Description

Technical Field

[0002] A wiring harness refers to a component that is formed by crimping contact terminals (connectors) punched out of copper materials with wires and cables, and then plastic-pressing an insulator or adding a metal shell on the outside to form a connecting circuit. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing and downstream application industries. Wire harnesses are widely used and can be used in automobiles, home appliances, computers and communications equipment, various electronic instruments and meters, etc.

[0003] In the process of processing and cutting, the electronic wire harness needs to be fixed with a positioning indicating device to prevent its position from shifting. The wire harness is cut by the positioning device. Since the wire harness is wound in a ring in the wire harness roll, when cutting, some wire harnesses cannot be shaped and straightened due to too many winding circles, resulting in defects in the cut surface when the wire harness is cut, reducing the working efficiency of the wire harness cutter. Moreover, after cutting, the next group of wire harnesses to be cut need to be manually placed in the cutting structure for cutting, which is inefficient. Summary of the invention

At this time, the drive shaft 10 is arranged at the leftmost end of the eccentric wheel 11, and the sleeve 12 drives the support plate 13 and the cutting piece 14 to move downward and continue to move to the right;

[0051] When gear one 48 continues to rotate 90 degrees counterclockwise, gear two 49 continues to rotate 90 degrees clockwise, and gear one 48 drives the drive shaft 10 on the first drive assembly 4 to continue to rotate 90 degrees, and the drive shaft 10 drives the eccentric wheel 11 to continue to rotate 90 degrees, and the eccentric wheel 11 drives the sleeve 12 to move upward and to the left at the same time. At this time, the drive shaft 10 is arranged at the lowermost end of the eccentric wheel 11, and the sleeve 12 drives the support plate 13 and the cutting piece 14 to move upward and to the left at the same time; gear two 49 drives the drive shaft 10 on the second drive assembly 5 to continue to rotate 90 degrees, and the drive shaft 10 drives the eccentric wheel 11 to continue to rotate 90 degrees, and the eccentric wheel 11 drives the sleeve 12 to move downward and to the left at the same time. At this time, the drive shaft 10 is arranged at the uppermost end of the eccentric wheel 11, and the sleeve 12 drives the support plate 13 and the cutting piece 14 to move downward and to the left at the same time;

[0052] When gear 1 48 rotates 90 degrees counterclockwise again, gear 2 49 rotates 90 degrees clockwise again, and gear 1 48 drives the drive shaft 10 on the first drive assembly 4 to rotate another 90 degrees, and the drive shaft 10 drives the eccentric wheel 11 to rotate another 90 degrees, and the eccentric wheel 11 drives the sleeve 12 to move downward and continue to move to the left.

[0053] In the left and right directions, the movement directions of the first drive assembly 4 and the second drive assembly 5 are synchronized, and in the up and down directions, the movement directions of the first drive assembly 4 and the second drive assembly 5 are opposite. Driven by the support plate 13, the adjustment assembly 6 and the shaping assembly 7 move toward or away from each other; when the drive shaft 10 is adjusted from the rightmost end to the leftmost end of the eccentric wheel 11; when they are about to approach each other, the cutting piece 14 starts to cut the wire harness, and at this time, the rubber pad 19 on the adjustment assembly 6 clamps the wire harness.

When the cutting is completed, the wire harness falls into the storage box 52. As the first drive assembly 4 and the second drive assembly 5 approach, the cutting pieces 14 are staggered. Then, when they move away from each other, the rubber pad 19 on the adjustment assembly 6 still clamps the wire harness, driving the wire harness to continue to move to the right, and the cutting piece 14 also moves to the right synchronously until the drive shaft 10 is set at the leftmost end of the eccentric wheel 11, the adjustment assembly 6 stops driving the wire harness, and the cutting piece 14 is adjusted from the staggered setting to the state of being about to cut;

[0054] At this time, driven by the support plate 13, the two groups of card plates move closer to each other and move along the limit groove 20 at the same time. The card plates drive the driving rod 24 to move closer to each other, the telescopic rod 23 is stretched, and the driving rod 24 drives the spring 26 and the shaping rod 27 to move closer to each other. The two groups of shaping rollers 28 are respectively arranged at the upper and lower ends of the wire harness. As the distance between the two approaches decreases first and then increases, the shaping rollers 28 perform shaping on the wire harness.

[0055] When the drive shaft 10 is adjusted from the leftmost end to the rightmost end of the eccentric wheel 11; the first drive assembly 4 and the second drive assembly 5 move away from each other first and then approach each other. During this process, the first drive assembly 4 and the second drive assembly 5 both move to the left, the cutting member 14 moves to the initial cutting position, the adjustment assembly 6 moves to the initial clamping position, and the telescopic rod 23 in the shaping assembly 7 is first compressed and then stretched, and returns to the initial shaping position, and the next round of processing begins;

[0056] When the support plate 13 moves to the right, the extrusion plate 31 is driven to move to the right, and the extrusion plate 31 drives the movable plate 30. The movable plate 30 moves along the slide groove toward the direction close to the mounting plate 29. The spring three 33 is compressed, and the gas in the folding bag 32 enters the vent hole 43, and enters the ventilation cavity one 44, the ventilation cavity two 45, and the ventilation cavity three 39 in sequence through the vent hole 43, and then enters the ventilation cavity four 40 through the vent pipe 41, and is discharged from the cleaning hole 42 to the through hole 38, so as to clean the wiring harness in the through hole 38. When the support plate 13 moves to the left, the spring three 33 drives the movable plate 30, and the folding bag 32 is unfolded. The external gas enters the folding bag 32 through the cleaning hole 42, the ventilation cavity four 40, the vent pipe 41, the ventilation cavity three 39, the ventilation cavity two 45, the ventilation cavity one 44 and the vent hole 43.
