ABSTRACT:
In an indexing system for a member such as a turret head of a lathe, in which the member after undergoing an indexing movement is locked by a locking bolt thrust by spring force into a bolt hole in a plate coaxially fixed to the member, a hydraulic cylinder is used to exert a great force for holding the locking bolt positively and unmovably in each bolt hole against any reactive counter force from the side of the member due to a great load. The hydraulic cylinder is controllably actuated by a single hydraulic system containing also a hydraulic motor for driving the member in its indexing movement and a solenoid valve.
