Description

Technical Field

[0001] This utility model relates to the field of cable dismantling tools, specifically to a cable insulation cutting device. Background Technology

[0002] Cable laying is often required in power distribution engineering construction. During the cable laying process, construction workers often need to peel off and cut the insulation of the cable ends to facilitate the electrical connection between the cable and the equipment.

[0003] Existing cable insulation cutting tools can be found in patent application number CN201910037649.3. This tool uses stripping spikes to penetrate the outer layer of cable insulation. The operator then holds the handle and drags a rotating drum along the cable, using the two stripping spikes to cut open the outer insulation to a suitable position. The drum rotates around a bearing, causing the two stripping spikes to rotate and cut the stripped outer insulation. However, this cable insulation cutting tool can only cut the cable insulation circumferentially. For cables with thick insulation, even after only circumferential cutting, it is still difficult to peel off the insulation completely.

[0004] Therefore, how to reduce the difficulty of stripping cable insulation is an urgent technical problem to be solved. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] To address the technical problem of reducing the difficulty of stripping cable insulation, this invention provides a cable insulation cutting device. This device can perform circumferential and longitudinal cutting on the cable insulation, reducing the difficulty of subsequent cable stripping.

[0026] It should be noted that the cable insulation cutting device of this utility model is used for, but not limited to, cable stripping. For ease of explanation, this utility model only uses the application of the cable insulation cutting device to cable stripping as an example. The principle of the cable insulation cutting device in other types of equipment is essentially the same as that in cable stripping, and will not be described in detail here.

[0027] Please see Figure 1 , Figure 1 This is a schematic diagram of the cable insulation cutting device according to one embodiment of the present invention. The cable insulation cutting device includes a support assembly 100, a circumferential cutting assembly 200, and a longitudinal cutting assembly 300. The support assembly 100 includes a frame 110 and a clamping member 120. The clamping member 120 is mounted on the frame 110 and is used to clamp the cable. The longitudinal cutting assembly 300 is mounted on the frame 110 and has a first cutting end that moves along the cable axial direction. The first cutting end is used to cut the cable insulation along the axial direction. The circumferential cutting assembly 200 is mounted on the frame 110 and has a second cutting end that moves along a circumferential trajectory. The second cutting end is used to cut the cable insulation circumferentially.

[0028] In this embodiment, the cable is first clamped and fixed using the clamping member 120. Then, the second cutting end moves along a circumferential trajectory, allowing it to cut the cable insulation circumferentially, ultimately completing the circumferential cutting of the cable insulation. Next, the first cutting end moves along the cable axis, cutting the cable insulation again, finally completing the longitudinal cutting of the cable insulation. Using the above-described cable insulation cutting device, both circumferential and longitudinal cutting of the cable insulation can be performed, reducing the difficulty of subsequent cable stripping.

[0029] In some embodiments, the circumferential cutting assembly 200 includes a second slide 210, a second cutter head 220, and a second drive member 230. The second slide 210 is slidably disposed on the frame 110 along a circumferential trajectory. The second cutter head 220 is slidably disposed on the second slide 210 along the radial direction of the cable, and the second cutter head 220 has a second cutting end. The second drive member 230 is drively connected to the second cutter head 220 so that the second cutter head 220 can stop at any position on its sliding trajectory. When picking up or placing the cable on the clamp 120, the second drive member 230 can be used to drive the second cutter head 220 away from the cable to facilitate the cable picking and placing operation. When it is necessary to strip the cable insulation, the second drive member 230 can be used to drive the second cutter head 220 closer to the cable so that the second cutting end contacts and cuts the cable insulation.

[0030] Understandably, the second driving component 230 can adjust the relative position between the second cutting end and the cable, thereby adjusting the depth to which the second cutting end penetrates the insulation during the insulation cutting process. If the cable insulation is thick, the depth of the second cutting end embedded in the insulation can be increased. If the cable insulation is thin, the depth of the second cutting end embedded in the insulation can be decreased, thus allowing the circumferential cutting assembly 200 to adapt to cables of different specifications.

[0031] It should be noted that any implementation that allows adjustment of the relative position between the second cutter head 220 and the second slide block 210 is feasible. In some embodiments, the second slide block 210 has a second guide hole 211 and a second thread hole 212. The second cutter head 220 has a second guide rod that movably passes through the second guide hole 211. The second driving member 230 includes a second lead screw 231 that is screwed into the second thread hole 212, and one end of the second lead screw 231 is rotatably connected to the second slide block 210. Because the second guide rod movably passes through the second guide hole 211, the second cutter head 220 can slide relative to the second slide block 210. Since one end of the second lead screw 231 is rotatably connected to the second slide block 210 and screwed into the second thread hole 212, the second cutter head 220 can be pushed to slide relative to the second slide block 210 by rotating the second lead screw 231.

[0032] It is understood that, in order to facilitate the operator to rotate the second lead screw 231, in some embodiments, the end of the second lead screw 231 away from the second slide block 210 has a second knob 232, and the operator can rotate the second lead screw 231 by rotating the second knob 232.

