Description

Technical Field

[0001] This invention relates to the field of wire cutting device technology, specifically a multi-specification wire fixed-length cutting device for wire harness processing. Background Technology

[0002] In the wire harness manufacturing process of automotive, new energy, aerospace, and precision electronics industries, wire length cutting is a core preliminary step to ensure the assembly accuracy, electrical performance, and stability of subsequent wire stripping and crimping processes. As end products develop towards a more diverse and customized direction, the wire specifications that wire harness processing needs to adapt to are becoming increasingly diverse, covering copper core and aluminum core flexible wires of different diameters, as well as insulation layers of different materials such as PVC and XLPE. Moreover, the requirements for cutting length accuracy (≤±0.1mm), cut smoothness (no burrs, no exposed wire core, no fraying), and changeover efficiency (≤3 minutes) are constantly increasing.

[0003] Currently, mainstream wire length cutting devices in the industry generally employ a sliding cutting structure. This structure typically consists of a flat blade on one side and an inclined blade on the other, achieving shearing through relative sliding when the upper and lower blades approach each other. However, this sliding cutting design can only match a narrow range of wire diameters (typically ≤2mm diameter difference), relying on line contact between the wire diameter and the inclined surface of the blade for positioning. For ultra-fine wires below 0.5mm, lateral shifting and slippage are prone to occur due to insufficient positioning surface; for thicker wires above 4mm, uneven contact pressure distribution leads to insecure clamping, resulting in axial movement during cutting. The sliding cutting method relies on the sliding friction of the inclined surface of the blade to achieve cutting, which generates lateral compressive force on the wire during the process, causing plastic deformation or axial movement in soft wires. The cutting length error is generally greater than ±0.3mm. Another technology proposes to use a single V-shaped groove interlocking cutting structure, but the traditional V-shaped groove is a fixed size design, which cannot simultaneously meet the needs of preventing thin wires from bending and accurately positioning thick wires. When cutting thin wires, they are prone to bending downwards along the groove wall, affecting subsequent horizontal conveying. For thick wires, the groove shape is not adapted enough, resulting in positioning deviation. Summary of the Invention

[0004] The purpose of this invention is to provide a wire harness processing multi-specification wire length cutting device that facilitates improved stability when cutting wires of different specifications, thereby solving the problems mentioned in the background art.

[0018] 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.

[0019] Example 1: Please refer to Figures 1-8The wire harness processing multi-specification wire length cutting device shown in the figure includes a body 1, a cutting mechanism, and a support and cleaning mechanism. A fixed frame 2 is fixedly connected to the upper side of the body 1. Multiple sets of slope blocks 40 that can be slidably adjusted and guide and position wires 41 of different specifications are slidably connected to the upper side of the body 1. The cutting mechanism includes a cutting blade 3 installed below the fixed frame 2. A first lifting plate 4 is provided on the body 1. Second lifting plates 5 are slidably connected to both sides of the first lifting plate 4. The side of the second lifting plate 5 away from the first lifting plate 4 slides... The cutting mechanism includes a fixed plate 6, a V-shaped groove 7 at the upper end of the first lifting plate 4, and extension grooves 8 on both the second lifting plate 5 and the fixed plate 6. The slope of the extension groove 8 is the same as the slope of the sides of the V-shaped groove 7. The cutting mechanism also includes a hydraulic rod 37 fixedly mounted on the fixed frame 2. The telescopic end of the hydraulic rod 37 is fixedly connected to a mounting frame 38. The mounting frame 38 is slidably connected to the inner wall of the fixed frame 2 in the vertical direction. The top of the cutting blade 3 is fixedly connected to the mounting frame 38. The cutting mechanism can control the cutting blade 3 to rise and fall. The lowering mechanism completes the cutting of the lower wire 41. Simultaneously, it can adjust the lifting states of the first lifting plate 4 and the second lifting plate 5 according to the different specifications of the wire 41, changing the depth of the groove for positioning the wire 41. This adapts to different specifications of wire 41 for fixed-length cutting. The support and cleaning mechanism is installed on the machine body 1 to fill and support the extension groove 8, and assists in scraping and cleaning impurities from the inner walls of the V-shaped groove 7 and the extension groove 8. The initial V-shaped groove 7 in the middle position positions and guides the wire 41 with a smaller diameter, preventing the groove from being too large and causing significant bending at the end of the wire 41. The outer edge of the upper cutting blade 3 is also V-shaped, and the bottom of the cutting blade 3 is vertically aligned with the bottom of the V-shaped groove 7. This allows the wire 41 to be pressed down into the V-shaped groove 7 from the center for positioning during the cutting process, and the cutting is completed as the cutting blade 3 moves downwards, preventing the wire 41 from deviating and affecting the cutting length. The cutting blade 3 can be installed and replaced with the mounting bracket 38 using bolts or other fixing structures.

