본 고안은 연마기나 혹은 직선운동의 공구류에 사용되는 손 공구용 연마기에 관한 것이다.The present invention relates to a grinding machine for a hand tool used for a grinding machine or tools of linear motion.
특히, 모터의 동력을 받는 회전기의 어댑터를 소켓부에 끼워서 플러그와 결속시킴에 따라 회전력을 전달받는 회전축이 작동부재를 전, 후 왕복운동할 수 있도록 함으로써 헤드부로 돌출되는 고정봉에 연마숫돌등을 부착하여 사출금형등의 코너 부분이나 특정부분을 손쉽게 연마할 수 있는 것이다.In particular, by inserting the adapter of the rotor powered by the motor into the socket and engaging the plug, the rotary shaft receiving the rotational force can reciprocate the operating member before and after, so that the grinding wheel etc. protrude into the head. By attaching it, you can easily grind corners or specific parts of injection molds.
종래 일반적인 손 공구용 연마기는 단순히 모터작동에 의해 회전운동하는 회전축에 곧바로 연마숫돌등을 부착하였기 때문에 회전축과 동시에 회전운동하는 연마숫돌이 사출금형등의 코너부분이나 특정부분을 연마할수 없을 뿐만 아니라 연마할 수 있는 부분이 극히 제한되어 있어 불편함과 번거로움등으로 생산능률을 저하시키고 품질의 정밀도를 저하시켜 불량율이 상승되는 등의 많은 문제점이 발생되었다.Conventionally, the general hand tool grinder simply attaches a grinding wheel or the like directly to a rotating shaft that is rotated by a motor operation, so that the grinding wheel that rotates simultaneously with the rotating shaft cannot polish corners or specific parts such as injection molds. Due to the extremely limited parts, many problems such as deterioration of production efficiency due to inconvenience and hassle, deterioration of quality precision, and increase of defective rate have occurred.
본 고안은 이와같은 문제점을 감안하여, 회전운동하는 회전축에 직선운동하는 작동부재를 연재시켜 연마숫돌이 전, 후 왕복운동하도록 손 공구용 연마기를 안출한 것으로, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above problems, by extending the operating member in the linear motion to the rotary shaft to rotate the grinding wheel for hand tools to reciprocate before and after the grinding wheel, it will be described in detail by the accompanying drawings As follows.
중공체인 본체(1)의 내부에 안내홈(1')을 길이방향으로 형성하고 본체(1)의 전, 후단에 각기 헤드부(2)와 소켓부(3)를 형성한 결합수단에, 회전축(4)의 중앙에 "S"폭의 경사각(α°)을 갖는 작동홈(5)을 형성하고, 후측에는 키이홈(6)을 갖는 플러그(7)를 일체 형성한 회전수단과, 작동부재(8)의 선단에 고정봉(9)과 중앙에 돌턱(10)을 일체로 형성한 전, 후 작동수단을 상기 본체(1)의 내부로 삽입되도록 회전축(4)의 작동홈(5)에 돌턱(10)을 위치시킴과 동시에 작동부재(8)가 안내홈(1')에 삽입되고 고정봉(9)이 헤드부(2)로 돌출되어 전, 후 왕복운동하도록 하여서 되는 것이다.In the coupling means formed with the guide groove (1 ') in the longitudinal direction inside the main body (1) of the hollow body and the head portion (2) and the socket portion (3), respectively, before and after the main body 1, the rotating shaft A rotating means in which an actuating groove 5 having an inclination angle α ° of an “S” width is formed in the center of (4), and a plug 7 integrally formed with a plug 7 having a key groove 6 at a rear side thereof; In the working groove 5 of the rotating shaft 4 so that the front and rear operating means are integrally formed with the fixed rod 9 at the front end of the head 8 and the rear end 10 is integrally formed in the main body 1. At the same time as the position of the jaw 10, the operating member 8 is inserted into the guide groove (1 ') and the fixed rod (9) is projected to the head portion 2 to be reciprocated before and after.

이와같이 구성되는 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention is configured as described as follows.
