Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to a cutting tool for cutting automotive wiring harnesses. Background Technology

[0002] In automotive wiring harness production, wiring harnesses typically consist of multiple wires of different colors and specifications to meet various electrical connection requirements. Traditional wiring harness cutting relies primarily on manual labor or semi-automatic equipment. Operators must identify wire colors according to process requirements, manually adjust cutting lengths, and then cut the wires. This method is inefficient; manually identifying wire colors and adjusting cutting parameters is time-consuming and unsuitable for mass production. Furthermore, manual operation is prone to errors in wire color identification or cutting length due to visual fatigue or misjudgment, affecting wiring harness assembly accuracy and increasing defect rates. In addition, traditional cutting equipment typically cannot automatically adapt to the cutting requirements of different colored wires, necessitating frequent adjustments to equipment parameters when changing product specifications, increasing production complexity.

[0003] Currently, some automated cutting equipment exists on the market, but most can only cut to a fixed length and cannot automatically adjust cutting parameters according to the wire color, still requiring manual intervention. A few devices with color recognition capabilities rely on complex optical detection systems, which are costly and have weak resistance to interference from factors such as surface reflection and dirt on the wire, affecting recognition stability. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a cutting fixture, primarily used for automotive wiring harness cutting operations. It can identify wires of different colors within the wiring harness and then cut these wires to different lengths, thereby improving operational efficiency while ensuring high yield.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cutting fixture, including an operating table, a housing first and a housing second are provided above the operating table, a cutting slit is provided between the housing first and the housing second, and a cutting blade and a color recognizer are provided below the housing second.

[0006] As a further improvement to the above technical solution:

[0007] The inner side of the housing is provided with a downwardly extending baffle, and the outer side is provided with an extension plate, the extension plate being provided with a positioning groove.

[0008] The positioning groove is a semi-open groove, and its front end face coincides with the center line of the cutting gap.

[0009] A shelf is provided below the first baffle, and the shelf is coaxially distributed with the cutting gap.

[0010] A baffle is provided on the inner side of the housing 2, and a clearance groove corresponding to the position of the cutting blade is provided on the baffle 2.

[0011] The number of cutting blades is multiple and they are evenly distributed along the length of the worktable, and each cutting blade is equipped with a drive source.

[0012] The beneficial effects of this utility model embodiment are as follows: The cutting fixture includes an operating table, with a housing 1 and a housing 2 above the operating table, and a cutting slit between the housing 1 and the housing 2. A cutting blade and a color identifier are provided below the housing 2. Compared with the conventional method of manually identifying colors and then cutting according to a set length, this method can reduce the eye strain of operators, alleviate work fatigue, and avoid confusion in cutting lengths when there are wires of similar colors. This improves product production efficiency and ensures production yield. Attached Figure Description

[0018] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0019] like Figure 1-2As shown, the cutting fixture in this embodiment includes an operating table 1. A housing 2 and a housing 3 are positioned above the operating table 1, with a cutting slit 4 between them. A cutting blade 5 and a color recognizer 6 are positioned below the housing 3. Multiple cutting blades 5 are evenly distributed along the length of the operating table 1. Each cutting blade 5 is equipped with a drive source 13, which is a hydraulic push rod. A controller, electrically connected to the color recognizer 6 and the drive source 13, is installed inside the operating table 1. When a wire from a wire harness is placed in the cutting slit 4, the color recognizer 6 will collect the signal. The color of the wire is fed back to the controller, which then sends a work signal to the drive source 13 at different locations to cut the wire. The different colored wires in the wire harness are then cut to their set lengths to facilitate subsequent assembly and wiring. Compared with the conventional method of manually identifying the color and then cutting to the set length, this method reduces the eye strain on operators, alleviates work fatigue, and avoids confusion in cutting lengths when there are wires of similar colors. This improves production efficiency and ensures a high yield rate.

[0020] like Figure 3 As shown, a downwardly extending baffle 7 is provided on the inner side of the housing 2, and an extension plate 8 is installed on the outer side wall. A positioning groove 9 for fixing the wire harness connector is installed on the extension plate 8. The positioning groove 9 is a semi-open groove, and the front end face coincides with the center line of the cutting gap 4. The semi-open groove facilitates the removal of the wire harness connector. After the wire harness connector is placed in the positioning groove 9, the coaxial distribution of the wire and the cutting gap is ensured, reducing cutting errors and improving cutting accuracy.

[0021] like Figure 4 As shown, a shelf 10 is installed below the baffle 7. The shelf 10 is coaxially distributed with the cutting gap 4. One side of the shelf 13 has a vertical plate that is flush with the baffle 7, and the other side abuts against the lower end face of the baffle 11. The arrangement of the baffle 7, the vertical plate, the baffle 11 and the shelf 10 can ensure that the wire 14 will not be skewed when it falls into the cutting gap 4, which can improve the accuracy of the cutting length.

[0022] The inner side of the housing 2 3 is provided with a baffle 2 11. The baffle 2 11 is provided with a clearance groove 12 corresponding to the position of the cutting blade 5. There are multiple shelves 11 and clearance gaps are reserved between two adjacent shelves 11, which are distributed in accordance with the position and number of clearance grooves 12, so as to facilitate the cutting blade 5 to cut the wire.

[0023] The working principle / assembly process of this solution: Both housing 1 (2) and housing 2 (3) are U-shaped, and their two ends are detachably connected to the two sides of the workbench 1 by bolts. A cutting gap 4 is reserved between housing 1 (2) and housing 2 (3) for placing wires. A color recognizer 6 and a cutting blade 5 are installed inside housing 2 (3). There are multiple cutting blades 5, which are evenly distributed along the length of the workbench 1. Each cutting blade 5 is equipped with a hydraulic push rod as a drive source 13. A controller that is electrically connected to the color recognizer 6 and each drive source 13 is installed inside the workbench 1. The color recognizer 6 identifies the color of the wire to be cut and then sends a work signal to the corresponding drive source 13 to complete the differentiated cutting operation of wires of different colors.
