A positioning device for winding high-efficiency nanocrystalline iron core

Abstract

This utility model discloses a positioning device for winding high-efficiency nanocrystalline iron cores, belonging to the technical field of positioning devices. The utility model includes a placement platform, with a base plate fixedly connected to the inner wall of the platform. A first sliding groove is formed on the top of the platform, and a controller is fixedly connected to the outer wall. A placement mechanism is provided inside the platform, and a clamping mechanism is provided on the placement mechanism. This utility model uses a servo motor to drive a worm gear to rotate clockwise, which in turn drives a worm wheel to rotate clockwise. The worm wheel then drives a threaded rod to rotate clockwise. The clockwise rotation of the threaded rod causes a threaded slider to rise along the threaded rod, thereby causing the bottom end of a connecting rod to rise. The top end of the connecting rod can push a first slider to move along a first sliding rod away from the center of the placement platform. The first slider drives a fixed rod, which carries placement seats, thus allowing adjustment of the distance between the placement seats to accommodate different types of annular nanocrystalline iron cores.

Description

Technical Field

[0001] This utility model belongs to the technical field of positioning devices, and in particular relates to a positioning device for winding high-efficiency nanocrystalline iron cores. Background Technology

[0002] Nanocrystalline cores are iron cores made of nanoscale iron-based alloy materials, commonly used in power electronics, transformers, inductors, magnetic sensors, and other devices. Compared to traditional iron-silicon alloys and other magnetic materials, nanocrystalline cores offer significant advantages, especially in high-frequency applications. Nanocrystalline cores typically come in various shapes, including toroidal, U-shaped, and E-shaped. A coil is usually formed by winding wires around the nanocrystalline core; this process is commonly used to manufacture electrical components such as inductors, transformers, and induction coils.

[0003] When winding wires around a toroidal nanocrystalline iron core, it is usually necessary to place the toroidal nanocrystalline iron core on a mounting frame and then fix it with a clamp. However, a large mounting frame will obstruct the winding, while a small mounting frame will make it difficult to place a large diameter toroidal nanocrystalline iron core, which makes it quite troublesome to place and fix the toroidal nanocrystalline iron core. Summary of the Invention

[0004] The purpose of this invention is to provide a positioning device for winding high-efficiency nanocrystalline iron cores. By driving the worm gear to rotate clockwise through a servo motor, the distance between the placement seats is adjusted. This solves the problem that a large placement frame will obstruct the winding, while a small placement frame will make it difficult to place large-diameter annular nanocrystalline iron cores, making it troublesome to place and fix the annular nanocrystalline iron cores.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a positioning device for winding high-efficiency nanocrystalline iron core, including a placement platform, a base plate fixedly connected to the inner wall of the placement platform, a first sliding groove opened on the top of the placement platform, a controller fixedly connected to the outer wall of the placement platform, a placement mechanism provided inside the placement platform, and a clamping mechanism provided on the placement mechanism.

[0007] The placement mechanism includes a servo motor, the output end of which is fixedly connected to a worm gear via a coupling. A threaded rod is rotatably connected to the top of the base plate. A worm wheel is fixedly connected to the outer wall of the threaded rod. A threaded slider is threadedly connected to the outer wall of the threaded rod. A connecting rod is rotatably connected to the outer wall of the threaded slider. A first sliding rod is fixedly connected inside the first sliding groove. A first slider is slidably connected to the outer wall of the first sliding rod. A fixing rod is fixedly connected to the end of the first slider away from the connecting rod. A placement seat is fixedly connected to the end of the fixing rod away from the first slider.

[0008] Furthermore, the bottom of the servo motor is fixedly connected to the base plate on the top, and the end of the threaded rod away from the base plate is fixedly connected to the inner top wall of the placement platform, and the worm gear meshes with the worm.

[0009] Furthermore, the first slider is slidably connected inside the first groove, and the end of the connecting rod away from the threaded slider is rotatably connected to the bottom of the first slider.

[0010] Furthermore, the clamping mechanism includes a push rod, the outer wall of which is slidably connected to the inside of the placement seat, and a retaining ring is fixedly connected to one end of the push rod away from the center of the placement platform.

[0011] Furthermore, a spring is fixedly connected to the side of the retaining ring near the push rod, the push rod is located inside the spring, and the end of the spring away from the retaining ring is fixedly connected to the placement seat.

