In the tool magazine of the CCK450 machining center, the actual machining requirements require the installation of 20 tools. All 20 tools are mounted on one cutter head, and the cutter head needs an intermittent indexing mechanism to drive. There are many mechanisms that can perform intermittent indexing movements, such as a ratchet pawl mechanism, a sheave mechanism, a partial gear mechanism, a swing mechanism, and a cam mechanism. In the magazine, the indexing intermittent motion mechanism used is a sheave mechanism.
