Cam-type automatic tool-exchanging apparatus having a shutter driving mechanism

摘要

A cam-type automatic tool-exchanging apparatus comprises; a housing; an input rotary shaft within the housing; a rotational-motion converting cam within the housing and rotationally driven by the input rotary shaft and outputting a rotational motion; a lifting/lowering-motion producing cam provided the housing and rotationally driven by the input rotary shaft and outputting a lifting/lowering motion; a tool-exchanging arm provided outside the housing and driven by the rotational motion and the lifting/lowering motion outputted for performing a tool-exchanging operation; a shutter provided outside the housing and to be opened/closed in accordance with the tool-exchanging operation; an opening/closing-motion producing cam within the housing and rotationally driven by the input rotary shaft and outputting a shutter-opening/closing pivotal motion for opening/closing the shutter; and a shutter-driving rotary shaft within the housing and outputting the shutter-opening/closing pivotal motion of the opening/closing-motion producing cam from inside of the housing to the outside.
