Description

Technical Field

[0001] This application relates to the field of power grid operation equipment technology, specifically to a cable end stripping device and its stripping method. Background Technology

[0002] The connection of distribution network lead-in lines is a crucial link in ensuring power supply to the distribution network, and the operation scenarios are significantly complex and diverse. In terms of site conditions, the work areas are spread across urban built-up areas, towns and villages, industrial parks, and suburban farmland. In urban areas, it is necessary to avoid dense pedestrians and vehicles; in suburban and farmland areas, there are obstacles such as soft ground, ditches, and weeds; and in industrial parks, there is the problem of factory buildings and equipment obstructing the view. Different sites place stringent requirements on the flexibility and adaptability of the work equipment. Regarding the tower environment, the main types are 10-15 meter high cement poles commonly used in 10KV distribution networks, with some using lightweight steel pipe towers. Crossarms are set at a height of 6-10 meters. Older towers pose risks such as weathering and corrosion, and are often surrounded by obstacles such as trees, billboards, and communication lines. In urban areas, some towers are adjacent to buildings, significantly limiting the working space. The condition of the drain wires is divided into two categories: newly built and old ones that have been renovated. New drain wires are copper or aluminum core insulated wires with a cross-section of 25-120mm². Old drain wires have defects such as insulation aging, cracking, and wire oxidation. In addition, the drain wires are hung at an angle of 30-60° with the main line, and the tension conditions vary.

[0003] Currently, there are still many technical bottlenecks in the stripping of the ends of distribution network lead-in lines. Traditional operations rely heavily on manual labor, requiring the use of insulated bucket trucks for high-altitude work. This is subject to significant site constraints, low efficiency, high labor intensity, and safety risks such as falls and electric shock. Existing automated stripping devices have significant compatibility defects. Most devices have fixed inlet structures, unable to flexibly adjust to different wire diameters of 25-120mm², and are incompatible with the different insulation states of newly built and old lead-in lines. Some devices have insufficient stability in their clamping structures, which can easily lead to cable twisting and shifting in the swaying environment of high-altitude tower work, resulting in uncontrolled stripping accuracy and even damage to the wire core. In addition, most existing devices are closed-end inlet designs, which cannot adapt to the radial mounting characteristics of lead-in lines, making it difficult to meet the needs of remote automated robotic operations. Furthermore, they lack effective buffering and compensation mechanisms. In live-line working scenarios, fluctuations in cutting force can easily lead to incomplete insulation stripping or wire core damage, seriously affecting the quality of connection work and power supply reliability. These issues make it difficult for existing technologies to adapt to complex and diverse power distribution network operation scenarios, thus hindering the improvement of efficiency and safety in power distribution network lead wire connection operations. Summary of the Invention

[0004] The purpose of this application is to provide a cable end stripping device and its stripping method to meet the requirements of efficient, stable and fully automatic stripping for live-line working robots in power distribution networks.

[0005] In a first aspect, embodiments of this application provide a cable end stripping device, comprising:

[0014] In some embodiments, the clamping unit includes a toothed claw, which is slidably disposed on the fixed clamping base. The toothed claw has a fixed clamping opening facing the cable side, and the inner wall of the fixed clamping opening has a toothed structure. The extending direction of the toothed structure is perpendicular to the axial direction of the cable to be stripped.

[0015] In some embodiments, the rotary cutting drive assembly includes a C-shaped frame, an annular transmission component, a rotary cutting mounting base, and a third drive source. The C-shaped frame is fixedly mounted on a sliding base, and the axis of the C-shaped frame is coaxial with the clamping center of the fixed clamping assembly, and has a lateral opening for the radial entry of the cable. The rotary cutting mounting base is rotatably mounted on the C-shaped frame, and the annular transmission component is fixedly mounted on the C-shaped frame. Both the annular transmission component and the rotary cutting mounting base have clearance notches corresponding to the positions of the lateral openings. The third drive source is mounted on the rotary cutting mounting base, and the output end of the third drive source is in transmission cooperation with the annular transmission component to drive the rotary cutting mounting base to move circumferentially along the annular transmission component. The guide clamping assembly and the cutting edge assembly are both fixedly mounted on the rotary cutting mounting base.

[0016] In some embodiments, the cutting edge assembly includes a tool holder and a cutting blade; the tool holder is fixed to a rotary cutting mounting base, and the cutting blade is adjustablely mounted on the tool holder along the radial position of the clamping hole, with the cutting edge facing the central axis of the C-shaped frame.

