[0015] The beneficial effects of the present application are as follows: The application provides a wire harness tail end automatic peeling and wire twisting processing machine, which is characterized in that a peeling assembly is arranged, when the peeling assembly is started, an electric push rod on the vertical plate pushes the clamping block to be close to the wire harness body, the skin breaking knives with equidistant circular distribution on the inner wall of the clamping block are in contact with the wire harness body, the triangular blades (the width gradually decreases in the direction close to the wire harness body) of the skin breaking knives preliminarily break the skin, the width decreasing design can avoid the blade surface directly contacting the internal copper wire of the wire harness, and reduce the risk of copper wire damage, and the end of the triangular blade is a regular hexagon, so that the blade edge is symmetrical and sharp, when the skin breaking knives contact the skin of the wire harness body, the skin can be cut from multiple angles at the same time, which can ensure the uniformity of the skin breaking, avoid the problems of skewed skin incision caused by single direction cutting and uneven stress of subsequent skin peeling, and can reduce the stress load of a single blade edge through the synergistic effect of multiple blade edges, prolong the service life of the triangular blade, the side blades on both sides of the triangular blade can further expand the skin incision, so that the skin of the expanded incision is more easily broken during subsequent twisting and peeling, the side blade on one side of the outer wall of the triangular blade is fixedly connected with the arc-shaped blade at one end, the arc-shaped blade can reduce the resistance of the skin of the wire harness body during skin breaking, so that the triangular blade and the side blade can more easily pierce the skin, improve the peeling smoothness, and the bevel gear blade (the width also decreases in the direction of the wire harness) at the end is the blade surface that first contacts the skin of the wire harness body, which can accurately pierce the skin and lay the foundation for subsequent skin breaking, and can avoid extruding or scraping the internal copper wire due to the large blade surface, further guarantee the integrity of the copper wire, the skin breaking design of multiple blades and width decreasing can effectively solve the problem of traditional cutting knives completely cutting the skin and easily damaging the copper wire, improve the skin peeling efficiency, and maximize the guarantee of the wire harness quality, and provide a good foundation for the subsequent wire twisting process.

[0016] This invention provides an automatic wire harness end stripping and twisting machine. Through a second clamping assembly, when the motor in the rotary displacement assembly is started, the motor output drives the rotating frame to rotate. The first threaded screw at one end of the rotating frame engages with the first threaded sleeve, driving the cylindrical shell to move horizontally under the sliding guidance of the guide post and guide cylinder, ensuring stable displacement. Furthermore, the gear cylinder outside the rotating frame meshes with the gear ring frame, driving the rotating post inside the gear ring frame to rotate. The rotating post then drives the second clamping assembly to rotate synchronously. During the horizontal displacement of the cylindrical shell, its internal second gear ring first meshes with the first gear that rotates along with the clamping shell. At this time, the... The meshing of the first gear and the second gear ring drives the second shaft to rotate, which in turn drives the second helical gear to rotate. The second helical gear then drives the first helical gear meshing with it to rotate. The rotation of the first helical gear causes the second threaded screw inside the clamping housing to rotate. The second threaded screw cooperates with the second threaded sleeve to push the second slider to slide in the third through groove of the clamping housing. This causes the mounting base and the second fixing plate to move the clamping plate closer to the wire harness body, thus clamping and fixing the wire harness body. The arc-shaped groove on the clamping plate increases the contact area with the wire harness, further improving the clamping effect of the clamping plate.

