[0044] The second bevel gear 497 is arranged on the top of the first bevel gear 495, and the second bevel gear 497 is meshed with the first bevel gear 495. The first motor 494 is fixedly connected to the rectangular transmission rod 493 through the output shaft.

[0045] The first mounting plate 41 and the second mounting plate 42 are both provided with stabilizing plates 481 on their rear sides.

After the upper die 44 and the lower die 43 are adjusted, the stabilizing plates 481 are controlled to be inserted into the stabilizing grooves 482, which can improve the stability of the upper die 44 and the lower die 43.

[0046] The stabilizing grooves 482 are respectively distributed around the upper die 44 and the lower die 43 at equal intervals. The stabilizing plates 481 extend into the stabilizing grooves 482 and match the stabilizing grooves 482. The stabilizing grooves 482 distributed around the upper die 44 and the lower die 43 can be inserted with the stabilizing plates 481 after rotation adjustment. The front sides of the first mounting plate 41 and the second mounting plate 42 are fixedly connected to the auxiliary plates 484. The front side wall of the auxiliary plates 484 is rotatably connected to the fixing rod 485. The rectangular insert rod 491 passes through the fixing rod 491. Rod 485, the fixed rod 485 can rotate along with the rectangular insertion rod 491, the fixed rod 485 is internally slidably connected to the limit plate 486, the limit plate 486 extends into the interior of the rectangular insertion rod 491, the fixed rod 485 is internally rotatably connected with the threaded adjustment rod 487, the threaded adjustment rod 487 extends out of the outside of the fixed rod 485, the threaded adjustment rod 487 passes through the limit plate 486 and is threadedly connected to the limit plate 486, and the threaded adjustment rod 487 drives the fixed rod 485 to move horizontally after rotating.

[0047] The feeding assembly 5 includes a moving block 51, which is slidably connected to the inside of the track plate 3. A rectangular frame 52 is fixedly connected to the top of the moving block 51. A bracket plate 53 is provided on the top of the rectangular frame 52. The bracket plate 53 extends into the inside of the rectangular frame 52 and is slidably connected to the rectangular frame 52. One end of the bracket plate 53 is fixedly connected to a positioning frame 54. A positioning plate 55 is slidably connected to the positioning frame 54. A threaded control rod 56 is rotatably connected to the inside of the track plate 3. The threaded control rod 56 passes through the moving block 51 and is connected to the moving block 51 by threads. A second motor 57 is fixedly connected to the outside of the track plate 3. The second motor 57 is fixedly connected to one end of the threaded control rod 56 through an output shaft. After the second motor 57 is working, it drives the threaded control rod 56 to rotate;

[0048] The threaded control rod 56 drives the moving block 51 to move. The third electric push rod 58 is fixedly connected to the top of the moving block 51. The extension plate 59 is fixedly connected to the bracket plate 53. One end of the third electric push rod 58 is fixedly connected to the bottom of the extension plate 59. The fourth electric push rod 591 is fixedly connected to the top wall of the positioning frame 54. One end of the fourth electric push rod 591 is fixedly connected to the top of the positioning plate 55. After the third electric push rod 58 is working, it can push and pull the extension plate 59 up and down.

[0049] The second motor 57 then drives the threaded control rod 56 to rotate, and the threaded control rod 56 drives the moving block 51 to move, and the moving block 51 drives the rectangular frame 52 to move, and the rectangular frame 52 drives the bracket plate 53 to move, and the bracket plate 53 drives the positioning frame 54 to move, so as to transport the wire harness to the groove direction of the lower die 43. When the wire harness moves to the inside of the groove, the third electric push rod 58 pushes and pulls the extension plate 59, and the extension plate 59 drives the bracket plate 53 to move up and down, so as to adjust the height and ensure that the wire harness can touch the bottom smoothly and be placed inside the groove, so as to quickly realize the loading work, which saves more manpower than manual loading.

[0050] Before the above wiring harness is loaded, the matching pressing groove 45 and pressing block 46 are first adjusted according to the size of the wiring harness to be crimped. During adjustment, the first motor 494 works and drives the rectangular transmission rod 493 to rotate, the rectangular transmission rod 493 drives the sleeve 496 to rotate, the sleeve 496 drives the second bevel gear 497 to rotate, the second bevel gear 497 drives the first bevel gear 495 to rotate, the first bevel gear 495 drives the first round rod 48 to rotate, and the first round rod 48 drives the rectangular insertion rod 491 to rotate. At this time, the two rectangular insertion rods 491 respectively drive the upper pressing die 44 and the lower pressing die 43 to rotate. By adjusting the synchronous rotation of the upper pressing die 44 and the lower pressing die 43, the matching pressing groove 45 and pressing block 46 are adjusted to the corresponding upper and lower positions. After the second electric push rod 483 works, it pushes the stabilizing plate 481 to prompt the stabilizing plate 481 to be inserted into the stabilizing groove 482, thereby effectively ensuring the stability of the upper pressing die 44 and the lower pressing die 43 during the crimping process;

[0051] When the adjustment step is completed, the first electric push rod 499 works and pushes and pulls the U-shaped plate 498 up and down, and the U-shaped plate 498 drives the second mounting plate 42 to move. According to the above connection relationship, it can be seen that the height of the upper pressing die 44 can be adjusted in this way. When the upper pressing die 44 moves down to enter the pressing groove 45, the wire harness inside the pressing groove 45 can be crimped.

[0052] When it is necessary to replace the upper pressing die 44 and the lower pressing die 43 in the present device, the threaded adjustment rod 487 is rotated. After the threaded adjustment rod 487 drives the limit plate 486 to move away from the rectangular plug rod 491, the rectangular plug rod 491 can be directly pulled out. Due to the departure of the rectangular plug rod 491, the upper pressing die 44 and the lower pressing die 43 will lose the support limit of the rectangular plug rod 491. Therefore, at this time, the upper pressing die 44 and the lower pressing die 43 will fall off smoothly, so that the upper pressing die 44 and the lower pressing die 43 with different pressing grooves 45 or pressing blocks 46 can be replaced, which further enriches the crimping models that the present device can adapt to. Secondly, when the upper pressing die 44 or the lower pressing die 43 needs maintenance and needs to be replaced, it can also be conveniently replaced, thereby improving the adaptability and flexibility of the present device when used.

[0053] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
