Description

Technical Field

[0001] This invention belongs to the field of wire harness technology, specifically a wire harness stranding device with protective function for automobiles. Background Technology

[0002] A wire harness is a bundle of multiple wires or cables bound together, while a stranded wire is a bundle of multiple wires or cables twisted together to form a braided shape. The process of bundling the wires together prevents the braided bundle from unraveling and makes the wiring inside the equipment simpler and clearer.

[0003] A patent with publication number CN219246447U discloses an automotive wiring harness stranding device, including a base, an mounting block on the upper left side of the base, fixing seats on both the front and rear sides of the mounting block, a movable groove inside the mounting block, a movable block inside the movable groove, a second spring connected to the left side wall of the movable groove, the right end of the second spring connected to the left end of the movable block, a receiving groove on the left side of the movable block, a clamping block inside the receiving groove, a third spring connected to the left side wall of the receiving groove, the right end of the third spring connected to the left end of the clamping block, a placement block connected to the right side of the movable block, two clamping blocks on the upper part of the placement block, and a driving mechanism on the base, which drives the clamping column to rotate. This patent effectively fixes the terminals at both ends of the wiring harness, preventing them from coming loose during the stranding process, ensuring the normal stranding of the wiring harness and the quality of the stranded wire.

[0004] In the aforementioned prior art, during the twisting process, since the distance between the wire feeding assembly and the twisting assembly is fixed and the wire feeding assembly cannot be moved, some untwisted automotive wires will be generated between the wire feeding assembly and the twisting assembly when the twisting is completed, resulting in waste of these automotive wires and affecting the simplicity of the wiring. After the automotive wires are twisted, it is inconvenient to immediately bundle them, which will cause some automotive wires to come apart.

[0010] Preferably, the T-shaped support block has a groove at the end away from the mounting plate, and two T-shaped clamps are slidably connected in the inner cavity of the groove. A miniature electric push rod is provided in the inner cavity of the groove, and the miniature electric push rod is fixedly connected to the T-shaped clamps through its output end.

[0011] Preferably, a toothed ring is fixedly connected to the outside of the stranded drum, the toothed ring is engaged with a toothed disc, a drive motor is installed inside one side of the rotating frame, and the output shaft of the drive motor is fixedly connected to the toothed disc.

[0012] Preferably, the inner cavity of the fixed frame is rotatably connected to a first gear and a second gear, and the first gear and the second gear are symmetrically arranged in the inner cavity of the fixed frame. The first gear and the second gear are externally meshed with a double-sided toothed belt, and the double-sided toothed belt is provided with rubber anti-slip tooth blocks on its outside.

[0013] Preferably, a servo motor is installed inside one side of the fixed frame, and the servo motor is fixed to a transmission gear through an output shaft. The transmission gear is connected to the first gear and the second gear through a double-sided toothed belt.

[0014] Preferably, a film mounting assembly is provided at the end of the mounting column away from the semi-circular rotating frame, and the film mounting assembly includes a cylinder mounted at one end of the mounting column, with a semi-circular clamping plate provided on the outside of the cylinder.

[0015] Preferably, the cylinder is provided with a limiting groove inside, and a bidirectional threaded rod is rotatably connected to the inner cavity of the limiting groove. Two H-shaped sliding discs are externally threaded to the bidirectional threaded rod.

[0016] Preferably, each of the H-shaped slides has a push rod rotatably connected to its inner cavity. The end of the push rod away from the H-shaped slide is rotatably connected to a fixed block via a rotating shaft. The end of the fixed block away from the push rod is fixedly connected to a semi-circular clamping plate.

[0017] The beneficial effects of this invention are as follows: 1. The automotive wiring harness stranding device with protective function of the present invention, when stranding and bundling automotive wires, drives a rotating frame to rotate inside a support base, thereby adjusting the angle of the stranding drum to facilitate the passing of the automotive wire through the stranding frame. Then, one end of the automotive wire passing through the stranding frame is placed in the inner cavity of the winding frame, and the winding frame drives the automotive wire to wind up simultaneously, causing the stranding drum to drive the stranding frame to rotate, which in turn causes the stranding frame to drive the automotive wire to twist and achieve stranding. Then, a semi-circular rotating frame drives the mounting post to rotate, and waterproof wire bundling tape can be installed on the outside of the mounting post. During the rotation of the semi-circular rotating frame, the mounting post and the waterproof wire bundling tape rotate, thereby using the waterproof wire bundling tape to bind the automotive wire, preventing the stranded automotive wire from unraveling. This also solves the problem that it is inconvenient to immediately bundle the automotive wire after stranding, which causes some of the automotive wire to unravel when bundling is done after the entire automotive wire is stranded.

