[문헌 1] 한국 실용신안등록 제0398935호, 2005.10.10[Document 1] Korea Utility Model Registration No. 0398935, 2005.10.10

그라인더용 연마 휠은 금속표면을 가공하거나, 용접부를 다듬거나, 금속의 부식된 표면을 제거하는 등 산업 현장에서 광범위하게 사용되고 있다. 이와 같은 연마 휠은 고속으로 회전되는 그라인더에 고정되어 사용되고, 연마용 숫돌이나 샌드페이퍼로 구성된다.Grinding wheels for grinders are widely used in the industrial field, such as machining the metal surface, polish the weld, or remove the corroded surface of the metal. Such a polishing wheel is fixed to a grinder which is rotated at a high speed, and is used as a grinding wheel or sandpaper.

문헌 1 및 이와 유사한 통상적인 종래의 연마 휠은, 중심관에 끼워져 고정되는 지지관체에 다수개의 샌드페이퍼가 방사상으로 수직으로 연접되게 고정되는 구조를 가진다.Document 1 and similar conventional grinding wheels have a structure in which a plurality of sand papers are radially and vertically connected to a support tube body fitted into and fixed to a center tube.

그러나 이와 같은 연마 휠은 다수장의 샌드페이퍼가 연접되어 적층되는 구조이고, 또한 하나의 원통형과 같은 형상으로 되어 있어, 각각의 용도에 따라 그 크기를 달리하여 제조되어야 한다. 즉, 연마면의 넓이에 따라 이에 적합한 연마 휠의 높이를 가지는 것을 선택하여 사용하여야 하므로, 다양한 크기의 완제품으로서의 연마 휠이 구비되어야 하는 불편함이 있다.However, such a polishing wheel has a structure in which a plurality of sandpapers are connected and laminated, and also has a shape such as one cylindrical shape, and should be manufactured by varying the size according to each use. That is, since it is necessary to select and use a height of the polishing wheel suitable for this according to the width of the polishing surface, there is an inconvenience that the polishing wheel as a finished product of various sizes should be provided.

또한, 하나의 통체로 구성된 휠의 사용으로 인하여 휠 사포 전체가 연마면에 접촉되어 작용을 하므로, 연마면에서 발생된 분진 등이 사포에 융착되고 발생된 열을 제대로 식힐 수 없어 연마 효율이 떨어졌다. 즉, 종래는 하나의 사포와 인접된 다른 사포의 작용이 연마면 전체를 동시에 덮어 연마를 행하게 되어 통기가 어려워 열을 내리거나 분진을 제거하기가 어려워 분진이 사포면에 융착되어 연마 효율을 저하시켰다.In addition, since the entire wheel sandpaper is in contact with the polishing surface due to the use of one cylindrical wheel, dust generated from the polishing surface is fused to the sandpaper, and the generated heat cannot be cooled properly. . That is, in the related art, the action of one sandpaper and another sandpaper adjacent to the entire surface is polished at the same time, so that the ventilation is difficult, so that it is difficult to lower heat or remove dust, and the dust is fused to the sandpaper surface, thereby reducing the polishing efficiency. .

본 발명은 일정 높이를 가진 사포를 다수장 적층시킨 사포다발을 지지관체에 등간격으로 부착하여 하나의 단위휠을 형성시켜, 연마할 면적에 따라 상기 단위휠의 다수개를 중심관에 끼워 적당한 높이를 가지도록 할 수 있고, 디수개의 단위휠을 중심관에 끼울 때, 일정 각도만큼 돌려서 설치함으로써, 연마면에 작용하는 사포가 전체면에 동시에 작용하지 않고 회전에 따라 순차적으로 작용할 수 있도록 하여, 통기성과 배출성을 높여 연마 효율을 증대시키는 구조를 제공함에 목적이 있다.The present invention is attached to the support pipe body at equal intervals by stacking a plurality of sandpaper having a predetermined number of sandpaper having a certain height to form a single unit wheel, by inserting a plurality of the unit wheel in the center tube according to the area to be polished to a suitable height When inserting the number of unit wheels to the center tube, by rotating the fixed angle by a certain angle, sandpaper acting on the polishing surface can act sequentially according to rotation without acting on the entire surface at the same time. It is an object of the present invention to provide a structure that increases the over-exhaustability and increases the polishing efficiency.

