Description

Technical Field

[0001] This utility model relates to a wire harness cutting device, specifically a wire harness cutting device for automotive wiring harnesses, and belongs to the technical field of automotive wiring harness processing equipment. Background Technology

[0002] Automotive wiring harnesses are the core of a vehicle's electrical network; without them, there is no automotive electrical system. A wiring harness is an assembly consisting of copper-plated contact terminals crimped to electrical wires and cables, then covered with a plastic-molded insulator or an outer metal casing, and bundled together to form a circuit connection. During the manufacturing process of automotive wiring harnesses, certain steps require cutting them to different lengths to prepare for subsequent processing.

[0003] In the prior art, such as the automotive wiring harness length cutting equipment disclosed in announcement number CN215544540U, the equipment can solve the problems of low efficiency and high labor costs associated with manual cutting by using a limiting component fixed on the upper surface of the operating table. However, the above-mentioned prior art has the following shortcomings: When using this type of automotive wiring harness cutting equipment, the wiring harness needs to be manually straightened and clamped during the cutting process. Due to the different pulling force and speed during the pulling process, the internal wires may be stretched, deformed, or even broken, affecting the stability of the automotive electrical system. In addition, the labor cost is high and the production efficiency is low. Utility Model Content

[0004] The purpose of this invention is to provide a wire cutting device for automotive wiring harnesses, which addresses the problem that during the cutting process of the aforementioned wiring harnesses, the wiring harnesses need to be manually straightened and clamped. Due to the different pulling force and speed during the pulling process, the internal wires may be stretched, deformed, or even broken, affecting the stability of the automotive electrical system.

[0005] The present invention achieves the above objectives through the following technical solution: a wire cutting device for automotive wiring harnesses, comprising a worktable, a cutting mechanism mounted on the surface of the worktable, and a take-up roller mounted on the surface of the worktable.

[0006] A U-shaped frame is installed on the surface of the workbench. A cylinder is installed on the top and bottom of the U-shaped frame. A connecting plate is installed on the output shaft of the cylinder. A diagonal rod is installed on both ends of the connecting plate. Two sliders are set on the surface of the workbench. One end of the diagonal rod slides in the diagonal hole opened on the surface of the slider. A U-shaped seat is installed on the adjacent side of the two sliders. A clamping roller is rotatably connected inside the two U-shaped seats.

[0007] As a further embodiment of this utility model: a motor is mounted on the surface of one of the U-shaped seats, and the output shaft of the motor is connected to one end of the roller shaft of the clamping roller rotatably connected inside the U-shaped seat.

[0008] As a further embodiment of this utility model: a T-shaped rod is installed on one side of another U-shaped seat, one end of the T-shaped rod is slidably connected to a blind hole opened on one side surface of the slider, and a first spring is sleeved on the outer surface of the T-shaped rod, with the two ends of the first spring abutting against the slider and the U-shaped seat respectively.

[0009] As a further improvement of this utility model: the bottom surfaces of both sliders are equipped with U-shaped guide blocks, and the surface of the worktable is provided with guide grooves that match the guide blocks. The sliders are slidably connected to the surface of the worktable through the guide blocks and guide grooves.

[0010] As a further embodiment of this utility model: an L-shaped rod is installed on one side surface of each of the two sliders. One end of each L-shaped rod has a U-shaped structure, and a connecting rod is provided inside this end. A guide rod is slidably connected in the through hole opened on the surface of the L-shaped rod. The guide rod passes through one end of the L-shaped rod and is connected to the connecting rod. A second spring is sleeved on the surface of the guide rod. One end of the second spring abuts against one end of the connecting rod, and the other end of the second spring abuts against the L-shaped rod. An arc-shaped pad is installed on the other end of each connecting rod, and cleaning cotton is installed on the inner surface of the arc-shaped pad.

[0011] As a further improvement of this utility model: a guide sleeve is installed on the surface of the workbench, one end of the guide sleeve is flared and a sliding ball is installed on its inner surface.

[0012] As a further improvement of this utility model: a guide sleeve is installed on the surface of the workbench, and a through groove adapted to the cutting blade is opened on the surface of the guide sleeve.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes a clamping assembly, comprising a cylinder, connecting plate, inclined rod, slider, U-shaped seat, clamping roller, T-shaped rod, and first spring. The cylinder pushes the connecting plate downwards, causing the inclined rod to move. Since one end of the inclined rod slides within the inclined hole of the slider, the inclined rod's oblique thrust causes the two sliders to move towards each other. The slider then moves the U-shaped seat and its internal clamping roller closer to the wire harness, firmly clamping it. Starting the motor rotates the connected clamping roller, and under friction, the wire harness begins to be fed uniformly towards the cutting mechanism. This ensures uniform and stable clamping force on the wire harness during cutting, avoiding twisting and deformation caused by unstable clamping during manual wire feeding. The stable wire harness condition results in a smooth, flat cut surface free of burrs and tears, further improving the processing quality of the wire harness, reducing the risk of poor contact during subsequent wire harness installation, ensuring smooth transmission of automotive circuit signals, efficiently increasing production capacity, and reducing labor costs and intensity.

