Description

Technical Field

[0001] This invention relates to the field of stranding machine technology, specifically a multi-axis stranding machine for wire harness production. Background Technology

[0002] A stranding machine is a core piece of equipment in the wire and cable industry. It refers to a mechanical device that uses a rotating body to spirally twist multiple single conductors into one or more strands at a set pitch to meet the process requirements for the flexibility, conductivity, and mechanical strength of the wire.

[0003] In the current field of wire harness processing and production, traditional stranding equipment generally suffers from problems such as simple structural design, low functional integration, and fixed operation mode, making it difficult to meet the needs of modern wire harness high-efficiency, high-precision, and continuous production. Most existing stranding devices only have a single orbital stranding function and cannot achieve flexible switching between single-axis independent rotation and overall orbital stranding. When processing multi-axis wire harnesses, it is difficult to complete the compatible operation of single-axis sequential positioning and clamping of wire harnesses and multi-axis synchronous stranding. This results in the separation of wire harness clamping, tension adjustment, and stranding processes, which cannot be completed in an integrated manner on the same equipment, seriously affecting production continuity and operation efficiency.

[0004] Therefore, we propose a multi-axis stranding machine for wire harness production to solve the problems mentioned above. Summary of the Invention

[0021] 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.

[0022] Please see Figure 1-16 This invention provides a technical solution: a multi-axis stranding machine for wire harness production, comprising a base 1 and a rotating assembly 2, fixedly installed on one side of the outer surface of the base 1 for stranding the wire harness. The rotating assembly 2 includes an internal gear ring 201, an external gear ring 202 fixedly sleeved on the outer surface of the internal gear ring 201, a fixed box 208 movably sleeved on the outer surface of the external gear ring 202, a rotating plate 203 rotatably connected to the inner wall of the fixed box 208, and a plurality of circumferentially evenly arranged fixed shafts 204 movably embedded in the inner wall of the rotating plate 203. Helical gears 205 are movably sleeved on the outer surfaces of the plurality of fixed shafts 204. A first toothed clutch 206 is connected to a keyway near one end of the outer surface; a switching power assembly 3 is located inside the rotating assembly 2. The switching power assembly 3 includes a motor 301, an output shaft 302 is fixedly connected to the output end of the motor 301, a first toothed clutch ring 303 is connected to a keyway near one end of the outer surface of the output shaft 302, a second circular slide plate 304 is movably sleeved on the outer surface of the first toothed clutch ring 303, a moving rod 305 is fixedly installed on the outer surface of the second circular slide plate 304 near one edge, and limit blocks 306 are fixedly connected to the outer surface of the moving rod 305 near both edges. A first gear 307 is fixedly sleeved on the surface; a clamping assembly 4 is fixedly installed on one side of the outer surface of the rotating assembly 2 for fixing the wire harness to be twisted; a driven clamping assembly 5 is set on the other side of the outer surface of the base 1; a support plate 308 is fixedly connected to one side of the outer surface of the fixed box 208; a hydraulic rod 309 is fixedly installed on one side of the outer surface of the support plate 308; a driven plate 310 is fixedly connected to one end of the hydraulic rod 309; a magnet 311 is movably embedded in one side of the inner wall of the driven plate 310; a drive shaft 312 is movably embedded in one side of the inner wall of the fixed box 208; and a fixed sleeve is installed on the outer surface of the drive shaft 312. A second toothed ring 313 is provided, and a second gear 314 is fixedly sleeved on the outer surface of the transmission shaft 312 near the center. The outer surface of the first gear 307 meshes with the outer surface of the second gear 314. The clamping assembly 4 includes multiple cylinders 401. The outer surfaces of the multiple cylinders 401 are movably embedded in the inner wall of the rotating plate 213. One side of the outer surface of the multiple cylinders 401 is fixedly connected to one side of the outer surface of the multiple helical gears 205 respectively. The other side of the outer surface of the multiple cylinders 401 is fixedly connected to a clamping box 402. The other end of the multiple fixed shafts 204 movably penetrates the inner wall of the clamping box 402 and extends into the interior.

