본 발명은 드릴 가공시의 발생하는 칩을 제거하는 칩 제거용 장치에 관한 것으로, 좀 더 상세하게는 드릴 작업시 외부로 배출되는 칩을 효과적으로 제거하는 장치에 관한 것이다.The present invention relates to a chip removing apparatus for removing chips generated during drilling, and more particularly, to an apparatus for effectively removing chips discharged to the outside during drilling.

일반적으로 전기 드릴링 머신은 드릴을 회전시키면서 회전축 방향의 이송으로 가공물에 구멍을 뚫는 드릴 작업이 기본 작업이 되고, 또한 뚫린 구멍을 완성 가공하거나 또는 넓히면서 가공하는 보오링 등을 비롯하여 기계 공작 과정에서 각종 작업이 이용된다. 드릴 작업은 가공할 지름, 구멍을 뚫을 위치 및 요구되는 정밀도 등에 따라 사용할 공구 및 전기 드릴링 머신의 종류들이 달라져서 그 형식이 매우 많다.In general, the electric drilling machine is a basic operation of drilling a hole in the workpiece in the direction of the axis of rotation while rotating the drill, and also a variety of operations in the machining process, including boring to complete or widen the drilled hole This is used. Drilling works vary widely depending on the type of tool and electric drilling machine to be used, depending on the diameter to be machined, the location of the hole to be drilled and the required precision.

특히 드릴 작업시에는 드릴 가공을 하게되는데, 이때 칩의 최소화가 이루어짐과 동시 제품의 외부에 칩이 배출되어 진다. 이 칩은 작업환경을 불결하게 만들고, 칩이 비산됨으로써 작업자의 안전을 해칠 수 있으며, 제품의 표면에 스크레치를 발생시킬 소지가 다분하다.In particular, when drilling, the drill is processed, and the chip is minimized and the chip is discharged to the outside of the product at the same time. This chip makes the working environment dirty, the scattering of the chip can harm the safety of workers, and there is a possibility of scratching the surface of the product.

따라서 이를 제거하는 것이 필요하였는데 종래에는 칩이 발생하면 그 칩을 제거하기 위해서 콤퓨레셔로부터 공급되는 압축공기를 불어서 외부로 칩을 비산시켜 제거하거나, 진공청소기를 이용하여 칩을 흡입함으로써 제거를 하게 되는데, 이때 전자의 경우 압축공기를 공급하기 위한 콤퓨레셔와 호스 등을 필요로 하게되며, 후자의 경우 진공청소기와 이를 구동하기 위한 전원장치 등을 필요로 하게 된다.Therefore, it was necessary to remove them. In the past, when chips are generated, the chips are blown out by blowing compressed air supplied from the compressor to remove the chips, or removed by suctioning the chips using a vacuum cleaner. In this case, the former requires a compressor and a hose for supplying compressed air, and the latter requires a vacuum cleaner and a power supply for driving the same.

한편, 특10-2000-0066696 '집진 장치가 구비된 에어 핸드드릴'에서 공기로 작동되 는 드릴링 머신에서 배기 에어를 이용하여 칩을 집진하는 구조로서 사용됨으로써, 본 발명인 칩 집진장치가 흡입공에 설치되는 것과는 상반되며, 그 작동법 또한 외부의 콤퓨레셔에 의해서 발생한 공압으로 작동하는 에어 핸드드릴에 있어서 사용후 배기되는 배기 에어를 이용한다는 점에서 차이가 있다.On the other hand, it is used as a structure for collecting chips using exhaust air in a drilling machine operated by air in the air 10-2000-0066696 'air hand drill with a dust collector', the chip dust collector of the present invention to the suction hole In contrast to the installation, the operation method also differs in that the air hand drill operated by pneumatic pressure generated by an external compressor uses exhaust air that is exhausted after use.

또한 실20-1992-0009089 '전기드릴의 칩 제거장치'에서는 모터의 회전축에 팬(6)을 고정하여 팬(6)의 회전에 따라 모터를 냉각시키도록 된 것에 있어서, 팬의 회전시 발생하는 배기 에어를 이용하여 팬의 배기공에 제거장치를 장착하여 칩을 불어서 외부로 칩을 비산시키는 작동을 함으로써 본 발명의 흡입공에 칩 집진장치를 장착하여 칩을 집진한다는 것과 상이하다.In addition, the seal 20-1992-0009089 'chip removal device of the electric drill' is to fix the fan 6 to the rotating shaft of the motor to cool the motor according to the rotation of the fan 6, It is different from installing a chip collector in the suction hole of the present invention by collecting a chip in the suction hole of the present invention by attaching the removal device to the exhaust hole of the fan using the exhaust air to blow the chip to the outside.

또한 드릴 작업을 통한 생산공정에 있어서, 제품의 가공시 발생하는 칩을 제거하기위해 별도의 제거공정을 필요로 하게되어 작업시간이 오래 걸리게 되고, 작업효율이 저하되며, 생산성이 떨어짐은 물론이고, 외부로 노출된 칩에 의해 작업환경이 불결해 지는 문제점을 야기하였다.In addition, in the production process through the drill operation, a separate removal process is required to remove chips generated during processing of the product, which takes a long time, reduces work efficiency, and decreases productivity. It caused a problem that the working environment becomes dirty by the chip exposed to the outside.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로서, 제품의 드릴 가공시 발생하는 칩을 제거하기 위하여 별도의 압축공기와 진공청소기를 이용하지 않고, 또한 별도의 제거공정에 투입함이 없이, 빠르게 제거하여 작업시간을 단축하고, 작업효율을 높이며, 생산성을 향상시키고, 외부로 노출된 칩을 없게 함으로써 작업환경을 청결하게 하는 것을 목적으로 한다.Therefore, the present invention has been made to solve the above problems, without using a separate compressed air and vacuum cleaner to remove the chips generated during the drilling process of the product, and also without input into a separate removal process It aims to clean the working environment by removing the chips quickly, shortening working time, increasing working efficiency, improving productivity, and eliminating external chips.
