Description

Technical Field

[0001] The invention relates to the field of spring wire harness processing devices, and in particular to a processing device and method for extremely small spring wire harnesses. Background Art

[0002] Spring wire, also known as slingshot wire and spiral wire, is a device connection wire that uses scalability to work. It is generally made of TPU cable. It is used to control the power connection of the movement of movable equipment. It can rebound quickly in a short time. It is widely used in movable equipment such as automobiles, machines, and instruments. The ultra-small spring wire harness is a small-sized spiral wire. During the processing of the spring wire harness, the wire harness needs to be wound on the rod into a spiral shape and fixed. At the same time, a wire feeding mechanism is required to cooperate with the wire feeding.

[0003] The existing spring wire harness processing on the market generally uses a wire feeding mechanism to cooperate with a single rod driven to wind and fix the wire harness, so only one wire harness can be spirally wound at a time, so the overall efficiency of the device is low and cannot meet the needs of users.

A sliding rod 31 is provided on the surface of the outer ring 25 in the structure. The sliding rod 31 is slidably connected to the outer ring 25 in the structure. The number of the sliding rods 31 in the structure is the same as the number of the connecting rods 27. A guide hole 32 is provided on one side of the sliding rod 31 in the structure. The guide hole 32 in the structure is provided on the surface of the outer ring 25. The top of the sliding rod 31 in the structure is threadedly connected with a limiting bolt 33. The bottom of the sliding rod 31 in the structure is fixedly connected with a second fixing frame. An extrusion spring 34 is sleeved on the outside of the sliding rod 31 in the structure. One end of the extrusion spring 34 in the structure abuts against the inner wall of the outer ring 25. The other end of the extrusion spring 34 in the structure abuts against the second fixing frame. A second guide wheel 35 is rotatably connected to the inner side of the second fixing frame in the structure. The second guide wheel 35 in the structure matches the first guide wheel 30.

[0041] Multiple wire harnesses can be simultaneously passed through the base 1 through the multiple conveying holes 3, and then the wire harnesses are passed between the first guide wheel 30 and the second guide wheel 35, so that the wire harnesses can be limited and fixed, and finally the wire harnesses are passed through the guide roller guide hole 32, thereby completing the limiting operation of the wire harnesses.

[0042] Further, in the above technical scheme, the number of winding rods 13 in the structure is the same as the number of driven gears 17, one end of the winding rod 13 in the structure is fixedly connected with a first threaded rod 36, the outer side of the first threaded rod 36 in the structure is threadedly connected with a fixing nut 37, one end of the first threaded rod 36 in the structure is fixedly connected with an extension block 38, and the extension block 38 in the structure matches the positioning groove 24, a threaded groove 39 is provided at the other end of the winding rod 13 in the structure, a slide groove 40 is provided at one end of the threaded groove 39 in the structure, a second threaded rod 41 is threadedly connected inside the threaded groove 39 in the structure, one end of the second threaded rod 41 in the structure extends into the slide groove 40, one end of the second threaded rod 41 in the structure is fixedly connected with a limiting plate 42, the other end of the second threaded rod 41 in the structure is fixedly connected with a positioning block 43, the limiting plate 42 in the structure is slidably connected to the slide groove 40, a slot 44 is provided on one side of the positioning block 43 in the structure, and the slot 44 in the structure matches the positioning rod 18;

[0043] After the positioning plate 8 and the driving mechanism 10 are moved upward, a plurality of winding rods 13 can be placed between a plurality of driving gears 14 and the rotating gear 23. The winding rod 13 can be vertically positioned by inserting the extension block 38 into the positioning slot 24. Then, one end of the wire harness is wound around the first threaded rod 36. Then, the wire harness can be fixed to one end of the winding rod 13 by rotating the fixing nut 37. Then, the positioning plate 8 and the driving mechanism 10 are moved downward so that the positioning rod 18 is inserted into the slot 44. At this time, the winding rod 13 can be driven to rotate by the rotating driven gear 17, so that the rotating winding rod 13 can wind the wire harness. At the same time, the driving rod 15 will also rotate. Because the inner ring 26 is threadedly connected to the driving rod 15, the wire feeding mechanism 11 can move outside the driving rod 15. Thus, multiple strands of wire harness can be uniformly delivered to the surfaces of the plurality of winding rods 13 at the same time through the wire feeding mechanism 11, and then the wire harness is wound into a spiral shape on the surface of the winding rod 13.

[0044] When a wiring harness is wound around the surface of the second threaded rod 41, the stepper motor 9 can be controlled to rotate in the reverse direction. At this time, the driven gear 17 will drive the winding rod 13 to rotate in the reverse direction. However, because the rotating gear 23 cannot rotate, the reversely rotating driven gear 17 will drive the positioning block 43 and the second threaded rod 41 to rotate through the positioning rod 18, thereby extending the second threaded rod 41 into the slide groove 40, and at the same time driving the positioning block 43 to approach the winding rod 13 and squeeze and fix the wiring harness. Through the above operation, the wiring harnesses on the surfaces of multiple winding rods 13 can be fixed at the same time.

[0046] After the wire harness is wound on the surface of the winding rod 13, the positioning plate 8 and the driving mechanism 10 are moved upward, and the wire feeding mechanism 11 threadedly fixed to the driving rod 15 is driven to move upward, so that the wire harness between the wire feeding mechanism 11 and the winding rod 13 moves upward a certain distance. When the driving rod 15 rotates, the protrusion 46 and the rotating ring 45 are driven to rotate through the driving groove 16, and the cutting blade 48 rotating on the surface of the rotating ring 45 cuts off multiple strands of wire harness at the same time, and the winding rod 13 with the wire harness wound can be taken out.

[0047] Furthermore, in the above technical solution, the surfaces of the first guide wheel 30 and the second guide wheel 35 in the structure are both provided with an annular guide groove, and the cross-sectional shape of the guide groove in the structure is set to be an arc;

[0048] The wire harness can be limited by providing the guide groove, thereby preventing the wire harness from being separated between the first guide wheel 30 and the second guide wheel 35 .

[0049] Further, in the above technical solution, one side of the cutting blade 48 in the structure is set to be arc-shaped, the number of the cutting blades 48 in the structure is set to be multiple, and the multiple cutting blades 48 are distributed around the center of the rotating ring 45;

[0050] By making one side of the cutting blade 48 arc-shaped, it is possible to make it easier to cut the wire harness, thereby making it easier to cut the wire harness.

[0051] The present invention also provides a method for processing a very small spring wire harness, including the processing device of the very small spring wire harness, comprising the following steps:

[0052] S1. Preparation: The electric push rod 12 is used to drive the positioning plate 8 to move upward, and multiple winding rods 13 are respectively fixed between multiple groups of driven gears 17 and driving gears 14. At the same time, multiple wire harnesses are passed through the wire feeding mechanism 11 and the wire harnesses are respectively fixed to one end of the winding rod 13.

[0053] S2, wire harness winding, the stepper motor 9 and the driving mechanism 10 simultaneously drive the driving rod 15 and the winding rod 13 to rotate, so that the winding rod 13 can rotate to spirally wind the wire harness on the surface of the winding rod 13, and the wire feeding mechanism 11 will move with the winding of the wire harness.

[0054] S3, the wire harness is taken out. The positioning plate 8 can be driven upward by starting the electric push rod 12, and the rotating cutting blade 48 can cut off the connected wire harness. At this time, the winding rod 13 with the wire harness can be taken out.