[0017] In some embodiments, an axial guiding mechanism and a displacement compensation assembly are provided between the sliding seat and the fixed seat; the axial guiding mechanism includes a guide rod fixed on the sliding seat and a guide sleeve fixed on the fixed seat, the guide rod and the guide sleeve are slidably engaged, and the extension direction of the guide rod is parallel to the axial direction of the cable to be stripped; the displacement compensation assembly includes a fourth drive source and a displacement screw, the fourth drive source is mounted on the fixed seat through a floating buffer mechanism, the displacement screw is arranged along the axial direction of the cable to be stripped and is threadedly connected to the fourth drive source, and the end of the displacement screw is fixedly connected to the sliding seat to drive the sliding seat to move axially.

[0018] In some embodiments, the floating buffer mechanism includes at least two parallel buffer rods, a buffer plate, a buffer element, and a limiting plate. The buffer rods are fixed to a fixed base along the axial direction of the displacement screw. The buffer plate is slidably sleeved on the buffer rods, with its two ends abutting against the buffer plate and the fixed base, respectively. The fourth drive source is fixedly installed on the side of the buffer plate facing the sliding base. The limiting plate is fixed to the end of the buffer rod away from the fixed base to limit the maximum sliding stroke of the buffer plate.

[0019] Secondly, this application provides a cable end stripping method, implemented based on the aforementioned cable end stripping device, comprising the following steps:

[0020] S1 device positioning: Position the end of the cable to be stripped relative to the preset stripping position, and adjust the posture of the stripping device to make the guide clamping component, the fixed clamping component and the cable coaxial;

[0021] S2 segmented clamping: The drive guide clamping component clamps the end of the cable, and the drive fixed clamping component clamps the inner part of the cable. The distance between the inner clamping position and the end clamping position is greater than or equal to the preset stripping stroke.

[0022] S3 Rotary Cutting Feed: Start the rotary cutting drive assembly, which drives the guide clamping assembly and the cutting blade assembly to rotate together along the circumference of the cable to be stripped; during the rotation, the threaded guide structure in the clamping groove of the guide clamping assembly drives the cutting blade assembly to generate a helical feed motion along the cable axis, and the cutting blade assembly peels off the insulation layer of the cable layer by layer.

[0023] S4 Reset and Unloading: After peeling is completed, the rotary cutting drive assembly stops running, the guide clamping assembly and the fixed clamping assembly release the cable, and the device exits the working position.

[0024] In some embodiments, step S3, the rotary cutting feed process, further includes:

[0025] S31 Real-time calculation of feed rate difference: During the pre-set rotary cutting process, the axial feed rate generated by the threaded guide structure of the guide clamping assembly driving the cutting edge assembly is V0, and the initial axial feed rate of the fourth drive source is V1. The speed difference between the two is calculated in real time as ∆Vi=V0-V1.

[0026] S32 Adaptive Feed and Buffer: The fourth drive source drives the sliding seat to move along the axial guide mechanism at an initial speed V1, and simultaneously drives the cutting edge assembly to feed along the cable axis; the speed difference ∆Vi causes the buffer plate to generate axial displacement along the buffer rod, and the buffer component undergoes elastic deformation simultaneously to offset the instantaneous hard impact caused by the speed difference and maintain the cutting force of the cutting edge assembly constant.

[0027] S33 Limit Triggering Rapid Compensation: When the buffer plate slides to the first limit position, the fourth drive source switches to rapid compensation speed V11, driving the buffer plate to perform rapid displacement compensation to the second limit position. The compensation time T1 = △L1 / V11, where △L1 is the sliding distance between the first limit position and the second limit position.

[0028] S34 Cyclic feed until stripping is completed: When the buffer plate slides to the second limit position, the single displacement compensation is completed, the fourth drive source resumes the initial feed speed V1 and continues to run, repeating the cycle of steps S32 to S33 until the cable insulation layer of the preset stripping stroke △L is stripped.

[0029] The beneficial effects of this application are as follows: This invention achieves stable segmented clamping of cables through coaxially arranged fixed clamping components and guide clamping components, effectively resisting torsional forces during the slicing process, preventing cable twisting and shaking, and improving the stability of the stripping operation. The guide clamping component has a threaded guide structure, which can form a helical compound feed during rotation, achieving smooth cutting without additional axial drive, resulting in higher stripping quality. The rotatable cutting mechanism and open frame structure facilitate radial cable entry, adapting to automated robotic high-altitude operations without manual intervention. The sliding seat and displacement compensation component work together to achieve adaptive adjustment of the axial feed speed, and the floating buffer mechanism can offset the impact caused by speed differences, protecting the wire core from damage, and ensuring uniform and stable cutting force. The overall device has a compact structure and precise operation, adapting to the stripping needs of cables of various diameters, significantly improving the automation level of live-line work in power distribution networks, reducing the risks of high-altitude operations, and improving work efficiency and safety.

