Description

Technical Field

[0001] This invention relates to the field of electrical tools, and more specifically, to an electric wire stripper. Background Technology

[0002] Currently, electricians in the power industry frequently perform wiring work, which often involves wire stripping—removing the insulation from the ends of electrical wires. Scenarios frequently arise when splicing conductors, and this process requires stripping a sufficient length of the conductor's insulation before the conductive core can be effectively connected. Traditional wire stripping tools are manual wire strippers, requiring the operator to manually apply force to close the jaws and cut and strip the insulation. This demands a high level of skill from the operator. For electricians, prolonged work with many splices can easily lead to hand fatigue, and the low stripping efficiency makes it difficult to meet the needs of large-scale or high-efficiency wiring work. Therefore, there is an urgent need for a labor-saving and easy-to-operate electric wire stripper to improve wire stripping efficiency. Summary of the Invention

[0003] To address the problems existing in the prior art, this solution proposes an electric wire stripper that, through the cooperation of a support component, a clamping component, a stripping component, and a drive component, achieves automatic stripping of the wire insulation layer, thus solving the problems of the prior art.

[0004] To achieve the above objectives, the technical solution provided by the present invention is as follows: An electric wire stripper, comprising Support components; A clamping assembly, disposed on the support assembly, has an openable and closable clamping jaw for clamping wires; A wire stripping assembly, disposed on the support assembly, includes a cutting tool system configured to cut the wire insulation layer extending from the clamping jaws and pull the cut wire insulation layer away from the wire core to achieve stripping. A drive assembly for driving the opening and closing of the clamping jaws and / or driving the cutting tool to perform the cutting and peeling action of the insulating layer.

[0005] During operation, the wire with the insulation layer to be stripped is first inserted into the clamping jaws. The drive assembly is then activated, causing the clamping assembly to actuate and firmly hold the non-cutting area of ​​the wire in place. The drive assembly then continues to operate, driving the stripping assembly's cutting tool system to cut the wire insulation layer extending from the clamping jaws and pulling the cut insulation layer away from the wire core to achieve stripping. This application, through the cooperation of the support assembly, clamping assembly, stripping assembly, and drive assembly, allows for automatic insulation stripping simply by inserting the wire into the clamping jaws and starting the device. This convenient operation effectively reduces hand fatigue caused by prolonged operator work and improves stripping efficiency.

[0006] In one embodiment of the electric wire stripper of this application, the clamping assembly further includes a first clamp and a second clamp, wherein the first clamp and the second clamp are disposed opposite to each other in a first direction to form the clamping jaws.

[0007] In one embodiment of the electric wire stripper of this application, the first clamp is fixed to the support assembly, and the second clamp is slidably connected to the support assembly. The drive assembly acts on the second clamp, driving it to move linearly along a predetermined trajectory, thereby opening and closing the clamping jaws by moving closer to or away from the first clamp. In use, the wire is inserted into the clamping jaws between the first and second clamps. Under the drive assembly, the second clamp moves closer to the first clamp, and the clamping jaws continuously narrow until they clamp the insulation layer of the wire in the non-cutting area.

[0008] In one embodiment of the electric wire stripper of this application, the clamping assembly further includes a first limiting block fixed to the support assembly. The first limiting block has a limiting portion that abuts against the second clamp. When the second clamp moves along the sliding path, the limiting portion cooperates with the limiting stop portion of the second clamp to constrain the maximum sliding stroke of the second clamp. The first limiting block can limit the sliding path and sliding stroke of the second clamp, ensuring that the second clamp always reciprocates along the first direction, thereby limiting the size between the clamping jaws of the first and second clamps.

[0009] In one embodiment of the electric wire stripper of this application, the wire stripping assembly further includes a blade holder, the blade system is connected to the blade holder, and the blade holder is adapted to drive the blade system to move in a second direction to strip the insulation layer of the wire.

