[0002] The multi-channel magnetic blocks in the 800G communication module mainly refer to magnetic material components used in electromagnetic shielding or inductor components. The grinding process is crucial. Rough surfaces can cause uneven magnetic field distribution, leading to signal crosstalk. The roughness needs to be reduced to Ra≤0.05μm through grinding. The magnetic blocks need to be clamped during the grinding process.

[0003] In the existing technology, when processing magnetic blocks, the surface needs to be polished to ensure that the surface of the magnetic block is smooth. However, during polishing, the existing clamping fixture is inconvenient to push and pull, requiring manual pushing and pulling, which is inconvenient to operate.

[0004] Therefore, this utility model provides a clamping fixture for processing magnetic blocks. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 5 As shown, the present invention discloses a clamping fixture for processing magnetic blocks, comprising a base plate 1; a material feeding groove 11 is provided on the base plate 1; a grinding box 12 is fixedly connected to the base plate 1, and the bottom end of the grinding box 12 is connected to the material feeding groove 11; an opening groove 13 is provided on the side wall of the grinding box 12; a placement plate 14 is slidably connected in the material feeding groove 11, and the placement plate 14 has a T-shaped cross-section; a pair of T-shaped sliding grooves 15 are provided at the bottom end of the base plate 1, symmetrically distributed about the material feeding groove 11; a pair of T-shaped blocks 16 are fixedly connected to the placement plate 14, symmetrically distributed about the material feeding groove 11; the T-shaped blocks 16 are slidably connected to the T-shaped sliding grooves 15. The placement plate 14 is moved by a power component within the groove 15; a clamping component is provided at the top of the placement plate 14. In the prior art, when processing magnetic blocks, the surface needs to be polished to ensure that the surface of the magnetic block is smooth. However, during polishing, the existing clamping fixture is inconvenient to push, requiring manual pushing and pulling back and forth, which is inconvenient. Therefore, in this invention, a power component is used to push the placement plate 14 back and forth during operation. The operator only needs to place and remove the magnetic block. At the same time, the clamping component is used to clamp the magnetic block when it is placed on the placement plate. This reduces the manual intervention, improves work efficiency, and avoids the rapid increase of human fatigue.

[0026] The power component includes a servo motor 2; the servo motor 2 is fixedly connected to the side wall of the grinding box 12 via an L-shaped plate; the output end of the servo motor 2 is provided with a first lead screw 21; a fixing block 22 is fixedly connected to the bottom end of the placement plate 14; the fixing block 22 is connected to the first lead screw 21 via a lead screw and nut pair; during operation, the servo motor 2 operates, and through the rotation of the first lead screw 21, it drives the fixing block 22 and the placement plate 14 to move back and forth, completing the intelligent back and forth movement operation. At the same time, the grinding box 12 has a grinding mechanism, which is existing technology and will not be described in detail.

[0027] The clamping member includes a first through groove 23; the placement plate 14 has a first through groove 23; the placement plate 14 has a slidable clamping plate 24, and the clamping plate 24 is pushed by a pushing unit;

[0028] The pushing unit includes a first cylinder 25; a pair of symmetrically distributed first cylinders 25 are provided below the placement plate 14; a piston rod 26 is provided at the output end of the first cylinder 25; a push plate 27 is fixedly connected to the end of the piston rod 26; the push plate 27 is slidably connected in the first through groove 23, and the top end of the push plate 27 is fixedly connected to the bottom of the clamping plate 24.

[0029] Pressure sensors are provided on the opposing surfaces of the pair of clamping plates 24;

[0030] During operation, when the magnetic block is manually placed on the placement plate 14, a pair of first cylinders 25 are simultaneously activated. The piston rod 26 drives the push plate 27 to move, which in turn drives a pair of clamping plates 24 to move towards each other, thus completing the clamping operation of the placed magnetic block. The magnetic block is generally square. Since the clamping plate 24 is equipped with a pressure sensor, the first cylinder 25 can automatically adjust according to the different clamping widths of the magnetic block, without the need for manual operation.

[0031] The first cylinder 25 is slidably connected to the bottom end of the placement plate 14; a moving block 31 is fixedly connected to the bottom end of the first cylinder 25; a positioning plate 3 is fixedly connected to the bottom end of the placement plate 14; a bidirectional lead screw 32 is rotatably connected to the positioning plate 3; a pair of moving blocks 31 are both connected to the bidirectional lead screw 32 through a lead screw nut pair; a turntable 33 is fixedly connected to one end of the bidirectional lead screw 32; during operation, the rotation of the bidirectional lead screw 32 can drive the first cylinder 25 to move, thereby adjusting the distance between the pair of first cylinders 25, thus facilitating the application of magnetic blocks of different widths, but for the same batch of identical magnetic blocks, only one adjustment is needed.

[0032] The turntable 33 has a set of threaded grooves 35; the placement plate 14 has a positioning hole 34 on its side wall; a threaded insertion rod 36 is threadedly connected to the threaded groove 35; during operation, the operation of the threaded groove 35, the positioning hole 34 and the threaded insertion rod 36 can keep the bidirectional lead screw 32 in a fixed state after adjustment, and prevent it from rotating in the opposite direction.

[0033] The clamping plate 24 has a set of arc-shaped grooves 37 at its bottom end; a ball 38 is provided in the arc-shaped grooves 37; the opening diameter of the arc-shaped grooves 37 is smaller than the diameter of the ball 38; during operation, the arc-shaped grooves 37 and the ball 38 facilitate the movement of the clamping plate 24 and reduce friction.

[0034] Working principle: A power component drives the placement plate 14 to move back and forth. The operator only needs to place and remove the magnetic block. Simultaneously, the magnetic block is held in place by a clamping device on the placement plate. This reduces manual intervention, improves work efficiency, and avoids rapid increases in worker fatigue. The servo motor 2 rotates the first lead screw 21, which in turn drives the fixed block 22 and the placement plate 14 to move back and forth, completing the intelligent back-and-forth movement operation. The grinding box 12 contains a grinding mechanism, which is existing technology and will not be described in detail. The magnetic block is placed on the placement plate 14 manually. Then, a pair of first cylinders 25 are activated simultaneously, driving the push plate 27 to move via the piston rod 26, which in turn drives a pair of clamping plates 24 to move towards each other, completing the clamping operation of the placed magnetic block. The magnetic block is generally square. Because the clamping plate 24 is equipped with a pressure sensor, the first cylinder 25 can automatically adjust according to the different clamping widths of the magnetic block without manual operation. The rotation of the bidirectional lead screw 32 can drive the first cylinder 25 to move, thereby adjusting the distance between the pair of first cylinders 25, thus facilitating the application of magnetic blocks of different widths. However, for the same batch of identical magnetic blocks, only one adjustment is needed.
