Title:
METHOD AND APPARATUS FOR ASSEMBLING CARRIAGE ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2007/063596
Kind Code:
A1
Abstract:
A method and an apparatus for assembling a carriage assembly are provided to set
a suspension more precisely than conventionally to a carriage arm without deformation,
so that dispersion of their magnetic head floating characteristics is suppressed
and better information writing and reading characteristics are installed in
them. A receiving hole (10a) made in a carriage arm (10) is aligned with a spacer
hole (12b) made in spacer member (12a), a suspension (12) is assembled with the
carriage arm (10), a rod-like functioning member (22) with an external diameter
that is less than an internal diameter of the spacer hole (12b) is inserted into
the spacer hole (12b), expanding and contracting movement of the rod-like functioning
member (22) is made in the radial direction by applying axial ultrasonic vibrations,
and the functioning member (22) hits and rivets a spacer-hole circumferential
portion (13) of the spacer member (12a) to fix the suspension (12) to the carriage
arm (10) thereby when the functioning member (22) is extended in diameter.
