ABSTRACT:
An improved clamping mechanism for clamping a workpiece as it is moved through an automatic drilling machine. A workpiece, such as a wide flange beam, is supported and conveyed on a plurality of lower rollers, and a group of upper rollers are moved into clamping engagement with the upper surface of the beam. The ends of each upper roller are journalled within slides which are mounted for vertical movement on the frame of the machine, and a hydraulic cylinder unit is connected to each slide so that operation of the cylinder unit will move the upper roller in a direction toward and away from the beam supported on the lower rollers. A shaft extends parallel to the upper roller and innerconnects the slides and gears are mounted on opposite ends of the shaft and are engaged with racks mounted on the frame. Movement of the slides through operation of the cylinder units will correspondingly move the gears relative to the racks to maintain both ends of the upper roll in precise horizontal alignment with the lower rolls.
