In the production process of automobile wire harnesses, multiple steps of processing are required, and among them, it is necessary to cut long wires into required lengths.

[0003] In the prior art, when the wire harness is conveyed to the vicinity of the cutting tool by a transmission device, the wire harness often shifts, and even some wire harnesses will be bent after being unrolled from a coil. In this state, the cut will be inclined and uneven after direct cutting, affecting subsequent assembly operations. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By arranging multiple shaping mechanisms suitable for various types of wire harnesses in a circular manner on the surface of the rotating seat, the corresponding shaping mechanism is adjusted to be directly below the cutting mechanism according to the wire harness model, and then the wire harness is sent into the first U-shaped groove from one side of the shaping block. The first U-shaped groove combined with the cover plate can constrain the wire harness to be straight, and the first motor drives the driving gear to rotate, and the driving gear drives the corresponding first driven gear to rotate, so that the worm at the bottom of the shaping block where the wire harness is placed can be rotated, and then the worm wheels on both sides of the wire harness are driven to rotate in opposite directions, thereby driving the corresponding shaping rollers to rotate.

At the same time, the breaking component inside the correction block is offset against the breaking component at the bottom of the pressure plate, and the push rod on the surface of each crimping box pushes the piston block in the other crimping box into the air cavity where it is located, thereby compressing the air inside the crimping box. After the air pressure is increased, the pins distributed on the curved surface of the crimping box are pushed outward, and then the insulation on both sides of the cut part of the wire harness is pierced with a circle of holes, which makes it easier for the operator to remove the insulation at the wire end during subsequent assembly, improving the linkage consistency of the equipment.

[0031] Refer to Figures 1-9 , an automobile wire harness cutting device, which includes a base 1. On both sides of the top of the base 1, a first stop block 2 and a second stop block 3 are fixedly installed. In the middle of the top of the base 1, a device bracket 5 with a U-shaped structure is fixedly installed. On the top of the device bracket 5, a hydraulic telescopic rod 6 is fixedly installed. A cutting mechanism 7 is provided at the telescopic end of the hydraulic telescopic rod 6. A rotating seat 18 with a polygonal prism structure is rotatably installed between the first stop block 2 and the second stop block 3. A blanking groove is opened at the center of one end of the rotating seat 18. A feeding auger 19 is rotatably installed in the blanking groove. Multiple wire harness shaping mechanisms suitable for multiple models of wire harnesses are respectively provided on multiple planes of the rotating seat 18; each wire harness shaping mechanism includes a shaping block 14 and a cover plate 15. A first U-shaped groove 1401 adapted to the outer diameter of the wire harness is opened in the middle of the top of the shaping block 14. A plurality of second U-shaped grooves 1402 are symmetrically opened on both sides of the first U-shaped groove 1401. A shaping roller 24 that abuts against the wire harness is rotatably installed in each second U-shaped groove 1402; the cutting mechanism 7 includes a lifting plate 701. A plurality of first springs 702 are fixedly installed at the bottom of the lifting plate 701. The bottom ends of the plurality of first springs 702 are fixedly installed with a pressing plate 704. A chute is opened in the middle of the top of the pressing plate 704. A cutting knife 703 is slidably installed in the chute. The top of the cutting knife 703 is fixedly installed with the bottom of the lifting plate 701. Two wire skin breaking components 705 are symmetrically provided on the top of the pressing plate 704.

[0032] When in use, multiple shaping mechanisms suitable for various types of wire harnesses are arranged in a circular pattern on the surface of the rotating seat 18, and the corresponding shaping mechanism is adjusted to be directly below the cutting mechanism 7 according to the wire harness model, and then the wire harness is sent into the first U-shaped groove 1401 from one side of the shaping block 14. The first U-shaped groove 1401 combined with the cover plate 15 can constrain the wire harness to be straight, and a protrusion is provided at the bottom of the cover plate 15 that abuts against the wire harness. The first motor 8 drives the active gear 17 to rotate, and the active gear 17 drives the corresponding first driven gear 16 to rotate, which can make the worm 22 at the bottom of the shaping block 14 where the wire harness is placed rotate, and then drive the worm gears 23 on both sides of the wire harness to rotate in the opposite direction, and then drive the corresponding shaping rollers 24 to rotate. The shaping rollers 24 on both sides of the wire harness can shape the wire harness while simultaneously conveying the wire harness to the other end of the first U-shaped groove 1401, effectively avoiding the wire harness from being bent or offset when cut, and improving the flatness of the wire harness incision.

[0033] In this embodiment, the skin breaking component 705 includes a wire pressing box 7051, which is fixedly installed at the bottom of the pressure plate 704. One side of the wire pressing box 7051 is an open structure, and the other side of the wire pressing box 7051 is provided with an arc-shaped groove adapted to the wiring harness. A sealing cover 7052 is fixedly installed in the open end of the wire pressing box 7051, and a sealed cavity is formed inside the wire pressing box 7051. A cylindrical air cavity 7053 is provided in the wire pressing box 7051, and one end of the air cavity 7053 is connected to the sealed cavity and the other end is connected to the outside of the wire pressing box 7051. A piston block 7054 is slidably installed in the air cavity 7053, and a second spring 7057 is fixedly installed on one end of the piston block 7054 near the sealing cover 7052. The other end of the second spring 7057 is fixedly installed with the sealing cover 7052. A plurality of pins 7056 are installed in a circular and uniform sliding manner in the arc groove, and the tip of each pin 7056 is facing the center of the arc groove. A third spring 7058 is sleeved on the surface of each pin 7056. A push rod 7055 is fixedly installed on one side of the wire pressing box 7051. A positioning hole 1403 for the cutter 703 to pass through is provided in the middle of the top of the correction block 14. Two wire pressing holes 1404 are symmetrically provided on the top of the correction block 14. A skin-breaking component 705 is fixedly installed in each wire pressing hole 1404. The upper and lower skin-breaking components 705 are rotationally symmetrical. When the two skin-breaking components 705 are against each other, the corresponding two arc grooves surround the wiring harness and the push rod 7055 pushes the corresponding piston block 7054 into the inside of the wire pressing box 7051 to increase the internal air pressure of the wire pressing box 7051.