[0018] 2. The automotive wiring harness stranding device with protective function described in this invention, when stranding automotive wiring harnesses, involves placing one end of the automotive wiring harness passing through the stranding device into the inner cavity of the winding frame, and then using a hinge to rotate and flip the clamping plate. A rubber anti-slip pad is provided at the end of the clamping plate near the inner cavity of the winding frame, allowing the clamping plate to clamp and fix the automotive wiring harness in the inner cavity of the winding frame using the rubber anti-slip pad. Simultaneously, the rubber anti-slip pad also protects the surface of the automotive wiring harness. Then, fastening bolts are used to fix the clamping plate to the winding frame, facilitating the winding frame to work with the clamping plate to wind up the stranded automotive wiring harness, preventing damage that can easily occur when manually dragging the wiring harness during stranding.

[0019] 3. The automotive wiring harness stranding device with protective function of the present invention, before tying the automotive wiring harness, places a waterproof film on the outside of a cylinder, drives a bidirectional threaded rod to rotate, and causes two H-shaped sliding discs driven by the bidirectional threaded rod to slide away from each other in the inner cavity of the limiting groove. This causes the H-shaped sliding discs to drive the semi-circular clamping plate to expand. During the expansion of the semi-circular clamping plate, the inner cavity of the waterproof film is squeezed and fixed to it, thereby facilitating the binding of the automotive wiring harness with waterproof tape.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-7 The present invention provides a technical solution: A protective automotive wiring harness stranding device includes a base 1, a support seat 7 installed on one side of the upper end of the base 1, a rotating frame 21 rotatably connected inside the upper end of the support seat 7, a stranding drum 8 rotatably connected inside the rotating frame 21, a stranding frame 24 fixedly connected inside the stranding drum 8, and a mounting seat 9 fixedly connected to the upper end of the base 1 on one side of the support seat 7. A fixing frame 10 is installed on the upper end of the mounting seat 9, and a wire bundling assembly is provided inside the fixing frame 10. The bundled wire assembly includes four auxiliary rollers 15 rotatably connected in the inner cavity of the fixed frame 10. The four auxiliary rollers 15 are symmetrically arranged at both ends of the inner cavity of the fixed frame 10. A semi-circular rotating frame 16 is rotatably connected in the inner cavity of the fixed frame 10. A mounting post 27 is fixedly connected to one side of the semi-circular rotating frame 16. A support frame 11 is fixedly connected to the upper end of the base 1 on one side of the mounting seat 9. A winding frame 12 is rotatably connected to the inner cavity of the support frame 11. A crank handle 34 is fixedly connected to one end of the winding frame 12 through the support frame 11.

[0024] Specifically, in the existing technology, the terminals at both ends of the wire harness are effectively fixed to prevent them from coming loose during the twisting process, thus ensuring the normal twisting of the wire harness and the quality of the twisted wire. However, after the automotive wire is twisted, it is inconvenient to immediately bundle it, which may cause some of the automotive wires to come apart.

[0025] In this invention, when stranding automotive wiring harnesses, the rotating frame 21 is driven to rotate inside the support base 7, thereby adjusting the angle of the stranding drum 8 to facilitate passing the automotive wiring harness 24 through it. One end of the automotive wiring harness passing through the stranding frame 24 is then placed in the inner cavity of the winding frame 12. Simultaneously, the crank handle 34 is driven to rotate the winding frame 12, causing it to wind the automotive wiring harness. At this time, the stranding drum 8 is driven to rotate, causing the stranding frame 24 to rotate, which in turn causes the stranding frame 24 to twist the automotive wiring harness, thus achieving stranding. Simultaneously, the semi-circular rotating frame 16 is driven to rotate inside the fixed frame 10, and four auxiliary rollers 15 assist the rotation of the semi-circular rotating frame 16. To ensure the smooth rotation of the semi-circular rotating frame 16 and prevent it from detaching from the fixed frame 10, the semi-circular rotating frame 16 drives the mounting post 27 to rotate. Waterproof wire harness tape can be installed on the outside of the mounting post 27. During the rotation of the semi-circular rotating frame 16, the mounting post 27 and the waterproof wire harness tape rotate, thereby using the waterproof wire harness tape to bundle the automotive wires and prevent the twisted automotive wires from coming apart. This solves the problem that it is inconvenient to bundle the automotive wires immediately after the twisting is completed, which causes some automotive wires to come apart.

