본 발명은 구멍 입구 면취 가공장치에 관한 것으로서, 특히 고유한 형태의 면취공구를 기계부품 가공설비에 장착하여 기계부품에 형성된 구멍 입구의 모서리를 제거하는 면취 가공장치에 관한 것이다.The present invention relates to a hole inlet chamfering device, and more particularly to a chamfering device for removing the corners of the hole inlet formed in the machine part by mounting a unique type of chamfering tool to the machine parts processing equipment.

나사구멍등 구멍이 형성되어 있는 기계부품에 있어서는 구멍 입구의 모서리가 날카로워 이를 떼어 내야 하는데 종전에는 줄(File)이나 칼날 같은 끌을 이용하여 구멍 입구의 모서리 제거 즉 면취 가공을 수작업으로 하여 왔는바, 거칠게 가공되어 면취 형상이 불규칙한 상태로 되거나, 취급 부주의로 외관 찍힘을 유발하여 외관이 불량하게되는 폐단이 있었다. 또한 작업의 질을 높이기 위해서는 작업자의 많은 숙련이 요구되었다.Machine parts with holes, such as screw holes, have sharp edges at the openings, so they must be removed. In the past, the edges of the hole openings were removed by hand using a file or a knife. There was a closed end that was roughly processed, resulting in an irregular shape of the chamfer, or inadequate appearance caused by careless handling. Also, in order to improve the quality of the work, many skilled workers were required.

본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위하여 전용 면취 가공 공구를 기계부품 가공설비에 장착하여 기계부품에 형성된 구멍 입구의 모서리를 제거하는 면취 가공장치를 제공함에 있다.An object of the present invention is to provide a chamfering device for removing the edge of the hole inlet formed in the machine part by mounting a dedicated chamfering tool in the machine parts processing equipment in order to solve the conventional problems as described above.

본 발명의 다른 목적은 범용 공작 기계로는 불가능한 좁은 공간에서의 면취 가공을 가능하게하여, 공간 활용을 효율적으로 하며 구조가 간단하고 조작이 쉬운 면취 가공장치를 제공함에 있다.Another object of the present invention is to provide a chamfering processing in a narrow space that is impossible with a general-purpose machine tool, to efficiently utilize space, and to provide a chamfering processing device having a simple structure and easy operation.

이와 같은 목적을 달성하기 위하여 본 발명은 면취날이 형성된 면취공구를 마련하고 이를 공구안내축, 축 고정링, 슬라이딩하우징 등으로 이루어진 공구파지구에 결합하여서된 것을 특징으로 한다.In order to achieve the above object, the present invention is characterized by providing a chamfering tool is formed with a chamfering blade and coupled to a tool holding tool consisting of a tool guide shaft, a shaft fixing ring, a sliding housing.

First, as shown in detail in FIG. 3, the chamfering tool 1 according to the present invention forms a lower surface of the front end of the elongated rod-shaped main body 2 as the inclined surface 3, and the chamfered blade symmetrically opposite to the inner side of the inclined surface 4. ') (4 ") is provided with the protruding piece (4) formed at both ends, while the rear portion of the main body 2 is bent upwards and then bent forward again to form a bend in the direction of about 180 degrees with the main body (2) Then, the bearing engaging groove 6 is provided on the upper surface near the end of the bent portion 5. Chamfering blades 4 'and 4' 'are formed in the material and the processing speed as shown in FIG. The tool guide shaft 11 constituting the tool gripping tool 10 has a small diameter portion 22 in the front portion and a large diameter portion 13 in the middle portion thereof. (14), the tool diameter groove (17) is formed in the small diameter portion (12) and the large diameter portion (13) and the tip of the large diameter portion (13) A locking hook 15 is provided, and a tool storage cavity 16 is provided from the tip of the large diameter portion to the inside thereof, while a shaft fixing ring 20 is provided around the rear end of the large diameter of the tool guide shaft 13. And the sliding housing 21 provided with an inward flange 22 at the front end of the shaft fixing ring 20 with a sliding material on the outer surface of the shaft fixing ring 20. The sliding housing 21 and the tool guide are coupled to each other. A bearing 25 is interposed between the shaft large diameter portion 13 so that sliding does not occur with respect to the inner surface of the sliding housing 21. The chamfering tool 1 is coupled to the tool holding tool 10 configured as described above. The chamfering tool 1 of the tool fitting groove 17 provided in the small diameter portion 12 and the large diameter portion 13 of the tool guide shaft 11 and the tool storage cavity 16 provided in the large diameter portion 13. When the first stage is bent from the bent portion 5, it is coupled in the state shown in Figure 2. Reference numeral 27 is a drill chuck, and 28 is a worktable.