[0023] In this embodiment, during use, the operator places multiple wire bundles to be twisted between two corresponding clamping plates 408 in the clamping assembly 4 to prepare for subsequent clamping and twisting. At this time, the motor 301 is started, and it begins to run, driving its output shaft 302 to rotate at high speed. Simultaneously, the rotation of the output shaft 302 drives the first toothed ring 303 connected to its outer surface via a sliding key and the fixedly sleeved first gear 307 to rotate together. When the first gear 307 rotates, it generates a transmission effect on the second gear 314 meshing with it, thereby driving the second gear 314 to rotate as well. The rotation of the second gear 314 then drives the... The drive shaft 312, which is fixedly sleeved on the inner wall, rotates together with the drive shaft 312, which drives the second toothed ring 313, which is fixedly sleeved on its outer side, to rotate synchronously, preparing for subsequent power switching transmission. At this time, the hydraulic rod 309 is activated, and the hydraulic rod 309 begins to extend and retract, driving the driven plate 310 at its end to move axially. When the driven plate 310 moves, it will synchronously drive the magnetic column 311, which is movably embedded in the inner wall on one side, to move together. During the movement, the magnetic column 311 forms a stable magnetic attraction relationship with the second circular slide plate 304 and one of the first sliding circular plates 207 at its two ends, respectively. When the magnetic column 311 drives the second circular slide plate 304 to move, the second circular slide plate 304... 04 will simultaneously drive the first toothed ring 303, causing the inner wall of the first toothed ring 303 to slide axially along the outer surface of the output shaft 302, thereby disengaging the first toothed ring 303 from the second toothed tooth 211; when the magnet post 311 drives one of the first sliding discs 207 to move, the first sliding disc 207 will simultaneously drive the first toothed tooth 206, causing the inner wall of the first toothed tooth 206 to slide axially along the outer surface of the fixed shaft 204, thereby achieving the engagement of the first toothed tooth 206 with the second toothed ring 313. When the first toothed tooth 206 and the second toothed ring 313 are engaged, the power of the transmission shaft 312 will be transmitted through the second toothed ring 311. 3. The transmission is transmitted to the first tooth 206, which in turn drives the fixed shaft 204 to rotate. At the same time, when the fixed shaft 204 rotates, the clamping assembly 4 clamps the stranded wire. The hydraulic rod 309 performs a reverse extension and retraction action and drives the driven plate 310 at its end to move. When the driven plate 310 moves, it will simultaneously drive the magnet 311 embedded in its inner wall to move together. When the magnet 311 drives the second circular slide plate 304 to move, the second circular slide plate 304 will simultaneously drive the first tooth ring 303, so that the inner wall of the first tooth ring 303 slides axially along the outer surface of the output shaft 302, thereby realizing the meshing of the first tooth ring 303 and the second tooth 211.When the magnet post 311 moves one of the first sliding discs 207, the first sliding disc 207 simultaneously moves the first toothed tooth 206, causing the inner wall of the first toothed tooth 206 to slide axially along the outer surface of the fixed shaft 204, thereby disengaging the first toothed tooth 206 from the second toothed ring 313. At this time, the first toothed ring 303 is mostly engaged with the second toothed tooth 211, while the inner wall of the limiting block 306 is not in contact with the corresponding second toothed tooth 211. When the first toothed ring 303 engages with the second toothed tooth 211, the power of the output shaft 302 will be transmitted through... The first toothed insert 303 transmits power to the second toothed insert 211, which in turn drives the rotary shaft 209 to rotate. The rotary shaft 209 drives the driven gear 210 to rotate. The driven gear 210 meshes with the outer gear ring 202, driving the outer gear ring 202 and the inner gear ring 201 to rotate. When the inner gear ring 201 rotates, it drives the helical gear 205 to rotate. Since the rotating plate 203 is not fixed at this time, the outer surface of the helical gear 205 will rotate and revolve along the inner wall of the inner gear ring 201 until the next first toothed insert 206 is located at the second toothed insert 313 and is coaxial with the second toothed insert 313. The same process is repeated, using clamping plates 408 to clamp multiple wire harnesses. When all clamping plates 408 have clamped the wire harnesses, the first toothed ring 303 and the second toothed ring 211 are fully engaged. At this time, the limiting block 306 is in contact with the inner wall of two corresponding limiting holes 212, restricting the rotation of the rotating plate 203. Then, the driven gear 210 drives the outer gear ring 202 to rotate. When the outer gear ring 202 drives the inner gear ring 201 to rotate, it will drive the helical gear 205 to rotate. When the helical gear 205 rotates, it will drive the outer cylinder 401 to rotate. The rotation of the clamping plate 408, in turn, causes the wire harness to rotate, thus stranding the wire harness. This invention achieves rapid switching of the power path by switching the cooperation between the power component 3 and the rotating component 2, using the hydraulic rod 309 to drive the magnetic column 311 to drive the jaw engagement structure. It can freely switch between single-axis self-rotation clamping and overall revolution stranding modes, eliminating the need for manual tooling changes and structural adjustments. It can complete the sequential positioning and clamping of multi-axis wire harnesses in steps, and simultaneously perform multi-axis stranding actions, integrating clamping, adjustment, and stranding processes on the same equipment, significantly improving the continuity and efficiency of wire harness production.

