Embodiment
See also Fig. 2 to Fig. 9, hard disk of the present invention comprises base 1, first disc 2, cushion block 3, second disc 4, briquetting 5 and securing member 6.
See also Fig. 3 and Fig. 9, this base 1 is provided with disc rest area 7 and head stack installing zone 18, and the center of this disc rest area 7 is equipped with columniform bearing motor 9, and this head stack installing zone 18 is equipped with head stack 19 and magnetic patch assembly 30.
See also Fig. 4, this bearing motor 9 has a smooth top surface 16, the recessed groove 10 that is formed with of axis direction from the middle position of this top surface 16 along this motor 9, middle position from this groove 10 extends positioning boss 11 straight up along this axis direction, and the top surface 111 of this positioning boss 11 exceeds the top surface 16 of this motor, and the middle position of these positioning boss 11 top surfaces 111 has threaded hole 12 along this axis direction certainly.In addition, the top surface 16 of this motor 9 also has four locating slots 14, these four locating slots 14 be evenly distributed on this groove 10 around.
See also Fig. 5, briquetting 5 is the circular metal plate of integrated punching moulding, and the external diameter of this briquetting 5 is slightly larger than the diameter of this cylindrical motor 9.Briquetting 5 arches upward to the center gradually from its outer rim 17, and this outer rim 17 is handled through flange.The middle position punching press of this briquetting 5 is formed with a shoulder hole that runs through, and has also gone out four equally distributed pilot holes 22 around this shoulder hole.This shoulder hole is by being connected and the spacing hole 20 and the storage tank 21 of coaxial cable are formed, and this spacing hole 20 is positioned at storage tank 21 belows, and there is a step surface 15 in its aperture less than the groove footpath of storage tank 21 between this spacing hole 20 and storage tank 21.The aperture of spacing hole 20 is slightly larger than the external diameter of the positioning boss 11 of motor 9, and this spacing hole 20 equates with the centre distance of the locating slot 14 of motor 9 with the threaded hole 12 of motor 9 with the centre distance of pilot hole 22.
See also Fig. 6 and Fig. 7, securing member 6 comprises bar portion 24, and the upper end of this bar portion 24 is provided with head 23 one-body molded with it and that diameter is bigger, and the lower end of this bar portion 24 is processed with screw thread 27.Axis direction from the middle position of these head 23 top surfaces along this securing member 6 has spin slot 25 downwards.Axis direction from the basal surface of this head 23 along this securing member 6 extends locating ring 26 downwards, and this locating ring 26 is around this bar portion 24, and the thickness of this locating ring is not less than 0.3mm, and it highly is not less than 0.2mm.The internal diameter of this locating ring 26 is slightly larger than the external diameter of positioning boss 11, and the external diameter of this locating ring 26 is slightly less than the aperture of the spacing hole 20 of briquetting 5.
During the assembling hard disk, at first first disc 2, cushion block 3 and second disc 4 are enclosed within on the motor 9 in turn; Then securing member 6 is passed the spacing hole 20 of briquetting 5, the head captured that makes this securing member 6 is in storage tank 21 and be bearing on the step surface 15, and this briquetting 5 is put on the motor 9 together with this securing member 6, screw thread 27 parts of bar portion 24 are stretched in the threaded hole 12 of motor, at this moment, the locating ring 26 of securing member 6 is stuck between the hole wall of the positioning boss 11 of motor 9 and spacing hole 20; Then rotate briquetting 5, make four pilot holes 22 of briquetting 5 aim at four locating slots 14 of motors 9, tweezers or other aids are passed pilot hole 22 and be stuck in the locating slot 14; Snap in spin slot 25 with screwdriver or other aids more at last, turn Fastener 6 makes threaded hole 12 threaded engagement of screw thread 27 with the motor of bar portion 24, thereby this briquetting 5 is installed on this motor 9.
See also Fig. 8, tighten screw after, locating ring 26 is stuck between the hole wall of the outer wall of positioning boss 11 and spacing hole 20, and the outer wall clearance fit of the inner ring of this locating ring 26 and positioning boss 11, the hole wall clearance fit of the outer ring of this locating ring 26 and spacing hole 20; Head 23 is pressed on the step surface 15 of briquetting 5, and the outer rim 17 of briquetting 5 is pressed on second disc 4.
Because locating ring 26 is stuck between the hole wall of positioning boss 11 and spacing hole 20, the axis of locating ring 26 both with the axis of positioning boss 11---be the dead in line of motor 9, also with the axis of spacing hole 20---be the dead in line of briquetting 5, thereby make the axis of briquetting 5 keep overlapping with the axis of motor 9, and then motor 9 is when rotating, briquetting 5 can eccentric rotary, in the time of can reducing hard disk work greatly because of the caused vibration of axis runout of the axis and the briquetting 5 of motor 9.
