[0027] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0029] In the specific implementation process, Figures 1-8 As shown, a wire harness pulling and loading device includes: a frame 1, a feeding assembly 29 provided on the frame 1, and a guide assembly. A pressing mechanism is provided on the upper side of the feeding assembly 29, and a tensioning adjustment mechanism is also provided between the frame 1. Multiple wire harnesses pass through the gap between the feeding assembly 29 and the pressing mechanism, the bottom side of the tensioning mechanism, and the interior of the guide assembly in sequence;

[0030] Specifically, such as Figure 1-5The two guide rails 4 are connected to each other by a screw thread, and the guide rails 4 are connected to the two guide rails 4 at the same time, so that the guide rails 4 can rotate relative to each other.

[0031] like Figure 5 As shown, the limiting plate 10 is provided with two circular holes 11, and the two movable rods 4 are movably disposed in the two circular holes 11 respectively;

[0032] It should be noted that a through hole 7 is provided in the middle of the wire pressing block 6, and a clamping block 8 is fixedly provided on the inner wall of the through hole 7. The clamping block 8 is adapted to the groove 5 provided on the side wall of the movable rod 4. When the wire pressing block 6 is installed on the movable rod 4, the clamping block 8 will be embedded in the groove 5 on the side wall of the movable rod 4. When the driving mechanism drives the movable rod 4 to rotate, the movable rod 4 can stably drive the wire pressing block 6 thereon to rotate;

[0033] Specifically, such as Figure 5 As shown, the driving mechanism includes a first gear 14, a second gear 15 and a driving motor 12. The driving motor 12 is fixedly mounted on a fixing bracket 13 provided on the side wall of the frame 1. The output end of the driving motor 12 movably passes through the fixing bracket 13 and is fixedly connected to the center of the first gear 14. The first gear 14 is meshed with the second gear 15, and the centers of the first gear 14 and the second gear 15 are respectively fixedly connected to the ends of the two movable rods 4. When the wiring harness needs to be fed, the driving motor 12 is started, and the driving motor 12 drives the first gear 14 to rotate, and the first gear 14 drives the second gear 15 to rotate. The two movable rods 4 rotate relative to each other, and the wire pressing block 6 on the movable rod 4 rotates accordingly, thereby pulling and feeding the wiring harness in the wire pressing groove 9;

[0034] Specifically, such as Figure 8As shown, the adjustment mechanism includes a rotating motor 16, a reciprocating screw rod 17 and a connecting rod 18. One side of the rotating motor 16 is fixedly connected to the side wall of the frame 1. The output end of the rotating motor 16 movably passes through the frame 1 and is fixedly connected to one end of the reciprocating screw rod 17. The other end of the reciprocating screw rod 17 is rotatably connected to the inner side wall of the frame 1. The reciprocating screw rod 17 is threadedly connected to the limit plate 10. The connecting rod 18 movably passes through the limit plate 10 and its two ends are rotatably connected to the inner walls on both sides of the frame 1.

[0035] It should be noted that, after the wire pressing block 6 on the movable rod 4 is installed, the position of the limit plate 10 needs to be adjusted to limit the wire pressing block 6 in the horizontal direction, and the rotating motor 16 is started to drive the reciprocating screw rod 17 to rotate. At this time, the limit plate 10 moves on the two movable rods 4, and the multiple wire pressing blocks 6 installed on the movable rod 4 are pressed to one side through the limit plate 10, so that the multiple wire pressing blocks 6 are fitted together;

[0036] Specifically, such as Figure 6 As shown, the pressing mechanism includes a pressing roller 19, the two ends of the pressing roller 19 are respectively slidably arranged in two through slots 20 opened on opposite sides of the frame 1, and two lifting mechanisms for driving the two ends of the pressing roller 19 to rise and fall synchronously are respectively provided on opposite sides of the frame 1;

[0037] The lifting mechanism includes a fixed block 21, a fixed frame 22 and a threaded rod 23. The center of the end of the pressure roller 19 is rotatably connected to the fixed block 21, and the fixed block 21 is slidably set in the fixed frame 22 set on the outer wall of the frame 1. The fixed block 21 is threadedly connected to the threaded rod 23. The upper and lower ends of the threaded rod 23 are respectively rotatably connected to the inner walls of the upper and lower sides of the fixed frame 22. A rotating motor 24 is fixedly installed on the top side of the fixed frame 22. The output end of the rotating motor 24 movably passes through the fixed frame 22 and is fixedly connected to the upper end of the threaded rod 23. When it is necessary to adjust the height of the pressure roller 19, the rotating motor 24 is started, and the rotating motor 24 drives the threaded rod 23 to rotate. At this time, the fixed block 21 can be driven to rise and fall in the fixed frame 22. The distance between the pressure roller 19 and the feeding assembly 29 can be adjusted according to the specifications of different wiring harnesses;

[0038] It should be noted that the feeding assembly 29 adopts a belt conveyor;

[0039] Specifically, such as Figure 1-3As shown, the tensioning mechanism includes a tensioning roller 25, and the two ends of the tensioning roller 25 are respectively slidably set in two slide grooves 28 opened on the opposite sides of the frame 1. Both ends of the tensioning roller 25 are fixedly connected with connecting plates 26. The bottom sides of the two connecting plates 26 are respectively fixedly connected to the output ends of two cylinders 27. The two cylinders 27 are respectively fixedly connected to the opposite sides of the frame 1. The height of the tensioning roller 25 can be adjusted by the cylinder 27 so that the wire harness is in an appropriate tension state to ensure that the wire harness is not too loose or too tight.

[0040] The working principle provided by the utility model is as follows: when it is necessary to process wire harnesses of different quantities and specifications, the fixed plate 2 is removed from one side of the frame 1, and the required number and size type of wire pressing blocks 6 are installed in the movable rod 4. After the installation is completed, the fixed plate 2 is fixed by bolts so that the ends of the two movable rods 4 are respectively inserted into the two slots 3 opened on the fixed plate 2. At this time, the rotating motor 16 is started, and the rotating motor 16 drives the reciprocating screw rod 17 to rotate. At this time, the limit plate 10 moves on the two movable rods 4, and the multiple wire pressing blocks 6 installed on the movable rod 4 are pressed to one side by the limit plate 10, so that the multiple wire pressing blocks 6 are fitted together. The device can flexibly adjust the number and size type of wire pressing blocks 6 according to processing requirements to adapt to wire harnesses of different quantities and specifications during the processing process. When processing the wire harness, multiple wire harnesses are passed through the gap between the feeding assembly 29 and the pressure roller 19, the bottom side of the tensioning roller 25 and the relatively arranged wire pressing blocks 6 in turn, and the drive motor 12 and the feeding assembly 29 are started to pull and load the wire harness.