[0042] Example 1

[0043] Reference Figure 1 and Figure 4 This application provides a cable end stripping device, which is suitable for stripping the insulation layer of 10kV distribution network insulated cables. The cable end stripping device adopts a modular mechanical structure assembly, and the device as a whole relies on fixed connection, sliding connection and transmission connection to realize the cooperative operation of each component.

[0044] Reference Figure 1 and Figure 2 The cable end stripping device includes a fixed base 1, a fixed clamping assembly 11, a sliding base 2, a guide clamping assembly 3, and a cutting mechanism 4. The fixed base 1 is the bottom load-bearing component of the cable end stripping device. The fixed base 1 is made of rigid metal sheet. The fixed base 1 includes a connecting seat for fastening to the end effector of an external robotic arm, and a fixing plate for providing a mounting carrier for the fixed clamping assembly 11, the sliding base 2, the axial guide mechanism 6, and the displacement compensation assembly 7. The fixing plate is perpendicular to the axis of the cable to be stripped. The structural strength of the fixed base 1 can withstand the axial force and circumferential torsional force generated during the stripping operation.

[0045] Reference Figures 4 to 6The fixing clamping component 11 is installed on the side wall of the fixing base 1 by bolt fastening. The fixing clamping component 11 is used to clamp and fix the non-stripped section of the cable to be stripped. The clamping center of the fixing clamping component 11 is coaxial with the central axis of the cable to be stripped. The fixing clamping component 11 maintains the clamping state throughout the entire stripping operation cycle. The fixing clamping component 11 can resist the circumferential torsional force generated by the rotary cutting action, and prevent the cable to be stripped from rotating circumferentially or moving axially during the stripping process. The clamping force of the fixing clamping component 11 can be adapted to cables of different wire diameters. The clamping contact surface of the fixing clamping component 11 is provided with an anti-slip structure to improve the stability of the clamping process.

[0046] The sliding seat 2 is made of rigid metal sheet. The sliding seat 2 is slidably mounted on the fixed seat 1 along the axial direction of the cable to be stripped and forms a sliding fit connection with the axial guide mechanism 6. It is used to support the cutting mechanism 4 and the guide clamping assembly 3. The sliding seat 2 can slide linearly back and forth along the axial direction of the cable to be stripped. The sliding stroke of the sliding seat 2 matches the preset stripping stroke of the cable to be stripped. The C-shaped frame 411 of the cutting mechanism 4 is fastened to the side wall of the sliding seat 2 by bolts. The sliding seat 2 achieves axial movement under the driving action of the displacement compensation assembly 7. During the movement, the sliding seat 2 always maintains a coaxial state with the cable to be stripped. The structure of the sliding seat 2 can withstand the vibration and force generated by the rotation of the cutting mechanism 4, ensuring the stability of the sliding seat 2 during the movement process.

[0047] Reference Figure 2 and Figure 3 The guide clamping assembly 3 includes an upper clamping body 31 and a lower clamping body 32 arranged symmetrically, and a first driving part 33 for driving the upper clamping body 31 and the lower clamping body 32 to open and close relative to each other. The upper clamping body 31 and the lower clamping body 32 are formed by symmetrical structure processing. Both the upper clamping body 31 and the lower clamping body 32 are made of rigid insulating material. The upper clamping body 31 and the lower clamping body 32 move in a straight line along the radial direction of the cable to be stripped. The upper clamping body 31 and the lower clamping body 32 are both machined with clamping grooves 34 on opposite sides. The cross-section of the clamping grooves 34 is arc-shaped. After the two clamping grooves 34 are closed, they form a clamping hole 35 coaxial with the cable to be stripped. The inner diameter of the clamping hole 35 is adapted to the outer diameter of the cable to be stripped. The clamping center of the guide clamping component 3 is coaxial with the clamping center of the fixed clamping component 11. The guide clamping component 3 is used to clamp and fix the end stripping section of the cable to be stripped. The guide clamping component 3 can rotate synchronously with the cutting mechanism 4. During the rotation of the guide clamping component 3, the cable to be stripped is maintained in a clamping state.

