The grinding unit 105 may replace the grinding unit 100 of FIGS. 1 and 2.

If the grinding unit 105 is employed in the grinders 114, 118 of FIGS. 1 and 2, the handles 20 of FIGS. 1 and 2 can be removed from the sidewall of the dust collecting housing 10.

6 to 8 are schematic views illustrating a method of using the grinder of FIG.

Referring to FIG. 6, in order to form the hull 140 of a ship, after the hull process is performed, the hull 140 of the ship is placed in an eyepiece facility (not shown in the drawing) to receive a design process. The surface S1 of the hull 140 may include rust 145 in response to climate change during the performance of the hull process. After the hull 140 is located in the eyepiece facility, the grinder 114 of FIG. 1 is prepared for performing the design process.

The reservoir 120 is connected to the exhaust port 19 of the grinder 114. The reservoir 120 includes a pump and a collector. The power supply unit 130 is electrically connected to the grinding unit 100 and the reservoir 120 of the grinder 114. The pump may receive power from the power supply unit 130 and send air in the dust collecting housing 10 to the dust collecting unit.

The dust collecting part filters foreign substances in the air of the dust collecting housing 10 to accumulate foreign substances therein and discharges the rest to the outside. In this case, the motor 60 of the grinding unit 100 rotates the cutting blade 90 in the second direction R2 through the rotation shaft 80. Next, the grinder 114 is held by the operator through the handles 20 and directed in the third direction R3.

Referring to FIG. 7, first, the grinder 114 is contacted on the surface S1 of the hull 140 through the dust collecting fence 54. When the worker continues to apply the force to the grinder 114 in the third direction R3, the dust collecting fence 54 is pressed by the hull 140 and together with the plurality of rolls 44 the hull ( 140). In addition, the folding portion 16 of the dust collecting housing 10 of the grinder 114 is folded in the first direction R1 to cause a length change in the first direction R1.

Through this, the dust collecting housing 10 reduces the volume of the internal space through the folding portion 16. In addition, the abrasive blade 90 of the grinding unit 100 is inserted into the cutting guide opening 13 of the dust collecting housing 10 in response to a change in the length of the folding portion 16 of the dust collecting housing 10. The polishing blade 90 cuts or polishes the surface S1 of the hull 140 while being rotated in the second direction R2 by the motor 60 of the grinding unit 100.

While the polishing blade 90 cuts or polishes the surface S1 of the hull 140, the polishing blade 90 is in the fourth direction R4 and / or on the surface S1 of the hull 140. It can move along five directions R5. The fourth direction R4 and the fifth direction R5 may or may not be perpendicular to each other. In more detail, the fourth direction R4 and the fifth direction R5 may refer to all of the loci of the polishing blade 90, which may be generated in two-dimensional coordinates.

To this end, the rollers 44 are configured to freely move the dust collecting housing 10 on the surface S1 of the hull 140. That is, the rollers 44 increase the degree of freedom of movement of the dust collecting housing 10 on the surface S1 of the hull 140.

Referring to FIG. 8, while the polishing blade 90 cuts or polishes the surface S1 of the hull 140 of FIG. 7, the dust collecting fence 54 is in contact with the hull 140 and the hull 140. It is configured to limit the movement of byproducts resulting from grinding. The byproduct includes rust 145 of hull 140. In this case, the dust collecting fence 54 may surround the cutting guide opening 13 and thus limit the movement of the byproduct.

Therefore, the movement of the by-product does not occur between the dust collecting housing 10 and the hull 140 but only along the flow lines F1 and F2 passing through the internal space of the dust collecting housing 10. In other words, the by-products are not scattered towards the eyepiece. The by-product is moved to the dust collector of the reservoir 120 via the exhaust port 19 along the flow lines F1 and F2. The by-product accumulates in the dust collector of the reservoir 120.

Through this, the grinder 114 cuts or polishes the hull 140 to form a new surface S2 on the hull 140. After the new surface S2 is formed on the hull 140, the grinder 114 may be spaced apart from the hull 140 as shown in FIG. 7. Thus, the polishing blade 90 is spaced apart from the cutting guide opening 13. 6 to 8 disclose a method of using the grinder of the first embodiment of the present invention.

However, the grinder 114 of Figs. 6-8 can be replaced by the grinder 118 according to the second embodiment of the present invention. In addition, the grinding unit 110 of the grinders 114 and 118 may be replaced by the grinding unit 105 according to the third embodiment of the present invention.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
