[0019] Referring to Figure 1-Figure 9 , an automobile wire harness cutting device includes a base 1. On both sides of the top of the base 1, a first stopper 2 and a second stopper 3 are fixedly installed. In the middle of the top of the base 1, a device bracket 5 in 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.

Multiple wire harness shaping mechanisms suitable for multiple types 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 abutted 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 skin-breaking components 705 are symmetrically provided at the top of the pressing plate 704.

[0020] During use, by arranging a plurality of wire harness shaping mechanisms suitable for multiple types of wire harnesses to be circumferentially distributed on the surface of the rotating seat 18, the corresponding wire harness shaping mechanism is adjusted to directly below the cutting mechanism 7 according to the wire harness type. Then, the wire harness is fed 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 and straighten the wire harness. A convex block abutted against the wire harness is provided at the bottom of the cover plate 15. By driving the driving gear 17 to rotate through the first motor 8, the driving gear 17 drives the corresponding first driven gear 16 to rotate, and further enables the worm 22 at the bottom of the shaping block 14 where the wire harness is placed to rotate, and further drives the worm wheels 23 on both sides of the wire harness to rotate in the reverse direction, and further drives the corresponding shaping rollers 24 to rotate. While the shaping rollers 24 on both sides of the wire harness shape the wire harness, they can also convey the wire harness to move towards the other end of the first U-shaped groove 1401, effectively avoiding the wire harness from being in a bent or offset state during cutting, and improving the flatness of the cut of the wire harness.

[0021] In this embodiment, the skin breaking component 705 includes a wire pressing box 7051, which is fixedly installed at the bottom of the pressing 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 wire harness. A sealing cover 7052 is fixedly installed in the open part 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 at one end of the piston block 7054 near the sealing cover 7052, and the other end of the second spring 7057 is fixedly installed with the sealing cover 7052. The arc A plurality of thumbtacks 7056 are evenly and evenly installed in the arc groove in a circular manner, and the tip of each thumbtack 7056 faces the center of the arc groove. A third spring 7058 is sleeved on the surface of each thumbtack 7056. A push rod 7055 is fixedly installed on one side of the wire pressing box 7051. A positioning hole 1403 is provided in the middle of the top of the correction block 14 for the cutter 703 to pass through. 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 symmetrically arranged. 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.

[0022] When in use, by setting the cutting mechanism 7, when the lifting plate 701 descends to cut the wire harness, first, the two skin-breaking components 705 at the bottom of the pressing plate 704 press the wire harness, further making the wire harness stable when cutting, and improving the flatness of the end of the wire harness after the equipment cuts the wire. At the same time, the skin-breaking component 705 inside the correction block 14 abuts against the skin-breaking component 705 at the bottom of the pressing plate 704, and the push rod 7055 on the surface of each wire pressing box 7051 pushes the piston block 7054 in another wire pressing box 7051 into the air cavity 7053 where it is located, thereby compressing the air inside the wire pressing box 7051. After the air pressure is enhanced, the pins 7056 distributed on the arc surface of the wire pressing box 7051 are all pushed outward, and then the insulating skin on both sides of the wire harness cutting place is pierced with a circle of holes, which is convenient for the operator to easily remove the insulating skin at the wire end during subsequent assembly, and improves the linkage consistency of the equipment; Compared with directly cutting off the insulation at the wire end, the densely punched hole method has another advantage, that is, the insulation at the wire end is already in a state where it can be easily removed. The reason why it is not removed is to protect the internal copper wire and prevent the exposed wire ends from being damaged or severely bifurcated during transportation, which is not conducive to subsequent direct assembly.

[0023] 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 below each groove 1405. The plurality of worm gears 23 are rotatably installed on the surface of the rotating seat 18. Two worms 22 are rotatably installed on each surface of the rotating seat 18.

A driving pulley 11 and a 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 with the rotation center of the feeding auger 19 through a connecting shaft, and the rotation center of the driving pulley 11 is fixedly connected with the rotation center of the third driven gear 26 through a connecting shaft. A second slag receiving groove 302 connected to the feeding trough is provided on one side of the second stop block 3, and a first slag receiving groove 301 connected to the second slag receiving groove 302 is provided on the other side of the second stop block 3.

The output end of the first motor 8 is fixedly installed with the rotation center of the driving gear 17, and the output end of the second motor 9 is fixedly installed with 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.

[0024] 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 therewith, thereby driving 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, thereby driving the corresponding shape correction rollers 24 to rotate, so that the shape correction rollers 24 shape the wire harness while conveying the wire harness to move, the rotation of the worm 22 simultaneously drives the second driven gear 25 to rotate, 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.
