Rotary indexing tables with planetary units are "the specialists" for multiple side machining in rotary cycle machines. There are as many designs as there are workpieces and their machining. Fibro, a specialist in rotary indexing tables, has available all the elements from its series production as well as the experience and equipment to meet even the most difficult requirements.
The carrier rotary indexing table as basis is a FIBROTAKT® with flat toothing. This gives the table permanently the precise pitch and a very good rigidity.
The indexing plate is either lifting or not lifting. The lifting design (type 11.13 ...) is used for lower mass moments of inertia and therefore for smaller indexing plates. The switching movement is carried out by a hydraulically operated rack and pinion.
The non-lifting version (type 10.36 ...) is used for high moments of inertia and short switching times. Particularly advantageous is the Störkonturfreie housing with bottom drive. The switching movement is performed by a servo motor with bevel-helical gearbox via a pinion shaft to a large drive gear
Unlocking and locking the face gear is hydraulic.
With the designs described above, the planet units can be positioned with either vertical or horizontal axes.
As all other indexing tables with planetary units, this type also serves as central unit on rotary transfer machines. The special feature is that the enabled section of the indexing tables is mounted circularly and at an even divisional pitch on a stationary base. The carrier indexing table transports the planetary units, which are designed here exclusively as workpiece carriers (pallets), to the rotary indexing tables, where they are positively secured and clamped. The advantages of the system are: fixed assignment of the rotary indexing table to the processing units in each individual station; complete exchange of the workpiece carriers allowing fast changeover.
The application of transfer indexing tables with planetary units is extended by additional designs and variants
