Description
Technical field
The invention relates to a kind of automatically oiling device that is used for screw rod, especially a kind of automatically oiling device that is used for the CD drive screw rod.
Background technology
Along with the PC fast development, also growing up fast in the market of computer peripheral product, such as computer peripheral products such as hard disk drive, CD drive, scanner, printers, has all become the instrument of modern offices indispensability.And in these computer peripheral products, CD drive is the storing media that generally uses at present.CD drive more provides the benefit of diversified storage data form and data long preservation except great storage volume can be provided.Particularly (Digital Versatile Disc, development DVD) provide up to the storage volume of 17GB and more high-quality image and audio output, and make that the application of CD drive is more extensive along with Digital video disc of new generation.
Please refer to shown in Figure 1ly, be presented in the typical light disk drive framework, have one and drive the Spindle Motor 100 and of discs rotation in order to read the optical R/W mechanism of discs data.Wherein, optical R/W mechanism comprises a slide rail 220, a CD-ROM drive motor (not shown), a lead screw 240 and an optical R/W module 260.Slide rail 220 is to be parallel to each other with lead screw 240, and is stretched out by the position of Spindle Motor 100.Optical R/W module 260 is to sleeve to slide rail 220 and be screwed together in lead screw 240, and simultaneously, CD-ROM drive motor is that an end that is connected in lead screw 240 rotates to drive lead screw 240, uses driving optical R/W module 260 is made linearity along slide rail 220 setting movement.
Please refer to shown in Fig. 2 A and the 2B, is the screw-joining structure that amplifies 260 of lead screws 240 and optical R/W module in the displayed map 1.As shown in FIG., the side of optical R/W module 260 has a U type supporting construction (rack) 280, and has the screw thread 242 that screw thread 282 is engaged to lead screw 240 surfaces in the opening of this U type supporting construction 280.Simultaneously, the side of this U type supporting construction 280 is the motion dimensions that limited optical R/W module 260, optical R/W module 260 only can be moved linearly along lead screw 240, therefore, lead screw 240 is passed to the rotating torque of optical R/W module 260, can be converted to linearly moving driving force smoothly.
Generally speaking, for above-mentioned U type supporting construction 280 can be screwed togather glidingly to lead screw 240, to avoid influencing the location of optical R/W module 260, must impose in advance on the lead screw 240 lubricated, to reduce the frictional resistance between U type supporting construction 280 and the lead screw 240.By this lubrication operation,, simultaneously, also can reduce CD-ROM drive motor and drive the required driving force of optical R/W module 260 except avoiding between U type supporting construction 280 and the lead screw 240 producing the stuck phenomenon of screw thread.
Please refer to shown in Figure 3ly, is the synoptic diagram of a typical lead screw oiling device 300.As shown in FIG., an end of lead screw 240 be predetermined fixed on CD-ROM drive motor 340, and the two is to be positioned in the lump on the base 320.Above base 320, other has a fueller 360 movably, can move down so that lubricating oil is annotated on lead screw 240, and this fueller 360 also can move along the axial work of lead screw 240 is linear.When carrying out the step that lead screw 240 oils, CD-ROM drive motor 340 must be alived driving lead screw 240 rotations, and fueller 360 by top coating lubricating oil on lead screw 240, the end by lead screw 240 moves to the other end simultaneously.By the mutual motion of 360 of above-mentioned lead screw 240 and fuellers, can guarantee that lubricating oil can cover the surface of lead screw 240 fully.
As described above, traditional lead screw oiling device 300 is covered in the surface of lead screw 240 fully in order to ensure lubricating oil, must be that predetermined fixed is on CD-ROM drive motor 340 with an end of lead screw 240, in the step that oils, also need to be energized to CD-ROM drive motor 340 simultaneously to drive lead screw 240 rotations.Therefore, not only make the design of lead screw oiling device more complicated, simultaneously, also make the step that oils more complicated.
In addition, because lead screw is with the screw-in version transferring power, therefore, the screw thread on lead screw surface is to need most lubricated position.Yet the step that oils of aforementioned conventional only can oil to lead screw comprehensively, and can't oil at screw thread, therefore, and except meeting causes the waste of lubricating oil, simultaneously, also easily because of oiling inequality, and the phenomenon of generation lack of lubrication.
The whence is, how to provide effectively, oiling device is in the CD drive assembling process to guarantee that lead screw can effectively lubricating easily, a considerable problem.
Summary of the invention
Fundamental purpose of the present invention provides a kind of lead screw oiling device, and its lead screw to be oiled must predetermined fixed can not oil on CD-ROM drive motor, uses the design of simplifying the lead screw oiling device and the step that oils.
Another object of the present invention provides a kind of lead screw oiling device, can be effectively partly oils at the screw thread of lead screw, and improving the lubricant effect of lead screw, and, the use that can save lubricating oil.
Automatically oiling device of the present invention comprises a screw bolt seat, movably drive division, an oil feeder and a drive unit.Wherein, screw bolt seat is in order to carrying and location screw rod to be oiled, and movably drive division is the top that is positioned at screw bolt seat, in order to mesh screw rod so far.Oil feeder is to be fixed on the drive division, and has a pump nozzle and extend in the screw flight.Drive unit is to be positioned on this screw bolt seat, and this drive unit drives this drive division makes this drive division move along the axial work of this screw rod is linear.After drive division was engaged in screw rod, drive division moved along the axial work of screw rod is linear, drive screw rod simultaneously and rotate, and make pump nozzle along screw flight move and oiling in wherein.
For moving of controlling and driving portion, in one embodiment of this invention, on screw bolt seat, install two-dimentional drive unit, make with the drive drive division to be screwed together in screw rod downwards, in addition, also drive drive division and make along the axial work of screw rod linear mobile.
In one embodiment of this invention, movably drive division is to have a downward opening to hold screw rod, simultaneously, has internal thread in this opening to be engaged on the screw rod.
In one embodiment of this invention, movably drive division is a flank of tooth tooth bar down, and its flank of tooth is to be engaged to screw flight.
For further specifying above-mentioned purpose of the present invention, design feature and effect, the present invention is described in detail below with reference to accompanying drawing.
