Munich, Munich District, Germany |
Application in Switzerland, 17 Sept., 1958.
Abstract:
It is the object of the invention to provide inspection and gauging equipment of the said kind with a fitting which will permit the equipment to be adjusted and clamped with a minimum of effort and trouble either in fixed position or for rotation. Another object of the invention is the provision of means which in the case of rotatable equipment will prevent inaccuracies in alignment between individual transmission elements from affecting the true central rotation of the gauging element and from causing dislocations and jamming. The invention also contemplates the provision of means which will permit the gauging element to be affixed and rotated with the help of a single control element so that the operations required for setting up and using the equipment will be reduced to a few simple manipulations. The invention solves the objects set forth above by embodying the fitting for the reception of optionally attachable alternative measuring and gauging elements in a rotatably mounted adapter associated with means for rotating and means for clamping the same in any desired position. According to another feature of the invention the means which establish the connection between the adapter and the cooperating transmission means for imparting rotation thereto are arranged to permit relative radial displacement. To fix the adapter in a given position it is preferred to make use of a member which is fixed to the rotatable adapter, particularly in the form of a fiat ring which can be pressed against a cooperating stationary surface by means of a clamping screw.
Claim:
A holder adapted to releasably receive any one of various measuring and gauging optional attachments, said holder comprising a detachable head, an adapter sleeve mounted in said head so as to be freely rotatable but not displaceable in an axial direction, said adapter sleeve having a central bore including an outwardly tapering outer end portion, a gear ring mounted within said head for rotation independent of the rotation of said adapter sleeve and concentric therewith, manually operable means operatively connected to said gear ring for rotating said gear ring, a cylindrical bushing disposed partly within said gear ring and adapter sleeve, gear teeth means for rotating said bushing in response to rotation of said gear ring, a cone-shaped tubular attachment holder having an outer frusto-conical surface releasably wedged in said tapering bore end portion of said adapter sleeve, thread means for connecting adjacent ends of said holder and bushing and operative to draw said holder into said adapter sleeve in response to operation of said manually operable means, said holder being wedged in said adapter sleeve for rotation therewith in response to subsequent operation of said manually operable means. |

Munich, Munich District, Germany |
Prior application in Germany, 19 Nov., 1959.
Abstract:
This invention relates to a machine tool, and particularly to a milling machine having a spindle head which is displaceable in the direction of the axis of the tool spindle (or the axes of the tool spindles, if more than one) relative to the gear case, and in which at least one tool spindle is displaceable in the same direction relatively to to the spindle head. Machine tools of this construction have the advantage of a large working range of the tool, because after exhausting the displaceability of the spindle head relative to the gear case on which it slides, the tool spindle itself can then be further displaced in the same direction, being pushed axially out of the spindle head. Such a machine tool can also be used as a boring machine, due to the possibility of advancing the tool in the direction of the axis of the tool spindle. Prior machines of this character have not been able to take full advantage of these possibilities, however, because for precision work a mechanically driven feed is necessary, and because in the prior machines of this general character a mechanically driven feed has been available either only for the feeding of the spindle head, or only for the feeding of the tool spindle, while the other one of these feeding motions has had to be performed manually.
Claim:
A machine tool comprising a gear case, a spindle head mounted on said gear case, a plurality of tool spindles rotatably mounted in said spindle head with their axes parallel to each other, at least one of the tool spindles being mounted for axial feeding displacement relative to the spindle head, said spindle head being mounted for feeding displacement relative to said gear case in a direction parallel to the axes of said tool spindles, characterized by a first feed screw operatively connected to said spindle head to feed said spindle head relative to said gear case when said first feed screw is moved longitudinally relative to said gear case, spindle feed means including a second feed screw and a nut threadedly engaging said second feed screw and held against rotation in said spindle head to travel longitudinally on said second feed screw when said second feed screw is turned, an operative connection between said nut and said displaceable tool spindle to feed said displaceable tool spindle axially from axial movement of said nut, an operative connection between said first feed screw and said second feed screw to turn the latter from rotation of the former, a second nut mounted in said gear case for rotation without axial movement, said second nut being threaded on said first feed screw, power operated means for turning said second nut, and shiftable clutch means movable between two positions in one of which said first feed screw is held against rotation and in the other of which said first feed screw is coupled to said second nut to turn therewith, so that when said first feed screw is held against rotation the rotation of said second nut will cause longitudinal movement of said first feed screw to feed said spindle head relative to said gear case, and so that when said first feed screw is coupled to turn~ with said second nut, rotation of said second nut will not cause longitudinal movement of said first feed screw but will cause joint rotation of said first feed screw and said second feed screw, thereby feeding said displaceable tool spindle. |

Claims priority, application in Germany, 27 Feb., 1962.
Abstract:
The minimum design requirement that should be placed on any universal milling machine or the like is that it should be able to carry out all jobs in the horizontal and vertical planes. In order to satisfy this basic requirement, machines in the prior art are equipped either with a tool spindle capable of being swiveled between the horizontal and vertical planes, or with two separate tool spindles, namely a fixed horizontal spindle and a fixed vertical spindle. Now if the cost outlay necessary for constructing machines with the three separate and different types of spindles, namely the fixed horizontal, fixed vertical and swiveled spindle, is measured and compared with the precision of the work produced by operators with each type machine and with the work which can be produced with each machine, in a given time, the fixed horizontal plane machine is found to be the best value machine, that is, the lowest in cost for the quality and quantity standard of work which can be produced with such machines.
Claim:
A universal machine tool of the type having a clamping table and a tool means which are movable relative to each other in three coordinate directions, the improvement comprising, in combination, a fixed horizontal tool axis means connected to said tool means, a clamping surface adapted to receive a workpiece carried by said clamping table, said clamping surface disposed for swiveling around a first pivot axis means on said clamping table disposed at substantially 45° to clamping surface, and said clamping surface disposed for rotation around a second pivot axis means vertically disposed on said clamping table and at substantially 45° said first pivot axis means for selectively positioning all sides of a workpiece clamped on said clamping surface adjacent said fixed horizontal tool axis means for work thereon, thereby providing a more stable fixed horizontal tool axis means. |

