Index pin for fixing interlock of turntable of rotary table or rotary transfer machine, is guided in linear motion by ball or roller cage guide, where guide bushing of index pin is guided in load-bearing contact

摘要

The index pin (5) is guided in a linear motion by a ball or roller cage guide (13). Precision ground and hardened guide bushing (6) of the index pin is guided in a load-bearing contact and in a front plate (4) by a frictional shifting process of the ball or roller. The ball or roller cage guide and the guide bushing are protected by a locking ring (12) for limiting the travel.
