Description

Technical Field

[0001] This application relates to the technical field of automotive wire harnesses, and specifically to an automotive wire harness cutting device. Background Technique

[0002] The automotive wire harness is the main network of the automotive circuit. Without the wire harness, there would be no automotive circuit. A wire harness refers to a component formed by crimping contact terminals (connectors) made of copper with wires and cables, and then molding an insulator outside or adding a metal housing, etc., and bundling the wire harness to form a component for connecting the circuit. The wire harness industrial chain includes wires and cables, connectors, processing equipment, wire harness manufacturing, and downstream application industries. The wire harness has a very wide range of applications and can be used in automobiles, household appliances, computers, communication equipment, and various electronic instruments and meters. The body wire harness connects the entire body and generally has an H-shaped configuration;

[0003] During the production of automotive wire harnesses, it is necessary to cut the automotive wire harness blanks to make the wire harness length conform to the usage scenario. When cutting the wire harness, since most wire harnesses are made of flexible materials, they are prone to curling and bending. It is necessary for workers to tighten and press and position the wire harness before cutting to keep the wire harness taut, so as to facilitate subsequent cutting. As a result, the wire harness cutting efficiency is relatively low, and safety accidents caused by employee misoperations are likely to occur, and the safety performance is relatively poor. Therefore, an automotive wire harness cutting device is needed to improve the above problems. Utility Model Content

[0023] Embodiment

[0024] Please refer to Figures 1-3 , an automobile wire harness cutting device, including a workbench 1, and four legs 2 are symmetrically and fixedly installed at the bottom end of the workbench 1.

[0025] Please refer to Figures 1-3 , a pressing mechanism is provided on the workbench 1. The pressing mechanism includes a first mounting plate 3. The first mounting plate 3 is fixedly installed on the workbench 1. A motor 4 is fixedly installed on the first mounting plate 3. The output end of the motor 4 is fixedly installed with a screw rod 5. A threaded cylinder 6 is screwed on the screw rod 5. A pressing plate 7 is fixedly installed on the threaded cylinder 6. Two first limiting rods 8 are symmetrically and fixedly installed on the pressing plate 7. Two first sliding holes are symmetrically formed on the first mounting plate 3. Both of the two first limiting rods 8 are slidably connected to the first mounting plate 3. One end of the wire harness is placed below the pressing plate 7. By starting the motor 4, the motor 4 provides power to drive the screw rod 5 to rotate, so that the threaded cylinder 6 drives the pressing plate 7 to move, and the pressing plate 7 fixes one end of the wire harness.

[0026] Please refer to Figures 1-4, a cutting mechanism is provided on the workbench 1. The cutting mechanism includes a cutting tool 15. A second mounting plate 9 is fixedly installed on the workbench 1. An electric cylinder 10 is fixedly installed on the second mounting plate 9. A moving plate 11 is fixedly installed on the electric cylinder 10. By starting the electric cylinder 10, the moving plate 11 is pushed by the electric cylinder 10 to perform a moving operation. Two telescopic columns 12 are symmetrically and fixedly installed at the bottom end of the moving plate 11. The two telescopic columns 12 are connected by an auxiliary plate 14. Springs 13 are sleeved on the two telescopic columns 12. The two ends of the two springs 13 are respectively fixedly connected to the moving plate 11 and the auxiliary plate 14. Thus, the moving plate 11 drives the auxiliary plate 14 to perform a moving operation, making the auxiliary plate 14 contact the wire harness. The cutting tool 15 is located inside the auxiliary plate 14. The moving plate 11 is continuously pushed forward, so that the two telescopic columns 12 and the two springs 13 are compressed. Through the pressing of the auxiliary plate 14, the cutting tool 15 cuts the wire harness. Two second limit rods 16 are symmetrically and fixedly installed on the cutting tool 15. Two second sliding holes are symmetrically opened on the auxiliary plate 14. The two second limit rods 16 are respectively slidably connected to the two second sliding holes. Two fixing plates 17 are fixedly installed on the two second limit rods 16. The two fixing plates 17 are respectively connected to the moving plate 11 through a plurality of connecting bolts 18. When the cutting tool 15 needs to be replaced, the limiting operation of the plurality of connecting bolts 18 on the two fixing plates 17 is released, and the cutting tool 15 is slid to be disassembled, and a new cutting tool 15 is replaced, thus realizing the cutting operation of the wire harness.

[0027] Please refer to Figures 1-3 , a moving wheel 19 is provided at the bottom end of each leg 2. The installation of the plurality of moving wheels 19 facilitates the moving operation of the workbench 1.

[0028] Please refer to Figures 1-3 , an anti-slip pad 20 is provided at the bottom end of the pressing plate 7. The installation of the anti-slip pad 20 increases the friction force and makes the pressing plate 7 more stable.

[0029] Please refer to Figures 1-3 , it should also be noted that two stabilizing cylinders 21 are symmetrically and fixedly installed on the auxiliary plate 14. The two second limit rods 16 are respectively slidably connected to the two stabilizing cylinders 21. The installation of the two stabilizing cylinders 21 makes the movement of the two second limit rods 16 more stable.

[0030] Please refer to Figures 1-3 , sliders 22 are fixedly installed at both ends of the moving plate 11. Two limiting grooves are symmetrically opened on the second mounting plate 9. The two sliders 22 are respectively slidably connected to the two limiting grooves. The cooperation of the two sliders 22 and the two limiting grooves makes the movement of the moving plate 11 more stable.

[0031] In summary, when the automotive wire harness cutting device is in use, one end of the wire harness is passed through the second mounting plate 9 and placed under the pressing plate 7. The motor 4 is started. This motor is a well-known device for those skilled in the art that can be directly purchased on the market. Here, we only use it and do not make improvements to its structure and function. Therefore, we will not elaborate on it in detail here. Moreover, the motor is provided with a matching control switch, and the installation position of the control switch is selected according to actual usage requirements for the convenience of operation and control by the operator. The motor 4 provides power to drive the screw rod 5 to rotate. Then, under the limitation of the two first limiting rods 8, the threaded barrel 6 drives the pressing plate 7 to move, and the pressing plate 7 presses and fixes one end of the wire harness. The setting of the anti-slip pad 20 increases the friction force, making the pressing plate 7 more stable. The electric cylinder 10 is started, and the electric cylinder 10 pushes the moving plate 11 to move, so that the moving plate 11 drives the auxiliary plate 14 to move, making the auxiliary plate 14 contact the wire harness. Continuously push the moving plate 11 forward, so that the two telescopic columns 12 and the two springs 13 are compressed. The cutting tool 15 cuts the wire harness by pressing the wire harness with the auxiliary plate 14. When the cutting tool 15 needs to be replaced, the limiting operation of the plurality of connecting bolts 18 on the two fixing plates 17 is released, and the cutting tool 15 is slid and disassembled, and a new cutting tool 15 is replaced, thus realizing the cutting operation of the wire harness.