[0012] Furthermore, a limiting plate is fixedly connected to the end of the push rod away from the retaining ring, the side of the limiting plate near the push rod contacts the outer wall of the placement seat, and a pull rod is rotatably connected to the top of the limiting plate.

[0013] Furthermore, a second sliding groove is provided on the placement seat, a second sliding rod is fixedly connected inside the second sliding groove, and a second slider is slidably connected to the outer wall of the second sliding rod.

[0014] Furthermore, the second slider is slidably connected inside the second groove, the end of the pull rod away from the limiting plate is rotatably connected to the second slider, and a clamping plate is fixedly connected to the side of the second slider away from the pull rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses a servo motor to drive a worm gear to rotate clockwise, which in turn drives a worm wheel to rotate clockwise. The worm wheel then drives a threaded rod to rotate clockwise. The clockwise rotation of the threaded rod causes the threaded slider to rise along the threaded rod, thereby causing the bottom end of the connecting rod to rise. The top end of the connecting rod can push the first slider to move along the first slide bar away from the center of the placement platform. The first slider drives a fixed rod, which carries a placement seat. This allows for adjustment of the distance between the placement seats to accommodate different types of annular nanocrystalline iron cores. At the same time, it can reduce the size of the support and avoid obstructing the winding.

[0017] 2. In this invention, the placement seat continues to move away from the center of the placement platform, causing the inner wall of the annular nanocrystalline iron core to contact the retaining ring. As the placement seat continues to move, the spring is compressed, and the spring's reaction force allows the retaining ring to adhere to the annular nanocrystalline iron core. The push rod moves relative to the placement seat towards the center of the placement platform. At this time, the push rod drives the limiting plate to move, and the limiting plate drives the bottom end of the pull rod to move. The bottom end of the pull rod pulls the second slider to move downward along the second slide rod. The second slider drives the clamping plate to move, causing the clamping plate to contact the top of the annular nanocrystalline iron core. At this time, the clamping plate cannot move downward, and the retaining ring is tightly attached to the inner wall of the annular nanocrystalline iron core, which can effectively fix the annular nanocrystalline iron core and prevent the annular nanocrystalline iron core from moving during the winding process.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] 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.

[0028] Please see Figure 1-5 As shown, this utility model is a positioning device for winding high-efficiency nanocrystalline iron core, including a placement platform 1, a base plate 11 fixedly connected to the inner wall of the placement platform 1, a first sliding groove 12 opened on the top of the placement platform 1, a controller 13 fixedly connected to the outer wall of the placement platform 1, a servo motor 201 is started clockwise by the controller 13, a placement mechanism 2 is provided inside the placement platform 1, and a clamping mechanism 3 is provided on the placement mechanism 2.

[0029] The placement mechanism 2 includes a servo motor 201. A worm gear 202 is fixedly connected to the output end of the servo motor 201 via a coupling. The servo motor 201 drives the worm gear 202 to rotate clockwise, which in turn drives the worm wheel 204 to rotate clockwise. A threaded rod 203 is rotatably connected to the top of the base plate 11. A worm wheel 204 is fixedly connected to the outer wall of the threaded rod 203, which drives the threaded rod 203 to rotate clockwise. A threaded slider 205 is threadedly connected to the outer wall of the threaded rod 203. Clockwise rotation of the threaded rod 203 causes the threaded slider 205 to rise along the threaded rod 203, thereby causing the bottom end of the connecting rod 206 to rise. The connecting rod 206 is rotatably connected to the outer wall of the threaded slider 205, and the top end of the connecting rod 206 can push the first slider 208 to move away from the center of the placement platform 1 along the first slide bar 207. The first slide bar 207 is fixedly connected inside the first slide groove 12. The first slider 208 is slidably connected to the outer wall of the first slide rod 207. The first slider 208 drives the fixed rod 209. The end of the first slider 208 away from the connecting rod 206 is fixedly connected to the fixed rod 209. The end of the fixed rod 209 away from the first slider 208 is fixedly connected to the placement seat 210. The fixed rod 209 carries the placement seat 210, so that the distance between the placement seats 210 can be adjusted to accommodate different annular nanocrystalline iron cores. At the same time, it can reduce the volume of the bracket and avoid obstructing the winding. The bottom of the servo motor 201 is fixedly connected to the base plate 11 at the top. The end of the threaded rod 203 away from the base plate 11 is fixedly connected to the inner top wall of the placement platform 1. The worm gear 204 meshes with the worm 202. The first slider 208 is slidably connected inside the first slide groove 12. The end of the connecting rod 206 away from the threaded slider 205 is rotatably connected to the bottom of the first slider 208.

