A hard disk dismounting auxiliary device

Abstract

The invention discloses a hard disk dismounting auxiliary device. The hard disk dismounting auxiliary device is characterized in that involute surface patches which are in the shapes of cantilevers are arranged on a rotary shaft in a sleeving mode, wherein the involute face patches which are axially arranged in a spaced mode and are positioned at the same central angles form an involute surface patch set; an axial spacing between the two involute surface patches in the same involute surface patch set is greater than a thickness of a hard disk and smaller than a spacing between two magnetic heads in one magnetic head set; the two involute surface patches in the same involute surface patch set can synchronously rotate along with the rotary shaft; by virtue of the involute surface patches, an arc-line side of a fan-shaped surface patch is set to be an involute side; and the rotary shaft is rotated, so that a pair of involute surface patches in the involute surface patch set, along the involute side, can be gradually switched to a position between the two magnetic heads in the same magnetic head set, and the two magnetic heads are synchronously lifted away the surface of the hard disk. The hard disk dismounting auxiliary device, which has very high requirements on a dismounting process of a computer hard disk and a magnetic head assembly, is used for maintaining the computer hard disk.

Description

technical field [0001] The invention relates to an auxiliary device for assembly and disassembly of a mechanical mechanism, more specifically, a device that can be used for assembly and disassembly between the magnetic head of a computer hard disk drive and the disc of a computer hard disk drive, and for implementing precise assembly between similar two components with disassembly aids. Background technique [0002] Computer hard disk drive, referred to as hard disk, is a computer device that combines machinery and electronics and is used to store electronic information. The hard disk is mainly composed of information recording components, namely hard disk discs, read and write components, namely hard disk heads, control circuits and casings. [0003] The magnetic head of the hard disk is supported by an elastic cantilever, and is in an elastic assembly relationship with the hard disk disc. In this way, the magnetic head is suspended above the disc by the airflow generated ...

AI Technical Summary

Problems solved by technology

[0011] 1. It is difficult to lift the magnetic head from the hard disk in micron size and control its deformation within the limit value;

[0012] 2. It is difficult to lift the magnetic head from the hard disk at the same time in micron size;

[0013] 3. In the process of removing the magnetic head assembly from the hard disk, it is difficult to ensure that the lifting amount of all the magnetic heads does not change beyond the limit and fall;

[0014] Third, some of the characteristics of hard disk heads and hard disk platters are as described above. The personnel who need to perform maintenance work have rich technical experience and complete and accurate operation accuracy, which objectively limits the number of such technicians and forms such a The current situation of talent shortage restricts the popularization of this technology