The bottom end of a set of second threaded rods 27 is coaxially fixedly connected to the second gear 29 that meshes with the first gear 28. The two sets of second threaded rods 27 are connected by a gear belt 30 through a pulley drive. The first motor 23 drives the first threaded rod 25 in the middle to rotate, thereby controlling the lifting and lowering of the first lifting plate 4. The second motor 24 drives the second threaded rods 27 on both sides to rotate, thereby controlling the lifting and lowering of the second lifting plate 5.

[0021] Example 3: Please refer to Figures 2-11This embodiment further illustrates Embodiment 1. The supporting cleaning mechanism shown in the figure includes a first sliding plate 9 that is horizontally connected to the inner wall of the V-shaped groove 7; a second sliding plate 10 that is horizontally connected to the extension groove 8 on the second lifting plate 5; and a third sliding plate 11 that is horizontally connected to the extension groove 8 on the upper side of the fixed plate 6. The machine body 1 is provided with a control component that can control the sliding state of the first sliding plate 9, the second sliding plate 10, and the third sliding plate 11 according to the height of the first lifting plate 4 and the second lifting plate 5. The machine body 1 is provided with a collection component for collecting and processing impurities. The upper edges of the first lifting plate 4, the second lifting plate 5, and the fixed plate 6 are all provided with a horizontal support surface 39. The first sliding plate 9, the second sliding plate 10, and the third sliding plate... The top surface of 11 is flush with the support surface 39. The control components include a first connecting frame 12 fixedly installed between two sets of second sliding plates 10, a second connecting frame 13 fixedly connected between two sets of third sliding plates 11, a docking frame 14 fixedly connected to the end of the first sliding plate 9 away from the first lifting plate 4, a guide groove 15 opened in the docking frame 14, a docking component for driving the docking frame 14 to dock on the body 1, and a driving component for driving the docking frame 14 to slide on the body 1. The docking component includes a first guide block 16 fixedly installed on the side of the first connecting frame 12. The first guide block 16 can be inserted into the inner wall of the guide groove 15 in the horizontal direction and slidably connected in the vertical direction. The side of the second connecting frame 13 is fixedly connected with a component that can be inserted into the inner wall of the guide groove 15. A second guide block 17 is inserted horizontally and slidably connected vertically to the wall. A first stop block 18 for limiting and engaging the first guide block 16 is fixedly connected to the side of the docking frame 14. A second stop block 19 for limiting and engaging the second guide block 17 is fixedly connected to the side of the docking frame 14. The driving component includes an electric telescopic rod 20 fixedly installed on the body 1. A guide frame 21 is fixedly connected to the telescopic end of the electric telescopic rod 20. The guide frame 21 is slidably connected to the surface of the body 1 horizontally. A guide rod 22 is fixedly connected to the side of the docking frame 14. A sliding rod that slides through the first slide plate 9 horizontally can be provided on the side of the docking frame 14 for sliding support. The guide rod 22 is slidably connected to the inner wall of the guide frame 21 vertically. A collecting component... The system includes a collection box 31 that is inserted into the top surface of the body 1. A scraper 32 is slidably connected to the top surface of the body 1 in the horizontal direction. Two sets of fixing blocks 33 are fixedly connected to the upper side of the body 1. A tension spring 34 is fixedly connected to the side of the scraper 32 and fixedly connected to the fixing blocks 33. An insertion block 35 is fixedly connected to the top surface of the first sliding plate 9. An insertion groove 36 is provided on the bottom surface of the scraper 32 so that it can be inserted into the insertion block 35 in the vertical direction. A sliding rod that slides horizontally through the fixing block 33 can be provided on the side of the scraper 32 near the fixing block 33 for sliding guidance. The opening of the collection box 31 is larger than the cross-sectional size of the scraper 32, so that the scraper 32 can be fully inserted into the collection box 31. The first sliding plate 9 is driven to slide horizontally along the inner wall of the V-shaped groove 7 by the electric telescopic rod 20.The system can push impurities adhering to the inner wall of the V-shaped groove 7 towards the collection box 31. When the first lifting plate 4 moves down, the docking frame 14 can dock with the second sliding plate 10, thereby causing the first sliding plate 9 and the second sliding plate 10 to slide together. When the first sliding plate 9 and the second sliding plate 10 move away from the collection box 31, the V-shaped groove 7 on the first lifting plate 4 aligns with the extended groove 8 on the second lifting plate 5, forming a larger V-shaped groove, which can be used to cut and position the wire 41 with a larger diameter. When the first sliding plate 9 and the second sliding plate 10 move towards the collection box 31 at the same time, the entire inner wall of this V-shaped groove can be scraped and cleaned.

