연마휠{Grinding wheel}Grinding Wheel

본 고안은 샌드페이퍼가 방사상으로 돌아가며 중첩되도록 부착된 연마휠에 관한 것으로서, 보다 상세하게는 샌드페이퍼의 일측부에 접착부가 일체로 형성되고, 어느 한 샌드페이퍼의 접착부에 중첩되는 샌드페이퍼의 접착부가 겹쳐지도록 부착되는 연마휠에 관한 것이다.The present invention relates to a polishing wheel attached so that the sand paper is radially overlapping, and more specifically, an adhesive part is integrally formed at one side of the sand paper, and the adhesive part of the sand paper overlapping the adhesive part of the sand paper is attached to overlap. It relates to a polishing wheel.

대한민국 특허 제460413호(2004년 11월 29일 등록)에 "샌드페이퍼제 연마휠"이 소개되어 있다.Korean paper No. 460413 (registered November 29, 2004) introduces a "sandpaper grinding wheel."

상기 샌드페이퍼제 연마휠은 사각형으로 재단한 동일 규격의 샌드페이퍼를 인접한 것끼리 겹쳐지도록 원주방향으로 배열한 샌드페이퍼 조합체를 허브 축에 꽂고, 허브에 에폭시수지 접착제로 샌드페이퍼 조합체를 고정되도록 구성한 것에 있어서, 가장자리의 절곡 부분에 톱니를 갖는 허브 플랜지상에 허브 축과 동심원상으로 환상의 샌드페이퍼 내측단 받이용 돌출받침을 형성한 것을 허브로 하고, 상기 돌출받침의 외곽에 형성되는 오목부에는 원주피치간격으로 주입공을 천공하며, 최대 직경이 돌출받침의 원경을 넘지 않게 형성하고 가장자리에는 톱니를 갖는 누름판을 상기 허브의 허브 축에 끼워서 허브 축에 끼워진 샌드페이퍼 조합체를 누르게 하며, 상기 누름판의 축관 선단으로 돌출된 허브 축의 단부를 버링 가공하여 누름판을 고정하고, 상기 허브 플랜지의 오목부에 천공된 주입공으로 에폭시수지 접착제를 주입하여 허브에 샌드페이퍼 조합체의 내측단 이면을 고정한다.The sandpaper polishing wheel comprises a sandpaper combination arranged in a circumferential direction such that sandpapers of the same size cut in squares are overlapped with each other on a hub axis, and the sandpaper combination is fixed to the hub by epoxy resin adhesive. The hub is formed by forming an annular sandpaper inner end receiving projection concentrically with the hub axis on the hub flange having teeth at the bent portion, and the recess formed at the outer side of the projection bearing has an injection hole at the circumferential pitch interval. Perforations, and the maximum diameter is formed so as not to exceed the diameter of the protruding base, and the pressing plate having a tooth at the edge is inserted into the hub shaft of the hub to press the sandpaper assembly fitted to the hub shaft, and the hub shaft protruding to the tip of the shaft tube of the pressing plate. Burring the end to fix the press plate, Injecting an injection into a ball epoxy resin adhesive in the recess of the drilling machine is fixed to the hub flange is the inner end of the hub combination sandpaper.

그러나, 상기 샌드페이퍼제 연마휠은 사각형으로 재단된 샌드페이퍼의 어느 한 꼭지점이 겹쳐지도록 샌드페이퍼가 중첩되어 원주방향으로 배열되기 때문에, 허브휠에 부착된 샌드페이퍼의 갯수가 적고, 샌드페이퍼가 허브휠와 수평하게 배치되어, 연마 작업을 할 때, 연마휠을 옆으로 기울여 연마해야 하고, 이와같은 연마방법은 샌드페이퍼가 피연삭물의 접촉하는 연마면적을 적게 하여 많은 연마작업을 요구하고, 연마휠의 어느 한 쪽 샌드페이샌드만이 피연삭물과 접촉되어 힘을 받기 때문에 샌드페이퍼가 허브휠에서 쉽게 탈락되는 단점이 있다.However, since the sandpaper polishing wheels are arranged in the circumferential direction by overlapping sandpapers so that any one vertex of the sandpaper cut in a square overlaps, the number of sandpapers attached to the hub wheels is small, and the sandpapers are arranged horizontally with the hub wheels. When polishing, the polishing wheel must be tilted to the side to polish, and this polishing method requires a lot of polishing work because the sandpaper reduces the polishing area in contact with the workpiece and the sandpaper sand on either side of the polishing wheel Since only the sand is forced to contact the workpiece, the sandpaper is easily removed from the hub wheel.

따라서, 본 고안의 목적은 샌드페이퍼의 일측부에 접착부가 일체로 형성되고, 어느 한 샌드페이퍼의 접착부에 중첩되는 샌드페이퍼의 접착부가 겹쳐지도록 부착됨으로서, 종래의 연마휠에 부착된 샌드페이퍼보다 많은 샌드페이퍼가 촘촘하게 배열되고, 접착부에 의해 허브휠이 지면에서 이격됨으로서, 연마작업시 연마휠을 어느 한 쪽으로 기울이지 않아도 되는 연마휠을 제공하는 것이다.Therefore, an object of the present invention is that the adhesive portion is integrally formed on one side of the sand paper, and attached to overlap the adhesive portion of the sand paper overlapping the adhesive portion of any one of the sand paper, so that more sand paper is densely arranged than the sand paper attached to the conventional grinding wheel. In addition, the hub wheel is separated from the ground by the adhesive portion, to provide a polishing wheel that does not have to tilt the polishing wheel to either side during the polishing operation.

