Description

Technical Field

[0001] This invention relates to the field of cable manufacturing technology, and more specifically, to a cable braiding device. Background Technology

[0002] In many industrial and maritime applications today, the ropes used are meticulously crafted from advanced synthetic fibers as the primary raw material. These synthetic fibers undergo rigorous selection and processing, resulting in excellent physical properties. Specifically, they are woven from multiple strands of sub-ropes using a specific process. These sub-ropes can be tightly wound together in the same twist direction or interwoven in a double twist structure. This scientifically sound weaving method gives the final rope numerous significant advantages. It possesses extremely high strength, capable of withstanding enormous tensile forces without easily breaking; simultaneously, it is very lightweight, facilitating handling and use; and it exhibits excellent wear resistance, maintaining its good condition even under prolonged and frequent use.

[0003] For this reason, this high-performance cable has been widely used in many important fields. For example, in ship equipment, it is one of the key components to ensure the safe navigation and stable berthing of ships; in port loading and unloading operations, it relies on its reliable performance to efficiently complete the lifting and transfer of cargo; and even in fields with extremely high equipment requirements, such as national defense and military industries, it plays an indispensable role.

[0004] In practical applications, to better meet diverse connection needs, depending on the specific usage scenario and requirements, sometimes the two ends or only one end of the cable are specially braided to form a regular loop structure. This design greatly facilitates the secure connection of the cable to various other objects, improving ease of use and flexibility. However, in the current industry situation, this crucial braiding work is mainly done manually by workers. In this traditional operating mode, workers need to repeat the same actions for extended periods, resulting in extremely high work intensity, easily leading to physical fatigue and injury, and relatively low work efficiency, making it difficult to meet the needs of large-scale production. More importantly, due to the inherent subjectivity and uncertainty of manual operation, the appearance and performance quality of the product are often inconsistent; products made by different workers may vary, posing a challenge to overall product quality control. Summary of the Invention

[0005] The purpose of this invention is to provide an automated device that can replace manual labor in cable splicing operations, thereby reducing the labor intensity of workers and improving product quality.

The horizontal and vertical connecting plates pass through the cylinder and are connected to the sliders of the vertical rail at both ends.

The upper shuttle clamping rod assembly and the lower shuttle clamping rod assembly are respectively arranged on the side of the two horizontal and vertical connecting plates that are close to each other, and the two ends of the upper shuttle clamping rod assembly and the lower shuttle clamping rod assembly are connected to the sliders of the horizontal rail. Two second linear drive components are fixed inside the cylinder and connected to the two horizontal and vertical connecting plates respectively, for driving the two horizontal and vertical connecting plates to move along the vertical rail respectively; The third linear drive mechanism is fixed inside the cylinder and is used to drive the upper shuttle clamping rod assembly and the lower shuttle clamping rod assembly to move synchronously and in the same direction along the horizontal rail.

[0012] Furthermore, both the upper shuttle clamping rod assembly and the lower shuttle clamping rod assembly include a clamping rod, a second clamping claw, and a telescopic claw; The clamping rod passes through the cylinder and extends out of the cylinder at one end near the strand control mechanism.

[0016] Compared with the prior art, the beneficial effects of the present invention are: Before using the cable braiding device of this invention, the strands of the cable are spread out at one end according to the required braiding length. A collar is bent according to the product collar size requirements, and the ends of the spread strands are fixed to the cable. One end of the cable collar is fixedly clamped to a first end clamping mechanism on one side, the cable is straightened, and the other end of the cable is fixed to a second end clamping mechanism. The strand control mechanism clamps the ends of each spread strand through multiple strand clamping and positioning components. The braiding mechanism clamps the ends of each strand in sequence for braiding, thereby realizing the braiding of the cable by the cable braiding device, saving labor and improving efficiency. Furthermore, during the braiding process, the tension on each strand is consistent, making the braided structure tight and ensuring the overall strength of the cable after braiding.