[0024] like Figure 1-16As shown, the other ends of multiple fixed shafts 204 are all fixedly connected to worm gears 403 inside the clamping box 402. Two opposing first connecting shafts 404 are movably embedded between the opposing inner walls of the multiple clamping boxes 402. Worm gears 405 are fixedly sleeved on the outer surfaces of the multiple first connecting shafts 404 near their centers. Each pair of worm gears 405 forms a group, and the outer surfaces of the multiple groups of worm gears 405 mesh with the outer surfaces of the multiple worm gears 403. First rotating rods 406 are fixedly sleeved on the outer surfaces of the multiple first connecting shafts 404 near both ends. Each pair of first rotating rods 406 forms a group, and each group of first rotating rods... A second connecting shaft 407 is movably embedded between the inner walls of the rod 406 near one edge. A clamping plate 408 is movably fitted onto the outer surface of each of the multiple second connecting shafts 407. A third connecting shaft 409 is fixedly embedded near the center of the inner wall of each of the multiple clamping plates 408. A second rotating rod 410 is movably fitted onto the outer surface of each of the multiple third connecting shafts 409 near both ends. The multiple second rotating rods 410 are grouped in pairs. A fourth connecting shaft 411 is movably embedded between the inner walls of each group of second rotating rods 410 near one edge. The multiple fourth connecting shafts 411 are grouped in pairs. The two ends of each group of fourth connecting shafts 411... The driven clamping assembly 5 is movably embedded between the opposing inner walls of multiple clamping boxes 402. It includes a clamping slide plate 501, the outer surface of which is rotatably connected to one side inner wall of the machine base 1. The outer surface of the clamping slide plate 501 has multiple evenly arranged circular holes 502. Support plates 503 are fixedly connected to the outer surface of the clamping slide plate 501 near each of the circular holes 502. Two springs 504 are provided on the outer surface of each support plate 503. A fixing rod 509 is fixedly connected to the center of one side outer surface of the clamping slide plate 501, and one end of the fixing rod 509 is fixedly connected to the center of one side outer surface of the rotary plate 213. The connection consists of multiple springs 504 arranged in pairs. One end of each set of springs 504 is fixedly connected to the outer surface of multiple support plates 503. The other end of each set of springs 504 is fixedly connected to a sliding plate 505. The outer surface of each sliding plate 505 is slidably connected to the outer surface of multiple support plates 503. A first rubber pad 506 is fixedly connected to one side of the outer surface of each sliding plate 505. A fixing block 508 is fixedly connected to one side of the outer surface of each clamping sliding plate 501 near the first rubber pad 506. A second rubber pad 507 is fixedly connected to one side of the outer surface of each fixing block 508 near the first rubber pad 506.

