Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, specifically a traction device for automotive wire harness processing. Background Technology

[0002] Traditional traction devices often have fixed or manually adjustable traction wheel spacing. When processing wire harnesses of different diameters (such as low-voltage thin wire harnesses and high-voltage thick wire harnesses), frequent changes of specialized clamps or disassembly and adjustment components are required. This is not only cumbersome and time-consuming, but also increases the equipment investment cost for enterprises. It is difficult to meet the flexible production needs of various wire harnesses. Furthermore, some devices use a "head-pulling" traction method, which forcibly drags the wire harness by clamping the end, which can easily cause the copper core inside the wire harness to stretch and deform or the insulation layer to tear, thus failing to meet the requirements of the production line. Therefore, those skilled in the art provide a traction device for automotive wire harness processing to solve the problems mentioned in the background art. Utility Model Content

A limit groove is formed on the lower surface of the slider, and the receiving plate is slidably connected to the slider through the limit groove. A ventilation component is provided on the surface of the receiving plate, and a transmission component is provided on the receiving plate.

[0005] Furthermore, the ventilation assembly includes a solenoid valve, an air injection pipe, and a sealing ring. The air injection pipe is fixedly connected to the surface of the receiving plate, and the solenoid valve is provided on the surface of the air injection pipe. The air injection pipe is interconnected with the pneumatic chamber, and the sealing ring is provided on the surface of the slider, and the sealing ring abuts against the inner wall of the pneumatic chamber.

[0006] Furthermore, the transmission assembly includes a servo motor, a transmission wheel, and a transmission shaft. The servo motor is fixedly connected to the upper surface of the receiving plate, and the output end of the servo motor is provided with a transmission shaft. One end of the transmission shaft is rotatably connected to the receiving plate through a bearing, and the transmission wheel is fixedly connected to the surface of the bearing.

[0007] Furthermore, the transmission assembly also includes a transmission rod, a driven wheel, and a transmission belt. The transmission rod is rotatably connected to the base plate via bearings, the driven wheel is fixedly connected to the surface of the transmission rod, and a transmission belt is provided on the driven wheel and the transmission wheel.

[0008] Furthermore, a fixed shaft is fixedly connected to the upper surface of the slider, and an auxiliary wheel is rotatably connected to the upper end of the fixed shaft.

[0009] Furthermore, a power wheel is fixedly connected to the upper end of the transmission rod, and a wire harness to be processed is arranged between the power wheel and the auxiliary wheel.

[0010] By adopting the above technical solution Compared with the prior art, the beneficial effects of this utility model are: 1. By combining the structure of the pneumatic chamber drive slider, the position of the slider (i.e. the distance between the auxiliary wheel and the power wheel) can be adjusted to adapt to automotive wiring harnesses of different diameters (such as conventional low-voltage wiring harnesses, high-voltage thick wiring harnesses, etc.), thereby ensuring that multiple types of wiring harnesses can be traction processed without changing special fixtures, improving the versatility of the device and reducing the equipment investment cost for enterprises. 2.

The limiting block 14 is welded to the upper surface of the receiving plate 2 to form an initial limiting for the slider 10.

[0014] In this embodiment, the ventilation assembly includes a solenoid valve 7, an air injection pipe 8, and a sealing ring 12. The air injection pipe 8 is fixedly connected to the surface of the receiving plate 2, and the solenoid valve 7 is provided on the surface of the air injection pipe 8. The air injection pipe 8 is interconnected with the pneumatic chamber 11. The surface of the slider 10 is provided with a sealing ring 12, and the sealing ring 12 abuts against the inner wall of the pneumatic chamber 11. The pneumatic chamber 11 is embedded in a preset position on the receiving plate 2. The slider 10 is slidably connected to the protruding slide rail of the receiving plate 2 through the bottom limiting groove 13, so that the slider 10 can move smoothly along the length direction of the receiving plate 2. The sealing ring 12 is nested on one edge of the slider 10 to ensure that it abuts tightly against the inner wall of the pneumatic chamber 11 to form a sealed space. One end of the air injection pipe 8 is connected to the pneumatic chamber 11, and the other end is connected to an external air source. The solenoid valve 7 is connected in series in the middle of the air injection pipe 8 to control the on / off of the air source and the air volume adjustment.

