Abstract
An index-feed machining system having a pilot machining device for sequentially forming pilot portions on a workpiece indexed at predetermined pitches, a pilot guide means engaging with the pilot portions, and a plurality of independent machining means corresponding to a plurality of machining processes; all of these means being sequentially disposed in the feeding direction of workpiece; in which the pilot machining means and the pilot guide means are constructed integrally. The index-feed machining system lends itself to the easy positioning of machining means, and to the manufacture of high-precision products.
Claims10
An apparatus for machining a workpiece, the apparatus comprising:
- means for indexing the workpiece at predetermined pitches;
- pilot means for sequentially providing pilot portions on the workpiece;
- pilot guide means integrally formed with said pilot means and for engaging with said pilot portions;
- a base plate defining a dovetail groove in a feeding direction, said base plate also including a threaded shaft fixedly fitted to said base plate in a direction parallel with said dovetail groove;
- a plurality of independent machining means for performing a corresponding plurality of machining processes being sequentially performed in accordance with said indexing of the workpiece and using said pilot portions as references, each of said plurality of machining means including a dovetail engaged with said dovetail of said base plate, said machining means being movably and positionably guided by said dovetail groove, said each of said plurality of machining means including a driving spiral gear rotatably fitted to said each of said plurality of machine means;
- a plurality of driven spiral gears threadably engaged with said threaded shaft, one of each of said plurality of driven spiral gear meshing with one of said driving spiral gears, said plurality of machining means including connection means for independently moving said each of said plurality of machining means with said driven spiral gear as said each of said driven spiral gears move along said threaded shaft, said driven spiral gears moving along said threaded shaft by rotating about said threaded shaft, and said driving spiral gear rotating said driven spiral gear.
An apparatus for machining a workpiece, the apparatus comprising:
