Magnetic head assembly positioning structure

Abstract

This invention discloses a localization structure of a head component including a head component, a disk base and a fastening component, in which, the head component includes a shaft set and a head, the shaft set includes a shaft, a bearing and a shaft jacket, said disk base includes a top surface and a lower surface, a convex desk protruding from the top surface of the base and a ladder slot set through the top surface of the convex desk and the lower surface of the disk base, said fastening part includes a coaxial localization stand and a pole with screw threads, the shaft has a screw hole, the head component is set on the top of the convex desk, the localization desk of the fastening part is localized in the slot, the pole part passes through the ladder slot to the top from the bottom to match with the screw of the hole of the shaft.

Description

technical field

[0001] The invention relates to the field of hard disks, in particular to a positioning structure of a magnetic head assembly. Background technique

[0002] The existing hard disk includes a hard disk base and a magnetic head assembly installed on the hard disk base. The magnetic head assembly includes a rotating shaft set and a magnetic head. The rotating shaft set includes a rotating shaft, a bearing and a rotating shaft sleeve. The inner ring of the sleeve is fixedly sleeved on the outer ring of the bearing, while the magnetic head is fixedly sleeved on the outer ring of the rotating shaft sleeve, and the rotating shaft is fixedly installed on the hard disk base. However, the existing hard disk has the following disadvantages: the rotating shaft is locked on the hard disk base by a screw loaded from the front of the hard disk base, thereby requiring a larger installation space, and then increasing the volume of the entire hard disk, which does not meet Th...
