Abstract:

A manually positioned computer controlled drilling machine (10) is disclosed for drilling a hole (12) through a surface (14). The machine includes a base (16) which is supported on a counterbalanced suspension so that an operator can manually move and shift the machine on the surface to be drilled. Automatic adjustable legs (20-26) are biased outwardly from the base by low pressure air cylinders which allows the operator to tilt and move the base (16) relative to the surface (14). This allows the operator to position the drill bit (18) over the position where the hole is to be drilled and orient the drill bit perpendicular to the surface. Caliper brakes (38) are then activated to lock the legs in place. A number of suction cup assemblies (42-52) are then sequentially moved outward into contact with the surface. A suction foot (56) on each of the suction cup assemblies is adhered to the surface by a vacuum.