사포가 설치된 단위휠을 일정한 각도로 회전시켜 중심관에 삽입하는 구조를 제공함으로써, 단위휠의 갯수에 따라 연마면에 가장 적합한 크기의 휠을 쉽게 형성시켜 사용할 수 있고, 사포가 일정 간격으로 회전되어 있으므로, 연마면에서 순차적으로 작용하여 분진 배출이 용이하고 냉각의 성능이 좋아 분진이 사포면에 융착되는 것이 방지되어 연마 효율이 증대되고 내구 수명이 증대되는 효과가 있다.By providing the structure of inserting the unit wheel installed with sandpaper into the center pipe by rotating it at a certain angle, it is possible to easily form the wheel of the most suitable size for the polishing surface according to the number of unit wheels, and the sandpaper is rotated at regular intervals. Therefore, it is possible to sequentially act on the polishing surface to facilitate dust discharge and good cooling performance to prevent the dust from being fused to the sandpaper surface, thereby increasing the polishing efficiency and the endurance life.

본 발명의 연마 휠(100)은 연마 기능을 행하는 단위휠(50) 다수개가 중심관(60)에 순차적으로 일정 각도만큼씩 회전되어 삽입고정됨을 특징으로 한다.The polishing wheel 100 of the present invention is characterized in that a plurality of unit wheels 50 for performing a polishing function are rotated and inserted and fixed by a predetermined angle in the center tube 60 sequentially.

상기의 단위휠(50)은 다수장의 사포가 적층된 사포다발(1); 원통체의 고리부(2a) 외주면에 다수개의 스페이서돌기(3a)가 등간격으로 형성되어 그 사이에 사포삽입홈(4a)이 형성되고, 상기 스페이스돌기(5a)의 상하부는 고리부(2a)보다 돌출되게 형성된 제1지지관체(70); 원통체의 고리부(2b) 외주면에 다수개의 스페이서돌기(3b)가 등간격으로 형성되어 그 사이에 사포삽입홈(4b)이 형성되고, 고리부(2b)의 내측면에 다수개의 접착제홈(6)이 형성되며, 스페이스돌기(5b)의 일측면에 링삽입홈(7)이 형성되어, 상기 제1지지관체(70)의 상하부에 링삽입홈(7)이 외측으로 표출되게 각각 설치되는 제2지지관체(80);를 포함하여 구성된다.The unit wheel 50 is a sandpaper bundle (1) in which a plurality of sandpaper is stacked; A plurality of spacer protrusions 3a are formed at equal intervals on the outer circumferential surface of the annular portion 2a of the cylindrical body, and sandpaper insertion grooves 4a are formed therebetween, and the upper and lower portions of the space protrusion 5a are annular portions 2a. A first support tube 70 formed to protrude more; A plurality of spacer projections 3b are formed at equal intervals on the outer circumferential surface of the annular portion 2b of the cylindrical body, and a sandpaper insertion groove 4b is formed therebetween, and a plurality of adhesive grooves ( 6) is formed, the ring insertion groove 7 is formed on one side of the space projection (5b), the ring insertion groove (7) is respectively installed so that the upper and lower portions of the first support pipe 70 to be expressed to the outside It is configured to include a second support tube (80).

따라서 연마 휠을 구성하기 위하여 다수개의 단위휠(50)이 적층되는 경우에는 단위휠(50)의 상하면에 형성된 링삽입홈(7)에 고정링(8)이 삽입되고, 링삽입홈(7)과 고정링(8)의 단면은 반원형이 바람직하다.Therefore, when a plurality of unit wheels 50 are stacked to form a polishing wheel, the fixing ring 8 is inserted into the ring insertion groove 7 formed on the upper and lower surfaces of the unit wheel 50, and the ring insertion groove 7 The cross section of the holding ring 8 is preferably semicircular.

이와 같이 본 발명은 단위휠(50)을 적정 갯수 만큼 중심관(60)에 끼워 제조할 수 있고, 현장에서 끼워 사용할 수도 있다.As described above, the present invention can be manufactured by fitting the unit wheel 50 to the center tube 60 by an appropriate number, and can also be used in the field.

우선, 사포다발(1)을 제1지지관체(70) 및 제2지지관체(80)에 접착제로 고정하기 위한 구조는 제1지지관체(70)의 고리부(2a)보다 스페이스돌기(5a)가 상하로 더 돌출된 구조와, 제2지지관체(80)의 접착제홈(6)이 제2지지관체(80)의 사포삽입홈(4a)의 내측으로 더 깊게 형성됨으로써 가능하다.First, the structure for fixing the sandpaper bundle 1 to the first support pipe 70 and the second support pipe 80 with an adhesive is larger than that of the loop portion 2a of the first support pipe 70. The structure further protrudes up and down, and the adhesive groove 6 of the second support tube 80 is formed deeper into the sandpaper insertion groove 4a of the second support tube 80.