Tracer Milling Machine
|
Johann Müller |
Munich, Munich District, Germany |
Claims priority application in Germany, 21 Nov., 1962.
Abstract:
Designs for tracer milling machines on which both roughing operations and subsequent finishing operations are to be performed are well known in the prior art. Usually in machines of this type the same tool is used for both the roughing and finishing operations. The finishing device is normally freely movable in three directions and directly guided by hand, and is connected to the machine column by means of a clamping arm. When roughing operations are performed by the finishing device feed and depth-of-cut motions -are assigned to the work piece table. However, experience has shown that this design is not sufficiently rugged for heavy roughing operations, because the finishing device in itself must be built relatively light in order for it to be guided directly by hand during the finishing portion of the operation. For this reason, it has been proposed in the art to provide one tool each for 'roughing and finishing, each with its own feeler or stylus. Both tools, which in this case are better adapted for their respective uses, are brought into operating position alternately, usually by shifting them along horizontal guides on the machine column. How- ever, this arrangement usually results in a large cumbersome machine and it is often 'times difficult to obtain the ruggedness necessary for exact machine operation on large work pieces. It is therefore one of the objects of the invention to provide a tracer milling machine which is exceptionally rugged in construction and provides a movable tool head .designed to more favorably counteract bending moments than the tool heads of prior art tracer milling machines.
Claim:
A tracer milling machine of the type having a table for a work piece and a model adapted for movement in three directions comprising: a pair of machine columns disposed in spaced relation, a tool head connected for rotation about a horizontal axis between said machine columns, said tool head carrying faces disposed parallel to the axis of rotation, a roughing tool, surface means carrying said roughing tool connected to one of said faces, a first feeler connected to said roughing tool, a finishing device having a tool and second feeler connected to another of said faces, whereby said roughing tool and finishing device are alternately brought into working position above the table by rotation of said tool head. |

Abstract:
This invention relates broadly to milling machines having console type table carriers and more particularly to a universal milling machine having a plurality of tool spindles. One of the objects of the present invention is to provide a construction of a relatively small console type milling machine which is capable of carrying out heavy milling jobs. Another object of the invention is to provide a construction of milling machine having a console-like table carrier, having improved spindle head stability and increased stability for the guidance of the table in all three coordinate directions. Still another object of the invention is to provide a construction of milling machine having a plurality of tool spindles to permit machining of work pieces of different sizes. A further object of the invention is to provide a construction of milling machine wherein a plurality of tool spindles can be pivoted from one plane to another to provide a universal milling machine for machining work pieces from different directions while maintaining the dimensions of the machine at a minimum. Still a further object of the invention is to provide a construction of milling machine having increased accuracy of the table console guidance and enlargement of the longitudinal and transverse guidance of the table.
Claim:
A milling machine comprising, a machine stand, a chucking table adapted to receive a work piece and movable in three coordinate directions mounted on said machine stand, a swivel axis through said machine stand above said chucking table parallel to the longitudinal movement of said table, a spindle head connected to swivel about said axis, and a pair of parallel tool spindles on said spindle head having axes in a vertical plane parallel to the transverse movement of said table. |

Neukeferloh, Munich District, Germany |
Claims priority in Germany, 26 Mar., 1964.
Abstract:
This invention relates to a copying milling machine, that is, a machine for reproducing on a work piece the configuration or shape determined by a pattern or template. An object is the provision of an improved copying milling machine in which the roughing operation on the work is performed by power feed means controlled by a tracer which engages the pattern or template, and in which the power feed parts can be quickly disconnected or made inoperative to permit the final finishing operation to be performed by hand in a most convenient and easy manner. Still another object is the provision of a machine so designed as to give improved rigidity and sturdiness as compared with prior machines, and at the same time an improved layout or arrangement of work table and pattern or template table with relation to each other, to enable the work and the template to be located in position more convenient to each other and more convenient to the location of the operator. A further object is the provision of a simple, sturdy, and compact copying milling machine so designed as to accommodate an increased size of work piece as compared with many prior machines, and one in which the milling operation is performed at a convenient location with relation to the eyes of the operator, notwithstanding that different work pieces operated upon at different times may have considerably different vertical dimensions. A still further object is the provision of a copying milling machine so designed and constructed that transmission of vibrations from the work piece and the milling spindle to the tracer is reduced to a minimum.
Claim:
A copying milling machine comprising an upstanding main column, an upstanding auxiliary column spaced from the main column, a work table in the space between said two columns, said table being mounted for vertical movement and also longitudinal horizontal movement, a substantially horizontal crosshead resting on and bridging the space between said column, a vertical milling spindle head supported from said crosshead and displaceable horizontally thereon in a direction transverse with respect to the direction of longitudinal movement of said work table, and a template table spaced laterally from said work table and located at least partly on the opposite side of said auxiliary column from said work table, said template table being operatively connected to said work table to move therewith during both the vertical movements and the longitudinal horizontal movements of said work table. |

Boring Head for Machine Tools
|
Johann Müller |
Unterhaching, Munich District, Germany |
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. |
