[0003] With the development of industrial manufacturing, product designs are becoming increasingly complex, and the required machining processes are also becoming more diverse. Different machining operations require different types and specifications of tool heads. For example, in the machining of automobile engine cylinder blocks, various machining operations such as milling, boring, and drilling are involved, and multiple tool heads are required. This requires the tool changing device to be able to quickly adapt to the frequent replacement needs of tool heads. The traditional tool changing method appears to be inefficient when faced with such complex tool head switching.
