Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness production technology, and more specifically, to a wiring harness cutting device for automotive wiring harness production. Background Technology

[0002] Automotive wiring harnesses are the main network of automotive circuits, responsible for transmitting and distributing electrical energy, and connecting various electronic components. In automobiles, wiring harnesses are an indispensable part, and their performance directly affects the vehicle's operating condition and safety performance.

[0003] Existing wire harness cutting devices used in automotive wire harness production do not have a buffer component for the cutting head. During long-term cutting operations, the downward pressure can easily damage the cutting head, making it unable to cut, thus shortening the cutting head's service life and increasing subsequent maintenance costs.

[0004] A search revealed that Chinese Patent CN222607871U discloses a wire harness cutting device for automotive wire harness production. This structure, through a buffer mechanism design, achieves a buffering function for the cutting head, solving the problem that existing cutting devices do not have a buffer component for the cutting head. During long-term cutting processing, the downward pressure can easily damage the cutting head, making it unable to cut, thus shortening the cutting head's service life and increasing subsequent maintenance costs. This improves the protection of the cutting head and also achieves an automatic adjustment function for the cutting position. This solves the problem that existing cutting devices do not have a component for adjusting the position of the wire harness. When cutting the wire harness, the cutting position needs to be manually adjusted, but manual adjustment is prone to errors, resulting in inaccurate cutting positions. This improves the accuracy.

[0005] However, in actual use, the specifications and materials of automotive wiring harnesses may vary, and the fixing device cannot adaptively adjust according to the different characteristics of the wiring harnesses. This makes it difficult to ensure stable fixing of various wiring harnesses, resulting in large errors caused by changes in the position of the wiring harness during cutting, which affects cutting accuracy and product quality. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wire harness cutting device for automotive wire harness production, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A wire harness cutting device for automotive wire harness production includes a base plate, a first fixing frame and a second fixing frame are fixedly disposed on the top of the base plate, the first fixing frame is disposed on one side of the second fixing frame, a U-shaped fixing frame is disposed between the first fixing frame and the second fixing frame, and a positioning mechanism is disposed inside the base plate.

[0009] The positioning mechanism includes an electric telescopic rod fixedly mounted on the top of the first fixed frame. An upper positioning plate is fixedly mounted on the output end of the electric telescopic rod. Slider blocks are fixedly mounted on both sides of the upper positioning plate. A sliding groove is opened on the surface of the first fixed frame, and the slider is slidably connected to the sliding groove.

[0010] A lower positioning plate is fixedly installed on the inner wall of the base plate. A rubber layer is fixedly installed on the surface of both the upper and lower positioning plates. Multiple fixing grooves are opened on the surface of the base plate, and movable blocks are slidably installed inside the fixing grooves.

[0011] A stepper motor is fixedly installed on the surface of the base plate. A threaded rod is fixedly provided at the output end of the stepper motor. One of the movable blocks is threadedly connected to the threaded rod. A guide rod is fixedly provided inside the fixed groove. The other movable block is slidably connected to the guide rod.

[0012] By adopting the above technical solution, the wire harness can be quickly and firmly fixed to prevent displacement during cutting. Moreover, the cutting length of the wire harness can be precisely adjusted, effectively reducing errors and ensuring the stability and accuracy of the movement of each component.

[0013] As a further description of the above technical solution: an auxiliary mechanism is provided on one side of the second fixed frame. The auxiliary mechanism includes a plurality of second electric telescopic rods fixedly installed on the top of the second fixed frame. A movable frame is fixedly installed at the output end of the second electric telescopic rod. Rollers are rotatably installed on the inner walls of both the second fixed frame and the movable frame.

[0014] An electric push rod is fixedly installed on the top of the U-shaped fixed frame. A stabilizing plate is fixedly installed at the output end of the electric push rod, and a cutting blade is inserted into the inside of the stabilizing plate.

[0015] By adopting the above technical solution, the contact pressure with the wire harness can be flexibly adjusted to ensure that the wire harness is fed at a uniform speed and stably during the cutting process, avoiding jamming or deviation, and ensuring that the cutting blade makes precise vertical cuts, thus improving the cut quality.

[0016] As a further description of the above technical solution: guide blocks are fixedly provided on both sides of the stabilizing plate, a guide groove is provided on the surface of the U-shaped fixing frame, the guide block is slidably connected to the guide groove, and threaded grooves are provided on the surfaces of the stabilizing plate and the cutting blade, and bolts are threadedly connected inside the threaded grooves.

[0017] By adopting the above technical solution, the stabilizing plate and the cutting blade are connected by threaded grooves and bolts, enabling quick disassembly and replacement of the blade. Maintenance operations can be completed without complicated tools, significantly reducing downtime and improving equipment utilization.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] By setting up a positioning mechanism, compared with existing technologies, the initial fixing of the wire harness is achieved through an electric telescopic rod, an upper positioning plate, and a lower positioning plate in conjunction with a rubber layer. This has significant advantages. The electric telescopic rod precisely controls the downward movement of the upper positioning plate, and the sliding cooperation between the slider and the groove ensures vertical movement, avoiding deviation that affects the fixing effect. The rubber layer increases the friction between the wire harness and the wire harness, which can firmly fix wire harnesses of different specifications, prevent shaking and displacement during cutting, and ensure cutting accuracy. This design keeps the wire harness stable during subsequent precise length adjustment, auxiliary conveying, and cutting operations, reduces cutting errors caused by changes in wire harness position, improves production efficiency and product quality, and at the same time, the structure is simple, easy to operate and maintain, and reduces manual intervention and production costs.

