All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] Depend on Figures 1 to 4 The present invention discloses a multi-stage spring-compression type wire harness straightening device, comprising a bracket 1 and a straightening main rod 2. The straightening main rod 2 is fixedly connected to one end of the bracket 1. A disc 3, a wire feeding wheel 4, and a switch assembly 5 are sequentially arranged on one side of the bracket 1. A wire feeding comb 6, a guide wheel 7, a longitudinal straightening assembly 8, a transverse straightening assembly 9, and a tensioning assembly 10 are arranged on the straightening main rod 2. The longitudinal straightening assembly 8 and the transverse straightening assembly 9 are arranged with a 90-degree offset structure. The wire harness 11 passes through the disc 3, the wire feeding wheel 4, the switch assembly 5, the wire feeding comb 6, the guide wheel 7, the tensioning assembly 10, the longitudinal straightening assembly 8, and the transverse straightening assembly 9 in sequence.
[0021] The wire harness enters the wire feeding wheel 4 through the disc 3, then passes through the switch assembly 5 and enters the wire feeding comb 6. The wire harness is tensioned by the tensioning assembly 10, and finally straightened in two different directions by the longitudinal straightening assembly 8 and the transverse straightening assembly 9. The other end of the wire harness can be pulled by the continuous traction device.
[0022] Both the longitudinal straightening assembly 8 and the transverse straightening assembly 9 consist of three fixed-point straightening wheels 12, a positioning pressure plate 13, two adjusting screws 14, an adjusting knob 15, a spring 16, and two movable straightening wheels 17. The straightening main rod 2 has a T-shaped through groove 18. The adjusting screw 14 passes through the T-shaped through groove 18 and is threadedly connected to it. The adjusting knob 15 is fixedly connected to one end of the adjusting screw 14. The positioning pressure plate 13 is slidably sleeved on the end of the adjusting knob 15 near the adjusting screw 14. The spring 16 is sleeved on the adjusting screw 14 and located between the straightening main rod 2 and the positioning pressure plate 13. The fixed-point straightening wheels 12 are rotatably connected to the side of the straightening main rod 2. The movable straightening wheels 17 are rotatably connected to the side of the positioning pressure plate 13 and are offset from the fixed-point straightening wheels 12.
[0023] The longitudinal straightening component 8 and the transverse straightening component 9 can be adjusted according to the diameter of the wire harness. During adjustment, the adjustment knob 15 is rotated, which drives the adjustment screw 14 to rotate. The adjustment screw 14 is threadedly connected to the straightening main rod 2, thereby adjusting the position of the positioning pressure plate 13. The positioning pressure plate 13 drives the two movable straightening wheels 17 to move synchronously. The spring 16 can achieve elastic clamping to avoid overpressure damage or incomplete straightening.
[0024] The switch assembly 5 consists of a wire feeding block 19, a switch piece 20, a screw 21, and a switch body 22. The wire feeding block 19 and the switch body 22 are both fixedly connected to the bracket 1. The switch piece 20 is connected to the wire feeding block 19 by the screw 21, which can determine whether the wire harness passes through. The model of the switch body 22 is CX-SX674WR.
[0025] The wire feeding comb 6 is connected to the straightening main rod 2 through the wire feeding comb frame 23 and the wire feeding comb adjustment nut 24, and can comb the wire bundle;
[0026] The tensioning assembly 10 consists of an L-shaped support plate 25, a limiting guide rail 26, a slide block 27, a second spring 28, and a tensioning wheel 29. The L-shaped support plate 25 is fixedly connected to the straightening main rod 2. The limiting guide rail 26 is fixedly connected to one side of the L-shaped support plate 25. The slide block 27 is slidably connected to the limiting guide rail 26. The second spring 28 is connected between the slide block 27 and the L-shaped support plate 25. The tensioning wheel 29 is rotatably connected to the slide block 27.
[0027] The wire harness passes through the tensioning wheel 29, and the tensioning force can be applied by the spring 28. The limiting guide rail 26 and the slide 27 can provide movable support for the tensioning wheel 29. By tensioning the wire harness, the straightening stability of the wire harness can be improved.
[0028] In operation, the longitudinal and transverse straightening components, consisting of three fixed-point straightening wheels, a positioning pressure plate, two adjusting screws, an adjusting knob, a spring, and two movable straightening wheels, can be adjusted according to the wire harness diameter, improving adaptability. Spring clamping prevents overpressure damage or incomplete straightening, thus improving the straightening effect. The tensioning component, consisting of an L-shaped support plate, a limit guide rail, a slide, a spring, and a tensioning wheel, can tension the wire harness, preventing slackness and incomplete straightening, and providing stability to the straightening process.