[0017] This invention provides an automatic wire harness end stripping and twisting machine. Through a rotating displacement component, after the clamping plate clamps and fixes the wire harness body, as the second clamping component moves horizontally along with the cylindrical shell, the fixed second gear ring separates from the first gear. This ensures that the second clamping component maintains a clamping state throughout the subsequent stripping and twisting process. The second clamping component continuously rotates and twists the wire harness body while clamping it. During this process, the copper wires inside the wire harness body can twist inside the outer sheath, preventing the copper wires from becoming scattered or misaligned, ensuring the regularity and tightness of the twisted wires, and improving the twisting quality. Simultaneously, due to the second clamping... The clamping component maintains a stable clamping state throughout, and the twisting and stripping processes are carried out simultaneously. Under the action of the stripping component, the outer sheath has formed a cut that facilitates separation. When the copper wire is twisted inside the outer sheath, it will not be excessively pulled or obstructed by the outer sheath. This ensures the smoothness of the twisting action and reduces damage to the copper wire caused by external pulling. At the same time, the continuous action of the stripping component ensures thorough stripping. The entire process achieves simultaneous stripping and twisting. Compared with the traditional method of stripping and then twisting, it greatly improves work efficiency. Furthermore, the precise cooperation of each component and the protective shell further ensure the safety and stability of the processing, ultimately efficiently completing the stripping and twisting of the wire harness end.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0035] Please see Figures 1-14 An automatic stripping and twisting machine for wire harness tail ends includes a base 1. A protective shell 2 and a fixed seat 3 are fixedly connected to the top outer wall of the base 1. A wire tube 4 for ensuring stable feeding of the wire harness body 5 is fixedly connected to one side of the fixed seat 3. A first clamping component 6 and a second clamping component 9 are respectively provided on the top of the base 1 and inside the protective shell 2 to ensure that the wire harness body 5 remains stable during stripping and twisting. The protective shell 2 is equipped with a stripping component 8 for accelerating the stripping of the wire harness body 5 and a rotational displacement component 7 for twisting the wire harness body 5. The second clamping assembly 9 is driven by the horizontal displacement and rotational motion of the rotary displacement assembly 7 to clamp and fix the wire harness body 5. A mounting post 11 is provided on one side of the second clamping component 9. A trigger switch 12 is fixedly connected to one end of the mounting post 11. When one end of the wire harness body 5 touches the trigger switch 12, the first clamping component 6, the rotation displacement component 7, the stripping component 8, and the second clamping component 9 are activated. The entire process realizes the simultaneous stripping and twisting of the wire. Compared with the traditional method of stripping and then twisting the wire, the work efficiency is greatly improved. Moreover, the precise cooperation of each component and the protective function of the protective shell 2 further ensure the safety and stability of the processing process, and finally efficiently complete the stripping and twisting of the wire harness tail end.

[0036] Furthermore, the first clamping assembly 6 includes an electric cylinder 601 fixedly connected to the inner wall of the bottom of the base 1. A lifting plate 602 is fixedly connected to the output end of the electric cylinder 601 extending to the top of the protective shell 2. First fixing posts 609 are fixedly connected to the outer walls of both sides of the lifting plate 602. A connecting rod 606 is provided on one side of the first fixing post 609. The connecting rod 606 has a V-shaped cross-section, and a first movable groove 610 and a second movable groove 614 are respectively opened on one side of the connecting rod 606. The first fixing post 609 slides inside the first movable groove 610. A first fixing plate 605 is fixedly connected to the top outer wall of the protective shell 2. A first rotating shaft 611 is fixedly connected to both sides of the first fixing plate 605. One end of the first rotating shaft 611 is rotatably connected to a connecting rod 606. A sliding groove 612 is formed on the top outer wall of the first fixing plate 605. A first slider 608 is slidably connected inside the sliding groove 612. A connecting block 607 is fixedly connected to the top outer wall of the first slider 608. A clamping seat 603 for clamping and fixing the wire harness body 5 is fixedly connected to the top outer wall of the connecting block 607. Both outer walls of the first clamping assembly are fixedly connected with second fixing posts 613, which slide inside the second movable groove 614. Two clamping seats 603 are staggered, and each clamping seat 603 has a mating groove 604 on one side. The clamping seats 603 are interlocked through the mating groove 604. When the first clamping assembly 6 is working, the electric cylinder 601 drives the lifting plate 602 to rise rapidly. During the rise of the lifting plate 602, the first fixing posts 609 on both sides of the lifting plate 602 slide in the first movable groove 610 of the connecting rod 606. The movement drives the V-shaped connecting rod 606 to rotate around the first rotating shaft 611 on the first fixed plate 605. When the connecting rod 606 rotates, it cooperates with the second fixed posts 613 on both sides of the connecting block 607 through the second movable groove 614, pushing the first slider 608 to slide in the sliding groove 612, so that the two staggered clamping seats 603 can be inserted into each other through the mating groove 604, realizing the stable clamping of the wire harness body 5. This clamping method, through the transmission of the connecting rod 606 and the insertion cooperation, ensures the clamping stability and avoids the wire harness shifting during the clamping process, which would affect subsequent processing.

