Tool change procedure.

In a chain type tool magazine with an upright body, the body is locked with a guide rail to form a path for the chain to run, and the guide rail provides contact support for the chain when it goes around, so that the chain can move stably. In order to avoid improper deflection of the moving chain, the guide rail of the known chain tool magazine is composed of an outer peripheral guide rail and an inner peripheral guide rail that extend in parallel and are arranged at intervals, and the chain is confined to the outer peripheral guide rail and the between the inner peripheral guide rails and controlled to detour along the path provided by the guide rails. However, the aforementioned guide rail is a fully enclosed track, that is, the outer peripheral guide rail and the inner peripheral guide rail are continuous structures, and the total length of the outer peripheral guide rail and the inner peripheral guide rail affects the construction cost and the total weight of the tool magazine. The aforementioned cost And the weight must be considered by the tool magazine manufacturer in the development and design. Secondly, most of the existing chain-type tool magazines are special-purpose tools, and the tool sleeves mounted on the chain are only suitable for the insertion and use of toolholders of a specific size, and are not suitable for combining with toolholders of other specifications and sizes. Therefore, the existing chain-type tool magazines The chain mechanism in the tool magazine is not universal, which reduces its practicality.

In view of this, the purpose of this creation is to provide a chain-type tool magazine, which can reduce the construction cost and reduce the weight of the tool magazine on the basis of not affecting the existing functions of the tool magazine.