[0048] Reference Figure 3The inner wall of the clamping groove 34 is integrally formed with multiple guide bars 36 arranged at equal intervals. Each guide bar 36 is distributed at a preset angle with the axis of the clamping hole 35. The arrangement of the multiple guide bars 36 forms a threaded guide structure. When the guide clamping assembly 3 rotates circumferentially, the threaded guide structure can drive the guide clamping assembly 3 and the cutting blade assembly 42 to make a spiral feeding motion along the axis of the cable to be stripped. The number of guide bars 36 and the preset angle are set according to the wire diameter and insulation layer thickness of the cable to be stripped. The surface of the guide bars 36 is smoothed to reduce the frictional resistance between the guide bars 36 and the surface of the cable to be stripped.

[0049] Reference Figure 2 The first drive unit 33 includes a first forward and reverse lead screw 331 and a first drive source 332. The first forward and reverse lead screw 331 is made of metal lead screw. The rod body of the first forward and reverse lead screw 331 is provided with a forward thread section and a reverse thread section with opposite directions of rotation. The first forward and reverse lead screw 331 is rotatably mounted on the mounting base of the guide clamping assembly 3. The two ends of the first forward and reverse lead screw 331 are rotatably connected to the mounting base through bearings. The upper clamping body 31 and the lower clamping body 32 are respectively connected to the forward thread section and the reverse thread section of the first positive and negative lead screw 331 to form a threaded transmission connection. The first drive source 332 uses a drive motor as the power output component. The output shaft of the first drive source 332 is connected to one end of the first positive and negative lead screw 331 through a coupling. When the first drive source 332 is running, it drives the first positive and negative lead screw 331 to rotate. When the first positive and negative lead screw 331 rotates, it drives the upper clamping body 31 and the lower clamping body 32 to move in opposite directions or in opposite directions along the radial direction of the cable to be stripped. The opposite movement realizes the mold closing and clamping action of the guide clamping component 3, and the opposite movement realizes the mold opening and clamping action of the guide clamping component 3. The operating speed of the first drive source 332 can be adjusted according to the operation requirements. The thread accuracy of the first positive and negative lead screw 331 ensures the synchronicity of the opening and closing movements of the upper clamping body 31 and the lower clamping body 32.

[0050] Reference Figures 4 to 6The fixed clamping assembly 11 includes a fixed clamping base 5, a clamping drive unit 51, and two sets of clamping units 52. The fixed clamping base 5 is made of a rigid metal frame structure and is fixedly installed on the upper surface of the fixed base 1 by bolt fastening. The fixed clamping base 5 is used to support the clamping drive unit 51 and the two sets of clamping units 52. The frame structure of the fixed clamping base 5 ensures the rigidity and stability of the overall component. The clamping drive unit 51 includes a second drive source 511 and a second forward and reverse screw 512. The second drive source 511 is mounted on the fixed base 1 by bolt fastening. The second drive source 511 uses a drive motor as the power output component. The output shaft of the second drive source 511 is connected to one end of the second forward and reverse screw 512 through a coupling. The second forward and reverse screw 512 is rotatably mounted inside the fixed clamping base 5. The two ends of the second forward and reverse screw 512 are rotatably connected to the fixed clamping base 5 through bearings. The rod body of the second forward and reverse screw 512 is provided with a forward thread section and a reverse thread section with opposite directions of rotation. The two sets of clamping units 52 are respectively connected to the forward thread section and the reverse thread section of the second forward and reverse screw 512 to form a threaded transmission engagement. The two sets of clamping units 52 are symmetrically distributed along the axis of the second forward and reverse screw 512. When the second drive source 511 is running, it drives the second forward and reverse screw 512 to rotate. When the second forward and reverse screw 512 rotates, it drives the two sets of clamping units 52 to move towards each other or away from each other along the radial direction of the cable to be stripped. The movement towards each other realizes the clamping action of the fixed clamping component 11, and the movement away from each other realizes the loosening action of the fixed clamping component 11.

[0051] The clamping unit 52 includes a toothed claw 521. The toothed claw 521 has a fixed clamping opening 522 machined on the side facing the cable. The fixed clamping opening 522 has a V-shaped cross-section. The size of the fixed clamping opening 522 is adapted to the wire diameter of the cable to be stripped. The inner wall of the fixed clamping opening 522 is integrally formed with a toothed structure 523. The extension direction of the toothed structure 523 is perpendicular to the axial direction of the cable to be stripped. The toothed structure 523 can increase the friction between the toothed claw 521 and the surface of the cable to be stripped, preventing the cable to be stripped from sliding axially or rotating circumferentially in the clamping state. The toothed claw 521 is made of rigid metal material, and the structural strength of the toothed claw 521 meets the force requirements of the clamping operation.

