그라인더휠용 흔들림방지 원터치 커플러{A One Touch Coupler for Grinder Wheek of Anti-shake}A One Touch Coupler for Grinder Wheek of Anti-shake}

본 발명은 그라인더휠용 흔들림방지 원터치 커플러에 관한 것으로서, 보다 상세하게는 그라인더에 체결되는 탄력안착를 구비하여 적은힘으로도 신속하고 안전하게 체결할 수 있고, 상기 안착몸통의 상측에 그라인더의 회전력과 역회전되는 나비체결부를 구비하여 그라인더휠을 더욱 안전하게 체결하여 사용할 수 있을 뿐만 아니라 그라인더훨이 이탈되는 것을 미연에 방지되어 안심하고 사용할 수 있고, 다수개의 나비날개가 형성된 나비체결부를 구비하여 그라인더에 그라인더휠을 누구나 용이하게 체결할 수 있는 그라인더휠용 흔들림방지 원터치 커플러에 관한 것이다.The present invention relates to an anti-shake one-touch coupler for a grinder wheel, and more particularly, it is provided with an elastic seat fastened to the grinder so that it can be quickly and safely fastened with little force, and is rotated in reverse to the rotational force of the grinder on the upper side of the seating body. Not only can the grinder wheel be more securely fastened and used with a butterfly joint, but it is also possible to use it with confidence because it prevents the grinder wheel from being dislodged in advance, and a butterfly joint with a number of butterfly wings is provided, so that anyone can use the grinder wheel in the grinder. It relates to an anti-shake one-touch coupler for a grinder wheel that can be easily fastened.

일반적으로, 디스크 그라인더는 일반적으로, 조선 및 각종 산업용 부품의 1차 가공이 완료된 후 미처 가공이 덜된 부분이나 거친 표면, 혹은 도장을 행하기 전에 2차 가공을 필요로 하는 경우에 표면을 매끄럽게 하기 위하여 사용되고, 또한 용접 후 사상처리 작업용으로 사용되는 것으로, 대형 부품이나 고도의 정밀도를 요하는 경우에는 연삭숫돌을 고속으로 회전시켜 대상물을 정밀하게 다듬는 연삭기를 사용하게 되고, 소형 또는 고도의 정밀도를 요하지 않는부품일 경우에는 주로 가볍고 사용이 간편한 핸드 디스크 그라인더를 이용하여 대상물의 표면을 다듬질하는 작업을 행하게 된다.In general, disk grinders are generally used in order to smooth the surface when the primary processing of shipbuilding and various industrial parts is completed, and in the case of a part that has not yet been processed or a rough surface, or when secondary processing is required before painting. It is also used for finishing processing after welding, and when large parts or high precision are required, a grinding machine is used that precisely polishes the object by rotating the grinding wheel at high speed, and does not require small or high precision. In the case of parts, the work of finishing the surface of the object is mainly performed using a light and easy-to-use hand disc grinder.

이러한, 핸드 디스크 그라인더는 전기 또는 에어로 작동이 이루어지는 한편 회전축을 고속으로 작동시킴과 동시에 이 회전축에 각종 그라인더휠(절단석, 옵셋트, 연마석, 디스크페이퍼, 디스크 휠 페이퍼, 컵브러시, 원형 브러시)를 장착하여 연마 대상물의 표면을 연마하게 되는 것으로, 이러한, 그라인더휠은 소모성 부품이기 때문에 마모 상태에서 따라 새것으로 교체하여 사용하게 된다.Such a hand disc grinder operates by electric or aero operation while operating the rotating shaft at high speed, and at the same time, various grinder wheels (cutting stone, offset, grinding stone, disc paper, disc wheel paper, cup brush, circular brush) are installed on the rotating shaft. It is installed to polish the surface of the object to be polished, and since such a grinder wheel is a consumable part, it is replaced with a new one depending on the condition of wear.

핸드 디스크 그라인더에 대표적으로 사용되는 그라인더휠을 교체하기 위해서는 디스크 그라인더의 회전축에 표준 부속공구인 전용 공구를 이용하여 풀어준 다음, 새로운 그라인더휠를 회전축에 끼운 후 전용공구로 고정시키게 된다.In order to replace the grinder wheel typically used in hand disc grinders, loosen the disc grinder's rotating shaft with a dedicated tool, which is a standard accessory, and then insert the new grinder wheel into the rotating shaft and fix it with a dedicated tool.

이와같이 그라인더휠을 교체하기위하여 작업 현장에서 전용스패너를 이용하여 그라인더휠를 교체하여야 하므로 매우 번거로운 작업이 될 수 밖에 없다.In order to replace the grinder wheel in this way, it is inevitable to be a very cumbersome operation because the grinder wheel must be replaced using a dedicated spanner at the work site.

이러한 문제점을 해결하기 위하여 그라인더에 그라인더휠을 전용스페너를 사용하지 않고 체결할 수 있는 기술이 개발되어 공개되어 있다.In order to solve this problem, a technology for fastening a grinder wheel to a grinder without using a dedicated spanner has been developed and disclosed.

