Abstract
An apparatus for positioning a workpiece in a desired orientation for welding or the like during a manufacturing process is provided. The positioner has a generally vertical support column and a generally horizontal boom which is pivotally coupled to a top end of the support column. At a second end of the boom, the positioner has an arm member with a rotatable shaft extending therefrom upon which a workpiece may be mounted. The column is preferably mounted on a turntable such that the positioner may be rotated about a longitudinal axis of the column. In use, the positioner can move a workpiece up, down, left, right and to and fro to change the location of the workpiece. The orientation of the workpiece may also be changed by rotating the workpiece about a longitudinal axis of the shaft.
Claims25
An apparatus for positioning a workpiece in a desired orientation for welding, the apparatus comprising:
- a turntable having a top plate and a bottom plate;
- a support column having a top end and a bottom end, the bottom end of the column being connected to the top plate of the turntable;
- a boom having a first end and a second end, the boom being pivotally connected to the top end of the column;
- an arm member having a proximal end and a distal end, the proximal end of the arm member being pivotally connected to the second end of the boom;
- a boom cylinder coupling the column to the boom, whereby the boom cylinder pivots the boom about the column;
- an arm member cylinder coupling the boom to the arm member, whereby the arm member cylinder pivots the arm member about the boom;
- and
- a support shaft having a proximal end and a distal end, the shaft being coupled with the arm member adjacent the proximal end of the shaft and the distal end of the shaft being capable of receiving the workpiece.
An apparatus for manipulating the orientation of a workpiece comprising:
- a generally upright column having a top end and a bottom end;
- a boom having a first end, a second end, a top side and a bottom side, the first end being pivotally connected to the top end of the column;
- an arm member having a body with a plurality of arms extending therefrom, a proximal end and a distal end, the proximal end of the arm member being pivotally connected to the second end of the boom;
- a boom cylinder coupling the column to the boom, wherein the boom cylinder is coupled with the column on a side of the column adjacent the arm member and whereby the boom cylinder pivots the boom about the top end of the column;
- an arm member cylinder coupling the boom to the arm member, whereby the arm member cylinder pivots the arm member about the second end of the boom;
- a hydraulic power unit coupled with the cylinders for supplying power thereto;
- a support shaft having a proximal end and a distal end, the shaft being coupled with the arm member adjacent the proximal end of the shaft;
- and
- a workpiece mounting fixture coupled with the distal end of the shaft and being capable of receiving the workpiece.

- an arm member having a proximal end and a distal end, the proximal end of the arm member being pivotally connected to the second end of the boom;
- a boom cylinder coupling the column to the boom, wherein the boom cylinder is coupled with the column on a side of the column opposite the arm member and whereby the boom cylinder pivots the boom about the top end of the column;
- an arm member cylinder coupling the boom to the arm member, whereby the arm member cylinder pivots the arm member about the second end of the boom;
- a hydraulic power unit coupled with the cylinders for supplying power thereto;
