As shown in FIG. 3, the jig for manufacturing a cutting wheel according to the present invention has a plate shape and is spaced apart from the top surface of the core material 2 by a thickness of the cutting wheel so that the protrusion 12 protrudes downward and is formed in a “T” shape. The jig main body 10 and the rotating shaft 20 is fixed to one side of the jig main body 10 around the protrusion 12 and detachably fitted to the pawl 120, and the protrusion 12 The support member 30 is fixed to the other side of the jig main body 10, the lower end is supported on the upper end of the mold base 100.

여기에서 상기 돌출부(12)의 일측 모서리는 상기 폴(120)의 외주에 접촉되지 않고, 상기 돌출부(12)의 타측 모서리는 상기 몰드베이스(100)의 내주에 접촉되지 않도록 형성하여 몰드 내에서 지그본체(10)가 회전될 때, 몰드베이스(100)나 폴(120)에 의해 간섭되지 않도록 하기 위함이다.Here, one edge of the protrusion 12 does not contact the outer circumference of the pawl 120, and the other edge of the protrusion 12 is formed so as not to contact the inner circumference of the mold base 100, thereby jig in the mold. This is to prevent interference by the mold base 100 or the pole 120 when the main body 10 is rotated.

그리고 지그본체(10)에 수평으로 장공(14)이 형성되어 있으며, 이 장공(14)은 상기 회전축(20)이 지그본체(10)에 고정될 때, 회전축(20)의 수평위치를 조정하기 위한 것으로, 즉 커팅휠의 직경에 따라 회전축(20)이 고정되는 수평위치를 변경하기 위한 것이다. And the long hole 14 is formed horizontally in the jig body 10, the long hole 14 is to adjust the horizontal position of the rotating shaft 20 when the rotating shaft 20 is fixed to the jig body 10 To, that is, to change the horizontal position in which the rotating shaft 20 is fixed in accordance with the diameter of the cutting wheel.

또한, 상기 회전축(20)은 별도로 구비된 제1고정부(22)에 수직으로 이동가능하게 고정되고, 상기 제1고정부(22)에는 상기 장공(14)으로 관통되는 돌기부(22a)가 수평으로 형성되며, 이 돌기부(22a)에는 나사산이 형성되어 있어 별도의 체결부재(24)가 체결된다. 즉, 상기 회전축(20)을 제1고정부(22)에 고정한 후에, 상기 제1고정부(22)의 돌기부(22a)를 지그본체(10)의 장공(14)으로 통과시켜 제1고정부(22)를 상기 장공(14) 주변에 밀착시키고 상기 체결부재(24)를 돌기부(22a)에 체결함으로써 상기 회전축(20)을 지그본체(10)에 고정하는 것이다. 여기에서 상기 체결부재(24)는 작업자가 손으로 쉽게 잡고 체결할 수 있는 나비너트인 것이 바람직하다. In addition, the rotation shaft 20 is fixed to be movable vertically to the first fixing portion 22, which is provided separately, the projection 22a penetrating through the long hole 14 in the first fixing portion 22 is horizontal The protrusion 22a is formed with a screw thread to which a separate fastening member 24 is fastened. That is, after the rotation shaft 20 is fixed to the first fixing part 22, the protrusion part 22a of the first fixing part 22 passes through the long hole 14 of the jig body 10 to fix the first fixing part. The rotating shaft 20 is fixed to the jig main body 10 by close contact with the periphery of the long hole 14 and the fastening member 24 to the protrusion 22a. Here, the fastening member 24 is preferably a butterfly nut that can be fastened by the operator by hand.

또한, 상기 회전축(20)이 상기 제1고정부(22)에 고정되고, 별도의 너트(26)가 회전축(20)의 하단으로부터 체결되어 제1고정부(22)의 하단에 밀착된다. In addition, the rotation shaft 20 is fixed to the first fixing portion 22, a separate nut 26 is fastened from the lower end of the rotating shaft 20 is in close contact with the lower end of the first fixing portion 22.

그리고 상기 지그본체(10)에 제2고정부(32)가 돌출되게 설치되고, 상기 제2고정부(32)에 회전축(20)이 설치되어 상하 이동가능하게 고정된다. In addition, a second fixing part 32 is installed to protrude from the jig body 10, and a rotating shaft 20 is installed to the second fixing part 32 to be fixed to be movable up and down.

