Claims
- 1. An apparatus for assembling disc drive motor components, comprising:(a) a readily removable frame piece for mounting on a base piece; said frame piece having a plurality of retractable guide shafts for holding a plurality of motor components, said guide shafts having a plurality of tensioning springs positioned coaxially with said guide shafts for compressively tensioning said plurality of motor components; and (b) a bushing means for securing said plurality of guide shafts to said frame piece, said frame piece having a coupling means for positioning said frame piece on said base piece, said base piece having a plurality of motor component nests, said base piece having a support means for mounting the coupling means of said frame piece in operative combination with said plurality of motor component nests, said base piece having a means for inserting and retracting said plurality of guide shafts of said frame piece, and said base piece having an overgramming means for applying overgramming pressure to said plurality of frame guide shafts.
- 2. An apparatus as in claim 1, wherein said frame coupling means further comprises: pins for positioning said frame on the support means of the base; and said base piece frame support means having a raised surface with a notch for engaging said pins of frame piece, whereby the frame is in operative combination with said plurality of motor component nests of said base.
- 3. An apparatus as in claim 1, wherein said bushing means further comprises:a brass bushing; said brass bushing adjustable by a screw accessed through said frame piece.
- 4. An apparatus as in claim 1, further comprising means for clamping said frame piece to said base piece,wherein said clamping means comprises: a clamp having an edge; and a rubber boot mounted on said edge for firmly securing said frame piece to said base piece.
- 5. The apparatus of claim 4, wherein said clamp further comprises:a clamp shaft, said clamp shaft having a cam; and a pneumatic piston for raising and lowering said clamp shaft while said shaft is rotated 90° by said cam, thereby allowing easy insertion or removal of said frame piece.
- 6. An apparatus as in claim 1, wherein said overgramming means further comprises:a plurality of overgramming pistons for pressing against said plurality of guide shafts.
- 7. An apparatus as in claim 1, wherein said inserting and retracting means further comprises:a single retractor bar for simultaneously engaging said plurality of guide shafts, said retractor bar operated by a piston for inserting and retracting said plurality of guide shafts.
- 8. An apparatus as in claim 7, wherein said inserting and retracting means further comprises:a retractor bar with a plurality of notches for engaging said plurality of guide shafts, said plurality of guide shafts having recesses for engaging the plurality of notches of said retractor bar.