[0025] In this embodiment, during use, the operator places multiple wire harnesses to be twisted between two corresponding clamping plates 408 in the clamping assembly 4 to prepare for subsequent clamping and twisting. The hydraulic rod 309 is then activated, extending and retracting to engage the first tooth 206 with the second toothed ring 313. When the first tooth 206 and the second toothed ring 313 are engaged, the power from the drive shaft 312 is transmitted to the first tooth 206 through the second toothed ring 313, thereby rotating the fixed shaft 204. Simultaneously, the rotation of the fixed shaft 204 causes the worm gear 403 at its end to rotate. The worm gear 403 meshes with the worm wheel 405, driving the first connecting shaft 404 to rotate. The first connecting shaft 404 causes the first rotating rod 406 to swing. The first rotating rod 406, through the second connecting shaft 407, drives the clamping plates 408 to move, ensuring the two clamping plates 408 stably clamp the wire harnesses. The ends of the wire harnesses pass through the clamping plates. The circular hole 502 on the slide plate 501 pushes the slide plate 505 inward to compress the spring 504, causing the first rubber pad 506 and the second rubber pad 507 to separate. The end of the wire harness is placed between the first rubber pad 506 and the second rubber pad 507. The slide plate 505 is released, and the wire harness is elastically clamped under the combined action of the support plate 503, the spring 504, the slide plate 505, the first rubber pad 506, the fixing block 508, and the second rubber pad 507. The wire harness rotates synchronously with the clamping slide plate 501, keeping the wire harness straight and taut. This invention uses a multi-stage precision transmission combination of internal gear ring 201, helical gear 205, worm gear 405, and worm 403, which ensures smooth power transmission and accurate transmission ratio. The clamping assembly 4 adopts a linkage clamping structure, which can realize stable and reliable clamping of the wire harness. Multi-axis synchronous rotation and twisting can ensure that the wire harness twisting pitch is uniform and the tension is constant and controllable, which greatly improves the wire harness twisting accuracy and the finished product qualification rate, meeting the requirements of high-precision wire harness production.

[0026] like Figure 1-16 As shown, a first sliding plate 207 is movably fitted on the outer surface of multiple first toothed teeth 206. A rotating shaft 209 is movably fitted on one side inner wall of the fixed box 208. A driven gear 210 is fixedly fitted on the outer surface of the rotating shaft 209 near the center. The outer surface of the driven gear 210 meshes with the outer surface of the outer gear ring 202. A second toothed tooth 211 is fixedly fitted on the outer surface of the rotating shaft 209 near one end. Multiple circumferentially evenly arranged limiting holes 212 are opened on one side outer surface of the rotating plate 203. A circular rotating plate 213 is rotatably connected to one side inner wall of the fixed box 208. The outer surface of the fixed box 208 is fixedly connected to one side outer surface of the machine base 1. One side outer surface of the rotating plate 203 is in contact with one side outer surface of the outer gear ring 202. The outer surfaces of multiple helical gears 205 are movably meshed with the inner wall of the inner gear ring 201. The outer surface of the motor 301 is fixedly connected to the outer surface of the fixed box 208 by screws.