[0010] In one embodiment of the electric wire stripper of this application, the wire stripping assembly further includes a first return spring, one end of which is connected to the blade holder and the other end of which is connected to the support assembly. The first return spring is configured to drive the blade holder to move in a second direction and then return to its original position.

[0011] In one embodiment of the electric wire stripper of this application, the cutting tool system further includes a first cutting edge and a second cutting edge, the first cutting edge and the second cutting edge being disposed opposite to each other to form a cutting edge; the first cutting edge and the second cutting edge are adapted to cut the wire insulation layer located within the cutting edge. This application provides a tool holder and mounts the cutting tool system on the tool holder. The cutting tool system can move along a first direction to cut the wire insulation layer, and the tool holder can drive the cutting tool system to move along a second direction, thereby enabling the cutting tool system to peel off the wire insulation layer, achieving automatic stripping of the wire insulation layer.

[0012] In one embodiment of the electric wire stripper of this application, the first blade is fixed to the blade holder; the second blade is slidably connected to a first groove in the blade holder; the second blade slides along the first groove to move closer to or further away from the first blade.

[0013] In one embodiment of the electric wire stripper of this application, a second return spring is further fixedly connected to the second blade. The other end of the second return spring is connected to the support assembly; when the second blade slides in the first groove, the second return spring accumulates elastic potential energy to drive the second blade back to its initial position.

[0014] In one embodiment of the electric wire stripper of this application, the wire stripping assembly further includes a second limiting block fixed to the support assembly. The second limiting block has a limiting plane that abuts against the blade holder, restricting the displacement of the blade holder in a first direction. The second limiting block can abut against the side of the blade holder, thereby restricting the displacement of the blade holder in the first direction, so that the blade holder can only move along the second direction.

[0015] In one embodiment of the electric wire stripper of this application, a wire stop block is further connected to the blade holder. The wire stop block, the blade edge, and the clamping jaws are arranged coaxially and located radially outward from the blade edge. This coaxial arrangement allows the wire to be inserted into the clamping jaws and the blade edge. The function of the wire stop block is to abut the end of the wire before it enters, thereby determining the cutting length of the wire insulation layer.

[0016] In one embodiment of the electric wire stripper of this application, the blade holder is further provided with a first sliding post extending in a second direction; the wire stop block is slidably connected to the first sliding post and is configured to slide along the axial direction of the first sliding post to adjust the distance between it and the blade edge.

[0017] In one embodiment of the electric wire stripper of this application, the wire stop block is further provided with an adjustment knob, which is connected to the first slide post and used to lock the position of the wire stop block on the first slide post. The position of the wire stop block can be adjusted by sliding it on the first slide post. After adjustment, the wire stop block is fixed by the adjustment knob, thereby controlling the distance between the wire stop block and the cutting edge, and thus controlling the cutting length of the wire insulation layer.

[0018] In one embodiment of the electric wire stripper of this application, the support assembly further includes a main clamp frame; the main clamp frame has an elongated slot along a first direction; a first mounting platform and a second mounting platform are respectively disposed on both sides of the elongated slot on the main clamp frame; the clamping assembly is assembled on the first mounting platform; the wire stripping assembly is mounted on the second mounting platform; and the drive assembly is mounted in the elongated slot. By providing the first and second mounting platforms on both sides of the elongated slot and placing the drive assembly within the elongated slot, the drive assembly can perform the driving action of closing the clamping jaws in the clamping assembly and closing the blades in the wire stripping assembly during its movement along the elongated slot.

[0019] In one embodiment of the electric wire stripper of this application, the drive assembly further includes a motor and a threaded drive mechanism, wherein the threaded rod of the threaded drive mechanism is coaxially connected to the output shaft of the motor, and the threaded rod is arranged axially within the long slot.

[0020] In one embodiment of the electric wire stripper of this application, the threaded drive mechanism further includes a moving block, the moving block having a threaded hole that engages with the threaded rod; the moving block extends to form a stop portion; the stop portion slides against the inner wall of the long groove; the stop portion and the long groove cooperate to form an anti-rotation pair; the moving block is configured to reciprocate along the axial direction of the threaded rod.

