ABSTRACT:
An apparatus for tightening connecting rod attachment members comprises a rotating mechanism for rotating and positioning a crankshaft about a center of its shaft section, angular deflecting mechanisms for deflecting nut runners about the center of the shaft section, axial displacement mechanisms for displacing the nut runners in an axial direction of the crankshaft, and inter-axis displacement mechanisms for making mutual approach or separation for a distance between the pair of nut runners and a distance between the pair of nut runners. The nut runners are operated to fasten a connecting rod to the crankshaft. Accordingly, one tightening apparatus can be used to tighten the connecting rod attachment members to the crankshaft even when the type of the crankshaft is changed. The tightening apparatus is applicable to a production line for carrying multiple types in a mixed manner.
