The first tool clamp driving mechanism moves the first tool clamp with the target tool shank to a tool preparation station, the first transfer mechanism drives the tool changing arm to move to a tool taking waiting station, and the second tool clamp driving mechanism drives the second tool clamp to rotate to face the tool taking station;
the second transfer mechanism drives the cutter taking sleeve to grab the target cutter handle on the first cutter clamp at the cutter standby station and moves to the cutter taking station, so that the second cutter clamp clamps the target cutter handle, and the cutter taking sleeve unloads the target cutter handle on the second cutter clamp;
the first shifting mechanism drives the tool changing arm to move to a tool changing waiting station, and the second tool holder driving mechanism drives the second tool holder with no load to rotate to be opposite to the tool changing station;
and the main shaft moves to a tool changing station, so that the second tool holder with no load clamps the to-be-returned tool shank, and the second tool holder driving mechanism drives the second tool holder with the target tool shank to rotate to the tool changing station, so that the main shaft finishes tool changing.
10. The tool changing method of claim 9, further comprising
The first shifting mechanism drives the tool changing arm to move to a tool taking waiting station, and the second tool holder driving mechanism drives the second tool holder to rotate to be opposite to the tool taking station;
the second transfer mechanism drives the cutter taking sleeve to grab the to-be-returned cutter handle on the second cutter holder at the cutter taking station and move to the cutter standby station, so that the first cutter holder clamps the to-be-returned cutter handle, and the cutter taking sleeve unloads the to-be-returned cutter handle on the first cutter holder.