[0017] The cable braiding device of this invention clamps and fixes both ends of the cable through a first end clamping mechanism and a second end clamping mechanism, respectively, maintaining the cable in a stable state of near-rigidity during the braiding process. The strand control mechanism arranges the strands of the cable radially within a certain radial section of the cable, away from the braiding node and close to the braiding mechanism, and applies a certain tension to each strand to keep them taut; simultaneously, it ensures that the force on each strand is consistent during the braiding process. The braiding mechanism adopts a rotary symmetrical bidirectional braiding structure to complete the braiding of S and Z double-twist cables. Attached Figure Description

[0039] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0040] like Figure 8 As shown, the cable braiding device in this embodiment includes a first end clamping mechanism 1, a strand control mechanism 2, a braiding mechanism 3, a second end clamping mechanism 4, and a frame 5. The first end clamping mechanism 1, the strand control mechanism 2, the braiding mechanism 3, and the second end clamping mechanism 4 are sequentially and coaxially mounted on the frame 5.

[0041] The first end clamping mechanism 1 and the second end clamping mechanism 4 are used to clamp the cable and achieve clamping and positioning of the cable.

[0042] The strand control mechanism 2 includes a bracket 21 and multiple strand clamping and positioning components 22. The multiple strand clamping and positioning components 22 are arranged in a circular array within the bracket 21 for clamping and positioning each strand of the cable.

[0043] like Figure 13 and Figure 14 As shown, the insertion and braiding mechanism 3 includes a frame 31, a rotating assembly 32, a horizontal drive assembly 33, a rotating drive assembly 34, and an insertion and braiding assembly 35. The frame 31 is mounted on the machine frame 5, the rotating assembly 32 is mounted on the frame 31, the horizontal drive assembly 33 drives the frame 31 to move along the axis of the machine frame 5, the rotating drive assembly 34 drives the rotating assembly 32 to rotate, and the insertion and braiding assembly 35 is mounted inside the rotating assembly 32 and is sequentially connected to each strand to drive the strands to be inserted and braided.

[0044] In this invention, such as Figure 9 As shown, both the first end clamping mechanism 1 and the second end clamping mechanism 4 include a base 11, a third support plate 12, clamping claws 13, a fourth linear drive component 14, and a side guide rod 15. The base 11 is fixed to the frame 5. Two third support plates 12 are symmetrically and vertically fixed to the base 11, and the third support plates 12 are parallel to the length direction of the frame 5. Two clamping claws 13 are arranged opposite each other between the two third support plates 12. The fourth linear drive component 14 is mounted on the third support plate 12, and the fourth linear drive component 14 can drive the clamping claws 13 to move in a direction closer to and away from the third support plate 12. The two clamping claws 13 move closer to each other to clamp and fix the cable. Specifically, the fourth linear drive component 14 is an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder.

[0045] The side guide rod 15 is used to guide the movement of the clamping jaw 13. Specifically, the side guide rod 15 has an L-shaped structure. The two sides of the bent portion of the side guide rod 15 are parallel or perpendicular to the third support plate 12. The portion of the side guide rod 15 perpendicular to the third support plate 12 passes through the third support plate 12 and is slidably connected to the third support plate 12. The end of the side guide rod 15 parallel to the third support plate 12 and away from the third support plate 12 is fixedly connected to the clamping jaw 13. When the fourth linear drive member 14 drives the clamping jaw 13 to move, the portion of the side guide rod 15 perpendicular to the third support plate 12 slides against the third support plate 12, thereby effectively preventing the clamping jaw 13 from shifting during movement.

