APPARATUS FOR CHANGING TOOLS IN GRINDING MACHINES AND THE LIKE

摘要

A surface grinding machine wherein the spindle for grinding wheels is mounted on a slide which is reciprocable to and from a tool changing station. A transfer unit at the changing station has a head which is indexible on a base and has two aligned or crossing arms with discrete tool clamping mechanisms. Each clamping mechanism can accept a tool from the spindle in such orientation that the axis of the tool is horizontal, and the head is then indexed to change the orientation of the axis of the tool from horizontal to vertical before the tool is deposited in a selected carrier of a depository for tools. The depository is movable relative to the tool changing station to place a selected carrier into proper position for reception of a tool or for removal of a tool therefrom and/or to move the depository to and from a magazine for tools.
