Abstract

The utility model relates to a main axle motor fixing device for an optical disc player core. The main axle motor fixing device mainly comprises a player core base, wherein, the player core base is provided with a hole with a flange, the hole with a flange is formed by punching, the outside of the flange is sheathed with a circuit board and is attached with the player core base, a main body of the main axle motor is positioned on the circuit board, a bearing of the motor is inlaid in the hole with the flange of the player core base, a silicon steel sheet of the stator of the motor is fixed outside the hole with the flange, and the end section of the bearing is provided with a bottom cover of the motor to seal the bearing of the main axle motor. Because the flange which is arranged by the player core base can replace the bearing sleeve section of the ordinary motor, materials can be saved, and the cost of products can be reduced. The main axle motor, the circuit board and the player core base are combined as integration without riveting, and the installing technologies can be reduced. The vertical straightening of a rotating shaft can not be needed when an optical disc player is assembled, the deflection errors of optical discs which are supported on the main axle motor of the optical disc player can be reduced, and the installing positioning errors of the main axle motor can be reduced.

Description

The Spindle Motor stationary installation of laser disc movement

Technical field

The utility model is a kind of Spindle Motor stationary installation of laser disc movement.

Background technology

The movement of CD-ROM device, space structure is less, the installation of its Spindle Motor is subjected to the restriction of its space structure, generally PCB circuit board and Spindle Motor are positioned at the one installation, concrete mounting means is, on circuit board, make a call to a hole, on motor bearing, overlap upper bearing sleeve, motor shaft end is passed circuit board, bearing holder (housing, cover) is riveted on the motor fixed plate, to rivet good motor fixed plate again and be installed on the movement pedestal, and all be provided with corresponding hole confession motor drive shaft in motor fixed plate and movement pedestal corresponding position and pass.The another kind of prior art relevant with the utility model is that the bearing holder (housing, cover) that will pass the Spindle Motor of circuit board directly is riveted on the movement pedestal, and saved motor fixed plate.These two kinds of mounting meanss, all the bearing of motor is provided with bearing holder (housing, cover), and this bearing holder (housing, cover) generally adopts copper material, costs an arm and a leg.And, because the setting of bearing holder (housing, cover) needs complex installation technology could guarantee installation accuracy,, just can guarantee the normal operation of Spindle Motor at last in order to reduce to install the cumulative errors that causes.

The utility model content

The technical problems to be solved in the utility model is, a kind of Spindle Motor stationary installation of laser disc movement is provided, and this stationary installation has been saved the bearing holder (housing, cover) of Spindle Motor, and is simple in structure, save starting material, and can improve the cumulative errors that forms in the Spindle Motor assembling process.

The utility model provides following technical scheme, a kind of Spindle Motor stationary installation of laser disc movement, mainly comprise the movement pedestal, this movement pedestal is provided with the hole of the band flange that forms through punching press, and flange is with circuit board outward, and fits with the movement pedestal, the Spindle Motor main body is positioned on the circuit board, its motor bearing is installed in the hole of movement pedestal band flange, and the stator silicon steel plate of motor is fixed on outside the flange hole, and is provided with the motor bottom with its bearing spindle motor sealing in the bearing end.

This movement pedestal is at fixed main shaft motor place, be provided with the hole of band flange, circuit board also is provided with a through hole, board sleeve is outside flange, and fit with this movement pedestal, because this flange has substituted the bearing holder (housing, cover) part of common motor, saved material, reduced cost of products, make this Spindle Motor and circuit board and this movement pedestal need not rivet and be integral, reduce mounting process, when CD-ROM device is assembled, need not carry out the rotating shaft vertical correction, reduced the Run-out error of the CD-RW discsCD-RW of being carried on the CD-ROM device Spindle Motor.

Below in conjunction with accompanying drawing the utility model is elaborated.