[0046] In this invention, such as Figure 10 As shown, the support 21 of the strand control mechanism 2 includes a first base plate 211, a first support plate 212, and a third mounting plate 213. The first base plate 211 is mounted on the frame 5, and the first support plate 212 is vertically fixed to the first base plate 211. The first support plate 212 has a first circular through hole, the axis of which is at the same height as the clamping claw 13. Multiple third mounting plates 213 are evenly distributed in a ring array within the first circular through hole of the first support plate 212, and each third mounting plate 213 corresponds to a strand clamping and positioning component 22. Preferably, a stiffening plate 214 is also provided between the outer side of the third mounting plate 213 and the first support plate 212. The stiffening plate 214 is perpendicular to the third mounting plate 213 and the first support plate 212, and the adjacent two side edges of the stiffening plate 214 are fixedly connected to the third mounting plate 213 and the first support plate 212, respectively.

[0047] like Figure 11 As shown, the strand clamping and positioning assembly 22 of the strand control mechanism 2 includes a first mounting plate 221, a second mounting plate 222, a first linear guide 223, a first gripper 224, and a first linear drive 225. The first mounting plate 221 is mounted on the side of the third mounting plate 213 opposite to the first support plate 212, and the first mounting plate 221 is parallel to the third mounting plate 213. The second mounting plate 222 is vertically fixed to the side of the first mounting plate 221 opposite to the bracket 21. The first linear guide 223 is fixed to the side of the second mounting plate 222 near the insertion and braiding mechanism 3, and the length direction of the first linear guide 223 is consistent with the length direction of the frame 5. The first gripper 224 is fixed to the slider of the first linear guide 223, and a proximity detection switch 227 is also provided on the slider of the first linear guide 223. The first linear drive 225 is connected to the second mounting plate 222 and drives the first gripper 224 to move along the first linear guide 223. Specifically, the first linear drive mechanism is an electric cylinder, hydraulic cylinder, or pneumatic cylinder, and the first linear drive mechanism has a built-in magnetic detection switch, and the first gripper 224 is a pneumatic gripper.

[0048] The extension and retraction of the first linear drive mechanism can drive the first gripper 224 and the proximity detection switch 227 to move horizontally. The first linear drive mechanism has a built-in magnetic detection switch that can stop at the extension and retraction points and at the end of the cable insertion.

[0049] Preferably, in this embodiment, the number of strand clamping and positioning components 22 is even, and the number of strand clamping and positioning components 22 is at least twice the number of strands. The strand clamping and positioning components 22 also include rope shuttles 226, which are arranged one-to-one with the strands and are tied to the ends of the unfurled strands. In use, as... Figure 12 As shown, the two strand clamping and positioning components 22 on the same radial line allow only one strand clamping and positioning component 22 to clamp and fix a rope shuttle 226, while the other is left unattended.

[0050] In this invention, such as Figure 15 As shown, the frame 31 of the insertion mechanism 3 includes a second base plate 311, a second support plate 312, and limiting wheels 313. The second base plate 311 is slidably mounted on the frame 5, and two second support plates 312 are vertically fixed on the second base plate 311 and are parallel to each other. The two second support plates 312 are coaxially provided with second circular through holes of the same radius, and the second circular through holes are coaxially arranged with the first circular through holes. A plurality of limiting wheels 313 are evenly distributed in a ring array on the opposite side of the two second support plates 312, and the limiting wheels 313 are located outside the second circular through holes. The limiting wheels 313 are rotatably connected to the second support plates 312.

[0051] like Figure 16 As shown, the rotating assembly 32 includes a cylindrical body 321 and limiting rings 322. The cylindrical body 321 is a horizontally arranged square cylindrical structure with holes at both ends. The cylindrical body 321 is inserted into the second circular through holes of the two second support plates 312, and the edges of the cylindrical body 321 and the second circular through holes are spaced apart. The two ends of the cylindrical body 321 are located on opposite sides of the two second circular through holes. The two limiting rings 322 are respectively fixed to the two ends of the cylindrical body 321, and the limiting rings 322 are located inside the multiple limiting wheels 313. The outer circumferential opening of the limiting rings 322 has an annular groove 323, which slides and engages with the limiting wheels 313. By the multiple limiting wheels 313 evenly installed on the second support plates 312 engaging the annular grooves 323 on both sides of the cylindrical body 321, the axial and radial limiting of the rotating assembly 32 is achieved, so that the rotating assembly 32 can only rotate around the axis.

