An apparatus for positioning and clamping workpieces in a processing station, comprising:
- (a) a processing station having a clamping device including alignment means for complimentarily engaging and aligning a workpiece to be processed in the processing station;
- (b) a workpiece pallet for transporting a workpiece to said processing station, said workpiece pallet including a workpiece carrier for carrying the workpiece during transport to said processing station with the workpiece displaceably placed on the workpiece carrier so as to provide sufficient play to the workpiece being carried to enable the workpiece to engage and be aligned by said alignment means at the processing station;
- (c) feed device means for conveying the pallet, workpiece carrier and workpiece to said processing station;
- and
- (d) means at said processing station for lifting the pallet with the workpiece thereon so as to press the workpiece against and align the workpiece with the alignment means and thereby clamp the workpiece between the pallet workpiece carrier and the alignment means, for processing the workpiece in the processing station.
A process for positioning and clamping workpieces in a processing station, comprising:
- (a) providing a processing station including alignment means for complimentarily engaging and aligning a workpiece to be processed in the processing station;
- (b) providing a workpiece pallet for transporting a workpiece to said processing station, said workpiece pallet including a workpiece carrier for carrying the workpiece during transport to said processing station;
- (c) displaceably placing a workpiece on the workpiece carrier so that the workpiece carrier provides sufficient play to the workpiece being carried to enable the workpiece to engage and be aligned by said alignment means at the processing station;
- (d) conveying the pallet, workpiece carrier and workpiece to said processing station;
- and
- (e) lifting the pallet with the workpiece thereon at said processing station so as to press the workpiece against and align the workpiece with the alignment means and thereby clamp the workpiece between the pallet workpiece carrier and the alignment means, for processing the workpiece in the processing station.
An apparatus for positioning and clamping a workpiece for processing at a processing station comprising:
- (a) a pallet for transporting the workpiece to the processing station and for carrying the workpiece with sufficient play to permit positioning and clamping at the processing station;
- (b) a workpiece holder at the processing station for engaging the workpiece,
- (c) means for pressing the pallet with the workpiece against the workpieces holder so that the workpiece holder engages and positions the workpiece and so that the workpiece is clamped in the desired position for processing between the pallet and the workpiece holder.
Method for positioning and clamping a workpiece for processing at a pressing station comprising the steps of
- (a) transferring the workpiece to the processing station on a pallet which holds the workpiece with sufficient play to permit positioning;
- (b) pressing the pallet and thereby the workpiece towards a workpiece holder at the processing station so that the workpiece is brought by the workpiece holder to the desired final position,
- (c) pressing the pallet further against the workpiece holder so that the workpiece is clamped between the pallet and the workpiece holder.
