field

[0001] This invention relates to the field of cable grinding and processing equipment, specifically a cable insulation layer grinding device. Background Technology

[0002] Cables are wire products used to transmit electrical energy or signals. They are usually made up of several or several groups of conductors twisted together like a rope. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer, and has the characteristics of being internally energized and externally insulated.

[0003] Grinding is a crucial step in cable manufacturing, eliminating surface contamination and defects and enhancing the adhesion of protective coatings. It typically involves sandblasting or mechanical polishing. Existing grinding equipment first clamps and positions the cable's outer side using two jigs. A rotating disc drives a grinding wheel in a circular motion, allowing the wheel to thoroughly grind the cable's insulation layer. To ensure smooth grinding, a support plate is placed on the opposite side of the grinding wheel to support the cable's outer side and prevent tilting during grinding. However, when the support plate contacts the grinding area, the height of the grinding area is often insufficient to align with the grinding area of ​​the insulation layer, resulting in a suspended state. This makes it difficult to provide adequate support for the cable's outer side, compromising the accuracy of the grinding of the cable insulation layer. Summary of the Invention

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1-8 The cable insulation grinding device shown in the figure includes an electric slide table 1 and two clamping members 2 symmetrically fixedly installed on the top of the electric slide table 1. The two clamping members 2 clamp and position the outer side of the cable. A movable seat 3 is slidably installed on the inner side of the electric slide table 1. An annular shell 4 is fixedly installed on the top of the movable seat 3. An installation ring 5 is rotatably installed on the inner side of the annular shell 4. Two symmetrically distributed electric grinding wheels 6 are arranged on the inner ring of the installation ring 5. The two electric grinding wheels 6 grind the insulation layer of the cable and provide support for the cable. The device also includes a side pressure mechanism to enable the two electric grinding wheels 6 to grind the insulation layer smoothly. The side pressure mechanism is installed on the inner ring of the installation ring 5.

[0036] The side-pressing mechanism includes two pressure rollers 7 symmetrically arranged within the inner ring of the mounting ring 5. The pressure rollers 7 provide support for the contact between the electric grinding wheel 6 and the insulating layer. The side-pressing mechanism also includes two fixing plates 10 symmetrically arranged within the inner ring of the mounting ring 5. Two symmetrically distributed slide cylinders 11 are fixedly mounted on the side of the fixing plates 10 away from the mounting ring 5. A slider 12 is slidably mounted on the inner side of each slide cylinder 11. A support rod 13 is fixedly mounted on the side of the slider 12 away from the fixing plate 10. The support rod 13 slides through the end of the slide cylinder 11 away from the fixing plate 10. The support rod 13 is located away from the slider 12. A sleeve 14 is fixedly installed at one end. Two pressure rollers 7 are located on the outer sides of two fixed plates 10, and the pressure rollers 7 are rotatably installed between two adjacent sleeves 14. This allows the outer side of the cable to contact the two pressure rollers 7 when the cable is inserted between the two clamping members 2. The reaction force of the pressure rollers 7 on the cable causes the pressure rollers 7 to drive the two sleeves 14 to move. The sleeves 14 push the slider 12 at the end of the support rod 13 to move along the inner side of the slide cylinder 11. A tension spring 15 is sleeved on the outside of the support rod 13, and the two ends of the tension spring 15 are fixedly assembled with the slider 12 and the slide cylinder 11, respectively. When the slider 12 moves, it can stretch the tension spring 15. The elastic tension of the tension spring 15 allows the pressure roller 7 to elastically clamp the outer side of the cable positioning. A toothed ring 16 is fixedly installed on the outer side of the mounting ring 5. A first motor 17 located below the mounting ring 5 is fixedly installed on the inner side of the annular shell 4. A first gear 18 is fixedly installed at the output end of the first motor 17, and the first gear 18 meshes with the toothed ring 16. Two electric grinding wheels 6 and two pressure rollers 7 are distributed in a crisscross pattern, so that when the first motor 17 starts, it can drive the mounting ring 5 along the [path / direction] via the first gear 18 and the toothed ring 16. The inner side of the annular shell 4 rotates, causing the mounting ring 5 to drive the electric grinding wheel 6 and the pressure roller 7 to make a circular motion along the outer side of the insulation layer. When the pressure roller 7 comes into contact with the grinding area of ​​the insulation layer, the rebound force of the tension spring 15 makes the pressure roller 7 press against the grinding area, so that the two pressure rollers 7 and the two electric grinding wheels 6 maintain support for the cable and achieve stable grinding of the cable. Both ends of the pressure roller 7 are frustum structures, and the length of the pressure roller 7 is less than the length of the electric grinding wheel 6, so that when the pressure roller 7 moves horizontally, it can move from the grinding area of ​​the insulation layer to the ungrinded position of the insulation layer through the inclined surfaces at both ends of the pressure roller 7.