[0026] like Figures 1 to 3 As shown, a clamping plate 13 is rotatably connected to one side of the inner cavity of the winding frame 12 via a hinge. A rubber anti-slip pad is provided at one end of the clamping plate 13 near the inner cavity of the winding frame 12, and the clamping plate 13 is fixedly installed to the winding frame 12 by means of a fastening bolt provided inside.

[0027] Specifically, when bundling automotive wires, one end of the automotive wire passing through the bundling device is placed in the inner cavity of the winding frame 12. Then, the clamping plate 13 is rotated using a hinge. A rubber anti-slip pad is provided at the end of the clamping plate 13 near the inner cavity of the winding frame 12, so that the clamping plate 13 can clamp and fix the automotive wire in the inner cavity of the winding frame 12 using the rubber anti-slip pad. At the same time, the rubber anti-slip pad can also protect the surface of the automotive wire. Then, the clamping plate 13 is fixed to the winding frame 12 using fastening bolts, so that the winding frame 12 can work with the clamping plate 13 to drive the bundled automotive wire to wind up, preventing the automotive wire from being easily abraded when manually dragged during bundling.

[0028] like Figure 1 , Figure 2 and Figure 6 As shown, a slide rail 2 is installed on one side of the upper end of the base 1. A limiting slide post 33 is fixedly connected to the inner cavity of the slide rail 2. A T-shaped slider 3 is slidably connected to the outside of the limiting slide post 33. A fixing rod 4 is fixedly connected to the upper end of the T-shaped slider 3. A mounting plate 5 is rotatably connected to the upper end of the fixing rod 4. Multiple T-shaped support blocks 6 are fixedly connected to the outside of the mounting plate 5.

[0029] Specifically, in the prior art, during the stranding process, since the distance between the wire feeding assembly and the stranding assembly is fixed and the wire feeding assembly cannot be moved, some unstretched automotive wire will be generated between the wire feeding assembly and the stranding assembly when the stranding is completed, resulting in the waste of this part of the automotive wire. In this invention, when stranding automotive wiring harnesses, the required stranded wiring harnesses are mounted on a T-shaped support block 6. When the stranded wiring harnesses are pulled and wound up, the wiring harnesses pull the mounting disc 5 to move, causing the mounting disc 5 to move the fixing rod 4. At the same time, the fixing rod 4 causes the T-shaped slider 3 to slide outside the limiting slide post 33. This ensures that a portion of the wiring harness is always left on the T-shaped support block 6, which facilitates the later connection of the wiring harnesses on the T-shaped support block 6 to external adapters, making it convenient for the assembly of automotive power supplies. It also solves the problem that the existing wiring assembly and stranding assembly have a fixed spacing, and the wiring assembly cannot move, resulting in some wiring harnesses not being stranded, which leads to the trouble of manual stranding later.

[0030] like Figures 1 to 3 As shown, a groove 35 is provided at the end of the T-shaped support block 6 away from the mounting plate 5. Two T-shaped clamps 37 are slidably connected in the inner cavity of the groove 35. A miniature electric push rod 36 is provided in the inner cavity of the groove 35, and the miniature electric push rod 36 is fixedly connected to the T-shaped clamp 37 through the output end.

[0031] Specifically, when performing stranding and bundling on automotive wires, the automotive wires to be stranded and bundled are installed on the T-shaped support block 6. Then, the output end of the micro electric push rod 36 drives the T-shaped clamping plate 37 to slide closer to each other in the inner cavity of the groove 35, thereby clamping and fixing the automotive wires on the T-shaped support block 6, which facilitates the stranding and bundling device to perform stranding and bundling on the automotive wires.

[0032] like Figure 1 , Figure 4 and Figure 5 As shown, a toothed ring 22 is fixedly connected to the outside of the strand drum 8, and a toothed disc 23 is meshed with the toothed ring 22. A drive motor 26 is installed inside one side of the rotating frame 21, and the output shaft of the drive motor 26 is fixedly connected to the toothed disc 23.

