Description

Technical Field

[0001] The invention relates to a multifunctional cable stripping tool. Background Art

[0002] Generally, the cable structure is relatively complex, including multiple layers such as conductor, insulation layer, shielding layer, lead sheath, sheath layer, filling layer, and armor layer. When performing cable maintenance operations, operators need to carry corresponding tools according to different cables to strip the cable structure.

[0003] A careful analysis of existing tools for stripping cables reveals the following problems:

[0004] First, many existing wire stripping tools are only suitable for cables of specific types and specifications, and their functions are relatively simple, which limits their application scope and practicality.

[0005] Second, the wire stripping knife is prone to wear after frequent use, and the existing wire stripping tools are inconvenient to disassemble and assemble, making them difficult to replace.

[0006] 3. During manual operation, especially when it is necessary to strip multiple cable structures such as lead sheaths and sheaths, it is necessary to carry multiple sets of cutting tools to strip the corresponding structures. The portability is low and the operation steps are cumbersome, which makes it difficult to meet the needs of fast operation.

[0007] Fourth, the existing cable stripping tools are very laborious to use when encountering resistance during the process of stripping the cable, and the effect is not ideal.

[0008] 5. Existing wire stripping tools may have unstable precision during the wire stripping process, resulting in incomplete wire stripping or damage to the underlying cable, affecting the subsequent use effect and safety of the cable.

[0009] In view of this, the inventor has specially developed a multifunctional cable stripping tool based on his professional technical level in long-term research, design and manufacturing of cables, accumulated rich experience and familiarity with cable products, and this case is thus generated.

[0046] like Figures 1 to 9 As shown, a multifunctional cable stripping tool disclosed by the present invention, the main frame 10 includes a first fixed end block 11, a second fixed end block 12, a movable end block 13 and a bracket guide rod 14.

[0047] The first fixed end block 11 and the second fixed end block 12 are respectively fixed to the two ends of the support guide rod 14, and the movable end block 13 is assembled on the support guide rod 14 in a manner that it can slide up and down. Specifically, a guide hole 132 can be opened on the movable end block 13, and the support guide rod 14 is inserted into the guide hole 132. A bearing can be installed in the guide hole 132 to make the operation smoother. The movable end block 13 can slide up and down by the support guide rod 14 under the action of external force.

[0048] A movable handle 20 is provided on the outer side of the first fixed end block 11, and a first screw 21 extends through the center of the movable handle 20. The middle section of the first screw 21 is installed on the first fixed end block 11 through a first stepped sleeve 22 to limit the axial displacement, so that the first screw 21 can rotate on the first fixed end block 11 but will not move axially relative to the first fixed end block 11. Specifically, the first stepped sleeve 22 is fixed to the middle section of the first screw 21, and the stepped groove of the first stepped sleeve 22 cooperates with the hole edge of the first fixed end block 11, so that the axial displacement between the first screw 21 and the first fixed end block 11 is limited. The inner end of the first screw 21 is fixed to the movable end block 13 by threaded cooperation with the screw fixing seat 23. When the movable handle 20 is rotated, the first screw 21 rotates accordingly, which can drive the movable end block 13 to move up and down along the bracket guide rod 14 to meet the needs of stripping cables of different sizes. In order to fix the movable handle 20 and the first screw rod 21 relative to the first fixed end block 11 after adjustment, an anti-rotation positioning member 24 for positioning the first screw rod 21 is further provided between the first fixed end block 11 and the movable end block 13, and the anti-rotation positioning member 24 is fixed to the inner side of the first fixed end block 11. The anti-rotation positioning member 24 is specifically composed of a pipe clamp 241 and a bolt 242. The base of the pipe clamp 241 is fixed to the inner side of the first fixed end block 11, and the pipe clamp 241 is sleeved on the first screw rod 21. After the movable handle 20 is rotated to adjust the first roller 33 and the second roller 63 to clamp the cable, the pipe clamp 241 is tightly held (fastened together) by rotating the bolt 242, so as to achieve the effect of fixing the first screw rod 21.

[0049] A rotatable double wheel frame 30 is arranged inside the movable end block 13, and a first positioning member 31 for positioning the double wheel frame 30 is arranged between the double wheel frame 30 and the movable end block 12. The first positioning member 31 can be a screw, and the double wheel frame 30 is positioned on the movable end block 12 by screwing the screw. As shown in the drawings, the screw fixing seat 23 is mounted on the double wheel frame 30, and the screw fixing seat 23 is assembled on the movable end block 13 with the help of the double wheel frame 30. The inner end of the first screw 21 passes through the first through hole 131 of the movable end block 13 and cooperates with the thread of the screw fixing seat 23. In this way, when the first screw 21 is rotated, the movable end block 13 is driven to move up and down along the bracket guide rod 14 through the screw fixing seat 23 and the double wheel frame 30. In the figure, the first positioning member 31 can position the screw fixing seat 23 and the double wheel frame 30 together on the movable end block 12. Two groups of slide grooves 34 are also formed on the double-wheel frame 30, and the two first rollers 32 are respectively mounted on the corresponding group of slide grooves 34 in an adjustable positioning manner through their own first roller shafts 33. Specifically, the slide groove 34 is designed in an eight-shaped shape, and the first roller shaft 33 adopts a screw and nut combination. The first roller shaft 33 moves in the slide groove 34 to change the position of the first roller shaft 33 on the slide groove 34 of the double-wheel frame 30, so that the position and spacing of the two first rollers 32 are changed, so that the triangular fulcrum formed between the first roller 32 and the second roller 63 described later can be adjusted to better adapt to cables with different specifications and outer diameters.