[0021] In one embodiment of the electric wire stripper of this application, a driving block is further fixedly connected to the moving block. The driving block includes a first wing plate slidably connected to the first mounting platform and a second wing plate slidably connected to the second mounting platform. When the driving block moves with the moving block, it can synchronously drive the first and second wing plates to move.

[0022] In one embodiment of the electric wire stripper of this application, the first wing plate is provided with an installation channel, and a compression spring is placed in the installation channel. One end of the compression spring elastically abuts against the pressure-bearing end face of the telescopic rod, and the other end of the telescopic rod is fixedly connected to the clamping assembly.

[0023] In one embodiment of the electric wire stripper of this application, the second wing plate is further connected to the wire stripping assembly via a ramp slide mechanism. The ramp slide mechanism includes: a first wedge block located at one end of the second wing plate; and a second wedge block located at the opposite end of the wire stripping assembly. The mating surfaces of the first and second wedge blocks have an angle α. When the moving block drives the second wing plate, the ramp slide mechanism converts the first directional displacement into a second directional displacement of the wire stripping assembly. When the clamping jaws have not yet fully gripped the wire, the first wing plate pushes a compression spring, which in turn pushes a telescopic rod and a second clamp connected to a clamping assembly at one end of the telescopic rod, causing the clamping jaws to narrow until they fully grip the wire. After the clamping jaws have fully gripped the wire, the compression spring can continue to deform under pressure, allowing the driving block to continue moving forward. This causes the first wedge block at one end of the second wing plate to contact the second wedge block, subsequently pushing the second wedge block to move along the second direction. The second wedge block then drives the wire stripping assembly (blade holder and cutting tool system) connected to it to move along the second direction. By using the inclined plane slide mechanism, the movement of the drive block in the first direction can be converted into the movement of the wire stripping assembly in the second direction. Only one power source is needed to drive the movement in two vertical directions, which helps to simplify the equipment structure and reduce the size of the equipment.

[0024] In an electric wire stripper according to this application, the second cutting edge of the cutting tool system is further positioned on the moving trajectory of the driving block. When the driving block moves along the moving trajectory, it contacts and engages with the bearing surface of the second cutting edge. Responding to the mechanical action of the driving block, the second cutting edge generates a closed displacement stroke towards the first cutting edge. The closed displacement strokes of the first and second cutting edges form a cutting path, which covers the radial cutting area of ​​the wire insulation layer. The second cutting edge cuts the wire insulation layer according to the closed displacement stroke forming the cutting path, and the cutting edge engages at the cut point of the wire insulation layer.

[0025] In one embodiment of the electric wire stripper of this application, the drive assembly further includes a power supply battery and a circuit board. The power supply battery and the circuit board are electrically connected to the motor. The battery supplies power to the circuit board and the motor. The circuit board can adjust the speed and number of rotations of the motor. By controlling the number of rotations, the travel of the moving block and the drive block is controlled, thereby controlling the displacement of the clamping assembly and the wire stripping assembly, ensuring the accuracy of the displacement of the clamping assembly and the wire stripping assembly.

[0026] In one embodiment of the electric wire stripper of this application, the support assembly further includes an ergonomic grip housing with a tool mounting portion at its front end and a holding portion at its rear end; the main clamp is fixed to the tool mounting portion; and the trigger switch of the motor is located in the transition area between the holding portion and the tool mounting portion.