[0015] The T-shaped rod and the first spring work together to generate corresponding deformation according to the thickness of the wire harness, ensuring that the clamping roller applies appropriate pressure and avoids scratching, squeezing and other damage to the surface of the wire harness, thus effectively protecting product quality.

[0016] The cleaning structure, consisting of an L-shaped rod on one side of the two sliders, a second spring, and an arc-shaped pad with cleaning cotton, can clean the surface dust and impurities of the wire harness in real time before it is fed to the cutter. The clean wire harness surface makes the cut surface smoother and avoids problems such as uneven cutting lines and burrs caused by impurities. This significantly improves the cutting quality, reduces subsequent processing steps, lowers production costs, and also avoids damage to the cutting head during the cutting process.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] like Figures 1 to 6 As shown, a wire cutting device for automotive wiring harnesses includes a worktable 1, a cutting mechanism 2 mounted on the surface of the worktable 1, and a take-up roller 3 mounted on the surface of the worktable 1.

[0026] A U-shaped frame 4 is mounted on the surface of the workbench 1. A cylinder 5 is mounted on the top and bottom surfaces of the U-shaped frame 4. A connecting piece 6 is mounted on the output shaft of the cylinder 5. A diagonal rod 7 is mounted on both ends of the connecting piece 6. Two sliders 8 are provided on the surface of the workbench 1. One end of the diagonal rod 7 slides in the diagonal hole opened on the surface of the slider 8. A U-shaped seat 9 is mounted on the adjacent side of the two sliders 8. A clamping roller 10 is rotatably connected inside the two U-shaped seats 9.

[0027] When it is necessary to cut the automotive wiring harness, the cylinder 5 installed on the top and bottom surface of the U-shaped frame 4 is activated. The output shaft of the cylinder 5 pushes the connecting piece 6 downward, and the connecting piece 6 drives the inclined rod 7 to move. Since one end of the inclined rod 7 slides in the inclined hole of the slider 8, the inclined thrust of the inclined rod 7 will cause the two sliders 8 to move towards each other. The slider 8 drives the U-shaped seat 9 and its internal clamping roller 10 to approach the wiring harness and clamp the wiring harness firmly. Thus, the wiring harness can be clamped and fixed when cutting, avoiding displacement of the wiring harness during the cutting process and causing misalignment of the cut, thereby improving the cutting efficiency.

[0028] Furthermore, a motor 23 is mounted on the surface of one of the U-shaped seats 9, and the output shaft of the motor 23 is connected to one end of the clamping roller 10 rotatably connected inside the U-shaped seat 9.

[0029] At this point, the motor 23 mounted on the surface of one of the U-shaped seats 9 comes into play. The motor 23 starts, driving the connected clamping roller 10 to rotate. Under the action of friction, the wire harness begins to be fed uniformly towards the cutting mechanism 2. This ensures that the clamping force on the wire harness is uniform and stable during cutting, avoiding the twisting and deformation of the wire harness caused by unstable clamping during manual wire feeding. The stable wire harness condition results in a smooth and flat cut surface, free of burrs, tears, and other defects, further improving the processing quality of the wire harness, reducing the risk of poor contact during subsequent wire harness installation, ensuring smooth transmission of automotive circuit signals, efficiently increasing production capacity, and reducing labor costs and labor intensity.

[0030] Furthermore, a T-shaped rod 11 is installed on one side of another U-shaped seat 9. One end of the T-shaped rod 11 is slidably connected to a blind hole opened on one side surface of the slider 8. A first spring 12 is sleeved on the outer surface of the T-shaped rod 11. The two ends of the first spring 12 abut against the slider 8 and the U-shaped seat 9 respectively.

[0031] The T-shaped rod 11 on one side of the other U-shaped seat 9 slides in the blind hole of the slider 8. The first spring 12 outside the T-shaped rod 11 is compressed. The elastic force of the first spring 12 plays a buffering role, ensuring that the two clamping rollers 10 can provide appropriate clamping force for wire harnesses of different thicknesses, and avoid damage to the wire harnesses.

[0032] Furthermore, the bottom surfaces of both sliders 8 are equipped with U-shaped guide blocks 13, and the surface of the worktable 1 is provided with guide grooves 14 that match the guide blocks 13. The sliders 8 are slidably connected to the surface of the worktable 1 through the guide blocks 13 and the guide grooves 14.

[0033] To ensure the stability of the slider 8 sliding on the surface of the worktable 1, a guide block 13 is installed on the bottom surface of the slider 8, and a guide groove 14 matching the guide block 13 is opened on the surface of the worktable 1. Example 2

[0034] Improvements based on Example 1:

[0035] like Figures 1 to 6 As shown, L-shaped rods 18 are installed on one side surface of both sliders 8. One end of each L-shaped rod 18 has a U-shaped structure, and a connecting rod 21 is provided inside this end. A guide rod 19 is slidably connected in the through hole opened on the surface of the L-shaped rod 18. The guide rod 19 passes through one end of the L-shaped rod 18 and is connected to the connecting rod 21. A second spring 20 is sleeved on the surface of the guide rod 19. One end of the second spring 20 abuts against one end of the connecting rod 21, and the other end of the second spring 20 abuts against the L-shaped rod 18. An arc-shaped pad 22 is installed on the other end of the connecting rod 21. Cleaning cotton is installed on the inner surface of the arc-shaped pad 22.

