Description

Technical Field

[0001] This utility model relates to the field of machine tool protective doors, and in particular to an irregularly shaped automatic tool changer door. Background Technology

[0002] The tool magazine provides storage space for cutting tools and precisely selects the required tool according to program control to complete the tool exchange. It is an indispensable core component in the process of achieving automated machining. For mill-turn machines, corresponding turning tool magazines and milling cutter magazines must be equipped. During the tool change process on the spindle, the tool changer door must be opened, and the tool changer arm of the tool changer mechanism rotates to change the tool on the spindle.

[0003] To reduce the overall size of the machine tool, the designers adjusted the layout of the bed and tool magazine. Specifically, they placed the turning tool magazine and the milling cutter magazine on the same side of the bed, ensuring a relatively compact layout. This resulted in a potential collision risk when changing turning and milling cutters on the same plane. The distance between the tool magazine and the tool changer is limited by the tool changer's travel distance, making it impossible to arbitrarily change the distance to separate turning and milling cutter changes onto different planes. This means that traditional flat-panel tool changers are unsuitable for the tool changing requirements of this type of compact machine tool layout. Summary of the Invention
