Abstract
To locate a workpiece on the table of a drill press, the workpiece locator includes a shaft and a slide. The shaft is adapted to be mounted to the drill press spindle by a chuck and the slide is movably mounted to be adjusted in position perpendicular to the longitudinal axis of the shaft by a predetermined amount, which corresponds to the distance between the hole that is to be drilled and one side of the workpiece. A second side of the workpiece is located by measuring from a center line on the slide.
Claims25
A method of positioning a workpiece with respect to the direction of motion of a tool mounted to a drive means for performing work on the workpiece, comprising the steps of:
- extending an object a distance from a fixed location aligned with the direction of motion of the tool, which distance is equal to the distance from the location work is to be performed on the workpiece to a first side of the workpiece;
- indicating on a support means for the workpiece the location at the end of said object after it has been extended by the distance to one side of the workpiece, whereby one side of the workpiece is located with respect to the support means for work by said tool;
- measuring on said support means another dimension related to the distance from the location work is to be performed on the workpiece to a second side of the workpiece;
- and
- indicating the location of the second side of the workpiece at the end of said second measurement.
Apparatus for positioning a workpiece with respect to a tool held by a tool holder, which tool holder is adapted to move the tool along a path toward and away from the workpiece, comprising:
- a workpiece positioning body means;
- means for attaching said workpiece positioning body means to said tool holder;
- movable means movably attached to said workpiece positioning body means for indicating the position of side of said workpiece;
- means for extending said movable means a selected distance up to a predetermined maximum distance;
- and
- center line means on said workpiece positioning body means for indicating the center of said tool holder, whereby said movable means may be located in accordance with the dimension from the location where work is to be done by said tool on said workpiece and a side of the workpiece for indicating on a support member the location of one side of the workpiece.
