[0002] The wiring harness is a wiring component that connects various electrical devices in the circuit. The wiring harness is generally composed of an insulating sheath, a terminal, a wire and an insulating wrapping material. A wire harness crimping machine is usually used in the production process of the wire harness. The terminal is deformed by extrusion to make it firmly connected to the wire. China has authorized a utility model patent (Announcement No.: CN221467011U) to disclose a crimping machine for processing wire harness terminals. Through the cooperation between the limit block, the fixed frame, the guide rod, the card plate, the spring and the sleeve, the effect of quickly installing and disassembling the template is achieved, which solves the problem that the lower mold of some wire harness terminal processing crimping machines is relatively fixed and inconvenient to replace, reduces the difficulty of installation and disassembly, and improves the efficiency of replacement.

[0003] There are still some shortcomings in the use of the above-mentioned device: specifically, in the prior art, a fixing frame for fixing the template is fixed on the side wall of the fixed template, and the template is disassembled by operating the structure on the fixing frame to separate the fixing frame from the limit block. However, since the template and the fixing frame are fixedly connected, replacing the template means that the original fixing frame and the structure on the fixing frame cannot be reused, resulting in waste. At the same time, when producing templates, each template must be equipped with a fixing frame, which increases the production cost. Therefore, a crimping machine for wire harness production is proposed in view of the above situation. Utility Model Content

[0004] The utility model provides a crimping machine for wire harness production, which has the advantages that no waste of other structures will be caused when replacing the template, and the relevant structures for positioning the template can be reused.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An operating rod is rotatably matched on the through hole, the operating rod is inserted into the assembly groove and fixedly connected with a bidirectional screw, and one end of the bidirectional screw away from the operating rod is rotatably matched with the round hole.

[0008] There are two moving blocks, and the two moving blocks are provided with threaded holes with opposite thread directions. The tops of the two moving blocks are fixedly connected with L-shaped rods, and the two L-shaped rods are matched with the L-shaped grooves. The two moving blocks are respectively matched with the bidirectional screw threads through the threaded holes, and the two moving blocks are slidably matched with the assembly grooves.

[0009] A template is placed in the placement groove, and a row of mold cavities are provided on the top and bottom of the template, with seven mold cavities in each row. Positioning grooves are provided on both sides of the outer wall of the template, and the positioning grooves cooperate with the L-shaped rods. There are two positioning grooves on each side.

[0010] Preferably, a bracket is provided on the top of the base, and four through holes are opened through the top of the bracket.

[0011] Preferably, four cylinders are arranged on the top of the bracket, the moving ends of the four cylinders pass through the through holes, and the passing ends of the moving ends of the four cylinders are fixedly connected with a pressing plate.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model adopts the design of structures such as placement grooves, assembly grooves, L-shaped grooves, bidirectional screws and L-shaped rods.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4 A crimping machine for wire harness production includes a base 1 and a moving block 4. A placement groove 101 is provided on the top of the base 1, an assembly groove 102 is provided on the bottom of the base 1, one side of the inner wall of the assembly groove 102 has a round hole, L-shaped grooves 103 are provided on both sides of the inner wall of the placement groove 101, and the L-shaped groove 103 is connected to the assembly groove 102.

[0028] In the present embodiment, when in use, after the template 6 is placed in the placement groove 101 and initially limited, the bidirectional screw 3 is driven to rotate by rotating the operating rod 2. The rotation of the bidirectional screw 3 causes the two movable blocks 4 to move relative to each other, and then the two movable blocks 4 are brought closer, so that the L-shaped rod 5 slides in the L-shaped groove 103, and the L-shaped rod 5 is inserted into the positioning groove 602, thereby further fixing the template 6.
