Method of calking cylindrical member in hole |
摘要 |
A cylindrical member is placed in a dead-end hole formed in a housing made of a material such as aluminum. A peripheral portion of the hole is pressed down to plastically deform the housing material and to supply the deformed material into a groove formed on an outer periphery of the cylindrical member. The cylindrical member is calked to the housing in this manner. To supply a proper amount of deformed material into the groove for obtaining a quality calking, an inflection point of a calking curve indicating a relation of a calking force and a calking stroke is detected during the calking process. After the inflection point is detected, the calking is performed by giving a predetermined calking stroke or by adding a predetermined calking force.
