Apparatus for mounting a tool holder or like assembly to a backing structure

摘要

Apparatus for simple and precise positioning of a tool holder or like assembly on a backing structure, characterized by the tool holder and its backing structure having interfitting parts which interconnect by a sliding motion of one relative to the other. The interfitting parts include portions which provide, on contact, a precise datum control point, for location of said assembly, and other portions formed to accommodate discrepancies in the prescribed positions thereof relative said datum control point. The interfitting parts are so designed to enable a simple and automatic positioning of a tool holder or like assembly on a base support by a slip fit of one to the other.
