HOLDER FOR AUTOMATIC REPLACEMENT OF TOOL

摘要

FIELD: machine building.SUBSTANCE: holder comprises a tail in the form of a conical body. In the tail there is a cylindrical cavity, the length of which is equal to the length of the conical body. In it there are through longitudinal helical slots, arranged in parallel to each other via equal intervals in the direction matching the direction of the holder rotation. Ends of slots are limited with cylindrical surfaces with diameters equal to width of slots.EFFECT: increased accuracy of tool fixation in a machine spindle and reduced complexity of separation of conical body coupling with a conical hole in a spindle of the machine.1 dwg