즉, 제1지지관체(70)와 제2지지관체(80)를 적층하고, 사포삽입홈(4a)과 사포삽입홈(4b)이 서로 연결되게 한 후, 이에 사포다발(1)을 끼운다. 그리고 제2지지관체(80)의 고리부(2b)에 형성된 접착제홈(6)으로 접착제를 주입하게 되면, 도 7에 도시된 바와 같이 접착제통로(90)가 형성된다. 도 7은 도 6의 상부에서 본 것이고, 실선은 제2지지관체(80)의 외형이고, 점선은 은선을 표시한 것이 아니라 제1지지관체(70)의 외형을 표시한 것이다.That is, the first support pipe 70 and the second support pipe 80 are stacked, and the sandpaper insertion groove 4a and the sandpaper insertion groove 4b are connected to each other, and then the sandpaper bundle 1 is fitted thereto. And when the adhesive is injected into the adhesive groove 6 formed in the ring portion (2b) of the second support tube 80, the adhesive passage 90 is formed as shown in FIG. FIG. 7 is a view from the top of FIG. 6, and the solid line is the outline of the second support tube 80, and the dotted line shows the outline of the first support tube 70 rather than the hidden line.

따라서 도 8과 같이 접착제는 접착제홈(6)을 통해 아래의 접착제통로(90)를 통해 하부로 이동되고, 둘레를 따라 이동되어 사포다발(1)을 고정시키게 된다.Therefore, as shown in FIG. 8, the adhesive moves downward through the adhesive groove 90 through the adhesive groove 6, and moves along the circumference to fix the sandpaper bundle 1.

위와 같이 하나의 단위휠(50)이 완성되면, 이를 다수개 중심관(60)에 끼워 사용하면 된다. 특히 단위휠(50)을 중심관(60)에 끼울 때는 도 1과 같이 일정 각도씩 회전되게 하여, 사포다발(1)이 순차적으로 연마면에 작용하도록 한다.When one unit wheel 50 is completed as described above, it may be used by inserting it into a plurality of central pipes (60). Particularly, when the unit wheel 50 is inserted into the center tube 60, it rotates by a predetermined angle as shown in FIG. 1, so that the sandpaper bundle 1 sequentially acts on the polishing surface.

그리고 도 3의 단면도와 같이, 다수개의 단위휠(50)을 적층할 경우에는 단위휠(50)을 구성하는 상하의 제2지지관체(80)의 외측으로 형성된 링삽입홈(7)에 고정링(8)을 삽입하여 보다 견고한 체결이 이루어지도록 한다. 고정링(8)은 그 단면이 반원형이 바람직하나 어떠한 형태라도 가능하다. 그리고 중심관(60)의 상부에 마지막으로 삽입된 단위휠(50)의 제2지지관체(80)의 상부와, 중심관(60)의 하부에 마지막으로 삽입된 단위휠(50)의 제2지지관체(80)의 하부에는 캡(9)을 설치하여 고정한다.And, as shown in the cross-sectional view of Figure 3, in the case of stacking a plurality of unit wheels 50 fixed ring in the ring insertion groove (7) formed on the outside of the upper and lower second support pipe body 80 constituting the unit wheel 50 ( Insert 8) to make a tighter connection. The fixed ring 8 is preferably semicircular in cross section, but may be in any form. And a second upper portion of the second support tube body 80 of the unit wheel 50 finally inserted into the upper portion of the center tube 60 and a second portion of the unit wheel 50 finally inserted into the lower portion of the center tube 60. The cap 9 is installed and fixed to the lower portion of the support tube 80.

상기와 같이 연마 휠(100)이 완성되면, 그라인더의 회전축에 중심관(60)을 체결하여 사용하면 되고, 연마면에 사포가 접촉되게 사용한다. 이 때 본 발명은 회전되면서, 사포다발(1)의 사포가 연마 작용을 하게 되고, 사포다발(1)이 순차적으로 일정 각도 회전되어 설치되어 있으므로, 연마면 전체를 사포가 덮지 않게 된다.When the polishing wheel 100 is completed as described above, the center tube 60 may be fastened to the rotating shaft of the grinder to be used, and sandpaper may be used in contact with the polishing surface. At this time, while the present invention is rotated, the sandpaper of the sandpaper bundle 1 has a polishing action, and the sandpaper bundle 1 is sequentially rotated by a predetermined angle, so that the sandpaper does not cover the entire polishing surface.

따라서 연마중에는 통기가 잘 되어 냉각의 효과가 달성되고, 분진 또한 외부로 용이하게 제거되어, 연마면이 고온에 의해 이물질 등이 융착되는 것과, 사포면 에 이물질이 융착되는 것이 방지되므로, 연마 효율의 증대와 사포의 수명이 증대되게 된다.Therefore, during polishing, the ventilation effect is good and cooling is achieved, and dust is also easily removed to the outside, so that foreign matters such as the polishing surface are prevented from being fused by high temperature, and foreign matters are prevented from being fused to the sandpaper surface. The increase and the lifespan of sandpaper will increase.
