Abstract
A workpiece machining system for simultaneously machining the opposite surfaces of workpieces such as discs for disc brakes includes at least two machining apparatus disposed on a workpiece transfer path between a first workpiece inlet conveyor line and a second workpiece outlet conveyor line, for machining respective workpieces while holding and rotating the workpieces in the same attitude as that in which they are conveyed along the first and second conveyor lines. The workpiece machining system also includes a transfer apparatus for transferring the workpieces from the first conveyor line through the machining apparatus to the second conveyor line while maintaining the workpieces in the same attitude.
Claims8
A workpiece machining system comprising:
- a first workpiece inlet conveyor line;
- a second workpiece output conveyor line;
- at least two machining apparatus disposed on a workpiece transfer path between said first and second conveyor lines, for machining respective workpieces while holding and rotating the workpieces in a same attitude as that in which the workpieces are conveyed along said first and second conveyor lines;
- a transfer apparatus for transferring the workpieces from said first conveyor line through said machining apparatus to said second conveyor line while maintaining the workpieces in the same attitude, said transfer apparatus comprising a first transfer mechanism for transferring the workpieces from a pickup point on said first conveyor line to respective machining positions on said at least two machining apparatus, and a second transfer mechanism for transferring the machined workpieces from said machining positions to a delivery point on said second conveyor line, wherein said pickup and delivery points and said respective machining positions are disposed substantially colinearly along said transfer path, each of said first and second transfer mechanisms including holder means for holding the workpieces, wherein each said holder means comprises a pair of holder fingers movable toward and away from each other for supporting one of the workpieces;
- and
- each of said machining apparatus comprising at least one workpiece gripping mechanism for holding and rotating a workpiece in a horizontal attitude, and a cutting mechanism having at least one machining unit for simultaneously machining upper and lower surfaces of the workpiece which is being held and rotated by said workpiece gripping mechanism, said machining unit comprising a pair of cutting tools vertically spaced from each other and movable toward and away from each other, and said workpiece gripping mechanism comprising a vertically extending spindle and a chuck unit disposed upwardly of said spindle for gripping said workpiece.
