Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ferrite magnetic general-shaped grinding machine for motors, and more specifically, it completely automates the general-shaped grinding process of ferrite magnetics for motors to improve productivity and reduce manufacturing cost, and improve processing precision. The invention relates to a ferrite magnetic total-form grinding machine for motors, which has made it possible to produce high-quality products.

A motor, which is a typical power machine that uses the rotational force of the rotating shaft by receiving electric power to rotate the rotating shaft, has a stator and a rotor for rotational movement of the rotating shaft.

The stator includes a housing having a magnetic inner surface, and the rotor includes an armature, a commutator, and a brush.

At this time, as the magnetic attached to the inner peripheral surface of the housing of the motor and used for the stator, a ferrite magnetic, which is a ring-shaped magnet formed by using the ferrite material, is generally used.

Ferrite is a metal oxide magnetic material produced by solidifying oxides of manganese, copper, cobalt, nickel, magnesium, etc. and iron oxide powder, has high magnetic flux properties, and has a relatively high resistance value. , High frequency loss is small. Since it does not generate a thin current, it is widely used as a high frequency magnetic core material such as a ferrite core, a ferrite circulator, a ferrite rod antenna, and a dynamic loudspeaker.

The ferrite magnetic becomes a magnetic body, that is, an electromagnet by an induced current, but normally, an electric wire through which a current flows is provided so as to traverse the inside. Therefore, as shown in FIG. 14, a ring-shaped ferrite magnetic is formed in the longitudinal direction of the main body 40. After being cut into pieces and manufactured into an arch shape so as to be easily installed and repaired, a large number of pieces are provided so as to be arranged in a circle on the inner peripheral surface of the housing.

By the way, in general, ferrite magnetic is formed by forming it into a ring shape using ferrite powder and then sintering it at a high temperature in a furnace. Not only are they formed regularly, but the surface is also roughened.

As described above, when ferrite magnets of irregular size and rough surface are inserted and fixed in the motor housing as they are, a large number of them are arranged in a circle on the inner peripheral surface of the housing. Problems of balancing may occur due to different sizes in the process, which may be a factor of reducing the performance of the motor and shortening the life of the motor.

In addition, since the ferrite magnetic used in the motor has cut surfaces on both sides, the cut surfaces of the ferrite magnetics arranged in a circle with the electric wires positioned inside are in contact with each other so as to correspond to each other. Like

By the way, when the abutting cut surfaces of the ferrite magnetic become rough, air gaps are generated between the abutting cut surfaces, and such pores deteriorate the performance of the ferrite magnetic. Comes to bring.

Therefore, the ferrite magnetic used in the motor must have a constant size, and by smoothing the outer peripheral edge, it is necessary to perform shaping to minimize the pores generated in the cut surface where the ferrite magnetic abuts. Must be enforced.

Especially, as the motor has been widely used in expensive products such as automobiles and home appliances, and the function of the motor has become more precise and sophisticated recently, the ferrite magnetic that influences the performance of the motor is shaped. At the same time, there is a demand for higher precision in which ferrite magnetic flatness, uniformity, and smoothness are improved.

Nevertheless, conventionally, the work of shaping the outer peripheral edge of the ferrite magnetic has been done manually.

That is, since a skilled worker fixed the ferrite magnetic to a dedicated jig and then manually processed it using a grinder, not only the productivity was remarkably low due to the decrease in work efficiency, but also the skilled professional work. As a person who performs the shaping process by hand, the precision of the product is not excellent, and it is difficult to maintain uniform product quality and reliability.

In addition, since fine abrasive chips (chips) are scattered during the process of processing ferrite magnetic using a grinder, not only is the working environment in the workplace extremely poor, but the health of workers is also impaired. Therefore, there is a problem that the manufacturing costs of ferrite magnetic increase as workers increase their labor cost by avoiding the processing work of ferrite magnetic. ..

A ferrite core polishing apparatus for improving such a problem has been developed in the past, and a typical conventional technique thereof is as follows.

Korean Patent Registration No. 10-1287934 discloses a body having a space portion provided with a transfer path having an inlet and an outlet through which a core body is charged and discharged, and a transfer path provided on the transfer path.