[0052] The rotary drive assembly 34 includes a large gear 341, a small gear 342, and a rotary drive motor 343. The large gear 341 is fixed to one of the limiting wheels 313 on the side away from the cylinder 321. The small gear 342 is rotatably mounted on the corresponding second support plate 312 and meshes with the large gear 341. The rotary drive motor 343 is fixed to the inside of the second support plate 312 and is connected to the small gear 342 in a transmission manner. Specifically, the rotary drive motor 343 is a servo motor, which drives the gear set to achieve the rotary motion of the rotary assembly 32.

[0053] The horizontal drive assembly 33 includes a second linear guide 331, a ball screw 332, and a horizontal drive motor 333. The two second linear guides 331 are symmetrically fixed to both sides of the frame 5. The frame body 31 is positioned above the second linear guides 331, and the bottom surface of the second base plate 311 is fixedly connected to the slider of the second linear guide 331. The ball screw 332 is positioned below the second base plate 311, and the nut of the ball screw 332 is fixedly connected to the bottom surface of the second base plate 311. The horizontal drive motor 333 is mounted on one side of the ball screw 332 and is connected to it for transmission. Specifically, the horizontal drive motor 333 is a servo motor. The horizontal drive assembly 33, driven by the horizontal drive motor 333, moves the ball screw 332, causing the frame body 31 and its mounted components to move horizontally. The distance from the starting point to the insertion point is calculated based on the rotational pitch of the strands during cable weaving, and the assembly can stop at the starting point, the insertion end point, and the insertion point itself.

[0054] like Figure 17 and Figure 18 As shown, the insertion assembly 35 includes a vertical rail 351, a horizontal and vertical connecting plate 352, a horizontal rail 353, an upper shuttle clamping rod assembly 354, a lower shuttle clamping rod assembly 355, a second linear drive member 356, and a third linear drive member 357.

[0055] Vertical rails 351 are fixed at both ends of the cylinder 321, and vertical rails 351 are fixed on both sides of each end of the cylinder 321. Two sliders are slidably mounted on each vertical rail 351. Two horizontal and vertical connecting plates 352 are perpendicular to the vertical rails 351 and parallel to each other. The horizontal and vertical connecting plates 352 pass through the cylinder 321 and are connected to the sliders of the vertical rails 351 at both ends. Horizontal rails 353 are fixed at both ends of the horizontal and vertical connecting plates 352 and are perpendicular to the vertical rails 351. Upper shuttle clamping rod assembly 354 and lower shuttle clamping rod assembly 355 are respectively located on the side of the two horizontal and vertical connecting plates 352 that are close to each other, and the two ends of the upper shuttle clamping rod assembly 354 and lower shuttle clamping rod assembly 355 are connected to the sliders of the horizontal rail 353.

[0056] Two second linear drive components 356 are fixed inside the cylinder 321 and connected to two horizontal and vertical connecting plates 352 respectively, for driving the two horizontal and vertical connecting plates 352 to move along the vertical rail 351 respectively. Specifically, the second linear drive component 356 is an electric cylinder, hydraulic cylinder or pneumatic cylinder. The two sets of horizontal and vertical connecting plates 352 are respectively connected to the upper and lower sliders of the vertical rail 351, and under the extension and retraction of the second linear drive component 356, they realize linear movement along the vertical rail 351. The second linear drive component 356 has a built-in magnetic detection switch, which can meet the requirements of stopping at three fixed positioning points: the starting point, the ending point and a certain intermediate point.