[0027] The beneficial effects of this application are: (1) This application includes a support component, a clamping component, a stripping component, and a drive component. The support component serves as the foundation of the overall structure, providing a platform for the installation and operation of other components. The clamping component is used to firmly hold the wire during the stripping process, preventing displacement during cutting and stripping operations. The stripping component is responsible for precisely cutting and efficiently stripping the insulation layer of the wire; its cutting tool system, through a reasonable structural design, achieves an orderly connection between cutting and stripping actions. The drive component provides power for the entire stripping process, driving the relevant components through a motor, thereby driving the clamping component and the stripping component to complete a series of operational procedures. Through the coordinated operation of the support component, clamping component, stripping component, and drive component, the wire can be directly inserted into the clamping jaws, and the electric stripping of the wire insulation layer can be completed by starting the equipment. This equipment has a simple structure, is easy to operate, and can effectively reduce hand fatigue caused by prolonged operation, improving stripping efficiency.

[0028] (2) The drive assembly involved in this application can smoothly complete the clamping of wires, cutting of insulation layers, and stripping of insulation layers with only a single motor and a threaded drive mechanism that works in conjunction with it. This simple and efficient design effectively reduces the number of motors, thereby reducing the size and weight of the equipment. This design is highly beneficial to the operator; the smaller size and lighter weight reduce operator fatigue when holding the equipment for extended periods, thus improving work efficiency and comfort.

[0032] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments.

[0033] like Figure 1 As shown, this application provides an electric wire stripper, including a support assembly 100, a clamping assembly 200, a stripping assembly 300, and a drive assembly 400. The support assembly 100 serves as a support platform for the entire electric wire stripper and connects the clamping assembly 200, the stripping assembly 300, and the drive assembly 400. The clamping assembly 200 is disposed on the support assembly 100 and has an openable clamping jaw 210 for clamping a wire 500. The clamping assembly 200 clamps the insulation layer 510 of the non-cutting area of ​​the wire 500 and provides clamping force at one end for stripping the insulation layer 510 of the cutting area of ​​the wire 500. The stripping assembly 300 is disposed on the support assembly 100 and includes a cutting tool system 310 configured to cut the wire insulation layer 510 extending from the clamping jaw 210 and pull the cut wire insulation layer 510 away from the wire core 520 to achieve stripping. The drive assembly 400 is used to drive the clamping jaws 210 to open and close and / or drive the cutting tool to perform the cutting and peeling action of the insulating layer 510.

[0034] During operation, the wire 500 with the insulation layer 510 to be stripped is first inserted into the clamping jaws 210. The drive assembly 400 is then activated, causing the clamping assembly 200 to move, and the clamping jaws 210 firmly secure the non-cutting area of ​​the wire 500. Subsequently, the drive assembly 400 continues to operate, driving the cutting tool system 310 of the stripping assembly 300 to cut the wire insulation layer 510 extending from the clamping jaws 210, and pulling the cut insulation layer 510 away from the wire core 520 to achieve stripping. This application, through the cooperation of the support assembly 100, clamping assembly 200, stripping assembly 300, and drive assembly 400, allows for automatic stripping of the wire insulation layer 510 simply by inserting the wire 500 into the clamping jaws 210 and starting the equipment. This convenient operation effectively reduces hand fatigue caused by prolonged operator work and improves stripping efficiency.

[0035] Clamping assembly 200:

[0036] like Figure 2 As shown, in this application, the clamping assembly 200 includes a first caliper 220 and a second caliper 230, which are disposed opposite to each other in a first direction 610 to form a clamping jaw 210. The first caliper 220 is fixed to the support assembly 100, and the second caliper 230 is slidably connected to the support assembly 100. The drive assembly 400 acts on the second caliper 230, driving it to move linearly along a predetermined trajectory, thereby opening and closing the clamping jaw 210 by moving closer to or away from the first caliper 220.

[0037] Specifically, the first caliper 220 is an L-shaped structure, and its bottom is fixed to the support assembly 100 by bolts. The second caliper 230 has a first notch at its bottom, which engages with the support assembly 100. The second caliper 230 slides back and forth on the support assembly 100 along a first direction 610. The jaws of the first caliper 220 and the second caliper 230 are positioned opposite each other, forming a clamping jaw 210 between them. Under the push of the drive assembly 400, the second caliper 230 moves closer to the first caliper 220, thereby clamping the insulation layer 510 of the non-cut area of ​​the wire 500. The cooperation of the first caliper 220 and the second caliper 230 can effectively fix the insulation layer 510 of the non-cut area of ​​the wire 500, so that the insulation layer 510 of the cut area of ​​the wire 500 can be effectively separated when it is peeled off.

