Description

Technical Field

[0001] This utility model relates to the field of wire harness stripping machine technology, and in particular to an automotive wire harness stripping machine with adjustable cutting depth. Background Technology

[0002] In today's booming automotive industry, automotive wiring harnesses, as a crucial component of automotive electrical systems, directly impact the overall performance and production schedule of vehicles through their processing quality and efficiency. The wire harness stripping process, a key step in wiring harness manufacturing, aims to precisely remove the outer insulation layer of the wire harness, preparing it for subsequent connection and assembly work.

[0003] Existing automotive wiring harness stripping machines include a U-shaped plate, a cutting assembly, and an adjustment assembly for adjusting the cutting depth of the cutting assembly. The U-shaped plate serves as the support frame for the entire machine, providing a platform for the installation and operation of both the cutting assembly and the adjustment assembly. Both the cutting assembly and the adjustment assembly can be mounted on the U-shaped plate. The cutting assembly has a sliding plate and a cutting seat inside, which is used to fix the automotive wire harness to be stripped. In actual operation, when using an existing wire harness stripping machine, the operator first places the wire harness to be stripped on the cutting seat, and then starts the adjustment assembly. The adjustment assembly drives the cutter inside the cutting assembly to press down. The cutting depth is adjusted by controlling the pressing distance to meet the stripping requirements of different specifications of wire harnesses. When the cutter is pressed down to the appropriate position, the cutter begins to cut the wire harness and complete the removal of the insulation layer. However, there is a serious safety hazard in the design and use of existing wire harness stripping machines—the protection of the cutter. The cutter in the existing device is usually directly installed on the cutting assembly and is exposed to the outside of the equipment most of the time. The cutter of some stripping machines is simply fixed to one side of the cutting seat. After the operator completes the wire harness stripping operation, the cutting cavity needs to be cleaned. However, during the cleaning process, because the cutter is exposed, the operator's hand can easily touch the blade of the cutter unintentionally. A slight carelessness can result in a cut finger, causing inconvenience in actual use.

[0004] Therefore, it is necessary to provide a new automotive wiring harness stripping machine with adjustable cutting depth to solve the above-mentioned technical problems. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figures 1 to 8 ,in, Figure 1 A schematic diagram of the overall structure of the automotive wiring harness stripping machine with adjustable cutting depth provided by this utility model; Figure 2 A schematic diagram of the main structure of the automotive wire harness stripping machine with adjustable cutting depth provided by this utility model; Figure 3 This is a schematic diagram of the second slide.

Figure 8 This is a schematic diagram of the cross-sectional structure of the cavity.

[0021] In some embodiments, such as Figures 1 to 8As shown, the device includes a U-shaped plate 1. A reciprocating cutting assembly is slidably provided on the bottom wall of the U-shaped plate 1. The surface of the reciprocating cutting assembly has multiple cutting parts for cutting different wire harness outer diameters. The apertures of the multiple cutting parts are distributed in a gradually decreasing manner from left to right. The surface of the reciprocating cutting assembly is also provided with an adjustment assembly for adjusting the cutting depth. One end of the adjustment assembly is provided with a cutter 66. A magnet 663 is fixed on the top of the cutter 66. A magnet 654 is provided on the surface of the adjustment assembly. The magnet 654 is magnetically attracted to the magnet 663. The bottom of the adjustment assembly is also provided with a storage assembly for storing the cutter 66. One end of the storage assembly is engaged with the bottom of the adjustment assembly. Specifically, by providing multiple cutting parts on the surface of the reciprocating cutting assembly for cutting different wire harness outer diameters, and with the apertures of the multiple cutting parts gradually decreasing from left to right, the stripping machine can adapt to the stripping needs of automotive wire harnesses with different outer diameters. This eliminates the need for frequent replacement of cutting parts, greatly improving the equipment's versatility. In actual production, when faced with wire harnesses of different specifications, operators only need to select the appropriate cutting part position according to the outer diameter of the wire harness for cutting, reducing equipment downtime and the steps of replacing cutting parts, and significantly improving production efficiency. Furthermore, by providing a storage component at the bottom of the adjustment assembly for storing the cutter 66, with one end of the storage component engaging with the bottom of the adjustment assembly, the operator can store the cutter 66 in the storage component after use or after stripping the wire harness, preventing the cutter 66 from being exposed. This fundamentally eliminates the safety hazard of the operator being cut by the cutter 66 while cleaning the cutting cavity, ensuring the operator's personal safety and improving the safety of equipment use. The cutter 66 is rotatably mounted at one end of the adjustment assembly, with a second magnet 663 fixed to its top. A first magnet 654 is provided on the surface of the adjustment assembly, and the first magnet 654 is magnetically attracted to the second magnet 663. This magnetic design makes the installation and removal of the cutter 66 more convenient. The operator only needs to rotate it forward to store the cutter 66. During cutting, the cutter 66 rotates in the opposite direction, and the first magnet 654 limits the reverse rotation of the cutter 66, preventing it from shaking and further improving work efficiency.

