특히, 외부의 전동공구 또는 수동공구와 체결되어 탭(4)이 흔들리지 않고 가공하려는 나사공 작업의 결과물의 품질을 극대화하기 위해서는 탭(4)의 가상 회전 중심축이 바람직하게 탭용 커넥터(10)의 가상 회전 중심축과 일치되도록 결합된다.In particular, in order to maximize the quality of the result of the threaded work to be machined without being shaken by the external power tool or manual tool, the virtual axis of rotation of the tab 4 is preferably the tab connector 10. Combined to coincide with the virtual axis of rotation.
또한, 고정볼트(14)의 내측 단부는 상기 탭(4)의 탭헤드(4a)의 모서리와 압입 고정되어 회전시 탭용 커넥터(10)와 탭헤드(4a)간에 마찰력을 극대화시켜 기존의 탭(4)을 가공할 필요없이 일체화됨으로써 슬립 현상을 방지하게 된다.In addition, the inner end of the fixing bolt 14 is press-fitted with the edge of the tab head (4a) of the tab 4 to maximize the friction force between the tab connector 10 and the tab head (4a) when rotating the existing tab ( By integrating without processing 4) slip phenomenon is prevented.
즉, 탭용 커넥터(10')는, 도4에서처럼 고정볼트(14)가 탭헤드(4a)가 아닌 다른 부위의 탭(4)에 압입 고정될 수 있지만, 도5에 도시된 바와 같이, 고정볼트(14')가 탭헤드(4a)의 모서리와 압입 고정될 수 있는 구성의 외면(12')을 가지도록 구성되어 별도의 전동공구(20)와 체결되면서 완벽하게 전동공구(20)의 회전력이 탭(4)으로 전달되어 간섭 현상이 일어나는 좁은 작업 공간에서도 슬립 현상없이 자동으로 고속 회전 탭 작업이 가능하게 된다.That is, in the tab connector 10 ', the fixing bolt 14 may be press-fitted to the tab 4 at a portion other than the tab head 4a as shown in FIG. 4, but as shown in FIG. 14 'is configured to have an outer surface 12' that can be press-fitted to the corners of the tab head 4a, and is coupled with a separate power tool 20, thereby completely rotating the power of the power tool 20. Even in the narrow working space where the interference occurs due to the tap 4, high-speed rotary tapping is possible without slipping.
이에 따라, 별도의 전동공구 또는 수동공구의 회전축 또는 연결구와 슬립 현상없이 회전력이 탭으로 전달되어 탭이 마모되거나 부러지고, 교체하는 등의 현상없이 작업의 효율성 및 생산성이 향상되고, 높은 품질의 탭 작업이 연속적으로 진행 가능하도록 하는 효과를 제공하게 된다.Accordingly, the rotational force is transmitted to the tap without any slipping phenomenon with the rotating shaft or the connector of a separate power tool or a manual tool, thereby improving the efficiency and productivity of the work without the phenomenon of wear, breakage or replacement of the tap. It provides the effect of allowing the work to proceed continuously.
