본 고안은 주로 콘크리트를 치기 위하여 설치되는 거푸집의 구멍을 뚫는데 사용되는 연마판을 부설한 전기드릴에 관한 것으로서, 본 고안의 특징은, 전기드릴의 드릴척(DRILL CHUCK)부분에다 연마판을 고정한 구조로 구성함으로서 작업중 드릴의 날이 손상되었을 경우 척에서 드릴을 분리하여 드릴날을 간단히 연마하여 사용할 수 있도록 한데 있다.The present invention mainly relates to an electric drill in which an abrasive plate is used to drill a hole of a formwork installed to strike concrete. A feature of the present invention is a structure in which an abrasive plate is fixed to a drill chuck (DRILL CHUCK) part of an electric drill. When the drill blade is damaged during the operation, the drill blade can be removed and used to simply grind the drill blade.

토건구조물은 철근을 배열한 좌우 양측에 거푸집을 설치하여 콘크리트를 치게되는 바, 콘크리트를 치기전 콘크리트의 압력에 의하여 좌우 거푸집이 벌어지는 것을 방지하기 위하여 드릴로 좌, 우거푸집에 구멍을 뚫어 철선등으로 좌, 우거푸집을 견고히 묶게 되는데, 이때 좌우 거푸집의 사이에 배열된 철근은 외부에서 볼수 없으므로 거푸집의 적당한 곳에 드릴로 구멍을 뚫을 시 드릴날이 상기의 철근에 접촉되어 쉽게 손상되게 되었으며, 손상된 드릴은 새것으로 교체 사용하게 되었다.Construction structures are formed by placing the formwork on both sides of the reinforcing bars and striking the concrete.In order to prevent left and right formwork from forming due to the pressure of concrete before striking the concrete, drill a hole in the left and the formwork with a steel wire, etc. The left and right molds are tightly tied. In this case, the reinforcing bars arranged between the left and right molds are not visible from the outside, so when the drill hole is drilled in the appropriate place of the formwork, the drill blade contacts the reinforcing bars and is easily damaged. It was replaced with a new one.

이에 따라 종래에는 작업장에 갈때에 여러개의 드릴을 준비하여 가져가야 하게 되고 작업이 끝난 귀가시에는 날이 손상된 여러개의 드릴을 가져와 연마하여 사용하여야 하게 되므로 고가의 드릴을 여러개 갖추는데 경제적으로 부담이 될 뿐만 아니라, 휴대, 보관에 있어서 많은 불편이 따르게 되었다.Therefore, conventionally, when going to the workplace, it is necessary to prepare and take several drills, and when returning to the end of work, it is necessary to bring and use several drills with damaged blades. In addition, there is a lot of inconvenience in carrying and storage.

본 고안은 상기와 같은 결점을 해소시킬 수 있도록 하기 위하여 전기드릴의 척부분에다 연마판을 부설하여 사용중 드릴의 날이 손상되었을 경우에는 간단히 연마하여 사용할 수 있도록 한 연마판을 부설한 전기드릴을 안출하게 된 것인데, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.In order to solve the above-mentioned drawbacks, the present invention lays an abrasive plate on the chuck part of the electric drill, and when the drill blade is damaged during use, an electric drill with an abrasive plate that can be simply polished and used is devised. If this is described in detail by the accompanying drawings as follows.

회전축(2)의 선단에 드릴(4)을 고정시킬 수 있도록 한 척(3)이 있는 공지의 전기드릴(1)에 있어서, 척(3)을 고정시키는 케이스부(3A)에 연마판(5)을 고무링(6)으로 압접되게 고정시켜서 된 것이다.In the well-known electric drill 1 with the chuck | zipper 3 which can fix the drill 4 to the front-end | tip of the rotating shaft 2, the grinding plate 5 is attached to the case part 3A which fixes the chuck | zipper 3. ) Is to be fixed by a rubber ring (6).

이와 같이 된 본 고안은 전기드릴(1)의 회전축(2)의 케이스부(3A)에 고무링(6)으로 서로 압접되게 연마판(5)을 고정시켜서 된 것이므로 작업중 드릴(4)의 날이 마모 및 손상되었을 때에는 드릴(4)을 전기드릴(1)의 척(3)에서 간단히 분리시키고 축(2)을 회전시켜 드릴(4)의 날을 제2도와 같이 연마판(5)에 접촉하여 연마시키면 되는데, 이 때 연마판(5)과 고무링(6) 및 케이스부(3A)의 표면은 서로 견고히 압접된 상태이므로, 슬립되어 연마효율이 불량하게 될 염려가 없다.Since the present invention is made by fixing the abrasive plates 5 to be pressed against each other by the rubber ring 6 to the case portion 3A of the rotating shaft 2 of the electric drill 1, the blade of the drill 4 during operation is When worn and damaged, the drill 4 is simply detached from the chuck 3 of the electric drill 1 and the shaft 2 is rotated to contact the blade of the drill 4 with the abrasive plate 5 as shown in FIG. The surface of the polishing plate 5, the rubber ring 6, and the case part 3A are firmly press-bonded with each other, so that there is no fear of slipping and poor polishing efficiency.

이와 같은 본 고안은 전기드릴(1)에 연마판(5)이 직접 설치되었으므로 드릴(4)이 사용중 손상되었을 경우에는 작업장에서 간단히 연마하여 사용하면 되므로, 종래 드릴(4)을 여러개 갖추어야 되는 경제적인 부담과 휴대 및 보관상의 불편을 덜 수 있는 효과가 있다.Since the present invention has an abrasive plate 5 directly installed on the electric drill 1, when the drill 4 is damaged during use, it can be simply polished and used in the workshop, and thus it is economical to have several conventional drills 4. It is effective to reduce the burden and inconvenience in carrying and storage.
