[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a cable head processing device for a high-voltage cable, comprising a base 1, a fixed frame 3 is fixedly connected to the top of the base 1, a movable frame 4 is arranged inside the fixed frame 3, a servo motor 5 is fixedly connected to the front side of the movable frame 4, the output end of the servo motor 5 passes through the movable frame 4 and is fixedly connected to a worm 6, a hollow disc 7 is arranged at the top middle part of the base 1, the left and right sides of the inside of the hollow disc 7 are both rotatably connected to the first circular ring 8, the adjacent sides of the two first circular rings 8 are fixedly connected to the hollow worm gear 9, the hollow worm gear 9 is meshed with the worm 6, and a plurality of support rods 10 are fixedly connected to the inside of the hollow worm gear 9 at equal intervals. , one end of the plurality of support rods 10 is fixedly connected to the same second circular ring 11, a plurality of hollow columns 12 are equidistantly arranged around the outer side of the second circular ring 11, one end of the hollow column 12 passes through the second circular ring 11, a plurality of limiting holes 14 are equidistantly opened on one side of the hollow column 12, a bolt 15 is threadedly connected to one side of the hollow column 12, one end of the bolt 15 passes through the second circular ring 11 and the limiting hole 14 in sequence, a blade 13 is fixedly connected to one end of the hollow column 12, a clamping mechanism 2 is arranged on the left and right sides of the top of the base 1, the rear end of the worm 6 is rotatably connected to the inner rear side of the movable frame 4, and a plurality of bolts 15 are respectively threadedly connected to the corresponding inner sides of the limiting holes 14;

[0032] Specifically, the limit of the hollow column 12 can be released by first loosening the bolt 15, and then the blades 13 on all sides are moved toward the middle at the same time until they are in close contact with the outer skin of the cable. This design ensures that the blades 13 are in uniform contact with the outer skin of the cable. Once the blades 13 are in close contact with the outer skin of the cable, the operator tightens the bolts 15 to fix the hollow column 12 in an appropriate position. Subsequently, the worm 6 starts to rotate through the drive of the servo motor 5. Since the hollow worm gear 9 is engaged with the worm 6, it will also rotate with the rotation of the worm 6. In this process, the blade 13 will move with the rotation of the hollow worm gear 9, thereby cutting and stripping the cable all around. This design not only makes the cutting work more uniform, but also can adjust the cutting distance of the blade 13 according to cables of different diameters. The operator can accurately control the distance between the blade 13 and the outer skin of the cable to ensure that the cut outer skin of the cable is both neat and uniform, which can avoid the need for repeated cutting and greatly improve the efficiency of cable stripping.

[0033] Reference Figure 1 and Figure 4 The clamping mechanism 2 includes a support seat 201 and a connecting plate 208. The two support seats 201 are fixedly connected to the left and right sides of the top of the base 1 respectively. The top of the support seat 201 is fixedly connected with a hollow plate 202. The inner side of the hollow plate 202 is fixedly connected with a cylinder 203. The output end of the cylinder 203 is fixedly connected with a rack 204. The front and rear sides of the two hollow plates 202 are both provided with U-shaped plates 205. One end of the U-shaped plate 205 passes through the hollow plate 202. The bottom of the U-shaped plate 205 is rotatably connected with a first rotating shaft 206. The front and rear ends of the inner bottom of the two hollow plates 202 The first rotating shafts 206 are connected to the corresponding second rotating shafts 207 through connecting plates 208, and a special-shaped gear 209 is fixedly connected to one side of the connecting plate 208. The special-shaped gears 209 are meshed with the front and rear sides of the corresponding racks 204, and a clamping plate 210 is fixedly connected to one side of the U-shaped plate 205. A U-shaped frame 211 is fixedly connected to one side of the clamping plate 210. Multiple rollers 212 are equidistantly connected to the inside of the multiple clamping plates 210. The size of the hollow worm wheel 9 matches the internal size of the hollow disc 7.

[0034] Specifically, the rack 204 can be pushed to move to one side by the cylinder 203. In this process, due to the meshing relationship between the special-shaped gear 209 and the rack 204, the special-shaped gear 209 will rotate accordingly, and this rotational force will be transmitted to the second rotating shaft 207, thereby rotating it, and the first rotating shaft 206 is connected to the second rotating shaft 207 through the connecting plate 208, so when the second rotating shaft 207 rotates, the first rotating shaft 206 will also rotate accordingly, and the clever design of this rotation is that it can drive the U-shaped plates 205 on both sides to move toward the middle, and since the clamping plate 210 is connected to the U-shaped plate 205, the clamping plate 210 will also move toward the middle, and finally the U-shaped frame 211, driven by the clamping plate 210, will fit tightly on the cable, realizing the limited clamping of the cable. This clamping method is very stable and can effectively prevent the cable from shaking or deflecting during processing, thereby avoiding the risk of damage to the metal core inside the cable. The roller 212 can make the cable smoother during transportation, reduce friction, and thus reduce wear on the cable surface. This improvement not only improves the processing efficiency of the cable, but also extends the service life of the cable.

[0035] Reference Figure 1 A controller 17 is fixedly connected to the right side of the front end of the fixed frame 3. The controller 17 is electrically connected to the cylinder 203 and the servo motor 5 respectively. A protective cover 18 is arranged on the outside of the controller 17. One side of the protective cover 18 is rotatably connected to the front side of the fixed frame 3.

[0036] Specifically, the operation of the cylinder 203 and the servo motor 5 can be controlled by the controller 17, and the protective cover 18 can protect the controller 17 from being damaged by external factors.

[0037] Reference Figure 1 and Figure 2 , the adjacent sides of the fixed frame 3 and the base 1 are provided with a slide groove 16, the top of the movable frame 4 is slidably connected with the corresponding inner part of the slide groove 16, and the bottom of the hollow disc 7 is slidably connected with the corresponding inner part of the slide groove 16;

[0038] Specifically, the slide groove 16 can facilitate the movable frame 4 and the hollow disc 7 to move left and right at the same time, so that the cable can be stripped at different positions conveniently.

[0039] Working principle: When using the device, first pass the cable to be processed through the clamping mechanisms 2 on both sides in turn, first limit and clamp it through the clamping mechanisms 2, then observe the diameter of the cable to be processed, and then loosen the bolts 15 to release the limit on the hollow column 12. At this time, move the blades 13 on all sides to the middle at the same time until they touch the cable, and then tighten the bolts 15 again. At this time, the servo motor 5 can drive the worm 6 to rotate, and the hollow worm wheel 9 will also rotate due to the engagement with the worm 6. At this time, the blade 13 will rotate with it to cut and strip the cable around. The cutting distance of the blade 13 can be adjusted according to cables of different diameters. The cable sheath is cut more evenly, and repeated cutting is not required, thereby improving the cable stripping efficiency and meeting the requirements. The user's needs are met, and after one end of the cable to be processed passes through the clamping mechanisms 2 on both sides in turn, the cylinder 203 can drive the rack 204 to move to one side. At this time, the special-shaped gear 209 will rotate accordingly due to the engagement with the rack 204, thereby driving the second rotating shaft 207 to rotate, and the first rotating shaft 206 will also rotate through the connecting plate 208, thereby driving the U-shaped plates 205 on both sides to move toward the middle, and the clamping plate 210 will drive the U-shaped frame 211 to move toward the middle until it contacts the cable, so that the cable can be limitedly clamped, and the cable is not easy to shake or deviate during processing, thereby avoiding the damage of the metal core inside the cable, and the roller 212 provided can facilitate cable transportation, thereby improving the practicality of the device.
