[0022] When in actual use, first pull the second rotating wheel 7 upwards, and the pulling of the second rotating wheel 7 causes the slider 5 to slide upwards in the sliding groove 4 through the second rotating shaft 6. The movement of the slider 5 compresses the height adjustment spring 8. Then, after one end of the wire harness is overlapped on the top of the first rotating wheel 3, the second rotating wheel 7 is released. Under the elastic action of the height adjustment spring 8, the second rotating wheel 7 is pressed against the top of the wire harness, so that the wire harness is clamped between the first rotating wheel 3 and the second rotating wheel 7. When the motor 15 drives the first rotating shaft 2 and the second rotating shaft 6 to rotate at the same speed in different directions, the first rotating wheel 3 and the second rotating shaft 6 are rotated in the same direction. The wheel 7 also rotates in different directions at the same speed, thereby pulling the wire harness. The wire harness production traction device achieves the function of adjusting the distance between the first rotating wheel 3 and the second rotating wheel 7 by rotating the second rotating shaft 6 to the surface of the slider 5, sliding the slider 5 to the slide groove 4 opened on the surface of the frame 1, and fixing the height adjustment spring 8 between the slider 5 and the inner wall of the slide groove 4, thereby achieving the function of adjusting the distance between the first rotating wheel 3 and the second rotating wheel 7, and ensuring that the second rotating wheel 7 can be pressed against the top of the wire harness at any height, thereby achieving the function of pulling wire harnesses of different diameters through the wire harness production traction device.
[0023] Embodiment 2
[0024] On the basis of embodiment 1, in order to enable the slider 5 to move only in the vertical direction in the slide groove 4, a guide rail 9 is opened on the inner wall of the slide groove 4, and two groups of guide rails 9 are provided. The two groups of guide rails 9 are symmetrically distributed about the slider 5, and guide plates 10 are fixed on the two symmetrical end faces of the slider 5.

[0025] A guide rail 9 is provided on the surface of the chute 4 , and a guide plate 10 is fixed on the surface of the slider 5 . The slider 5 is guided by the cooperation of the guide rail 9 and the guide plate 10 , so that the slider 5 can only move in the vertical direction in the chute 4 .
[0026] Embodiment 3
[0027] On the basis of the second embodiment, in order to realize the rotational motion of the first rotating shaft 2 and the second rotating shaft 6 at the same speed and in opposite directions through the motor 15, a tooth-retractable gear 11 is fixedly mounted on the shaft body of the first rotating shaft 2 at one end away from the first rotating wheel 3 and the shaft body of the second rotating shaft 6 at one end away from the second rotating wheel 7. A tooth groove 12 is opened on the surface of the tooth-retractable gear 11. The tooth groove 12 is a rectangular groove body. The tooth groove 12 is provided with a plurality of groups. The plurality of groups of tooth grooves 12 are distributed in a circle on the surface of the tooth-retractable gear 11. A tooth 13 is movably inserted in the tooth groove 12.

[0028] The surfaces of the first rotating shaft 2 and the second rotating shaft 6 are both sleeved and fixed with telescopic gears 11, and the teeth 13 can perform telescopic movement in the tooth groove 12 under the elastic action of the push spring 14, so that when the height of the telescopic gear 11 on the surface of the second rotating shaft 6 follows the slider 5 to be adjusted to any height, the teeth 13 on the surfaces of the two sets of telescopic gears 11 can still be meshed. Then, when the motor 15 drives the first rotating shaft 2 to rotate at a uniform speed in one direction, through the meshing action of the two sets of telescopic gears 11 on the surfaces of the first rotating shaft 2 and the second rotating shaft 6, the second rotating shaft 6 can perform a rotational movement at the same speed and in the opposite direction to that of the first rotating shaft 2.
[0029] Embodiment 4
[0030] On the basis of the third embodiment, in order to prevent the height of the slider 5 from being affected by the push spring 14 , the elastic force of the push spring 14 is much smaller than the elastic force of the height adjustment spring 8 .
[0031] The elastic force of the push spring 14 is much smaller than the elastic force of the height adjustment spring 8 , so that the direction of the resultant force on the surface of the slider 5 is the same as the direction of the thrust applied to the slider 5 by the height adjustment spring 8 , thereby preventing the height of the slider 5 from being affected by the push spring 14 .
[0032] In actual use, the second rotating wheel 7 is first pulled upward, and the pulling of the second rotating wheel 7 causes the slider 5 to slide upward in the sliding groove 4 through the second rotating shaft 6. The movement of the slider 5 compresses the height adjustment spring 8. Then, after one end of the wire harness is overlapped on the top of the first rotating wheel 3, the second rotating wheel 7 is released. Under the elastic action of the height adjustment spring 8, the second rotating wheel 7 is pressed against the top of the wire harness, so that the wire harness is clamped between the first rotating wheel 3 and the second rotating wheel 7. When the motor 15 drives the first rotating shaft 2 and the second rotating shaft 6 to rotate at the same speed in different directions, the first rotating wheel 3 and The second rotating wheel 7 also rotates in different directions at the same speed, so as to pull the wire harness. The wire harness production pulling device realizes the function of adjusting the distance between the first rotating wheel 3 and the second rotating wheel 7 by rotating the second rotating shaft 6 to the surface of the slider 5, sliding the slider 5 to the slide groove 4 opened on the surface of the frame 1, and fixing the height adjustment spring 8 between the slider 5 and the inner wall of the slide groove 4, so as to realize the function of adjusting the distance between the first rotating wheel 3 and the second rotating wheel 7, and ensure that the second rotating wheel 7 can be pressed against the top of the wire harness at any height, so as to achieve the pulling of wire harnesses of different diameters through the wire harness production pulling device. The guide rail 9 is provided on the surface of the groove body of the slide 4, and a guide plate 10 is fixed on the surface of the slider 5. The slider 5 is guided by the cooperation of the guide rail 9 and the guide plate 10, so that the slider 5 can only move in the vertical direction in the slide 4; the surfaces of the first rotating shaft 2 and the second rotating shaft 6 are both sleeved with a toothed retractable gear 11, and the teeth 13 can make a telescopic movement in the tooth groove 12 under the elastic action of the push spring 14, so that when the height of the toothed retractable gear 11 on the surface of the second rotating shaft 6 follows the slider 5 to be adjusted to any height, the two sets of toothed retractable gears The teeth 13 on the surface of the wheel 11 can still mesh. When the motor 15 drives the first rotating shaft 2 to rotate at a constant speed in one direction, the meshing action between the two sets of toothed retractable gears 11 on the surfaces of the first rotating shaft 2 and the second rotating shaft 6 can make the second rotating shaft 6 rotate in the opposite direction at the same speed as the first rotating shaft 2; the elastic force of the push spring 14 is much smaller than the elastic force of the height adjustment spring 8, so that the direction of the resultant force on the surface of the slider 5 is the same as the direction of the thrust applied to the slider 5 by the height adjustment spring 8, thereby preventing the height of the slider 5 from being affected by the push spring 14.
