[0001] The utility model relates to the technical field of magnetic cores, in particular to a turning jig for processing magnetic cores. Background Art

[0002] A magnetic core refers to a sintered magnetic metal oxide composed of a mixture of various iron oxides. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core materials. Manganese-zinc ferrite has the characteristics of high magnetic permeability and high magnetic flux density, and has the characteristics of low loss. Nickel-zinc ferrite has extremely high resistivity and low magnetic permeability of less than a few hundred. Ferrite cores are used in coils and transformers of various electronic devices. During the processing of the core, the core needs to be clamped and flipped for further processing, which requires the use of a flipping fixture.

[0003] For example, publication number CN219393177U discloses a flipping jig for magnetic core processing, including a base plate and a fixing mechanism; the base plate: a vertical plate 1 and a vertical plate 2 are respectively arranged on the left and right sides of the upper end thereof, the vertical plate 1 and the vertical plate 2 are both rotatably connected to a rotating shaft through a bearing 1, a bearing plate is fixedly connected between the two rotating shafts, a rectangular groove is provided on the inner middle side of the bearing plate, a lead screw is rotatably connected to the inner side of the rectangular groove through a bearing 2, a magnetic core clamp is symmetrically threadedly connected to the outer arc surface of the lead screw, guide grooves are symmetrically provided on the inner side of the bearing plate, guide blocks are respectively arranged on the lower ends of the magnetic core clamps, and the guide blocks are respectively slidably connected to adjacent guide grooves; the fixing mechanism: it is arranged inside the vertical plate 2, the flipping jig for magnetic core processing can flip and fix the magnetic core at multiple angles, the angle adjustment is precise, and the flipping angle of the magnetic core is easy to adjust, the use is more convenient during the magnetic core processing, the fixing block can be quickly replaced, and the use is more convenient.

At this time, the magnetic core with the same angle as the magnetic core can be clamped and fixed, while other magnetic cores with different angles from the magnetic core cannot remain stable. Therefore, the risk of falling off is relatively high when they are processed, thereby achieving the effect of facilitating the clamping and limiting of magnetic cores at different angles.

[0028] As a technical optimization solution of the utility model, by setting a connecting component 11, a connecting plate 111 and a telescopic rod 112 are used to connect the rubber column 9 and the connecting plate 102. The elasticity of the spring 113 can make the rubber column 9 elastic, so that the rubber column 9 can adapt to grooves of different depths on the magnetic surface.

[0029] refer to Figure 2 and Figure 3 The top and bottom of the connecting block 103 are fixedly connected with the sliding block 12, the top and bottom of the inner wall of the slide rail 101 are provided with a sliding groove 13, and the surface of the sliding block 12 is slidably connected to the inner wall of the sliding groove 13.

[0031] refer to Figure 3 The outer side of the connecting block 103 is fixedly connected to a limiting plate 14 , the inner side of the limiting plate 14 is in contact with the outer side of the clamping plate 4 , and the outer side of the limiting plate 14 is fixedly connected to a handle 15 .

[0032] As a technical optimization scheme of the utility model, a limit plate 14 and a handle 15 are provided, and the limit plate 14 is used to connect the handle 15 and the connecting block 103. By moving the handle 15, the limit plate 14 can be driven to move left and right. The left and right movement of the limit plate 14 can drive the connecting block 103 to move left and right. The left and right movement of the connecting block 103 can drive the connecting plate 102, the U-shaped shell 7 and the rubber column 9 to move left and right, thereby facilitating the user to adjust the position of the rubber column 9 according to the position of the magnetic core.

[0033] refer to Figure 4 Both sides of the clamping plate 4 are movably connected with a rotating plate 16 through hinges, and the bottoms of both sides of the clamping plate 4 are fixedly connected with a fixed plate 17, and the bottom of the rotating plate 16 is in contact with the top of the fixed plate 17.

[0034] As a technical optimization solution of the utility model, by setting a rotating plate 16 and a fixed plate 17, the rotating plate 16 and the fixed plate 17 can close the slide rail 101, thereby preventing the connecting block 103 from escaping from the inside of the slide rail 101. By adjusting the rotating plate 16, the user can easily remove individual connecting blocks 103 from the slide rail 101 or move excess connecting blocks 103 into the inside of the slide rail 101.

[0035] refer to Figure 4 A snap-in groove 18 is provided at the top of the fixed plate 17, and a snap-in plate 19 is fixedly connected to the bottom of the rotating plate 16. The front and rear sides of the snap-in plate 19 are movably connected to the front and rear sides of the inner wall of the snap-in groove 18. A rotating rod 20 is provided on the outer side of the fixed plate 17. One end of the rotating rod 20 close to the fixed plate 17 passes through the fixed plate 17 and the snap-in plate 19 in sequence and extends to the inner side of the fixed plate 17. The rotating rod 20 is threadedly connected to the fixed plate 17 and the snap-in plate 19.

[0036] As a technical optimization solution of the utility model, by setting a clamping groove 18, a clamping plate 19 and a rotating rod 20, the clamping groove 18 can limit the clamping plate 19 forward and backward, and the rotating rod 20 is used to connect the clamping plate 19 and the fixed plate 17, thereby preventing the rotating plate 16 from shaking when clamping the magnetic core, causing the connecting block 103 to disengage from the inside of the slide rail 101.

[0037] The working principle and use process of the utility model are as follows: when in use, when it is necessary to clamp the magnetic core, first, the rotary rod 20 is rotated to disengage the rotary rod 20 from the clamping plate 19, and then the slide rail 101 is turned to connect with the outside world, and then the corresponding number of connecting blocks 103 with rubber columns 9 are moved in according to the number of magnetic cores to be processed, and then the rotating plate 16 is restored to its original position to make the clamping plate 19 enter the inside of the clamping groove 18, and then the rotary rod 20 is rotated to reconnect and fix the clamping plate 19 with the fixing plate 17, and then the magnetic core is placed on the top of the receiving plate 3. Since the threads on the surfaces at both ends of the screw rod 6 are opposite, the two clamping plates 4 can be driven to move toward the middle of the receiving plate 3 to clamp the magnetic core by rotating the screw rod 6, and at the same time, the rubber column 9 can press the groove on the surface of the magnetic core. When the groove is not deep, the magnetic core can press the rubber column 9 against the inside of the U-shaped shell 7. At this time, the spring 113 and the telescopic rod 112 are contracted at the same time, so that the two clamping plates 4 can remain relatively parallel.

[0038] To sum up: this kind of flip jig for processing magnetic cores, by setting a U-shaped shell 7, a through hole 8 and a rubber column 9, the U-shaped shell 7 and the through hole 8 can limit the rubber column 9 up, down, left and right. When the clamping plate 4 is moved to clamp the magnetic core, the rubber column 9 can first limit the groove on the surface of the magnetic core, thereby preventing the magnetic core from shaking between the clamping plates 4, solving the problem that the clamping surface of the magnetic core clamp in the device is relatively flat, while the shape of the magnetic core on the market is usually irregular, with grooves and protrusions. At the same time, the user cannot ensure that the angles of the magnetic cores placed on the supporting plate are completely consistent. Therefore, when the two magnetic core clamps move toward each other to clamp the magnetic core, the magnetic core clamps stop when they first touch one end of the magnetic core. At this time, the magnetic core with the same angle as the magnetic core can be clamped and fixed, while other magnetic cores with different angles from the magnetic core cannot remain stable, so there is a greater risk of falling when processing them.
