System for rapid automatic exchange of spindle tools machining, e.g., massive undercut freeform molds, includes spindle clamp and tool wrench

摘要

The drive spindle (3) working end carries guide recesses (6), used to lock it in a set angular position. Its shoulder rest and central spindle couple with the tool (7). Concentric with the axis, clamp (31) jaw (38) catches (11) enter the recesses (6) axially, locking the drive spindle in set angular position. The cutting tool, offered up axially to the protruding spindle in a holder-wrench (25), is locked onto it by turning against the cutting direction. A less than 120 deg turn in the direction of cutting, removes it again.
