Description

Technical Field

[0001] The utility model relates to the technical field of wire harness stretching, in particular to a novel stretching device for wire harness processing. Background Art

[0002] A wiring harness refers to a linear material. Many wiring harness materials in life are ductile, so some wiring harnesses need to be stretched and extended.

[0003] After searching, the utility model patent with patent number CN219568180U discloses "a stretching device for processing carbon fiber bundles". The stretching device for processing carbon fiber bundles is provided with a processing table, a fixed plate, a servo motor, a winding drum, a second pull rope, a second rubber block and a blade. When in use, the transmission rod can reel in the first pull rope and release the second pull rope at the same time. The first pull rope pulls the left side of the fixed plate to rotate downward, so that the first rubber block on the fixed plate cooperates with the second rubber block to press the carbon fiber bundle, thereby ensuring the stretching effect of carbon fiber bundles of different sizes. When the stretching is completed and needs to be cut off, the blade on the fixed plate can also cut off the carbon fiber bundle, thereby further improving the processing efficiency of the carbon fiber bundle.

[0004] The device fixes the carbon fiber by pressing, but when the carbon fiber is stretched, it will constantly pass between the two sets of rubber blocks, so it is easy to wear out the rubber blocks, resulting in the inability to press the carbon fiber normally, affecting the normal stretching of the carbon fiber by the device.

[0005] Therefore, it is necessary to provide a new type of wire harness processing stretching device to solve the above technical problems. Utility Model Content

When the rotation speed of the second rotating rod 7 is greater than the rotation speed of the first rotating rod 3, a pulling force will be generated on the carbon fiber. A bottom block 10 is fixedly connected to the upper end of the workbench 1, a support rod 11 is fixedly connected to the upper end of the bottom block 10, a top plate 12 is fixedly connected to the upper end of the support rod 11, a telescopic cylinder 13 is arranged on the upper end of the top plate 12, a lifting plate 14 is fixedly connected to the output end of the telescopic cylinder 13, and a groove matching the output end of the telescopic cylinder 13 is opened on the upper end of the top plate 12.

[0020] A first slide bar 15 is slidably connected to the bottom of the lifting plate 14, a first limit plate 16 is fixedly connected to the upper end of the first slide bar 15, a pressing plate 17 is fixedly connected to the bottom of the first slide bar 15, and a rubber pad 18 is fixedly connected to the bottom of the pressing plate 17. The rubber pad 18 can be provided to protect the carbon fiber to prevent damage to the carbon fiber when pressed.

[0021] A first spring 19 is sleeved on the side surface of the first slide bar 15 . The first spring 19 is located between the lifting plate 14 and the pressing plate 17 . A second slide bar 20 is slidably connected to the bottom of the lifting plate 14 .

[0022] A second limiting plate 21 is fixedly connected to the upper end of the second slide bar 20, and a mounting plate 22 is fixedly connected to the bottom of the second slide bar 20. A blade 23 is arranged at the bottom of the mounting plate 22, and the blade 23 is fixed to the bottom of the mounting plate 22 by a screw 24. A second spring 25 is sleeved on the side surface of the second slide bar 20, and the second spring 25 is located between the lifting plate 14 and the mounting plate 22. The blade 23 can be easily replaced by setting the screw 24.

[0023] The working principle of a novel wire harness processing stretching device provided by the utility model is as follows:

[0024] Step 1: When in use, wind the carbon fiber around the side of the pay-off drum 5, then pass one end of the carbon fiber through the bottom block 10 and the lifting plate 14, and then fix it on the side of the take-up drum 9. The take-up drum 9 can be wound up by rotating the second rotating rod 7 driven by the second motor 8. At this time, the pay-off drum 5 can be rotated to release the carbon fiber by driving the first rotating rod 3 to rotate by the first motor 4. By controlling the rotation speed of the second rotating rod 7 to be greater than the rotation speed of the first rotating rod 3, the carbon fiber can be stretched and extended.

[0025] Step 2: When cutting is required, the telescopic cylinder 13 drives the lifting plate 14 to move downward. At this time, the rubber pad 18 will first press and fix the carbon fiber, and then the blade 23 will continue to descend to cut the carbon fiber. The pressing and fixing of the rubber pad 18 can facilitate the fixing of the cut end of the carbon fiber, thereby preventing the carbon fiber from becoming loose.

[0026] Compared with the related art, the novel wire harness processing stretching device provided by the utility model has the following beneficial effects:

[0027] The carbon fiber is wound around the side of the pay-off drum 5, and then one end of the carbon fiber is passed between the bottom block 10 and the lifting plate 14, and then fixed on the side of the take-up drum 9. The second motor 8 drives the second rotating rod 7 to rotate so that the take-up drum 9 can reel the carbon fiber. At this time, the first motor 4 drives the first rotating rod 3 to rotate so that the pay-off drum 5 can rotate to release the carbon fiber. By controlling the rotation speed of the second rotating rod 7 to be greater than the rotation speed of the first rotating rod 3, the carbon fiber can be stretched and extended. The pressing mechanism is omitted through this mechanism, thereby avoiding the wear of the pressing mechanism by the carbon fiber, the operation is relatively stable, and it is very convenient to use. When cutting is required, the lifting plate 14 is driven downward by the telescopic cylinder 13. At this time, the rubber pad 18 will first press and fix the carbon fiber, and then the blade 23 continues to descend to cut the carbon fiber. The pressing and fixing of the rubber pad 18 can facilitate the fixation of the cut end of the carbon fiber, thereby preventing the carbon fiber from being loose. The carbon fiber can be cut and fixed through this mechanism, which is very convenient to use.
