Description

Technical Field

[0001] This utility model relates to the field of electronic wire production technology, and in particular to a cutting device for electronic wire production. Background Technology

[0002] Electronic wire harnesses, also known as wire harnesses, are systems that connect multiple wires, cables, or optical fibers together to transmit signals and power. After production, electronic wire harnesses are usually directly wound onto a take-up spool. At this time, the overall length of the wire harness is relatively long, and it is necessary to divide and package the wire harness according to the actual use requirements.

[0003] The existing wire harness cutting device has a relatively simple structure and cannot straighten the wire harness during cutting, resulting in inconsistent cable cutting lengths and affecting cutting accuracy. In order to address this technical problem, this application proposes a cutting device for electronic wire production. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cutting device for electronic wire production. During use, a drive motor drives a driven gear to rotate on a fixed ring, which in turn pushes a push rod to move a pressure block inside the fixed ring. This clamps and fixes the electronic wire harness passing through the center of the fixed ring, keeping it taut and ensuring that the wire harness has consistent specifications after cutting. During the cutting process, the support base also provides support for the electronic wire harness to prevent it from being pulled by the cutting blade and causing displacement, further ensuring the quality of wire harness cutting.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A cutting device for electronic wire production includes an operating table. Fixed seats are fixedly connected to the left and right sides of the top of the operating table. A transmission gear is provided on the outward side of the top of each fixed seat via a drive assembly. A fixed ring is fixedly connected to the top of each fixed seat. A pressure block is connected to the outward end of each fixed ring via a transmission component. Two first rotating seats are fixedly connected to the rear side of the top of the operating table. A rotating rod is rotatably connected to the outer wall of each first rotating seat. A cutting blade is fixedly connected to the front end of each rotating rod. A connecting rod is fixedly connected to the inward end of each cutting blade. A reset assembly is provided at the bottom end of each rotating rod.

[0007] Furthermore, the drive assembly includes drive motors fixedly connected to the top of the fixed base on the outward side, and each drive motor has a rotating shaft fixedly connected to its drive end, with transmission gears fixedly connected to the outer wall of each rotating shaft.

[0008] Furthermore, the inner end of each rotating shaft is rotatably connected to the outer end of the fixed ring, and a support seat is fixedly connected to the inner side of the top of each fixed seat.

[0009] Furthermore, the transmission component includes a limiting groove that is opened at the outer end of the fixed ring. Multiple limiting blocks are slidably connected to the inner wall of each limiting groove. A driven gear is fixedly connected to the outer end of each limiting block. Multiple sliding grooves are opened on the outer wall of the driven gear. Push rods are provided on the inner wall of each sliding groove.

[0010] Furthermore, the inner end of each push rod is fixedly connected to the outer end of the pressure block, the outer wall of each pressure block is slidably connected to the inner wall of the fixed ring, and the driven gear and the transmission gear are meshed.

[0011] Furthermore, the reset assembly includes a limiting block 1 fixedly connected to the bottom end of the rotating rod, a second rotating seat slidably connected to the outer wall of the limiting block 1, a slider rotatably connected to the outer wall of the second rotating seat, a compression spring fixedly connected to the bottom end of the slider, and a sleeve fixedly connected to the bottom end of the compression spring.

[0012] Furthermore, the outer walls of the sliders are all slidably connected to the inner walls of the sleeves, and the bottom ends of the sleeves are all fixedly connected to the top of the operating table.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, during use, the driven motor can drive the driven gear to rotate on the fixed ring, pushing the push rod to move the pressure block inside the fixed ring, thereby clamping and fixing the electronic wire harness passing through the center of the fixed ring, keeping it taut and ensuring that the wire harness specifications are consistent after cutting. During the cutting process, the support seat will also provide support for the electronic wire harness to prevent it from being pulled by the cutting blade and causing displacement, further ensuring the quality of wire harness cutting.

