Description

Technical Field

[0001] This utility model relates to the field of wire harness terminal crimping technology, specifically to a multi-station crimping device adapted to crimping multiple specifications of wire harnesses. Background Technology

[0002] Automotive wiring harnesses are the main network components of a vehicle's electrical system. A wiring harness is an assembly consisting of copper-plated contact terminals (connectors) crimped to wires and cables, then covered with a molded insulator or an outer metal shell, and finally bundled together to form a connected circuit. The manufacturing process of automotive wiring harnesses involves inserting terminals into the harness and using external force to ensure a complete connection.

[0003] Currently, when bonding terminals to wire harnesses, the terminal is usually fitted onto the end of the wire harness, and then external force is used to clamp the terminal, causing it to deform and press it onto the end of the wire harness. Since there are many different specifications of wire harnesses and terminals in automobiles, and the specifications and diameters of various terminals are also different, as are the specifications of the wire harnesses to be pressed, it is necessary to develop suitable molds for pressing different specifications of wire harnesses and terminals. The existing method is to use a stamping machine to press the same specification of terminal and then change to the next mold for pressing. Therefore, it is necessary to change molds frequently, which increases the number of operation steps, occupies a certain amount of production time, and reduces production efficiency. Therefore, this technical solution is proposed to improve the process. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, which requires frequent mold changes during the crimping process of different specifications of automotive wire harnesses and terminals, thus affecting production efficiency, and to provide a multi-station crimping device suitable for crimping multiple specifications of wire harnesses.

[0005] To achieve the above objectives, this utility model embodiment adopts the following technical solution: a multi-station crimping device adapted to crimping multiple specifications of wire harnesses, including a base fixed on a stamping device, a sliding groove provided on the upper part of the base, a driving groove provided on the bottom of the sliding groove, a movable plate provided inside the sliding groove, a mounting seat provided on the bottom of the movable plate along the length direction, the mounting seat being slidably disposed inside the driving groove, a driving device provided on the lower part of the base and connected to the mounting seat, and multiple crimping dies of different specifications provided on the upper part of the movable plate along the length direction.

[0006] Furthermore, the two sides of the movable plate are inclined surfaces that cooperate with the two sides of the sliding groove, and multiple rollers are provided on the bottom surface of the sliding groove.

[0007] Furthermore, the driving device is a drive motor located at the lower part of the base, the output end of the drive motor is provided with a drive gear, the drive gear is located on the side of the drive groove, and the side of the mounting base is provided with a rack connected to the drive gear.

[0008] Furthermore, the upper part of the mounting base is provided with a back plate, the front of the back plate is provided with a guide groove, and the side of the pressing mold is provided with a guide block that is slidably disposed inside the guide groove.

[0009] Furthermore, the pressing mold includes a receiving seat disposed on the upper part of the movable plate, a positioning groove for a positioning terminal is provided on the upper part of the receiving seat, a pressing block is disposed above the receiving seat, and an adjusting rod for adjusting the distance between the pressing block and the receiving seat is provided on the upper part of the pressing block.

[0010] The beneficial effects of this utility model embodiment are as follows: A mounting base is provided at the bottom of the movable plate along the length direction, and the mounting base is slidably disposed inside the drive groove. A drive device is provided at the lower part of the base, and multiple rollers are provided on the bottom surface of the sliding groove. The rollers greatly reduce the friction between the movable plate and the bottom surface of the sliding groove, making the movable plate move more easily. When the drive motor starts, its output end drives the drive gear 301 to rotate. The meshing action of the drive gear and the rack converts the rotational motion into linear motion, thereby driving the mounting base to slide in the drive groove, and then driving the movable plate to move in the sliding groove. This drive method has a simple structure and high transmission efficiency. In addition, the drive motor uses a stepper motor, which can accurately control the moving position of the movable plate, thereby realizing the conversion between different specifications of crimping dies. By setting multiple crimping dies of different specifications and corresponding drive and guide structures, the function of quickly switching between different specifications of crimping dies is realized, effectively solving the problem of frequent die changes required by traditional crimping methods, improving production efficiency, reducing production costs, and meeting the needs of multi-specification wire harness crimping in automotive wire harness production.

[0019] 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.