In a ferrite core bearing surface polishing apparatus configured by pressing means, the polishing means receives a power supply and generates a rotational power; and a polishing motor located in the polishing area for transmitting rotational power of the polishing motor. A ferrite core bearing surface polishing device is disclosed, which includes a plate-shaped polishing plate adapted to receive and rotate to polish the bearing surface of a core body.

By minimizing friction with the ferrite magnetic moving along 301, a low friction member 304, such as Teflon, is embedded to facilitate the movement of the ferrite magnetic, or It can be coated with a low friction material.

The operation relationship of the ferrite magnetic machining apparatus for a motor to which the above-described technique of the present invention is applied will be described below with reference to the accompanying drawings.

In order to sequentially perform automatic shaping of both side surfaces and cutting surface, outer peripheral edge, and inner peripheral edge of the ferrite magnetic for motor using the motor for ferrite magnetic shaping for motor of the present invention, after forming the sintered product, The ferrite magnetic chamfered to the size is continuously loaded on the upper portion of the transfer conveyor 101b so as to be supplied to the guide path 301 of the guide rail 30.

The ferrite magnetic continuously loaded on the upper part of the transfer conveyor 101b is transferred by the transfer conveyor 101b and loaded on the upper part of the guide path 301 of the guide rail 30, and then on the guide path 301 by the driving force of the transfer conveyor 101b. The front and rear surfaces of the loaded ferrite magnetic are pressed into each other while they are in close contact with each other.

When the ferrite magnetic transferred along the guide path 301 reaches the width-edge processing portion 20a, it is provided at the lower part of the guide rail 30 while being fed under a constant pressure by the pressure transfer means 202 of the width-edge processing portion 20a. Both side surfaces and the cut surface of the ferrite magnetic are simultaneously polished by the width edge polishing wheel 201 thus formed.

The ferrite magnetic whose both side surfaces and the cut surface are simultaneously polished by the width-edge processing portion 20a is fed at a constant pressure by the pressure transfer means 202 of the width-edge processing portion 20a, and is pushed by the tail-ferrite magnetic to the guide path 301. When it is transported along and reaches the outer edge processed portion 20b, the outer edge of the ferrite magnetic is polished by the outer edge polishing wheel 203.

The ferrite magnetic whose outer peripheral edge has been polished by the outer edge processing portion 20b is pushed at a constant pressure by the pressure transfer means 202 of the width edge processing portion 20a and is pushed by the rear ferrite magnetic to be transported along the guide path 301. When reaching the inner edge processed portion 20c, the inner edge polishing wheel 204 polishes the inner peripheral edge of the ferrite magnetic and the cut surface at the same time, thereby completing the polishing of the ferrite magnetic.

Therefore, by supplying ferrite magnetic for shaping, both side surfaces of the ferrite magnetic, polishing processing of the cutting surface, the outer peripheral edge, the inner peripheral edge and discharging, all are automatically performed, Mass production of ferrite magnetic becomes easy.

Further, in the ferrite magnetic shaping apparatus for a motor of the present invention, the front and rear surfaces of the ferrite magnetic A are excluded while the ferrite magnetic continuously supplied through the product supply section 10 continuously passes through the shaping processing section 20. Each grinding wheel (201, 203, 201, 203, respectively) that grinds both side surfaces, the cut surface, the outer peripheral edge, and the inner peripheral edge in the process of sequentially performing automatic shaping of the both side surfaces A1, the cut surface A2, the outer peripheral edge A3, and the inner peripheral edge A4. By precisely and automatically controlling the height of 204), the processing precision can be remarkably improved and the product quality and reliability can be improved.

At the same time, when the ferrite magnetic is shaped, by spraying the polishing liquid from the polishing liquid injection nozzle provided on one side of each polishing wheel, the polishing chips and dust generated during the polishing process are washed with the polishing liquid. By being broken and discharged together with the polishing liquid, it becomes possible to prevent the scattering of the polishing chips and dust and to maintain a comfortable working environment.

Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the above-described specific embodiments, and the present invention is applicable without departing from the gist of the present invention claimed in the scope of claims. It goes without saying that various modifications and applications can be made by those having ordinary knowledge in the technical field, and such modifications and applications are individually understood from the technical idea and perspective of the present invention.
