Embodiment
Now lift following examples and by reference to the accompanying drawings structure of the present invention and effect be described in detail.
As shown in FIG. 1 to 3, the pallet filler tool 10 for Spindle Motor that a preferred embodiment of the present invention provides includes a pedestal 20, and compresses part 30, dowel 40, thimble 50 and a spring part 60.
Pedestal 20 top side has blind hole 22 and three filler grooves 24 (as shown in Figure 5), each filler groove 24 is that isogonism is arranged at around blind hole 22 with distributing, filler groove 24 is formed by being located in a through hole 245 of pedestal 20 by accommodating member 241 plug, the open top periphery of through hole 245 is formed with lead angle or can be fillet, wherein, the end face of accommodating member 241 is formed with multiple chase 243.
Compress part 30 and be located at pedestal 20 by two guide pillars 32, and can move up and down along guide pillar 32, compress part 30 and have a guide hole 34, guide hole 34 coaxially extends with the blind hole 22 of pedestal 20.
Dowel 40 can be located at up or down and compress part 30, and has head 42 and a neck 44, and head 42 is arranged at the top side compressing part 30, and neck 44 is placed through and compresses in the guide hole 34 of part 30.
Thimble 50 and spring part 60 are placed in the blind hole 22 of pedestal 20, and spring part 60 is resisted against between the bottom of thimble 50 and blind hole 22.
Said modules is easy to processing or polishes, and is therefore beneficial to controlling dimension precision.
Pallet filler tool 10 for Spindle Motor is that cooperation one point gum machine (rubber dispenser) 14 uses (as shown in Figure 5), multiple rubber cushion 128 (as shown in Figure 6) can be formed on a pallet 12, pallet 12 includes housing 121 and a shaft member 125, housing 121 is in the form of annular discs, and there is an axis hole 122 and multiple perforation 123, wherein, the aperture of axis hole 122 is about slightly less than the external diameter of shaft member 125, make shaft member 125 can strut axis hole 122 a little and plug and be fixed in axis hole 122, each perforation 123 is positioned at around axis hole 122.
In addition, compress part 30 side and generally form each 123 positions of boring a hole that some vacant space make to correspond to respectively pallet 12, entering and exiting in order to point gum machine 14 in Y-shaped.
For the pallet filler tool 10 of Spindle Motor when reality uses, pallet 12 is placed on (as shown in Figure 4) above pedestal 20, wherein, housing 121 amplexiforms with the end face of pedestal 20, the position of each perforation 123 is corresponding with filler groove 24, shaft member 125 is then placed through in the blind hole 22 of pedestal 20, and abuts with thimble 50.Subsequently, compress part 30 and move down (as shown in Figures 1 and 3), until housing 121 by clamping in pedestal 20 and compress between part 30, now, the top side of pedestal 20 and pallet 12, and the surrounding compressing part 30 is formed with an open space.
Now, dowel 40 moves down along the guide hole 34 compressing part 30, and the shaft member 125 of simultaneously oppressing pallet 12 moves down along the axis hole 122 of housing 121, to adjust the relative position of housing 121 and shaft member 125 further.On the other hand, point gum machine 14 is movable to open space, and a macromolecular material 141 is directly injected the perforation 123 of pallet 12 and the filler groove 24 (as shown in Figure 5) of pedestal 20, subsequently, macromolecular material and curable and pallet 12 surface formed rubber cushion 128, finally remove pedestal 20 again and compress part 30, the filler program of pallet 12 can complete.
Because housing 121 and the assembling of shaft member 125 and the formation of rubber cushion 128 have all been come by tool 10, as long as the precision of tool 10 is enough, the verticality of rubber cushion 128 top surface and shaft member 125 can be grasped easily, and then improves the qualification rate of Spindle Motor finished product.In addition, the top side of pedestal 20 and pallet 12, and the surrounding's maintenance compressing part 30 is spacious, the movement helping point gum machine with aim at, moreover, there is between the housing 121 of pallet 12 and pedestal 20 gap 26 (as shown in Figure 5), thus for the air venting of filler groove 24 inside to extraneous, macromolecular material can be contributed to and fill up whole filler groove 24; Moreover the end face chase 243 of accommodating member 241 can make rubber cushion 128 form a rough surface, be conducive to driving disc.
In addition, compressing one of equivalent application embodiment of the guide hole 34 of part 30 can be a V-shaped groove, and the neck 44 of dowel 40 and the shaft member 125 of pallet 12, for abutting against in V-shaped groove, make the correspondence location, axle center of each parts.And the similar device of various three axles or multiaxis concentric locating etc., be also applicable to the present invention.
In addition, the thimble of previous embodiment 50 for supporting by spring part 60, but also can be changed to the embodiment cancelling spring part 60, changes into and thimble 50 is maintained constant height or utilize other assembly to control the lifting of thimble 50.
The above; be only detailed description and the diagram of preferred embodiment of the present invention; all embodiments meeting the spirit change similar with it of the present patent application the scope of the claims; all be included in category of the present invention; anyly be familiar with this those skilled in the art in the field of the invention, can think easily and change or modify all can be encompassed in scope of patent protection of the present invention.