[0030] The clamping mechanism 3 includes a push rod 301, the outer wall of which is slidably connected to the inside of the placement seat 210. At this time, the placement seat 210 continues to move away from the center of the placement stage 1, causing the inner wall of the annular nanocrystalline iron core to contact the retaining ring 302. As the placement seat 210 continues to move, the spring 303 is compressed. The end of the push rod 301 away from the center of the placement stage 1 is fixedly connected to the retaining ring 302, and the side of the retaining ring 302 closest to the push rod 301 is fixedly connected to the spring 303. 03 The reaction force enables the retaining ring 302 to fit against the annular nanocrystalline iron core. The push rod 301 is located inside the spring 303. The push rod 301 will move relative to the placement seat 210 towards the center of the placement platform 1. The end of the spring 303 away from the retaining ring 302 is fixedly connected to the placement seat 210. The end of the push rod 301 away from the retaining ring 302 is fixedly connected to the limiting plate 304. At this time, the push rod 301 will drive the limiting plate 304 to move. The side of the limiting plate 304 near the push rod 301 is connected to the placement seat 210. The outer wall contacts the limit plate 304, which drives the bottom end of the pull rod 305 to move. The top of the limit plate 304 is rotatably connected to the pull rod 305, and the bottom end of the pull rod 305 pulls the second slider 308 to move downward along the second slide rod 307. The placement seat 210 has a second slide groove 306, and the second slide rod 307 is fixedly connected inside the second slide groove 306. The second slider 308 is slidably connected to the outer wall of the second slide rod 307. The second slider 308 is slidably connected inside the second slide groove 306. The pull rod 305 is far from the limit plate 304. One end of the limiting plate 304 is rotatably connected to the second slider 308. The side of the second slider 308 away from the pull rod 305 is fixedly connected to the clamping plate 309. The second slider 308 drives the clamping plate 309 to move, so that the clamping plate 309 contacts the top of the annular nanocrystalline iron core. At this time, the clamping plate 309 cannot move downward, and the retaining ring 302 is also tightly attached to the inner wall of the annular nanocrystalline iron core, which can effectively fix the annular nanocrystalline iron core and prevent the annular nanocrystalline iron core from moving during the winding process.

[0031] One specific application of this embodiment is:

[0032] In use, the servo motor 201 is started clockwise by the controller 13. The servo motor 201 drives the worm gear 202 to rotate clockwise, which in turn drives the worm wheel 204 to rotate clockwise. The worm wheel 204 drives the threaded rod 203 to rotate clockwise. The clockwise rotation of the threaded rod 203 causes the threaded slider 205 to rise along the threaded rod 203, thereby causing the bottom end of the connecting rod 206 to rise. The top end of the connecting rod 206 can push the first slider 208 to move along the first slide bar 207 away from the center of the placement platform 1. The first slider 208 drives the fixed rod 209, which carries the placement seat 210. This allows adjustment of the distance between the placement seats 210 to accommodate different types of annular nanocrystalline iron cores, while also reducing the size of the support and avoiding obstruction of the winding. After adjusting the placement seat 210, the servo motor 201 is stopped, and then the annular nanocrystalline iron core is placed on the placement seat 210, with the side of the servo motor 201 closest to the placement platform 1 positioned on the annular nanocrystalline iron core. Inside the ring, the servo motor 201 is started clockwise. At this time, the placement seat 210 will continue to move away from the center of the placement platform 1, so that the inner wall of the annular nanocrystalline iron core contacts the retaining ring 302. As the placement seat 210 continues to move, the spring 303 will be compressed, and the reaction force of the spring 303 can make the retaining ring 302 fit with the annular nanocrystalline iron core. The push rod 301 will move relative to the placement seat 210 towards the center of the placement platform 1. At this time, the push rod 301 will drive the limiting plate 304. The movement of the limiting plate 304 causes the bottom end of the pull rod 305 to move, and the bottom end of the pull rod 305 will pull the second slider 308 to move downward along the second slide rod 307. The second slider 308 causes the clamping plate 309 to move, so that the clamping plate 309 contacts the top of the annular nanocrystalline iron core. At this time, the clamping plate 309 cannot move downward, and the retaining ring 302 is also tightly attached to the inner wall of the annular nanocrystalline iron core, which can effectively fix the annular nanocrystalline iron core and prevent the annular nanocrystalline iron core from moving during the winding process.
