본 고안은 다단환봉 드릴작업시의 가공 보조장치 즉, 드릴가공지그(Jig)에 관한 것으로, 특히, 기계부품등의 가공물을 드릴가공시에 단순개폐동작에 의해 가공물 고정 및 작업완료후 취출에 이르기까지 용이하게 수행할 수 있는 다단환봉 드릴작업시의 가공 보조장치인 것이다.The present invention relates to a processing aid for multi-stage round bar drilling, i.e., a drill processing jig. In particular, the workpiece is fixed and taken out after completion of work by simple opening / closing operation when drilling a workpiece such as a machine part. It is a processing aid for multi-stage round bar drill operation that can be easily performed.

종래의 경우 도면 제3도에서 보는 바와같이 드릴가공지그는 본체(10)에 가공물(40)을 삽입하고, 세트스크류(30)로 고정한다음, 드릴홈(20)에 삽입되는 원통형부시(50)의 안내를 받아 드릴홈을 가공하여 가공작업 완료 후에는 전술한 순서의 역순으로 세트스크류(30)를 풀고, 가공한 가공물(40)을 취출하는 구조이었다.In the conventional case, as shown in FIG. 3, the drill processing jig inserts the workpiece 40 into the main body 10, fixes the set screw 30, and then inserts the workpiece 40 into the drill groove 20. After processing the drill groove by receiving the guide, the set screw 30 was unwound in the reverse order of the above-described procedure, and the processed workpiece 40 was taken out.

그러나, 가공물(40)을 가공하기 위하여 고정하는 세트스크류(30)를 죄었다 풀었다 하는데 따른 작업시간이 많이 소요되었고, 또한, 원통형부시(50)를 사용하므로 드릴작업시에 원통형 부시(50)가 드릴방향과 같은 수직방향으로 밀리게 되어, 가공물(40) 취출에 어려움 및, 표면에 흠집이 생기게 되는 문제점이 발생하였다.However, it takes a lot of work time due to tightening and loosening the set screw 30 fixed to process the workpiece 40, and also uses a cylindrical bush 50, the cylindrical bush 50 at the time of drilling Is pushed in the vertical direction such as the drill direction, so that the workpiece 40 is difficult to take out and a problem occurs that the surface is scratched.

따라서, 본 고안은 상술한 바와같은 종래의 제반 문제점을 감안하여 안출된것으로 본 고안의 목적을 달성하기위한 기술적 구성 및 작용효과를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Therefore, the present invention has been devised in view of the above-mentioned conventional problems as described above in detail with reference to the accompanying drawings, the technical configuration and effect for achieving the object of the present invention.

다단환봉 드릴작업시의 가공 보조장치에 있어서, 가공물 고정기능의 플런저(3)가 삽입 고정되고, 양측부에 고정홈을 형성하는 개폐부(2)와, 가공물(4)을 가공키위한 드릴홈(1c)을 적어도 4곳이상 천공하고, 개폐부(2)를 고정하는 고정홈(1a)과 공기홀(1b)을 갖는 본체(1)를 구비하여, 회전축(6)을 매개로 본체(1)와 개폐부(2)를 개폐가능토록 결합시키는 한편, 본체(1)와 개폐부(2)의 고정홈(1a)(2a)에 결합 또는 분리하여, 개폐동작을 간섭하는 고정핀(7)으로 구성된 것으로, 미설명부호 8은 손잡이인 것이다.In the processing assistance device in the multi-stage round bar drill operation, the plunger 3 having the workpiece fixing function is inserted and fixed, and the opening and closing portion 2 which forms the fixing groove at both sides thereof, and the drill groove for processing the workpiece 4 ( Perforating at least four places 1c), and having a main body 1 having a fixing groove (1a) and an air hole (1b) for fixing the opening and closing portion 2, and the main body (1) and the rotation shaft (6) It is composed of a fixing pin (7) for interlocking the opening and closing portion (2) to open and close, coupled or separated from the main body (1) and the fixing groove (1a) (2a) of the opening and closing portion 2, to interfere with the opening and closing operation, Reference numeral 8 is a handle.

이상과 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다. 가공물(4)의 드릴가공 작업시에 도면 제2도(a)(b)에서 보는 바와같이 본체(1)에 가공물(4)을 삽입하고, 개폐부(2)의 손잡이(8)를 시계방향과 같은 화살표 ″P″와 같은 방향으로 동작시키면 회전축(6)에 의해 개폐부(2)는 닫혀진 상태로되고, 본체(1)와 개폐부(2)의 고정홈(1a)(2a)에 고정핀(7)을 삽입하여 개방됨을 방지하면, 플런저(3)에 의해 가공물(4)의 위치를 고정시키게 된다.Referring to the effect of the present invention configured as described above are as follows. During the drilling operation of the workpiece 4, the workpiece 4 is inserted into the main body 1, as shown in FIG. 2 (a) and (b), and the handle 8 of the opening and closing portion 2 is turned clockwise. When operating in the same direction as the arrow ″ P ″, the opening and closing portion 2 is closed by the rotation shaft 6, and the fixing pin 7 is fixed to the fixing grooves 1a and 2a of the main body 1 and the opening and closing portion 2. By preventing the opening by inserting), the position of the workpiece 4 is fixed by the plunger 3.

이때, T형부시(5)의 안내를 받아 가공물(4)의 드릴작업을 하게되고, 드릴작업 완료후에 고정핀(7)을 고정홈(1a)(2a)에서 분리하고, 개폐부(2)를 개방하여 본체(1)에서 가공물(4)을 취출하게 되는 것이다. 또한, T형부시(5)의 그 구조상, 드릴작업시에 드릴 작업방항과 같은 수직으로 밀리지 않게되어 가공물의 취출이 용이하고, 개폐부(2)의 닫힘에 따라 본체(1)내의 공기압축이나 진공을 공기홀(1b)에 의해 방지하게 된것이다.At this time, the work of the workpiece 4 is drilled under the guidance of the T-shaped bush 5, and after completion of the drilling work, the fixing pin 7 is separated from the fixing grooves 1a and 2a, and the opening and closing part 2 is removed. The workpiece 4 is taken out from the main body 1 by opening. In addition, due to the structure of the T-shaped bush 5, it is prevented from being pushed vertically as in the drill working direction during the drilling operation, and the take-out of the workpiece is easy, and the air compression or vacuum in the main body 1 is closed as the opening / closing part 2 is closed. This is prevented by the air hole (1b).

이상에서 본 바와같이 본 고안은 다단환봉의 드릴가공시에 직각정밀도를 향상시키고, 가공물을 다수곳 천공한 드릴홈(1c)에 의해 동시에 여러개 작업할 수 있어, 드릴가공 생산성의 효과를 향상시키게된 고안인 것이다.As can be seen from the above, the present invention improves the right-angle precision during the drilling of multi-stage round rods, and can simultaneously work a plurality of drill grooves (1c) for drilling a plurality of workpieces, thereby improving the effect of drilling productivity. It is an idea.
