Abstract

PURPOSE: To raise the working efficiency of a machine tool by enabling a tool to be fitted to and removed from the main shaft by only two simple actions of pushing and pulling.
CONSTITUTION: A holder 2 is fitted to the main shaft 1 of a multispindle machine tool by some public means. In the holder 2 plural number of steel balls 3 are housed, being held by a ring 4 so that they can move in the radius direction, but not slip out of the holder. A tool T is inserted and fitted to a sleeve 7, and, by setting the key 12 of an adjusting socket 11 to the groove 1a of the main shaft 1 and inserting it therein, the sleeve 7 touches the steel balls 3, the holder 2 being connected with the sleeve 7 by the action of a spring 10. The sleeve 7 can be removed easily by pulling the sleeve toward the tool T against the spring 10.