[0022] In some embodiments, reference is made to Figure 1 , Figure 2 , Figure 6 , Figure 7 as well as Figure 8As shown, the reciprocating cutting assembly includes an upper pressure plate 2 and a lower pressure plate 3. Both ends of the upper pressure plate 2 are fixed with sliders 21. A groove 111 is provided on the inner side wall of the U-shaped plate 1. Both ends of the upper pressure plate 2 slide on the inner side wall of the groove 111 through the sliders 21. One end of the lower pressure plate 3 slides on the bottom wall of the U-shaped plate 1. The upper pressure plate 2 is located above the lower pressure plate 3. A top plate 12 is fixed on the top of the U-shaped plate 1. The top plate 12 is located above the upper pressure plate 2. A hydraulic rod 13 and multiple telescopic rods 131 are fixed between the top plate 12 and the upper pressure plate 2. The two ends of the hydraulic rod 13 and multiple telescopic rods 131 are fixedly connected to the bottom of the top plate 12 and the top of the upper pressure plate 2, respectively. The adjusting assembly is slidably arranged on the surface of the upper pressure plate 2. Multiple cutting components include arc-shaped groove 1 22 and arc-shaped groove 2 32. The multiple arc-shaped groove 1 22 and the multiple arc-shaped groove 2 32 are respectively opened at the bottom of the upper pressure plate 2 and the top of the lower pressure plate 3. The multiple arc-shaped groove 1 22 are located directly above the multiple arc-shaped groove 2 32. The multiple arc-shaped groove 1 22 and the multiple arc-shaped groove 2 32 are close to each other to form multiple rings. The aperture of the multiple rings is gradually decreasing from left to right. The inner walls of the multiple arc-shaped groove 1 22 and the multiple arc-shaped groove 2 32 are equipped with arc-shaped blades 33 for wire harness cutting and peeling. Multiple adjustment components include mounting plates 6 and limiting components for adjusting the cutting depth of the cutter 66. Multiple limiting components are located on the top of multiple mounting plates 6. One side of the mounting plate 6 is recessed to form a sliding groove 62. The inner wall of the sliding groove 62 is engraved with a limiting groove 621. A sliding plate 63 slides on the bottom wall of the sliding groove 62. The two ends of the sliding plate 63 slide on the inner side wall of the limiting groove 621. A push plate 64 is fixed on the top of the sliding plate 63. One end of the cutter 66 is rotatably disposed on the side of the push plate 64 near the lower pressure plate 3.

[0023] Specifically, during use, based on the outer diameter of the automotive wiring harness to be stripped, select the appropriate diameter annular position and place the wiring harness in the corresponding arc-shaped groove 32 on the lower pressure plate 3. At this time, activate the hydraulic rod 13. The hydraulic rod 13 extends and retracts, causing the upper pressure plate 2 to slide within the slide groove 111 via the slider 21. Simultaneously, multiple telescopic rods 131 also extend and retract, providing auxiliary support and stability, causing the upper pressure plate 2 to move closer to the lower pressure plate 3 until the arc-shaped groove 22 at the bottom of the upper pressure plate 2 mates with the arc-shaped groove 32 at the top of the lower pressure plate 3, clamping the wiring harness. At this point, the arc-shaped blade 3... 3. The wire harness is initially cut. The operator adjusts the cutting depth of the cutter 66 through the limiting component according to the insulation thickness and core diameter of the wire harness. At this time, the push plate 64 is pushed, and the push plate 64 drives the slide plate 63 to slide in the slide groove 62. The two ends of the slide plate 63 slide in the limiting groove 621 to guide and limit, so that the cutter 66 is pressed down to the appropriate position. Then the cutter 66 begins to further cut the wire harness to complete the removal of the insulation layer. After the cutting is completed, the hydraulic rod 13 retracts, driving the upper pressure plate 2 to rise, releasing the wire harness, and the operator can take out the wire harness. Furthermore, the apertures of the multiple rings are distributed in a gradually decreasing pattern from left to right, which can be adapted to various automotive wiring harnesses with different outer diameters. This eliminates the need for frequent replacement of cutting parts, improves the versatility and applicability of the equipment, and reduces production costs and operational difficulty.