[0020] See Figures 1 to 7 This utility model discloses a multi-station crimping device adapted to crimping multiple specifications of wire harnesses. It mainly includes a base 1 fixed on a stamping device. The base 1 serves as the basic support structure of the entire device, providing stable support and positioning, and providing installation space for the crimping die 5. A sliding groove 2 is provided on the upper part of the base 1, and a driving groove 202 is provided at the bottom of the sliding groove 2. A movable plate 101 is slidably disposed inside the sliding groove 2. A mounting seat 102 is provided along the length direction at the bottom of the movable plate 101, and the mounting seat 102 is slidably disposed inside the driving groove 202. A driving device is provided at the lower part of the base 1. This driving device is connected to... The mounting base 102 is connected and used to drive the movable plate 101 to move within the sliding groove 2. To ensure the smoothness and stability of the movable plate 101's movement within the sliding groove 2, the two sides of the movable plate 101 are designed as inclined surfaces, which cooperate with the two inclined surfaces of the sliding groove 2. At the same time, multiple rollers 201 are provided on the bottom surface of the sliding groove 2. The rollers 201 greatly reduce the friction between the movable plate 101 and the bottom surface of the sliding groove 2, allowing the movable plate 101 to slide more easily and smoothly within the sliding groove 2. This reduces energy loss and equipment wear caused by friction, and improves the service life and operating efficiency of the device.

[0021] The driving device uses a drive motor 3 located at the bottom of the base 1. The output end of the drive motor 3 is equipped with a drive gear 301, which is located on the side of the drive groove 202. The bottom of the sliding groove 2 is provided with a space to accommodate the drive gear 301, and the side of the mounting base 102 is provided with a rack 302. The drive gear 301 and the rack 302 are connected to each other. When the drive motor 3 starts, its output end drives the drive gear 301 to rotate. The meshing action of the drive gear 301 and the rack 302 converts the rotational motion into linear motion, thereby driving the mounting base 102 to slide in the drive groove 202, and then driving the moving plate 101 to move in the sliding groove 2. This driving method has a simple structure and high transmission efficiency. In addition, the drive motor 3 uses a stepper motor, which can accurately control the moving position of the moving plate 101, thereby realizing the conversion between different specifications of pressing dies and ensuring that the pressing die 5 of the required specifications can accurately reach the working position.

[0022] Multiple crimping dies 5 of different specifications are arranged on the upper part of the movable plate 101 along the length direction. These crimping dies 5 are components for crimping wire harnesses and terminals of different specifications. When crimping of wire harnesses and terminals of specific specifications is required, the movable plate 101 is driven by the drive device to move in the sliding groove 2, so that the crimping die 5 of the corresponding specification moves to the working position of the stamping device, thereby realizing quick switching without frequent die replacement. The upper part of the mounting base 102 is provided with a back plate 4. The front of the back plate 4 is provided with a guide groove 401. The side of the crimping die 5 is provided with a guide block 402. The guide block 402 is slidably arranged in the guide groove 401. The cooperation between the guide groove 401 and the guide block 402 provides a stable guiding effect for the crimping die 5, ensuring that the crimping die 5 can maintain the correct position and posture during movement and crimping, avoiding crimping quality problems caused by shaking or offset, and improving the accuracy and consistency of crimping.

[0023] The specific structure of the crimping die 5 includes a receiving seat set on the upper part of the moving plate 101. The upper part of the receiving seat is provided with a positioning groove for positioning terminals, which is used to accurately place and position the terminals to ensure that the terminals are accurately positioned during the crimping process. A crimping block is set above the receiving seat, and an adjusting rod is set on the upper part of the crimping block. The distance between the crimping block and the receiving seat can be changed by adjusting the knob on the adjusting rod. The receiving seat and the crimping block can have different specifications to adapt to the crimping requirements of different specifications of wire harnesses and terminals. In actual operation, according to the specifications of the wire harness and terminals, the adjusting rod is adjusted to make the distance between the crimping block and the receiving seat reach a suitable value. Then, the stamping device is started to make the crimping block move downward to crimp the terminals and wire harnesses, achieving a firm connection. By setting multiple crimping dies 5 of different specifications and corresponding drive and guide structures, the function of quickly switching between different specifications of crimping dies 5 is realized, effectively solving the problem of frequent die changes required by traditional crimping methods, improving production efficiency, reducing production costs, and meeting the needs of multi-specification wire harness crimping in automotive wire harness production.