[0022] Working principle: The spacing of the two side slope blocks 40 is adjusted according to the diameter of the wire 41 to be cut, so that the wire 41 can fit against the top surface of the machine body 1 and be guided and conveyed by the two side slope blocks 40. The wire 41 is conveyed by the conveying mechanism, so that the length between the end of the wire 41 away from the conveying mechanism and the middle of the first lifting plate 4 is exactly the required cutting length. At this time, the hydraulic rod 37 is controlled to push the mounting frame 38 down, so that the cutting blade 3 moves down to cut the wire 41. The operating status of the first motor 23 and the second motor 24 can be controlled according to the diameter of the wire 41, as shown in the attached figure. Figures 2-4 As shown, at this time, only the V-groove 7 is used for positioning. The first lifting plate 4 and the second lifting plate 5 are both at the top. The second sliding plate 10 and the third sliding plate 11 are respectively located in the extension grooves 8 on both sides for filling. With the support surface 39 at the top of the first lifting plate 4, the second lifting plate 5 and the fixed plate 6, the upper edges of both sides of the V-groove 7 are flush with the surface of the machine body 1. At this time, the wire 41 will not touch the sharp edge during the conveying process, which can better protect the wire 41. During the cutting process, only the V-groove 7 is used for positioning. The first sliding plate 9 is in a position away from the collection box 31. By extending and retracting the electric telescopic rod 20, the guide frame 21 can drive the guide rod 22 and the docking frame 14 to slide horizontally, thereby driving the first sliding plate 9 to slide. At this time, due to the insertion block 35 and The insertion of the slot 36 allows the scraper 32 to slide horizontally along with the first slide plate 9, simultaneously pushing impurities from the support surface 39, the second slide plate 10, and the top surface of the third slide plate 11 into the collection box 31 for collection. A vertical cleaning plate (not shown) can be installed inside the collection box 31 to vertically scrape and remove impurities from the ends of the scraper 32, the first slide plate 9, the second slide plate 10, and the third slide plate 11. When needed, the first slide plate 9 can be controlled to remove impurities from the inner wall of the V-groove 7 to avoid affecting the efficiency of subsequent cutting. Impurities remaining on the inner wall of the V-groove will directly affect the positioning accuracy and cutting quality of the wire 41, leading to cutting size deviation, damage to the wire 41, or positioning offset. During use, the collection box 31 needs to be periodically removed and the impurities stored inside cleaned before being installed on the machine body 1.

[0023] When the diameter of the wire 41 is large, first control the electric telescopic rod 20 to push the first slide plate 9 into the V-groove 7. At this time, the docking frame 14 is in position to fit the first connecting frame 12 and the second connecting frame 13. The first guide block 16 and the second guide block 17 are both horizontally inserted into the guide groove 15. Control the first motor 23 to run and drive the first threaded rod 25 to rotate, thereby driving the first lifting plate 4 to move down through the threaded groove 26, so that the first slide plate 9 drives the docking frame 14 to move down synchronously. During the downward movement of the docking frame 14, the first guide block 16 does not move. Then the first guide block 16 and the second guide block 17 slide upward relative to the docking frame 14. The first stop block 18 slides to the side of the first guide block 16 and blocks the first guide block 16. At this time, the second stop block 19 is still not in position. Sliding to the side of the second guide block 17, the horizontal sliding of the docking frame 14 can only drive the first slide plate 9 and the second slide plate 10 to slide horizontally. The third slide plate 11 is still supported on the upper side of the fixed plate 6. At this time, the large groove combined with the extension groove 8 on the upper side of the second lifting plate 5 is used for positioning, which can position and cut the wire 41 with a larger diameter. At the same time, the extension and retraction of the electric telescopic rod 20 can drive the first slide plate 9 and the second slide plate 10 to slide and scrape. By setting the guide frame 21 and the guide rod 22, the first lifting plate 4 can drive the first slide plate 9 and the docking frame 14 to rise and fall simultaneously during the lifting and lowering process, without affecting the horizontal reciprocating sliding of the first slide plate 9 and the docking frame 14 by the electric telescopic rod 20.