[0050] A fixed handle 40 is provided on the outer side of the second fixed end block 12, and a cutter wheel seat 50 is installed on the inner side of the second fixed end block 12. A single wheel frame 60 is installed on the cutter wheel seat 50 in an adjustable lifting manner, and a second positioning member 61 for fixing the single wheel frame 60 is provided between the single wheel frame 60 and the cutter wheel seat 50. A second roller 63 is installed on the single wheel frame 60 through a second roller shaft 62, and the second roller 63 and the two first rollers 33 form a triangular fulcrum for guiding the cable. In order to better guide the cable, the first roller 33 adopts a V-shaped roller, and the second roller 63 adopts a PU bearing roller. The cutter wheel seat 50 is also provided with a tool holder 70 in an adjustable lifting manner, a cutter head 71 is installed on the tool holder 70, and a second screw rod 72 is also provided on the tool holder 70. The outer end of the second screw rod 72 extends to the outer side of the second fixed end block 12 and is connected to the adjusting nut 73. The adjusting nut 73 drives the second screw rod 72 and the tool holder 70 to move up and down to adjust the cutting depth of the cutter. A third positioning member 74 is provided between the tool holder 70 and the cutter wheel seat 50. The side of the tool holder 70 may be engraved with a scale mark 75 showing the lifting height. The scale on the tool holder 70 can more accurately control the cutting depth. The third positioning member 74 (knurled high head screw) on the side of the cutter wheel seat 50 can fix the tool holder 70 after the adjustment is completed to prevent the tool from shaking during cutting and causing uneven cutting.

[0051] Specifically, a first positioning groove 51 and a second positioning groove 52 are formed on the cutter wheel seat 50. A screw hole communicating with the first positioning groove 51 or the second positioning groove 52 is provided on the side wall of the cutter wheel seat 50. The single wheel holder 60 is adjustably inserted into the first positioning groove 51, and the cutter holder 70 is adjustably inserted into the second positioning groove 52. The second positioning member 61 and the third positioning member 74 are screws, and the screws are assembled in the screw holes. The inner ends of the screws extend into the first positioning groove 51 or the second positioning groove 52. When the single wheel holder 60 and the cutter holder 70 are adjusted in place, the single wheel holder 60 and the cutter holder 70 are fixed on the cutter wheel seat 50 by means of the second positioning member 61 and the third positioning member 74 respectively. There are at least two types of cutter holders 70, and the cutter head 71 on the cutter holder 70 is a single hob ( Figure 2 ), double hob ( Figure 8 ) or sheath cutter ( Fig. 9 ). Among them, the single hob is mainly used for cutting the lead sheath layer with higher hardness. The sheath cutter can spiral-cut the cable insulation layer and sheath layer. The double hob (double-edged) can be used for rolling the lead sheath, and two axial cuts are formed on the surface after rolling. The lead sheath is peeled off along the axial cuts with a pair of pliers or other tools.

[0052] When the present invention is actually used, the cable is placed between the first roller 33 and the second roller 63, and is guided by the first roller 33 and the second roller 63 when the cable is pulled. The cable is cut by the cutter head 71 on the cutter holder 70 during the pulling process to achieve peeling. The present invention rotates the double wheel holder 30, the cutter holder 70, and the single wheel holder 60 by 90° respectively, and can also realize the transformation from longitudinal cutting of the tool to circular cutting.

[0053] The present invention is configured with multiple cutter holders 70 having different cutter heads 71, integrating various wire stripping and cutting functions, and can significantly improve the efficiency and quality of cable production. The tool of the present invention is reasonably designed, can adapt to cables with different diameters and materials, reduces the number of tools required to be carried, and improves portability. At the same time, the present invention also pays attention to the safety and convenience of operation. By optimizing the tool structure and operation method, the operation difficulty is reduced and the operation safety is ensured. The present invention designs a multifunctional wire stripping tool that can adapt to different cable diameters (45 mm - 150 mm) and materials (plastic, lead) to improve the wire stripping speed and quality. The cutting knife of the tool of the present invention is convenient to disassemble and replace. The tool of the present invention can be equipped with multiple sets of cutter heads 71 such as lead stripping hobs and sheath cutters, and the lead sheath layer, sheath layer and other multi-layer cable structures can be simultaneously stripped by replacing the cutter head 71. The tool design of the present invention takes into account the characteristics of human body force application, uses both hands to apply force for cutting simultaneously, avoids uneven force and excessive resistance during cutting, and improves the cutting effect. The side of the cutter holder 70 of the present invention is engraved with scales, which can accurately control the cutting depth and improve the accuracy.

[0054] The embodiments described above are only for illustrating the technical ideas and features of the present invention, and their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly, but they do not limit the patent scope of the present invention.