[0037] Example 2: Please refer to Figures 2-6This embodiment further illustrates Example 1. The pressure-regulating mechanism shown in the figure includes two symmetrically fixed positioning blocks 8 fixedly installed inside the mounting ring 5. The positioning blocks 8 can provide positioning for the movement of the pressure roller 7. The pressure-regulating mechanism also includes a slide rod 19 fixedly installed between the two sliders 12. A groove is provided on the outer side of the slide cylinder 11 for the slide rod 19 to slide in a limited position, so that when the slider 12 moves, it can drive the slide rod 19 to move along the groove in the slide cylinder 11. Two fixing plates 10 are respectively fixedly installed on the outer side of the two positioning blocks 8. A slide plate 20 is fixedly installed on the outer side of the slide rod 19. A cavity is provided on the outer side of the positioning blocks 8 and the fixing plates 10 for the slide plate 20 to slide in a limited position. Two symmetrically distributed slide bars 21 are slidably installed on the inner side of the positioning blocks 8. A triangular tooth 22 is fixedly installed near one end of the slide plate 20. Both sides of the slide plate 20 have ratchet grooves that mate with the triangular tooth 22, and the inclined surface of the triangular tooth 22 faces the fixed plate 10. A first spring 23 is fixedly installed between the slide bar 21 and the inner side of the positioning block 8. When the cable is inserted between the two clamping members 2, the cable can push the pressure roller 7 to move, causing the two sliders 12 to push the slide plate 20 along the cavity of the positioning block 8 via the slide rod 19. This causes the ratchet groove on the slide plate 20 to move along the inclined surface of the triangular tooth 22, and the triangular tooth 22 pushes the slide bar 21 to compress the first spring 23. When the pressure roller 7 stops moving, the rebound force of the first spring 23 causes the slide bar 21 to push the triangular tooth 22 into the ratchet groove. Within the toothed groove, the slide plate 20 is limited to prevent the pressure roller 7 from causing cable extrusion before the electric grinding wheel 6 contacts the cable insulation layer. A sliding hole is provided on the inner side of the slide bar 21, and a push block 24 is fixedly installed inside the sliding hole. A push rod 25 is slidably installed inside the sliding hole. The side of the push block 24 away from the fixed plate 10 has an inclined structure. The width of the push rod 25 is smaller than the width of the sliding hole, and a push groove corresponding to the push block 24 is provided on the outer side of the push rod 25. When the push rod 25 moves, it can push the push block 24 through the inclined surface of the push rod 25. The push block 24 drives the slide bar 21 to move, causing the triangular locking teeth 22 at the end of the slide bar 21 to move away from the slide plate 20, thus unlocking the slide plate 20. The pressure roller 7 can then press against the outer side of the cable to achieve cable positioning. One end of the push rod 25 slides through the positioning block 8 and the mounting ring 5 and is fixedly mounted with a first arc-shaped block 26. Two symmetrically distributed fixing rings 27 are fixedly mounted on the inner side of the annular shell 4. Two second arc-shaped blocks 28, respectively in contact with the two first arc-shaped blocks 26, are fixedly mounted on the outer side of the fixing rings 27. When the mounting ring 5 rotates, it can drive the first arc-shaped blocks 26 on the push rod 25 to move along the outer side of the fixing rings 27, causing the first arc-shaped blocks 26 to contact the second arc-shaped blocks 28, thus moving the push rod 25 and unlocking the pressure roller 7, facilitating the positioning of the cable by the pressure roller 7. A second spring 29 is fixedly mounted between the outer side of the push rod 25 and the inner side of the positioning block 8, allowing the push rod 25 to compress the second spring 29 when it moves.When the first arc-shaped block 26 is moved away from the second arc-shaped block 28, the return force of the second spring 29 resets the push rod 25. Guide grooves for the triangular locking teeth 22 to slide and limit their movement are provided on both sides of the slide plate 20, with the ratchet groove located inside the guide groove, allowing the triangular locking teeth 22 to move along the inside of the guide groove and easily insert into it. Two symmetrically distributed positioning grooves are provided on the outer side of the push rod 25, and a protrusion for the positioning grooves to slide and limit their movement is provided in the sliding hole of the slide bar 21, providing support for the movement of the push rod 25 and facilitating the smooth movement of the push block 24 through the push groove. Two symmetrically distributed guide rings 39 are fixedly installed on the inner ring of the fixing ring 27, with the outer side of the guide rings 39 contacting the outer side of the first arc-shaped block 26, allowing the first arc-shaped block 26 to move between the two guide rings 39, improving the smoothness of its movement.

