Technical Field

[0001] This invention relates to the field of wire harness cutting technology, specifically a wire harness cutting machine. Background Technology

[0002] In the current wire harness processing field, wire harness cutting and stripping are two key and common processes.

[0003] In traditional cutting machines, the peeling depth is typically adjusted by changing the blades of different specifications or adjusting their positions.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1 In one embodiment, such as Figures 1-6 As shown, a wire harness cutting machine includes a base 1 and a vertical plate 2 fixed on the base 1. A top plate 23 is fixed to the upper end of the vertical plate 2. A cylinder 3 is installed on the upper end of the top plate 23. The telescopic end of the cylinder 3 extends to the lower end of the top plate 23 and is fixedly connected to a movable plate 31. A second cutting blade 32 is fixed in the middle of the lower end of the movable plate 31. A first cutting blade 12 is arranged directly below the second cutting blade 32. The first cutting blade 12 is fixedly installed in the middle of the upper end of a chip collection frame 11. The chip collection frame 11 is fixedly installed on the upper end of the base 1. The front end of the vertical plate 2 is provided with two fixing members 4 for fixing the wire harness and two ring-cutting structures 7 for stripping the wire harness ends, respectively. The two ring-cutting structures 7 are located between the two fixing members 4. The cutting blade 32 is located between the two ring-cutting structures 7. An adjusting member 6 for adjusting the stripping depth of the wire harness by the ring-cutting structure 7 is provided between each fixing member 4 and each ring-cutting structure 7. The rear end of the vertical plate 2 is provided with an adjusting structure 5 for adjusting the fixing members 4 and the adjusting member 6.

[0026] In this embodiment, the wire harness to be processed is first placed at a suitable position at the front end of the vertical plate 2. The wire harness is then firmly fixed by two fasteners 4 through the adjustment structure 5 at the rear end of the vertical plate 2, ensuring that the wire harness will not move randomly during subsequent operations. In conjunction with the adjustment piece 6 between each fastener 4 and the corresponding ring-cutting structure 7, the stripping depth of the wire harness by the ring-cutting structure 7 is precisely adjusted.

[0027] When the cylinder 3 installed on the top plate 23 is activated, its telescopic end pushes the movable plate 31 downward. The second cutting blade 32 at the lower center of the movable plate 31 then moves downward, cooperating with the first cutting blade 12 fixed at the upper center of the chip collection frame 11 to cut the wire harness between them to the required length. The debris generated during the cutting process falls into the chip collection frame 11 below, facilitating subsequent centralized cleaning and maintaining a clean working environment.

[0028] Example 2 Based on Embodiment 1, the fixing member 4 includes a fixing plate 41 fixed to the front end of the vertical plate 2. A toothed ring 42 is rotatably mounted on the fixing plate 41. The toothed ring 42 is connected to the adjustment structure 5. A central hole 411 is opened on the fixing plate 41. The central hole 411 and the toothed ring 42 are arranged concentrically. The toothed ring 42 is rotatably connected to one end of a plurality of connecting strips 43. The plurality of connecting strips 43 are circumferentially distributed on the toothed ring 42. The other end of the connecting strips 43 is rotatably connected to a pressure block 44. The other end of the pressure block 44 is rotatably connected to the fixing plate 41. A roller 45 is rotatably mounted on one end of the pressure block 44 near the center of the central hole 411.

[0029] It should be noted that the adjusting structure 5 drives the toothed ring 42 to rotate, and the rotation of the toothed ring 42 causes the connecting strip 43 connected to it to move. The connecting strip 43 drives the pressure block 44 to rotate around the rotation point of the fixed plate 41. The roller 45 on the pressure block 44 moves closer to the center of the central hole 411, thereby pressing and fixing the wire harness passing through the central hole 411. When it is necessary to loosen the wire harness, the adjusting structure 5 drives the toothed ring 42 to rotate in the opposite direction, and all components move in the opposite direction. The roller 45 moves away from the center of the central hole 411, and the wire harness can be taken out.

