Description

철판 천공기의 원통형 양날 드릴Cylindrical Double-edged Drill in Steel Plate Drilling Machine

제1도는 본 고안의 사시도.1 is a perspective view of the present invention.

제2도와 제3도는 본 고안의 사용상태 단면도.2 and 3 is a cross-sectional view of the state of use of the present invention.

* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 중심축 1' : 나조부1: central axis 1 ': Najobu

2 : 톱날체 2', 2" : 톱날2: saw blade 2 ', 2 ": saw blade

3 : 천공기 4 : 소켓3: perforator 4: socket

5 : 고정캡5: fixed cap

본 고안은 중심축의 중앙에 형성된 나조부에 원통형 톱날체를 나사결합하여서 천공기의 소켓에 고정시켜 사용케 된 드릴에 있어서 톱날체의 양측으로 크기가 다른 톱날을 대향되게 형성하여 필요에 따라 위치를 변경시켜 해당크기의 구멍을 뚫을 수 있게 된 원통형 양날 드릴에 관한 것이다.The present invention is a drill that is used by screwing a cylindrical saw blade to a screw thread formed in the center of the central axis to be fixed to the socket of the punching machine to form a saw blade of different sizes on both sides of the saw blade body to change the position as necessary It relates to a cylindrical double-edged drill to be able to drill holes of the corresponding size.

종래의 톱날체는 일측에만 톱날이 형성되어서 같은 크기의 구멍만을 천공할 수 있게 되어서, 크기가 다른 구멍을 뚫을 경우 그에 따른 드릴을 별도로 구비해야 함으로 보관 및 사용이 불편할 뿐 아니라 다수의 부품을 지참하여야 하기 때문에 분실의 염려가 많은 결점이 있었다.Conventional saw blades are formed only on one side, so that only the same size of holes can be drilled, and when drilling holes of different sizes, a separate drill must be provided accordingly, which is not only inconvenient to store and use, but also to bring a large number of parts. Because of the fear of loss there were many defects.

본 고안에서는 이러한 결점을 해결하기 위해서 안출된 것으로 주로 열쇠뭉치 삽입구멍을 문에 천공하는데 사용되는 것으로 드릴의 톱날체에 직경이 다른 톱날을 대량 형성하여서 필요에 따라 톱날체를 뒤집어 고정시키고 사용하게 됨으로 뭉치의 크기에 따라 적당한 구멍을 뚫을 수 있게 된 것으로 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.In order to solve these drawbacks, the present invention is mainly used to drill the keyhole insertion hole into the door. The saw blades of different diameters are formed on the saw blades of the drill, so that the blade blades are fixed and used as needed. According to the accompanying drawings as to be able to drill a suitable hole according to the size of the bundle as follows.

중심축(1)의 나조부(1')에 원통형 톱날(2')이 형성된 톱날체(2)를 나사 결합하여서 천공기(3)의 소켓(4)에 고정캡(5)으로 고정시켜 사용케된 것에 있어서 톱날체(2)의 일측에 형성된 톱날(2') 대향측에 톱날(2')과 직경이 다른 톱날(2")을 형성하여서 됨을 특징으로 한 구성이다.Screw the saw blade body 2 with the cylindrical saw blade 2 'formed on the threaded portion 1' of the central shaft 1 to be fixed to the socket 4 of the perforator 3 with a fixing cap 5 for use. The saw blade 2 'is formed on the opposite side of the saw blade 2' formed on one side of the saw blade body 2, so that a saw blade 2 "having a different diameter from the saw blade 2 'is formed.

이와 같이 된 본 고안의 사용효과를 보면 철로된 문에 열쇠 뭉치 삽입구멍을 뚫고자 할 경우에 필요로 하는 구멍크기, 예를 들어 큰 구멍이 필요하면 제2도와 같이 톱날(2')이 전방으로 위치되도록 중심축(1)의 나조부(1')에 나사 결합시켜서 사용하며 적은 구멍의 경우에는 톱날체(2)만을 간단히 분리하여 제3도와 같이 뒤집어 고정시키고 사용할 수가 있어서 매우 편리하게 작업을 할 수 있고 드릴부품의 갯수를 줄일 수 있어 경제적인 고안인 것이다.According to the use effect of the present invention as described above, if the hole size required for drilling a key bundle insertion hole in a steel door, for example, if a large hole is required, the saw blade 2 'is moved forward as shown in FIG. It is used by screwing to the screw part 1 'of the central shaft 1 so that it can be positioned. In the case of a small hole, only the saw blade body 2 can be simply removed, and then turned upside down as shown in FIG. It is economical design because it can reduce the number of drill parts.
