Abstract
Description
A magnetic ring fixing mechanism Technical Field
[0001] This utility model relates to the field of magnetic ring processing technology, specifically a magnetic ring fixing mechanism. Background Technology
[0002] A magnetic ring is a ring-shaped electronic component typically made of magnetic materials such as ferrite. Based on the electromagnetic properties of magnetic materials, a guiding magnetic field is generated and concentrated within it when current flows through the winding. It can be used to manufacture inductors, solve electromagnetic compatibility issues, and as a component of transformers. It plays a crucial role in filtering and energy storage in electronic circuits, suppressing internal and external electromagnetic interference, and power conversion. In the manufacturing process of electronic equipment, magnetic rings are widely used as important electronic components in inductors, transformers, and other parts. During the winding, assembly, and testing processes of magnetic rings, precise fixing is required to ensure processing accuracy and product quality.
[0003] Existing magnetic rings come in various specifications, and because they are mostly thin-walled annular structures, uneven clamping force can easily lead to localized stress concentration, resulting in damage and cracks. Existing fixing mechanisms are often only compatible with specific magnetic ring specifications. When faced with magnetic rings of different sizes and shapes, if the chuck and magnetic ring cannot be matched, the clamping force needs to be increased to ensure clamping stability, making the magnetic ring prone to damage and greatly reducing the versatility of the fixing structure. Furthermore, the machining process requires changing the machined surface of the magnetic ring according to requirements. Common clamping structures on the market usually use a fixed clamping angle, which cannot flexibly adjust the magnetic ring's posture. Operators have to repeatedly disassemble and reassemble the magnetic ring, which is not only inefficient but also increases the risk of damage. Therefore, we propose a magnetic ring fixing mechanism.

[0006] Preferably, the second drive assembly includes a servo motor, a first bevel gear, and a second bevel gear. A motor mounting bracket is fixedly connected to the upper surface of the second clamping assembly facing the first clamping assembly. The servo motor is detachably connected to the inner cavity of the motor mounting bracket. The first bevel gear is detachably connected to the power output end of the servo motor. The second bevel gear is detachably connected to the surface of the connecting pipe below the first bevel gear, and the second bevel gear meshes with the first bevel gear.
[0007] Preferably, the second drive assembly includes a handwheel and a drive screw. The drive screw is rotatably mounted inside the adjusting groove cavity, and the handwheel is rotatably nested on the bottom plate surface on one side of the drive screw, with the inner side of the handwheel fixedly connected to the drive screw.
[0008] Preferably, the drive screw is a double-threaded screw, and the two ends of the drive screw surface are provided with opposing threads.
[0009] Preferably, the bottom end of the sliding frame is provided with threaded connection holes along the axial direction of the drive screw, and the lower end of the sliding frame is threaded to the surface of the drive screw through the threaded connection holes.
[0010] Preferably, each of the sliding frames is nested with an air guide pipe on its back. The air outlet end of the air guide pipe is detachably connected to a rotary connector.

[0011] Preferably, a control panel is provided on one side of the base plate, and the servo motor is electrically connected to an external power source through the control panel.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model features a flexible chuck that is rotatably connected to a sliding frame via a connecting pipe. When the chuck contacts the magnetic ring, it adaptively conforms to the arc-shaped surface of the magnetic ring, avoiding stress concentration caused by rigid clamping. An externally provided air pump provides uniform air pressure to the flexible chuck through an air guide pipe and a rotary connector, achieving flexible wrapping clamping. This effectively prevents the thin-walled magnetic ring from breaking due to uneven force, significantly improving the compatibility and clamping stability of the fixing mechanism for various magnetic ring specifications, reducing limitations in use. Furthermore, during clamping and processing, a servo motor precisely drives the connecting pipe and flexible chuck to rotate through the meshing of the first and second bevel gears. This allows the magnetic ring to flexibly adjust the angle of the processing surface while in a fixed state, enabling multi-angle detection and processing. The posture can be changed without disassembling the magnetic ring, effectively reducing manual operation time and the risk of damage from secondary clamping of the magnetic ring, improving the convenience of magnetic ring processing and detection, and significantly increasing processing efficiency.
[0014] 2. This utility model utilizes the interaction of a rotating wheel, an adjusting slide groove, a drive screw, and a threaded connection hole at the lower end of the sliding frame. During fixing, the double-threaded drive screw and the adjusting slide groove work together, allowing the operator to simply rotate the handwheel to simultaneously move the first and second clamping components in opposite directions. This allows for rapid adjustment of the distance between the flexible chucks, quickly adapting to the fixing of magnetic rings with different outer diameters, further reducing the difficulty of fixing, improving the fixing efficiency of magnetic rings during processing and inspection, and further enhancing processing and inspection efficiency.