[0033] Based on the above embodiments, in some embodiments, the frame 110 is provided with a second guide rail 111 in an annular shape, and the second slide 210 is slidably disposed on the second guide rail 111. By allowing the second slide 210 to slide along the second guide rail 111, the second cutter head 220 can be driven to move along a circumferential trajectory through the second slide 210.

[0034] In some embodiments, the second slide 210 has an outwardly extending second handle 213. An operator can grasp the second handle 213 and push it to move the second slide 210, thereby moving the second cutter head 220.

[0035] In some embodiments, the longitudinal cutting assembly 300 includes a first slide 310, a first cutter head 320, and a first drive member 330. The first slide 310 is slidably disposed on the frame 110 along a circumferential trajectory. The first cutter head 320 is slidably disposed on the first slide 310 along the radial direction of the cable, and the first cutter head 320 has a first cutting end. The first drive member 330 is drively connected to the first cutter head 320 so that the first cutter head 320 can stop at any position on its sliding trajectory. When picking up or placing the cable on the clamping member 120, the first drive member 330 can be used to drive the first cutter head 320 away from the cable to facilitate the picking and placing of the cable. When it is necessary to strip the cable insulation, the first drive member 330 can be used to drive the first cutter head 320 closer to the cable so that the first cutting end contacts and cuts the cable insulation.

[0036] Understandably, the first driving component 330 can adjust the relative position between the first cutting end and the cable, thereby adjusting the depth to which the first cutting end penetrates the insulation during the insulation cutting process. If the cable insulation is thick, the depth to which the first cutting end is embedded in the insulation can be increased. If the cable insulation is thin, the depth to which the first cutting end is embedded in the insulation can be decreased, thus allowing the slitting assembly 300 to adapt to cables of different specifications.

[0037] It should be noted that any implementation that allows adjustment of the relative position between the first cutter head 320 and the first slide block 310 is feasible. In some embodiments, the first slide block 310 has a first guide hole 311 and a first thread hole 312. The first cutter head 320 has a first guide rod 321, which is movably inserted through the first guide hole 311. The first driving member 330 includes a first lead screw 331, which is screwed into the first thread hole 312, and one end of the first lead screw 331 is rotatably connected to the first slide block 310. Because the first guide rod is movably inserted through the first guide hole 311, the first cutter head 320 can slide relative to the first slide block 310. Since one end of the first lead screw 331 is rotatably connected to the first slide block 310 and screwed into the first thread hole 312, the first cutter head 320 can be pushed to slide relative to the first slide block 310 by rotating the first lead screw 331.

[0038] It is understood that, in order to facilitate the operator to rotate the first lead screw 331, in some embodiments, the end of the first lead screw 331 away from the first slide block 310 has a first knob 332, and the operator can rotate the first lead screw 331 by rotating the first knob 332.

[0039] In some embodiments, the frame 110 has a first guide rail 112 laid along the cable axis, and a first slide block 310 is slidably disposed on the first guide rail 112. By allowing the first slide block 310 to slide along the first guide rail 112, the first cutter head 320 can be moved along the cable axis by the first slide block 310.

[0040] In some embodiments, the first slide 310 has an outwardly extending first handle 313. An operator can grasp the first handle 313 and push the first handle 313 to move the first slide 310, thereby moving the first cutter head 320.

[0041] In some embodiments, the frame 110 has a slot 113, and the clamping member 120 has a first state that prevents the cable from detaching from the slot 113, and a second state that allows the cable to enter and exit the slot 113. When it is necessary to pick up or put down the cable, the clamping member 120 can be adjusted to the second state, thereby allowing the cable to be placed into the slot 113 or removed from the slot 113. When it is necessary to fix the cable, the clamping member 120 can be adjusted to the first state, thereby allowing the clamping member 120 to clamp and fix the cable.

[0042] To better understand this utility model, the following is combined with... Figures 1 to 2 The technical solution of this utility model is described in detail below:

[0043] First, the cable is clamped and fixed using the clamping member 120, allowing the second driving member 230 to bring the second cutting head 220 closer to the cable, so that the second cutting end contacts and cuts the cable insulation. The operator can grasp the second handle 213 and push it to move the second slide 210, which in turn moves the second cutting head 220. This causes the second cutting end to move along a circumferential trajectory, thus cutting the cable insulation circumferentially and gradually completing the circumferential cutting of the cable insulation. Since the first guide rod is movably inserted through the first guide hole 311, the first cutting head 320 can slide relative to the first slide 310. Because one end of the first lead screw 331 is rotatably connected to the first slide 310 and screwed to the first threaded hole 312, rotating the first lead screw 331 can push the first cutting head 320 to slide relative to the first slide 310, thereby causing the first cutting end to move along the cable axis and cut the cable insulation again, finally completing the longitudinal cutting of the cable insulation. The cable insulation cutting device described above can be used to perform circumferential and longitudinal cuts on the cable insulation, reducing the difficulty of subsequent cable stripping.

[0044] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