[0052] In some embodiments, the system further includes a sliding base, a sliding guide rod, and an elastic element. The sliding guide rod is fixedly connected to the back of the toothed claw 521 and slidably disposed on the sliding base. The toothed claw 521 can slide linearly along the length of the sliding guide rail. The elastic element is sleeved on the sliding guide rod to drive the toothed claw 521 to slide towards the side that is close to each other.

[0053] The cutting mechanism 4 is used to perform rotary cutting and stripping operations on the insulation layer of the cable to be stripped. The cutting mechanism 4 includes a rotary cutting drive assembly 41 and a cutting edge assembly 42. The rotary cutting drive assembly 41 is connected to the guide clamping assembly 3. The rotary cutting drive assembly 41 is used to output circumferential rotational power. When the rotary cutting drive assembly 41 is running, it drives the guide clamping assembly 3 and the cutting edge assembly 42 to rotate together along the circumference of the cable to be stripped. The cutting edge assembly 42 is used to directly contact and strip the insulation layer of the cable to be stripped. The cutting depth of the cutting edge assembly 42 can be adjusted according to the thickness of the insulation layer of the cable to be stripped. The entire cutting mechanism 4 moves along the axial direction of the cable to be stripped with the sliding seat 2. The rotation center of the cutting mechanism 4 is coaxial with the central axis of the cable to be stripped.

[0054] Reference Figure 1 and Figure 2 In some embodiments, the rotary cutting drive assembly 41 includes a C-shaped frame 411, an annular transmission component 412, a rotary cutting mounting base 413, and a third drive source 414. The C-shaped frame 411 is made of rigid metal sheet by bending. The C-shaped frame 411 is fixedly installed on the upper surface of the sliding seat 2 by bolt fastening. The axis of the C-shaped frame 411 is coaxial with the clamping center of the fixed clamping assembly 11. The side of the C-shaped frame 411 is machined with a lateral opening for the radial entry of the cable. The width of the lateral opening is greater than the maximum outer diameter of the cable to be stripped. The cable to be stripped can enter the inner center position of the C-shaped frame 411 through the lateral opening. The rotary cutting mounting base 413 is mounted on the C-shaped frame 411. In this embodiment, the guide clamping assembly 3 is installed on the side of the rotary cutting mounting base 413 away from the fixed clamping assembly 11. The rotary cutting mounting base 413 is a metal housing component. The rotary cutting mounting base 413 is provided with a circumferential guide portion adapted to the C-shaped frame 411. The rotary cutting mounting base 413 can rotate 360 ​​degrees around the circumference of the C-shaped frame 411. The rotation center of the rotary cutting mounting base 413 is coaxial with the axis of the C-shaped frame 411. The annular transmission component 412 is fixedly installed on the side wall of the C-shaped frame 411 by bolt fastening. The annular transmission component 412 is made of an annular external gear ring structure. Both the annular transmission component 412 and the rotary cutting mounting base 413 are machined with clearance notches corresponding to the positions of the side openings. The size of the clearance notches is adapted to the size of the side openings. The clearance notches are used to allow the cables to be stripped to pass radially.

[0055] In some embodiments, the third drive source 414 is mounted on the surface of the rotary cutting mounting base 413 by bolt fastening. The third drive source 414 uses a drive motor as a power output component and also includes a drive gear, a driven gear, and a transmission belt. The drive gear and the driven gear are rotatably mounted on the surface of the rotary cutting mounting base 413 via bearings. The axis of the drive gear is coaxial with the output axis of the third drive source 414. The drive gear is fixedly mounted on the output end of the third drive source 414. The driven gear is symmetrically distributed on the surface of the rotary cutting mounting base 413 with respect to the drive gear. A first pulley is coaxially fixed on one side of the drive gear, and a second pulley is coaxially fixed on one side of the driven gear. The transmission belt is wrapped around the outside of the first pulley and the second pulley, and the transmission belt forms a friction transmission connection with the first pulley and the second pulley, respectively. The tooth profile parameters of the driving gear and the driven gear are consistent. Both the driving gear and the driven gear form a meshing transmission connection with the inner tooth profile structure of the annular transmission component 412. The driving gear and the driven gear are distributed circumferentially along the rotary cutting mounting base 413. The straight distance between the driving gear and the driven gear is greater than the size of the clearance notch on the annular transmission component 412. During the rotation of the rotary cutting mounting base 413, one of the gears is always in a meshing transmission state with the annular transmission component 412, while the other gear can cross the clearance notch area. This avoids the transmission interruption during the rotation of the rotary cutting mounting base 413, ensuring that the power transmitted by the third drive source 414 continuously acts on the rotary cutting mounting base 413, so that the rotary cutting mounting base 413 maintains a continuous and stable rotational motion along the circumferential direction of the annular transmission component 412, providing a continuous power input for the circumferential rotary cutting action of the guide clamping assembly 3 and the cutting edge assembly 42.

