가공 버어 제거장치{A BERR REMOVING DEVICE}Processing Burr Removal Device {A BERR REMOVING DEVICE}

본 발명은 가공 버어 제거장치에 관한 것으로서, 보다 상세하게는 고압의 유체를 이용하여 소재의 모서리부분이나, 오일홀의 내부에 남아있는 미세한 가공 버어의 제거와 세정작업을 동시에 수행 할 수 있도록 하는 가공 버어 제거장치에 관한 것이다.The present invention relates to a processing burr removing apparatus, and more specifically, processing burrs that can simultaneously perform the removal and cleaning of the fine processing burrs remaining in the corners of the material or in the oil holes using high pressure fluid. It relates to a removal device.

일반적으로 자동차 메이커에서 한 대의 완성차를 생산하기 위해서는 소재의 선택에서부터 제품양산까지 수많은 공정을 거쳐 이루어지며, 특히, 실린더 헤드와 실린더 블록으로 이루어지는 엔진 및 캠 샤프트, 크랭크 샤프트 등은 주조공정을 통하여 그 몸체를 제작한 후, 수차례의 가공공정을 거쳐 완성품으로 만들어지고 있다.In general, in order to produce a finished car in an automobile maker, a number of processes are performed from the selection of materials to the mass production of products. In particular, the engine, cam shaft, and crankshaft, etc., which consist of a cylinder head and a cylinder block, are formed through a casting process. After fabrication, the process is carried out several times to make the finished product.

이와 같이, 주조를 통하여 제작되는 실린더 블록, 실린더 헤드, 캠 샤프트 및 크랭크 샤프트 등은 상형과 하형으로 나누어지는 주형을 이용하게 되며, 이러한 주형에 고온의 용탕을 부어 주물을 만든 후, 상기 상형과 하형을 탈거하여 소재를 제작하게 된다.As such, the cylinder block, cylinder head, camshaft, and crankshaft manufactured through casting use a mold divided into an upper mold and a lower mold, and after pouring molten metal at a high temperature into the mold, the upper mold and the lower mold Remove the material to make the material.

이와 같이 주조공정을 통하여 제작되는 소재는 컨베이어 등의 이송수단을 통하여 호닝(honing)공정 등을 포함하는 다수의 가공공정을 거치게 되는데, 이 때, 상기 소재는 각 모서리부분과 오일홀 등에 가공 버어가 남게 되며, 이를 제거하기 위하여 상기 가공공정의 마지막 단계에서 작업자가 직접 에어 툴이나 페이퍼 또는 전수 숫돌 등을 이용하여 상기 소재의 각부 가공 버어를 제거하고 있다.As such, the material produced through the casting process is subjected to a plurality of processing processes including a honing process and the like through a conveying means such as a conveyor. At this time, the material is processed at each corner and oil hole. In order to remove this, in the last step of the machining process, the operator directly removes the processing burrs of each part of the material by using an air tool, a paper, or a whetstone.

그러나 상기한 바와 같이, 에어 툴이나, 페이퍼 또는 전수 숫돌을 이용하여 소재의 가공 버어를 제거하는 종래의 방법으로는 소재의 오일홀이나, 손이 미치지 않는 모서리부분의 가공 버어를 제거하는 것은 불가능하며, 제거 후에도 이를 소재로부터 완전히 분리하기는 어려워 소재의 균일한 품질 확보가 어렵다는 문제점을 내포하고 있다.However, as described above, it is impossible to remove the oil hole of the material or the processing burr of the untouched edge by the conventional method of removing the processing burr of the material by using an air tool, paper, or grinding wheel. Even after removal, it is difficult to completely separate it from the material, which implies that it is difficult to ensure uniform quality of the material.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 창출된 것으로서, 본 발명의 목적은 가공공정을 거치면서 발생되는 소재의 각 모서리부나 오일홀 등의 좁은 공간부에 발생되는 버어(burr)를 고압의 유체를 이용하여 버어 제거는 물론 세정작업까지 동시에 이룰 수 있도록 하는 가공 버어 제거장치를 제공하는 것이다.Therefore, the present invention was created to solve the above problems, an object of the present invention is to provide a high pressure burr (burr) generated in the narrow space portion, such as each corner of the material or oil hole generated during the processing process It is to provide a processing burr removal apparatus that can achieve the removal of the burr as well as the cleaning operation using the fluid of the same time.

In the state where the cylinder block 1 is seated and fixed on the fixing jig 3, the robot 5 behaves and its arm 7 The injection nozzle 9 mounted at the tip end is inserted into the oil hole 8 of the cylinder block 1.

이러한 상태에서, 상기 분사노즐(9)의 각 분사구(25,27,29,31)가 상기 오일홀(8) 내에 분기되는 오일홀(10)의 위치까지 삽입되면, 상기 분기되는 오일홀(10)의 분기각(β1,β2)을 스펙(사양지)으로부터 확인하여 상기분사각(α1,α2,α3,α4)이 일치하거나 비슷한 정도의 분사구(25,27,29,31)가 상기 분기되는 오일홀(10)에 위치되도록 상기 분사노즐(9)을 회전시킨 후, 상기 고압펌프(11)로부터의 고압유체를 공급하여 분사시키게 된다.In this state, when each injection port 25, 27, 29, 31 of the injection nozzle 9 is inserted to the position of the oil hole 10 branched in the oil hole 8, the branched oil hole 10 The branch angles β1, β2 of the After rotating the injection nozzle 9 so as to be located in the oil hole 10, the high pressure fluid from the high pressure pump 11 is supplied and sprayed.

그러면, 상기 분기되는 오일홀(10) 내부 또는 그 모서리부분에 생성된 버어(40)는 상기 고압유체에 의해 제거(디버링)되며, 동시에 상기와 같은 오일홀(8) 및 분기되는 오일홀(10)의 경우에는 그 내부를 상기 고압유체를 통하여 세척하는 등의 효과가 있는 것이다.Then, the burr 40 generated inside or in the corner portion of the branched oil hole 10 is removed (deburred) by the high pressure fluid, and at the same time, the oil hole 8 and the branched oil hole 10 as described above. ), There is an effect such as washing the inside through the high pressure fluid.

상술한 바와 같이 본 발명에 따른 가공 버어 제거장치에 의하면, 가공공정을 거치면서 발생되는 소재의 각 모서리부나 오일홀 등의 좁은 공간부에 발생되는 버어(burr)를 고압의 유체를 이용하여 버어 제거는 물론, 세정작업까지 동시에 이룰 수 있어, 균일한 제품품질을 확보할 수 있는 효과가 있다.As described above, according to the processing burr removing apparatus according to the present invention, the burr generated in each of the corners of the raw material or the narrow space such as the oil hole generated during the processing process is removed by using a high pressure fluid. Of course, since the cleaning can be achieved at the same time, there is an effect that can ensure a uniform product quality.
