Abstract
1,268,533. Indexing. VOITH GETRIEBE K.G. 11 Jume, 1969 [11 June, 1968], No. 29592/69. Heading B3B. An indexing unit for a machine tool comprises a turntable 1 on a bed 2, toothed rings 7, 8 mounted respectively on the table and bed which are engageable to locate the table 1 accurately and disengageable for indexing movement, the drive to the table 1 being coupled to a position transmitter 11 which emits a number of pulses for each division of relative rotation of the toothed rings 7, 8, whereby the drive motor 16 can be numerically controlled for any desired coarse indexing step, the drive to the table 1 including flexible coupling means which can be displaced when the final accurate positioning movement of the table is brought about by engagement of the toothed rings. As shown, the flexible coupling comprises a worm 15 which may be axially displaced against the action of springs 17, 18. During normal indexing drive the displacement of the springs 17, 18 is negligible. Axial movement of the ring 9 to disengage the toothed rings 7, 8 may be effected by fluid-pressure cylinders 13 and plungers 10 against the action of springs 14. The bearing surface 12 of the table 1 on the bed 2 may be formed as a hydrostatic bearing to facilitate indexing movement. In an alternative embodiment (Figs. 3, 4, not shown) resilient coupling members are located between spokes projecting from concentric annular members constituting a drive gear for the table.
