Machine for drilling dowel holes from below has workpieces fitted in correct position from above on support surface on which tie rods are fixed which support slides on which guide rods are fixed to pass through clamping frame

摘要

The machine comprises a housing (1) with a support surface (2) on which the tie rods (3) are fixed which support the slides (4) on which the guide rods (5) are fixed which pass through the clamping frame (6). A through opening in the clamping frame clamps a commercially available drilling machine bit (10). The guide rods can be mounted directly underneath the support surface (2). The housing can be stood on two skids (17) which have inside a recess for the motor (8). The tension frame with motor and drill is forced up into the workpiece by leverage restricted at the top.
