[0023] When the device is needed to be used, the staff first places the device to the designated work area, then respectively rotates the two second sealing covers 8 clockwise to remove them, then the staff pours a certain amount of cooling liquid into the shell 1 through the water inlet pipe 7, when the injected cooling liquid reaches the bottom of the shell 1 and reaches a certain depth, stop injecting new cooling liquid into the shell 1, then the staff respectively rotates the two second sealing covers 8 counterclockwise to install them back to the initial state, then the staff can start polishing the magnetic core, at this time the staff should first manually place a magnetic core on the top of the workbench 2, then push the magnetic core from right to left, so that the magnetic core is pushed into the two rubber blocks 17, at this time the two rubber blocks 17 are extruded and compressed by the magnetic core to be relatively flat, at the same time the magnetic core is fixed and not easy to deviate, then the staff starts the first motor 4 and the second motor 9 to make them work, at this time the output shaft of the first motor 4 rotates and drives the polishing wheel 6 to rotate, that is, the polishing wheel 6 makes the action of preparing to polish the bottom of the magnetic core, at the same time the output shaft of the second motor 9 rotates clockwise and drives the lead screw 10 to rotate clockwise, the lead screw 10 drives the fixed seat 12 to move to the right, at the same time the fixed seat 12 slides to the right on the first guide rod 11, the fixed seat 12 and the rubber block 17 cooperate to drive the magnetic core to move to the right, when the magnetic core contacts the polishing wheel 6 during moving to the right, the bottom of the magnetic core is polished, similarly, when the magnetic core moves to the right limit position, the output shaft of the second motor 9 rotates counterclockwise and drives the lead screw 10 to rotate counterclockwise, the lead screw 10 drives the fixed seat 12 to move to the left, at the same time the fixed seat 12 slides to the left on the first guide rod 11, the fixed seat 12 and the rubber block 17 cooperate to drive the magnetic core to move to the left, when the magnetic core contacts the polishing wheel 6 again during moving to the left, the bottom of the magnetic core is polished again, the output shaft of the second motor 9 rotates intermittently clockwise and counterclockwise repeatedly, which indirectly drives the magnetic core to move to the right and to the left, effectively realizing the repeated polishing of the bottom of the magnetic core.

[0024] When the bottom of the magnetic core is polished and the desired effect is not achieved, because the magnetic core has been thinned at this time, that is, the bottom of the magnetic core is polished to be unable to continue to be in contact with the polishing wheel 6, it is necessary to appropriately adjust the height at which the polishing wheel 6 is located, that is, it is necessary to move the polishing wheel 6 upward by a certain distance, so that the polishing wheel 6 can be in contact with the bottom of the magnetic core and continue to polish the bottom of the magnetic core, at this time, the worker rotates the knob 14 clockwise, the knob 14 drives the screw rod 13 to rotate clockwise, the screw rod 13 drives the wedge block 16 to move to the right, at the same time, the wedge block 16 slides to the right on the second guide rod 15, when the wedge block 16 moves to the right to be in contact with the sliding frame 5, the wedge block 16 lifts the sliding frame 5 upward, the sliding frame 5 drives the fixed frame 3, the first motor 4 and the polishing wheel 6 to move upward, when the wedge block 16 moves to the right to the limit position, the sliding frame 5 is lifted to the limit state upward, the fixed frame 3, the first motor 4 and the polishing wheel 6 also move to the limit state, at this time, the polishing wheel 6 realizes the continuous polishing of the magnetic core, so that the polishing effect of the magnetic core is in the ideal state, then the worker turns off the first motor 4 and the second motor 9 to make them pause, and rotates the knob 14 counterclockwise, the knob 14 drives the screw rod 13 to rotate counterclockwise, the screw rod 13 drives the wedge block 16 to move to the left, at the same time, the wedge block 16 slides to the left on the second guide rod 15, when the wedge block 16 moves to the left to be out of contact with the sliding frame 5, the sliding frame 5 drives the fixed frame 3, the first motor 4 and the polishing wheel 6 to move downward under the action of their own gravity, so that the sliding frame 5, the fixed frame 3, the first motor 4 and the polishing wheel 6 are in the initial state, then the worker can take down the polished magnetic core, if it is necessary to continue to polish other magnetic cores, the above steps can be repeated; during the polishing process, heat will be generated due to friction, which will cause the temperature inside the shell 1 to rise, at this time, the injected cooling liquid can effectively absorb this part of heat, so as to ensure that the ambient temperature of the shell 1 will not be too high, thereby avoiding the adverse effect on the performance of the magnetic core.