[0033] Specifically, when the car wire is stranded, the output shaft of the drive motor 26 drives the gear disk 23 to rotate. At the same time, the gear disk 23 meshes with the transmission gear ring 23 to rotate, and the gear ring 23 drives the stranding drum 8 to rotate. During the rotation of the stranding drum 8, the car wire in the inner cavity will be stranded. At the same time, one end of the car wire is pulled to move, so that the car wire passes through the inner cavity of the stranding drum 8 and is stranded into a strand.

[0034] like Figure 1 , Figure 5 and Figure 6 As shown, a first gear 17 and a second gear 20 are rotatably connected to the inner cavity of the fixed frame 10, and the first gear 17 and the second gear 20 are symmetrically arranged in the inner cavity of the fixed frame 10. The first gear 17 and the second gear 20 are externally meshed with a double-sided toothed belt 19, and the double-sided toothed belt 19 is provided with rubber anti-slip tooth blocks on its outside.

[0035] Specifically, when bundling automotive wiring harnesses, the double-sided toothed belt 19 is driven to rotate, which in turn drives the first gear 17 and the second gear 20 to rotate. The double-sided toothed belt 19 is provided with rubber anti-slip teeth on its exterior. As the double-sided toothed belt 19 rotates, the rubber anti-slip teeth increase the friction with the semi-circular rotating frame 16, thereby driving the semi-circular rotating frame 16 to rotate within the cavity of the fixed frame 10. At the same time, the semi-circular rotating frame 16 drives the tape to bundle the automotive wiring harnesses.

[0036] like Figure 1 , Figure 5 and Figure 6 As shown, a servo motor 25 is installed inside one side of the fixed frame 10. The servo motor 25 is fixed to a transmission gear 18 through its output shaft. The transmission gear 18 is connected to the first gear 17 and the second gear 20 through a double-sided toothed belt 19.

[0037] Specifically, when bundling automotive wiring harnesses, the output shaft of the servo motor 25 drives the transmission gear 18 to rotate, which in turn drives the double-sided toothed belt 19 to rotate. During the rotation of the double-sided toothed belt 19, the first gear 17 and the second gear 20 are simultaneously driven to rotate. As the double-sided toothed belt 19 rotates, by utilizing the cooperation of the first gear 17 and the second gear 20, the double-sided toothed belt 19 drives the semi-circular rotating frame 16 to rotate within the cavity of the fixed frame 10. At the same time, the semi-circular rotating frame 16 drives the tape to bundle the automotive wiring harnesses, thereby improving the efficiency of automotive wiring harness bundling.

[0038] like Figure 1 and Figure 7 As shown, a film mounting assembly is provided at the end of the mounting column 27 away from the semi-circular rotating frame 16, and the film mounting assembly includes a cylinder 14 installed at one end of the mounting column 27, and a semi-circular clamping plate 32 is provided on the outside of the cylinder 14.

[0039] Specifically, before bundling the automotive wiring harness, a waterproof tape is placed outside the cylinder 14, while the semi-circular clamp 32 is driven away from the cylinder 14 to expand. During the expansion of the semi-circular clamp 32, the inner cavity of the waterproof tape is squeezed and fixed to it, so that the waterproof tape can be used to bind and bundle the automotive wiring harness.

[0040] like Figure 1 and Figure 7 As shown, a limiting groove 38 is provided inside the cylinder 14, and a bidirectional threaded rod 28 is rotatably connected to the inner cavity of the limiting groove 38. Two H-shaped sliding plates 29 are externally threaded to the bidirectional threaded rod 28.

[0041] Specifically, before tying the automotive wiring harness, a waterproof tape is placed outside the cylinder 14, while the bidirectional threaded rod 28 is driven to rotate. The bidirectional threaded rod 28 drives two H-shaped slide plates 29 to slide away from each other in the inner cavity of the limiting slide groove 38. This causes the H-shaped slide plates 29 to drive the semi-circular clamping plate 32 to expand. During the expansion of the semi-circular clamping plate 32, the inner cavity of the waterproof tape is squeezed and fixed to it. This makes it easy to use waterproof tape to bind the wiring harness when tying the automotive wiring harness.

[0042] like Figure 1 and Figure 7 As shown, each of the inner cavities of the H-shaped slide 29 is rotatably connected to a push rod 30. The end of the push rod 30 away from the H-shaped slide 29 is rotatably connected to a fixed block 31 via a rotating shaft. The end of the fixed block 31 away from the push rod 30 is fixedly connected to the semi-circular clamp 32.