또한, 도 6에 도시된 바와 같이, 상기 지지부재(30)가 상기 제2고정부(32)에 상하 이동가능하게 고정될 때에는 너트(34)가 별도로 구비되어 상기 지지부재(30)의 하단으로부터 체결된 후에 상기 제2고정부(32)의 하단에 밀착된다. In addition, as shown in FIG. 6, when the support member 30 is fixed to the second fixing part 32 so as to be movable up and down, a nut 34 is provided separately from the lower end of the support member 30. After being fastened, it is in close contact with the lower end of the second fixing part 32.

본 발명에 의한 커팅힐 제조용 지그로 커팅휠을 제조하려면 먼저 도 4와 같이 지그를 몰드에 설치하기 전에 커팅휠의 두께에 따른 지그의 회전축(20)의 수평 및 수직위치를 설정해야 한다. In order to manufacture a cutting wheel with a jig for manufacturing a cutting hill according to the present invention, first, the horizontal and vertical positions of the rotary shaft 20 of the jig should be set according to the thickness of the cutting wheel before installing the jig in the mold as shown in FIG. 4.

즉, 회전축(20)의 수평위치는 커팅휠을 제작되는 몰드의 반경에 의해서 결정되는데, 몰드의 반경하고 지지부재(30)와 회전축(20) 사이의 거리를 같게 하려면 지지부재(30)가 고정되어 있기 때문에, 지그본체(10)에 회전축(20)을 고정하는 체결부재(24)를 약간 풀어서 회전축(20)을 수평으로 이동시켜서 지지부재(10)가 몰드의 몰드베이스(100) 상단에 지지되는 것을 확인하고 체결부재(24)를 다시 채워서 고정한다. That is, the horizontal position of the rotating shaft 20 is determined by the radius of the mold to make the cutting wheel, the support member 30 is fixed to equal the radius of the mold and the distance between the supporting member 30 and the rotating shaft 20 Since the fastening member 24 which fixes the rotating shaft 20 to the jig body 10 is slightly loosened, the rotating shaft 20 is moved horizontally so that the supporting member 10 is supported on the mold base 100 of the mold. After confirming that the fastening member 24 is refilled and fixed.

회전축(20)의 수직위치는 회전축(20)의 체결된 너트(26)를 풀어서 제1고정부(22)에 체결된 회전축(20)을 풀어서 상하 이동시켜 높이를 정한 후에, 너트(26)를 다시 채워서 제1고정부(22)의 하단에 밀착시킨다. The vertical position of the rotating shaft 20 is determined by unscrewing the fastening nut 26 of the rotating shaft 20 by releasing the rotating shaft 20 fastened to the first fixing part 22 to move up and down to determine the height. Refill and close to the bottom of the first fixing part 22.

이렇게 지그의 세팅이 완료되면, 회전 작업대에 하부몰드(110)를 올려놓고, 하부몰드(110)의 관통구멍(110a)에 폴(120)을 끼운 후에 상기 하부몰드(110) 상부면에 심재(2)를 올리고, 하부몰드(110)의 외주로 몰드베이스(100)를 끼운다. 그런 다음, 상기 심재(2)의 상부면에 분말형 세라믹 배합물(3)을 올리고 지그의 회전축(20)을 폴(120)에 끼우면서 지지부재(30)는 몰드베이스(100)의 상단부에 지지시킨 다음, 회전 작업대를 회전시키면 심재(2) 상부면에 올려진 배합물(3)이 상기 돌출부(12)에 의해 고르게 펼쳐지게 되는 것이다. 이때 몰드는 작업대에 의해 회전되지만 지그는 작업자가 손으로 잡고 회전되지 않도록 한다. When the setting of the jig is completed, the lower mold 110 is placed on the rotary workbench, the pole 120 is inserted into the through hole 110a of the lower mold 110, and the core material (the upper surface of the lower mold 110) 2) raise the mold base 100 into the outer circumference of the lower mold 110. Then, the powdered ceramic compound 3 is placed on the upper surface of the core 2 and the support member 30 is supported at the upper end of the mold base 100 while inserting the rotary shaft 20 of the jig into the pole 120. After rotating the rotary workbench, the compound 3 placed on the upper surface of the core material 2 is evenly spread by the protrusion 12. At this time, the mold is rotated by the workbench, but the jig is held by the worker by hand so as not to rotate.
