During the actual installation process, it is often necessary to peel off a few centimeters of the cable head to expose the metal core of the cable head, which is convenient for connecting the metal core to electrical equipment.

[0003] For large-diameter cables such as high-voltage cables, tools are usually used to circumcise the cable sheath, and then the sheath after circumcision is removed from the cable end.

[0024] As a further implementation scheme of the above invention: the front positioning disk 61 and the rear positioning disk 62 are both provided with mounting holes that cooperate with the guide rod 3. The front positioning disk 61 and the rear positioning disk 62 are mounted on the outside of the guide rod 3 through the mounting holes, ensuring that the rotating gear disk 2 and the guide rod 3 can drive a number of rotary cutting mechanisms 6 to rotate around the cable for circular cutting when rotating.

When the servo motor 8 drives a group of rotary cutters 63 to rotate, the transmission is transmitted through the transmission teeth 65 and the driven teeth 66, so that all the rotary cutters 63 in the rotary cutting mechanism 6 can be synchronously driven to deflect, thereby realizing circular cutting of cables with different diameters.

[0026] As a further implementation scheme of the above invention: both ends of the peeling knives 63 at the same position of several peeling mechanisms 6 are fixedly connected with a flexible shaft plug connector 67, the servo motor 8 is located on the side of the rotating gear disk 2 away from the peeling mechanism 6, the output shaft of the servo motor 8 passes through the side of the rotating gear disk 2 close to the peeling mechanism 6, and the output shaft of the servo motor 8 is fixedly connected with a flexible shaft plug connector 67.

The peeling knives 63 in adjacent peeling mechanisms 6 are transmitted through the transmission flexible shaft 7, ensuring that multiple peeling mechanisms 6 can realize transmission control, reducing the difficulty of adjusting the peeling knives 63 in the peeling mechanism 6, and at the same time ensuring that stable power transmission can still be carried out when the distance between adjacent peeling mechanisms 6 increases.

[0027] As a further implementation scheme of the above invention: the stepped telescopic mechanism 10 includes a plurality of movable telescopic sleeves 101, the number of the telescopic sleeves 101 is the same as the number of the peeling mechanisms 6, and the positions of the plurality of telescopic sleeves 101 and the plurality of peeling mechanisms 6 correspond one to one, and a plurality of movable telescopic sleeves 101 are arranged in the stepped telescopic mechanism 10.

The top of the clamping bracket 104 is in an open state and will not interfere with the rotation of the rotary cutting mechanism 6.

[0029] As a further implementation scheme of the above invention: the end of the output shaft of the multi-stage electric telescopic rod 11 is fixedly connected to a transmission arm 12, and a connecting rod is rotatably connected to the transmission arm 12, and the connecting rod is threadedly connected to the stepped telescopic mechanism 10, so as to ensure that the multi-stage electric telescopic rod 11 can drive the stepped telescopic mechanism 10 to extend. At the same time, the transmission arm 12 and the connecting rod are provided to facilitate the connection between the multi-stage electric telescopic rod 11 and the stepped telescopic mechanism 10.

[0030] As a further implementation scheme of the above invention: the locking mechanism 13 includes a mounting bracket 131 fixedly connected to the mounting disk 1 and a locking electric telescopic rod 132 fixedly mounted on the mounting bracket 131. Several locking mechanisms 13 cooperate with each other to fix the device to the outside of the cable, and at the same time make the cable located in the middle position of the device to ensure the accuracy of cable sheath circumcision. The output shaft of the locking electric telescopic rod 132 is toward the center position of the mounting disk 1, and a locking clamp 133 is fixedly connected to the output shaft of the locking electric telescopic rod 132. The locking clamp 133 is driven by the locking electric telescopic rod 132 in multiple groups of locking mechanisms 13 to move and tighten the cable, so that the device can be fixed to the outside of the cable to ensure stability when the cable end is stripped.

[0031] During specific implementation: the device is mounted on one end of the cable that needs to be stripped, and the position of the device at the end of the cable is adjusted so that the distance between the rotary cutting mechanism 6 on the side closest to the mounting plate 1 and the end of the cable is the length of the outer skin that needs to be stripped, and the positions of the multiple rotary cutting mechanisms 6 are initially adjusted according to the length of the cable stripping, so that the multiple rotary cutting mechanisms 6 are relatively evenly distributed at the positions of the cable end that need to be stripped; the locking electric telescopic rods 132 in the multiple locking mechanisms 13 are started, and the multiple locking electric telescopic rods 132 drive the locking clamping plates 133 to move toward the side close to the cable to clamp the cable, and the device is fixedly installed on the outside of the cable; the adjacent rotary cutting mechanisms 13 are adjusted to the same length as the cable stripping mechanism 6. The rotary cutter 63 in the cutting mechanism 6 transmits power through the transmission flexible shaft 7, the servo motor 8 starts to provide power, and is transmitted through the transmission flexible shaft 7, driving the rotary cutters 63 connected to the transmission flexible shaft 7 in the rotary cutter mechanism 6 to rotate, and is transmitted through the transmission ring 64 and the transmission tooth 65, driving the multiple rotary cutters 63 in the rotary cutter mechanism 6 to deflect to the side close to the cable; there are two ways for the rotary cutter 63 to cut the cable sheath into place, one is that before the rotary cutter mechanism 6 ring cuts the cable, the servo motor 8 drives the rotary cutter 63 to deflect directly to the ring cutting depth, and the other is that while the rotary cutter mechanism 6 ring cuts the cable, the servo motor 8 drives the rotary cutter 63 to gradually deflect to The cutting depth is determined by the starting of the driving motor 4, which drives the driving gear 5 and the rotating toothed disc 2 to rotate, and drives the plurality of peeling mechanisms 6 to rotate around the outer skin of the cable end through the transmission of the plurality of guide rods 3, and the outer skin of the cable end is cut in sections by the peeling knives 63 in the plurality of peeling mechanisms 6; when the peeling mechanism 6 rotates to cut the outer skin of the cable, the clamping bracket 104 is always clamped on the outside of the peeling mechanism 6, but the top of the clamping bracket 104 is in an open state and will not interfere with the rotation of the peeling mechanism 6; after the cutting is completed, the multi-stage electric telescopic rod 11 is started to drive the plurality of telescopic sleeves 101 in the stepped telescopic mechanism 10 to extend, and the stepped telescopic mechanism The multiple telescopic sleeves 101 in 10 are in a movable suit state, and a positioning ring 102 is provided at the end. When the multi-stage electric telescopic rod 11 pulls the front-end telescopic sleeve 101 into place, it will drive the subsequent telescopic sleeves 101 to move in sequence, so that the multiple telescopic sleeves 101 are extended in a step-by-step manner. When the telescopic sleeves 101 move, they are driven by the clamping bracket 104, so that the multiple peeling mechanisms 6 can move from the head end in sequence, and the peeling knives 63 in the multiple peeling mechanisms 6 push the segmented circumferential sheath to move step by step, so as to avoid the multi-stage electric telescopic rod 11 from being damaged by too much force per unit time, and realize the automatic peeling of the cable end sheath after circumcision.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