[0043] Specifically, before bundling the automotive wiring, the H-shaped slides 29 are driven to move away from each other. During the process of the H-shaped slides 29 moving away from each other, the rotating shaft drives the push rod 30 to move. At the same time, the push rod 30 drives the fixed block 31 to move through the rotating shaft, and the fixed block 31 pushes the semi-circular clamp 32 to expand. During the expansion of the semi-circular clamp 32, the waterproof film is squeezed to fix it, thereby facilitating the installation of the waterproof film and making it easy to bundle the automotive wiring.

[0044] Working principle: When stranding automotive wiring harnesses, the rotating frame 21 is driven to rotate inside the support base 7, thereby adjusting the angle of the stranding drum 8 to facilitate the passage of the automotive wiring harness 24. One end of the automotive wiring harness passing through the stranding frame 24 is then placed inside the winding frame 12. Simultaneously, the crank handle 34 is driven to rotate the winding frame 12, causing it to wind the automotive wiring harness. At this time, the stranding drum 8 is driven to rotate, causing the stranding frame 24 to rotate, which in turn causes the stranding frame 24 to twist the automotive wiring harness. Simultaneously, the semi-circular rotating frame 16 is driven to rotate inside the fixed frame 10, and four auxiliary rollers 15 assist the rotation of the semi-circular rotating frame 16. To ensure the smooth rotation of the semi-circular rotating frame 16 and prevent it from detaching from the fixed frame 10, the semi-circular rotating frame 16 is used to drive the mounting post 27 to rotate. Waterproof wire harness tape can be installed on the outside of the mounting post 27. During the rotation of the semi-circular rotating frame 16, the mounting post 27 and the waterproof wire harness tape are driven to rotate, thereby using the waterproof wire harness tape to bundle the automotive wires and prevent the twisted automotive wires from coming apart. This solves the problem that it is inconvenient to bundle the automotive wires immediately after the twisting is completed, which causes some automotive wires to come apart. When bundling automotive wires, one end of the automotive wire passing through the bundling device is placed in the inner cavity of the winding frame 12. Then, the clamping plate 13 is rotated by the hinge to flip it. A rubber anti-slip pad is provided at one end of the clamping plate 13 near the inner cavity of the winding frame 12. The clamping plate 13 uses the rubber anti-slip pad to clamp and fix the automotive wire in the inner cavity of the winding frame 12. At the same time, the rubber anti-slip pad can also protect the surface of the automotive wire. Then, the clamping plate 13 is fixed to the winding frame 12 with the fastening bolts. This makes it easier for the winding frame 12 to work with the clamping plate 13 to drive the bundled automotive wire to wind up, preventing the automotive wire from being easily abraded when manually dragged during bundling. When stranding automotive wiring harnesses, the required stranded automotive wires are mounted on the T-shaped support block 6. When the stranded automotive wire is pulled and wound up, it pulls the mounting disc 5, causing the mounting disc 5 to move and the fixing rod 4 to move. Simultaneously, the fixing rod 4 causes the T-shaped slider 3 to slide outside the limiting slide post 33, ensuring that a portion of the automotive wire is always left on the T-shaped support block 6. This facilitates the later connection of external adapters to the reserved automotive wires on the T-shaped support block 6, simplifying the assembly of the automotive power supply. The stranding process involves mounting the required stranded automotive wires on the T-shaped support block 6 and then using the output end of the miniature electric push rod 36 to drive... The movable T-shaped clamps 37 slide close to each other in the inner cavity of the groove 35, thereby clamping and fixing the automotive wires on the T-shaped support block 6. This facilitates the stranding device to perform stranding and bundling of the automotive wires. Before bundling the automotive wires, a waterproof tape is placed outside the cylinder 14, while the bidirectional threaded rod 28 is driven to rotate. The bidirectional threaded rod 28 drives two H-shaped slide plates 29 to slide away from each other in the inner cavity of the limiting slide groove 38. This causes the H-shaped slide plates 29 to drive the semi-circular clamp 32 to expand. During the expansion of the semi-circular clamp 32, the inner cavity of the waterproof tape is squeezed and fixed to it. This makes it easy to use waterproof tape to bind and bundle the automotive wires when bundling them.