[0024] In some embodiments, reference is made to Figure 1 , Figure 6 , Figure 7 as well as Figure 8 As shown, both sides of the mounting plate 6 are fixed with a clamping plate 61, one end of the limiting component engages with the inner side of the clamping plate 61, and the surfaces of both clamping plates 61 are engraved with scales 611 for detecting the moving distance of the cutter 66. The limiting assembly includes two side plates 641, which are fixed parallel to the top of the push plate 64. A cover plate 643 is rotatably mounted on the inner wall of each side plate 641 via a rotating column 642. A pull ring 645 is fixed to the top of each cover plate 643. A flexible arc-shaped locking block 644 is fixed to the side of each cover plate 643 away from the side plate 641. One end of each arc-shaped locking block 644 engages with the inner side of the two locking plates 61. The top of the push plate 64 is also provided with a buckle groove 65. When in use, the buckle groove 65 is held and pushed. A slot 651 is provided on the side of the push plate 64 near the cutter 66. The slot 651 is located at the bottom of the push plate 64, and a cavity 652 is formed at the bottom of the push plate 64. A fixing block 653 is fixed to the end of the push plate 64 near the cutter 66. A magnet 654 is fixed to the top of the fixing block 653. A rotating shaft 655 is rotatably mounted on the inner wall of the fixing block 653. One end of the cutter 66 is fixedly connected to the surface of the rotating shaft 655, and one end of the housing component is fixedly connected to the surface of the cutter 66. The storage assembly includes a connecting rod 661. One end of the connecting rod 661 is fixed to the outside of the cutter 66, and the other end of the connecting rod 661 is fixed to a connecting post 662. When the cutter 66 rotates about the pivot 655, the surface of the connecting post 662 engages with the inner wall of the slot 651. At this time, the cutter 66 is located in the cavity 652 and is in a stored state. Among them, the material of the arc-shaped card block 644 is preferably rubber, which has a certain degree of elasticity; Specifically, during use, when the operator needs to adjust the cutting depth of the cutter 66 according to the thickness of the wire harness insulation and the diameter of the wire core, first manually engage the latch 65 to move the push plate 64 down, and pull the pull ring 645 to rotate the cover plate 643 around the rotating column 642, so that the arc-shaped locking block 644 disengages from the inner side of the locking plate 61. Then push the push plate 64, which causes the slide plate 63 to slide in the slide groove 62. At the same time, observe the scale 611 on the surface of the locking plate 61 to accurately control the movement distance of the cutter 66, thereby adjusting the cutting depth to meet the stripping requirements of wire harnesses of different specifications, improving the quality and accuracy of wire harness stripping, and reducing wire harness damage and scrap caused by improper cutting depth. After adjustment, press the pull ring 645, and the arc-shaped locking block 644 re-engages with the inner side of the locking plate 61 to fix the position of the cutter 66. During the cutting process, the cutter 66 rotates in the opposite direction. Magnet 654 limits the reverse rotation of the cutter 66, preventing it from shaking and cutting the wire harness. After cutting, if the cutter 66 needs to be stored, the operator can hold the end of the connecting post 662 and push the cutter 66 to rotate around the pivot 655. The connecting rod 661 moves accordingly, driving the connecting post 662 into the slot 651 and engaging with the inner wall of the slot 651. At this time, the cutter 66 is located in the cavity 652, completing the storage and preventing the cutter 66 from being exposed. This effectively eliminates the safety hazard of the operator being cut by the cutter 66 while cleaning the cutting cavity or performing other operations, ensuring the operator's personal safety. At the same time, the engaging design of the connecting post 662 and the slot 651 ensures the stability of the cutter 66 in the stored state, preventing the cutter 66 from accidentally falling or shaking.

[0025] In some embodiments, reference is made to Figures 1 to 4 As shown, the bottom of the U-shaped plate 1 is fixed with multiple equally spaced support columns 11. A sliding groove 152 is provided on one side of the U-shaped plate 1. A moving block 34 is fixed at the bottom of the lower pressure plate 3. A pull ring 31 is fixed on the outer side of the lower pressure plate 3. The lower pressure plate 3 slides on the inner wall of the sliding groove 152 through the moving block 34. A blocking component for limiting the lower pressure plate 3 is also provided on one side of the U-shaped plate 1. The blocking assembly includes a rotating plate 15, which is located on one side of the moving block 34. A rotating rod 14 is rotatably mounted on the bottom of the U-shaped plate 1. One end of the rotating plate 15 is fixedly connected to the surface of the rotating rod 14. Two slots 141 are provided on one side of the U-shaped plate 1. Two rubber blocks 153 are fixed on the side of the rotating plate 15 near the U-shaped plate 1. The rotating plate 15 is engaged with the bottom wall of the two slots 141 by the two rubber blocks 153 respectively. A pull ring 151 is also fixed on the side of the rotating plate 15 away from the U-shaped plate 1. Specifically, when cleaning the bottom wall of the lower pressure plate 3 is required, the operator pulls the second pull ring 31, causing the moving block 34 at the bottom of the lower pressure plate 3 to slide within the second slide groove 152, thus moving the lower pressure plate 3 outward. Once the lower pressure plate 3 has moved to the appropriate position, the operator can use cleaning tools, such as a brush or rag, to clean the bottom wall of the lower pressure plate 3. Since the lower pressure plate 3 has been moved out, the operator can more easily access every corner of the bottom wall to clean up accumulated dust, debris, etc. After cleaning, the operator holds the second pull ring 31 again. Slowly push the lower pressure plate 3 back to its original position. During the reset process, align the moving block 34 with the slide groove 152 and push it in. At this time, the operator rotates the rotating plate 15 so that the rotating plate 15 rotates around the rotating rod 14 until the rubber block 153 on the rotating plate 15 is engaged with the bottom wall of the slot 141 on one side of the U-shaped plate 1. At this time, the rotating plate 15 blocks the movement path of the moving block 34, restricting the movement of the lower pressure plate 3 and preventing the lower pressure plate 3 from sliding accidentally during operation. This avoids accidental movement of the lower pressure plate 3 during operation and prevents injury to the operator, thus improving the safety of the equipment.

