[0015] The present invention has the following beneficial effects:

[0016] (1) For the burr cleaning device for the green blank of the soft ferrite magnetic core of the present invention, first pull apart the circular plate and the grinding block three, place the magnetic core on the grinding block one, then start the driving motor. The driving motor drives the reciprocating screw rod to rotate. The reciprocating screw rod drives the gear to rotate. Under the action of the gear and the annular gear sleeve, the rotating plate is driven to rotate. The rotating plate drives the telescopic sliding rod to rotate. The telescopic sliding rod drives the movable circular plate to rotate. Since the magnetic core is sleeved on the grinding block one, a centrifugal force will be generated when the grinding block one rotates. The grinding block one will drive the magnetic core to rotate under the action of the centrifugal force. During the rotation of the magnetic core, the inner wall of the magnetic core will continuously contact and rub against the grinding block one, so as to grind off the burrs on the inner wall of the magnetic core. Under the limiting action of the telescopic spring two and the grinding block three, it is ensured that the magnetic core will not fall off;

[0017] (2) In the process of the reciprocating screw rotating, it will drive the internal thread block to move. The internal thread block drives the push rod to move towards the driving motor. The push rod drives the annular sleeve to move towards the driving motor. The annular sleeve drives the L-shaped rod to move. The L-shaped rod drives the circular plate to move. Under the action of the second telescopic spring, the circular plate drives the grinding block three to press downwards to increase the friction between the grinding block three and the magnetic core. The grinding block three also drives the magnetic core to increase the friction with the grinding block two, so that the grinding block three and the grinding block two simultaneously grind the magnetic core, and grind the burrs on the front and back of the magnetic core.

[0018] (3) In the process of the circular plate moving, it will drive the buffer rod to move. Under the pulling force of the buffer spring, the buffer rod pushes the buffer rod to apply force towards the grinding block three and contact the magnetic core. The buffer rod will drive the arc-shaped box to press towards the grinding block three. The grinding block three will drive the arc-shaped plate into the limiting block to improve the stability of the grinding block three. The balance balls in the arc-shaped box will contact the magnetic core. When the magnetic core rotates, it drives several balance balls to rotate. The contact of the balance balls will improve the stability of the magnetic core during rotation and ensure the uniformity of grinding.

[0019] (4) In the process of the circular plate moving, it will also drive the telescopic push rod to move. The telescopic push rod pushes the air in the cylinder into the air delivery cylinder. Then the air again drives the air delivery rod in the air delivery cylinder to move. The air delivery rod drives the support box to move and抵住 the inner wall of the magnetic core to force the magnetic core to stop rotating. When the support box moves, the contact rod will contract when it contacts the inner wall of the magnetic core. Under the action of the two rotating rods, the contact rod will drive the two reinforcing rods to adjust the angle. The reinforcing rods will abut against the inner wall of the magnetic core to further enhance the stability of the magnetic core. In the process of the annular sleeve moving, it will drive the support rod to move. The support rod will drive several arc-shaped grinding plates to disperse and slide on the C-shaped limiting rod until the C-shaped limiting rod contacts the magnetic core. At this time, the magnetic core loses centrifugal force and will not rotate by itself, and can only rotate synchronously with the rotating plate. During the rotation of several magnetic cores, they will contact several arc-shaped grinding plates to grind the arc-shaped grinding plates. When the internal thread block returns under the action of the reciprocating screw, it also completes the work of grinding and deburring several magnetic cores.

[0020] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
