Description

Technical Field

[0001] The invention relates to the technical field of gantry machine tools, in particular to a gantry machine tool with a rapid tool magazine tool changing structure. Background Art

[0002] As an optional accessory for machine tools, the tool magazine features convenient and fast tool changes, which saves the operator from frequent manual tool changes, improving machine tool efficiency and shortening processing time. The tool magazine structure on existing machine tools generally has a tool magazine door to separate the tool magazine from the inner cavity of the machine tool, and then the tool changing function is realized by a cylinder or a tool arm. However, this tool changing structure has many movements. When changing tools, the automatic door of the tool magazine must be opened by the cylinder first, and then the tool magazine is pushed to the tool changing position by the tool magazine cylinder. Only then can the spindle return the tool and grab the tool to complete the tool change. In order to improve processing efficiency, existing processing machine tools often need to install multiple tools at the same time, thereby facilitating continuous processing with a group of tools during the processing process. For this reason, when changing tools, it is also necessary to continuously replace multiple tools. After positioning a single tool, the traditional tool magazine often needs to be reset to position the next required tool in order to improve the calculation efficiency of the controller and avoid calculation errors, resulting in a significant reduction in tool change efficiency.