[0026] Furthermore, the movable lower pressure plate 3 design makes cleaning simpler and more efficient. Operators do not need to disassemble the entire device or complex components; simply pulling the pull ring 31 removes the lower pressure plate 3, quickly completing the cleaning process and saving significant time and effort. After the lower pressure plate 3 is removed, operators can thoroughly clean its bottom wall to ensure no residual dust or debris remains. This helps improve the performance and stability of the wire harness stripping machine, extends its service life, and also guarantees the quality of subsequent wire harness stripping.

[0027] In some embodiments, reference is made to Figure 1 , Figure 2 as well as Figure 5 As shown, a conveying assembly for conveying wire harnesses is also rotatably mounted on the inner wall of the U-shaped plate 1. The conveying assembly includes two conveying rollers 52, with a rotating shaft 51 fixed at both ends of each conveying roller 52. A gear 511 is fixed at one end of each rotating shaft 51, and the two gears 511 mesh with each other. One end of one rotating shaft 51 passes through the surface of the U-shaped plate 1 and is fixed with a drive motor 5. The drive motor 5 is fixed on the outside of the U-shaped plate 1. Multiple conveying ports 53 are formed between the two conveying rollers 52. The multiple conveying ports 53 are annular, and the inner diameter of the multiple conveying ports 53 is gradually decreasing from left to right. The multiple conveying ports 53 are respectively aligned with the annulus formed by multiple arc-shaped grooves 22 and multiple arc-shaped grooves 32. The inner wall of the multiple conveying ports 53 is provided with an anti-slip layer 54 to facilitate wire harness conveying. A fixing plate 4 is also fixed at the end of the U-shaped plate 1 away from the rotating plate 15. A plurality of guide grooves 41 are also provided on the side of the fixing plate 4 away from the rotating plate 15. The aperture of the plurality of guide grooves 41 is gradually decreasing from left to right. The plurality of guide grooves 41 are on the same vertical line as the plurality of annulus formed by the plurality of arc-shaped cut grooves 1 22 and the plurality of arc-shaped cut grooves 2 32. Specifically, during use, the drive motor 5 is started, which drives one of the rotating shafts 51 to rotate. Since the two gears 511 mesh with each other, the other rotating shaft 51 also rotates, thereby driving the two conveying rollers 52 to rotate synchronously, placing the automotive wiring harness into the guide groove 41 on the fixed plate 4. The tapered design of the guide groove 41 can initially guide and position wiring harnesses of different diameters, allowing the wiring harness to enter the conveying port 53 in the correct direction. The anti-slip layer 54 on the inner wall of the conveying port 53 increases the friction between the wiring harness and the conveying rollers 52, ensuring that the wiring harness can be stably conveyed as the conveying rollers 52 rotate. Since the conveying port 53 is directly opposite the ring formed by the arc-shaped cut groove 22 and the arc-shaped cut groove 32, the wiring harness will accurately enter the stripping area during the conveying process, preparing for the subsequent stripping operation.

[0028] Furthermore, the anti-slip layer 54 increases the friction between the wire harness and the conveying roller 52, effectively preventing the wire harness from slipping during the conveying process, ensuring that the wire harness can enter the stripping area stably and accurately, improving the reliability and accuracy of wire harness conveying, and providing a guarantee for subsequent stripping operations. Furthermore, the conveying port 53 is directly opposite the annulus formed by the arc-shaped cut 22 and the arc-shaped cut 32, and the guide groove 41 is on the same vertical line as the annulus, which enables the wire harness to accurately enter the stripping position.
