Method for press-in attachment of suspension assembly in hard disk drive

摘要

A method of and apparatus for assembling a disk drive. The method comprises steps of clamping a number of head suspension assemblies in an actuator body such that base plate hubs in the suspensions are in alignment with corresponding boss holes in actuator arms extending from the actuator body, inserting closed jaws between the actuator arms and in alignment with the base plates, and opening the jaws a reach sufficient to urge each base plate hub into a corresponding boss hole. The jaws are opened by any suitable mechanism, for example by driving a wedge in between the closed jaws. A novel apparatus is employed for joining base plate hubs to actuator arms extending from an actuator body. The apparatus includes an actuator body clamp adapted to hold a number of suspensions in the actuator body, with hubs of the suspensions in alignment with boss holes in the actuator arms. A jaw shaped tool fitted to dimensions of spaces between the actuator arms and a wedge shaped tool having appropriate dimensions so as to open the jaws are employed. The jaws have a reach sufficient to urge a base plate hub into an actuator arm boss hole.
