Description

Technical Field

[0001] This utility model relates to the field of ferrite core grinding, specifically a ferrite core grinding machine. Background Technology

[0002] Ferrite cores are mainly composed of three metallic elements: iron (Fe), manganese (Mn), and zinc (Zn). They are commonly known as manganese-zinc ferrite and are a high-frequency magnetic material (the principle is the same as that of silicon steel sheets, but it is used in a high-frequency environment). They are mainly used to make high-frequency transformers (such as switching power supplies, horizontal output transformers, etc.), high-frequency magnetic rings (for anti-interference), etc., to increase magnetic permeability.

[0003] In the prior art, after the production of ferrite cores, the outer surface of the ferrite cores needs to be ground to ensure that the surface of the ferrite cores is smooth. However, the specifications of ferrite cores are different, and the height of the grinding rollers needs to be adjusted according to the needs. For example, the volume of the central column of the can-shaped core is large, and the position of the adjusting worm gear is far back. During manual adjustment, it is not convenient to observe the distance between the material and the grinding rollers. Based on this, this utility model proposes a ferrite core grinding machine.

[0018] 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.

[0019] Please see Figures 1-3 In this embodiment of the present invention, a ferrite core grinding machine includes a working platform 1, a grinding roller 2 for grinding the magnetic core is installed on the outer wall of the working platform 1, a movable plate 3 is slidably installed on the outer wall of the working platform 1, a lifting plate 4 is vertically slidably installed on the top of the movable plate 3, and a transmission mechanism 5 is provided on the movable plate 3 and the lifting plate 4; the transmission mechanism 5 includes a limiting unit and a clamping unit; the clamping unit is used to clamp the magnetic core; the limiting unit is used to limit the height of the lifting plate 4.

[0020] The clamping unit includes a lead screw 501 and a clamping block 502. The lead screw 501 is rotatably mounted on the inner wall of the lifting plate 4 and extends to the outside of the lifting plate 4. The lead screw 501 is used to push the clamping blocks 502 closer to each other. The clamping block 502 is slidably mounted on the inner wall of the lifting plate 4 and sleeved on the outer wall of the lead screw 501. The clamping block 502 is used to clamp the material.

[0021] The limiting unit includes a guide rod 503, a rotating rod 504, a positioning block 505, a turntable 506, and a transmission rod 507. The guide rod 503 is fixed to the bottom end of the lifting plate 4 and passes through the movable plate 3. The guide rod 503 is used to guide the vertical movement of the lifting plate 4. The rotating rod 504 is rotatably installed on the inner wall of the hollow movable plate 3 and extends to the outside of the bottom end of the movable plate 3. The rotating rod 504 is used to synchronously drive the turntable 506 to rotate.

[0022] The positioning block 505 is fixed to the outer wall of the rotating rod 504 and is used to limit the rotation of the rotating rod 504. The turntable 506 is rotatably installed on the inner wall of the hollow movable plate 3 and is used to drive one end of the transmission rod 507 to rotate. The transmission rod 507 is rotatably connected to the outer wall of the turntable 506 and is used to pull the limiting block 508 to move axially. The limiting block 508 is axially slidably installed inside the movable plate 3 and is used to limit the vertical movement of the guide rod 503.

[0023] In this embodiment: The magnetic core to be ground can be placed between the clamping blocks 502 using this structure. Rotating the lead screw 501 causes the two clamping blocks 502 to move closer together and clamp the magnetic core. Then, an upward thrust is applied to the rotating rod 504, causing the positioning block 505 at the top of the rotating rod 504 to move out of the limiting groove on the movable plate 3, thus releasing the rotation limit of the rotating rod 504. The positioning block 505, located inside the turntable 506, slides vertically along the interior of the turntable 506. The rotating rod 504 then transmits the rotational force through the positioning block 505. The turntable 506 is fed to the turntable, which in turn drives the turntable 506 to rotate synchronously. The rotating turntable 506 will drive one end of the transmission rod 507, which is eccentrically connected to the outer wall, to rotate circumferentially. The circumferentially rotating transmission rod 507 will pull the limit block 508, which is rotatably connected to the other end, to move axially, so that the limit block 508 moves out of the internal docking groove of the guide rod 503. At this time, the height of the lifting plate 4 can be adjusted to move the magnetic core to the position that needs to be ground. The adjustment position is located on the user's side, which is simple to operate and facilitates accurate adjustment of the grinding height of the magnetic core.

[0024] Please refer to this carefully. Figures 1-3 The rotating rod 504 is vertically slidably connected to the inner wall of the turntable 506. The inner wall of the turntable 506 is formed with a groove for the vertical movement of the positioning block 505. The bottom end of the movable plate 3 is formed with a limiting groove for the positioning block 505 to enter. The inner wall of the movable plate 3 is formed with a movable groove for the axial movement of the limiting block 508. The outer wall of the guide rod 503 is formed with a mating groove for the insertion of the limiting block 508. The transmission rod 507 is eccentrically rotatably connected to the outer wall of the turntable 506. The inner wall of the clamping block 502 is formed with a threaded groove that matches the outer wall of the lead screw 501, and the threaded grooves on the inner walls of the two clamping blocks 502 are opposite.

[0025] In this embodiment: With this structure, under the action of the positioning block 505, the rotating rod 504 rotates and drives the limiting block 508 to move axially and get into the docking groove of the guide rod 503. Then, the positioning block 505 will be aligned with the limiting groove on the movable plate 3, so that the positioning block 505 enters the limiting groove on the movable plate 3 under the action of gravity, thereby limiting the rotation of the rotating rod 504.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