[0057] The third linear drive mechanism is fixed inside the cylinder 321 and is used to drive the upper shuttle clamping rod assembly 354 and the lower shuttle clamping rod assembly 355 to move synchronously and in the same direction along the horizontal rail 353. Specifically, one end of the third linear drive mechanism is connected to one side of the lower shuttle clamping rod assembly 355, and the other end is fixed inside the cylinder 321. A vertical guide rod 358 is provided on the side of the lower shuttle clamping rod assembly 355 near the upper shuttle clamping rod assembly 354. The vertical guide rod 358 is arranged parallel to the vertical rail 351, and one end of the vertical guide rod 358 is fixed to the lower shuttle clamping rod assembly 355, while the other end is slidably connected to the upper shuttle clamping rod assembly 354. The third linear drive mechanism is an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder. The vertical guide rod 358 ensures that the various parts of the upper and lower shuttle clamping rod assemblies 355 correspond in the vertical direction. At the same time, when the third linear drive mechanism, which has the function of fine-tuning the position, is in action, the upper and lower shuttle clamping rod assemblies 355 move horizontally synchronously. An adjustable stroke detection switch is installed at the end position of the third linear drive mechanism to detect the horizontal movement distance of the upper and lower shuttle clamping rod assemblies 355.

[0058] In this invention, such as Figure 19 and Figure 20As shown, both the upper shuttle clamping rod assembly 354 and the lower shuttle clamping rod assembly 355 include a clamping rod body 3541, a second clamping jaw 3542, and a telescopic jaw 3543. The clamping rod body 3541 passes through the openings at both ends of the cylinder 321, and the end of the clamping rod body 3541 near the strand control mechanism 2 extends out of the cylinder 321. The clamping rod body 3541 is connected to the sliders of the horizontal rails 353 at both ends of the horizontal and vertical connecting plates 352. The second clamping jaw 3542 is installed at the end of the clamping rod body 3541 near the strand control mechanism 2, and the second clamping jaw 3542 is located on the side where the two clamping rod bodies 3541 are close to each other. A proximity switch sensing point 3544 is provided on the other side of the clamping rod body 3541. The telescopic claw 3543 is located on the side of the second claw 3542 near the cylinder 321 and is connected to the clamping rod body 3541. The telescopic claw 3543 is located on the side of the two clamping rod bodies 3541 that are close to each other. Specifically, the telescopic claw 3543 includes a telescopic rod, a spring, and a claw body. One end of the telescopic rod passes through the clamping rod body 3541 and is telescopically and slidably connected to the clamping rod body 3541, while the other end is fixedly connected to the claw body. The spring is sleeved on the outside of the telescopic rod and its two ends are fixedly connected to the claw body and the clamping rod body 3541, respectively. The second claw 3542 is a pneumatic claw.

[0059] The telescopic claw 3543 and the second claw 3542 are not coplanar. During insertion, the axis of the telescopic claw 3543 is perpendicular to the cable axis. It contacts the cable before the shuttle and compresses the spring. The telescopic claw 3543 moves in a direction close to the clamping rod body 3541. The axis of the shuttle held by the second claw 3542 is perpendicular to the position slightly smaller than the cable radius away from the cable axis and corresponds to the gap of the strand to be inserted.

[0060] Specifically, in this embodiment, the first linear drive 225, the second linear drive 356, the third linear drive 357 and the fourth linear drive 14 are all cylinders.

[0061] Taking a 12-strand cable as an example, a 12-strand braided rope includes 6 S-twists and 6 Z-twists, with S-twists (single or in pairs) and Z-twists (single or in pairs) alternating in braiding. The weave length is generally about 3.5 times the lay length. The loop length can be designed according to customer requirements. The traditional manual weave method is as follows: 1. For example Figure 1 As shown, divide the cable into 12 strands from the rope end along the weave path, with each strand being 3.5 times the twist length from the rope end, and mark this point with tape. Secure the end of each strand with tape along the twist direction of the rope strand.

