[0020] The rotating mechanism includes a positioning column 8 rotatably connected to the workbench 1, the lower end of the positioning column 8 is fixedly connected to a motor 4, the motor 4 is fixedly set on the ground, the upper end of the positioning column 8 is fixedly connected to a top plate 9, and one side of the top plate 9 is fixedly connected to a positioning rod 10.

[0021] A hydraulic cylinder 11 is provided at the top of the positioning rod 10, and the output end of the hydraulic cylinder 11 passes through the positioning rod 10 and is fixedly connected to a fixed plate 12. A crimping plate 15 is provided below the fixed plate 12, and a sliding rod 14 is symmetrically fixedly connected to the top of the crimping plate 15. The sliding rod 14 is slidably connected to the fixed plate 12, and a spring 13 is symmetrically provided between the fixed plate 12 and the crimping plate 15. The upper end of the spring 13 is fixedly connected to the fixed plate 12, and the lower end of the spring 13 is fixedly connected to the crimping plate 15.

[0022] When in use, first place the two ends of the wire harness on the two fixing blocks 3 respectively, fix the wire harness through the fixing mechanism 2, and then control the hydraulic cylinder 11 to crimp one end of the wire harness through the crimping plate 15. After the crimping is completed, the positioning column 8 is driven to rotate through the rotating mechanism, thereby driving the crimping plate 15 to rotate to the top of the other end of the wire harness, and then repeat the crimping operation to achieve fully automatic crimping.

[0023] The fixing mechanism 2 includes two threaded rods 7, a pressure plate structure, and a pressure structure. The threaded rods 7 are rotatably arranged inside the fixing block 3. The fixing block 3 is symmetrically provided with fixing grooves 5. The lower ends of the threaded rods 7 are rotatably connected to the bottom of the fixing grooves 5. The outsides of the two threaded rods 7 are both threadedly connected with connecting plates 19. The ends of the two connecting plates 19 facing each other are connected to the pressure plate structure.

[0024] The pressure plate structure is composed of a plurality of limit plates 16 which are assembled in sequence. The limit plates 16 are arc-shaped and are detachably connected to each other. The limit plates 16 are located on the same plane and are concentrically arranged. The limit plates 16 are plugged and fixed in sequence by protrusions 17 .

[0025] Specifically, a groove 18 is formed at the lower end of the limiting plate 16 , and the protrusion 17 is inserted into the groove 18 .

[0026] The pressure structure is arranged at the top of the fixed block 3. The pressure structure and the pressure plate structure cooperate with each other. The pressure structure is formed by stacking a plurality of plates 6 in sequence. The plates 6 are L-shaped, and the two ends of the plates 6 are arranged parallel to the top surface of the fixed block 3. The two ends of the wire harness are placed on the two pressure structures respectively. As the sizes of the two ends of the wire harness are different, the plates 6 and the limit plates 16 of the corresponding sizes can be taken out or installed according to the sizes of the two ends of the wire harness, so that wire harnesses of different sizes can be applied.

[0027] Working principle:

[0028] When fixing the two ends of the wire harness, the two ends of the wire harness are placed on two pressure structures respectively. As the sizes of the two ends of the wire harness are different, the corresponding size of the plate 6 and the limit plate 16 can be taken out or installed according to the size of the two ends of the wire harness, so that wire harnesses of different sizes can be used. Then, the two threaded rods 7 are rotated at the same time, and the two connecting plates 19 and the pressure plate structure move downward as a whole. The pressure structure and the pressure plate structure are used together to fix the wire harness.

[0029] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