[0056] Reference Figure 2 The cutting edge assembly 42 includes a tool holder 421 and a cutting insert 422. The tool holder 421 is machined from a rigid metal block. The tool holder 421 is fixed to the upper half clamp 31 and the lower half clamp 32 of the guide clamping assembly 3 or to the surface of the rotary cutting mounting base 413 by bolt fastening. The tool holder 421 is used to support the cutting insert 422. The tool holder 421 is provided with a radial adjustment structure inside. The cutting blade 422 is radially mounted inside the tool holder 421 along the clamping hole 35. The cutting blade 422 is made of cemented carbide. The cutting edge of the cutting blade 422 is set towards the central axis of the C-shaped frame 411. The cutting edge angle of the cutting blade 422 is adapted to the cutting requirements of the insulation layer of the cable to be stripped. By adjusting the radial position of the cutting blade 422 inside the tool holder 421, the cutting depth of the cutting blade 422 can be adjusted to adapt to cables with different insulation layer thicknesses. The installation angle of the cutting blade 422 remains fixed, and the cutting edge of the cutting blade 422 maintains stable contact with the insulation layer of the cable to be stripped during rotation.

[0057] An axial guide mechanism 6 and a displacement compensation component 7 are provided between the sliding seat 2 and the fixed seat 1. The axial guide mechanism 6 is used to provide guide support for the axial sliding of the sliding seat 2, and the displacement compensation component 7 is used to provide power for the axial movement of the sliding seat 2. The displacement compensation component 7 can adjust the axial movement speed of the sliding seat 2 to match the spiral feed speed of the cutting mechanism 4.

[0058] Specifically, refer to Figure 4 and Figure 5 In this embodiment, the axial guiding mechanism 6 includes a guide rod 61 fixed on the sliding seat 2 and a guide sleeve 62 fixed on the fixed seat 1. The sliding seat 2 includes two triangular plates that are symmetrically arranged and adapted to the shape of the fixed seat 1. The guide rod 61 is fixedly connected between the two plates to form a whole. The guide rod 61 is made of metal round rod and is set to three sets. The three sets of guide rods 61 are evenly spaced circumferentially along the triangle of the sliding seat 2. The guide sleeve 62 is made of metal sleeve and is fixedly connected to the fixed seat 1. The guide rod 61 and the guide sleeve 62 form a sliding fit. The guide rod 61 can slide linearly along the inner wall of the guide sleeve 62. The extension direction of the guide rod 61 is parallel to the axial direction of the cable to be stripped. The fit clearance between the guide rod 61 and the guide sleeve 62 is precision machined to ensure the smoothness of the sliding process of the sliding seat 2 and to avoid radial shaking of the sliding seat 2.

[0059] Reference Figure 4 and Figure 5 The displacement compensation component 7 includes a fourth drive source 71 and a displacement screw 72. The fourth drive source 71 is mounted on the upper surface of the fixed base 1 via a floating buffer mechanism 73. The fourth drive source 71 uses a dynamically adjustable screw motor as its power output component, and its operating speed can be dynamically adjusted according to operational requirements. The displacement screw 72 is made of metal screw and is arranged along the axial direction of the cable to be stripped. The displacement screw 72 is connected to the output end of the fourth drive source 71 via a threaded drive. The end of the displacement screw 72 is fixedly connected to the sliding seat 2 via a flange. When the fourth drive source 71 operates, it drives the displacement screw 72 to move axially. When the displacement screw 72 moves, it drives the sliding seat 2 to move linearly along the axial guide mechanism 6, thereby realizing the axial feed of the cutting mechanism 4.