[0027] In this embodiment, when in use, the hydraulic rod 309 is activated, and the hydraulic rod 309 begins to extend and retract, driving the driven plate 310 at its end to move axially. When the driven plate 310 moves, it will simultaneously drive the magnetic column 311 embedded in the inner wall of one side to move as well. During the movement, the magnetic column 311 forms a stable magnetic attraction relationship with the second circular slide plate 304 and one of the first sliding circular plates 207 at its two ends respectively. When the magnetic column 311 drives the second circular slide plate 304 to move, the second circular slide plate 304 will simultaneously drive the first toothed ring 303, causing the inner wall of the first toothed ring 303 to slide axially along the outer surface of the output shaft 302, thereby realizing the disengagement of the first toothed ring 303 from the second toothed teeth 211.When the hydraulic rod 309 performs a reverse extension and retraction action, it drives the driven plate 310 at its end to move. When the driven plate 310 moves, it simultaneously drives the magnet 311, which is movably embedded in the inner wall of one side, to move as well. When the magnet 311 drives the second circular slide plate 304 to move, the second circular slide plate 304 simultaneously drives the first toothed ring 303, causing the inner wall of the first toothed ring 303 to slide axially along the outer surface of the output shaft 302. At this time, the first toothed ring 303 is mostly engaged with the second toothed teeth 211, and the power of the output shaft 302 is transmitted through the first toothed ring 303. The transmission is transferred to the second tooth 211, which in turn drives the rotary shaft 209 to rotate. The rotary shaft 209 drives the driven gear 210 to rotate. The driven gear 210 meshes with the outer gear ring 202, driving the outer gear ring 202 and the inner gear ring 201 to rotate. When the inner gear ring 201 rotates, it drives the helical gear 205 to rotate. Since the rotating plate 203 is not fixed at this time, the outer surface of the helical gear 205 will rotate and revolve along the inner wall of the inner gear ring 201. In conjunction with the driven clamping assembly 5, the fixed rod 509 is connected through the circular rotating plate 213. The fixed rod 509 will drive the clamping slide plate 501. Synchronous follow-up is performed until the next first toothed clamping tooth 206 is located at the second toothed clamping ring 313 and is coaxial with the second toothed clamping ring 313. At this time, the same process is repeated, using the clamping plate 408 to clamp multiple wire harnesses. When all the clamping plates 408 have clamped the wire harnesses, the first toothed clamping ring 303 and the second toothed clamping tooth 211 are fully engaged. At this time, the limiting block 306 is in contact with the inner wall of two corresponding limiting holes 212 to limit the rotation of the rotating plate 203. At this time, the driven gear 210 drives the external gear ring 202 to rotate. When the ring 202 drives the internal gear ring 201 to rotate, it drives the helical gear 205 to rotate. At this time, the rotation of the helical gear 205 drives the external cylinder 401 to rotate, which in turn drives the clamping plate 408 to rotate, thus twisting the wire harness. This invention achieves precise positioning and rotation restriction of the rotating plate 203 through the cooperation of the limiting block 306 and the limiting hole 212, avoiding lateral movement and misalignment during rotation. Simultaneously, the use of a magnetic attractor column 311 to drive the sliding component displacement reduces frictional loss between components, effectively extending the equipment's service life and reducing later maintenance costs and equipment failure rate.