[0062] 2. For example Figure 2As shown, divide the twelve strands into two equal groups (Group A and Group B). Group A and Group B are each further divided into three subgroups, arranged from left to right as S, Z, S and Z, S, Z respectively. Pass Group B through the middle of the rope root, according to... Figure 2 As shown, place the two sets of positions accordingly.

[0063] 3. Begin by selecting the single strand closest to the end of the loop and starting the weaving process. Interweave the strands of the weaving with the strands of the same twist direction, such as... Figure 3 and Figure 4 As shown. First, insert one flower into each strand, then arrange the inserted flowers to ensure even tension on each strand. For example... Figure 5 As shown.

[0064] 4. Plug-in: such as Figure 6 As shown, the beginning and end are connected by starting from any strand. The Z-twist (S-twist) strand is inserted into each strand of the rope root with the same twist direction from top to bottom, pressing down one strand and picking up another to connect.

[0065] 5. End treatment: such as Figure 7 As shown, use tape to tightly wrap the remaining ends of the rope after the weaving is completed.

[0066] The cable splicing device in this invention is mainly responsible for the work in steps 2-4 above.

[0067] Before splicing, spread out the strands of the cable at one end according to the required splicing length. Bend a loop according to the product loop size requirements and fix the ends of the spread strands to the cable. This fixing point is the splicing starting point. Specific fixing methods include wrapping with tape, binding the rope, etc. Fix one end of the cable loop to the first end clamping mechanism 1 on one side, straighten the cable, and fix the other end of the cable to the second end clamping mechanism 4 on the opposite side. The splicing starting point is located at the midpoint of the stroke of the first clamp 224.

[0068] The heads of each strand of rope are fixed to a rope shuttle, which is a cylindrical structure with tapered ends and four annular grooves symmetrically machined on both sides for clamping by the first gripper 224 and the second gripper 3542. The first gripper 224 clamps and fixes the outer annular groove on one side of the rope shuttle. When the rope shuttle is arranged on the rope control mechanism 2, only one of the two rope clamping and positioning components 22 on the same radial line is allowed to clamp and fix one rope shuttle, and the rope shuttles are arranged circumferentially according to the insertion and braiding sequence. Under the push of the first linear drive 225, the first gripper 224 moves away from the insertion and braiding starting point and the collar side. By adjusting the air intake pressure, the cylinder thrust meets the tension required by the rope during the insertion and braiding process until the cylinder stops pushing out, and the ropes are distributed in an inclined radial pattern around the cable.

[0069] The rotary drive assembly 34 drives the rotary assembly 32 to rotate, so that the second clamp 3542 in the upper shuttle clamping rod assembly 354 or the lower shuttle clamping rod assembly 355 is coplanar with the shuttle that fixes the first inserted strand rope in a plane passing through the cable axis. When the horizontal drive assembly 33 operates, it drives the frame 31 and its mounted components to move toward the strand control mechanism 2. When the proximity detection switch 227 in the strand clamping and positioning assembly 22 that clamps the first strand detects the sensing point corresponding to the upper and lower shuttle clamping rod assembly 355, it indicates that the first gripper 224 and the second gripper 3542 are vertically aligned. The second linear drive 356 pushes the horizontal and vertical connecting plates 352 to move toward the strand clamping and positioning assembly 22, so that the second gripper 3542 in the upper or lower shuttle clamping rod assembly 355 corresponds to the inner annular groove on one side of the shuttle, clamping the shuttle. At the same time, the first gripper 224 releases the shuttle. At this time, under the traction of the piston rod of the first linear drive 225, the first gripper 224 in all strand clamping and positioning assemblies 22 moves toward the other side of the insertion and weaving starting point, finally forming an inclined radial state that is symmetrical to the initial state, making room for insertion and weaving.

