Abstract
An automatic tapping machine for a tapping operation includes a movable truck; a lower frame rotatably mounted on the truck, an upper frame arranged always in parallel with the lower frame, and a pressure actuatable device for moving the upper frame towards, and away from the lower frame. A jig-supporting mechanism is adapted to hold a jig for use in the tapping operation, and a device is provided for supporting the jig-supporting mechanism above the frame and for actuating the jig-supporting mechanism as required in a tapping operation; the jig to be held in the jig-supporting mechanism has a diameter ranging from 40 mm to 100 mm.

An automatic tapping machine for a tapping operation comprising a movable truck, a lower frame rotatably mounted on said truck, an upper frame arranged always in parallel with said lower frame, pressure actuatable means for moving said upper frame towards and away from said lower frame, a jig supporting mechanism adapted to hold a jig for use in the tapping operation, and a means for supporting said jig supporting mechanism above said frame and for actuating said jig supporting mechanism as required in the tapping operation, said jig holdable in said jig supporting mechanism having a diameter ranging from 40 to 100 mm.
An automatic tapping machine for tapping operation comprising a movable truck;
- a lower frame rotatably mounted on said truck;
- an upper frame arranged always in parallel with said lower frame;
- pressure actuatable means for moving said upper frame towards and away from said lower frame;
- a jig supporting arm mechanism including at least two arms which are made movable in the longitudinal direction relative to each other, one of said arms being pivotted to said upper frame while the other arm being adapted to hold at its leading end a jig for the tapping operation;
- and pressure actuatable means for vertically tilting said jig supporting arm mechanism at the pivot relative to said upper frame, each of said arms of said jig supporting arm mechanism having a pressure actuatable means provided for moveing the adjacent arm in its longitudinal direction.