[0020] By incorporating auxiliary mechanisms, this technology achieves highly efficient and precise wire harness cutting compared to existing technologies. A stepper motor drives a threaded rod to rotate, which, in conjunction with a movable block and guide rod, allows for precise adjustment of the wire harness cutting length according to production needs. This effectively avoids errors from manual measurement and improves cutting dimensional accuracy. Furthermore, a second electric telescopic rod drives a roller to contact the wire harness, and the roller's rotation assists in conveying the wire harness, ensuring a uniform and stable cutting speed and preventing uneven cuts caused by wire harness vibration. An electric push rod drives a stabilizing plate to move vertically downwards, and the guide block and guide groove work together to ensure vertical cutting by the cutting blade. The threaded groove and bolt design facilitates quick tool replacement. The entire process significantly improves production efficiency and cutting quality, reduces scrap rates, and enhances enterprise production benefits. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] The embodiments disclosed in this application are as follows: Figure 1-5 The diagram shows a wire harness cutting device for automotive wire harness production, including a base plate 1. A first fixing frame 2 and a second fixing frame 3 are fixedly arranged on the top of the base plate 1. The first fixing frame 2 is arranged on one side of the second fixing frame 3. A U-shaped fixing frame 4 is arranged between the first fixing frame 2 and the second fixing frame 3. A positioning mechanism is arranged inside the base plate 1.

[0029] The positioning mechanism includes an electric telescopic rod 5 fixedly installed on the top of the first fixed frame 2. An upper positioning plate 6 is fixedly installed at the output end of the electric telescopic rod 5. Slider 7 is fixedly installed on both sides of the upper positioning plate 6. A sliding groove is opened on the surface of the first fixed frame 2, and the slider 7 is slidably connected to the sliding groove.

[0030] A lower positioning plate 8 is fixedly installed on the inner wall of the base plate 1. A rubber layer 9 is fixedly installed on the surface of both the upper positioning plate 6 and the lower positioning plate 8. Multiple fixing grooves are opened on the surface of the base plate 1, and movable blocks 10 are slidably installed inside the fixing grooves.

[0031] A stepper motor is fixedly installed on the surface of the base plate 1. A threaded rod 11 is fixedly provided at the output end of the stepper motor. One of the movable blocks 10 is threadedly connected to the threaded rod 11. A guide rod 12 is fixedly provided inside the fixed groove. The other movable block 10 is slidably connected to the guide rod 12.

[0032] The car wiring harness to be cut is placed between the first fixed frame 2 and the second fixed frame 3, passing through the internal space of the U-shaped fixed frame 4, so that the wiring harness is within the working area of ​​the entire cutting device.

[0033] Then, the electric telescopic rod 5, the stepper motor, the second electric telescopic rod 13 and the electric push rod 16 are all connected to an external power source. The electric telescopic rod 5, which is fixedly set at the top of the first fixed frame 2, is started. The output end of the electric telescopic rod 5 drives the upper positioning plate 6 to move downward. The sliders 7 on both sides of the upper positioning plate 6 slide in the grooves on the surface of the first fixed frame 2 to ensure that the upper positioning plate 6 moves vertically downward.

[0034] When the upper positioning plate 6 and the lower positioning plate 8 come into contact with the wire harness, since the upper positioning plate 6 and the lower positioning plate 8 are both fixedly provided with rubber layers 9, the rubber layers 9 increase the friction between the wire harness and the wire harness, thereby initially fixing the wire harness in a suitable position and preventing the wire harness from moving in subsequent operations.

[0035] Next, the stepper motor fixedly mounted on the surface of the base plate 1 is started. The output end of the stepper motor drives the threaded rod 11 to rotate. One of the movable blocks 10, which is threadedly connected to the threaded rod 11, will move along the fixed groove on the surface of the base plate 1 under the rotation of the threaded rod 11. The other movable block 10, which is slidably connected to the guide rod 12, plays a guiding role, ensuring that the two movable blocks 10 move synchronously, thereby accurately adjusting the length of the wire harness to be cut.

[0036] Reference Figure 2-3 As shown, an auxiliary mechanism is provided on one side of the second fixed frame 3. The auxiliary mechanism includes a plurality of second electric telescopic rods 13 fixedly installed on the top of the second fixed frame 3. A movable frame 14 is fixedly installed at the output end of the second electric telescopic rod 13. Rollers 15 are rotatably installed on the inner walls of both the second fixed frame 3 and the movable frame 14.

[0037] An electric push rod 16 is fixedly installed on the top of the U-shaped fixed frame 4. A stabilizing plate 17 is fixedly installed at the output end of the electric push rod 16. A cutting blade 18 is inserted into the inside of the stabilizing plate 17.