상기와 같은 목적을 달성하기 위한 본 고안의 바람직한 실시예를 도면을 참조하여 상세하게 설명하기로 한다.Preferred embodiments of the present invention for achieving the above object will be described in detail with reference to the drawings.

도 1 및 도 2를 참조하면, 본 고안에 따른 연마휠은 사각형의 바디(12)와, 상기 바디(12)의 상단에 일체로 형성된 접착부(11)로 구성된 다수개의 샌드페이퍼(10)가 겹쳐져 중공부를 갖는 도넛 형상으로 형성되고, 이때, 다수개가 겹쳐진 접착부(11)에 의해 원형 장착부(25)가 형성되고, 바디부(12)에 의해 원형 연마부(20)가 형성되며, 상기 원형 장착부(25)에 허브휠(30)이 장착될 때, 허브휠(30)의 상부 캡(31) 및 하부 캡(33)이 에폭시수지 접착제(도시하지 않음)에 의해 접합된다.1 and 2, the polishing wheel according to the present invention is a hollow body by overlapping a plurality of sandpaper 10 consisting of a rectangular body 12, the adhesive portion 11 formed integrally on the upper end of the body 12 It is formed in a donut shape having a portion, wherein a circular mounting portion 25 is formed by a plurality of overlapping adhesive portion 11, a circular grinding portion 20 is formed by a body portion 12, the circular mounting portion 25 When the hub wheel 30 is mounted on the upper wheel 31 and the lower cap 33 of the hub wheel 30 are bonded by an epoxy resin adhesive (not shown).

상기 접착부(11)는 가로길이(S1)가 바디부(12)의 가로길이(S2)보다 짧게 형성된다. 이것에 의해, 샌드페이퍼의 접착부(11)가 중첩되어 연마휠이 도넛 형태로 형성될 때, 원형 장착부(25)가 원형 연마부(20)의 내측면(21)에 대해 단차지게 형성되어, 허브휠(30)이 원형 장착부(25)에 장착될 수 있다. The adhesive part 11 has a horizontal length S1 that is shorter than the horizontal length S2 of the body part 12. As a result, when the bonding portion 11 of the sand paper overlaps and the polishing wheel is formed in a donut shape, the circular mounting portion 25 is formed stepped with respect to the inner surface 21 of the circular polishing portion 20, so that the hub wheel 30 may be mounted to the circular mount 25.

도 3을 참조하면, 또한, 상기 샌드페이퍼(10)가 겹쳐져 배열되었을 때, 상기 샌드페이퍼(10)의 외측 모서리(13)가 바닥면(40)에 대하여 소정의 경사각(a)을 갖는다. 이것에 의해, 샌드페이퍼(10)의 바디부(12)에 의해 형성된 원형 연마부(20)는 바닥면(40)에서 8~12mm의 높이(h)를 가지며, 상기 연마부(20)의 높이(h)에 의해 허브휠(30)의 하부캡(33)이 바닥면(40)에 닿지 않게 된다.Referring to FIG. 3, when the sandpapers 10 are arranged to overlap each other, the outer edge 13 of the sandpaper 10 has a predetermined inclination angle a with respect to the bottom surface 40. Thereby, the circular grinding | polishing part 20 formed by the body part 12 of the sandpaper 10 has the height h of 8-12 mm in the bottom surface 40, and the height of the said grinding part 20 ( h) the lower cap 33 of the hub wheel 30 is not in contact with the bottom surface (40).

상기 경사각(a)은 30°~40°일 수 있으며, 35°가 바람직하다.The inclination angle (a) may be 30 ° ~ 40 °, preferably 35 °.

상기와 같이 구성된 본 고안에 따른 연마휠은 연마작업을 할 때, 원형 연마부(20)의 연마면(23) 전체가 바닥면(40)에 밀착되게 도 3에 도시된 것과 똑바로 배치하여 연마를 할 수 있어, 원형의 연마부(20)가 균일하게 바닥면(40)으로부터 반력을 받음으로써, 연마작업중에 연마면(23)이 위로 뒤집어지지 않으며, 샌드페이퍼(10)가 허브휠(30)에서 탈락되지 않으며, 피연삭물과 마찰되는 원형 연마부(20)의 연마면적이 넓어 연마작업을 단축할 수 있다.Polishing wheel according to the present invention configured as described above when the grinding operation, the polishing surface 23 of the circular polishing portion 20 is placed in close contact with the one shown in FIG. Since the circular polishing portion 20 receives the reaction force from the bottom surface 40 uniformly, the polishing surface 23 is not turned upside down during the polishing operation, and the sandpaper 10 is removed from the hub wheel 30. The polishing area of the circular polishing unit 20 which is not dropped and is rubbed with the workpiece may be widened, thereby shortening the polishing operation.

위에서 설명한 바와같이, 본 고안에 따른 연마휠은 연마작업중에 연마면이 위로 뒤집어지지 않으며, 샌드페이퍼가 허브휠에서 탈락되지 않으며, 피연삭물과 마찰되는 연마부의 연마면적이 넓어 연마작업을 단축할 수 있는 효과가 있다As described above, the polishing wheel according to the present invention does not turn upside down during the polishing operation, sand paper does not fall off from the hub wheel, and the polishing area of the polishing portion rubbed with the workpiece can be shortened.