[0037] Furthermore, the peeling assembly 8 includes a vertical plate 801 fixedly connected to the top outer wall of the base 1. An electric push rod 802 is fixedly connected to one side outer wall of the vertical plate 801. A clamping block 803 is fixedly connected to the output end of the electric push rod 802. A peeling blade 804 distributed in a circular pattern at equal intervals is fixedly connected to the inner circumference of the clamping block 803. When the peeling assembly 8 is activated, the electric push rod 802 on the vertical plate 801 pushes the clamping block 803 closer to the wire harness body 5. The peeling blades 804 distributed in a circular pattern at equal intervals on the inner wall of the clamping block 803 contact the wire harness body 5 and puncture its surface outer sheath.

[0038] Furthermore, the skin-piercing knife 804 includes a triangular blade 80401, a side blade 80402, an arc-shaped blade 80403, and a conical blade 80404. The width of the triangular blade 80401 gradually decreases along the direction close to the wire harness body 5, and the end of the triangular blade 80401 is hexagonal. The side blades 80402 are located on both sides of the triangular blade 80401, with three side blades 80402 on one side of the triangular blade 80401. One end of the side blade 80402 located in the middle of the outer wall of one side of the triangular blade 80401 is fixedly connected to the arc-shaped blade 80403. The conical blade 80404 is fixedly connected to the arc-shaped blade 80403. The triangular blade 80401, which is fixedly connected to the end of the triangular blade 80404 (its width gradually decreases along the direction close to the wire harness body 5), first performs initial cutting. Its decreasing width design avoids excessively large blade surfaces directly contacting the internal copper wires of the wire harness, reducing the risk of copper wire damage. Furthermore, the end of the triangular blade 80401 is hexagonal, thus possessing multiple sets of symmetrical and sharp cutting edges. When in contact with the surface of the wire harness body 5, it can simultaneously cut into the surface from multiple angles, ensuring uniform cutting and avoiding the problems of skewed cuts and uneven force during subsequent peeling caused by cutting in one direction. Furthermore, the synergistic effect of multiple blades reduces the stress load on a single blade, extending the service life of the triangular blade 80401. The side blades 80402 on both sides of the triangular blade 80401 further enlarge the epidermal incision, making it easier to break through the enlarged incision during subsequent twisting and peeling. One end of the side blade 80402, located in the middle of the outer wall of one side of the triangular blade 80401, is fixedly connected to the arc-shaped blade 80403. The arc-shaped blade 80403 reduces the resistance of the wire harness body 5 epidermis during peeling, allowing the triangular blade 80401 and side blades 80402 to more easily pierce the epidermis, improving the peeling process. The tapered blade 80404 at the end (with its width decreasing towards the wire harness) is the first blade to contact the outer sheath of the wire harness body 5. With its sharp tooth structure and decreasing width, it can accurately penetrate the outer sheath, laying the foundation for subsequent sheath-breaking operations. It can also avoid squeezing or scraping the internal copper wires due to excessive blade size, further ensuring the integrity of the copper wires. This multi-blade collaborative sheath-breaking design with decreasing width effectively solves the problem that traditional cutters may accidentally damage the copper wires when completely cutting off the outer sheath. While improving the sheath-breaking efficiency, it maximizes the quality of the wire harness and provides a good foundation for the subsequent wire twisting process.

