Tool chain magazine

摘要

A tool chain magazine, in particular for program-controlled milling machines and machining centers, comprising a stationary supporting structure to which linear guiding devices, chain wheels, and a drive assembly as a rotary drive for at least one of the chain wheels are mounted. The tool chain comprises an endless magazine chain consisting of a series of chain links connected in an articulate manner to one another, wherein supporting and guiding elements are provided on each chain link, and each chain link has a respective socket as a holder for a tool taper. The base bodies of the chain links of the magazine chain are formed by the tool stations centrally disposed therein, and the front and rear connecting joints of the chain links are arranged in the longitudinal center axis of the magazine chain.
