Description

Technical Field

[0001] This utility model relates to the field of magnetic core processing technology, and more specifically, it relates to a polishing machine for magnetic core processing. Background Technology

[0002] A magnetic core is a sintered magnetic metal oxide composed of various iron oxide mixtures. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical core materials. Manganese-zinc ferrite features high permeability and high magnetic flux density, along with low losses. Nickel-zinc ferrite has extremely high impedance and low permeability (less than a few hundred). Ferrite cores are used in coils and transformers in various electronic devices. After production, magnetic cores often have burrs on their surface, requiring polishing equipment to smooth and flatten the surface.

[0003] For example, the polishing equipment for magnetic core processing disclosed in patent announcement number CN220944723U is configured to polish the magnetic core. When polishing is required, the operator can turn on the drive motor, which will drive the motor to adjust the polishing height of the magnetic core. After the polishing height of the magnetic core is adjusted, the operator can turn on the motor, which will rotate the output shaft and the polishing disc to polish the magnetic core. After polishing is completed, the operator can turn on the drive motor, which will retract the motor upward. Since a rectangular block is fixedly installed on the outer wall of the motor, and a moving block is connected to the inside of the rectangular block through a connecting spring, when the moving block moves downward, it will contact the locking block, causing the motor to vibrate and shake off the debris attached to the outer wall of the polishing disc during polishing.

[0004] However, in practice, existing debris removal methods rely on motor vibration, which has limited effectiveness and may affect polishing accuracy. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a polishing machine for magnetic core processing that can clean more thoroughly.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A polishing machine for magnetic core processing includes a polishing machine body and a polishing disc connected to the polishing machine body. The polishing disc is equipped with an airflow cleaning mechanism and a mechanical cleaning mechanism.

[0008] The airflow cleaning mechanism includes several annular airflow nozzles, an air pump, an air tank, and airflow pipes. The annular airflow nozzles are arranged around the polishing disc, and the airflow pipes are connected to the annular airflow nozzles. The other end of the airflow pipes is connected to the air pump, which is connected to the air tank.

[0009] The mechanical cleaning mechanism has two sets, which are respectively placed on both sides of the polishing disc. The mechanical cleaning mechanism includes a cleaning brush, a connecting rod, a drive motor, a support, a connecting shaft, and a base. One end of the connecting rod is connected to the output end of the drive motor, and the other end is connected to the support through the connecting shaft. The cleaning brush is set parallel to the bottom surface of the polishing disc, and one end of the cleaning brush is connected to the connecting rod. The side wall of the polishing disc is provided with a mounting plate corresponding to the mechanical cleaning mechanism, and the drive motor is rotatably connected to the mounting plate.

[0010] The present invention is further configured such that: the cleaning brush includes a plate and a cleaning cloth connected to the plate, the end face of the plate is provided with a magnetic sheet, the end face of the cleaning cloth is provided with a soft magnetic sheet, the magnetic sheet and the soft magnetic sheet are attracted to each other, and the end face of the cleaning cloth is provided with a plurality of rubber whiskers.

[0011] The present invention is further configured such that: a pressure regulating valve is provided on the airflow duct, and the pressure regulating valve is communicatively connected to the drive motor.

[0012] The present invention is further configured such that: a protrusion is provided on the connecting rod, a spring is connected to the protrusion, the other end of the spring is fixedly connected to the end face of the cleaning brush, an adjustment hole is provided on the cleaning brush, an adjustment screw is provided in the adjustment hole, the adjustment screw is placed in the spring, and the other end of the adjustment screw is threadedly connected to the protrusion.

[0013] The present invention is further configured such that the length of the cleaning brush is half the diameter of the polishing disc.

[0014] The present invention is further configured such that: an optical sensor is provided on the polishing disc, and the optical sensor is communicatively connected to the drive motor.

[0015] Compared with the shortcomings of the prior art, the beneficial effects of this utility model are as follows:

[0016] The combined operation of the airflow cleaning device and the mechanical cleaning device enables efficient and high-quality cleaning of debris from the surface of the polishing disc.

[0017] The high-pressure airflow generated by the annular airflow nozzle can quickly blow away debris from the surface of the polishing disc, resulting in high cleaning efficiency. The rotating brush removes debris from the surface of the polishing disc through its rotational motion, working in conjunction with the airflow cleaning device to further improve cleaning efficiency. This solution has significant advantages such as automation, intelligence, energy saving, and environmental protection. It can significantly improve the cleaning efficiency and service life of polishing equipment, reduce manual intervention and equipment failure, and has broad application prospects.

The operator controls the airflow pressure by adjusting air pressure regulating valve 13. The angle and position of annular airflow nozzle 3 are adjusted to ensure that the airflow covers the surface of polishing disc 2. High-pressure airflow is ejected from annular airflow nozzle 3, blowing away debris from the surface of polishing disc 2. The direction and pressure of the airflow can be dynamically adjusted according to the distribution of debris on the surface of polishing disc 2. Drive motor 9 is started, which drives connecting rod 8 to move. Connecting rod 8 drives cleaning brush 7 to rotate, which in turn drives rotating brush to clean the surface of polishing disc 2.
