Slide Guide for Machine Tools

Munich, Germany |
Germany application 14 May 1938.
Abstract:
This invention deals with guiding means for slides or similar moving parts of machine tools and similar machines. An object of the invention is the provision of an improved guide arrangement for such slides v or similar parts. Another object is the provision of guiding means which is capable of bearing relatively heavy loads without undue friction, so that the slide or similar part supported by this guiding means is movable relatively easily and freely, notwithstanding heavy load conditions.
Claim:
Guiding and supporting means for accurately guiding and supporting heavy relatively movable parts of machine tools and the like, said guiding and supporting means including means forming a V-shaped groove on one of said parts, means forming a V-shaped groove on the other of said parts, said grooves being faced toward each other and extending longitudinally in the direction in which the two parts are to be moved relatively to each other, and a series of a relatively large number of rollers spaced relatively closely to each other with the clear distance between adjacent rollers substantially less than the diameter of each roller, said rollers being placed between said two grooves and extending into both of them, said rollers having axial length slightly less than their diameters and certain of said rollers having their axes lying in a common plane at a substantial angle to the common plane of the axes of certain other rollers. |

Boring Head for Machine Tools

Claim priority, application in Austria, 31 Aug., 1967.
Abstract:
A boring head for application to a machine tool such as a milling machine, has a rotatable flange on which a tool holder is displaceable in a diametrical direction perpendicular to the axis of rotation of the flange. To enable precise reading of the extent to which the tool holder is displaced radially from a given position, the displaceable tool holder is provided with a scale parallel to the direction of displacement, read by means of a magnifying glass also displaceable for adjustment in the same direction, the magnifying glass being mounted on a bracket arm swingable on a pivot on a stationary part of the housing containing the bearings for the rotatable flange. The pivot on which the magnifying lens swings is at right angle to the axis of rotation of the flange, and the parts are so arranged that when the magnifying lens is not in use for reading the displacement scale, it may be swung up to a position out of the way of the coolant and the chips. Background of the invention In the machine tool art, it is known to have a boring head which includes a rotatable flange on which a tool holder is mounted for displacement in a direction radially, or diametrically with respect to the axis of rotation of the flange, so that the tool may perform facing or boring operations concentrically around the axis of rotation of the flange, at a distance therefrom which is variable by varying the extent of radial displacement of the tool holder. It is also known to provide the displaceable tool holder with a scale for reading the extent of displacement, the index of the scale being developed at times as a vernier. An example of this is the construction disclosed in Swiss Pat. 232,960, granted in 1944. The accuracy obtainable by such a construction is, however, frequently not sufficient.
Claim:
A boring head comprising a nonrotating housing, a rotatable member rotatable with respect to said housing about ani axis of rotation, a tool holder mounted on said rotatable member for displacement thereon in a radial direction with respect to said axis of rotation, a graduated scale mounted on said tool holder and extending in a direction parallel to said direction of displacement of said tool holder, and a magnifying lens mounted on said housing effective position for reading said scale to an ineffective for swinging movement relative thereto from an 5position substantially removed from said scale. |