[0060] The floating buffer mechanism 73 includes at least two parallel buffer rods 731, a buffer plate 732, a buffer element 733, and a limiting plate 734. The number of buffer rods 731 is set to two, and the two buffer rods 731 are distributed parallel to each other along the axial direction of the displacement screw 72. The buffer rods 731 are made of round metal rods, and one end of each buffer rod 731 is fixedly connected to the fixed seat 1. The extension direction of the buffer rods 731 is consistent with the axial direction of the displacement screw 72. The buffer plate 732 is made of sheet metal and is slidably fitted onto the outer wall of the buffer rods 731. The buffer plate 732 can slide linearly along the length of the buffer rods 731. The buffer element 733 is made of compression spring and is sleeved on the outer wall of the buffer rod 731. Both ends of the buffer element 733 abut against the buffer plate 732 and the fixed seat 1, respectively. The buffer element 733 undergoes elastic deformation when the buffer plate 732 slides. The buffer element 733 is used to counteract the instantaneous hard impact caused by the difference in feed speed between the displacement compensation component 7 and the cutting mechanism 4, maintaining a constant cutting force on the cutting edge assembly 42. The fourth drive source 71 is fixedly installed on the side of the buffer plate 732 facing the sliding seat 2 by bolt fastening. The fourth drive source 71 slides synchronously with the buffer plate 732. The limiting plate 734 is made of sheet metal and is fixed to the end of the buffer rod 731 away from the fixed seat 1 by bolt fastening. The limiting plate 734 is used to limit the maximum sliding stroke of the buffer plate 732, preventing the buffer plate 732 from sliding out of the buffer rod 731 and avoiding excessive deformation and damage to the buffer element 733.

[0061] In some embodiments, both the first drive source 332 and the second drive source 511 can be stepper motors as power output components, and the output shaft of the stepper motor is connected to the lead screw via a coupling.

[0062] Example 2

[0063] Secondly, referring to Figure 7 This application provides a method for stripping the insulation from the end of a cable. The method is based on the aforementioned cable end stripping device and is applied to live-line work scenarios for insulated cables in power distribution networks. The method sequentially executes the steps of device positioning, segmented clamping, rotary cutting and feeding, and resetting and unloading according to the work process. Each step is interconnected to complete the stripping of the insulation layer from the end of the cable to be stripped.

[0064] S1 Device Positioning: The device positioning step is used to move the cable end stripping device to the working position of the cable to be stripped, locate the end position of the cable to be stripped and the preset stripping position, and drive the cable end stripping device to complete the spatial position adjustment through the external robotic arm. Adjust the posture of the stripping device so that the clamping center of the guide clamping component and the clamping center of the fixed clamping component are coaxial with the central axis of the cable to be stripped. During the device positioning process, ensure that there is no structural interference between the cable end stripping device and the cable to be stripped. After the device is positioned, keep the position of the cable end stripping device stable.

[0065] S2 Segmented Clamping: The segmented clamping step is used to fix the cable to be stripped in segments. The first drive source of the guide clamping assembly is driven to rotate, which drives the first positive and negative screws to rotate. The first positive and negative screws drive the upper and lower clamping bodies to complete the mold closing action, clamping the end of the cable. The clamping holes of the guide clamping assembly form a tight fit with the outer wall of the cable to be stripped. The second drive source of the fixed clamping assembly is driven to rotate, which drives the second positive and negative screws to rotate. The second positive and negative screws drive the two sets of clamping units to complete the opposite movement, clamping the inner part of the cable. The distance between the inner clamping position and the end clamping position is greater than or equal to the preset stripping stroke, which is the length of the insulation layer to be stripped. After the segmented clamping is completed, both the guide clamping assembly and the fixed clamping assembly maintain the clamping state. The fixed clamping assembly resists the torsional force generated by the rotary cutting operation.

[0066] S3 Rotary Cutting Feed: The rotary cutting feed step is used to perform the stripping of the cable insulation layer. The third drive source of the rotary cutting drive assembly is activated, engaging with the ring transmission component to drive the rotary cutting mounting base to rotate circumferentially along the C-shaped frame. The rotary cutting mounting base drives the guide clamping assembly and the cutting blade assembly to rotate circumferentially along the cable to be stripped. During rotation, the threaded guide structure in the clamping groove of the guide clamping assembly engages with the surface of the cable to be stripped, driving the cutting blade assembly to generate a helical feed motion along the cable axis. The cutting edge of the cutting blade assembly contacts the insulation layer of the cable to be stripped, peeling off the insulation layer layer by layer. The rotary cutting feed speed is adjusted according to the insulation layer thickness and wire diameter of the cable to be stripped, maintaining a stable cutting depth of the cutting blade assembly during the rotary cutting feed process.

[0067] S4 Reset and Unloading: The reset and unloading step is used to reset the device after the stripping operation. After stripping, the third drive source of the rotary cutting drive assembly stops operating, and the guide clamping assembly and cutting blade assembly stop their circumferential rotation. The first drive source of the guide clamping assembly reverses its rotation, and the upper and lower clamping bodies complete the mold opening action, releasing the cable end. The second drive source of the fixed clamping assembly reverses its rotation, and the two clamping units complete the opposite movement, releasing the inner part of the cable. The external robotic arm drives the cable end stripping device to move and exit the working position, completing the entire stripping operation process.

