Patent DE-3827889-C1 (DE)
IPC: B23B5/44
Filed: 1988-08-17
Granted: 1989-03-23
Abstract: The attachment for machine tools, in particular milling machines and lathes, for producing irregular or regular polygonal surfaces on workpieces consists of a cutter head (2) which is to be fastened positively and non-positively to the spindle (1) of the machine tool and is provided with a certain number of cutting edges (tools 3) at the same angular spacings. Furthermore, a universal-joint shaft (11) displaceable in its longitudinal direction is likewise fastened positively and non-positively to the spindle (1). The other end of the universal-joint shaft is connected to a rotatably mounted workpiece carrier (5) to be fastened to the machine table (4), a gear train (7 to 9) between universal-joint shaft and workpiece carrier providing for a certain transmission ratio. When the transmission ratio is 1:2, a two-cornered figure is produced when there is one cutting edge, a square is produced when there are two cutting edges, a hexagon is produced when there are three cutting edges, etc. A triangle is produced when the transmission ratio is 1:3 or 1:1.5 and there is one cutting edge. A pentagon is produced when the transmission ratio is 1:2.5 or 1:1.25 and there is one cutting edge. This series can likewise be continued. A machine tool can be easily reset by this attachment in order to produce, with due regard to the geometric relationships, polygonal workpieces having few spherical surfaces. <IMAGE>
Patent DE-3909224-C1 (DE)
Title: Thrust-boring slide for accommodating a conventional horizontal drilling implement
IPC: E21B7/20
Filed: 1989-03-21
Granted: 1990-08-16
Abstract: In the case of house drain connections to be constructed, difficulties in making the trench often occur as a result of the supply carriers crossing at right angles and traffic problems. It is thus necessary to find a separable and easy-to-transport thrust-boring system with which it is possible to lay media pipes underground at the correct inclination from basement rooms without the abutment present during thrusting from the trench. The thrust-boring slide enables conventional thrust-boring units (5) to be accommodated. As a result of the guide sections (4) adjustable in inclination, exact orientation of the boring axis is possible. The thrusting forces are passed into the base frame (1) via the standing struts (3) and the bearings (13) and (14) and are passed from there via the anchorages (12) into the adjacent soil or into the head wall. An abutment can thereby be dispensed with. The above-mentioned system is suitable for laying media pipes underground at the correct inclination from basement rooms with the use of conventional thrust-boring units. The complete separability also guarantees transport through narrow basement exits and rooms. <IMAGE>