[0038] Example 3: Please refer to Figures 2-8This embodiment further illustrates other embodiments. The distance adjustment mechanism shown in the figure includes two annular disks 9 respectively fixedly installed on both sides of the mounting ring 5. The annular disks 9 can synchronously adjust the distance between the two electric grinding wheels 6. The distance adjustment mechanism also includes a turntable 30 rotatably installed inside the annular disk 9. A spiral bar 31 is fixedly installed on the outer side of the turntable 30. Two symmetrically distributed mounting grooves are opened on the outer side of the annular disk 9, and mounting blocks 32 are slidably installed on the inner side of each of the two mounting grooves. Mounting plates are opened at both ends of the electric grinding wheel 6. The electric grinding wheel 6 is composed of two mounting plates. The device consists of a plate, a grinding wheel body, and a motor. Two mounting plates are fixedly installed on the outer sides of two adjacent mounting blocks 32, providing support for the electric grinding wheel 6. Multiple arc-shaped grooves that mate with the spiral bars 31 are provided on the outer sides of the mounting blocks 32. When the turntable 30 rotates, the spiral bars 31 drive the two mounting blocks 32 to move closer together or further apart along the mounting grooves on the annular disc 9, thus enabling the two electric grinding wheels 6 to synchronously contact the outer side of the cable. This facilitates grinding cables of various sizes. An arc-shaped groove is fixedly installed on the inner ring of the turntable 30. A rack 33 is fixedly mounted between two annular discs 9. A transmission rod 41 is rotatably mounted on the inner side of the rack 34. A second motor 35 is fixedly mounted on the inner side of the mounting ring 5. A matching conical wheel 36 is fixedly mounted at the output end of the second motor 35 and on the outer side of the transmission rod 41. Second gears 37 that mesh with the two arc-shaped racks 33 are fixedly mounted at both ends of the transmission rod 41, enabling the second motor 35 to drive the transmission rod 41 to rotate via the two conical wheels 36. The transmission rod 41 then interacts with the corresponding arc-shaped racks 33 via the two second gears 37. The two turntables 30 rotate synchronously, which can adjust the two electric grinding wheels 6. Limiting strips 40 are fixedly installed on both sides of the mounting block 32. The inner side of the annular disk 9 is provided with a limiting groove for the limiting strips 40 to slide, which improves the stability of the movement of the mounting block 32. Two symmetrically distributed annular ribs 38 are fixedly installed on the outer ring of the annular disk 9. The inner side of the annular shell 4 is provided with annular grooves corresponding to the annular ribs 38. The mounting ring 5 can drive the annular ribs 38 to rotate along the inner side of the annular shell 4 through the annular disk 9, which improves the stability of the rotation of the mounting ring 5.