[0039] Furthermore, the outer circumferential wall of the cylindrical shell 10 is provided with a first through groove 709 and a second through groove 710, respectively. The first connecting rod 915 and the second connecting rod 916 pass through the interior of the first through groove 709 and the second through groove 710, respectively. The first toothed ring 913 and the second toothed ring 914 are both located inside the cylindrical shell 10. The second clamping assembly 9 includes a clamping shell 905 fixedly connected to one end of the rotating column 705. A second threaded screw 919 is rotatably connected to one side of the inner wall of the clamping shell 905. A first helical gear 912 is fixedly connected to one end of the second threaded screw 919 extending to the outside of the clamping shell 905. A second helical gear 917 meshes with the outer circumferential wall of the first helical gear 912. A rotating seat 911 is fixedly connected to one side of the outer wall of the clamping shell 905. A second rotating shaft 918 is fixedly connected to the inner circumference of wheel 917. The second rotating shaft 918 is rotatably connected to rotating seat 911. A first gear 909 is fixedly connected to the outer circumference of the second rotating shaft 918. A second gear 910 meshes with the outer circumference of the first gear 909. The thickness of the first gear 909 is greater than the thickness of the second gear 910. The second gear 910 meshes with a first gear ring 913. The first gear 909 meshes with a second gear ring 914. A second threaded sleeve 908 meshes with the outer circumference of the second threaded screw 919. A second slider 907 is fixedly connected to both outer walls of the second threaded sleeve 908. A third through groove 906 is provided on both the upper and lower sides of the clamping shell 905. The second slider 907 is slidably connected to the third through groove 906. A mounting base 920 is fixedly connected to one side of the outer wall of the slider 907. A second fixing plate 904 is fixedly connected to one side of each mounting base 920. Equally spaced reinforcing columns 903 are fixedly connected to one side of the outer wall of the second fixing plate 904. A clamping plate 901 for clamping and fixing the wire harness body 5 is fixedly connected to the other end of the reinforcing column 903. Equally spaced arc-shaped grooves 902 are provided on one side of the outer wall of the clamping plate 901. When the motor 701 in the rotary displacement assembly 7 is started, the output end of the motor 701 drives the rotating frame to rotate. A first threaded screw 707 at one end of the rotating frame cooperates with a first threaded sleeve 702, driving the cylindrical shell 10 to move horizontally under the sliding guidance of the guide column 706 and the guide cylinder 711, ensuring stable displacement. The gear cylinder 703 of the part meshes with the gear ring frame 704, driving the rotating column 705 inside the gear ring frame 704 to rotate. The rotating column 705 then drives the second clamping assembly 9 to rotate synchronously. During the horizontal displacement of the cylindrical shell 10, the second gear ring 914 inside it will first mesh with the first gear 909 that rotates together with the clamping shell 905. At this time, under the action of the first gear 909 and the second gear ring 914 meshing with each other, the second rotating shaft 918 can be driven to rotate. The second rotating shaft 918 can drive the second helical gear 917 to rotate together. At this time, the second helical gear 917 can drive the first helical gear 912 that meshes with it to rotate. The rotation of the first helical gear 912 can cause the second threaded screw 919 inside the clamping shell 905 to rotate.The second threaded screw 919 cooperates with the second threaded sleeve 908 to push the second slider 907 to slide within the third through groove 906 of the clamping housing 905. This causes the mounting base 920 and the second fixing plate 904 to move the clamping plate 901 closer to the wire harness body 5, achieving clamping and fixing of the wire harness body 5. The arc-shaped groove 902 on the clamping plate 901 increases the contact area with the wire harness, further improving the clamping effect of the clamping plate 901.

[0040] Furthermore, the rotary displacement assembly 7 includes a rotary displacement component 7 fixedly connected to one side of the outer wall of the protective shell 2, a motor 701 on one side of the outer wall of the rotary displacement assembly 7, a rotating frame fixedly connected to the output end of the motor 701, a first threaded screw 707 fixedly connected to one end of the rotating frame, a first threaded sleeve 702 threadedly connected to the outer circumference of the first threaded screw 707, a cylindrical shell 10 fixedly connected to the bottom of the first threaded sleeve 702, guide posts 706 fixedly connected to both sides of the inner wall of the protective shell 2, guide cylinders 711 slidably connected to the outer circumference of the guide posts 706, guide cylinders 711 fixedly connected to the cylindrical shell 10, a gear cylinder 703 fixedly connected to the outside of the rotating frame, a gear ring frame 704 meshing with the outer circumference of the gear cylinder 703, a rotary column 705 fixedly connected to the inner circumference of the gear ring frame 704, and a second clamping assembly 9 fixedly connected to one end of the rotary column 705. The cylindrical shell 10 is fixedly connected to a first connecting rod 915 and a third through groove 906. The other ends of the first connecting rod 915 and the second connecting rod 916 are fixedly connected to a first toothed ring 913 and a second toothed ring 914, respectively. The inner diameter of the first toothed ring 913 