A fixture for the adjustable mounting of board-like furniture parts on the work table of a drilling machine. Underneath the drilling head of the machine, backstop rails which project slightly above the supporting surface of the work table are disposed in alignment with one another and longitudinally displaceably at equal distances on opposite sides of a longitudinal central plane. The ends of a threaded spindle are threaded into the ends of the backstop rails adjacent the drilling head, the threaded spindle being provided on each half with contrary threads of equal pitch. The threaded spindle is mounted rotatably but in a longitudinally undisplaceable manner on the work table. Cursors are longitudinally displaceable on the upper sides of the backstop rails and can be fixed at given uniform distances on the associated backstop rail, and each bears a stop which is biased to a position projecting toward the surface of the work table, and which can be retracted into the cursor against the bias. |
