INDEXING ROTARY TABLES1. General information Variants / Number of stations Tab. 1 For the number of stations marked with (*), each complete cycle is achieved in 180° of the cam rotation It is possible to realise IR tables with different number of stations on request. Installation: - Position on face A. Clamp by 6 screw for IR1601 and 10 screws for IR1801 and 2001. Motion input: - Direct on cam shaft using conical lockers.

INDEXING ROTARY TABLES 4.Overall dimensions For standard holes on indexing plate see Pag. 6. An Idicator notch executed on the opposite front of the input shaft will be in the vertical position when the table is in the middle of cam dwell period. See Pag 8. The reducers are connected on the input shaft with conical lockers in substitution of feather key. 1) Housing without oil. 2) This dimensions are depending of the used motoreducer. 3) Dimensions depending of the rollers pitch circle.

INDEXING ROTARY TABLES7.Standard drilling scheme of indexing plate N.B. IR table is represented in the middle of a dwell in a station. On demand, can be supplied, INDEXING TABLE with special holes. COLOMBO FILIPPETTI SPA can also supply the motorization and overload protection systems for this rotary table. Other than the different possible solutions, depending on customer requirements and applications, a more defined and dimensional motorization can be used. Please contact our technical office for more informations.

INDEXING ROTARY TABLES 9.Anchoring system Indexing tables of this series are built with a centring diameter obtained in the lower side of the table aligned with the rotation axis of indexing plate. Three radial slots, also on the underside and perpendicular to the axis of rotation, enable the use of precision blocks (DIN 6322/B). By centring at least one block a very rigid torsional anchorage and a quick and accurate alignment of the table to the structure is obtained without any need of control equipment. BLOCKS TABLE

INDEXING ROTARY TABLES lO.Assembly of control cam for microswitches The applications for INDEXING TABLES frequently require a cam-limit switch unit to interrupt the motor drive at each cycle. The stop can have the function of extending the rest period of the cycle and/or of reversing the sense of rotation of the motor and consequently of the INDEXING TABLE and in which case will operate as a rocker unit. Limit switch cams are available in three standard shapes, each suitable for a particular type of limit switch as follows: On INDEXING TABLES. an "indicator notch" executed on both exposed...

INDEXING ROTARY TABLES 11.FC and FCR Micro Groups This simple micro groups permit identification only of the fact that the cam is in a certain position. If this position be the dwell period, the IR table must be in any one of perhaps several stations. It is sometimes necessary to know which particular station e.g. tables where oscillation between stations is required which is achieved by motor reversal. For machine start-up and for prevention of possible over-run, extra positional information is needed. One may also need several separate control signals for processes which are to be...

INDEXING ROTARY TABLES 13. Lubrication The lubrication of IR 1601, IR 1801 and IR 2001 tables is by oil bath, only the rollers are lubricated by conveyance of lubricant. The recommended lubricant is ISO VG 320 mineral oil or similar. Lubrication frequency, unless leakage or external pollution have occurred, is as shown in Tab. 15 and depends on the temperature achieved by the oil under standard operating conditions. The thrust bearing of indexing plate must be lubricated by specific grease cups every 1600 hours of work with 8 cm3 of ISO XM 2 grease. Indexing tables are delivered with this...