is larger than that of the second toothed ring 914. When the clamping plate 901 clamps and fixes the wire harness body 5, as the second clamping assembly 9 moves horizontally along with the cylindrical shell 10, the fixed second toothed ring 914 will separate from the first gear 909, so that the second clamping assembly 9 will always maintain the clamping state during the subsequent peeling and twisting process. Then, the second clamping assembly 9 will continue to rotate and twist the wire harness body 5 during the clamping process. At this time, the copper wire inside the wire harness body 5 can twist inside the outer sheath, thereby avoiding the copper wire from becoming scattered or misaligned during the twisting process, ensuring the regularity and tightness of the twisted copper wire, and improving the twisting quality. Meanwhile, since the second clamping component 9 always maintains a stable clamping state, and the twisting process and the stripping process are carried out simultaneously, the outer sheath has formed a cut that is easy to separate under the action of the stripping component 8. When the copper wire is twisted inside the outer sheath, it will not be excessively pulled or obstructed by the outer sheath. This ensures the smoothness of the twisting action and reduces the damage to the copper wire caused by external force. At the same time, the continuous action of the stripping component 8 can ensure thorough stripping. The whole process realizes the simultaneous stripping and twisting. Compared with the traditional method of stripping and then twisting, it greatly improves the work efficiency. Moreover, the precise cooperation of each component and the protective shell 2 further ensure the safety and stability of the processing process, and finally efficiently completes the stripping and twisting of the wire harness tail. After the wire harness body 5 has finished stripping, the stripped outer sheath is still held by the second clamping assembly 9. At this time, the rotary displacement assembly 7 continues to work until the second gear 910 meshes with the first toothed ring 913 fixed inside the protective shell 2. At this time, the second gear 910 continues to perform circular motion. Since the second gear 910 meshes with the first gear 909, the first gear 909 rotates in the opposite direction. The reverse rotation of the first gear 909 can drive the second threaded screw 919 to rotate in the opposite direction as well, thereby resetting the entire second clamping assembly 9 and releasing the clamp on the stripped outer sheath. This completes the automatic unloading of the stripped outer sheath and ensures the stable progress of the stripping and twisting of the next wire harness body 5.

[0041] In summary, with the help of the above-mentioned technical solution of the present invention, when in use, the operator passes the wire harness body 5 to be processed through the wire tube 4. The wire tube 4 can play a good guiding role for the wire harness body 5 inserted into the protective shell 2, so that the wire harness body 5 can stably contact the trigger switch 12. When the wire harness body 5 contacts the trigger switch 12, the first clamping component 6, the stripping component 8, the second clamping component 9 and the rotation displacement component 7 are activated in sequence. When the first clamping assembly 6 is working, the electric cylinder 601 drives the lifting plate 602 to rise rapidly. During the rising process of the lifting plate 602, the first fixed posts 609 on both sides of the lifting plate 602 slide in the first movable groove 610 of the connecting rod 606, which drives the V-shaped connecting rod 606 to rotate around the first rotating shaft 611 on the first fixed plate 605. When the connecting rod 606 rotates, it cooperates with the second fixed posts 613 on both sides of the connecting block 607 through the second movable groove 614, pushing the first slider 608 to slide in the sliding groove 612, so that the two staggered clamping seats 603 can be inserted into each other through the mating groove 604 to achieve a stable clamping of the wire harness body 5. This clamping method ensures clamping stability through the transmission and insertion of the connecting rod 606 and avoids the wire harness shifting during the clamping process from affecting subsequent processing. Subsequently, the stripping assembly 8 is activated. The electric push rod 802 on the vertical plate 801 pushes the clamping block 803 closer to the wire harness body 5. The stripping blades 804, which are equidistantly distributed in circles on the inner wall of the clamping block 803, come into contact with the wire harness body 5. The triangular blades 80401 of the stripping blades 804 (the width gradually decreases along the direction close to the wire harness body 5) first perform initial stripping. The design of the decreasing width can avoid the blade surface being too large and directly contacting the copper wires inside the wire harness, reducing the risk of damage to the copper wires. In addition, the end of the triangular blade 80401 is hexagonal, so it has multiple sets of symmetrical and sharp cutting edges. When it comes into contact with the surface of the wire harness body 5, it can cut into the surface of the surface from multiple angles simultaneously. This not only ensures the uniformity of stripping and avoids the problem of uneven surface cut and uneven force in subsequent stripping caused by cutting in one direction, but also reduces the stress load on a single cutting edge through the synergistic effect of multiple cutting edges, extending the service life of the triangular blade 80401. The side blades 80402 on both sides of the triangular blade 80401 can further enlarge the... The outer sheath is cut to make it