Abstract
A machine for creating holes in a structural angle, including parallel plates including (1) an earth plate perpendicular to an axial direction and positionable at a fixed position relative to the structural angle, (2) a top plate mounting a workpiece tool, (3) a bottom plate spaced a fixed distance from the top plate, both plates being supported for axial movement relative to the earth plate, and (4) a support plate between the earth plate and the top plate and supported for axial movement relative to the earth plate. The support plate is biased toward the top plate and away from the earth plate. A first stop limits movement of the bottom plate toward the earth plate and a second stop limits movement of the support plate away from the earth plate. A drive selectively moves the support and bottom plates axially away from each other.
Claims29
A machine for pressing a workpiece tool against a workpiece in the direction of a first axis, said machine comprising:
- an earth plate oriented substantially perpendicular to the first axis and adapted to be selectively positioned at a fixed position relative to said workpiece when pressing a tool toward the workpiece;
- a top plate oriented substantially parallel to said earth plate and adapted to mount a workpiece tool thereto;
- a bottom plate oriented substantially parallel to said earth plate and spaced a fixed distance in the direction of the first axis from the top plate, said top and bottom plates supported for movement relative to the earth plate in the direction of the first axis;
- a support plate between the earth plate and the top plate and supported for movement relative to the earth plate in the direction of the first axis, said support plate being adapted to mount a support block thereto;
- means for biasing said support plate away from said earth plate and toward said top plate;
- a first stop limiting movement of said bottom plate toward said earth plate;
- a second stop limiting movement of said support plate away from said earth plate;
- and
- a drive adapted to selectively move said support and bottom plates away from each other in the direction of the first axis.
A machine for pressing a workpiece tool against a workpiece in the direction of a first axis, said machine comprising:
- an earth plate adapted to be selectively positioned at a fixed position relative to said workpiece when the tool is pressed toward the workpiece;
- top and bottom plates spaced apart a fixed distance in the direction of the first axis and supported for movement relative to the earth plate in the direction of the first axis when said earth plate is positioned at the fixed position, said top plate being adapted to mount a tool;
- a support plate between the earth plate and the top plate and supported for movement relative to the earth plate in the direction of the first axis when said earth plate is positioned at the fixed position, said support plate being adapted to mount a support block thereto;
- means for biasing said support plate away from said earth plate and toward said top plate in the direction of the first axis;
- a first stop limiting movement of said bottom plate toward said earth plate;
- a second stop limiting movement of said support plate away from said earth plate;
- and
- a drive adapted to selectively move said support plate and said bottom plate in the direction of the first axis relative to each other;
- whereby
- when said drive moves said support plate and said bottom plate toward each other with said bottom plate engaging said first stop, said support plate is moved toward said earth plate,
- when said drive moves said support plate and said bottom plate away from each other, said support plate is first moved to its limit away from said earth plate and then said bottom plate is moved away from said earth plate to move said top plate toward said support plate.
