[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment provides an automotive wiring harness terminal crimping device. The automotive wiring harness terminal crimping device includes a processing base 1. A terminal crimping assembly 4 is provided at the rear end of the upper surface of the processing base 1. The terminal crimping assembly 4 includes a guide rod 407 fixedly installed on the rear side of the upper surface of the processing base 1. A limiting guide sleeve 408 is slidably sleeved on the outside of the guide rod 407. A crimping guide seat 405 is fixedly installed on the outside of the limiting guide sleeve 408.
[0028] A pressing seat 401 is fixedly installed on the lower end face of the pressing guide seat 405. A first pressing plate 403 and a second pressing plate 404 are detachably installed on the front end of the pressing seat 401. The lower end faces of the first pressing plate 403 and the second pressing plate 404 are provided with pressing grooves 409 in a figure-eight shape.
[0029] Specifically, a drive connector 406 is fixedly installed on the upper end face of the pressing guide seat 405. The drive connector 406 is used to assemble and connect the drive component. A pressing plate groove 402 is opened at the front end of the pressing seat 401. The size of the pressing plate groove 402 matches the width of the first pressing plate 403 and the second pressing plate 404.
[0030] Furthermore, the driving component can be a cylinder, hydraulic cylinder, etc., to drive the terminal pressing assembly 4 to press the wire harness 6 and the terminal 5. The pressing plate groove 402 can be assembled and disassembled with the first pressing plate 403 and the second pressing plate 404 through pins, so that pressing plates of different sizes and specifications can be replaced to press the wire harness 6 and the terminal 5.
[0031] Specifically, a terminal placement assembly 2 is provided at the middle position of the upper surface of the processing base 1. The terminal placement assembly 2 includes a placement seat 201 that is detachably installed at the middle position of the upper surface of the processing base 1. A terminal limiting assembly 3 is provided on the side wall of the placement seat 201. A placement plate groove 202 is provided on the front end surface of the placement seat 201. A first placement plate 203 and a second placement plate 204 are detachably installed inside the placement plate groove 202. A positioning pin 205 is provided at the middle position of the placement seat 201. A terminal 5 is sleeved on the outside of the positioning pin 205. A wire harness 6 is placed inside the terminal 5.
[0032] Furthermore, the first placement plate 203 is located at the front end of the second placement plate 204. The top of the first placement plate 203 is arc-shaped, and the middle of the top of the second placement plate 204 is arc-shaped, while the two sides are flat. The cooperation between the first placement plate 203 and the second placement plate 204 facilitates the placement and pressing of the terminal 5 and the wire harness 6. The arc-shaped design of the first placement plate 203 matches the lower end of the terminal 5, which can limit the terminal 5. The flat design of the upper surface of the second placement plate 204 improves the stability of the terminal 5 during placement, and the two arc-shaped designs reserve a certain amount of space for deformation during the pressing process of the terminal 5.
[0033] In use, select appropriate first placement plate 203 and second placement plate 204, and fix them in the placement plate groove 202 with pins. Fit the round hole at the top of terminal 5 onto the positioning pin 205. Place the rear end of terminal 5 on the upper end of the first placement plate 203 and second placement plate 204, and place the wire harness 6 inside terminal 5. When pressing is required, fix the first pressing plate 403 and second pressing plate 404 in the pressing plate groove 402 with pins. Connect them to the driving component via the driving connector 406. Start the driving component, which can drive the pressing seat 401 to move via the driving connector 406. The pressing seat 401 moves via the pressing guide seat 405 and the limiting... The guide sleeve 408 can slide up and down on the guide rod 407. The guide rod 407 serves as a guide, and the movement distance of the guide sleeve 408 on the guide rod 407 needs to be limited to avoid over-pressing. When the pressing seat 401 moves downward, it can drive the first pressing plate 403 and the second pressing plate 404 to move downward synchronously. In this way, the terminal 5 can be pressed through the pressing groove 409 at the bottom of the first pressing plate 403 and the second pressing plate 404. Through continuous pressing, the two ends of the terminal 5 can be folded inward, thereby pressing the wire harness 6 and the terminal 5 together, thus completing the pressing process of the wire harness 6 and the terminal 5.
[0034] Please see Figure 1 and Figure 3 The terminal limiting component 3 includes a fixed base 301 fixedly installed on the side wall of the placement base 201. The fixed base 301 has an assembly groove 302 inside. A spring limiting plate 304 is detachably installed at the right opening of the assembly groove 302. A pull rod 303 is slidably installed inside the assembly groove 302. A spring 305 is sleeved on the outer periphery of the pull rod 303. A limiting collar 306 located to the left of the spring 305 is fixedly installed on the pull rod 303. A limiting pressure plate 307 is fixedly installed on the pull rod 303.
[0035] Furthermore, there is a certain gap between the lower end face of the limiting pressure plate 307 and the placement seat 201, which facilitates the placement of the terminal 5 and, in turn, facilitates the limitation of the upper end face of the terminal 5, thereby improving the stability of the terminal 5 during pressing.
[0036] In use, pulling the pull rod 303 causes it to compress the spring 305 through the limiting sleeve 306. Simultaneously, with the cooperation of the spring limiting plate 304, the spring 305 contracts. The pull rod 303 can drive the limiting pressure plate 307 at the top to move away from the placement seat 201. At this time, the terminal 5 can be placed on the positioning pin 205, the first placement plate 203, and the second placement plate 204. After placement, releasing the pull rod 303 allows it to push the limiting sleeve 306 and the pull rod 303 to move under the elastic reset of the spring 305. The pull rod 303 drives the limiting pressure plate 307 to move to the end of the terminal 5 near the positioning pin 205, thereby limiting and compressing the terminal 5.
[0037] The terminal limiting component 3 can limit the compression of the terminal 5 through the limiting pressure plate 307, thereby preventing the terminal 5 from flying out during the pressing process and avoiding safety hazards.
[0038] In summary, the pressing grooves 409 at the bottom of the first pressing plate 403 and the second pressing plate 404 can achieve the pressing process of the wire harness 6 and the terminal 5. Therefore, the automatic positioning and pressing process of the wire harness 6 and the terminal 5 can be achieved through the cooperation of the terminal placement component 2, the terminal limiting component 3 and the terminal pressing component 4. The automated pressing process can reduce manual intervention, shorten operation time, and is suitable for mass production. The cooperation of the terminal placement component 2, the terminal limiting component 3 and the terminal pressing component 4 can ensure that the force, position and time of each pressing are consistent, achieve a high degree of consistency in product performance and reduce the defect rate.