[0015] In this invention, by pulling down the connecting rod, the rotating rod can be rotated on the first rotating seat, thereby pulling the cutting blade downward to cut the electronic wire harness. After the cutting is completed, the slider will push the rotating rod upward under the action of the compression spring to reset it, thereby returning the cutting blade to its original position. The operation is very convenient. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-4 This utility model provides an embodiment of a cutting device for electronic wire production, comprising an operating table 1, with fixed seats 2 fixedly connected to both the left and right sides of the top of the operating table 1. Each fixed seat 2 has a transmission gear 5 mounted on its outer side via a drive assembly. The drive assembly includes a drive motor 3 fixedly connected to the outer side of the top of the fixed seat 2. Each drive motor 3 has a rotating shaft 4 fixedly connected to its drive end. Each rotating shaft 4 has a transmission gear 5 fixedly connected to its outer wall. The inner end of each rotating shaft 4 is rotatably connected to the outer end of a fixed ring 7. Each fixed seat 2 has a support base 15 fixedly connected to its inner side. Each end is fixedly connected to a fixing ring 7. The outer end of each fixing ring 7 is connected to a pressure block 20 via a transmission component. The transmission component includes a limiting groove 18 located at the outer end of each fixing ring 7. Multiple limiting blocks 21 are slidably connected to the inner wall of each limiting groove 18. A driven gear 6 is fixedly connected to the outer end of each limiting block 21. Multiple sliding grooves 17 are provided on the outer wall of the driven gear 6. Push rods 19 are provided on the inner wall of each sliding groove 17. The inner end of each push rod 19 is fixedly connected to the outer end of each pressure block 20. The outer wall of each pressure block 20 is slidably connected to the inner wall of the fixing ring 7. The driven gear 6 and the transmission gear 5 are meshed.

[0024] Specifically, during use, the drive motor 3 drives the rotating shaft 4 to rotate, causing the transmission gear 5 to drive the driven gear 6 to rotate on the fixed ring 7. The sliding groove 17 on the driven gear 6 can push the push rod 19 to move the pressure block 20 inside the fixed ring 7, thereby clamping and fixing the electronic wire harness passing through the center of the fixed ring 7, keeping it in a taut state to ensure that the wire harness specifications are consistent after cutting. The operation is simple and the fixation is stable. During the cutting process, the support seat 15 will also provide support for the electronic wire harness to prevent it from being pulled by the cutting blade 8 and causing displacement, further ensuring the quality of wire harness cutting.

[0025] Two first rotating seats 10 are fixedly connected to the rear side of the top of the operating table 1. Rotating rods 11 are rotatably connected to the outer walls of the first rotating seats 10. Cutting blades 8 are fixedly connected to the front ends of the rotating rods 11. A connecting rod 9 is fixedly connected to the inward end of the cutting blades 8. A reset assembly is provided at the bottom of the rotating rods 11. The reset assembly includes a limiting block 12 fixedly connected to the bottom of the rotating rods 11. A second rotating seat 13 is slidably connected to the outer walls of the limiting block 12. A slider 14 is rotatably connected to the outer walls of the second rotating seat 13. A compression spring 22 is fixedly connected to the bottom of the slider 14. A sleeve 16 is fixedly connected to the bottom of the compression spring 22. The outer walls of the slider 14 are slidably connected to the inner walls of the sleeve 16. The bottom of the sleeve 16 is fixedly connected to the top of the operating table 1.

[0026] Specifically, by pulling down the connecting rod 9, the rotating rod 11 can rotate on the first rotating seat 10, thereby pulling the cutting blade 8 downward to cut the electronic wire harness. After the cutting is completed, the slider 14 will push the rotating rod 11 upward under the elastic force of the compression spring 22 to reset it, thereby returning the cutting blade 8 to its original position. The operation is very convenient. The limiting block 12 set at the bottom of the rotating rod 11 is used to guide the second rotating seat 13 and limit its movement direction. The second rotating seat 13 is used to ensure that the rotating rod 11 can press down the slider 14 normally when rotating, so that it slides on the inner wall of the sleeve 16.

[0027] Working principle: In actual use, the user can pass the electronic wire harness to be cut through the two fixed rings 7 in sequence. Then, the drive motor 3 is started to drive the rotating shaft 4 to rotate, which drives the transmission gear 5 to rotate, thereby causing the driven gear 6 to rotate. Through the sliding groove 17 opened on the driven gear 6, the push rod 19 is pushed to move. Under the restriction of the fixed rings 7, the pressure block 20 is driven by the push rod 19 to move towards the center of the fixed rings 7, clamping and fixing the surface of the wire harness, so that the wire harness can be kept in a taut state during cutting. Then, the user can pull down the connecting rod 9, so that the rotating rod 11 rotates on the first rotating seat 10, and the slider 14 compresses the compression spring 22 inside the sleeve 16, causing the cutting blade 8 to move downward to cut the wire harness. During the downward cutting process, the support seat 15 can provide support for the wire harness being cut, preventing the wire harness from being pulled downward by the cutting blade 8 and affecting the cutting. After the cutting is completed, the connecting rod 9 is released. At this time, the compression spring 22 inside the sleeve 16 will release its elasticity to lift the slider 14, push the rotating rod 11 to reset, and make the cutting blade 8 automatically lift and reset.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
