Description

Technical Field

[0001] This utility model relates to the field of coil cutting technology, and in particular to a precise cutting device for nanocrystalline coils. Background Technology

[0002] In the production and manufacturing of nanocrystalline coils, the cutting accuracy of the lead wires directly affects the assembly quality and electrical performance of the coils. As a key component connecting the coils to external circuits, the lead wires need to be precisely cut to the same length to ensure the consistency of subsequent welding, insertion and other processes.

[0003] Currently available cutting devices often lack effective positioning and fixing mechanisms when cutting nanocrystalline coil leads. Since nanocrystalline coil leads are typically thin and flexible, without reliable fixing during the cutting process, the external force applied by the cutting tool can easily cause the leads to slip or deform. This slippage and deformation can lead to deviations in the cutting position, resulting in inconsistent lead lengths after cutting, which seriously affects the cutting accuracy. Therefore, we propose a precise cutting device for nanocrystalline coils. Utility Model Content

This device can solve the problem that common cutting devices on the market often lack an effective positioning and fixing mechanism when cutting nanocrystalline coil leads. Since the leads of nanocrystalline coils are usually thin and soft, if the leads are not reliably fixed during the cutting process, the external force applied by the cutting tool can easily cause the leads to slip or deform. This slip and deformation will cause deviations in the cutting position, resulting in inconsistent lead lengths after cutting, which seriously affects the cutting accuracy.

[0009] Preferably, the lead positioning structure further includes a sliding disk, a connecting rod, a spring, a connecting plate, and a plug rod. The sliding disk is slidably connected inside the limiting groove. The connecting rod is fixedly connected to one side of the sliding disk. The end of the connecting rod away from the sliding disk extends slidably to the outside of the limiting groove and is fixedly connected to the connecting plate. The plug rod is fixedly connected to the side of the connecting plate near the connecting rod. The plug rod is inserted into the inside of the insertion hole. The spring is sleeved on the outer surface of the connecting rod.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a nanocrystalline coil wire cutting precision cutting device, comprising:

[0027] The coil cutting base 1 has a sliding frame 6 fixedly connected to its top. The top of the coil cutting base 1 is provided with a lead wire cutting structure, and the sliding frame 6 has a "U" shaped structure.

[0028] A lead wire positioning structure is located on the coil cutting base 1.

[0029] The lead wire positioning structure includes an electric telescopic rod 7, a movable platform 8, two fixed plates 13, and a rotating pressing frame 9. The electric telescopic rod 7 is fixedly installed on one side of the sliding frame 6. The telescopic end of the electric telescopic rod 7 extends slidably into the interior of the sliding frame 6 and is fixedly connected to the movable platform 8. The movable platform 8 is slidably connected inside the sliding frame 6. The two fixed plates 13 are fixedly connected to the top of the movable platform 8. The rotating pressing frame 9 is rotatably connected to the opposite surfaces of the two fixed plates 13. An insertion hole 15 is provided on one side of the rotating pressing frame 9. A limit groove 17 is provided on one side of the movable platform 8. Four lead wire positioning seats 20 are fixedly connected to the top of the movable platform 8.

[0030] The lead wire positioning structure also includes a sliding disk 16, a connecting rod 18, a spring 19, a connecting plate 12, and a plug rod 14. The sliding disk 16 is slidably connected inside the limiting groove 17. The connecting rod 18 is fixedly connected to one side of the sliding disk 16. The end of the connecting rod 18 away from the sliding disk 16 extends slidably to the outside of the limiting groove 17 and is fixedly connected to the connecting plate 12. The plug rod 14 is fixedly connected to the side of the connecting plate 12 near the connecting rod 18. The plug rod 14 is inserted into the inside of the insertion hole 15. The spring 19 is sleeved on the outer surface of the connecting rod 18.

[0031] One end of the spring 19 is fixedly connected to the sliding disk 16, and the end of the spring 19 away from the sliding disk 16 is fixedly connected to the inside of the limiting slide groove 17.

[0032] The lead wire cutting structure includes a fixed frame 2, an electric telescopic rod 3, a tool mounting bracket 4, and a cutting blade 5. The fixed frame 2 is fixedly connected to the top of the coil cutting base 1. The electric telescopic rod 3 is fixedly installed on the top of the fixed frame 2. The telescopic end of the electric telescopic rod 3 slides into the interior of the fixed frame 2 and is fixedly connected to the tool mounting bracket 4. The cutting blade 5 is fixedly installed inside the tool mounting bracket 4 by bolts. The top of the moving table 8 has multiple threaded holes 10. The moving table 8 is provided with six positioning posts 11. The bottom ends of the six positioning posts 11 are all connected to the internal threads of the corresponding threaded holes 10.

[0033] Furthermore, when using this device, depending on the specifications of the nanocrystalline coil, the positioning post 11 can be installed in the appropriate threaded hole 10, allowing the nanocrystalline coil to be placed outside multiple positioning posts 11, thus facilitating the positioning of the nanocrystalline coil. Subsequently, after placing the lead wire of the nanocrystalline coil on the lead wire positioning seat 20, the rotating pressing frame 9 is rotated, and the user pulls the connecting plate 12. The connecting plate 12 will simultaneously drive the insertion rod 14 and the connecting rod 18 to move, causing the connecting rod 18 to drive the sliding plate 16 to compress the spring 19. When the rotating pressing frame 9 rotates to a horizontal position and squeezes the lead wire, the connecting plate 12 is released. Under the action of the spring 19, the connecting plate 12 drives the insertion rod 14 to move towards the rotating pressing frame 9, so that the insertion rod 14 is inserted into the insertion hole 15 opened on one side of the rotating pressing frame 9, thereby fixing the position of the rotating pressing frame 9 and achieving precise positioning of the lead wire.

[0034] Start the second electric telescopic rod 7. The telescopic end of the second electric telescopic rod 7 extends and retracts, causing the moving table 8 to slide within the sliding frame 6. This adjusts the moving table 8 to move below the cutting blade 5, so that the cutting blade 5 can be positioned at the notch between the four lead wire positioning seats 20. Then, start the first electric telescopic rod 3. The first electric telescopic rod 3 drives the tool mounting frame 4 and the cutting blade 5 to move downward. The cutting blade 5 contacts the lead wire and cuts the lead wire, completing the cutting of the nanocrystalline coil lead wire.

[0035] By rotating the pressing frame 9 in conjunction with the insertion rod 14 and the insertion hole 15, the pressing frame 9 can fix the vertical position of the lead wire. At the same time, the lead wire positioning seat 20 can prevent the lead wire from shifting horizontally, and the positioning post 11 can be flexibly installed according to different specifications of coils to further assist in positioning, ensuring the accuracy of lead wire positioning, thereby improving the cutting accuracy, ensuring that the length of the cut lead wire meets the requirements, and improving product quality.
