Drill pedestal adjuster for deep drilling machine - has releasable clutches between individual pedestals and toll spindle box, with electric drive in each pedestal

摘要

The adjuster has the drill supports (11,21,31) coupled together and to the machine tool spindle casing (12) via releasable clutches. Each support has its own electrical device for the clutch release. These electrical devices are controlled by a common unit. When the spindle casing returns, the control unit switches on the release device of the last support at that moment, when the spindle casing passes a given point on the bed (10) holding the supports.
