Abstract
A drilling machine for a mobile drilling appliance which includes a housing which is adapted to travel along a jobber, a drive motor mounted on said housing, a pinion operatively connected to said drive motor, a step-down gear rotatably engaging said pinion, a driving socket located in the vicinity of a side face of said housing that contains a central opening which is adapted to receive a driving shaft that in turn is adapted to be connected to a drilling tool, and a driving ring positioned in said driving socket and engageable with said step-down gear.
Claims8
A drilling machine for a mobile drilling appliance which comprises in combination
- (a) a housing (14, 16, 18) which is slidably mounted to a jobber (12),
- (b) a drive motor (22) mounted on a part of said housing,
- (c) a pinion (26) operatively connected to said drive motor (22),
- (d) a step-down gear (32) rotatably engaging said pinion (26), the diameter of said step-down gear (32) being large in comparison with the diameter of said pinion (26),
- (e) a driving socket (50) located in the vicinity of a side face of said housing (18), said socket (50) containing a central non-circular opening (52) receiving in an axially displaceable manner, a driving shaft (56) that in turn is connected to a drilling tool (60), and
- (f) a driving ring (54) positioned in said driving socket (50) around said opening (52) and engageable with said step-down gear (32), the diameter of said driving ring (54) being small in comparison with the diameter of the surface of said step-down gear (32) that engages said pinion (26).