상기 그라인더휠을 그라인더에 간편하게 체결할 수 있는 국내 특허 10-1483963호 기술이 공개되어 있으며, 도 6에 도시된 바와 같이, 공개된 "그라인더의 연마디스크 체결장치"는 핸드 디스크 그라인더(10)의 회전축(11)에 형성된 받침턱(11a)에 받쳐지게 회전수단(50)을 끼우되 상기 회전축(11)은 회전수단(50)에서 돌출되게 하고, 상기 회전수단(50)은 지지체(60)가 회전체(70)에 끼워진 채로 이탈되지 않게 결합되는 한편 상기 지지체(60)와 회전체(70) 사이에는 스러스트 베어링(80)을 설치하고, 상기 회전수단(50)을 구성하는 지지체(60)는 회전축(11)의 받침턱(11a)에 받쳐지는 한편 상기 지지체(60)와 대칭된 위치의 회전체(70)에는 연마디스크(20)가 회전축(11)에 나사 결합되면서 밀착되게 하고, 상기 회전축(11)에 끼워지는 연마디스크(20)는 중앙에 형성된 결합링(30)의 나사부(31)가 회전축(11)에 나사 결합되면서 회전수단(50)을 압착하며 결합된 것을 특징으로 하고 있다.Korean patent No. 10-1483963 technology for easily fastening the grinder wheel to the grinder is disclosed, and as shown in FIG. 6, the disclosed "abrasive disk fastening device of a grinder" is a rotating shaft of the hand disk grinder 10 Insert the rotation means 50 to be supported by the support jaw (11a) formed in (11), but the rotation shaft 11 protrudes from the rotation means 50, and the rotation means 50 has the support 60 rotating. Meanwhile, a thrust bearing 80 is installed between the support 60 and the rotating body 70 while being fitted in the entire 70 and the support 60 constituting the rotating means 50 is a rotating shaft While being supported by the support jaw (11a) of (11), the polishing disk (20) is screwed to the rotation shaft (11) and in close contact with the rotation body (70) in a position symmetrical to the support body (60), and the rotation shaft ( The polishing disk 20 fitted to 11) is characterized in that the threaded portion 31 of the coupling ring 30 formed in the center is screwed to the rotation shaft 11 while compressing the rotating means 50 to be coupled.

그러나, 상기 종래기술은 회전축에 고정된 체결장치에 직접 체결할 수 있도록 하고 있으나, 이 경우, 체결장치의 복잡함과 체결과정의 어려움으로 인하여, 작업자가 빠른 시간에 간편하게 교체작업을 할 수 없음은 물론 핸드 디스크 그라인더의 회전축에 별도의 체결장치를 설치하기 때문에 기존의 핸드 디스크 그라인더에는 적용하기 곤란한 문제점이 있었다.However, the prior art allows direct fastening to the fastening device fixed to the rotating shaft, but in this case, due to the complexity of the fastening device and the difficulty of the fastening process, the operator cannot easily perform replacement work in a short time. Since a separate fastening device is installed on the rotating shaft of the hand disk grinder, there is a problem that it is difficult to apply to the existing hand disk grinder.

또한, 상기 종래기술은 체결시 별도의 도구가 불필요하나 회전체에 연결되어 지지체의 사이에 스러스트베어링으로 고속회전시 흔들림이 발생하여 고속사용이 곤란하고, 체결시 바란스가 잘 잡힙지 않는 문제점도 있었으며, 회전수단과 지지체가 일체로 결합되기 곤란한 문제점도 있었다.In addition, the prior art does not require a separate tool during fastening, but it is connected to a rotating body and shakes during high-speed rotation with a thrust bearing between the supports, making it difficult to use at high speed, and there is a problem that the balance is not well held during fastening. There is also a problem in that it is difficult to integrally combine the rotating means and the support.

본 발명은 상기와 같은 문제점을 해결하기 위해서 안출된 것으로서, 본 발명의 목적은 그라인더의 회전축에 안착되는 안착몸통을 구비하여 적은힘으로도 신속하고 용이하게 체결할 수 있고, 그라인더의 회전력과 역회전되는 다수개의 나비날개가 형성된 나비체결부를 구비하여 그라인더에 그라인더휠을 더욱 안전하게 사용할 수 있으며, 그라인더휠이 곡면경사부를 따라 나비체결부에 용이하게 삽입되어 편리하게 그라인더휠을 체결할 수 있고, 그라인더휠이 경사진 경사배출부를 따라 상기 절개안착부에서 용이하게 분리할 수 있으며, 안착몸통과 나비체결부의 사이에 깔데기 형상의 탄력안착부를 구비하여 그라인더휠이 회전축에 탄력적으로 안착되면서 상호 완벽하게 밀착되어 그라인더휠을 그라인더에 안전하게 체결할 수 있고, 그라인더휠의 회전방향과 반대방향으로 회전되어 그라인더 휠이 이탈되는 것을 방지할 수 있는 그라인더휠용 흔들림방지 원터치 커플러를 제공하는데 그 목적이 있다. The present invention has been conceived to solve the above problems, and an object of the present invention is to provide a seating body that is seated on the rotary shaft of the grinder so that it can be quickly and easily fastened with little force, and the rotational force and reverse rotation of the grinder The grinder wheel can be used more safely in the grinder by having a butterfly joint with a plurality of butterfly wings that are formed, and the grinder wheel is easily inserted into the butterfly joint along the curved slope, so that the grinder wheel can be conveniently fastened.
