Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, and in particular to a workbench for processing automotive wire harnesses. Background Technology

[0002] Wiring harnesses form the neural network of an automotive electrical system, and their processing quality directly impacts the vehicle's electrical performance and safety. In the processing of automotive wiring harnesses, the workbench is the core platform for operations such as fixing, positioning, separating, and cutting the harnesses. Cutting coiled cables into the required lengths is an essential and frequently performed step in the process. An efficient, precise, and user-friendly workbench is crucial for improving wiring harness processing efficiency and ensuring product quality.

[0003] However, traditional workbenches used for cutting automotive wire harnesses have some significant limitations. First, securing the wire harnesses effectively is often inconvenient and unstable, especially for harnesses of different specifications. The lack of flexible and reliable clamping mechanisms makes it easy for the harnesses to shift or loosen during operation, affecting the accuracy of subsequent operations. Second, when cutting wire harness segments of different lengths, operators mainly rely on manually measuring and marking positions using tools such as measuring tapes before cutting. This method is not only inefficient but also prone to introducing human measurement errors in batch processing, leading to inconsistent cut lengths, material waste, or defective products. Frequent manual measurement and positioning also increase the workload of operators. Utility Model Content

Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0021] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0022] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0023] This utility model provides the following: Figure 1-5The workbench for processing automotive wire harnesses shown includes a support platform 1. A fixed support plate 2 and two side support plates 3 are fixedly connected to the support platform 1 on both sides of the fixed support plate 2. A wire harness fixing mechanism 4 is provided on the top of the fixed support plate 2 and the two side support plates 3. A right-angle top plate 5 is fixedly connected to the support platform 1 behind the fixed support plate 2 and the two side support plates 3. A dual-axis motor 6 is fixedly connected to the top of the right-angle top plate 5. A lead screw 7 is provided at each of the two output ends of the dual-axis motor 6. A lead screw sleeve 8 is threadedly connected to the lead screw 7. A limiting slider 9 is fixedly connected to the bottom of the lead screw sleeve 8, passing through the top wall of the right-angle top plate 5 and slidingly connected to the right-angle top plate 5. A positioning ruler plate 10 is fixedly connected to the bottom of the limiting slider 9. A drive motor 11 is provided below the positioning ruler plate 10. The drive motor 11 is connected to the positioning ruler plate 10 through a first telescopic rod 12. A cutting blade 13 is provided at the output end of the drive motor 11.

[0024] like Figure 1-4 As shown, in this utility model, the bottom of the support platform 1 is fixedly connected to four support columns 14, and the four support columns 14 are distributed in a rectangular shape at the four corners of the bottom of the support platform 1, which ensures the stability of the support platform 1 and makes the workbench stable and not easy to shake when performing wire harness processing operations.

[0025] like Figure 5 As shown, the wire harness fixing mechanism 4 of this utility model includes a fixing sleeve 401 set on the top of the fixing support plate 2 and the two side support plates 3. Multiple second telescopic rods 402 are fixedly connected to the outside of the fixing sleeve 401. The movable shaft of the second telescopic rod 402 passes through the side wall of the fixing sleeve 401 and is fixedly connected to the clamping block 403. By extending and retracting the second telescopic rod 402, the clamping block 403 can be moved, thereby realizing adaptive and stable clamping of wire harnesses of different specifications and avoiding wire harness displacement or loosening during the cutting process.

[0026] like Figure 5 As shown, in this utility model, the number of second telescopic rods 402 is not less than three and they are arranged in a ring array on the outside of the fixed sleeve 401, which can make the wire harness subject to uniform clamping force in all directions, further improving the stability and reliability of wire harness clamping.

[0027] like Figure 1-4 As shown, in this utility model, the top of the right-angled top plate 5 is fixedly connected to the bearing seat 15, and the end of the lead screw 7 away from the dual-axis motor 6 is connected to the bearing seat 15, so that the lead screw 7 can rotate stably under the drive of the dual-axis motor 6, reducing the shaking and offset of the lead screw 7 during rotation, and ensuring the accuracy and stability of the lead screw 7 transmission.

[0028] like Figure 1-4As shown, the right-angled top plate 5 of this utility model is provided with a limiting groove on its top wall for the limiting slider 9 to pass through and slide. By setting the limiting groove, on the one hand, a precise track is provided for the sliding of the limiting slider 9, so that the limiting slider 9 can only move along the direction of the limiting groove, avoiding unnecessary shaking and offset of the lead screw sleeve 8 during the rotation of the lead screw 7. On the other hand, through the cooperation of the limiting slider 9 and the limiting groove, the rotation of the lead screw sleeve 8 is effectively restricted, ensuring that the lead screw sleeve 8 can only move in a straight line along the lead screw 7, thereby realizing the precise movement of the positioning ruler plate 10.

[0029] like Figure 2 and Figure 3 As shown, in this utility model, two guide sliders 16 are fixedly connected to the top of the positioning ruler plate 10. The bottom of the top wall of the right-angle top plate 5 is provided with a guide groove for the guide sliders 16 to slide. The cooperation between the guide sliders 16 and the guide groove further enhances the stability and accuracy of the movement of the positioning ruler plate 10.

[0030] like Figure 1-4 As shown, in this utility model, the front side of the top wall of the right-angle top plate 5 is provided with a scale strip and the front end of the positioning ruler plate 10 is located at the scale strip. The side of the positioning ruler plate 10 and the cutting blade 13 are on the same vertical plane, so that the operator can intuitively determine the position of the positioning ruler plate 10 through the scale strip according to the required wire harness length, and then accurately control the cutting position of the cutting blade 13.

[0031] Working principle: In practical implementation, the coiled cable is first passed through the fixed sleeve of the wire harness fixing mechanism at the top of the fixed support plate and the side support plate. The second telescopic rod is activated, causing its movable shaft to extend and drive the clamping blocks to move towards the wire harness until multiple clamping blocks clamp the wire harness evenly from different directions, achieving a stable clamping of the wire harness and adapting to wire harnesses of different specifications.

[0032] Based on the required wire harness length, the operator observes the scale strip on the front side of the right-angle top plate and starts the dual-axis motor. The dual-axis motor drives the lead screw to rotate, and the screw sleeve is threaded onto the lead screw. Because the limiting slider cooperates with the limiting groove on the top wall of the right-angle top plate, the lead screw sleeve can only move in a straight line along the lead screw, thereby driving the positioning ruler plate to move. At the same time, the guide slider slides in the guide groove, further ensuring the stability and accuracy of the positioning ruler plate's movement, so that the front end of the positioning ruler plate moves to the position on the scale strip corresponding to the required cutting length.

[0033] After positioning is complete, the drive motor is started, which drives the cutting blade to rotate. Then, the first telescopic rod extends, causing the cutting blade to descend and contact the wire harness, completing the trimming of the required length. After trimming, the first telescopic rod retracts, causing the cutting blade to rise and return to its original position, allowing for the next trimming operation. This cycle repeats, achieving efficient and precise wire harness trimming.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