[0038] The first caliper 220 and the second caliper 230 have several anti-slip grooves on their opposing surfaces to prevent the wire 500 from slipping when gripping the insulation layer 510 in the non-cutting area.

[0039] The clamping assembly 200 also includes a first limiting block 240 fixed to the support assembly 100. The first limiting block 240 has a limiting portion 241 that abuts against the second caliper 230. When the second caliper 230 moves along the sliding path, the limiting portion 241 cooperates with the limiting stop portion 231 of the second caliper 230 to constrain the maximum sliding stroke of the second caliper 230. The first limiting block 240 is a plate structure fixed to the support assembly 100. The limiting portion 241 is located at the end of the first limiting block 240 facing the second caliper 230. The limiting portion 241 includes a second sliding groove and a limiting end. The second sliding groove engages with a limiting piece fixedly provided on the second caliper 230, thereby restricting the movement of the second caliper 230 in the second direction 620. The limiting end is located on the sliding path of the second caliper 230 and cooperates with the limiting stop portion 231 of the second caliper 230 to constrain the maximum sliding stroke of the second caliper 230. The first limiting block 240 can limit the sliding path and sliding stroke of the second caliper 230, ensuring that the second caliper 230 always reciprocates along the first direction 610, thereby limiting the size between the jaws 210 of the first caliper 220 and the second caliper 230.

[0040] Wire stripping assembly 300:

[0041] like Figures 2-3 As shown, the wire stripping assembly 300 includes a cutting tool system 310 and a cutting tool holder 320. The cutting tool system 310 is connected to the cutting tool holder 320, and the cutting tool holder 320 is adapted to move the cutting tool system 310 along a second direction 620 to strip the wire insulation layer 510. The cutting tool holder 320 is a plate-shaped structural component with a second notch. The second notch is engaged with the support assembly 100 and slides back and forth along the second direction 620 on the support assembly 100. The wire stripping assembly 300 includes a first return spring 330. One end of the first return spring 330 is connected to the cutting tool holder 320, and the other end is connected to the support assembly 100. The first return spring 330 is configured to drive the cutting tool holder 320 to move along the second direction 620 and then return to its original position.

[0042] The cutting tool system 310 includes a first cutting edge 311 and a second cutting edge 312, with the cutting tips of the first cutting edge 311 and the second cutting edge 312 positioned opposite each other to form a cutting edge 313. The first cutting edge 311 and the second cutting edge 312 are adapted to cut the wire insulation layer 510 located within the cutting edge 313. The first cutting edge 311 is fixed to a tool holder 320. The second cutting edge 312 is slidably connected within a first groove in the tool holder 320. The base of the second cutting edge 312 slides along the first groove to move closer to or further away from the first cutting edge 311.

[0043] Specifically, the first cutting edge 311 is fixed to the blade holder 320 by bolts. The bottom extension of the second cutting edge 312 is slidably connected in the first groove and slides back and forth along the first groove. The heads of the first cutting edge 311 and the second cutting edge 312 slide towards each other or away as the extension slides, and when they come together, they cut the insulating layer 510 in the cutting area located within the cutting edge 313. A second return spring 340 is fixedly connected to the second cutting edge 312, and the other end of the second return spring 340 is connected to the support assembly 100. When the second cutting edge 312 slides in the first groove, the second return spring 340 accumulates elastic potential energy to drive the second cutting edge 312 back to its initial position. After the force driving the second cutting edge 312 towards the first cutting edge 311 disappears, the second return spring 340 releases the accumulated elastic potential energy, causing the second cutting edge 312 to return to its initial position.

