Description

Technical Field

[0001] This utility model relates to the field of wire harness crimping technology, and specifically to a modular wire harness crimping device. Background Technology

[0002] In the field of wire harness manufacturing, wire harness crimping dies are indispensable tools. Their performance and efficiency directly affect the overall quality and production cost of wire harnesses. Crimping devices are used in the process of crimping pin terminals of wire harnesses. For example, a device for crimping pin terminals of wire harnesses is disclosed in a published Chinese patent document (application number: 202411300738.X). The pin terminals are first fixed to a feeding plate, and the pin terminals are transported between the upper and lower crimping dies by the feeding claws for crimping. During the long-term up-and-down sliding process of the upper crimping die, the gap gradually increases, which leads to displacement during the crimping process, resulting in a shorter service life and greater weight. Therefore, this technical solution is proposed to improve the process. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies where wire harnesses require frequent adjustments and have a short service life during the crimping process, and to provide a modular wire harness crimping device.

[0004] To achieve the above objectives, this utility model embodiment adopts the following technical solution: a modular wire harness crimping device, comprising a feeding structure and a stamping structure, wherein the stamping structure comprises a fixed plate, a mounting plate is provided on the working surface of the fixed plate, guide rails are provided opposite to each other on the working surface of the mounting plate, V-shaped grooves are provided on the sides of the two guide rails, a slider is provided between the two guide rails, a sliding member matching the V-shaped groove is provided on the side of the slider, and a crimping upper die for stamping is provided on the front of the slider.

[0005] Furthermore, the slider is a roller, which is fixedly disposed on the side of the slider, and the side of the roller is provided with a V-shaped inclined surface and a V-shaped groove for sliding connection.

[0006] Furthermore, the mounting plate is U-shaped, the guide rail is disposed on the inner side of the mounting plate, and the V-shaped groove is disposed along the length of the guide rail.

[0007] Furthermore, a lower pressing die for receiving and positioning is provided below the upper pressing die.

[0008] Furthermore, the feeding structure includes a feeding cylinder mounted on a fixed plate, a connecting block at the output end of the feeding cylinder, and a feeding gripper at the lower part of the connecting block.

[0009] Furthermore, the upper and lower parts of the connecting block are provided with sliding rods, and the cylinder body of the feeding cylinder is provided with a limiting groove for accommodating the sliding rods.

[0010] The beneficial effects of this utility model embodiment are as follows: The fixing plate provides a stable mounting foundation for the entire stamping structure. A mounting plate is provided on the working surface of the fixing plate, and two guide rails are installed on the inner side of the mounting plate. V-shaped grooves are provided on two opposite sides of the guide rails, extending vertically along the length of the guide rail. A sliding component matching the V-shaped groove is provided on the side of the slider. The sliding component is a roller, which is fixedly connected to the side of the slider.

[0018] The 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 for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0019] See Figures 1 to 6 This utility model discloses a modular wire harness crimping device, mainly composed of a feeding structure and a stamping structure. The stamping structure, as the core part, undertakes the crimping task of the wire harness pin terminals. It includes a fixing plate 1 mounted on a stamping machine, which provides a stable mounting base for the entire stamping structure. A mounting plate 4 is provided on the working surface of the fixing plate 1. The mounting plate 4 adopts a U-shaped design, which not only facilitates the installation of other components but also enhances the overall stability. On the working surface of the mounting plate 4, two guide rails 401 are arranged opposite each other, and these two guide rails 401 are installed on the inner side of the mounting plate 4. V-shaped grooves 403 are provided on the two opposite sides of the guide rails 401. The V-shaped grooves 403 extend vertically along the length of the guide rails 401, providing precise guidance for the subsequent sliding of the slider 402. A slider 402 is provided between two guide rails 401. The side of the slider 402 is provided with a sliding component that matches the V-shaped groove 403. The sliding component is a roller 404, which is fixedly connected to the side of the slider 402. The side of the roller 404 is provided with a V-shaped inclined surface, which is slidably connected to the V-shaped groove 403 on the guide rail 401. The slider 402 and the roller 404 have a certain length. Compared with the existing slider 402, the length of the slider 402 has been increased, making the sliding of the slider 402 on the guide rail 401 smoother and more stable, and the guidance more accurate. It reduces friction and wear during the sliding process, effectively avoiding the problem of displacement of the upper die 3 due to increased gap in the traditional device, and extending the service life of the device. In addition, the fixing plate 1 and the mounting plate 4 are made of lightweight aviation aluminum, which reduces the overall weight of the equipment and extends the overall service life of the equipment.

[0020] The front of the slider 402 is provided with a pressing upper die 3 for stamping. The pressing upper die 3 is a key component for pressing the wire harness pin terminals. Below the pressing upper die 3, there is a pressing lower die 301 for receiving and positioning. The pressing lower die 301 cooperates with the pressing upper die 3 to complete the pressing operation of the wire harness pin terminals. When the slider 402 slides on the guide rail 401 under the action of the press, it drives the pressing upper die 3 to move up and down, cooperating with the pressing lower die 301 to realize the pressing action.

[0021] The feeding structure, located on the left side of the fixed plate 1, is responsible for conveying the wire harness pin terminals to the crimping position. It includes a feeding cylinder 2 mounted on the fixed plate 1, which provides power for the feeding action. A connecting block 201 is located at the output end of the feeding cylinder 2, serving as a connection between the feeding cylinder 2 and the feeding gripper 202, transmitting power. The feeding gripper 202 is located below the connecting block 201, pushing the wire harness pin terminals and conveying them between the upper crimping die 301 and the lower crimping die 301, whereby one end of the wire harness is placed onto the pin terminal. The connection is fixed by crimping. To ensure the stability of the connecting block 201 and the feeding gripper 202 during the feeding process, slide rods 203 are provided on the upper and lower parts of the connecting block 201. Compared with the existing guide rail 401 in the moving direction of the connecting block 201, the overall weight is reduced. The cylinder body of the feeding cylinder 2 is provided with a limiting groove for accommodating the slide rod 203. The slide rod 203 slides in the limiting groove, which guides and limits the movement of the connecting block 201 and the feeding gripper 202, preventing them from deviating during the feeding process and ensuring that the wire harness pin terminals can be accurately delivered to the crimping position.

[0022] In actual use, the feeding structure first transports the wire harness pin terminals to the space between the upper crimping die 3 and the lower crimping die 301 via the feeding gripper 202. Then, the stamping structure begins operation. The feeding cylinder 2 stops, and the slider 402 slides on the guide rail 401, driving the upper crimping die 3 to move downwards, cooperating with the lower crimping die 301 to complete the crimping operation of the wire harness pin terminals. After crimping is completed, the upper crimping die 3 moves upwards to reset, and the feeding structure operates again, transporting the next wire harness pin terminal to the crimping position. This cycle repeats, achieving continuous crimping of the wire harness pin terminals, improving the quality and efficiency of wire harness pin terminal crimping, and extending the service life of the device.