[0024] When the diameter of the wire 41 is further increased, the size of the positioning groove can be further increased. The first sliding plate 9 and the second sliding plate 10 are controlled by the electric telescopic rod 20 to reach above the second lifting plate 5 of the first lifting plate 4. The docking frame 14 is attached to the second connecting frame 13, and the second guide block 17 is inserted into the guide groove 15. The second motor 24 is started to drive the first gear 28 to rotate. The first gear 28 drives the second gear 29, so that the gear belt 30 synchronously drives the second threaded rods 27 on both sides to rotate, thereby controlling the second lifting plate 5 to rise and fall. At this time, the first motor 23 needs to be controlled to run synchronously, so that the first lifting plate 4 and the second lifting plate 5 move down synchronously until the extension groove 8 on the upper side of the second lifting plate 5 and the upper side of the fixed plate 6 are aligned. The slope of the extension groove 8 is on a straight line. At this time, the V-shaped groove 7 in the middle and the two sets of extension grooves 8 on both sides can be combined to form a larger positioning groove to position the large diameter guide. During the downward movement of the first lifting plate 4 and the second lifting plate 5, the first sliding plate 9, the second sliding plate 10 and the docking frame 14 will move down synchronously. At this time, since the second guide block 17 is not moving, the second stop block 19 gradually slides down to the side of the second guide block 17 and blocks the second guide block 17 inside the guide groove 15. After that, during the extension and retraction of the electric telescopic rod 20, the first sliding plate 9, the second sliding plate 10 and the third sliding plate 11 can be driven to slide horizontally synchronously, pushing the impurities inside the large groove into the collection box 31 for collection.

[0025] It is worth noting that when the first slide plate 9 moves down, the insertion block 35 moves down synchronously, releasing its insertion into the insertion slot 36. Subsequently, driven by the tension spring 34, the scraper 32 slides horizontally in the opposite direction to a position close to the fixed block 33 for reset. When the first lifting plate 4 and the second lifting plate 5 move up, the first guide block 16 and the second guide block 17 gradually release their connection with the docking frame 14 and the guide slot 15 and reset under the push of the docking frame 14. The first slide plate 9 needs to move up and reset with the first lifting plate 4 at a position away from the collection box 31, so that the insertion block 35 can be re-inserted into the insertion slot 36 for docking during the upward movement. At this time, although the second slide plate 10 will also move away from the collection box 31... When the collection box 31 stops, the first guide block 16 releases its restriction from the first stop block 18. However, when the first slide plate 9 pushes towards the collection box 31, the docking frame 14 will still push the first connecting frame 12 and the second slide plate 10 above the second lifting plate 5 for reset. It simply won't continue to pull the second slide plate 10 in the opposite direction. The device can then fully reset, making adjustment and switching more flexible and efficient. During reset, the first motor 23 and the second motor 24 need to be started first to drive the first lifting plate 4 and the second lifting plate 5 to move synchronously to the set position, making the top surface of the second lifting plate 5 flush with the top surface of the fixed plate 6. Then, the first motor 23 is controlled separately to rotate, driving the first lifting plate 4 to move to the uppermost position. (Refer to the attached diagram.) Figure 9 -Appendix Figure 11 Limiting grooves need to be set in the V-shaped groove 7 and the extension groove 8 to position and guide the first slide plate 9, the second slide plate 10 and the third slide plate 11 respectively, so as to ensure that they can fit tightly against the inner wall of the V-shaped groove 7 and the extension groove 8 during the sliding process, and that one end will not be lifted up. Moreover, these limiting grooves will not affect the integrity of the overall V-shaped groove, and impurities inside will be pushed and removed. The positioning of the V-shaped groove is achieved by positioning the entire recess. The small grooves inside do not affect the shape of the overall groove, and do not affect the cutting and positioning operation for wires of different specifications.
