Description

Technical Field

[0001] The invention belongs to the technical field of grinding devices, and more specifically, particularly relates to a grinding device for cable insulation sleeves. Background Art

[0002] Cable insulation sleeve is a kind of sleeve material used to protect cables from environmental factors, physical damage, chemical corrosion, and ensure the stability of cable electrical performance. It plays an important role in many fields such as power transmission, communication systems, and building wiring. After the existing cable insulation sleeve is welded, in order to ensure the smoothness of the tube body, it is often necessary to use a separate grinding device to grind the weld of the cable insulation sleeve;

[0003] The existing grinding device for cable insulation sleeve still has the following shortcomings when used:

[0004] 1. Most existing grinding devices cannot grind the inner and outer wall welds of the casing at the same time.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the present invention, by providing the side rods, the first springs, the first threaded rings and the clamping strips, the two groups of first threaded rings will move toward the middle of the two side rods under the rotation, and the two groups of first threaded rings will drive the two groups of clamping strips to move toward the middle on the side rods.

At this time, the cable insulation sleeve can be effectively fixed by the two groups of clamping strips. By means of staggered fixing, the cable insulation sleeve is evenly stressed when fixed, thereby enhancing the stability of its placement and avoiding the sleeve from being stressed in one place. In this way, the risk of the sleeve being broken or falling off due to the concentrated stress can be reduced, and the stability and durability can be improved.

[0022] In the present invention, an adjusting rod, a third driving motor, a rotating shaft, a gear and a cleaning ring are provided.

At this time, the device can be controlled to move the inner and outer weld positions of the cable insulating sleeve to a state in contact with the two cleaning rings. At this time, the third driving motor can be started. Under the action of the third driving motor, the rotating shaft is driven to rotate accordingly. Under the rotation of the rotating shaft, the gear is driven to rotate accordingly. Since the two gears are meshed, the other rotating shaft will also rotate in the opposite direction. At this time, the two cleaning rings will clean the weld positions inside and outside the cable insulating sleeve, which can effectively remove oil, dust and other impurities, effectively avoid their influence on grinding, and help improve the reliability and insulation effect of the joint.

[0023] In the present invention, by providing a rotating shaft and a grinding bar, the weld position of the cable insulation sleeve can be moved to a position directly opposite to the two groups of grinding bars.

[0024] In the present invention, by providing a rotating shaft, an insert rod, a second threaded ring and a grinding strip, the second threaded ring is rotated again on the rotating shaft before grinding, and then the positions of the two insert rods are adjusted. At this time, the rebound distance of the two groups of grinding strips is limited under the adjustment of the two insert rods, so that the device also has the function of adjusting the grinding thickness of the cable insulation sleeve, so that the insulation sleeve can better adapt to cables of different diameters, ensure that the sleeve and the cable have a good fit, avoid gaps or excessive compression, thereby improving the sealing and insulation performance;

At this time, the two sets of connecting blocks 55 are driven to slide outward inside the two sets of slide grooves 51. Since the two sets of grinding strips 48 are respectively maintained on the same horizontal line with the two sets of grinding plates 54, the grinding area can be expanded by expanding the two sets of grinding plates 54 outward, thereby effectively improving the efficiency and quality of grinding and avoiding the problem of repeated processing.

[0041] Working principle:

[0042] In the first step, when using, the cable insulation sleeve can be placed between the two groups of clamping strips 27, and then the two groups of first threaded rings 26 can be rotated on the two first screw rods 23. Since the two groups are in a threaded connection, the two groups of first threaded rings 26 will move toward the middle of the two side rods 22 under the rotation of the two groups of first threaded rings 26, and the two groups of first threaded rings 26 will drive the two groups of clamping strips 27 to move toward the middle on the side rods 22. At this time, the two groups of clamping strips 27 will squeeze the two groups of first springs 25 to compress them. At this time, the cable insulation sleeve can be effectively fixed by the two groups of clamping strips 27. By means of staggered fixing, the cable insulation sleeve is evenly stressed when fixed, thereby enhancing the stability of its placement and avoiding the sleeve from being subjected to concentrated stress in one place. In this way, the risk of the sleeve being broken or falling off due to concentrated stress can be reduced, thereby improving stability and durability.