easier to break through the enlarged cut during subsequent twisting and peeling. The side blade 80402, located in the middle of the outer wall of the triangular blade 80401, is fixedly connected to the arc blade 80403. The arc blade 80403 reduces the resistance of the wire harness body 5 when breaking the sheath, allowing the triangular blade 80401 and the side blade 80402 to pierce the sheath more easily, improving the smoothness of peeling. At the same time, the tapered blade 80404 at the end (the width also decreases towards the wire harness) is the first blade to contact the sheath of the wire harness body 5. With its sharp tooth structure and decreasing width, it can accurately pierce the sheath, laying the foundation for subsequent peeling actions, and avoid squeezing or scraping the internal copper wires due to the excessive blade surface, further ensuring the integrity of the copper wires. This multi-blade collaborative peeling design with decreasing width effectively solves the problem that traditional cutters may accidentally damage the copper wires when completely cutting the sheath. While improving peeling efficiency, it maximizes the quality of the wire harness and provides a good foundation for the subsequent twisting process. Simultaneously, the motor 701 in the rotary displacement assembly 7 starts, and the output end of the motor 701 drives the rotating frame to rotate. The first threaded screw 707 at one end of the rotating frame cooperates with the first threaded sleeve 702, driving the cylindrical shell 10 to move horizontally under the sliding guidance of the guide post 706 and the guide cylinder 711, ensuring the stability of the displacement. At the same time, the gear cylinder 703 outside the rotating frame meshes with the gear ring frame 704, driving the rotating post 705 inside the gear ring frame 704 to rotate. The rotating post 705 then drives the second clamping assembly 9 to rotate synchronously. During the horizontal displacement of the cylindrical shell 10, the second gear ring 914 inside it will first mesh with the first gear 909 that rotates together with the clamping shell 905. At this time, under the action of the mutual meshing of the first gear 909 and the second gear ring 914, The second rotating shaft 918 can be driven to rotate, and the second helical gear 917 can be driven to rotate together. At this time, the second helical gear 917 can drive the first helical gear 912 meshing with it to rotate. The rotation of the first helical gear 912 can cause the second threaded screw 919 inside the clamping shell 905 to rotate. The second threaded screw 919 cooperates with the second threaded sleeve 908 to push the second slider 907 to slide in the third through groove 906 of the clamping shell 905. This causes the mounting base 920 and the second fixing plate 904 to drive the clamping plate 901 to move closer to the wire harness body 5 to achieve clamping and fixing of the wire harness body 5. The arc groove 902 on the clamping plate 901 can increase the contact area with the wire harness and further improve the clamping effect of the clamping plate 901. After the clamping plate 901 clamps and fixes the wire harness body 5, as the second clamping component 9 moves horizontally along with the cylindrical shell 10, the fixed second toothed ring 914 will separate from the first gear 909, so that the second clamping component 9 will always maintain the clamping state during the subsequent stripping and twisting process. Then, the second clamping component 9 will continue to rotate and twist the wire harness body 5 during the clamping process. At this time, the copper wire inside the wire harness body 5 can twist inside the outer sheath, thereby avoiding the copper wire from becoming scattered or misaligned during the twisting process, ensuring the regularity and tightness of the twisted copper wire, and improving the twisting quality. Meanwhile, since the second clamping component 9 always maintains a stable clamping state, and the twisting process and the stripping process are carried out simultaneously, the outer sheath has formed a cut that is easy to separate under the action of the stripping component 8. When the copper wire is twisted inside the outer sheath, it will not be excessively pulled or obstructed by the outer sheath. This ensures the smoothness of the twisting action and reduces the damage to the copper wire caused by external force. At the same time, the continuous action of the stripping component 8 can ensure thorough stripping. The whole process realizes the simultaneous stripping and twisting. Compared with the traditional method of stripping and then twisting, it greatly improves the work efficiency. Moreover, the precise cooperation of each component and the protective shell 2 further ensure the safety and stability of the processing process, and finally efficiently completes the stripping and twisting of the wire harness tail. After the wire harness body 5 has finished stripping, the stripped outer sheath is still held by the second clamping assembly 9. At this time, the rotary displacement assembly 7 continues to work until the second gear 910 meshes with the first toothed ring 913 fixed inside the protective shell 2. At this time, the second gear 910 continues to perform circular motion. Since the second gear 910 meshes with the first gear 909, the first gear 909 rotates in the opposite direction. The reverse rotation of the first gear 909 can drive the second threaded screw 919 to rotate in the opposite direction as well, thereby resetting the entire second clamping assembly 9 and releasing the clamp on the stripped outer sheath. This completes the automatic unloading of the stripped outer sheath and ensures the stable progress of the stripping and twisting of the next wire harness body 5.