[0019] 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.
[0020] Example
[0021] Please refer to Figures 1-3. The figures illustrate a magnetic ring fixing mechanism, including a base plate 1. An adjusting groove 2 is formed on the upper surface of the base plate 1. A first clamping assembly 3 and a second clamping assembly 4 are slidably disposed on both sides of the inner cavity of the adjusting groove 2. A first driving assembly is provided within the adjusting groove 2 to drive the movement of the first clamping assembly 3 and the second clamping assembly 4. Both the first clamping assembly 3 and the second clamping assembly 4 include a sliding frame 12 and a flexible clamp 15. A connecting pipe 14 is rotatably disposed on the inner side of the sliding frame 12 at a relative position. The flexible clamp 15 is detachably and interconnected on the inner side of each connecting pipe 14. The second clamping assembly has a second driving assembly for driving the flexible chuck 15 to rotate at the end facing the first clamping assembly 3. The flexible chuck 15 is a German Matrix flexible chuck 15. The German Matrix flexible chuck 15 has many independent and movable flexible levers inside. When it contacts the magnetic ring, these flexible levers can automatically adjust their position by closely following the arc contour of the magnetic ring under the action of the magnetic ring's gravity, accurately adapting to the shape of the magnetic ring, thereby ensuring the uniformity of the force after fixing, avoiding excessive local force that could damage the magnetic ring, and ensuring the protective effect on the magnetic ring during clamping.
[0022] The second drive assembly includes a servo motor 8, a first bevel gear 9, and a second bevel gear 10. A motor mounting bracket 7 is fixedly connected to the upper surface of the second clamping assembly 4 facing the first clamping assembly 3. The servo motor 8 is detachably connected to the inner cavity of the motor mounting bracket 7. The power output end of the servo motor 8 is detachably connected to the first bevel gear 9. The surface of the connecting pipe 14 below the first bevel gear 9 is detachably connected to the second bevel gear 10, and the second bevel gear 10 meshes with the first bevel gear 9. The servo motor 8 can precisely control the speed and angle. Through bevel gear transmission, it can stably drive the connecting pipe 14 and the flexible chuck 15 to rotate freely, so that the magnetic ring can flexibly switch the processing surface in a fixed state, meeting the multi-angle processing needs of multiple processes such as magnetic ring winding, spraying, and inspection. This effectively avoids damage and efficiency loss of the magnetic ring caused by repeated manual disassembly and assembly, and effectively improves the intelligent level and production efficiency of magnetic ring processing.
[0023] The second driving component includes a handwheel 6 and a driving screw 5. The driving screw 5 is rotatably mounted inside the adjusting groove 2. The handwheel 6 is rotatably nested on the surface of the base plate 1 on one side of the driving screw 5, and the inner side of the handwheel 6 is fixedly connected to the driving screw 5. The driving screw 5 is a double-threaded screw, and the two ends of the driving screw 5 have opposing threads. The bottom end of the sliding frame 12 has threaded connection holes 13 along the axial direction of the driving screw 5, and the lower end of the sliding frame 12 is threaded to the surface of the driving screw 5 through the threaded connection holes 13. By simply rotating the handwheel 6, the double-threaded driving screw 5 can convert the rotational motion into linear motion. Through the opposing thread structure at both ends, it synchronously drives the two sliding frames 12 to move towards or away from each other along the adjusting groove 2, accurately and quickly adjusting the spacing of the flexible clamps 15, thereby achieving rapid adaptation to magnetic rings of different outer diameters, effectively reducing the difficulty of fixing, and thus improving clamping efficiency.
[0024] The sliding frame 12 is equipped with an air guide pipe 11 nested on its back. The air outlet end of the air guide pipe 11 is detachably connected to a rotary connector. The air outlet end of the air guide pipe 11 is rotatably connected to the connecting pipe 14 on one side relative to the flexible clamp 15 through the rotary connector 16. The air inlet end of the air guide pipe 11 is connected to an externally provided air pump. The air guide pipe 11 nested on the back of the sliding frame 12, together with the rotary connector, realizes the dynamic connection between the air path and the rotatable connecting pipe 14. When the air pump supplies air, the flexible clamp 15 can achieve uniform and flexible clamping of the magnetic ring, ensuring that the thin-walled magnetic ring is not damaged. At the same time, when the servo motor 8 drives the connecting pipe 14 and the flexible clamp 15 to rotate and adjust the processing angle of the magnetic ring, the air path is guaranteed to be continuously and stably ventilated, avoiding the impact of pipe winding and bending on the clamping force. This provides reliable power transmission and stable clamping guarantee for multi-angle processing of the magnetic ring.
[0025] It should be noted that this utility model is a magnetic ring fixing mechanism. Based on the outer diameter of the magnetic ring, rotating the handwheel 6 utilizes the cooperation of the double-threaded drive screw 5 and the adjusting slide groove 2 to simultaneously drive the sliding frames 12 on the first clamping assembly 3 and the second clamping assembly 4 to move towards or away from each other within the adjusting slide groove 2, adjusting the flexible clamps 15 to a suitable distance. Then, the magnetic ring is placed between the two flexible clamps 15. At this time, the flexible clamps 15 are rotatably connected to the sliding frames 12 via the connecting pipe 14, adaptively conforming to the arc-shaped surface of the magnetic ring. Subsequently, an external air pump is started, and the air pump connects to the rotating frame via the air guide pipe 11. The connector provides uniform air pressure to the flexible chuck 15 to achieve flexible wrap-around clamping and stably fix the magnetic ring. When the magnetic ring needs to be processed or inspected at different angles, the servo motor 8 is turned on. The servo motor 8 drives the connecting tube 14 and the flexible chuck 15 to rotate through the meshing transmission of the first bevel gear 9 and the second bevel gear 10, flexibly adjusting the angle of the magnetic ring processing surface. The posture conversion can be completed without disassembling the magnetic ring, realizing multi-angle process operation. The operation is simple, effectively reducing the difficulty of fixing and improving the fixing efficiency. In turn, it effectively improves the fixing efficiency and processing and inspection efficiency of the magnetic ring and reduces the risk of magnetic ring breakage.