[0028] The usage and working principle of this device are as follows: During use, the operator places multiple wire bundles to be twisted between two corresponding clamping plates 408 in the clamping assembly 4, preparing for subsequent clamping and twisting. At this time, the motor 301 is started, and it begins to run, driving its output shaft 302 to rotate at high speed. Simultaneously, the rotation of the output shaft 302 drives the first toothed ring 303 connected to its outer surface via a sliding key and the fixedly sleeved first gear 307 to rotate together. When the first gear 307 rotates, it generates a transmission effect on the second gear 314 meshing with it, thus driving the second gear 314 to rotate as well. The rotation of the second gear 314 then drives the transmission shaft 312 fixedly sleeved on its inner wall to rotate together. During rotation, the outer surface of the transmission shaft 312 rotates stably on the inner wall of the fixed box 208, maintaining the transmission... To ensure smooth operation, the transmission shaft 312 will drive the second toothed ring 313 fixedly sleeved on its outside to rotate synchronously, preparing for subsequent power switching transmission. At this time, the hydraulic rod 309 is activated, and the hydraulic rod 309 begins to extend and retract, driving the driven plate 310 at its end to move axially. When the driven plate 310 moves, it will synchronously drive the magnet 311 movably embedded on one side of its inner wall to move together. During the movement, the magnet 311 forms a stable magnetic attraction relationship with the second circular slide plate 304 and one of the first sliding circular plates 207 at its two ends respectively. When the magnet 311 drives the second circular slide plate 304 to move, the second circular slide plate 304 will synchronously drive the first toothed ring 303, so that the inner wall of the first toothed ring 303 slides axially along the outer surface of the output shaft 302, thereby realizing the disengagement of the first toothed ring 303 from the second toothed ring 211.When the magnet post 311 moves one of the first sliding discs 207, the first sliding disc 207 simultaneously moves the first toothed gear 206, causing the inner wall of the first toothed gear 206 to slide axially along the outer surface of the fixed shaft 204. This achieves engagement between the first toothed gear 206 and the second toothed ring 313. When the first toothed gear 206 and the second toothed ring 313 are engaged, the power of the drive shaft 312 is transmitted to the first toothed gear 206 through the second toothed ring 313, thereby driving the fixed shaft 204. 4. Rotation: Simultaneously, the rotation of the fixed shaft 204 drives the worm 403 at its end to rotate. The worm 403 meshes with the worm wheel 405, driving the first connecting shaft 404 to rotate. The first connecting shaft 404 drives the first rotating rod 406 to swing. The first rotating rod 406 drives the clamping plate 408 to move through the second connecting shaft 407, so that the two clamping plates 408 stably clamp the wire harness. The end of the wire harness passes through the round hole 502 on the clamping slide plate 501, pushing the slide plate 505 inward to compress the spring 504, causing the first rubber pad 50... 6. Separate from the second rubber pad 507, place the end of the wire harness between the first rubber pad 506 and the second rubber pad 507, release the sliding plate 505, and under the combined action of the support plate 503, spring 504, sliding plate 505, first rubber pad 506, fixing block 508, and second rubber pad 507, it is elastically clamped and rotates synchronously with the clamping sliding plate 501, keeping the wire harness straight and taut. When the stranding operation reaches the preset stranding pitch and length, and when other clamping plates 408 are needed to clamp the stranded wire, At this time, the hydraulic rod 309 performs a reverse extension and retraction action and drives the driven plate 310 at its end to move. When the driven plate 310 moves, it will simultaneously drive the magnet 311 embedded in the inner wall on one side to move together. When the magnet 311 drives the second circular slide plate 304 to move, the second circular slide plate 304 will simultaneously drive the first toothed ring 303, so that the inner wall of the first toothed ring 303 slides axially along the outer surface of the output shaft 302, thereby realizing the meshing of the first toothed ring 303 and the second toothed tooth 211.When the magnet post 311 moves one of the first sliding discs 207, the first sliding disc 207 simultaneously moves the first toothed tooth 206, causing the inner wall of the first toothed tooth 206 to slide axially along the outer surface of the fixed shaft 204, thereby disengaging the first toothed tooth 206 from the second toothed ring 313. At this time, the first toothed ring 303 is mostly engaged with the second toothed tooth 211, while the inner wall of the limiting block 306 is not in contact with the corresponding second toothed tooth 211. When the first toothed ring 303 meshes with the second toothed tooth 211, the power of the output shaft 302 is transmitted to the second toothed tooth 211 through the first toothed ring 303, thereby driving the rotary shaft 209 to rotate. The rotary shaft 209 drives the driven gear 210 to rotate. The driven gear 210 meshes with the outer gear ring 202, driving the outer gear ring 202 and the inner gear ring 201 to rotate. When the inner gear ring 201 rotates, it drives the helical gear 205 to rotate. Since the rotating plate 203 is not fixed at this time, the outer gear 205 rotates. The surface will rotate and revolve along the inner wall of the internal gear ring 201. In conjunction with the driven clamping assembly 5, a fixed rod 509 is connected via a rotating plate 213. The fixed rod 509 will drive the clamping slide plate 501 to move synchronously until the next first tooth 206 is located at the second tooth ring 313 and is coaxial with it. At this point, the same process is repeated, using the clamping plate 408 to clamp multiple wire harnesses. When multiple clamping plates 408 have clamped the wire harnesses, the first tooth ring... When 303 and the second tooth 211 are fully engaged, the limiting block 306 is in contact with the inner wall of two corresponding limiting holes 212, restricting the rotation of the rotating plate 203. At this time, the driven gear 210 drives the outer gear ring 202 to rotate. When the outer gear ring 202 drives the inner gear ring 201 to rotate, it drives the helical gear 205 to rotate. The rotation of the helical gear 205 then drives the outer cylinder 401 to rotate, which in turn drives the clamping plate 408 to rotate, thus twisting the wire harness.