[0070] The piston rods of the two second linear drive members 356 retract to a preset point in the middle of their stroke. Driven by the horizontal drive assembly 33, the shuttle to be inserted moves to the insertion point of the cable. At the same time, the third linear drive member 357 extends, aligning the gap between the shuttle to be inserted and the strand to be inserted in the radial direction of the cable. The piston rods of the two second linear drive members 356 continue to retract, and the telescopic claw 3543 first contacts the cable and compresses the spring, finally clamping and positioning the cable near the insertion point to ensure that the cable is in a stable state during insertion. Simultaneously, the shuttle is inserted through the gap between the predetermined strands of the cable, and the two second jaws 3542 in the upper and lower shuttle clamping rod assemblies 355 approach each other, with their positions corresponding to the inner annular grooves on both sides of the shuttle. This means the piston rods of the two second linear drive members 356 retract completely, one side of the second jaw 3542 closes to clamp the shuttle, and the other side opens to release it. Then, the piston rods of the two second linear drive members 356 extend outwards, stopping at a predetermined point in their stroke. At this point, the shuttle has completely passed through the cable. The horizontal drive assembly 33 operates, causing the shuttle that has just completed the insertion and weaving action to move away from the cable insertion and weaving point, and return to its starting point, stopping when it reaches the predetermined insertion and weaving endpoint. During this process, the piston rod of the second linear drive 356 retracts, aligning the second jaw 3542 in the upper and lower shuttle clamping rod assembly 355 with the cable axis. At this time, under the traction of the piston rod of the first linear drive 225, the first gripper 224 in all strand clamping and positioning components 22 moves towards and passes the insertion point. When it reaches the predetermined insertion end position, the proximity detection switch 227 in the corresponding strand clamping and positioning component 22 senses the sensing point on the upper and lower shuttle clamping rod assembly 355 and stops. The second gripper 3542 moves towards the first gripper 224 under the traction of the cylinder extension. It stops when the outer annular groove on one side of the shuttle corresponds to the first gripper 224. The first gripper 224 clamps the shuttle, and the second gripper 3542 releases the shuttle and is pulled back to a certain point in the middle of its stroke under the traction of the second linear drive 356. Under the traction of the horizontal drive assembly 33, it returns to the starting point of its stroke. At this time, under the traction of the piston rod of the first linear drive 225, the first gripper 224 in all strand clamping and positioning components 22 continues to move away from the insertion point, eventually forming the same inclined radial state as the initial state.

[0071] Driven by the rotation drive assembly 34, the rotating assembly 32 makes the second clamp 3542 in the upper shuttle clamping rod assembly 354 or the lower telescopic clamping rod assembly coplanar with the shuttle of the next inserted strand in the plane passing through the cable axis. The strands are inserted in sequence according to a predetermined order and the insertion requirements of strands with different helical directions S and Z in the cable, and finally the entire insertion process is completed.

[0072] The cable braiding device of this invention spreads out the strands of the cable at one end according to the required braiding length, bends a collar according to the product collar size requirements, and fixes the ends of the spread strands to the cable. One end of the cable collar is fixedly clamped to a first end clamping mechanism 1 on one side, the cable is straightened, and the other end of the cable is fixed to a second end clamping mechanism 4. The strand control mechanism 2 clamps the ends of each spread strand through multiple strand clamping and positioning components 22, and the braiding mechanism 3 sequentially clamps the ends of each strand for braiding, thereby realizing the braiding of the cable, saving labor and improving efficiency. Furthermore, through the cable braiding device of this invention, the tension on each strand is consistent during the braiding process, resulting in a tight structure at the braiding point and ensuring the overall strength of the cable after braiding.

[0073] Both ends of the cable are clamped and fixed by the first end clamping mechanism 1 and the second end clamping mechanism 4, respectively, maintaining the cable in a stable state of near-rigidity during the insertion process. The strand control mechanism 2 arranges the strands of the cable radially within a certain radial section of the cable and applies a certain tension to each strand, keeping the strands to be inserted taut; at the same time, it ensures that the force on each strand is consistent during the insertion process. The insertion mechanism 3 adopts a rotary symmetrical bidirectional insertion structure to complete the insertion of S and Z double-twist cables.