[0044] The wire stripping assembly 300 includes a second limiting block 350 fixed to the support assembly 100. The second limiting block 350 has a limiting plane 351 that abuts against the cutter holder 320, limiting the displacement of the cutter holder 320 in a first direction 610. The second limiting block 350 can abut against the side of the cutter holder 320, thereby limiting the displacement of the cutter holder 320 in the first direction 610, so that the cutter holder 320 can only move along the second direction 620.

[0045] like Figure 2 As shown, a wire stop block 360 is connected to the tool holder 320. The wire stop block 360, the cutting edge 313, and the clamping jaws 210 are arranged coaxially. The wire stop block 360 is located radially outward of the cutting edge 313. The wire 500 is inserted sequentially from the clamping jaws 210 and the cutting edge 313, with its end abutting against the wire stop block 360. The tool holder 320 has a first sliding post 361 extending along a second direction 620. The wire stop block 360 is slidably connected to the first sliding post 361 and is configured to slide along the axial direction of the first sliding post 361 to adjust the distance between it and the cutting edge 313. The wire stop block 360 has an adjusting knob 362, which is connected to the first sliding post 361. When the adjusting knob 362 is rotated clockwise, the threaded post at the bottom of the adjusting knob 362 moves toward the first sliding post 361 and abuts against it, thereby locking the position of the wire stop block 360 on the first sliding post 361. Conversely, rotating the knob counterclockwise will loosen the wire stop block 360 and adjust its position on the first slide bar 361.

[0046] Support component 100:

[0047] like Figures 2-4As shown, the support assembly 100 includes a main clamp frame 110. An elongated slot 113 is formed on the main clamp frame 110 along a first direction 610. A first mounting platform 111 and a second mounting platform 112 are respectively disposed on both sides of the elongated slot 113. A clamping assembly 200 is assembled on the first mounting platform 111, and a wire stripping assembly 300 is mounted on the second mounting platform 112. The first mounting platform 111, the second mounting platform 112, and the elongated slot 113 combine to form a U-shaped plate structure.

[0048] Specifically, the first clamp 220 of the clamping assembly 200 is bolted to the first mounting platform 111, and the first notch at the bottom of the second clamp 230 is slidably connected to the side of the first platform. The first notch... The second caliper 230, positioned at the side, engages with the first limiting plate to limit its movement in the second direction 620, preventing it from sliding. A second notch on the tool holder 320 of the drive assembly 400 slidably connects to the side of the second platform. The second limiting plate and the baffle at the end of the second mounting platform 112 limit the tool holder 320 on both sides in the first direction 610, ensuring that the tool holder 320 can only slide along the second direction 620.

[0049] like Figure 8 As shown, the support assembly 100 also includes an ergonomic grip housing 120, with its front end forming a tool mounting portion 121 and its rear end forming a grip portion 122. The main clamp 110 is fixed to the tool mounting portion 121, and the trigger switch 123 of the motor 410 is located in the transition area between the grip portion 122 and the tool mounting portion 121. Specifically, the housing 120 can be pistol-shaped, formed by joining two pistol-shaped half-housings 120. The grip portion 122 of the pistol-shaped housing 120 resembles a pistol handle, while its tool mounting portion 121 is located in a position similar to the muzzle of a pistol. The trigger of the pistol-shaped housing 120 serves as the activation switch.

[0050] Driver component 400:

[0051] like Figures 3-7As shown, the drive assembly 400 includes a motor 410 and a threaded drive mechanism 420. The threaded rod 421 of the threaded drive mechanism 420 is coaxially connected to the output shaft of the motor 410, and the threaded rod 421 is axially positioned within a long slot 113. Specifically, one end of the threaded rod 421 is connected to the output shaft of the motor 410 and rotates with the output shaft of the motor 410 within the long slot 113. The threaded drive mechanism 420 includes a moving block 422, which has a threaded hole that engages with the threaded rod 421. The moving block 422 extends to form a stop portion 4221, which slidably fits against the inner wall of the long slot 113 and forms an anti-rotation pair with the long slot 113. The moving block 422 is configured to reciprocate along the axial direction of the threaded rod 421. When the threaded rod 421 rotates, the threaded hole of the moving block 422 engages with the threaded rod 421. Because the inner wall surface of the long groove 113 of the stop portion 4221 of the moving block 422 forms an anti-rotation pair (preventing the moving block 422 from rotating with the threaded rod 421), the moving block 422 can only move along the axial direction of the threaded rod 421. By adjusting the rotation direction of the threaded rod 421, the moving block 422 can be driven to reciprocate along the threaded rod 421.