[0030] Example 3 Based on Embodiments 1 and 2, the adjustment structure 5 includes a motor 51 and two gears 52 installed at the rear end of the vertical plate 2. Two through-holes 22 are symmetrically opened at the rear end of the vertical plate 2. Each gear 52 passes through the corresponding through-hole 22 and meshes with the corresponding gear ring 42. The output end of the motor 51 is fixedly connected to one gear 52. A bidirectional lead screw 53 is coaxially fixed between the two gears 52. The bidirectional lead screw 53 is rotatably installed between two fixed blocks 221. A guide rod 54 is fixed between the two fixed blocks 221. The two ends of the bidirectional lead screw 53 are threadedly connected to two moving blocks 55 respectively. The two moving blocks 55 slide with the guide rod 54, and the moving blocks 55 are connected to the adjustment component 6.

[0031] It should be noted that when the adjusting structure 5 is working, the motor 51 starts, and its output drives one gear 52 to rotate. Since the two gears 52 are coaxially connected through the bidirectional lead screw 53, the other gear 52 also rotates. When the bidirectional lead screw 53 rotates, the two moving blocks 55 move in opposite directions or away from each other along the bidirectional lead screw 53 under the guidance of the guide rod 54. The movement of the moving blocks 55 drives the toothed ring 42 in the fixing member 4 to rotate through the adjusting member 6. The rotation of the toothed ring 42 then drives the connecting strip 43 and the pressure block 44 to move, thereby realizing the fixing or loosening operation of the wire harness by the fixing member 4. At the same time, it can also play a linkage role with the adjusting member 6 to adjust the stripping depth of the ring-cutting structure 7.

[0032] Example 4 Based on Embodiments 1, 2, and 3, the vertical plate 2 has two through-holes 24 symmetrically opened at its rear end. The adjusting member 6 includes two connecting blocks 61 that slide inside the two through-holes 24. One end of the connecting block 61 is fixedly connected to the moving block 55, and the other end of the connecting block 61 is fixedly connected to the adjusting plate 62. An adjusting ring 63 is rotatably installed in the middle of the adjusting plate 62. Several inserts 64 are fixed at one end of the adjusting ring 63 near the ring-cut structure 7. The inserts 64 are equidistantly distributed on the adjusting ring 63.

[0033] It should be noted that the movement of the moving block 55 causes the connecting block 61 to slide within the through-hole 24. The connecting block 61 then moves the adjusting plate 62, and the adjusting ring 63 on the adjusting plate 62 can be manually rotated. When the adjusting ring 63 rotates, the insert block 64 on it interacts with the corresponding structure on the ring-cutting structure 7, causing the ring-cutting structure 7 to adjust its position, thereby adjusting the stripping depth of the ring-cutting structure 7. This design makes the adjustment of the stripping depth more flexible and precise, allowing for detailed operation according to the needs of different wire harnesses.

[0034] Example 5 Based on Embodiments 1, 2, 3, and 4, the ring-cutting structure 7 includes a ring-cutting plate 71 fixed to the front end of the vertical plate 2. A gear 72 is rotatably mounted in the middle of the ring-cutting plate 71. A plurality of insertion slots 721 are provided through the gear 72. Each insertion slot 721 cooperates with a plug block 64. A central opening 722 is provided through the middle of the gear 72. A channel 723 is provided between each insertion slot 721 and the central opening 722. A ring-cutting component 73 is slidably installed inside each channel 723.

[0035] The gear 72 meshes with the rack 33, the rack 33 is fixed to the lower end of the movable plate 31, the rear end of the rack 33 is fixed with a guide block 331, and the front end of the vertical plate 2 is provided with a guide groove 21 that cooperates with the guide block 331.

[0036] The ring-cutting component 73 includes a ring-cutting rod 731 slidably installed inside the channel 723. One end of the ring-cutting rod 731 extends into the center opening 722 and is fixedly connected to a limiting plate 732. One end of the limiting plate 732 near the ring-cutting rod 731 is fixedly connected to one end of a spring 734. The other end of the spring 734 is fixedly connected to the inner wall of the center opening 722. The other end of the limiting plate 732 is fixedly equipped with a ring-cutting blade 733. The other end of the ring-cutting rod 731 extends into the insertion port 721 and is rotatably mounted with a roller 735. The roller 735 contacts the insertion block 64.

