PRODUCTION DEVICE FOR CONNECTING ROD
Document Type and Number:
WIPO Patent Application WO/2008/072450
Kind Code:
A1
Abstract:
A set of bolt holes (42a, 42b) through which bolts are inserted are formed in left
and right sides of a large end section (38). The bolt holes (42a, 42b) are substantially
parallel to the axis of a rod section (34) and are located such that the centers
of the bolt holes (42a, 42b) are each displaced from the center of a cut surface.
When a first mandrel (114) and a second mandrel (120) are press fitted to a joint
hole (36) of the large end section (36) and are cut and split, the area of contact
of the second mandrel (120) on the movable stage (64) side with the inner wall of
the joint hole (36) is set greater than the area of contact of the first mandrel
(114) on the fixed stage (62) side with the inner wall of the joint hole (36).
