Description

실린더블록의 헤드볼트구멍 재생용 인서트 암나사볼트 및 그 볼트 시공용 공구{Insert internal thread bolts for head bolt hole regeneration in cylinder block and tools for bolt construction}Insert internal thread bolts for head bolt hole regeneration in cylinder block and tools for bolt construction

본 발명은 자동차의 엔진을 구성하는 실린더블록에 실린더헤드를 헤드볼트로 체결하기 위하여 실린더블록에 형성된 암나사구멍이 파손되어 그 기능이 상실되었을 때 암나사구멍을 재생하기 위한 실린더블록의 헤드볼트구멍 재생용 인서트 암나사볼트 및 그 볼트 시공용 공구에 관한 것이다.The present invention relates to a head bolt hole regeneration of a cylinder block for regenerating a female screw hole when a female screw hole formed in the cylinder block is damaged and its function is lost in order to fasten a cylinder head to a cylinder block constituting an engine of an automobile with a head bolt It relates to an insert female screw bolt and a tool for bolt construction.

주지하는 바와 같이 자동차의 엔진은 실린더블록에 실린더헤드를 헤드볼트로 체결되어 있는데, 최근에 자동차의 경량화 추세와 소재기술이 발전하면서 알루미늄 합금으로 제조된 실린더블록 및 실린더헤드가 개시되고 있다.As is well known, the engine of a car is fastened with a cylinder head to a cylinder block with a head bolt. Recently, as the weight reduction trend and material technology of automobiles develop, a cylinder block and cylinder head made of aluminum alloy are disclosed.

상기한 알루미늄합금 소재로 제조된 실린더블록은 실린더 내부에 연료가 피스톤에 의해서 흡입되어, 압축되고, 폭발되어, 배기되는 작용을 반복하는 과정에서 발생하는 고온에 의해서 수축과 팽창이 반복된다.The cylinder block made of the aluminum alloy material is repeatedly contracted and expanded by the high temperature generated in the process of repeating the action of fuel being sucked into the cylinder by a piston, compressed, exploded, and exhausted.

상기와 같이 실린더블록이 열에 의해서 수축과 팽창이 반복되면, 실린더블록에 형성된 암나사구멍도 수축과 팽창이 반복되면서 암나사구멍에 체결된 팽창계수가 다른 금속볼트와 마찰을 반복하여 상대적으로 약한 실린더블록에 형성된 암나사구멍의 나사산이 파손되어 실린더블록과 실린더헤드 사이에 엔진오일이 유출되는 사례가 빈번하게 발생하였다.As described above, when the cylinder block contracts and expands repeatedly due to heat, the female screw hole formed in the cylinder block is also contracted and expanded repeatedly, and friction with the metal bolts with different expansion coefficients fastened to the female screw hole is repeated, resulting in a relatively weak cylinder block. There were frequent cases of engine oil leaking between the cylinder block and the cylinder head as the threads of the formed female screw holes were broken.

상기와 같이 실린더블록에 형성된 암나사구멍의 나사산이 파손되어 헤드볼트 체결력이 상실되면, 암나사구멍의 나사산을 재생해서 사용하게 되는데, 종래에는 실린더블록에 형성된 암나사구멍을 드릴로 가공하여 헬리코일을 체결하고, 상기 헬리코일에 헤드볼트를 체결하는 것으로 실린더블록에 실린더헤드를 고정하였다.As described above, when the screw thread of the female screw hole formed in the cylinder block is damaged and the head bolt fastening force is lost, the screw thread of the female screw hole is regenerated and used. , The cylinder head was fixed to the cylinder block by fastening the head bolt to the helical coil.

그런데, 파손된 암나사구멍에 드릴로 구멍을 가공하고 탭을 형성하는 과정에서 센터를 정확하게 잡아줄 수 있는 공구가 없기 때문에 구멍에 헬리코일을 정확하게 체결할 수 없을 뿐만 아니라, 헬리코일의 암나사산의 규격이 실린더헤드를 실린더블록에 체결하기 위한 헤드볼트의 나사산과 잘 맞지 않기 때문에 헤드볼트 체결력이 떨어지는 문제가 있다.However, since there is no tool that can accurately hold the center in the process of drilling a hole in the damaged female threaded hole and forming a tap, it is not possible to accurately fasten the helical coil to the hole, as well as the specifications of the female thread of the helical coil. Since the thread of the head bolt for fastening the cylinder head to the cylinder block does not match well, there is a problem in that the head bolt fastening force is lowered.