[0052] A drive block 430 is fixedly connected to the movable block 422. The drive block 430 includes a first wing plate 431 slidably connected to the first mounting platform 111 and a second wing plate 432 slidably connected to the second mounting platform 112. The drive block 430 has a through hole in the middle, which fits onto the threaded rod 421. The drive block 430 is fixed to the movable block 422 by bolts and moves synchronously with the movable block 422. The first wing plate 431 and the second wing plate 432 on both sides of the drive block 430 extend from the middle of the drive block 430 to both sides of the elongated groove 113 and overlap the first mounting platform 111 and the second mounting platform 112 respectively.

[0053] The first wing plate 431 has an installation channel 4311, within which a compression spring 433 is placed. One end of the compression spring 433 elastically abuts against the pressure-bearing end face of the telescopic rod 434. The other end of the telescopic rod 434 is fixedly connected to the second clamp 230. When the first wing plate 431 moves towards the clamping assembly 200 on the first mounting platform 111, it pushes the compression spring 433 and the telescopic rod 434 to move synchronously. Subsequently, it pushes the second clamp 230 closer to the first clamp 220, causing the clamping jaws 210 to narrow. When the clamping jaws 210 narrow to the outer diameter of the wire 500, the second clamp 230 clamps the wire insulation layer 510. At this time, the first wing plate 431 continues to move under the drive of the moving block 422, and the compression spring 433 is compressed and stores elastic potential energy. This structure ensures that the drive block 430 can continue to move forward even when the second clamp 230 is clamping the insulation layer 510 in the non-cutting area of ​​the wire 500.

[0054] The second cutting edge 312 of the cutting tool system 310 is positioned on the moving trajectory of the drive block 430. When the drive block 430 moves along the moving trajectory, it contacts and engages with the bearing surface of the second cutting edge 312. Responding to the mechanical action of the drive block 430, the second cutting edge 312 generates a closed displacement stroke towards the first cutting edge 311. The closed displacement strokes of the first cutting edge 311 and the second cutting edge 312 form a cutting path that covers the radial cutting area of ​​the wire insulation layer 510. The drive block 430 pushes the second cutting edge 312 closer to the first cutting edge 311, reducing the size of the cutting edge 313. The closed displacement stroke of the second cutting edge 312 forms a cutting path that only covers the thickness of the wire insulation layer 510, cutting through the insulation layer 510 without damaging the core wire 520 of the wire 500.

[0055] The second wing plate 432 moves synchronously with the drive block 430. The second wing plate 432 is connected to the wire stripping assembly 300 via an inclined slide mechanism 440. The inclined slide mechanism 440 includes a first wedge block 441 disposed at one end of the second wing plate 432, and the second wing plate 432 and the first wedge block 441 are integrally formed. The second wedge block 442 is disposed on the base in the wire stripping assembly 300, and the second wedge block 442 is integrally formed with the base. The second wedge block 442 is located at the opposite end of the first wedge block 441. The mating surfaces of the first wedge block 441 and the second wedge block 442 have an inclination angle αa, which is the angle between the mating surfaces and the first direction 610, 30°≤α≤60°, preferably 45°. When the moving block 422 drives the second wing plate 432, the inclined slide mechanism 440 converts the displacement of the first direction 610 into the displacement of the wire stripping assembly 300 cutter holder 320 in the second direction 620. Specifically, the second wedge block 442 is located on the moving path of the first wedge block 441. When the first wedge block 441 moves with the second wing plate 432 and contacts the second wedge block 442, the first wedge block 441 continues to move along the first direction 610. Due to the engagement angle α, the second wedge block 442 is pressed by the first wedge block 441 and moves along the second direction 620. When the tool holder 320, which is integrally connected to the second wedge block 442, moves along the second direction 620 with the second wedge block 442, it drives the tool system 310 connected to it to move along the second direction 620, thereby peeling the wire insulation layer 510 located in the cutting edge 313 from the wire 500.

