본 고안은 T자형으로된 너트의 중공부에 나사구멍을 절삭 가공하는 태핑머신(tapping machine)에 관한 것이다.The present invention relates to a tapping machine for cutting a threaded hole in a hollow portion of a T-shaped nut.
종래에는 너트의 중공부에 나사구멍을 절삭 가공할 때 각각의 너트마다 일일이 탭(Tap)으로서 구멍을 절삭하기 때문에 작업이 불편하면서도 비능율적이고 바이트를 선반이나 기타 공작기계에 물려서 너트에 나사 구멍을 형성하는 것 역시 너트를 일일이 기구에 물려서 조작해야 되기 때문에 많은 시간과 인력이 소요되는 등의 문제점이 있었고, 특히 소형너트에 나사구멍을 가공하기에는 공정상의 어려움이 있었다.Conventionally, when cutting a screw hole in the hollow part of the nut, since each hole is cut by a tap as a tap, the work is inconvenient and inefficient. Forming also has a problem such as a lot of time and manpower is required because the nut is to be bit by hand to operate the instrument, in particular, there was a difficulty in processing the screw hole in the small nut.
본 고안은 이와같은 결점을 제거하고저 한 것으로서 이를 첨부도면에 의해 상세히 설명하면 다음과 같다.The present invention is to remove these drawbacks as described in detail by the accompanying drawings as follows.
기계본체(1)의 일측상부에 가공용 너트의 주입통(2)을 형성하여 가공용너트가 안내레일(3)을 따라 낙하되면서 가공되게한 것에 있어서 기계본체(1)의 상판(4)으로 지지벽(5)(6)을 입설하여 지지벽(5)(6) 사이로 안내봉(7)(8)을 수평으로 삽지 고정하되 일측 지지벽(5)에는 시린더(51)와 피스톤로드(52)를 설치하여 피스톤로드(52)의 선단에는 안내봉(7)(8)에 끼워지고 상단 양측으로 집게(53)가 형성된 왕복대(54)를 부착하고 왕복대(54)의 선단부에는 T자형의 요홈(55)을 형성한다.The support wall is formed by the upper plate 4 of the machine body 1 in forming the injection nut 2 of the processing nut on the upper side of the machine body 1 so that the processing nut falls down along the guide rails 3 and is processed. (5) (6) is inserted and the guide rods (7) (8) are inserted and fixed horizontally between the support walls (5) and (6), but the cylinder (51) and the piston rod (52) are supported on one support wall (5). And a carriage 54 fitted with guide rods 7 and 8 at the front end of the piston rod 52 and having tongs 53 formed at both sides of the upper end thereof, and having a T-shape at the tip of the carriage 54. The recess 55 is formed.
한편 타측 지지벽(6)에는 양측으로 걸림돌조(61)와 중앙으로 절결된 통체(62)를 수평으로 돌설하고 절결된 통체(62)의 중심부로 회전탭(63)을 축설하여 왕복대(54) 선단의 T자형 요홈(55)에 물려진 가공용너트(9)가 회전탭(63)에 진입되면 나사구멍이 절삭 가공되게 한 것으로서 도면중 미설명부호(56)은 왕복대(54) 상단으로 집게(53)의 누름판, (58)은 스프링으로 탄발되는 탄지봉이고, (10)은 나사구멍이 절삭 가공된 너트이며, (64)는 회전탭(63)의 축이다.Meanwhile, the other supporting wall 6 horizontally protrudes the locking projection 61 and the cylinder 62 cut in the center on both sides, and the rotary tab 63 is formed in the center of the cut cylinder 62 to reciprocate the carriage 54. ) When the processing nut 9 bited by the T-shaped groove 55 at the tip enters the rotary tab 63, the threaded hole is cut and the description 56 in the drawing is directed to the upper end of the carriage 54. The holding plate 58 of the tongs 53 is a carbon rod which is springed with springs, 10 is a nut whose threaded hole is cut, and 64 is an axis of the rotary tab 63.
이와같이 형성된 본 고안은 가공용 너트(9)는 주입통(2)으로부터 안내레일(3)을 거쳐 왕복대(54) 선단의 T자형 요홈(55)에 제2a도의 상태와 같이 삽지 괘지된다.According to the present invention formed as described above, the processing nut 9 is inserted and inserted into the T-shaped groove 55 at the tip of the carriage 54 from the injection cylinder 2 through the guide rail 3 as shown in FIG.
이때 일측 지지벽(5)에 설치된 피스톤로드(52)는 최대한도 시린더(51)쪽으로 당겨져서 양측 집게(53)의 누름판(57)은 탄지봉(53)의 누름판(57)은 탄지봉(58)에 압지된 상태가 된다.At this time, the piston rod 52 installed on one side of the support wall 5 is pulled toward the cylinder 51 as much as possible, so that the pressing plates 57 of both clamps 53 are the pressing plates 57 of the carbon rods 53 and the carbon rods. 58) is pressed.