[0068] In some embodiments, the annular transmission component is manufactured using a synchronous toothed belt structure. The synchronous toothed belt is fixedly installed on the inner side wall of the C-shaped frame. A synchronous pulley is provided at the output end of the third drive source. The synchronous pulley and the synchronous toothed belt form a meshing transmission, driving the rotary cutting mounting base to perform circumferential rotation.

[0069] Step S3, the rotary cutting feed process, also includes feed rate difference calculation, adaptive feed and buffering, limit triggering rapid compensation, and cyclic feed steps. Each step is executed synchronously with the rotary cutting feed step to achieve adaptive compensation of axial feed.

[0070] S31 calculates the feed rate difference in real time: During the pre-set rotary cutting process, the axial feed rate V0 generated by the threaded guide structure of the guide clamping assembly driving the cutting edge assembly is determined by the guide bar angle of the threaded guide structure and the rotary cutting speed. The initial axial feed rate of the fourth drive source of the displacement compensation assembly is V1, which is the pre-set initial feed rate. The speed difference ∆Vi between the two is calculated in real time by the control module. The formula for calculating the speed difference is ∆Vi = V0 - V1. The speed difference reflects the degree of speed matching between the helical feed of the cutting mechanism and the axial push of the displacement compensation assembly. When the speed difference is zero, the feed rates are perfectly matched, and no compensation action is required.

[0071] S32 Adaptive Feed and Buffer: The fourth drive source operates at an initial speed V1, driving the displacement screw to move. The displacement screw drives the sliding seat to move along the axial guide mechanism, simultaneously driving the cutting edge assembly to feed along the cable axis. The speed difference ∆Vi causes the buffer plate to move axially along the buffer rod. When the buffer plate slides, it compresses or stretches the buffer component, causing the buffer component to undergo elastic deformation simultaneously. The elastic deformation of the buffer component offsets the instantaneous hard impact caused by the speed difference. The elastic force of the buffer component adjusts the axial feed force of the cutting edge assembly, maintaining a constant cutting force and preventing excessive cutting force from damaging the wire core or insufficient cutting force from failing to peel off the insulation layer.

[0072] S33 Limit Triggering Fast Compensation: When the buffer plate slides along the buffer rod to the first limit position, the first limit position is the preset detection position on the buffer rod. The fourth drive source receives the position signal and switches to the fast compensation speed V11. The value of the fast compensation speed V11 is greater than the initial speed V1. The fourth drive source drives the buffer plate to perform a fast displacement compensation movement. The buffer plate moves along the buffer rod to the second limit position. The calculation formula for the compensation time T1 is T1=△L1 / V11, where △L1 is the sliding distance between the first limit position and the second limit position. The value of △L1 is set according to the stroke of the floating buffer mechanism. During the fast compensation process, the displacement deviation caused by the speed difference is quickly eliminated.

[0073] S34 Cyclic Feeding until Stripping is Complete: When the buffer plate slides to the second limit position, which is another preset detection position on the buffer rod, a single displacement compensation is completed. The fourth drive source receives the position signal and resumes operation at the initial feed speed V1. The adaptive feed and buffering, limit triggering rapid compensation steps are repeated to continuously compensate and adjust the axial feed speed until the sliding seat completes the preset stripping stroke △L and the cutting edge assembly completes the cable insulation stripping operation of the preset stripping stroke △L.

[0074] In some embodiments, the axial guide mechanism adopts a linear guide rail and slider cooperation structure. The linear guide rail is fixed on the upper surface of the fixed seat, and the slider is fixed on the bottom of the sliding seat. The slider and the linear guide rail form a sliding cooperation to provide guidance support for the axial movement of the sliding seat.

[0075] The cable end stripping device and method disclosed in this application utilize a coaxial segmented clamping configuration of a fixed clamping component and a guide clamping component to stably fix the cable to be stripped, limiting circumferential torsion during the cutting process and improving the stability of the stripping operation. The threaded guide structure inside the guide clamping component allows the cutting edge assembly to complete axial helical feeding while rotating circumferentially, simplifying the device's transmission structure and improving the continuity of the feeding action. The axial guide mechanism, in conjunction with the displacement compensation component, enables smooth axial movement of the sliding seat, while the floating buffer mechanism counteracts the impact caused by differences in feed speed, maintaining a constant cutting force and preventing damage to the cable core from the cutting edge assembly. The open C-shaped frame and clearance notch structure facilitate radial entry of the cable to be stripped into the device, adapting to automated operation scenarios. The device has a compact overall structure, stable connections between components, and is suitable for stripping cables of different diameters and insulation thicknesses. It offers high stripping accuracy and efficiency, and has a long service life.
