A method of assembling a carriage assembly is capable of suppressing deformation of spacer portions when suspensions are attached to carriage arms. The method of assembling a carriage assembly aligns fitting holes provided in front end portions of carriage arms and spacer holes provided in spacer portions of suspensions and places the suspensions onto the carriage arms, and then presses a ball with a diameter equal to or greater than an inner diameter of the spacer holes with a pressure-applying member to pass the ball through the spacer holes, thereby crimping spacer hole edge portions of the spacer portions and attaching the suspensions to the front end portions of the carriage arms. By applying ultrasonic vibration from two axial directions to the pressure-applying member, the pressure-applying member is caused to vibrate on a two-dimensional movement path on a predetermined plane and passes the ball through the spacer holes while causing the ball to rotate.

The ultrasonic crimping apparatus of the invention includes: a supporting section that supports a crimped object having a crimped section with a through hole formed therein; a crimping member in a bar shape that is smaller toward a front end thereof and larger toward a rear end thereof; a driving section that causes the crimping member to be inserted in the through hole, first from the front end thereof; an ultrasonic application section that applies ultrasonic wave to the crimping member, thereby causing radial displacement of the crimping member; and a crimping control section that causes the crimping member to be inserted into the through hole of the crimped object, while causing application of ultrasonic wave to the crimping member, thereby causing the crimped section of the crimped object to be crimped.

When crimping suspensions to carriage arms using a metal ball by applying ultrasonic vibration to a crimping tool, the suspensions can be crimped to the carriage arms without causing deformation to the suspensions and the like. A method of assembling a carriage assembly aligns attachment holes provided in front ends of carriage arms and crimping portions provided on suspensions to set the suspensions on the carriage arms and then presses a ball through crimping holes provided in the crimping portions while applying ultrasonic vibration to the crimping tool to crimp the suspensions to the carriage arms. When doing so, a ball, such as a ball whose surface has been subjected to a dimpling process, for which a load that acts on the ball when the ball passes through the crimping holes is low compared to a spherical ball is used to crimp the suspensions to the carriage arms.

A method of assembling a carriage assembly and an assembling apparatus that uses the same are capable of suppressing fluctuation in the crimped (deformed) states of spacer portions when suspensions are attached to carriage arms. The method of assembling a carriage assembly aligns fitting holes 10a provided in carriage arms 10 with spacer holes 12b of suspensions 12 and then passes a ball 20 with a diameter equal to or greater than an inner diameter of the spacer holes 12b through the spacer holes 12b to crimp edge portions of the spacer holes 12b in spacer portions 12a and thereby attach the suspensions 12 to the carriage arms 10. While the ball 20 is being pressed and sandwiched from both sides of the spacer holes 12b by two pressure-applying members 40a, 40b and ultrasonic vibration is applied to the two pressure-applying members 40a, 40b, the two pressure applying members 40a, 40b are moved so as to pass the ball 20 through the spacer holes 12b.

A method of assembling a carriage assembly that is operable, during a crimping step that passes a ball, which has a diameter that is equal to or larger than an inner diameter of spacer holes of suspensions, successively through the spacer holes using a bar-shaped pressing member that is subjected to ultrasonic vibration to thereby crimp spacer hole inner circumferential portions of the spacer portions and attach the suspensions to the front end portions of the carriage arms, to prevent the pressing member that presses the ball from colliding with an inner circumferential surface and the like of the spacer holes of the spacer portions and is therefore able to substantially eliminate tilting from the standard angle of the suspensions due to deformation of the spacer portions, and an assembling apparatus that uses such method are provided.After the ball 20 has passed through one of the spacer holes 12b, the inner diameter of the through-hole 36a of the gap maintaining plates 36 positioned to the rear of such spacer hole 12b in the direction in which the ball 20 passes is reduced to a smaller diameter than the inner diameter of the spacer holes 12b.

The suspensions are crimped to the carriage arms by detecting stress that acts on the crimping tool when the metal ball is pressed in by the crimping tool and controlling the amplitude of the ultrasonic vibration applied to the crimping tool so as to increase and decrease in accordance with the magnitude of the stress.