그후 시린더(51)가 작동하여 피스톤로드(52)가 점진적으로 전진될 때 왕복대(54)의 양측에는 항시 수평으로 된 안내봉(7)(8)이 삽입되어 있어 피스톤로드(52)가 전진함에 따라서 선단에 부착된 왕복대가 제2b도의 상태에서와 같이 전진되다가 절결된 통체(62) 내부로 점차 진입하게 되면 가공용너트(9)의 중공부로 회전탭(63)이 삽입 회전되기 때문에 나사구멍이 완성되었을 때 집게(53)의 누름판(57) 외측에는 지지벽(6)에 수평으로 입설된 걸림돌조(61)가 부딪치게 되어 그후 왕복대(54)가 더욱 전진하면 제2c도 상태와 같이 집게(53)는 걸림돌조(61)에 제어되어 양측으로 벌어져서 왕복대(54) 선단의 T자형 요홈(55)은 개방되기 때문에 회전탭(63)에서 절삭 가공된 너트(10)는 왕복대(54)가 전진함에 따라 회전탭 축(64) 안쪽으로 삽입되어 외부로 배출되는 것이고, 피스톤로드(52)가 다시 후진하게 되면 제2d도 상태와 같이 집게(53)가 벌어진 상태로 왕복대(54)가 후진되다가 집게(53) 누름판(57)의 내측으로 지지벽(5)에 수평으로 돌설된 탄지봉(58)이 부딪치게 되면 집게(53)는 다시 원위치로 복원되어 제2e도 상태와 같이 되는 것이고, 왕복대(54) 선단의 T자형 요홈(55)으로 가공용너트(9)가 제2a도 상태와 같이 다시 낙하 주입되면 전기 반복작용으로서 왕복대(54)가 전진되어 회전탭(63)에 의해 가공용너트(9)에 나사구멍을 절삭 가공하는 것으로서 이와같은 기계동작은 공지의 전자회로로서 정확히 조작하여 주는 것이다.Thereafter, when the cylinder 51 is operated and the piston rod 52 is gradually advanced, guide rods 7 and 8 which are always horizontal are inserted into both sides of the carriage 54 so that the piston rod 52 is inserted. As the carriage attached to the tip is advanced as in the state of FIG. 2B and gradually enters into the cut cylinder 62 as it moves forward, the rotary tab 63 is inserted into the hollow of the processing nut 9 so that the screw hole is rotated. When this is completed, the engaging projection 61 horizontally placed on the support wall 6 hits the outer side of the pressing plate 57 of the tongs 53. Then, when the carriage 54 is further advanced, the tongs as shown in FIG. Since the 53 is controlled by the locking protrusion 61 and opens to both sides, the T-shaped groove 55 at the tip of the carriage 54 is opened, so that the nut 10 cut at the rotary tab 63 is moved to the carriage 54. ) Is inserted into the rotary tap shaft 64 and discharged to the outside as the piston moves forward. When the 52 is reversed again, the carriage 54 is retracted with the tongs 53 open as shown in FIG. 2D, and then horizontally protrudes to the support wall 5 toward the inside of the tongs 57 of the tongs 53. When the tungsten rod 58 strikes, the tongs 53 are restored to their original positions, and the second toe state is the same as the state of the second e, and the processing nut 9 is formed by the T-shaped groove 55 at the tip of the carriage 54. As shown in the drawing, when the drop is injected again, the carriage 54 is advanced as an electric repetitive action, and the thread hole is cut into the processing nut 9 by the rotary tab 63. Such mechanical operation is a known electronic circuit. It is to operate correctly.
따라서 본 고안은 종래와 같이 개별적으로 너트에 나사구멍을 절삭 가공하는 것이 아니고 왕복대(54)의 전후 이동 작용으로서 가공용너트(9)를 연속적으로 집게(53)에 물려 이동시켜서 회전탭(63)에 의해 절삭 가공함과 동시에 회전탭축(64)으로 절삭 가공된 너트(10)를 실에 구슬을 끼우는 것과 같이 밀어넣어 가공 배출하므로서 작업시간의 단축은 물론 불량품의 생산을 최대한 방지할 수 있고 작업능율을 높일 수 있는 것이다.Therefore, the present invention does not individually cut the screw holes in the nut as in the related art, but instead moves the processing nut 9 into the tongs 53 continuously as the forward and backward movement of the carriage 54 to rotate the rotary tab 63. By cutting and processing the nut 10, which has been cut by the rotary tap shaft 64, by inserting a thread into the thread as well as cutting the working time, and preventing the production of defective products as much as possible. To increase.
