As a metal oxide composed of a sintered mixture of various iron oxides, magnetic cores possess characteristics such as high permeability and high magnetic flux density, enabling efficient electromagnetic conversion.

[0003] Meanwhile, the patent specification with application number CN208400707U discloses a magnetic core clamping device, "including a placement plate, a clamping plate on one side of the placement plate, a telescopic rod on the outer wall of the clamping plate away from the placement plate, a first servo motor fixedly connected to the end of the telescopic rod away from the clamping plate, a support frame fixedly connected to the outer wall of the first servo motor away from the telescopic rod, a sliding block on the outer wall of the placement plate away from the clamping plate, a sliding plate slidably connected to the outer wall of the sliding block away from the placement plate, a second servo motor fixedly connected to the outer wall of the sliding plate away from the sliding block, and a limit block movably connected to the upper surface of the sliding block"; Existing magnetic core metal clamp anti-offset positioning components can only achieve bidirectional clamping during use; while the centripetal clamping structure designed for irregular magnetic cores has unreasonable layout problems, resulting in insufficient clamping stability for irregular magnetic cores and easy offset during processing.

[0004] Therefore, a magnetic core metal clamp anti-offset positioning component is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a magnetic core metal clamp anti-offset positioning component, which effectively improves the problem of insufficient stable clamping of irregular magnetic cores by traditional bidirectional clamping and the offset problem caused by unstable clamping during processing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a magnetic core metal clamp anti-offset positioning component, including a fixed frame, four fixed blocks are fixedly connected to the bottom end of the fixed frame, two corresponding fixed blocks are rotatably connected to a bidirectional lead screw, and movable blocks are threadedly sleeved at the outer surfaces of the two bidirectional lead screws where threads in different directions are engraved, the top end of the fixed frame is provided with a movable groove for use with the four movable blocks, the top ends of the four movable blocks respectively pass through the four movable grooves and extend to the top of the fixed frame, and a positioning rod is fixedly connected to one end of each of the four movable blocks facing the center of the fixed frame.

[0007] Preferably, the two corresponding fixed blocks are mirror images of each other, and the two corresponding fixed blocks are the same size.

[0008] Preferably, all four positioning rods have a wedge-shaped gradient structure, and the positioning rods gradually narrow from the end connected to the moving block towards the center of the fixed frame. The narrowest end face of the positioning rod is provided with a buffer pad, which is composed of several buffer protrusions. The top of the fixed frame is embedded with a positioning pad.

[0009] Preferably, one end of each of the two bidirectional lead screws passes through one of the fixing blocks and is fixedly connected to an operating knob.

[0010] Preferably, the upper bidirectional lead screw and the lower bidirectional lead screw do not contact each other in space, and the projections of their axes on the horizontal plane are perpendicular to each other, forming a cross-shaped layout.

[0011] Preferably, the four movable slots are arranged in a circular array, and two guide slots are opened on the inner walls of both sides of the movable slots. A guide block that cooperates with the two guide slots is fixedly connected to the outer surface of the movable block. The cross-section of the guide block and the guide slot is wedge-shaped.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting two bidirectional lead screws, generates a multi-directional centripetal clamping force under the action of driving the corresponding moving blocks to move synchronously towards the center of the magnetic core from four directions. This effectively improves the problem of insufficient stable clamping of irregular magnetic cores by traditional bidirectional clamping and the problem of offset caused by unstable clamping during processing.

[0015] 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.

[0016] like Figures 1 to 4 As shown, this utility model provides a magnetic core metal clamp anti-displacement positioning component, including a fixed frame 1. Four fixed blocks 2 are fixedly connected to the bottom end of the fixed frame 1. Two corresponding fixed blocks 2 are rotatably connected to a bidirectional lead screw 22. The outer surfaces of the two bidirectional lead screws 22 are threaded with moving blocks 3 at the points where threads in different directions are engraved. The top end of the fixed frame 1 is provided with a moving groove 12 for use with the four moving blocks 3. The top ends of the four moving blocks 3 pass through the four moving grooves 12 and extend to the top of the fixed frame 1. The end of each of the four moving blocks 3 facing the center of the fixed frame 1 is fixedly connected to a positioning rod 4. The bidirectional lead screw 22 is supported by the four fixed blocks 2. With the synergistic action of the moving blocks 3 and the positioning rod 4, a stable four-way clamping base structure is formed, providing reliable support for the subsequent anti-displacement function.

[0017] Specifically, the two corresponding fixed blocks 2 are mirror images of each other, and the two corresponding fixed blocks 2 are the same size. The mirror images of the fixed blocks 2 with the same size can ensure that the forces at both ends of the bidirectional lead screw 22 are balanced, avoid the lead screw tilting due to installation deviation, and ensure the accuracy of the movement trajectory of the moving block 3.

[0018] like Figures 1 to 4 As shown, all four positioning rods 4 have a wedge-shaped gradient structure. The positioning rods 4 gradually narrow from the end connected to the moving block 3 towards the center of the fixed frame 1. The narrowest end face of the positioning rod 4 is provided with a buffer pad 41, which is composed of several buffer protrusions. The top of the fixed frame 1 is embedded with a positioning pad 11. The wedge-shaped gradient structure of the positioning rods 4 can adapt to irregularly shaped magnetic cores of different sizes. The buffer protrusions of the buffer pad 41 can disperse the clamping force and avoid damage to the surface of the magnetic core. The positioning pad 11 can assist in fixing the magnetic core from the bottom and improve the overall stability.

[0019] Furthermore, one end of each of the two bidirectional lead screws 22 passes through one of the fixed blocks 2 and is fixedly connected to an operating knob 21. The operating knob 21 facilitates manual adjustment of the bidirectional lead screws 22, enabling rapid positioning of the moving block 3, reducing operational difficulty, and improving clamping efficiency.

[0020] like Figures 1 to 4As shown, the upper bidirectional lead screw 22 and the lower bidirectional lead screw 22 do not contact each other in space, and the projections of their axes on the horizontal plane are perpendicular to each other, forming a cross-shaped layout. The cross-shaped bidirectional lead screw 22 can drive the positioning rod 4 from two vertical directions, horizontal and vertical, to form a multi-directional centripetal clamping force, which solves the problem of insufficient stable clamping of irregular magnetic cores by traditional bidirectional clamping.

[0021] It is worth noting that the four moving slots 12 are arranged in a circular array, and two guide slots 121 are opened on the inner walls of both sides of the moving slots 12. The outer surface of the moving block 3 is fixedly connected with guide blocks 122 that cooperate with the two guide slots 121. The cross-sections of the guide blocks 122 and the guide slots 121 are both wedge-shaped. The wedge-shaped guide blocks 122 cooperate with the guide slots 121 to eliminate gaps when the moving block 3 moves, improve the guiding accuracy, avoid jamming or shaking during the movement, and ensure the accuracy of the clamping position of the positioning rod 4.

[0022] Working principle and process: Rotating the operating knob 21 drives the bidirectional lead screw 22 to rotate. The reverse thread of the bidirectional lead screw 22 drives the moving block 3 to move synchronously closer to or further away from the center of the fixed frame 1 along the moving groove 12. The moving block 3 drives the positioning rod 4 to move. The wedge-shaped fit between the guide block 122 and the guide groove 121 ensures the smooth movement of the moving block 3. The cross-shaped bidirectional lead screw 22 enables the positioning rod 4 to form a centripetal clamping force from four directions. The wedge-shaped gradually changing positioning rod 4 is adapted to irregular magnetic cores. The buffer pad 41 and the positioning pad 11 further enhance the clamping stability, thereby achieving anti-offset positioning during magnetic core processing.
