Method and apparatus for delivering workpieces to and from a machine table
An apparatus and a method for delivering a workpiece to and from a machine table. The apparatus includes a rotatable plate and a pallet. The workpiece is detachably mountable to the pallet. The rotatable plate is movable with respect to the pallet. The pallet is movable along a pallet carriage. A screw is movably mounted within the screw housing and the screw housing is connected to the pallet. A driver is attached to the screw and moves the screw within the screw housing and the driver operates to engage the screw and move the pallet in a linear direction to and from the machine table.
1. An apparatus for delivering a workpiece to and from a machine table, the apparatus comprising:
a rotatable plate, a pallet, the workpiece detachably mountable to the pallet, the rotatable plate movable with respect to the pallet, a pallet carriage, the pallet movable along the pallet carriage, a screw housing, a screw movably mounted within the screw housing, the screw housing connected to the pallet, a driver attached to the screw and moving the screw within the screw housing, the driver operating to engage the screw and move the pallet in a linear direction to the machine table, and the pallet can move in a clockwise or a counterclockwise direction with respect to the rotatable plate.
2. The apparatus according to claim 1 , wherein the screw housing is connected to the pallet by a pin connected to the screw housing and the pin is removably engageable with the pallet to move the pallet to and from the machine table.
3. The apparatus according to claim 1 , wherein the rotatable plate houses a plurality of the pallets.
4. The apparatus according to claim 1 , wherein a movable bearing is attached to the pallet carriage and the movable bearing contacts a surface of the pallet.
5. The apparatus according to claim 1 , wherein the driver is a servo motor that moves the screw housing in the linear direction of the pallet to and from the machine table.
6. The apparatus according to claim 1 , wherein the driver is operated to move the pallet in the linear direction to and from the machine table.
7. The apparatus according to claim 1 , wherein a movable bearing is mounted between an outer surface of the rotatable plate and an underside surface of the pallet.
8. The apparatus according to claim 1 , wherein the screw, the screw housing and the driver are positioned outside of an exterior of the rotatable plate.
9. An apparatus for delivering a workpiece to a machine table, the apparatus comprising:
a rotatable plate, a pallet, the workpiece connected to the pallet, the rotatable plate movable with respect to the pallet, a screw housing, a screw movably mounted within the screw housing, the screw housing connected to the pallet, a driver attached to the screw and moving the screw within the screw housing and operating and engaging the screw and moving the pallet in a linear direction to the machine table, and the pallet can move in a clockwise or a counterclockwise direction with respect to the rotatable plate.
10. The apparatus according to claim 9 , wherein the screw housing is connected to the pallet by a pin connected to the screw housing and the pin is engaging with the pallet to move the pallet to and from the machine table.
11. The apparatus according to claim 9 , wherein a movable bearing is mounted between an outer surface of the rotatable plate and an underside surface of the pallet.
12. The apparatus according to claim 9 , wherein the screw, the screw housing and the driver are positioned outside of an exterior of the rotatable plate.
