Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A cutting device for automotive wiring harness production includes a base plate 1. A fixing plate 2 is bolted to the top of the base plate 1. The top of the fixing plate 2 has a groove 3. Multiple feed pipes 4 are fixedly inserted into one side of the fixing plate 2, and multiple discharge holes 16 are provided on the other side of the fixing plate 2. The discharge holes 16, groove 3, and feed pipes 4 are connected. The top of the fixing plate 2 has multiple sliding grooves, and pressure columns 5 are slidably connected in the sliding grooves. The bottom end of the pressure column 5 has a pressure groove 11. A sliding shaft 6 is welded to the top of the pressure column 5. A spring 8 is sleeved on the top of the sliding shaft 6. A pressure head 7 is welded to the top of the sliding shaft 6. An installation device is bolted between the top ends of the two sides of the fixing plate 2. Mounting plate 13 has a pneumatic push rod 14 bolted to its top and a pressure plate 10 bolted to its bottom. The bottom of the pressure plate 10 contacts the pressure head 7. Under the tension of the pneumatic push rod 14, the pressure plate 10 moves downward, making it contact the pressure head 7. This, in turn, pushes the sliding shaft 6 and the pressure column 5 downward, causing the pressure groove 11 of the pressure column 5 to lock onto the wire harness, thus fixing the wire harness. A cutter 9 is bolted to the bottom of the pressure plate 10. The cutter 9 is located in the groove 3. Under the continued tension of the pneumatic push rod 14, the cutter 9 moves downward, thus cutting the wire harness.

[0024] Multiple guide posts 12 are welded to the top of the fixed plate 2. The pressure plate 10 is slidably sleeved with the guide posts 12 to guide the movement of the pressure plate 10 and improve the stability of wire harness cutting. Multiple receiving plates 15 are welded to one side of the fixed plate 2 to support the cut wire harness. The receiving plate 15 is located at one end of the discharge hole 16. Multiple support plates are welded to the top of the bottom plate 1. A placement roller 17 is rotatably inserted between every two support plates to support both ends of the wire harness. The fixed plate 2 is located in the middle of the multiple placement rollers 17.

[0025] The top of the base plate 1 is provided with a material conveying assembly 18, which includes two conveying rollers. Two support rods are welded to the top of the base plate 1. The conveying rollers are rotatably inserted between the two support rods. One end of the conveying roller is keyed with a gear, and the two gears mesh with each other. One side of one of the support rods is fixed with a motor by bolts. The output end of the motor is fixedly connected to one end of one of the conveying rollers. Driven by the motor and by the meshing of the two gears, the conveying roller is rotated, thereby conveying the cut wire harness. One end of the feed pipe 4 has a tapered structure.

[0026] The working principle of this embodiment is as follows: In use, one end of the wire harness is inserted into the feed pipe 4, passes through the groove 3, and is discharged from the discharge hole 16. Then, one end of the wire harness passes between the two conveying rollers, and both ends of the wire harness are placed on the placement rollers 17 on both sides of the fixed plate 2. Next, the pneumatic push rod 14 is activated. Under the tension of the pneumatic push rod 14, the pressure plate 10 is moved downward, so that the pressure plate 10 contacts the pressure head 7, thereby pushing the sliding shaft 6 and the pressure column 5 downward, so that the pressure groove 11 of the pressure column 5 is engaged on the wire harness. The wire harness is then fixed in place. Then, the pneumatic push rod 14 continues to extend, driving the cutter 9 downward to cut the wire harness. After cutting, the motor is started, and the conveyor roller rotates under the drive of the motor and the meshing of two gears, thus conveying the cut wire harness away. Then, the pressure plate 10 and the cutter 9 are retracted under the contraction of the pneumatic push rod 14, and the pressure column 5 and the sliding shaft 6 are reset under the action of the spring 8. Then, the remaining wire harness is cut according to the above steps.