[0056] like Figure 7 As shown, the drive assembly 400 also includes a power supply battery 130 and a circuit board 140, which are electrically connected to the motor 410. The battery body and the circuit board 140 are located inside the housing 120. The battery, circuit board 140, and motor 410 are electrically connected by wires 500. Example 2

[0057] like Figures 8-9As shown in this application, a method for cutting and peeling the insulation layer 510 of an electrical wire is provided, comprising the following steps: S10: Wire 500 Positioning and Clamping

[0058] S11. Insert the wire 500 into the clamping jaw 210 of the clamping assembly, and make the end of the wire 500 pass through the clamping jaw 210 and the blade 313 of the cutting tool system 310 in sequence, and finally abut against the wire stop block 360. S12. Start the motor 410. The threaded rod 421 of the drive assembly 400 rotates with the motor 410, causing the moving block 422 and the drive block 430 connected to the threaded rod 421 to move synchronously along the first direction 610. S13, the first wing plate 431 on the drive block 430 pushes the compression spring 433, the telescopic rod 434 and the second caliper 230 connected to the end of the telescopic rod 434 to move synchronously along the first direction 610, the clamping jaw 210 continuously shrinks, and finally clamps and fixes the non-cutting area insulation layer 510 of the wire 500. S20: Insulation layer 510 cutting execution

[0059] S21, the drive block 430 moves along the moving trajectory to contact the bearing surface of the second blade 312 disposed on the moving trajectory of the drive block 430, the second blade 312 moves toward the cutting path formed by the closed displacement stroke of the first blade 311, the blade 313 continues to shrink, cutting off the insulation layer 510 of the wire 500. S30: Wire insulation layer 510 stripping:

[0060] S31, the second wing plate 432 of the drive block 430 moves along the first direction 610, the first wedge block 441 connected to the second wing plate 432 contacts the second wedge block 442 connected to the cutter holder 320, and pushes the second wedge block 442 to move along the second direction 620, thereby causing the first blade 311 and the second blade 312 connected to the cutter holder 320 to clamp the cut wire insulation layer 510 and detach it from the wire core 520 of the wire 500; S40: Reset

[0061] S41, the motor 410 rotates in the opposite direction, the moving block 422 drives the drive block 430 to move in the opposite direction along the first direction 610, and the tool holder 320 is reset under the action of the second reset spring 340. S42, the second blade 312 is reset by the action of the first reset spring 330; S43, the second caliper 230 moves and resets synchronously in the opposite direction along with the telescopic rod 434 and the drive block 430.

[0062] The wire insulation cutting and stripping method of this application utilizes a drive component to drive a clamping component to hold the non-cutting insulation layer of the wire. Subsequently, the cutting tool system of the stripping component cuts the insulation layer, and the cut insulation layer is detached from the wire core by the power traction of the drive component. The entire process requires no manual operation of the cutting and stripping actions, achieving a fully automated process from positioning and clamping to cutting and stripping of the wire insulation. Compared with traditional manual wire strippers, this solution replaces manual labor with electric drive, not only reducing the operator's labor intensity and avoiding hand injuries caused by prolonged holding and force, but also ensuring consistent cutting depth and stripping length for each stripping operation through precise control of the drive component's operating parameters, thus improving the stability of stripping quality. It is particularly suitable for batch processing scenarios of wires with different diameters, meeting the demand for high-efficiency and high-precision stripping operations in large-scale cabling projects.