이어서 본 발명의 작용을 설명함에 있어서, 먼저 구멍의 한쪽면 면취 작업 과정을 제1도, 제2도 및 제5도를 참조하면서 살펴보기로 한다. 먼저 모타(29)를 작동시킨 후 외손으로 슬라이딩하우잉(21)을 잡고 전방으로(제2도에서는 오른쪽으로) 밀면 면취공구(1)가 베어링 걸림요홈(6)에 박힌 베어링 (25)에 끌려 전체적으로 미끄러지면서 전진하여 위치(A)에서 위치(B)로 이동되며 따라서 공구의 선단부분은 경사면(12)에 의하여 위로 솟아 오르고 면취날(4')(4")이 형성된 돌출편(4)도 도시한 바와 같이 공구안내축 소직경부(12) 선단부로부터 상향 돌출된다. 이와 동시에 오른손으로 잡고 있던 가공부품(30)을 부품 안내블록(35)의 안내홈(미도시)을 따라 밀어 부품구멍 (31)에 공구안내축 소직경부(12)의 선단이 삽입되도록 한다음 적은 힘으로 일정한 양만큼 다시 밀어주면 제5도에 도시된 바와 같이 구멍한쪽 모서리의 면취 가공이 이루어진다. 만일 제6도에 도시된 바와 같이 구멍(33)의 반대쪽 모서리에 면취 가공을 하려면 면취공구(10)를 돌출시키지 않은채 공구안내축의 소직경부(12)의 선단을 구멍에 삽입하여 완전히 구멍(33)을 관통시킨 다음 슬라이딩하우징(21)을 밀어 면취공구(1)의 돌출편(4)을 솟아오르게 하여 뒷날(4")로 면취 가공을 하면 된다. 구멍이 동심축상에 연속 위치되어 있을 경우에도 공구안내축을 앞쪽 구멍을 통과시킨 후 뒤쪽 구멍에 면취 가공할 수 있음이 제6도에 도시되어 있다.Next, in describing the operation of the present invention, a process of chamfering one side of a hole will be described with reference to FIGS. 1, 2, and 5. First, after operating the motor 29, grab the sliding housing (21) with an external hand and push it forward (to the right in FIG. 2), the chamfering tool (1) is attracted to the bearing (25) embedded in the bearing engaging groove (6) Sliding forward as a whole to move from position (A) to position (B), so that the tip of the tool is raised upward by the inclined surface 12 and the protruding piece 4 having chamfered edges 4 'and 4 "is also formed. As shown in the drawing, the tool guide shaft is projected upwardly from the tip of the small diameter portion 12. At the same time, the machined part 30 held by the right hand is pushed along the guide groove (not shown) of the part guide block 35. When the tip of the tool guide shaft small diameter portion 12 is inserted into the cylinder, the front end of the tool guide shaft 12 is pushed by a predetermined amount with a small force, and as shown in FIG. As shown in the opposite corner of the hole 33 To perform the chamfering process, insert the tip of the small diameter portion 12 of the tool guide shaft into the hole without protruding the chamfering tool 10, completely penetrate the hole 33, and then push the sliding housing 21 to chamfer the tool chamfering tool (1). What is necessary is to raise the protruding piece 4 of chamfer, and to chamfer with a back blade 4 ". It is shown in FIG. 6 that the tool guide shaft can be chamfered into the rear hole after passing through the front hole even when the hole is continuously positioned on the concentric axis.

이와 같이 본 발명에 의한 면취 가공장치는 간단한 구조의 면취공구(1)를 공구파지구(10)에 결합하여 이를 기존 부품 가공설비의 척에 장착 사용할 수 있어 그 제작이 쉬우며 제조원가도 높지않다. 또한 본 장치는 종래의 수작업에 비해서는 미숙련자가 가공하더라도 가공의 질이 비교할 수 없을 정도로 우수하며 가공 작업 또한 아주 용이하다. 뿐만 아니라 자동기계 이용에 의한 부품의 양산시 본체설비에 본 장치를 장착하여 부품 본체의 가공 시간을 활용하여 면취 가공할 수 있어 집중적으로 과다한 양을 처리하는 기계 조립자의 사상작업 공수를 덜어준다.As described above, the chamfering processing apparatus according to the present invention can be used by mounting the chamfering tool 1 having a simple structure to the tool holding tool 10 and mounting it on a chuck of an existing component processing equipment, and its manufacturing is easy and manufacturing cost is not high. In addition, the device is incomparably superior in quality compared to the conventional manual work, and the processing quality is also very easy. In addition, when the mass production of parts by automatic machine, this device can be installed in the main body equipment to be chamfered by using the processing time of the main body of the parts, thereby reducing the workman's finishing work of the machine assembler who handles the excessive amount intensively.

이와 같이 본 장치를 이용하면 생산성 및 품질이 뛰어나게 향상되어 현저한 원가절감을 기할 수 있다.By using this device as described above, the productivity and quality are greatly improved, resulting in remarkable cost reduction.