[0043] In the second step, after the cable insulating sleeve is fixed, the two second threaded rings 43 can be rotated on the two rotating shafts 36. The rotation of the two second threaded rings 43 will drive the two plug rods 41 to move outward inside the two strip grooves 38. At this time, the two plug rods 41 will slide into the two groups of wedge-shaped grooves 49, and then squeeze the two groups of grinding strips 48. At this time, the two groups of grinding strips 48 will drive the two groups of U-shaped frames 46 to slide inside the two inner plates 45. At this time, the two groups of U-shaped frames 46 will drive the two groups of second springs 47 to be compressed. At this time, a part of the two groups of grinding strips 48 will be retracted into the rotating shaft 36. At this time, the first drive motor 13 can be started. Under the action of the first drive motor 13, the electric telescopic rod 14 will be driven to extend and retract. At this time, the electric telescopic rod 14 will drive the adjusting rod 15 welded thereto to move inside the cross groove 12. At this time, when adjusting The movement of the rod 15 will drive the cable insulation sleeve to move accordingly. At this time, the rotating shaft 36 located at the rear will be inserted into the cable insulation sleeve, and the other rotating shaft 36 will be on the side wall of the cable insulation sleeve. At this time, the device can be controlled to move the inner and outer weld positions of the cable insulation sleeve to a state where they are in contact with the two cleaning rings 44. At this time, the third drive motor 35 can be started. Under the action of the third drive motor 35, the rotating shaft 36 will be driven to rotate accordingly, and the rotation of the rotating shaft 36 will drive the gear 37 to rotate accordingly. Since the two gears 37 are meshed, the other rotating shaft 36 will also rotate in the opposite direction. At this time, the two cleaning rings 44 will clean the weld positions inside and outside the cable insulation sleeve, which can effectively remove oil, dust and other impurities, effectively avoid their influence on grinding, and help improve the reliability and insulation effect of the joint.

[0044] The third step is that after the cleaning is completed, the second step can be repeated to move the weld position of the cable insulation sleeve to a position directly opposite to the two sets of grinding strips 48. At this time, the rotating shaft 36 is started to drive the two sets of grinding strips 48 to rotate, so that the device can grind the inner and outer walls of the cable insulation sleeve at the same time, ensuring the continuity and uniformity of the insulation layer, avoiding the electric field concentration caused by local unevenness, thereby improving the overall insulation level, and ensuring the accurate size of the sleeve, and ensuring the tightness and electrical performance after assembly;

[0045] The fourth step is to rotate the second threaded ring 43 on the rotating shaft 36 again before grinding, and then adjust the positions of the two plug rods 41. At this time, the rebound distance of the two groups of grinding strips 48 will be limited under the adjustment of the two plug rods 41, so that the device also has the function of adjusting the grinding thickness of the cable insulation sleeve, so that the insulation sleeve can better adapt to cables of different diameters, ensure good fit between the sleeve and the cable, avoid gaps or excessive compression, thereby improving the sealing and insulation performance;

[0046] The fifth step, when the weld is larger, the two sets of third threaded rings 53 can be rotated on the two sets of second screws 52. The rotation of the two sets of third threaded rings 53 will drive the two sets of connecting blocks 55 to move outward. At this time, the two sets of connecting blocks 55 will drive the two sets of grinding sheets 54 to slide outward inside the two sets of slide grooves 51. Since the two sets of grinding strips 48 are respectively maintained on the same horizontal line with the two sets of grinding sheets 54, the grinding area can be expanded by expanding the two sets of grinding sheets 54 outward, thereby effectively improving the efficiency and quality of grinding and avoiding the problem of repeated processing.
