Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wire harness processing, specifically to a cutting device for automotive wire harness processing. Background Technology
[0002] As the nervous system of a vehicle, the precision and efficiency of automotive wiring harness processing directly affect the overall electrical performance and assembly quality of the vehicle. Cutting is an essential and critical step in the production of automotive wiring harnesses. Currently, common automotive wiring harness cutting devices typically include a fixed wire feeding mechanism and a cutting mechanism positioned at a specific location. After the wiring harness is pulled to a predetermined length by the wire feeding mechanism, the cutting mechanism, such as a hydraulically or pneumatically driven cutting blade, performs the cutting operation.
[0003] The position of the cutting mechanism is usually fixed, which means that when different lengths of wire harness are required or the cutting point needs to be adjusted, the entire wire harness often needs to be moved or the equipment needs to be readjusted. The operation is not flexible enough and affects the processing efficiency. At the moment of cutting, the wire harness is prone to shaking or displacement, especially when cutting at high speed. Utility Model Content
[0004] The purpose of this invention is to provide an automotive wiring harness processing and cutting device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive wiring harness processing and cutting device, comprising a processing table, a wire feeding mechanism disposed on the processing table, and a control center. The processing table has a groove, and a transmission screw is disposed on the processing table within the groove. A slide is sleeved on the transmission screw, and a hydraulic cylinder is disposed on the slide. The telescopic end of the hydraulic cylinder is provided with a cutting component for easy contact. An automotive wiring harness is wound on the wire feeding mechanism, and the automotive wiring harness passes through the processing table.
[0006] Preferably, the cutting assembly includes a mounting base, which is fixedly connected to the telescopic end of the hydraulic cylinder, and a cutting blade is provided at the bottom of the mounting base.
[0007] Preferably, both sides of the mounting base are provided with fixing plates, and guide rods are slidably inserted into the fixing plates, with abutment plates provided at the ends of the guide rods.
[0008] Preferably, an abutment spring is sleeved on the guide rod between the fixing plate and the abutment plate, and an arc-shaped fixing block is provided at the bottom of the abutment plate.
[0009] Preferably, mounting blocks are provided on both sides of the mounting base, and fans are mounted on the mounting blocks, with the airflow of the fans directed towards the cut-off point.
[0010] Preferably, a baffle is provided at the edge of the processing table, a material discharge port is provided on the processing table at the position covered by the baffle, and a collection box is provided on the processing table below the material discharge port.
[0011] Preferably, one end of the transmission screw is connected to a drive motor, and the slide and the transmission screw are connected by internal and external threads.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This utility model adopts a pre-tightening structure with an arc-shaped fixing block and abutment spring, which can stably clamp the wire harness before the cutting blade contacts the wire harness, effectively preventing the wire harness from shaking or shifting due to force at the moment of cutting. It is especially suitable for high-speed cutting scenarios, ensuring the flatness of the cut and the processing quality.
[0014] This utility model adopts an integrated fan cooling system to continuously deliver cooling airflow to the cutting area, effectively reducing the high temperature generated by the friction between the cutting blade and the wire harness, preventing the outer plastic of the wire harness from melting and sticking together or becoming stringy, and ensuring the smoothness of the cut. Through the coordinated design of the material drop port, collection box and baffle frame, the plastic debris generated during the cutting process is automatically collected, avoiding the splashing of cutting debris.

[0019] 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.
[0020] Please see Figures 1 to 3This utility model provides a technical solution: an automotive wiring harness processing and cutting device, including a processing table 1, a wire feeding mechanism 2 set on the processing table 1, and a control center. The processing table 1 has a groove 4. The wire feeding mechanism 2 is fixed at the starting end of the processing table 1. An automotive wiring harness 3 is wound on the wire feeding mechanism 2. The automotive wiring harness 3 is a B216 type wiring harness. The automotive wiring harness 3 passes through the processing table 1. The wire feeding mechanism 2 usually includes a drive wheel, a pressure wheel, etc., which are common devices in the prior art and are not shown in detail in the figure.
[0021] A transmission screw 5 is installed in the groove 4 on the processing table 1. A drive motor is fixedly connected to one end of the transmission screw 5. A slide 6 is sleeved on the transmission screw 5. The slide 6 and the transmission screw 5 are connected by internal and external threads. When the control center issues a command according to the required wire harness length, the drive motor starts and drives the transmission screw 5 to rotate. Since the slide 6 is connected to the transmission screw 5 by threads, the rotational motion of the transmission screw 5 is converted into the precise linear motion of the slide 6 along the length direction of the groove 4. The position of the slide 6 can be flexibly adjusted to any target cutting point as needed without moving the automotive wire harness 3.
[0022] A hydraulic cylinder 7 is fixedly installed on the slide 6. The telescopic end of the hydraulic cylinder 7 is provided with a cutting component for easy contact. The cutting component includes a mounting base 71, which is fixedly connected to the telescopic end of the hydraulic cylinder 7. A cutting blade 72 is fixedly installed at the bottom of the mounting base 71.
[0023] Both sides of the mounting base 71 are fixedly connected to a fixing plate 61. A guide rod 62 is slidably inserted into the fixing plate 61. An abutment plate 63 is fixedly connected to the end of the guide rod 62. An abutment spring 65 is sleeved on the guide rod 62 between the fixing plate 61 and the abutment plate 63. An arc-shaped fixing block 64 is fixedly connected to the bottom of the abutment plate 63.
[0024] When the extension end of the hydraulic cylinder 7 extends downward, driving the entire cutting assembly to move downward, the arc-shaped fixing blocks 64 on both sides will contact the automotive wiring harness 3 on the processing table 1 before the cutting blade 72. As the hydraulic cylinder 7 continues to press down, the abutment plate 63 and the arc-shaped fixing blocks 64 are subjected to the reaction force of the wiring harness 3, forcing the guide rod 62 to slide upward relative to the fixing plate 61, while compressing the abutment spring 65. The compressed abutment spring 65 generates a continuous downward elastic force, which, through the abutment plate 63 and the arc-shaped fixing blocks 64, stably and flexibly presses the wiring harness 3 onto the table surface of the processing table 1.
[0025] This process occurs before the cutting blade 72 contacts the wire harness 3. When the cutting blade 72 continues to move down and contacts the wire harness 3 and begins to cut, the two sides of the wire harness 3 are clamped by the arc-shaped fixing blocks 64 on both sides, which effectively prevents the wire harness from shaking due to force at the moment of cutting, and ensures the flatness and quality of the cut.
[0026] Mounting blocks 73 are fixedly connected to both sides of the mounting base 71. Fans 74 are mounted on the mounting blocks 73. The airflow of the fans 74 is directed towards the cutting point. During the cutting process, especially during high-speed cutting or continuous operation, the friction between the cutting blade 72 and the wire harness 3 will generate local high temperature. The fans 74 continuously blow cooling airflow into the cutting area, effectively reducing the temperature of the area and reducing the risk of the wire harness outer plastic melting and sticking to the blade edge or pulling into threads due to high temperature, thus ensuring a clean cut.
[0027] A baffle 9 is fixedly connected to the edge of the processing table 1. A material discharge port 11 is provided on the processing table 1 at the position covered by the baffle 9. A collection box 8 is attached to the processing table 1 below the material discharge port 11. Plastic debris generated during the cutting process is blown by the airflow of the fan and falls naturally under the action of gravity. The baffle 9 prevents the debris from splashing to the outside area of the processing table 1. Most of the debris will slide directly through the work surface into the material discharge port 11 and finally fall into the collection box 8 below. This design realizes automatic collection of debris, keeps the work area clean, and reduces the frequency of manual cleaning.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
