PURPOSE:To permit secore positioning at an indexing position and facilitate multidirectional work by carvic-coupling a supporting body and a main indexing shaft, and a rotary table and a supporting member fixed on the main indexing shaft respectively. CONSTITUTION:A main indexing shaft 15 is supported rotatably and in axially slidable way in a supporting body 11, and carivic-coupled by shur gears 20 and 21. An L-shaped supporting member 25 is fixed at the front of the main indexing shaft, and a rotary table 29 is supported onto the supporting member 25 rotatably and in axially slidable way, and carvic-coupled by srur gears 32 and 33. The main indexing shaft 15 and the rotary table 29 are axially slided respectively by hydraulic pressure, for mounting and demounting of the coupling. |
