Description

Technical Field

[0001] The utility model belongs to the technical field of automated processing equipment, and in particular relates to an automatic tool changing system for a composite processing center. Background Art

[0002] Common tool magazines for machine tools include disc tool magazines, chain tool magazines, storage tool magazines, etc. Existing storage tool magazines are mostly fan-shaped. When changing tools, the robot grabs the tools from the tool magazine to complete the automatic tool change of the machine tool; however, when loading the tools into the tool magazine, the operator must enter the tool magazine operation area to place the tools one by one into the tool positions of the tool magazine. In order to ensure the safety of the operator, the machine needs to be shut down, resulting in low working efficiency of the machine tool; secondly, in addition to standard tools, compound machining centers also use various non-standard tools and special extra-long and extra-wide tools. The existing tool magazines cannot realize the storage and automatic replacement of non-standard tools and special extra-long and extra-wide tools, and can only be realized through manual loading and unloading, which is labor-intensive and inefficient for workers.
