Feed mechanism for drilling machines
|
Albert M. Johnson |
Rockford, IL |
The innovation is a compact arrangement of spur gears that provide the necessary slow-speed high-torque drive needed for feeding a drill press. Previous mechanisms tended to rely on a worm-gear reduction which were prone to excessive wear in this application. |

Carlson, Pitzner, Hubbard & Wolfe - patent attorneys
The invention relates to machines for finishing elongated bores by a honing or lapping operation, and more particularly to control mechanism for such machines. In a honing or lapping operation a radially expansible cylindrical abrasive tool and a workpiece are relatively rotated and simultaneously relatively reciprocated axially of the bore in the workpiece, which is to be finished. During such rotation and reciprocation, the abrasive elements of the tool expand into operative engagement with the walls of the bore. The amount of material removed from the bore walls and thus its finished diameter is determined in part by the number of times the tool is traversed over the walls. It will be apparent, therefore, that when the tool is traversed only part way through the bore, more material will be removed from the walls adjacent the entering end than from the opposite end, with a corresponding increase in the diameter of the bore at such entering end. The primary object of the present invention is to provide improved control mechanism whereby the above principle may be utilized to advantage in generating tapered or stepped surfaces in bores initially machined to cylindrical contour. More specifically stated, an object of the invention is to provide control mechanism operative automatically to reduce the length of the tool stroke progressively by predetermined increments so as to generate a bore of gradually increasing diameter. Another object is to provide a control mechanism of the above general character which is readily adjustable to produce a wide range of surface finishes including, on one hand, a finish in which the stepped areas of the surface are so short measured axially of the bore as to afford a substantially uniform taper from one end of the bore to the other, or alternatively, a finish in which the stepped areas are relatively long and prominent. It is also an object of the invention to provide stroke control mechanism for honing machines which is simple in construction, efficient and dependable in operation and which can be applied to conventional honing machines to increase their utility without affecting their normal mode of operation. |