[0038] Start the stepper motor fixedly installed on the surface of the base plate 1. The output end of the stepper motor drives the threaded rod 11 to rotate. One of the movable blocks 10, which is threadedly connected to the threaded rod 11, will move along the fixed groove on the surface of the base plate 1 under the rotation of the threaded rod 11. The other movable block 10, which is slidably connected to the guide rod 12, plays a guiding role to ensure that the two movable blocks 10 move synchronously, thereby accurately adjusting the length of the wire harness to be cut.

[0039] Then, the multiple second electric telescopic rods 13 fixedly installed at the top of the second fixed frame 3 are activated. The output end of the second electric telescopic rod 13 drives the movable frame 14 to move downward, so that the rollers 15 on the inner wall of the second fixed frame 3 and the movable frame 14 come into contact with the wire harness. The rollers 15 rotate, which plays an auxiliary role in conveying and guiding the wire harness, so that the wire harness maintains a stable conveying state during the cutting process.

[0040] Reference Figure 4-5As shown, guide blocks 19 are fixedly installed on both sides of the stabilizing plate 17, and guide grooves are opened on the surface of the U-shaped fixing frame 4. The guide blocks 19 are slidably connected to the guide grooves. Threaded grooves are opened on the surfaces of the stabilizing plate 17 and the cutting blade 18, and bolts 20 are threadedly connected inside the threaded grooves.

[0041] As the stabilizing plate 17 moves downward, the cutting blade 18 fixed inside it moves downward accordingly to cut the wire harness of the pre-positioned length. Since both the stabilizing plate 17 and the cutting blade 18 have threaded grooves on their surfaces, they are connected by bolts 20, which allows for easy disassembly and replacement of the cutting blade 18.

[0042] Working principle of this utility model:

[0043] This utility model is a wire harness cutting device for automotive wire harness production. When using the device, the automotive wire harness to be cut is placed between the first fixed frame 2 and the second fixed frame 3, passing through the internal space of the U-shaped fixed frame 4, so that the wire harness is within the working area of ​​the entire cutting device.

[0044] Then, the electric telescopic rod 5, the stepper motor, the second electric telescopic rod 13 and the electric push rod 16 are all connected to an external power source. The electric telescopic rod 5, which is fixedly set at the top of the first fixed frame 2, is started. The output end of the electric telescopic rod 5 drives the upper positioning plate 6 to move downward. The sliders 7 on both sides of the upper positioning plate 6 slide in the grooves on the surface of the first fixed frame 2 to ensure that the upper positioning plate 6 moves vertically downward.

[0045] When the upper positioning plate 6 and the lower positioning plate 8 come into contact with the wire harness, since the upper positioning plate 6 and the lower positioning plate 8 are both fixedly provided with rubber layers 9, the rubber layers 9 increase the friction between the wire harness and the wire harness, thereby initially fixing the wire harness in a suitable position and preventing the wire harness from moving in subsequent operations.

[0046] Next, the stepper motor fixedly installed on the surface of the base plate 1 is started. The output end of the stepper motor drives the threaded rod 11 to rotate. One of the movable blocks 10, which is threadedly connected to the threaded rod 11, will move along the fixed groove on the surface of the base plate 1 under the rotation of the threaded rod 11. The other movable block 10, which is slidably connected to the guide rod 12, plays a guiding role, ensuring that the two movable blocks 10 move synchronously, thereby accurately adjusting the length of the wire harness to be cut.

[0047] Then, the multiple second electric telescopic rods 13 fixedly set at the top of the second fixed frame 3 are activated. The output end of the second electric telescopic rod 13 drives the movable frame 14 to move downward, so that the rollers 15 on the inner wall of the second fixed frame 3 and the movable frame 14 come into contact with the wire harness. The rollers 15 rotate, which plays an auxiliary role in conveying and guiding the wire harness, so that the wire harness maintains a stable conveying state during the cutting process.

[0048] Next, the electric push rod 16 fixedly installed on the top of the U-shaped fixed frame 4 is activated. The output end of the electric push rod 16 drives the stabilizing plate 17 to move downward. The guide blocks 19 on both sides of the stabilizing plate 17 slide in the guide groove on the surface of the U-shaped fixed frame 4 to ensure that the stabilizing plate 17 moves vertically downward.

[0049] As the stabilizing plate 17 moves downward, the cutting blade 18 fixed inside it moves downward accordingly to cut the wire harness of the pre-positioned length. Since both the stabilizing plate 17 and the cutting blade 18 have threaded grooves on their surfaces, they are connected by bolts 20, which allows for easy disassembly and replacement of the cutting blade 18.

[0050] After cutting is completed, the electric push rod 16 drives the stabilizing plate 17 and the cutting blade 18 to reset upwards to their initial positions. The second electric telescopic rod 13 drives the movable frame 14 to reset upwards, and the roller 15 no longer contacts the wire harness. The movable telescopic rod 5 drives the upper positioning plate 6 to reset upwards, loosening the fixation on the wire harness. The cut wire harness can then be taken out and prepared for the next cutting operation.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