[0036] During the cutting process, the L-shaped rod 18 structure on one side of the two sliders 8 also begins to function. The connecting rod 21, which is slidably connected within the U-shaped structure at one end of the L-shaped rod 18, is guided by the guide rod 19 and the second spring 20, causing the arc-shaped pad 22 at the other end of the connecting rod 21 to fit tightly against the surface of the wire harness. The cleaning cotton on the inner surface of the arc-shaped pad 22 can clean dust and impurities from the surface of the wire harness in real time, ensuring a clean and tidy cutting surface, improving the cutting quality, and preventing debris on the surface of the wire harness from damaging the cutting head during the cutting process.

[0037] Furthermore, a guide sleeve 16 is installed on the surface of the workbench 1. One end of the guide sleeve 16 is flared and a ball bearing 17 is installed on its inner surface.

[0038] As the wire harness is fed, it passes through the guide sleeve 16 installed on the surface of the workbench 1. One end of the guide sleeve 16 is designed in the shape of a flared mouth, and a sliding ball 17 is installed on the inner surface. The flared mouth facilitates the smooth entry of the wire harness into the guide sleeve 16, while the sliding ball 17 reduces the friction between the wire harness and the inner wall of the guide sleeve 16, making the wire harness feeding smoother.

[0039] Furthermore, a guide sleeve 15 is installed on the surface of the workbench 1, and a through groove adapted to the cutting blade is opened on the surface of the guide sleeve 15.

[0040] The guide sleeve 15 on the surface of the worktable 1 also plays a further guiding role for the wire harness, ensuring that the wire harness accurately reaches the cutting position.

[0041] It should be noted that the guide sleeve 15 is designed in segments to facilitate the cutting of the wire harness. After cutting, the wire harness needs to be manually pulled out so that it can be cut again.

[0042] Working principle: When it is necessary to cut the automotive wiring harness, the cylinder 5 installed on the top and bottom surface of the U-shaped frame 4 is activated. The output shaft of the cylinder 5 pushes the connecting piece 6 downward, and the connecting piece 6 drives the inclined rod 7 to move. Since one end of the inclined rod 7 slides in the inclined hole of the slider 8, the inclined thrust of the inclined rod 7 will cause the two sliders 8 to move towards each other. The slider 8 drives the U-shaped seat 9 and its internal clamping roller 10 to approach the wiring harness and clamp the wiring harness firmly. At this time, the motor 23 installed on the surface of one of the U-shaped seats 9 plays a role. The motor 23 starts and drives the clamping roller 10 connected to it to rotate. Under the action of friction, the wiring harness begins to be conveyed at a constant speed towards the cutting mechanism 2. Thus, the wiring harness can be clamped and fixed when cutting the wiring harness, avoiding displacement of the wiring harness during the cutting process and causing misalignment of the cut, thereby improving the cutting efficiency.

[0043] The T-shaped rod 11 on one side of the other U-shaped seat 9 slides in the blind hole of the slider 8. The first spring 12 outside the T-shaped rod 11 is compressed. The elastic force of the first spring 12 plays a buffering role, ensuring that the two clamping rollers 10 can provide appropriate clamping force for wire harnesses of different thicknesses, and avoid damage to the wire harness.

[0044] To ensure the stability of the slider 8 sliding on the surface of the worktable 1, a guide block 13 is installed on the bottom surface of the slider 8, and a guide groove 14 matching the guide block 13 is opened on the surface of the worktable 1.

[0045] During the cutting process, the L-shaped rod 18 structure on one side of the two sliders 8 also begins to function. The connecting rod 21, which is slidably connected within the U-shaped structure at one end of the L-shaped rod 18, is guided by the guide rod 19 and the second spring 20, causing the arc-shaped pad 22 at the other end of the connecting rod 21 to fit tightly against the surface of the wire harness. The cleaning cotton on the inner surface of the arc-shaped pad 22 can clean dust and impurities from the surface of the wire harness in real time, ensuring a clean and tidy cutting surface, improving the cutting quality, and preventing debris on the surface of the wire harness from damaging the cutting head during the cutting process.

[0046] As the wire harness is fed, it passes through the guide sleeve 16 installed on the surface of the workbench 1. One end of the guide sleeve 16 is designed in the shape of a flared mouth, and a sliding ball 17 is installed on the inner surface. The flared mouth facilitates the smooth entry of the wire harness into the guide sleeve 16, while the sliding ball 17 reduces the friction between the wire harness and the inner wall of the guide sleeve 16, making the wire harness feeding smoother.