먼저 본체(1)와 헤드부(2) 및 소켓부(3)를 결합한 연마기를 사용하려면, 헤드부(2)로 돌출된 작동부재(8)의 고정봉(9)에 별도의 연마숫돌(도면에 도시하지 않음)을 부착하고 소켓부(3)에는 별도의 회전기(15)를 끼우면 되는데, 이때 회전기(15)가 소켓부(3)의 삽입공(3')에 끼워짐과 동시에 회전축(4)의 후단에 형성된 플러그(7)에 끼워지면서 상호 키이홈(6)과 키이에 의해 결속되는 것이고, 또한 소켓부(3)의 외부에는 회전축(4)과 연결된 어댑터(14)가 소켓부(3)의 외주연으로 삽입되면 비로소 연마기를 사용할 수 있는 것이다.First, in order to use the grinder which combined the main body 1, the head part 2, and the socket part 3, a separate grinding wheel (figure 1) to the fixing rod 9 of the operation member 8 which protrudes into the head part 2 is used. (Not shown) and a separate rotor 15 may be inserted into the socket part 3, in which the rotor 15 is fitted into the insertion hole 3 ′ of the socket part 3 and at the same time the rotary shaft 4 (2) is fitted to the plug (7) formed at the rear end of the () and is bound by the mutual key groove (6) and the key, and also the adapter (14) connected to the rotary shaft (4) outside the socket portion (3) If it is inserted into the outer periphery of), the grinder can be used.
또한, 상기와 같이 헤드부(2)와 소켓부(3)로 연마숫돌과 회전력을 공급받게끔 회전기(15)를 설치하고 나면, 작업자는 회전기(15)에 설치된 온, 오프 스위치(도면에 도시하지 않음)를 온 시키면 되는데, 이때 회전기(15)에 의해 회전력을 전달받는 플러그(7)은 회전축(4)을 회전시키고, 회전축(4)은 작동부재(8)를 전, 후 운동하게끔 하는 것으로, 이러한 연계작동은 회전축(4)에 형성된 작동홈(5)과 작동부재(8)에 돌턱(10)이 상호 맞물려 있기 때문에 가능한 것이고, 또한 작동부재(8)가 전, 후 운동할 수 있도록 한 것은 작동부재(8)가 본체(1)의 안내홈(1')에 삽입되어 있기 때문인 것이다.In addition, after installing the rotor 15 to receive the grinding wheel and the rotational force to the head portion 2 and the socket portion 3 as described above, the operator is installed on the on-off switch (shown in the drawing) The plug 7 receiving the rotational force by the rotor 15 rotates the rotary shaft 4, and the rotary shaft 4 causes the operating member 8 to move forward and backward. This linkage operation is possible because the projection 10 is engaged with the operation groove 5 and the operation member 8 formed in the rotational shaft 4, and also allows the operation member 8 to move forward and backward. This is because the operating member 8 is inserted into the guide groove 1 ′ of the main body 1.
한편, 작동부재(8)의 전, 후 왕복운동량을 높일려면 먼저 회전축(4)에 형성된 작동홈(5)의 경사각(α°)을 최대한으로 크게하면 되는 것이다. 즉 작동홈(5)의 "S"폭을 넓히면 된다.On the other hand, in order to increase the amount of reciprocating motion before and after the operating member 8, the inclination angle (α) of the operating groove 5 formed on the rotary shaft 4 is to be made as large as possible. That is, the width of the "S" of the operation groove 5 may be widened.
이상과 같이 본 고안은 간단한 구조와 간편한 작동에 의해 누구나 손쉽게 사용할 수 있으며, 또한 사출금형등의 코너부분이나 혹은 특정부분을 일정하게 연마할 수 있음은 물론 생산성 향상으로 인해 정밀부품을 충족시킬 수 있는 매우 실용적인 고안인 것이다.As described above, the present invention can be easily used by anyone by a simple structure and simple operation, and also can regularly polish corners or specific parts such as injection molds, and can meet precision parts by improving productivity. It is a very practical design.
