Description

Technical Field

[0001] The utility model relates to the technical field of grinders for magnetic core processing, in particular to a grinder for magnetic core processing. 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. The magnetic core often needs to be polished by a grinder during the processing process.

[0003] As disclosed in the utility model with authorization announcement number CN214869239U, a double-sided grinding device for a magnetic core includes a frame, a fixed bracket is fixedly connected to the bottom of the frame, two grinders are arranged on the inner bottom wall of the frame, a magnetic core is arranged between the two grinders, and a clamping and fixing mechanism is arranged on the inner bottom wall and the inner top wall of the frame. The double-sided grinding device for the magnetic core can drive the rotating shaft to rotate through the cooperation between the fixed plate, threaded rod, fixed rod, movable plate, threaded hole, guide rod, arc clamping plate, driven wheel, fixed seat, rotating shaft, driving wheel, transmission belt and servo motor, so that the servo motor can drive the rotating shaft to rotate, and under the action of the driven wheel, driving wheel and transmission belt, the threaded rod can be driven to rotate, thereby making the movable plate move up and down on the threaded rod and driving the arc clamping plate to move, so that the magnetic core can be clamped and fixed to prevent the magnetic core from shifting. However, when the device is in use, the two arc clamping plates are moved toward the middle, so that the magnetic core on the lower arc clamping plate can be clamped and fixed, so that the left and right sides of the magnetic core can be double-sidedly grinded by the grinder, but this also makes the device unable to grind the arc side of the magnetic core well, resulting in a relatively limited grinding range of the device, and even the need for other grinding tools for further grinding.