[0037] The end of the insert 64 near the roller 735 is set as an inclined surface.

[0038] It should be noted that when the peeling depth needs to be adjusted, the position of the insert block 64 is changed by adjusting structure 5. Since the end of the insert block 64 near the roller 735 is inclined, as the insert block 64 moves, its inclined surface exerts a force on the roller 735, pushing the ring-cutting rod 731 to slide within the channel 723. The ring-cutting rod 731 drives the limiting plate 732 to move, and the ring-cutting blade 733 on the limiting plate 732 moves closer to or further away from the wire harness in the center opening 722. The spring 734 acts as a buffer and reset mechanism, ensuring a smooth and precise adjustment process, ultimately achieving the adjustment of the peeling depth.

[0039] During the cutting process, the movable plate 31 moves downward under the action of a cylinder or other driving device, and the rack 33 fixed to the lower end of the movable plate 31 moves downward accordingly. Since the rack 33 is meshed with gear 72, the movement of the rack 33 drives gear 72 to rotate. When gear 72 rotates, the ring cutter 73 moves in a circular motion around the wire harness, and the ring cutter 733 cuts the outer sheath of the wire harness, completing the stripping operation at the end or tail of the wire harness. The cooperation between the guide block 331 and the guide groove 21 provides precise guidance for the movement of the rack 33, ensuring the accuracy and stability of the ring cutting action.

[0040] In an optional embodiment, the chip collection frame 11 has openings 13 on both sides of its upper end, and a chip collection drawer 14 slides inside the chip collection frame 11.

[0041] It should be noted that during the operation of the equipment, such as wire harness cutting and stripping, a large amount of debris is generated. This debris, under its own weight, falls smoothly into the debris collection frame 11 through the drain 13, preventing it from scattering and maintaining a clean working environment. Once a certain amount of debris has been collected in the debris collection drawer 14, the operator can simply pull the drawer 14 out of the debris collection frame 11 for convenient and quick centralized disposal of the debris, eliminating the need to clean the entire debris collection frame 11, thus greatly improving cleaning efficiency.

[0042] The above embodiment discloses a wire harness cutting machine, wherein, through the adjustment structure at the rear end of the vertical plate, the motor 51 starts and drives the gear 52 to rotate, the bidirectional lead screw 53 rotates accordingly, and the two moving blocks 55 move towards or away from each other under the guidance of the guide rod 54. The moving blocks 55 drive the connecting block 61 to slide within the through-hole 24, thereby causing the adjusting ring 63 on the adjusting plate 62 to move. At the same time, the adjusting ring 63 can be manually rotated, and the inclined insert 64 on it cooperates with the insert 721 of the gear 72 in the ring cutting structure 7, pushing the ring cutting rod 731 to slide within the channel 723. The spring 734 drives the ring cutting blade 733 to move closer to or away from the wire harness, thereby adjusting the stripping depth. Simultaneously, the movement of the moving blocks 55 also drives the toothed ring 42 in the fixing member 4 to rotate, causing the roller 45 on the pressure block 44 to press or release the wire harness passing through the central hole 411.

[0043] When the cylinder 3 on the top plate 23 is activated, the telescopic end pushes the movable plate 31 downward. The rack 33 fixed at the lower end of the movable plate 31 moves downward accordingly. The guide block 331 cooperates with the guide groove 21 to ensure precise movement. The rack 33 meshes with the gear 72 to drive its rotation. The ring cutter 73 moves in a circular motion around the wire harness. The ring cutter 733 cuts the outer skin of the wire harness end or end to achieve peeling. At the same time, the cutting blade 32 at the lower middle of the movable plate 31 moves downward and cooperates with the cutting blade 12 fixed at the upper end of the chip collection frame 11 to cut the wire harness to the required length.

[0044] The debris generated during the cutting and peeling process falls into the chip collection frame 11 through the openings 13 on both sides of the upper end of the chip collection frame 11 under its own gravity. When the debris in the chip collection drawer 14 accumulates to a certain extent, the operator can pull the chip collection drawer 14 out of the chip collection frame 11 for centralized processing.

[0045] Any aspects of this invention not described in detail are well-known to those skilled in the art.

[0046] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
