Tooling arm
A tooling arm includes a housing, a drive system, a lead screw and nut assembly, and a scoop assembly. The lead screw and nut assembly is operably connected to the drive system such that rotation of the nut drives the lead screw upwardly and downwardly relative to the housing. The scoop assembly is operably connected to the lead screw. The scoop assembly has an open position and a closed position and movement of the lead screw downwardly responsively moves the scoop assembly from the open position to the closed position.
1. A tooling arm comprising:
a housing;
a drive system;
a lead screw and nut assembly having a lead screw operably connected to the drive system such that rotation of a nut drives the lead screw upwardly and downwardly relative to the housing;
a scoop assembly having a pair of scoops, a pair of links and a shuttle, with each scoop being pivotally attached to the shuttle, each link being pivotally attached at one end thereof to a bracket and the other end thereof to one of the pair of scoops and wherein the scoop assembly acts as a four bar link mechanism; and
wherein the scoop assembly is connected to the lead screw, and the scoop assembly has an open position and a closed position and movement of the lead screw downwardly responsively moves the scoop assembly from the open position to the closed position.
2. The tooling arm as claimed in claim 1 wherein the bracket is attached to a lower end of the lead screw.
3. The tooling arm as claimed in claim 2 wherein the shuttle includes a stopper which engages a block connected to the housing.
4. The tooling arm as claimed in claim 3 wherein the drive system includes a motor and gear head assembly.
5. The tooling arm as claimed in claim 4 wherein the housing includes an upper mounting plate and the motor and gear head assembly is attached thereto.
6. The tooling arm as claimed in claim 1 wherein the lead screw and nut assembly includes a guide tube having a slot therein and wherein the lead screw includes a screw pin extending through the lead screw and its motioning is limited by the slot.
7. The tooling arm as claimed in claim 1 wherein the drive system includes a motor and gear head assembly.
8. The tooling arm as claimed in claim 7 wherein the housing includes an upper mounting plate and the motor and gear head assembly is attached thereto.
9. The tooling arm as claimed in claim 8 wherein the lead screw and nut assembly includes a guide tube having a slot therein and wherein the lead screw includes a screw pin extending through the lead screw and its motioning is limited by the slot.
10. The tooling arm as claimed in claim 1 wherein the lead screw is rotatably connected to the nut which is driven by a pair of meshing spur gears which is driven by a motor.
11. The tooling arm as claimed in claim 1 wherein the tooling arm is operably connected to a mobile robot.
12. A tooling arm comprising:
a housing;
a drive system;
a lead screw and nut assembly having a lead screw and a guide tube, the lead screw being operably connected to the drive system and having a screw pin extending through the lead screw, the guide tube having a slot therein, whereby the lead screw motioning is limited by the slot such that rotation of a nut drives the lead screw upwardly and downwardly relative to the housing; and
a scoop assembly connected to the lead screw, the scoop assembly having an open position and a closed position and movement of the lead screw downwardly responsively moves the scoop assembly from the open position to the closed position.
13. The tooling arm as claimed in claim 12 wherein the drive system includes a motor and gear head assembly.
14. The tooling arm as claimed in claim 13 wherein the housing includes an upper mounting plate and the motor and gear head assembly is attached thereto.
15. The tooling arm as claimed in claim 12 wherein the lead screw is rotatably connected to the nut which is driven by a pair of meshing spur gears which is driven by a motor.
16. The tooling arm as claimed in claim 12 wherein the tooling arm is operably connected to a mobile robot.