[0039] Working principle: First, the operator passes the cable through the two clamping parts 2 and the annular shell 4. The outer side of the cable contacts the outer side of the pressure roller 7. Utilizing the reaction force of the cable on the pressure roller 7, the cable pushes the pressure roller 7 to move. The pressure roller 7 pushes the two sleeves 14 to move, and the sleeves 14 push the support rod 13 to move. The support rod 13 pushes the slider 12 to move along the inner side of the slide cylinder 11. The slider 12 stretches the tension spring 15. At the same time, the two sliders 12 drive the slide rod 19 to move, causing the slide rod 19 to drive the slide plate 20 to move along the inner side of the positioning block 8. The ratchet grooves on both sides of the slide plate 20 push the corresponding triangular teeth 22 to move. The triangular teeth 22 push the slide bar 21 to move along the inner side of the positioning block 8, causing the slide bar 21 to compress the first spring 23. When the pressure roller 7 stops... When the movement stops, the rebound force of the first spring 23 pushes the slide bar 21 to reset, so that the triangular teeth 22 on the slide bar 21 insert into the current ratchet groove of the slide plate 20, thereby limiting the slide plate 20. The tension spring 15 cannot stretch the slider 12 to reset, maintaining the current position of the pressure roller 7, which makes it easy for the operator to install the cable into the inner side of the annular shell 4, so that the cable is between the two electric grinding wheels 6 and the two pressure rollers 7. Then, the operator adjusts the two clamping parts 2 to clamp and position the outside of the cable, and starts the second motor 35. The second motor 35 drives the transmission rod 41 to rotate, so that the second gears 37 at both ends of the transmission rod 41 drive the two turntables 30 to rotate along the inner side of the annular disk 9 through the two arc-shaped racks 33 respectively. The vortex on the outer side of the turntable 30 The arc-shaped groove on the mounting block 32, along with the mounting groove on the annular disc 9, causes the two mounting blocks 32 to move closer together, bringing the electric grinding wheel 6 close to the outside of the cable. At this time, the first motor 17 drives the first gear 18 to rotate, which in turn drives the mounting ring 5 to rotate via the gear ring 16. This causes the mounting ring 5 to move via the positioning block 8, which in turn drives the fixing plate 10 to move. The fixing plate 10, through the support rod 13 and the sleeve 14, drives the pressure roller 7 to rotate. The mounting block 32 drives the electric grinding wheel 6 to rotate, and the positioning block 8 drives the push rod 25 to move. The first arc-shaped block 26 on the push rod 25 contacts the second arc-shaped block 28 on the fixing ring 27, bringing the first arc-shaped block 26 into contact with the second arc-shaped block 28. The reaction force of block 28 on the first arc-shaped block 26 causes the first arc-shaped block 26 to push the push rod 25 to move. The push rod 25 compresses the second spring 29 and moves along the sliding hole of the slide bar 21. The push groove on the push rod 25 moves along the inclined surface of the push block 24, causing the push rod 25 to push the slide bar 21 to move through the push block 24. This causes the triangular locking teeth 22 on the slide bar 21 to move away from the ratchet groove of the slide plate 20, thereby unlocking the slide plate 20. Then, the rebound force of the tension spring 15 can be used to push the slider 12 to move the support rod 13. The support rod 13 drives the pressure roller 7 to contact the outside of the cable through the sleeve 14. At the same time, the electric grinding wheel 6 contacts the outside of the cable, achieving four-point positioning of the outside of the cable. As the mounting ring 5 rotates, the two electric grinding wheels 6 grind the cable insulation layer.After the pressure roller 7 moves half a circle, the first arc-shaped block 26 can contact the next second arc-shaped block 28, thus unlocking the pressure roller 7 again. Utilizing the elastic tension of the tension spring 15, the pressure roller 7 is pressed against the outer side of the insulation layer being ground, improving the stability of the electric grinding wheel 6's grinding of the insulation layer and enabling timely adjustment of the pressure roller 7's position. Finally, the operator starts the electric slide table 1, which moves the annular shell 4 via the moving seat 3, moving the electric grinding wheel 6 to another unground area of ​​the insulation layer, allowing for continued grinding. This achieves a stable grinding effect and ensures the grinding quality of the cable insulation layer.
