Abstract
An automatic machining system having one or more pallets each mounted with respect to a moveable bed, for transporting one or more workpieces to and/or from an automated machine tool, for machining each workpiece. According to this invention, a driver shaft and a driven shaft can be longitudinally aligned with respect to each other, so that there is no need for a gear system and/or a transmission device, for transferring power from a driver shaft to the driven shaft.
Claims16
In an automatic machining system having a pallet mounted with respect to a bed moveable with respect to an automated machine tool, wherein the pallet transports a workpiece to or from the automated machine tool for machining the workpiece, the improvement comprising:
- a carriage movably mounted with respect to a first drive shaft, a driver moving a second drive shaft, and the first drive shaft and the second drive shaft longitudinally aligned and coupled with respect to each other, wherein a coupling directly connects the first drive shaft with respect to the second drive shaft, the coupling including a first coupling part receiving the first drive shaft, a second coupling part receiving the second drive shaft, and the first coupling part mechanically connected to the second coupling part.
In an automatic machining system having a pallet moveable with respect to an automated machine tool, wherein the pallet transports a workpiece with respect to the automated machine tool, the improvement comprising:
- a carriage movably mounted with respect to a first drive shaft, a driver moving a second drive shaft, and a first center axis of the first drive shaft longitudinally aligned with a second center axis of the second drive shaft, and a coupling directly connecting the first drive shaft to the second drive shaft, the coupling first coupling part receiving the first drive shaft, a second coupling part receiving the second drive shaft and the first coupling part mechanically connected to the second coupling part.
In an automatic machining system having a pallet attachable to a bed moveable with respect to an automated machine tool, wherein the pallet transports a workpiece to or from the automated machine tool, the improvement comprising:
- a first drive shaft moveable with respect to the pallet, a driver moving a second drive shaft, and the first drive shaft and the second drive shaft longitudinally aligned and directly coupled with respect to each other, wherein a coupling directly connects the first drive shaft with respect to the second drive shaft, the coupling including a first coupling part receiving the first drive shaft, a second coupling part receiving the second drive shaft and the first coupling part mechanically connected to the second coupling part.