[0015] In this embodiment, the transmission assembly includes a servo motor 6, a transmission wheel 15, and a transmission shaft 16. The servo motor 6 is fixedly connected to the upper surface of the receiving plate 2. The output end of the servo motor 6 is provided with the transmission shaft 16. One end of the transmission shaft 16 is rotatably connected to the receiving plate 2 via a bearing. The transmission wheel 15 is fixedly connected to the surface of the bearing. The transmission assembly also includes a transmission rod 17, a driven wheel 18, and a transmission belt 19. The transmission rod 17 is rotatably connected to the base plate 1 via a bearing. The driven wheel 18 is fixedly connected to the surface of the transmission rod 17. The transmission belt 19 is provided on the driven wheel 18 and the transmission wheel 15. A fixed shaft 9 is fixedly connected to the upper surface of the slider 10. An auxiliary wheel 3 is rotatably connected to the upper end of the fixed shaft 9. A power wheel is fixedly connected to the upper end of the transmission rod 17. 5. A wire harness 4 to be processed is set between the power wheel 5 and the auxiliary wheel 3; the servo motor 6 is fixed to the upper surface of the receiving plate 2 through the motor base, and its output end is connected to the transmission shaft 16. The other end of the transmission shaft 16 is rotatably connected to the bearing seat inside the receiving plate 2 through the bearing. The transmission wheel 15 is keyed to the middle of the transmission shaft 16. The transmission rod 17 is vertically installed in the preset hole position of the base plate 1 through the bearing. The driven wheel 18 is keyed to the lower end of the transmission rod 17. The transmission belt 19 is sleeved between the transmission wheel 15 and the driven wheel 18 to form a transmission fit. The fixed shaft 9 is vertically welded to the upper surface of the slider 10. The auxiliary wheel 3 is rotatably connected to the upper end of the fixed shaft 9 through the bearing. The power wheel 5 is keyed to the upper end of the transmission rod 17 to ensure that the power wheel 5 and the auxiliary wheel 3 are in the same vertical plane.

[0016] By adjusting the solenoid valve 7 through the control system, compressed air of different pressures is injected into the pneumatic chamber 11 when processing fine or thick wire harnesses, causing it to push the slider 10 to move to the right. This ensures that there is always an inward clamping force between the auxiliary wheel 3 and the power wheel 5. When passing through the wire harness, the power wheel 5 can drive the wire harness to move. The clamping force is adjusted by controlling the density of the internal air to ensure continuous adaptation to the size of the wire harness 4 to be processed. The sealing ring 12 ensures stable air pressure to lock the gap. There is no need to change the clamp. The servo motor 6 is started, and the torque is transmitted to the transmission rod 17 through the transmission shaft 16, transmission wheel 15, belt, and driven wheel 18, driving the power wheel 5 to rotate. The friction force drives the wire harness forward. The auxiliary wheel 3 rotates synchronously to change the sliding friction to rolling friction, avoiding damage to the wire harness. The wire harness is continuously conveyed forward and fed to external cutting machines, terminal machines, and other equipment.

[0017] By combining the structure of the pneumatic chamber 11 driving the slider 10, the position of the slider 10 (i.e., the distance between the auxiliary wheel 3 and the power wheel 5) can be adjusted to adapt to automotive wire harnesses of different diameters (such as conventional low-voltage wire harnesses, high-voltage thick wire harnesses, etc.), thus ensuring that multiple types of wire harnesses can be traction processed without changing special fixtures, improving the versatility of the device and reducing the equipment investment cost for enterprises. The auxiliary wheel 3, which is rotatably connected to the slider 10 through the fixed shaft 9, forms a clamping engagement with the power wheel 5 at the upper end of the transmission rod 17. When the wire harness 4 to be processed is placed between the two, the auxiliary wheel 3 can drive the wire harness to move, continuously driving the wire harness forward and feeding it into the external processing equipment. Compared with the traditional head pulling method, this process greatly reduces the probability of internal damage to the wire harness, avoids tearing of the copper core or insulation layer of the wire harness, and ensures the electrical performance and appearance quality of the wire harness after processing.
