| description | The present invention relates to a method of restoring a damaged thread of a cylinder head to couple an ignition plug thereto and, more specifically, to a method of restoring a damaged thread, coupling an implant thereto, and installing again an ignition plug when the thread of a cylinder head having the ignition plug inserted thereinto is damaged or lost due to accumulated carbon and thermal deformation not to be used, such that expenses for replacing the entire cylinder head can be reduced. According to the present invention, the method comprises: a reaming step of rotating a drilling tool having a drill coupled thereto on a squashed thread after removing an ignition plug from a screw hole of a cylinder head to cut the squashed thread so as to ream the screw hole; a grinding step of grinding the inner surface of the reamed screw hole with a grinding tool having a grinding device coupled thereto; a thread forming step of rotating a screw tap device having a screw tap coupled thereto after grinding the screw hole to form a new thread on the inner surface of the screw hole; an implant coupling step of forming a steel implant having a thread formed on inner and outer diameters and screw-coupling the implant in the screw hole of the cylinder head; and an ignition plug coupling step of removing an implant rod from the inner thread of the implant and screw-coupling a thread of the ignition plug thereto.
본 발명은 실린더 헤드의 손상된 나사산을 복원하여 점화 플러그를 결합하는 방법에 관한 것으로 더욱 상세하게는 점화플러그가 삽입된 실린더 헤드의 나사산이 누적된 탄소와 열변형으로 손상이나 훼손되어 사용할 수 없을 때, 이를 복원하여 보형물을 체결한 후에 점화플러그를 다시 설치할 수 있도록 하므로 실린더 헤드 전체를 교체하는 비용을 줄일 수 있는 것이다. 이는 본 발명은 실린더 헤드의 나사공에서 점화 플러그를 탈거한 후에 뭉개진 나사산에 드릴이 체결된 드릴 공구를 회전시키면서 나사산을 절삭하여 확공하는 확공단계와, 상기 확공된 나사공의 내면을 면취구가 체결된 면취 공구를 이용하여 면취하는 면취단계와, 상기 나사공을 면취한 후에 나사탭이 체결된 나사탭 공구를 회전시키면서 나사공의 내면에 새로운 나사산을 형성하는 나사산 형성단계와, 상기 나사산이 형성된 나사공에 결합되며, 내경과 외경에 나사산이 형성된 스틸 보형물을 형성하고, 스틸 보형물의 내경에 보형물 로드를 나사 결합한 후, 실린더 헤드의 나사공에 보형물을 나사 결합하는 보형물 결합단계와, 상기 보형물의 내경 나사산에서 보형물 로드를 제거한 후에 점화플러그의 나사산을 나사 결합하는 점화 플러그 결합단계로 이루어진 것을 특징으로 한다. |
