Abstract
A reciprocating table assembly includes a frame, a table, and a bearing assembly for rotatably mounting the table to the frame. A cylinder assembly rotates the table at a pivot point by extending and retracting a piston rod from the cylinder. Three sensors sense which position the table is in its rotational path and signal the piston rod to either extend or contract at the appropriate time.
Claims11
A reciprocating table assembly comprising:
- a frame;
- a table;
- a bearing assembly rotatably mounting said table to said frame for rotation about a table axis;
- a cylinder assembly comprising a cylinder, a piston, and a rod carried by said piston, said piston and rod being movable within said cylinder between extended and retracted positions;
- said cylinder being connected to said frame;
- said rod being pivotally connected to said table at a pivot point spaced from said table axis;
- said table being rotatable from a first position wherein said rod is in said extended position to an over center position wherein said rod is in said retracted position to a second position wherein said rod is again in said extended position;
- first, second, and over center sensors for sensing when said table is in said first position, said second position, and said over center position;
- and
- control means connected to said cylinder assembly and to said first, second and over center sensors for moving said rod from said extended position to said retracted position to move said table from said first position to said over center positions, and for moving said rod from said retracted position to said extended position to move said table from said over center position to said second position.