[0034] When the cutting mechanism 701 is used, the two skin-breaking components 705 at the bottom of the pressure plate 704 press the wire harness tightly, further making the wire harness stable when being cut, and improving the flatness of the wire harness end after the equipment cuts the wire. At the same time, the skin-breaking component 705 inside the correction block 14 is against the skin-breaking component 705 at the bottom of the pressure plate 704, and the push rod 7055 on the surface of each pressure box 7051 pushes the piston block 7054 in the other pressure box 7051 into the air cavity 7053 where it is located, thereby compressing the air inside the pressure box 7051. After the air pressure is increased, the pins 7056 distributed on the arc surface of the pressure box 7051 are all pushed outward, and then the insulation on both sides of the cut part of the wire harness is pierced through a circle of holes, which makes it easy for the operator to remove the insulation at the wire end during subsequent assembly, and improves the linkage consistency of the equipment;

[0035] Compared with directly cutting off the insulation at the wire end, the use of dense puncture has another advantage, that is, the insulation at the wire end is already in a state that can be easily removed. The reason for not removing it is to protect the internal copper wire and prevent the exposed wire ends from being damaged or severely bifurcated during the transportation process, which is not conducive to subsequent direct use in assembly.

[0036] In this embodiment, a groove 1405 is provided at the bottom of each correction block 14, and a plurality of worm gears 23 are symmetrically provided under each groove 1405. The plurality of worm gears 23 are rotatably mounted on the surface of the rotating seat 18. Two worms 22 are rotatably mounted on each surface of the rotating seat 18. A protective box 21 is provided between the ends of the two worms 22. The interior of the protective box 21 is a hollow structure and is fixedly mounted on the surface of the rotating seat 18. Each plane of the rotating seat 18 is provided with a discharge hole 20 connected to the discharge trough. Each discharge hole 20 is aligned with the corresponding protective box 21 and the positioning hole 1403. The ends of the two worms 22 are connected by a connecting shaft. The plurality of worm gears 23 are respectively meshed with the two worms 22. The first driven gear 16 and the second driven gear 25 are respectively fixedly mounted on the far end of the two worms 22. A circular avoidance groove is provided on the adjacent side of the first stop block 2 and the second stop block 3. The driving gear 17 and the third driven gear 26 are respectively rotatably mounted in the two avoidance grooves. The wheel 17 is meshed with the first driven gear 16, and the third driven gear 26 is meshed with the second driven gear 25. The driving pulley 11 and the driven pulley 13 are rotatably installed on one side of the second stop block 3. A synchronous belt 12 is sleeved between the driving pulley 11 and the driven pulley 13. The rotation center of the driven pulley 13 is fixedly connected to the rotation center of the feeding auger 19 through a connecting shaft. The rotation center of the driving pulley 11 is fixedly connected to the rotation center of the third driven gear 26 through a connecting shaft. One side of the second stop block 3 is provided with a second slag receiving groove 302 communicated with the discharge trough, and the other side of the second stop block 3 is provided with a first slag receiving groove 301 connected to the second slag receiving groove 302. A slag collecting box 10 is detachably installed in the first slag receiving groove 301. The first motor 8 and the second motor 9 are fixedly installed on one side of the first stop block 2. The output end of the first motor 8 is fixedly mounted on the rotation center of the driving gear 17, and the output end of the second motor 9 is fixedly mounted on the rotation center of the rotating seat 18. An outer skin 4 is riveted between the first stop block 2 and the second stop block 3.

[0037] When in use, the first motor 8 drives the driving gear 17 to rotate, and the driving gear 17 drives the first driven gear 16 meshing with it, and then drives the worm 22 in the shape correction mechanism for placing the wire harness to rotate, and then the worm wheels 23 on both sides of the worm 22 mesh and rotate, and then drive the corresponding shape correction roller 24 to rotate, so that the shape correction roller 24 can shape the wire harness while conveying the wire harness to move, and the rotation of the worm 22 simultaneously drives the second driven gear 25 to rotate, and the second driven gear 25 drives the third driven gear 26 to rotate, and the third driven gear 26 drives the driving belt The wheel 11 rotates, and the active pulley 11 drives the driven pulley 13 to rotate through the synchronous belt 12, and the driven pulley 13 drives the feeding auger 19 to rotate. The debris residue generated by the cutting line of the cutting mechanism 7 falls into the discharge trough through the positioning hole 1403, the protective box 21 and the discharge hole 20, and is then transported to the second slag receiving trough 302 through the rotating feeding auger 19, and then falls into the slag collecting box 10 in the first slag receiving trough 301, which is convenient for centralized processing, effectively avoiding the debris splashing around the equipment during the cutting process, and improving the safety and convenience of the equipment.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
