The rotating panel 4 is formed in a substantially disk shape with a plurality of permanent magnets 41 on the upper surface thereof, and is disposed below the outer container 21, and the upper surface of the rotating panel 4 is the bottom surface of the outer container 21. 1mm to 2mm away from the state, is installed on the motor shaft 52 of the drive unit 5 to be described later rotates. Accordingly, when the rotary panel 4 is rotated while the workpiece WP and the abrasive A are inserted into the inner container 22, the abrasive A moves violently in accordance with the magnetic field of the permanent magnet 41. Remove the grime of). A description thereof will be described later.

The above-described rotating panel 4 may use a known one as disclosed in the published Utility Model Application No. 20-1998-0016096 and Utility Model Application No. 20-2006-0026470, and the description thereof is well known. Detailed description will be omitted.

The cover 7 opens and closes the upper end of the inner container 22, and a plurality of injection holes 71 are formed at equal intervals on the circumferential bottom surface in the shape of a substantially disk, and cold injected from the injection holes 71 at the edge. A discharge hole 72 through which air is discharged is formed. At this time, the injection hole 71 formed in the cover 7 is formed to be inclined from the top to the bottom, inclined in the direction in contact with the circumference of the cover 7, the upper end of the cover 7 an external air pump (not shown) The injection hole 73 is connected to the plurality of injection holes 71 is formed to be connected to. Accordingly, while the air injected from the injection hole 71 forms a whirlwind inside the inner container 22, the abrasive A and the workpiece WP introduced into the inner container 22 are cooled to cool the inner container 22. The hot heat formed therein is discharged through the discharge hole 72. That is, when removing the grime of the workpiece WP while the abrasive A is moving, the temperature of the workpiece WP and the abrasive A may increase due to frictional heat, but the temperature of the workpiece WP and the abrasive A may increase. Ascending, the softening of the grime may not remove the grime. Accordingly, the work WP and the abrasive A are cooled by blowing cold air into the inside of the inner container 22 so that the work WP and the abrasive A are kept in a hard state.

Hereinafter, the operating state of the burr removing apparatus according to the embodiment of the present invention will be described in detail with reference to FIGS. 3 to 7.

First, the size of the abrasive A is selected according to the size of the work W. P, and then the work W and the abrasive A are introduced into the inner container 22.

Then, the first elevating unit 31 and the second elevating unit 32 are operated at the same time using the control unit 6 to raise the outer container 21, and then the inner container 22 is inserted into the outer container 21. Let's do it. This is to prevent the abrasive A from reacting to the magnetic field of the permanent magnet 41 installed in the rotating panel 4 so that the inner container 22 is suddenly inserted into the outer container 21.

When the inner container 22 is inserted into the outer container 21, the first lifting unit 31 and the second lifting unit 32 are simultaneously operated using the control unit 6 to lower the outer container 21. At this time, by using the control unit 6 to adjust the height of the outer container 21 according to the material of the workpiece (W.P). That is, in the case of the hard work WP, the distance between the rotating panel 4 and the outer container 21 is narrowed to be 2 mm to 4 mm. In the case of the soft work WP, the rotating panel 4 and the outer container are narrowed. The distance between 21 is adjusted so that the distance between them may be 5 mm-10 mm. This is because, since the abrasive A is affected by the strength of the magnetic field, the greater the strength of the magnetic field, the more intensely the abrasive A moves, and the weaker the magnetic field, the slower the movement.

However, when the abrasive A is violently operated to remove the grime of the soft workpiece W.P, the outer surface of the workpiece W.P may be damaged, so it is necessary to drop the abrasive A from violently moving. Therefore, by adjusting the distance between the rotating panel 4 and the outer container 21, by controlling the intensity of the magnetic field, it is possible to control the movement of the abrasive (A).

When the distance between the rotating panel 4 and the outer container 21 is determined, the cover 7 is covered on the upper end of the inner container 22.

When the cover 7 is installed on the upper end of the inner container 22, the driving motor 51 is operated to rotate the rotating panel 4. Then, by operating the external air pump to blow cool air into the interior of the inner container 22 to continuously cool the workpiece (W.P) and the abrasive (A). At this time, the cool air supplied to the inside of the inner container 22 evenly spreads into the inside of the inner container 22 while forming a whirlwind, and hot heat is discharged through the discharge hole 72.

As the rotating panel 4 rotates, the permanent magnet 41 rotates together, the magnetic field changes inside the inner container 22, and the abrasive A starts to move. As the abrasive A moves, the workpiece WP moves. Remove the grime of

Here, in the process of removing the burrs of the workpiece W.P, the workpiece W.P may be driven to the edge of the inner container 22 or to either side.

Therefore, the operating time of the first elevating unit 31 and the second elevating unit 32 is input through the control unit 6 to operate the first elevating unit 31 and the second elevating unit 32 every set time. The outer container 21 is inclined back and forth. That is, when the operation of the outer container 21 is repeatedly performed for a set time, the work W. P gathered at the edge of the inner container 22 is uniformly dispersed while spreading back and forth.

When the operation of the outer container 21 is completed for a set time, it returns to the initial height of the outer container 21 to continuously remove the burrs of the workpiece W.P.

When the removal of the debris of the workpiece WP is completed, the cover 7 is opened and the first lifting unit 31 and the second lifting unit 32 are operated simultaneously to raise the outer container 21 by a predetermined height while the outer container ( Only the second lifting portion 32 is operated so that 21 is inclined forward.

When the operation of the second lifting unit 32 is stopped, the inner container 22 is separated from the outer container 21 by holding the handle 222 of the inner container 22.

Therefore, the present invention can remove the inner container with a small force because the inner container is removed after removing the magnetic field formed in the inner container, in particular, because the inner container is taken out in an inclined state, the inner container with a smaller force. Can be separated from. In addition, since the strength of the magnetic field can be adjusted, the use of abrasives formed of the same magnetic material, that is, only different sizes of abrasives can be used, thereby reducing maintenance costs, and the degree of removal of burrs can be adjusted according to the material of the workpiece. This means that even at the same rotational speed, the removal time of the burrs can be controlled by adjusting the strength of the magnetic field.

In describing the present invention described above, even if the embodiment is different, the same reference numerals are used for the same configuration, and the description may be omitted as necessary.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Shall not be construed as being understood. Therefore, a person having ordinary knowledge in the technical field to which the present invention pertains may easily implement other forms of the present invention within the same scope as the above-described embodiments, or the present invention only by the description of the embodiments of the present invention.
